Oppo Reno2 Z: Review, price and specification – Smartphone

[ad_1]

Oppo tries to occupy the field by releasing a new mid-range smartphone, but with premium finishes. Reno2 lightweight version, the Oppo Reno2 Z is no less a smartphone with some strengths to argue. Launched under the symbolic bar of € 350, it is part of a sector where competition is fierce. Thus, it is found in front of the Xiaomi Mi 9T or Google Pixel 3a, fearsome in photo. Also, we can oppose a Honor View 20. And if finally his worst enemy was not just the Reno Z?

Oppo has made the "full" smartphone screen its trademark. The firm has thus made specialist slab devoid of notch or punch. The Oppo Reno2 Z is a mobile with exemplary finishes, whose large screen of 6.55 inches occupies more than 86% of the front panel. Only a thicker black border at the bottom of the terminal denotes. The selfie module is thus hidden, not in a retractable fin, as is usually the case on Oppo mobiles, but in a small square "pop-up".

In hand, the smartphone, although a little heavy (nearly 200 g), offers a high-end feeling, all in glass. The buttons fall well under the fingers and the unlocking of the device by a fingerprint sensor placed under the screen is reactive. On the back of the device, the color effects are quite successful and we find the small steel ball, another fool Oppo. It is used to collect shocks instead of the four photo sensor module.

To complete this overview, remember that the terminal has 128 GB of storage, of which a hundred hundred actually available. It is capable of hosting two nanoSIM cards or a single SIM card and a microSD card. The only flaw on the board is the lack of waterproof certification due to the retractable camera.

audio

The 3.5 mm mini-jack is positioned on the lower edge of the Reno2 Z, and it offers good results. Its distortion is fairly contained, crosstalk allows good stereo playback, while the dynamic range is quite wide. Finally, we can not say that the catch lacks power, nevertheless, we hoped better. A helmet a little too energy-consuming will not give any measure with this connection.

For external sounds, the only speaker is quite correct, but, as often, we must avoid pushing it fully under penalty of see saturate.

With the Reno2 Z, Oppo still chooses an "integral" screen. The 6.55-inch Amoled slab covers almost the entire front surface of the mobile. Covered with Gorilla Glass 5, the screen has a resolution of 2,340 x 1,080 px (394 dpi resolution). When we started our measurements, the default optimization soon showed deficiencies. Indeed, the screen was too bluish tint, and the measured color temperature confirmed this feeling by displaying more than 7,500 K, far from the expected 6,500 K. By setting the temperature to "warm" in the display settings, we got 6,686 K, which is a very good level.

Regarding the colorimetry, our probe has found a delta E at 4.1, beyond the threshold of 3 – under which the human eye can not perceive the drifts. In particular, the fluorescent green, turquoise and yellow hues are the most unusual. Nevertheless, it is noticeable and the display is quite natural.

While the Reno2 offered a maximum brightness of 737 cd / m², the Reno2 Z is only 438 cd / m². However, this brightness, associated with a contained reflectance, and an almost infinite contrast ratio (thank you Oled), does not pose a problem for use in full sun. At night, the minimum brightness was measured at 2.1 cd / m², which does not burn the retinas. Finally, the tactile delay measured at 73 ms is the average of the latest smartphones of the brand and allows the display to remain fluid.

Under the hood of the device, Oppo has renewed the Mediatek SoC Helio P90, already present on the Reno Z. However, the teams of the Chinese firm have decided to double the RAM that now goes to 8 GB. this does not translate into a massive gain in power. In our multitasking Review, the Reno2 Z even makes a (very small) little worse than its predecessor, with 93.25 points against 93.50. Otherwise, this score is more than honorable and the Reno2 Z will have no problem with everyday actions.

In the game Review, it is much more difficult, with an index of 25.45, and less than 15 fps on average. We can not then say that this mobile is made to play. The titles in 2D should work more or less fluently, but more greedy games will struggle to remain playable, even lowering some effects.

We are at the end of 2019, and a smartphone must therefore have more than three photo sensors. For his Reno2 Z, Oppo has installed no less than four. The Chinese manufacturer extends the 48 megapixel Sony IMX sensor and optics opening at f / 1.7 (26 mm equivalent in 24×36), as the main module. It is supported by an 8-megapixel sensor, with an ultra wide-angle lens (equivalent to 18 mm). Finally, the terminal has the services of two 2 megapixel sensors, both with an objective opening at f / 2.4. They are used to optimize the taking of portraits and add two filters.

