Oppo Reno 4 Pro 5G review: DO NOT call it mid-range

We live in strange times for the world of mobile telephony. Times in which the second smartphone manufacturer in the old continent was forced to leave the place at the top of the category, and times in which companies such as OnePlus and (above all) Oppo become increasingly important and well-known also in Italy, and are increasingly working on different market slices and the creation of ecosystems composed not only of smartphones, but also of wearable devices.

And Oppo, with his Reno 4 Pro 5G and the whole new Reno 4 series, has once again shown that it believes more and more in the Western world, underlining the importance of the mid-range of the market, in which we now see more and more devices with characteristics much closer to the top of the range, which to cheap smartphones. Although, to be honest, it is not that the price of the Oppo Reno 4 Pro 5G is then who knows how cheap.

Oppo Reno 4 Pro review: don't call it mid-range

Package Contents

Details relating to the quality of products of Oppo can be seen from the packaging of the device. On the front of the box there is a background image with which you can see the word "Reno", on which the smartphone series is superimposed. Inside the box there are:

  • OPPO Reno 4 Pro 5G;
  • wired earphones with USB Type-C port;
  • USB / USB Type-C cable;
  • Super VOOC power supply;
  • plastic film pre-applied on the screen;
  • pin for the SIM slot;
  • soft cover in transparent TPU;
  • brief instruction manual, also in Italian.

Design and materials

L'Oppo Reno 4 Pro 5G it features a sleek design and premium feel that clashes a bit with its mid-range definition. At the front there is a curved display protected by a Gorilla Glass 6, while the back cover of the sample we received for testing is of the color Galactic Blue and is made with a very particular finish, which the company calls Crystal Diamond, which makes it all in all elegant and which is less ready to retain fingerprints. Weighs 172 grams and its dimensions of 159.6 x 72.5 x 7.6 mm, make it very pleasant to use.

There is no notch at the front: the camera has been inserted into a punch hole positioned in the upper left corner of the curved display, and the high and thin profile makes it very comfortable to use even with one hand. The power button can be reached with the thumb without much effort, while the volume rockers are positioned on the opposite side, but are slightly higher. The fingerprint sensor was placed under the screen.

The upper part and the lower part are flat, at the top there are two bands for the antennas, then below there is the trolley for the nanoSIM, the USB-C port and the speaker. And no, no headphone jack or the ability to expand memory via microSD.

At the rear there is the module for three integrated cameras, which is characterized by a camera bump with mirror effect which, in addition to being perhaps a little too protruding, is made of a material capable of guaranteeing a decidedly captivating visual effect, but which on the other hand tends to attract too much dust and various footprints.


The screen ofOppo Reno 4 Pro 5G is a panel AMOLED from 6.5 inches with a 20: 9 ratio and able to guarantee a FullHD + resolution. And all things considered it is a panel characterized by a pixel per inch density of 402 ppi: basically the same that we have already seen in the new OnePlus 8T. At the first start, contrast and saturation are set to settings perhaps a little too high but, fortunately, you can change this setting in the options related to the screen.

Here are the technical characteristics of the display:

  • Size: 6.5 ″ (diagonal)
  • Screen to surface ratio: 92.1%
  • Resolution: 2400 × 1080
  • Refresh Rate: up to 90Hz
  • Touch sample rate: up to 180Hz (five fingers)
  • Color Gamut: Vivid Mode 100% DCI-P3,135.65% sRGB / Gentle Mode 73.72% DCI-P3,100% sRGB
  • Pixel density: 402 PPI
  • Contrast: 5.000.000: 1 (typical)
  • Brightness: 500nits (typical), 800 nits (maximum in light), 1100 nits (peak)
  • Panel: AMOLED

But, except for this small detail, the screen of theOppo Reno 4 Pro 5G it is vibrant, has very deep blacks and very vivid colors and, among other things, it has more than enough viewing angles: a detail that is not exactly obvious, given the nature of the panel. However, this is not the sharpest screen we have had the opportunity to try lately, even if its prominent brightness is very high and it will almost never be necessary to increase the brightness to maximum: readability is excellent, even in direct light conditions, with medium settings.

La maximum refresh rate is 90 Hz, and it is possible to set 60 Hz if you want to save battery. But in any case, the visual experience of the panel is very satisfying, with fluid images and of good quality.

Camera - Oppo Reno 4 Pro 5G

The camera compartment of theOppo Reno 4 Pro 5G consists of three cameras. The main one uses a sensor Sony IMX586 to 48 megapixel, and is flanked by a 12 megapixel ultra-wide angle (with which you can also record videos using the Night mode) and one 3 megapixel 13X optical zoom, able to guarantee a hybrid magnification factor of 5x and a maximum digital zoom of 20x. Then there is a fourth sensor for laser detection autofocus.

