Oppo R5 preview. The thinnest smartphone in the world. Oppo showed smartphones N3 and R5

Lately, we have heard the slogan “The thinnest in the world” more than once, but the Oppo R5 phone will retain this title for a very long time - technology will not yet allow making the phone even thinner. The company's engineers decided to amaze the user on all fronts and presented a truly powerful competitor that can please you from any angle - the processor, camera, display, body and other parts are the best on the market. At the moment, there is no competitor on the Android platform that can compete with this smartphone in terms of performance, thinness and lightness of the body, so it definitely makes sense to buy a new product. It is very difficult to surprise the modern user; to do this, you need to present not just a powerful phone, it must be a real breakthrough in the market. And Oppo managed to make a breakthrough - Oppo R5 will open up enormous opportunities for you for work and entertainment, the Internet and communication.

Filling

The basis of the smartphone is the Qualcomm Snapdragon 615 processor, which is being used for the first time. You might mistakenly think that this is a simpler model compared to the Snapdragon 800, but in fact this processor is more powerful - it runs on eight Cortex A53 processing cores. Four Cortex A53 cores have a clock speed of 1.7 gigahertz, another four – 1 gigahertz. The cores can work either separately or together, delivering the highest performance of any Android smartphone. The graphics subsystem is Adren 405, which produces high-quality images on the phone’s display. The main advantage of this coprocessor is its support for DirectX 11.2 and Open GL ES3.0 software interfaces. Two gigabytes will support processor performance random access memory. The built-in memory for storing content is 16 gigabytes; there is no option to insert a memory card.

Design

The main advantage of the phone body is its thickness - only 4.85 millimeters. The previous “thintest phone” was 5.1 millimeters thick. Thanks to the thin body, the developers were able to significantly reduce the weight of the phone and bring it to 155 grams. The front panel is very stingy in terms of elements - there are only touch control keys, a webcam with sensors and a speaker grille. The back panel also doesn’t impress with any special features, just a camera with a flash, a company logo and that’s it. The side faces, despite their thickness, received hardware keys for controlling sound and locking.

Bonuses

The smartphone will delight its owner large display with a diagonal of 5.2 inches. The display resolution is 1920 by 1080 pixels, pixel density is 423 ppi. The matrix is made using AMOLED technology with the highest realistic color rendering. The 13-megapixel main camera has a Sony IMX214 sensor, autofocus, LED flash and optical image stabilization. The 5 megapixel front camera also takes excellent photos and videos. The phone runs on the Color OS 2.0 operating system based on Android 4.4 KitKat.

Bottom line

To accommodate the thickness of the device, a memory card slot and a mini-jack for headphones were removed. If a memory card is not particularly needed if you have an LTE connection and a heap cloud storage, then the loss of a headphone jack will be a big loss for many. With a thickness of 4.85 millimeters, the phone can easily be called the thinnest in the world, and fans of everything light and thin will definitely want it. In addition, the processor is currently the most powerful on the planet and gamers will be able to plunge into the gaming world with renewed vigor - the processor is 64-bit.

Oppo R5 comments and reviews

Today we will talk about a rather unusual project, which is made in stylish graphics, it has a lot of in...

On October 31, a presentation of Meizu took place in Moscow, which was dedicated to their return to the Russian market. ...

on a new 64-bit platform and in a record thin metal case

Developers' attempts to create the world's thinnest smartphone continue. Most recently, we looked at the extremely thin Tornado Slim smartphone from the Fly brand, which is well known to all Russians (which is, in fact, a copy of another ultra-thin smartphone, Gionee Elife S5.1). However, by that time it was already known about the announcement of even thinner models by the related Chinese companies Oppo and Vivo: the Vivo X5 Max and Oppo R5 devices proposed by these “sisters” have a thickness of 4.75 and 4.85 mm, respectively, which means Both of them are thinner devices than the familiar “record holder” of the Fly brand. In principle, we have already briefly introduced readers to the Oppo R5 model in a report from the site of the smartphone’s presentation in Beijing, and today we have the opportunity to carry out a full review of a commercial sample that has gone on sale, albeit not yet in our market.

At this point, it will be necessary to recall that last year’s attempt to organize the work of the Russian office of Oppo failed, but the Chinese have not lost hope of making a “reboot” in the new year. In Beijing, we met the new head of the company's future representative office in Russia, Mr. Jason, who plans to organize Oppo's official activities in our market.

This will happen, however, not earlier than next spring, so we borrowed a sample of the Oppo R5 for our experiments from the Asian market, where this smartphone began to be sold at the end of last year. However, there are practically no significant differences in the modification intended for other countries, with the exception of the lack of support for the Russian-language interface, so future buyers can fully appreciate all the capabilities of the new product using the example of the full-fledged commercial sample we are examining today.

Equipment

The packaging of Oppo R5 is completely identical in appearance and structure to the packaging of the company's latest flagship devices, for example, Find 7 or Find 7a. The box is completely plastic, it is square and flat, contains a plastic tray inside and several compartments underneath, which are also, in turn, filled with smaller cardboard boxes of the same size as the compartments. The accessory set consists of a massive charger large sizes (output current 5 V, 5 A), a thick Micro-USB connecting cable, a proprietary wired stereo headset with a thin round wire and intra-channel rubber ear pads, a proprietary paper clip, a plastic case, as well as several thin books of paper documentation.