By default, the Reno2 Z releases 12 megapixel shots using the binning pixel to merge 4 pixels into one. Comparing with an image shot at 48 megapixels, by day the differences are not obvious. The two images are very similar, the photo at 48 megapixels appears a little more contrasted and the details are more accentuated. Similarly, optical distortions are better handled when recording in maximum definition

Normally, it is in low light that the binning pixel makes sense. Here, it is clear that the gap is not obvious. We can just notice that the photo taken at 12 megapixels is a little smoother and therefore limits the noise.

Main module: 12 Mpx, f / 1.7, eq. 26 mm

For the main module, we wanted to oppose the Reno2 Z Google Pixel 3a, given their similarity tariff. By day, the clichés of the Oppo are of good quality, but the overall rendering is a little too hot and the optical deformations quite marked on the periphery of the image. For its part, the Pixel 3a exposes the scene a little better, the colors are more accurately reproduced and optical aberrations are better controlled.

When the light runs out, it's another round easily won by the American smartphone. While offering a much more limited ISO upgrade, Pixel 3a offers more natural colors, fairer exposure and smoother smoothness. Indeed, the photos of the Oppo tend to "drool", and shoot too much red.

Wide-angle module: 8 Mpx, f / 2,2, eq. 18 mm

The UGA module is now classic, but some manufacturers have trouble controlling it. Here, by offering a low definition sensor (8 against 16 megapixels for the Xiaomi Mi 9), and a limited software work, Oppo does not endow its Reno2 Z with the best possible quality. The picture lacks sharpness and seems almost blurry, optical aberrations are very pronounced and colors not very faithful. The contrast is total with the Mi 9, which offers a much more correct image.

By less brightness, the UGA module of Reno2 Z reproduces a little exploitable image, colors are poorly rendered, shapes and details are not at the rendezvous. The shot of Mi 9 is not exceptional, but still thanks to its better definition and more effective processing, the image remains acceptable.

zoom x2 facing the zoom x5

In the photo application, the Oppo Reno2 Z encourages to use a zoom x2, then x5. This intrigued us since this terminal does not have a telephoto module. It is simply a digital zoom made by reframing in the image. However, no software processing is applied (or so at least), and as you can see, at x2 and even more at x5, the result is not really usable, unless you like the "pixel art".

Portrait mode, front camera and video

The portrait mode is not forgotten on the Reno2 Z. With two additional sensors (2 megapixels each) to improve shooting. The subject is well cut and the blur applied can be natural if you do not zoom too much in the hair. For selfies, we are quite satisfied with the image processing done by the 16 megapixel sensor. By default, the smoothing is very discreet and the subjects do not appear too glossy. Finally, the Oppo Reno2 Z is capable of shooting up to 4K, but only at 30 fps. The 60 i / s is reserved for 1080p. Autofocus is quite responsive, the transitions are pretty smooth, and stabilization does a good job.

To ensure the power supply of its smartphone, Oppo uses a battery with a capacity of 4000 mAh. During our SmartViser autonomy Review (simulating a daily and rather intensive use), the device turned off after 22 h 59 min. A very good score that gives it autonomy theory superior to 3 days. Which is always appreciable.

Regarding the time of reloading, we are a little disappointed. Indeed, the phone is compatible with the health home fast charge, "VOOC 3.0". With the provided block, just over 2 hours were needed to reload the Oppo Reno2 Z to 100%. We were entitled to expect better.

Strong points

• Screen pretty well calibrated.

• Good ergonomics.

• Color in progress.

• Excellent autonomy.

Weak points

• Photo shutter very average, especially in low light.

• Limited performance at stake

• No seal certification.

For his new model, Oppo tried to copy the Reno2 recipe, with less success. Admittedly, the smartphone is very beautiful and well finished, but its poor performance in game and its very average photo module come black the table. The mobile is still quite successful. However, for more versatility, we will turn to the Xiaomi Mi 9T and for those who are satisfied with a single photo sensor (but oh how powerful), the Pixel 3a will be a good companion. Finally, apart from a more premium look, it's not much more innovative than Reno Z.