As for photographic quality, images shot with Oppo Reno 4 Pro 5G they are all in all good. The dynamic range of the main camera is always more than enough, and things change little in low light. It is also possible to shoot at full resolution of 48 megapixels, but by default images are saved at 12 megapixels with pixel binning technology, which is quite common in most smartphones of 2020.

I am rather perplexed about the artificial intelligence algorithms with which theOppo Reno 4 Pro 5G recognizes scenes and optimizes shooting settings, which could modify images to the point of making them unnatural both in terms of color and contrast. However, it is true that it is most likely a characteristic of the company's algorithms, because it is a "problem" (if we want to call it that) that we also found in the Oppo Reno 3 Pro. In any case, HDR it works fine.

However, when using the ultra-wide angle lens, the photographic quality decreases, and all in all it is normal for this to happen. It may happen that you take pictures cwith less details and less vivid colors, so my advice is to use this lens only when shooting landscapes: a condition in which HDR does an excellent job even with the secondary lens.

Without praise and without infamy the optical zoom, which at 2X does an excellent job, but that the more you increase the magnification factor, the more noise and pastel colors become. I would advise against using it with magnification factors higher than 5X, because the artifacts start to become very visible.

Good videos, which can be recorded at maximum resolution 4K to 30 fps, and which can also be recorded in HDR, or ultra-stabilized with the mode Ultra Steady: in this case the quality is slightly reduced and the ultra-wide angle lens is used, but in good light conditions the results are more than good.

The videos made with the are also good new night mode. Of course, the quality continues to suffer from low light, but with careful handling of the movements you can get very interesting results, and you will be able to record videos with lighting conditions that would put almost any smartphone on the market in crisis.

La front camera is a 32 megapixel camera rather similar to what we have already seen on the OnePlus Nord, and is able to take selfies with good quality in well-lit environments, but it starts to have problems in low light conditions.

Hardware and Performance

To animate theOppo Reno 4 Pro 5G one thinks about it Qualcomm Snapdragon 765G, flanked by 12 GB of RAM memory of type LPDDR4x, a Adreno 620 e 256 GB of internal memory not expandable. All in all it is a respectable hardware, able to quickly start applications, manage multitasking without a hitch and to play games like CoD Mobile or Genshin Impact without too many compromises: on the other hand, in this case, the 90 Hz refresh rate of the screen also plays a lot.

As for the benchmarks, the results of our tests are in line with the vast majority of devices using the Snap 765G, but they are lower than those obtained with the OnePlus 8T, sold at a similar price but animated by one. Snap 865. Anyway, let's be clear: benchmarks aren't everything.

Good cellular signal quality, excellent reception to WiFi networks: in this case theOppo Reno 4 Pro 5G he managed to stay connected to the wireless home network even in areas where other devices were starting to trudge.


Oppo Reno 4 Pro 5G is animated by the Color OS 7.2, Based on Android 10. And without going around it: I'm not a big fan of Color OS, but I must admit that the user experience is more than cured and simple. All in all, this is the same software we have seen in Oppo Reno 3 or Oppo FindX 2, but with a couple of new features, such as a new mode of use with one hand, which compresses all the icons in the lower area of ​​the panel (and optimizes use with one hand), or the pop-up sidebar in which you can insert customizable shortcuts to applications or features .

The Always-On Display is present, and it is Dolby Atmos supported and - combined with the stereo sound of the speakers - makes theOppo Reno 4 Pro 5G great for both gaming and streaming TV series or movies.

In short, it is about a nice user interface, which allows scrolling and the use of the fast and responsive GUI, but which continues to be characterized by a sort of "rigid fluidity", which in my opinion is less refined than what we have seen - for example - in Samsung's One UI or OnePlus' Oxygen OS 11.


In the average the battery from 4000 mAh integrated into theOppo Reno 4 Pro 5G and that manages to guarantee a day of autonomy even with rather intense use. From our tests, we have found that the factors that most affect battery life are the brightness and refresh rate of the screen and the execution of games and, keeping the two under control, it could achieve much higher performance.

In any case, the real battery life does not matter: the new recharge 2.0W SuperVOOC 65 is able to recharge the battery from 0 to 50% i just over eleven minutes, which becomes 30 for a full charge. And this is an exceptional achievement. Unfortunately, it is not compatible with any wireless charging technology.

Price and conclusions - Oppo Reno Pro 5G

The selling price ofOppo Reno 4 Pro 5G is 799 euros, and is available in Galactic Blue and Space Black. And yes, it is an excellent quality device, but sold at a price perhaps a bit high above all considering the competition in the same market range, very fierce in terms of performance and with an excellent quality / price ratio.

It is however a well balanced device, which lacks little and nothing and which is made with an increasingly optimized construction process. On the other hand just think of the Find X2 Neo which, at the time of launch, was very expensive but which today has one street price more than adequate. Here, the same discourse must apply to theOppo Reno 4 Pro 5G: when the street price drops by a few tens of euros, it could be considered a best-buy.