Additionally, it is worth noting several points: firstly, the large size of the power supply with a high output current and the unusually thick cross-section of the Micro-USB connecting cable are due to the fast charging function supported by the smartphone. Secondly, the developers were unable to equip the thin Oppo R5 case with a standard audio jack with a diameter of 3.5 mm, so the headphone output here is organized through the only connector available in the smartphone - Micro-USB. Accordingly, an adapter is included with the headphones, that is, the supplied headphones themselves end in a standard jack, so they can be used in any other devices with a standard audio output. And thirdly, among other things, the kit included an additional “candy” - a protective case made of translucent matte plastic. With a case, of course, the device adds a little thickness, but still such care on the part of the manufacturer is pleasant. And in general, all this stylish packaging and its contents are arranged and presented in a rather pretentious way - immediately creating the most favorable mood for further acquaintance with the smartphone itself.

Appearance and ease of use

In terms of design, the ultra-thin Oppo R5 is no different from other similar devices: the same absolutely flat front and back surfaces without rounding, the same smooth wide metal sides with straight edges, the same slightly rounded corners. But there are also differences from the same Fly Tornado Slim, for example: in the Oppo R5, the camera module protrudes noticeably from the body, which is why technically the thickness of the body at the widest point of the smartphone turns out to be much greater than the record figures provided by the developers. Secondly, the smartphone turned out to be surprisingly heavy: our own measurements showed as much as 157 g, although the specifications indicate a not much lower figure (155 g). This moment, by the way, has an even more negative effect than it might seem at first glance. The fact is that since the smartphone body is so thin, many people find it cozy and comfortable to carry such a thin smartphone in their pockets, otherwise what’s the point of even touching on the topic of thickness? So, Oppo R5, although ultra-thin, is also a very large and heavy device that will not be so comfortable to place in a trouser pocket, not to mention the chest pockets of a shirt. Any pocket will pull unattractively under the weight of 157 g, and the width and length of the device are not at all small, and the sharp corners have very small roundings.

As for the aesthetic side of the issue, here, of course, everything is at its best: a thin body with an abundance of metal parts looks both advantageous and catchy, capable of looking decent both with an expensive suit and in a rich setting. From a practical point of view, the question of the convenience of everyday use of such a thin and heavy mobile device remains open: some people like the fact that the device fits comfortably in their pocket. On the other hand, holding a thin and heavy plate with slippery glass and equally slippery metal surfaces in the palm of your hand is not so convenient. In everyday life, handling a smartphone, for example, wiping its screen on your knee or lifting it from a table surface, is, of course, not as comfortable as it can be done with a device equipped with a thicker case with rough surfaces. But this is all a matter of habit: in the end, the iPhone 4 and 5 series with its straight metal edges were also completely inconvenient to lift from the table, but millions of users somehow got used to it.

By the way, to be fair, it is worth noting that the sides of the Oppo R5 are not entirely straight: the frame, made of metal, has a barely noticeable angle of inclination (Micro Arc Frame), so the device lying on its back, which has received the corresponding bevels on the sides, can even be lifted from the table more convenient than the notorious iPhone.

In general, so much attention is devoted to this metal side frame that the process of its production involves a huge number of different operations, including manual ones. To achieve a variable thickness of this metal rim (from 2.6 to 1.4 mm), hand polishing is also used after stamping.

The entire frame production process involves 55 different operations. It is worth noting that it is the color of this frame that determines the modifications of the model: in the standard configuration, the side frame has a silver color, and in the limited edition deluxe versions The frame is cast in gold. At the same time, the R5 body itself always remains white.

The Oppo R5 also has one more metal part in the body, even more noticeable than the side frame. This is a large metal plate on the back side, making up most of the back cover of the case. The cover is not entirely metal: there are plastic inserts at the top and bottom, which prevent the internal antennas from being shielded. So this time the developers did not have to take them out to the outer surface and place them in grooves, as is the case with the all-metal cases of other smartphones, such as the 6th generation iPhone, for example. The back cover, it should be noted, has a hard, pleasant to the touch, but matte and slightly rough coating, called “Dura Silk” by the company. Thanks to this coating, the back surface of the smartphone remains completely unmarked and provides a more comfortable grip on the palm.

Inside, it should be noted that the materials are also not easy: during the presentation in Beijing, the developers especially noted a certain special cooling system called Ice Nest, based on an unusual material that they called “liquid metal.” Now there are some clarifications on this matter. It turns out that between the processor and the graphite plate, which traditionally transfers heat to the smartphone chassis, thus dissipating heat, there is now an additional layer of material (metal, resins and other composite materials), which, when heated strongly, turns from solid to liquid. Oppo even talks about the R5 as "the first liquid-cooled smartphone." This “liquid metal” absorbs heat due to high thermal conductivity, and then distributes it over a larger area so that local overheating is not observed.

The body of the smartphone itself is monolithic and non-separable, so the method of attaching the SIM card is appropriate: the card is placed on a metal slide inside the side slot, and is removed by pressing a secret button using a special included key-clip. There is only one slot in the Oppo R5, only one Micro-SIM card is used, and there is no slot for a memory card. This is quite sad considering the fact that the smartphone also does not support connecting external flash drives via an OTG adapter. That is, the small amount of built-in memory (about 11 GB) allocated to the user for his personal needs is finite and cannot be expanded in any way.

