Test Oppo Reno2: the brand's most successful smartphone

Presentation

After having stammered at its beginnings in our regions, Oppo seemed to have found its marks. With the Reno2, the BBK Electronics firm intends to transform the trial, in the "high-end killers" category, by offering a smartphone identical in design, but with a new configuration and a redesigned photo component.

Lancé on October 18 at 499 € with its new photo module and its "gaming" processor, will it stand up to the best of the genre such as theGoogle Pixel 3a XL, the Samsung Galaxy A70, or the brand newXiaomi Mi 9T Pro, the new reference of the genre.

Ergonomics and design

For Oppo, the models follow one another and look (almost) the same. It's quite simple, apart from a few cosmetic adjustments, the Reno2 looks just like the "classic" Reno or the Reno 10x and Zoom, and that's not a big deal. The mobile is rather successful, the all-glass finishes are exemplary, especially the curved back that makes it easy to grip. The photo modules are completely integrated in the camera and do not overflow. Like his elders, Oppo has wisely placed a steel ball in the center of his mobile to protect the glass from small falls and scratches.

selfies module is always placed in a retractable shutter and, even if we appreciate the small "wow" effect produced by the mechanism, this system thickens and makes the terminal heavier, while depriving it of a waterproof certification. Finally, having a moving part - even guaranteed for 300,000 openings - always entails a slight risk of breakage. To prevent this risk a little better, as soon as the smartphone detects a fall, even of 5 cm, the module folds up automatically. This system allows the 6.5-inch slab to occupy almost the entire front surface of the device (about 87% according to our calculations), and we are not displeased with this aesthetic effect.

Oppo holds on to the retractable selfies module.

La connection consists of a USB-C port and a 3.5 mm mini-jack socket. The phone is capable of holding two nano-SIM cards, or a single SIM and a microSD card. This extension can increase the already large capacity of 256 GB. For unlocking, Oppo continues to bet on an optical fingerprint sensor placed under the panel. While there are more responsive systems, it is clear that the Chinese manufacturer has improved and its solution is working quite well.

Audio

La 3.5 mm mini-jack socket doesn't bother with frills. Oppo has removed the "Real Sound" optimization that we found unsavoury. The Reno2 port thus has no major flaws. Distortion is very well contained and the dynamic range is wide enough to let you hear the nuances of a song.

Quant to crosstalk, well managed, it ensures a faithful stereo restitution. We just regret a power that, without being weak, is a little bit just to feed really decently the most greedy headphones.

only one loudspeaker is not particularly bad, but it obviously doesn't allow stereo restitution, and we must avoid pushing it to the limit to avoid saturation.

Andalle très lumineuse

L's Oppo Reno2 display is based on a 6.5-inch Amoled panel in FHD+ definition (2400 x 1080 dpi or 401 dpi). This display, which almost entirely occupies the front of the smarphone, has proven to be excellent in more than one way. To take full advantage of the qualities of this panel, first of all, the color temperature should be set to "Warmer" and the color mode to "Soft", otherwise the measured temperature reaches 7,606 K, which is quite far from the video standard (6,500 K). This results in rather cold colors.

Antimes in "Warmer", the measurements are much more correct. The temperature drops to 6,799 K and gives a more natural hue. In any case, the Delta E measured at 2.4 indicates that the colorimetric drift is contained enough so that the human eye does not perceive it. Only turquoise blue and dark green exceed 4 in this range.

À this good colorimetry adds a really remarkable maximum luminosity. Measured at 737 cd/m², it places Reno2 in the top 10 brightest tiles passed by our lab, and we had the luxury of ejecting the iPhone 11 Pro from the ranking. And with a reflectance rate below 50%, this Oppo remains clearly readable in direct sunlight. At night, the minimum brightness (2.3 cd/m²) should not be too disturbing. Magic of the Oled, the contrast is almost infinite and the remanence imperceptible. As for the tactile delay, it reaches 71 ms, which is quite low.

Performances

Oppo Reno2 may be a mid-range smartphone, but it doesn't forget to perform. To do so, the BBK branch has opted for a gaming oriented SoC, the Snapdragon 730G, a software-optimized version of the 730, which combines 8GB of RAM and the Adreno 618 graphics chip to run Android 9. All the basic tasks of the terminal run without any slowdown.

Passé in our performance test, the Reno2 is also doing very well. In the RAM test, the Reno2 scored 87.08, a very honest result. However, it does not do as well as the Samsung Galaxy A80, which climbs to 95.38 with a "classic" Snapdragon 730 and 8GB of RAM.

For In the game part, the result is the same: while the A80 gets 82.64, the Reno2 only reaches 75.84 points. Oppo's device managed to maintain, on average, 42 frames per second, while Samsung's mobile stayed at 46 fps.

Étant since this Reno2 has a SoC stamped, we investigated whether it was possible to improve its results by activating the "high performance" mode. To our surprise, for the RAM test, the results differ only slightly from the normal mode, they are even a little bit worse. The same goes for the game part, where the smartphone stays at 41 fps. In fact, to discover the usefulness of this high-performance mode, you have to use the smartphone during a long game session. It would indeed seem that this mode slightly decreases the performance of the smartphone, but regulates the temperature of the device better, allowing it to maintain a bonframerate for longer and without overheating.

Preuve that the cooling works well, after one hour of intensive play, the smartphone does not exceed 33 °C.