The front panel of the smartphone is completely covered with a flat protective glass Corning Gorilla Glass 3, scratch resistant. In the upper part of the case, a longitudinal recess is cut right into the glass to accommodate the telephone speaker grille; next to it you can see the sensors and the front camera window. But such a useful element as an LED notification indicator was unfortunately not found here.

But there is even sadder news: the traditional row of three hardware touch buttons under the screen is not equipped with any backlight at all. That is, the pictograms are painted with silver paint directly on a white substrate, are poorly visible under glass that reflects in daylight, but in the twilight, of course, they are completely indistinguishable. Obviously, all this was done in order to save space in an ultra-thin case, however, in fairness it is worth noting that the same Fly Tornado Slim provides backlit buttons, a full 3.5 mm audio output, and even the camera module does not protrude beyond the body. All these little things make the Fly a little more convenient for everyday use than the Oppo R5. Although, again, it’s quite possible to get used to these kinds of little things and even learn not to notice them, but why put up with the inconvenience? It would be more convenient with backlighting, that's a fact.

Two mechanical keys are located on one left side, one next to the other. Both buttons - volume and lock - protrude to a sufficient height, are easy to feel blindly, the stroke is quite long and elastic, the response is clear, there are no special complaints about the implementation of mechanical controls. However, it is worth noting that different keys located very close to each other sometimes, especially in a hurry, cause confusion: you can blindly press lock instead of volume, for example, this happens. It’s not for nothing that the developers originally mobile devices The keys have always been spaced out on different sides, it’s much more convenient. Nowadays, many are trying to stand out, to do something differently from the norm, but this does not always turn out to be convenient.

The universal Micro-USB connector is located at the bottom. It also plays the role of an audio output for headphones, since the developers were unable to fit a standard jack with a diameter of 3.5 mm here. But this connector does not support the OTG mode for connecting external devices. There are no plugs or covers on the case; the device is not equipped with protection against water and dirt. There is no strap mount on the Oppo R5 case either. As for the colors, it is known that in addition to the white version with a silver metal frame, as in our photographs, there is also a golden version of the frame on sale. In both cases, the body itself always remains white.

Screen

The Oppo R5 smartphone is equipped with an AMOLED touch matrix with Gorilla Glass protection. The screen dimensions are 65x115 mm, diagonal - 5.2 inches, resolution - 1920x1080 pixels. The pixel density is 423 ppi.

The width of the side frames from the edge of the screen to the edge of the body is about 4.5 mm - the frames are not that thin; around the screen you can see a thick black border about a millimeter and a half wide. The width of the top and bottom edges is about 15-16 mm. The brightness of the display can be adjusted manually, or you can use automatic adjustment based on the operation of the light sensor. Multi-touch technology allows you to process 3 simultaneous touches; if you turn off support for certain gestures in the settings, then their number increases to 10. The smartphone also has a proximity sensor that blocks the screen when you bring the smartphone to your ear. The screen can be activated by double tapping the glass.

A detailed examination using measuring instruments was carried out by the editor of the “Monitors” and “Projectors and TV” sections, Alexey Kudryavtsev. Here is his expert opinion on the screen of the sample under study.

The front surface of the screen is made in the form of a glass plate with a mirror-smooth surface that is scratch-resistant. Judging by the reflection of objects, the anti-glare properties of the screen are comparable to the screen properties of Google Nexus 7 (2013) (hereinafter simply Nexus 7). For clarity, here is a photograph in which a white surface is reflected in the switched off screens (on the left - Nexus 7, on the right - Oppo R5, then they can be distinguished by size):

The screen of the Oppo R5 is a little lighter (brightness according to photographs is 114 versus 105 for the Nexus 7) and has a brownish tint. Note that the reflection from bright objects in the Oppo R5 screen has a pale bluish halo that is slightly more pronounced in the transverse direction. The ghosting of reflected objects on the Oppo R5's screen is very weak, indicating that there is no air gap between the layers of the screen. Due to the smaller number of boundaries (glass-air type) with very different refractive indices, screens without an air gap look better in conditions of strong external illumination, but their repair in the case of cracked external glass is much more expensive, since the entire screen has to be replaced. The outer surface of the Oppo R5 screen has a special oleophobic (grease-repellent) coating (effective, but slightly worse than that of the Nexus 7), so fingerprints are removed much more easily and appear at a slower rate than with regular glass.

When the white field was displayed in full screen and with manual brightness control, its maximum value was 330 cd/m², the minimum was 3 cd/m². You also need to take into account the fact that in this case, the smaller the white area on the screen, the brighter it is, that is, the actual maximum brightness of the white areas will almost always be higher than the specified value. For example, when outputting white on half the screen (and black on the other half), the maximum brightness with manual adjustment increases to 385 cd/m². As a result, readability during the day in the sun should be at a fairly good level (there was no opportunity to test it). The reduced brightness level allows you to use the device even in complete darkness without any problems. There is automatic brightness adjustment based on the light sensor (it is located to the right of the front speaker slot). You can make adjustments to the operation of this function by moving the brightness adjustment slider. Below, for three conditions, we present the screen brightness values for three values of this setting - for 0, 50 (approximately) and 100%. In complete darkness in automatic mode, the brightness is reduced to 3, 16 and 69 cd/m², respectively (the first is a bit dark, the second is normal, the third is bright), in an office illuminated by artificial light (approximately 400 lux) the brightness is set to 31, 96 and 178 cd/m² (the first is a bit dark, the other two are normal), in a brightly lit environment (corresponding to bright daylight outdoors, but without direct sunlight - 20,000 lux or a little more) - increases to 330 cd/m² regardless of position slider (this is the maximum that is needed). The results obtained allow us to conclude that correct operation light sensor.

Only at low brightness levels there is modulation with a frequency of 220 Hz. The figure below shows the dependence of brightness (vertical axis) on time (horizontal axis) for several brightness values:

It can be seen that at maximum and average brightness the modulation amplitude is minimal, its frequency is 55 Hz (screen refresh rate), so there is no visible flicker. However, with a strong decrease in brightness, modulation appears with a frequency of 220 Hz and a large relative amplitude. Therefore, at low brightness, the presence of modulation can already be seen in a test for the presence of a stroboscopic effect or simply with rapid eye movement. Depending on individual sensitivity, this flickering may cause increased fatigue.

This screen uses an AMOLED matrix - active matrix organic light-emitting diodes. A full-color image is created using subpixels of three colors - red (R), green (G) and blue (B), but there are twice as many green subpixels, which can be referred to as RGBG. This is confirmed by a fragment of a microphotograph:

For comparison, you can see the gallery of microphotographs of screens used in mobile technology.

In the fragment above you can count 4 green subpixels, 2 red (4 halves) and 2 blue (1 whole and 4 quarters), and by repeating these fragments, you can lay out the entire screen without breaks or overlap. For such matrices, Samsung introduced the name PenTile RGBG. The manufacturer calculates the screen resolution based on the green subpixels; based on the other two, it will be two times lower. The location and shape of the subpixels in this version is similar to that in the case of the screen of the Samsung Galaxy S4 and some other newer devices from Samsung (and not only) with AMOLED screens. This version of PenTile RGBG is better than the old one with red squares, blue rectangles and stripes of green subpixels. However, some unevenness of contrast borders and other artifacts are still present. However, due to the high resolution, they have a minimal impact on image quality.

The screen is characterized by excellent viewing angles, although the white color, when deviated even at small angles, acquires a slight blue-green tint, and at some angles turns slightly pink, but the black color is just black at any angle. So black that the contrast parameter is simply not applicable in this case. When viewed perpendicularly, the uniformity of the white field is good. For comparison, here are photographs in which the same images are displayed on the screens of the Oppo R5 and the second comparison participant, while the brightness of the screens is initially set to approximately 200 cd/m², and the color balance on the camera is forced to switch to 6500 K. White field:

Note the good uniformity of brightness and color tone of the white field. And a test picture:

The color balance of the screens varies slightly and the colors on the Oppo R5 are oversaturated and unnatural. Now at an angle of approximately 45 degrees to the plane and to the side of the screen. White field:

The brightness at an angle for both screens has noticeably decreased (to avoid strong darkening, the shutter speed has been increased compared to the previous two photographs), but in the case of the Oppo R5 the drop in brightness is much less pronounced. As a result, with formally the same brightness, the Oppo R5 screen visually looks much brighter (compared to LCD screens), since you often have to look at the screen of a mobile device from at least a slight angle. And a test picture:

It can be seen that the colors have not changed much on both screens and the brightness of the Oppo R5 at an angle is noticeably higher.

Switching the state of the matrix elements is performed almost instantly, but at the switching edge there may be a step approximately 18 ms wide (which corresponds to the screen refresh rate). In some conditions, the presence of such a step can lead to plumes trailing moving objects, but in normal use these artifacts are difficult to see. Quite the contrary - dynamic scenes in films on OLED screens are distinguished by high clarity and even some “jerky” movements.

The gamma curve, constructed using 32 points with equal intervals based on the numerical value of the shade of gray, did not reveal a blockage either in the shadows or in the highlights. The index of the approximating power function is 2.33, which is higher than the standard value of 2.2, while the real gamma curve practically does not deviate from the power dependence:

Let us recall that in the case of OLED screens, the brightness of image fragments dynamically changes in accordance with the nature of the displayed image - it decreases for generally light images. As a result, the resulting dependence of brightness on hue (gamma curve) most likely slightly does not correspond to the gamma curve of a static image, since the measurements were carried out with sequential display of shades of gray on almost the entire screen.

The color gamut is very wide:

The component spectra (that is, the spectra of pure red, green and blue) are very well separated:

Note that on screens with a wide color gamut, without appropriate correction, the colors of regular images optimized for sRGB devices appear unnaturally saturated. The balance of shades on the gray scale is not ideal, but, in general, acceptable. The color temperature is above 6500 K, and the deviation from the blackbody spectrum (ΔE) remains below 10 units over most of the gray scale, which is considered a good indicator for a consumer device. At the same time, color temperature and ΔE change little from hue to hue - this has a positive effect on the visual assessment of color balance:

(The darkest areas of the gray scale can in most cases be ignored, since color balance there is not very important, and the error in measuring color characteristics at low brightness is large.)