Photo

La photo part of the Oppo Reno2 consists of the now classic trio wide-angle / ultra-wide-angle (UGA) / telephoto lens. For the wide-angle, the smartphone uses a 48 MP sensor (IMX586 from Sony) associated with an equivalent 26 mm 24x36 optic and opening at f/1.7. The UGA module benefits from an 8 MP sensor with a focal length of 18 mm opening at f/2.2. Finally, the telephoto lens is composed of a 13 MP sensor with a 58 mm lens opening at f/2.4. The last 2MP sensor is used to assist in portrait capture.

Quatre photo sensors are better than a ?

Tout like the Oppo Reno 10x Zoom, the Reno2 can "zoom in" (by combining digital and optical zoom) to reach a focal length of 83mm with the telephoto lens.

À Like many terminals with highly defined sensors, Reno2 uses aupixel binning to offer 12 MP images captured with a 48 MP sensor. This allows more light to be recovered and better photos to be taken, especially in low light conditions. We note in passing that the smartphone uses a more aggressive treatment of contrasts. And finally, if the 48 MP photo lacks a spike in the center, the colors are a little better respected with this mode.

By premium on board, the Oppo Reno2 shots are rather good. As mentioned above, the bininga pixel tends to overemphasize contrast, but the images are not unpleasant to look at. Compared to Pixel 3a, which still serves as a reference for "classic" focal lengths, the Reno2 does not fare too badly, even if Pixel 3a offers a more natural rendering of colors and contrasts. Also, due to a lower ISO rise, Pixel images are a little less clear.

By night, like many recently released smartphones, the Reno2 automatically "forces" the device into a night mode. The high ISO level combined with strong software processing allows for a fairly detailed image to be reproduced. However, the picture also takes a reddish tint, giving colors that are not very faithful, not to mention the rather pronounced noise. Notwithstanding the colors, Pixel 3a does not do as well, but it should be noted that, by default, it does not opt for its "night vision" mode. With this mode, the pictures of the Pixel almost seem to have been taken during the day, so much the software has been well optimized.

Lorsque we switch to the telephoto module, it is a bit the opposite of the normal module. Far from too much contrast, the smartphone offers a pronounced smoothing. On the other hand, the sharpness of theXiaomi Mi 9 is much better, even if its color reproduction is less accurate. This makes details stand out more and simply gives a better picture. At night, and this is a common problem for all smartphones with this type of module, the main sensor takes over and a digital zoom is then applied. But this doesn't go without a little software processing. Combined with a longer exposure time, the shots are a little better than what we usually see, but the overall quality is still quite approximate.

Grand classic photo on smartphone in 2019, the Reno2's wide-angle module could have been better optimized. Without being bad, it suffers from the same ills as the telephoto module. The colors are more faithful than those of the Mi 9, but the sharpness is not there. The lack of detail is such that the image appears almost blurred in places.

Quand the brightness comes to miss, an optimized night mode takes over again. And despite a rather closed optics and a poorly defined sensor, the Reno2 manages to output rather correct images. As with the main module, the colors are magenta, where the Mi 9's photos retain a more yellow hue, but are more in line with the colors of our scene at 3 lux. Overall, the better corrected Reno2 shots are much more detailed and usable. Note that the pause time is also longer (1/8 s vs 1/14 s) and therefore requires to be perfectly still to avoid blurred pictures.

Téléobjectif x2 vs hybrid zoom x5

Avec his Reno2, Oppo puts forward the 5x hybrid "zoom". Put on the test bench, this lens equivalent to 83 mm in 24x36 is not really up to our expectations. By digitally zooming 1.5 times, the result is not exceptional. The colors are little respected and the stitching is discreet. We then understand the price difference between the Reno2 and the Reno 10x, which offers a real optical 5x zoom.

Ultra Dark Mode 3 Lux vs 1 Lux

Enfin, the Reno2 is equipped with a "total" night mode (or "ultra dark mode" in VO). As its name suggests, it is an improved night mode which, according to Oppo, gives the best of itself between 1 and 3 lux (1 lux corresponds to the light of a candle at one meter in the dark). As you can see, at 3 lux (or the usual lighting of our night scene), thanks to a stronger ISO rise than in the default shot, the picture appears brighter. However, this is to the detriment of the details. At 1 lux, we can no longer rely on faithful colors or shapes, but we can be satisfied to distinguish the scene. Let's insist on the fact that the scene is really dark and that it appears only with the reinforcement of a huge increase in sensitivity (ISO 12 800), sensitivity that drowns the scene under the noise.

Mode portrait, front camera and vidéo

In portrait mode, while it is usual that the telephoto lens takes over, it is the main module that remains. The shots are rather well done and the cropping is quite natural, even if the blur around the hair is not always realistic.

For the video part, the smartphone is able to shoot up to 4K and 30 frames per second. It is possible to change the focal length during a recording and the autofocus tracking works easily.

Enfin, the selfies camera with a 16MP sensor and hidden in the retractable module - fast enough to use - does what it is asked to do. Like many Chinese terminals, the software smoothes faces a bit too much, giving faces a plastic look.

Autonomy

Oppo Reno2 draws its power from a 4,000 mAh battery. When we first tested it on our Aiming at Target test (simulating a daily and rather intensive use), the Chinese cell phone went offline after 17 h 41 min. A good score that allows it to get the 5th star and gives it, in theory, an autonomy of almost 2 days and a half in more moderate use.

Oppo has made fast charging one of its priorities. Thus, Reno2 is compatible with "Flash Charge VOOC 3.0". With the supplied 20 W power supply, it took 1 hour and 24 minutes to fully charge the device.