Let's summarize. The screen has a fairly high maximum brightness and has good anti-glare properties, so the device can most likely be used outdoors even on a sunny summer day without any problems. In complete darkness, the brightness can be reduced to a comfortable value. It is permissible to use a mode with automatic brightness adjustment, which works quite adequately. The advantages of the screen include a good oleophobic coating and a color balance close to standard. At the same time, let us recall the general advantages of OLED screens: true black color (if nothing is reflected in the screen), good uniformity of the white field, noticeably less than that of LCDs, and a drop in image brightness when viewed at an angle. The disadvantages include screen flickering, which appears at low brightness. For users who are particularly sensitive to flicker, this may cause increased fatigue. Negative properties include an excessively wide color gamut, which makes ordinary images look unnatural. However, overall the screen quality is high.

Sound

Oppo R5 sounds good, but nothing more. Top smartphones of this brand have always been famous for their wonderful, high-quality and powerful sound, perhaps the best on the mobile device market, but Oppo R5 is not that case. To save space, only one speaker was built into the smartphone body, which serves as both a conversational speaker and an external speaker. That is, the device produces sound through the very auditory slit located on the front panel, intended for the ear. Accordingly, the sound produced by this speaker is not so powerful and loud, although it remains clear across the entire frequency spectrum. However, the speaker cannot boast of any particular power; the maximum volume is not too high, there is not an abundance of low frequencies, although overall the sound is clear and pleasant.

As for connecting headphones, as in the case of its predecessor, Oppo Finder, this device also did not have room to embed a full-fledged 3.5 mm jack. However, the sound in the headphones is not bad, clear throughout the entire frequency range, the maximum volume is sufficient, but there is not an abundance of low frequencies here. To play melodies in a smartphone, there is a proprietary audio player, rich in sorting capabilities, etc., but practically devoid of options for adjusting the sound quality itself. Only when playing on headphones does it become possible to add some sound enhancements by turning on the Dirac HD Sound mode.

The main rear camera is equipped with a 13-megapixel Sony Exmor IMX214 back-illuminated CMOS sensor with f/2.0 aperture. The module did not fit entirely into such a thin body, so the rear camera window protrudes above the surface of the body. Unlike its flagship Find 7/7a series, this device does not have a dual flash and does not have the ability to shoot video in 4K resolution.

The camera settings menu is organized in the simplest way in the form of a scrolling list with collapsing sub-items; everything is drawn quite clearly and clearly, but this menu differs in organization from its top-end counterparts, where all items are combined in the form of matrix squares. Additional shooting modes include panorama and HDR; there are also a lot of special modes, such as night photography, beautify, and even a specific HD picture mode, in which frames are interpolated to a resolution of 24 megapixels and even 50 megapixels. More practical is the professional mode with the function of separating focus points and autoexposure (AF/AE separation) and the ability to manually select the metering point. Two frames appear on the display: square and round. The square is responsible for the focusing point, and the circle is for the exposure metering point. To align the exposure on a specific object, you just need to move the round frame over that object, and the camera will set the desired exposure. By the way, you can add other modes by downloading them through the appropriate service via the Internet.

The camera can shoot video; there are several resolutions to choose from, up to a maximum of 1080p; no 4K or 60fps are provided. There is only the possibility of specific shooting in Slow Motion mode. Examples of test videos are presented below.

	The first photo shows a rather serious focus error.

	Sharpness is generally quite good, if it is even appropriate to talk about it, since most parts of the frame are covered with areas of out of focus, and tree branches sometimes appear double. But where there is sharpness, it is not bad.
	The sharpness in the central part is not bad, but there are too many out-of-focus objects in the periphery.

	It is difficult to identify any stable areas of blur. The camera simply selectively processes objects.
	The camera copes poorly with indoor photography.
	Another example of a not very good macro.
	Even on a sunny day, the blur zones do not disappear.
	For some reason, a 50 megapixel mode was added to the smartphone. The picture looks like the result of a banal interpolation.

If the manufacturer sets good cameras to its flagships, then it may well save money on younger models. And it's a shame. With all its capabilities, Oppo does not consider it necessary to install good cameras even in almost flagship models.

Much could be forgiven for the camera and hope that it will still be completed. But before us is a ready-made sample, but there are many problems. If the sloppy noise reduction can still be forgiven, then the problems with optics and focusing are no longer there. Focus can be corrected by software (at least, theoretically, and one would hope so), but still the camera does not always miss the focus, and this complicates the diagnosis. Not very sharp optics and a weak sensor significantly aggravate the situation.

In summary, the camera may be suitable for undemanding documentary shooting, but you will have to carefully monitor it.

Telephone and communications

The smartphone operates in most bands of modern networks 2G GSM, 3G WCDMA, LTE TDD and LTE FDD Cat4, supporting frequencies for Russia with a theoretical maximum download speed of up to 150 Mbit/s. In practice, with SIM cards from domestic operators, the smartphone is reliably registered and works in 4G networks. The network capabilities of the device are excellent: it supports Qualcomm VIVE Wi-Fi 802.11a/b/g/n/ac technology with the ability to operate in two bands (2.4 and 5 GHz); As a standard, you can organize a wireless access point via Wi-Fi or Bluetooth channels; there are Wi-Fi Direct and Wi-Fi Display modes. But NFC, traditionally for the “true Chinese”, is not supported, and there is no OTG support.

The navigation module works with GPS/A-GPS, domestic Glonass and Chinese satellite system Beidou (BDS). There are no complaints about the navigation equipment, the satellites are located quickly, the operation is stable and does not cause any complaints. It is worth noting that the device also contains a magnetic field sensor, on the basis of which the electronic compass of navigation mapping programs usually operates.

There were no spontaneous reboots/shutdowns observed during testing, there are no problems with this, the interface works very quickly, no delays or slowdowns were noticed. There is no support for the Russian language for virtual keyboards, just as there is no support for the user interface itself, but this, naturally, will be corrected in official deliveries for our market. When dialing a number, SmartDial is supported with search by the first letters in contacts. It is possible to reduce the area of the working screen for ease of operation with the fingers of one hand.

OS and software

Oppo R5 runs natively on Google's software platform Android versions 4.4.4, with the proprietary Color OS shell version 2.0 installed on top. The interface traditionally does not have a separate menu for installed programs, all applications are distributed across desktops mixed with widgets, folders are supported. The shell is full of all sorts of improvements and additional functions. A lot of attention is paid, as usual, to controlling gestures: there are so many different possibilities here that several pages of instructions are devoted to studying them, and you can also set your own unique combinations. There are also well-designed energy-saving and guest operating modes; There is an extensive section dedicated to smartphone protection; there is even a pre-installed antivirus and the ability to password protect individual applications. There are many pre-installed additional programs, but most of them are not applicable without knowledge of Chinese and without the ability to create accounts in local services. In general, the shell in Oppo R5, although new version, but looks almost the same as in the flagship Find 7/7a devices.

Performance

The Oppo R5 hardware platform is based on the new eight-core Qualcomm Snapdragon 615 (MSM8939) single-chip system (SoC). This recently announced 64-bit platform is made using big.LITTLE technology, where four Cortex-A53 processor cores are adjacent to four of the same Cortex-A53 cores, but these “fours” differ maximum frequency work. Depending on the nature and degree of load, either 4 “junior” or 4 “senior” (up to 1.5 GHz) cores are turned on, which saves energy. The Adreno 405 video accelerator with a frequency of up to 550 MHz is responsible for graphics processing here. The Snapdragon 615 SoC is made using a 28 nm process technology, belongs to the mid-level category, does not differ in particular power and performance, a full list of characteristics can be found.

The smartphone's RAM capacity is 2 GB. The device has 16 GB of flash memory, of which about 11 GB is available for user needs, and the rest is reserved for the system and applications. The amount of memory in a smartphone cannot be increased using cards - the Oppo R5 does not support them. The mode for connecting external devices to the Micro-USB (OTG) port of the device is also not supported.

According to the test results, the eight-core Oppo R5 hardware platform showed average results, approximately at the level of the alternative eight-core MediaTek MT6592, or even slightly lower. According to AnTuTu, the performance of a smartphone does not rise above 30K in AnTuTu v 5.x, while for top solutions this value is now 40-45K. There is nothing special to add here; the platform is far in its capabilities from the most productive modern Qualcomm Snapdragon 800 series platforms, just as it is far from the fresh flagship MediaTek MT6595. The destiny of devices with such filling is a confident average level, nothing more. Nevertheless, the smartphone described today is quite powerful; the performance of the eight-core platform will be enough to perform most tasks for a long time.

Testing in latest versions comprehensive tests AnTuTu and GeekBench 3:

For convenience, we have compiled all the results we obtained when testing the smartphone in the latest versions of popular benchmarks into tables. The table usually adds several other devices from different segments, also tested on similar latest versions of benchmarks (this is done only for a visual assessment of the obtained dry figures). Unfortunately, within the framework of one comparison it is impossible to present the results from different versions of benchmarks, so many worthy and relevant models remain “behind the scenes” - due to the fact that they once passed the “obstacle course” on previous versions test programs.

Testing the graphics subsystem in 3DMark game tests,GFXBenchmark, and Bonsai Benchmark:

When testing in 3DMark, the most powerful smartphones now have the ability to run the application in Unlimited mode, where the rendering resolution is fixed at 720p and VSync is disabled (which can cause the speed to rise above 60 fps).

Browser cross-platform tests:

As for benchmarks for assessing the speed of the javascript engine, you should always make allowance for the fact that their results significantly depend on the browser in which they are launched, so the comparison can only be truly correct on the same OS and browsers, and this is possible during testing not always. For Android OS, we always try to use Google Chrome.

Playing video

To test the omnivorous nature of video playback (including support for various codecs, containers and special features, such as subtitles), we used the most common formats, which make up the bulk of the content available on the Internet. Note that for mobile devices it is important to have support for hardware video decoding at the chip level, since it is most often impossible to process modern options using processor cores alone. Also, you shouldn’t expect a mobile device to decode everything, since the leadership in flexibility belongs to the PC, and no one is going to challenge it.

According to the testing results, Oppo R5 was not equipped with all the necessary decoders, in this case audio ones, which are necessary for full playback of most of the most common files on the network. Previously, this issue was partially resolved by installing the popular third-party player MX Player. True, now, due to licensing problems, support for the AC3 sound codec, used in the vast majority of video content on the Internet, has been removed, so users may lose sound when viewing their files. In principle, you can independently search for a custom codec for this player on the Internet, and then download it to your smartphone and install it as an alternative. However, for an inexperienced user such manipulations are complex and very inconvenient. Alternatively, you can simply install and use another player from the many available in the online store Google Play. For example, VLC for Android beta without any problems and additional settings immediately plays all our test files.

Further testing of video playback was performed Alexey Kudryavtsev.

We did not find the MHL interface, like Mobility DisplayPort, in this smartphone, so we had to limit ourselves to testing the output of video files on the screen of the device itself. To do this, we used a set of test files with an arrow and a rectangle moving one division per frame (see “Method for testing video playback and display devices. Version 1 (for mobile devices)”). Screenshots with a shutter speed of 1 s helped determine the nature of the output of frames of video files with various parameters: the resolution varied (1280 by 720 (720p) and 1920 by 1080 (1080p) pixels) and frame rate (24, 25, 30, 50 and 60 frames/ With). In the tests we used the MX Player video player in the “Hardware” mode. The test results are summarized in the table:

720/30p Fine No 720/25p Fine No 720/24p Great No

Note: If in both columns Uniformity And Passes Green ratings are given, this means that, most likely, when watching films, artifacts caused by uneven alternation and frame skipping will either not be visible at all, or their number and visibility will not affect the viewing comfort. Red marks indicate possible problems related to the playback of the corresponding files.

According to the criterion of frame output, the quality of playback of video files on the screen of the smartphone itself is good, since frames (or groups of frames) can (but are not required) be output with more or less uniform alternation of intervals and without skipping frames. With the exception of 60 fps files, in which many frames are dropped due to the non-standard screen refresh rate (55 Hz). When playing video files with a resolution of 1920 by 1080 pixels (1080p) on a smartphone screen, the image of the video file itself is displayed exactly along the border of the screen, one to one in pixels, that is, in the original resolution. On the test worlds, the features of PenTile appear - the vertical world through the pixel looks like a grid, while the horizontal world with stripes through the pixel has a typical greenish tint. The brightness range displayed on the screen corresponds to the standard range of 16-235 - in the shadows, only a couple of shades closest to black do not differ from it in brightness, in the highlights all gradations of shades are displayed.

Battery life

The lithium-polymer battery installed in the Oppo R5 has a very small capacity for modern smartphones of only 2000 mAh, which is logical, because it is problematic to fit a large battery into such a thin case. The screen of this model, as the most energy-intensive element of any smartphone, is huge both in area and in resolution, so it is quite logical that the device showed quite modest, although not disastrous, results during testing battery life in the most common modes of use. Obviously, this is also due to the better optimization of the completely new 64-bit Qualcomm platform: evolving, new mobile systems becoming more and more economical every time. The results are summarized in a table.

	Battery capacity	Reading mode	Video mode	3D Game Mode
Oppo R5	2000 mAh	12:00 pm	7:00 am	2 hours 20 minutes
Fly Tornado Slim	2050 mAh	10:30 a.m.	7:00 am	3 hours 10 minutes

Continuous reading in the FBReader program (with a standard, light theme) at a minimum comfortable brightness level (brightness was set to 100 cd/m²) lasted until the battery was completely discharged for about 12 hours, and when continuously watching videos in high quality(720p) with the same brightness level via home Wi-Fi network The device lasted 7 hours. In game mode, the smartphone functioned for about 2.5 hours. It is worth noting that the device supports the fast charging function; for this purpose, the kit includes a powerful power supply with an output current of 5 A and a thick, reliable connecting cable. In half an hour, using the included charger, you can charge the battery up to 75%; a full charge lasts just over an hour. In principle, Oppo calls this technology VOOC, implying that it is its own development. However, most likely, it is based on the standard proprietary Qualcomm Quick Charge 2.0 technology, supported by the new platform of this manufacturer. Many manufacturers prefer to pass off similar developments from Qualcomm as their own, and even give them their own unique names. Qualcomm doesn't mind.

Bottom line

The Oppo R5 is not a flagship device in terms of characteristics - for this it does not have a sufficiently large number of functions and capabilities. The screen is good, the design is too, but everything else, including the performance of the hardware, the quality of shooting, the sound part, and the modest battery - all these are signs of an average smartphone. It is quite difficult to talk about the cost of the device during a crisis period with rising prices for equipment, and this new product is not sold in our stores, at least not yet. But in the end, it’s the price that will decide everything: if a smartphone can be purchased at an average price, then the device will certainly be interesting to purchase, at least for its unusual design and appearance. If sellers decide to sell the device at the price of a flagship device, to increase its price, focusing on the expensive design and record thickness of the case, then completely different arguments will be used. Oppo R5 is still more of a fashion model, but not a universal mobile assistant or even a powerful multimedia device. For versatile and even just comfortable use, a smartphone will at least not have enough internal memory, because there is no support for memory cards and OTG, which means that the space for movies, photos and music is seriously limited. However, for those for whom all of the above is not a decisive factor, but the image component comes first, this stylish ultra-thin smartphone is suitable.

The Chinese company Oppo held a presentation of its new smartphones scheduled for October 29. Among them was the expected N3 with a rotating camera, as well as the R5 - the new “” (case thickness is only 4.85 mm).

The thickness of its case is a record 4.85 mm, the available space was enough to fit 2 GB of RAM, a 64-bit Snapdragon 615 chip with a clock frequency of 1.5 GHz and a 2000 mAh lithium-polymer battery.

Oppo R5 has a 5.2-inch display with Full HD resolution (423 ppi), the device weighs 155 grams. The OS in the new product is Android 4.4.4 with the proprietary Color OS 2.0 shell. The gadget is also equipped with a main 13-megapixel camera and an additional 5-megapixel photo module, which is suitable for taking selfies and video calling.

The Oppo R5 smartphone supports LTE networks. Its recommended price is $500, but there is no information on the start date of sales yet.

Also at the presentation in Singapore, Oppo showed the N3 smartphone with a camera that rotates 206 degrees. The module moves automatically depending on the selected shooting mode (for example, when taking a 64-megapixel panorama).

Oppo N3 is equipped with a 4-core Snapdragon 801 chip clocked at 2.5 GHz, a 5.5-inch Full HD display (400 ppi), 2 GB of RAM and 32 GB of internal memory. The manufacturer promises to introduce a model with two SIM card slots in the future.

Like the Oppo R5, the N3 has a lithium polymer battery, but its capacity is 3000 mAh. Both new products are capable of restoring 75% of the charge in 30 minutes (Oppo VOOC technology is used), and in 5 minutes of charging they can provide two hours of talk time. The dimensions of the smartphone are 161.2×77×9.9 mm, weight – 192 g. Its recommended price is $650.

Oppo R5 is an incredibly thin and beautiful smartphone with a high-quality build, balanced characteristics, an excellent display and a very attractive price.

Design, keys and external interfaces

Unlike most smartphones, the Oppo R5 has only one design option - the device is sold in a white and silver metal case.

The front part of the device, with the exception of the speaker grille, is covered by a protective cover. Below it is a display surrounded by a white frame, three touch keys, proximity/light sensors and a front camera.

The side edge of the smartphone is made of silver metal – it contains all the physical keys and external interfaces of the device.

The back of the Oppo R5 is two-tone: at the top and bottom there are narrow inserts made of glossy white plastic, and the remaining space is occupied by a silver metal cover on which the chrome Oppo logo is located.

In general, the design of the Oppo R5 is stylish and memorable: straight body lines, a thin profile, pleasant design and interesting design solutions immediately make it clear that this is an image model.

All physical keys of the Oppo R5 are located on the right side of the device: at the very top there is a rocker for adjusting the volume, and a little lower is the power / lock button of the smartphone. Also under the device display you can find a panel with three touch keys: “List running applications", "Home" and "Back".

The Oppo R5 has standard connectors: there is an audio jack on the top end, a microSD slot on the bottom, and a SIM card tray is hidden on the left side.

Hardware and battery

The Oppo R5 hardware is based on a platform from Qualcomm: the smartphone uses the Qualcomm Snapdragon 615 (MSM8939) SoC, which includes 8 Cortex-A53 cores and an Adreno 405 video accelerator. The configuration is complemented by 2 gigabytes of RAM and a 16 gigabyte flash drive.

The hardware performance of the Oppo R5 is at a good level: the smartphone confidently handles all compatible applications and games and provides high operating speeds operating system and pre-installed programs.

It has a nominal capacity of 2000 mAh. Due to the small battery capacity, the smartphone demonstrates rather modest battery life: in reading mode the device lasts about 12 hours, watching videos drains the battery in 7-8 hours, and modern demanding games - in just 2-3 hours. However, even despite such results, the Oppo R5, with very active use, almost always lasts until the evening, which is a good result for a modern smartphone.

Display

Oppo R5 is equipped with a large display with a diagonal of 5.2 inches and a resolution of 1920 by 1080 pixels. This display is based on a SuperAMOLED matrix with a large reserve of brightness, high contrast, wide viewing angles, but rather inaccurate color reproduction with oversaturated colors and an excessively wide color gamut, which is much wider than the sRGB reference space.

Capacitive has good accuracy and responsiveness. The touch glass recognizes 3 simultaneous touches, but when special gestures are activated in the smartphone settings, the touchscreen can recognize up to 10 simultaneous touches.

In general, the main advantages of this smartphone are: even despite the oversaturated colors, this screen is ideal for games, movies and other multimedia entertainment.

Operating system and pre-installed applications

The operating system in Oppo R5 is ColorOS 2 based on Android 4.4 mobile OS. This shell does not have an application menu, but it supports themes and new gestures, has a nice design and good ergonomics.

Pre-installed programs are represented by a standard set of software from Oppo, which includes an application for making calls, maps, a browser, a messaging application, mail client And so on. Among all this variety of applications, the convenient one deserves special attention. file manager, theme manager and a good antivirus.

Conclusion

As a result, Oppo R5 is an excellent fashion smartphone, which, unfortunately, is not sold in Russia. If you are not afraid to buy smartphones in China and are ready to polish up its software (for example, Russify and install the usual software from Google), then the Oppo R5 will be an excellent purchase for you - in terms of all its characteristics, it is one of the most interesting and high-quality smartphones in its price segment.
