Oppo Reno4 5G test: one smartversatile and durable mid-range phone

Not easy to find the Smartideal phone ... Especially since the expectations of each other are different. While others will swear by the quality of the screen, others will only focus on the photo ... So we tried to satisfy everyone with a versatile device. And for that, we turned to the Oppo Reno 4 5G. At the crossroads between the Reno4 Plus and the Z, taking it takes what is best in both: photo lens 48 Mpx, 8 GB of RAM, 128 GB of memory, AMOLED screen, fast charging… for just € 369.

Oppo Reno4 5G: Unboxing and getting started

Oppa was founded in 2001 and the brand launched in 2004. She began by creating MP3 and MP4 players then mobile phones in 2008. Their premier smartphone released in 2011 (Oppo Find) and the brand is present in France since 2018. IN 2019, it was fifth largest manufacturer in the world de Smartphones with 9 factories around the world (including 6 in China). They have also been present in the headset and earphone market since 2015. OPPO is part of the group BBK Electronics which also owns Realme, OnePlus and Vivo. The Reno range was released in 2019 in different price ranges with the top-end Reno 4 Pro and the entry-level Z.

Le Reno4 5G is delivered in a box of very good quality, thick and rigid, covered with a sleeve colored blue highlighting the name of the phone with a shadow play. The regulatory references are on the top of the case. the smartphone is well protected between layers of cellulose insert. You also find:

  • Warranty, start-up and safety guides,
  • A transparent silicone case which will protect your device while keeping it visible,
  • Un tool to open the SIM drawer.
  • A plasticized screen protector (already on the phone),
  • A pair ofUSB-C in-ear headphones. Indeed, the Reno4 has no Jack 3.5.
  • Un mains charger and usb-c cable : it will make you enjoy the Super VOOC 2.0 fast charge. It is a proprietary system, but that does not prevent being able to charge the smartphone with other chargers. Count on 65W, 8A in order to move from 0 to 60% in 15 minutes et 0 to 100% in 36 minutes! It is quite imposing because it is 5,5 x 3 x 5,5 cm (without the male plug) for more than 100 gram.

This fast charge is a real strong point of this product.

Let's take a closer look at the phone. Although it has a relatively standard shape and size, it is relatively well made, with good finishes and superb back cover. We tested the Galactic Blue version (there is a Space Black version). The color gradient from light blue to dark blue is very pretty, with a glitter effect. This part is also covered with Gorilla Glass 5. The 3 photo sensors are slightly prominent and we therefore advise you to use protection because in the event of a fall, they are the ones who risk hitting first. Ditto if you put it on a rough surface. He does 16 x 7,4 x 0,78 cm for 183 grams. It is therefore very fine, but will reach 1 cm taking into account the thickness of the sensors.

The deep black facade is in Gorilla Glass 3 + and has 2 photo sensors. The main of 32 MPX and the secondary (for depth) of 2 MPX. Fans of Selfies are going to be in heaven. The ratio of this 6,4 inch screen is 90,7% for a report of 20: 9.

The frame is made of polymer, therefore plastic. The whole is really successful and we have a very beautiful object.

On the lower edge of the phone, you will find the SIM holder drawer. Be careful when opening this drawer with the small punch, you have to press the hole on the left of the drawer (screen up) and not on the right, otherwise you will smash the microphone. the Reno4 5G is equipped with a dual nano SIM rack simple (one above and one below). No hybrid system. This means that memory is not expandable. You will also have the outputs of the external speaker on this slice.

OPPO has bet on the simplicity of the buttons because there are only 3:

  • On the left edge: the buttons of volume + and -.
  • On the right edge: the button On Off.

It is also possible toactivate your phone by lifting it and unlock it by facial recognition or fingerprint. Facial recognition works very well, with or without glasses and in acceptable light. The papillary recognition will be done by placing your finger on the bottom of the screen. Really practical and responsive, you can even come and modify the animations of the reading area to personalize your smartphone.

At the operating system level, OPPO has developed coloros, based on Android. You will have the right to version 11 for each. So you have the latest version of Red Velvet Cake! In use, the homemade overlay does not take precedence over the Android Stock but allows very simple customization such as putting Alexa by default voice assistant, change the animations but also do a lot more in terms of app management. We find ourselves very easily in the different parameters and ColorOS is really very nice. This OS is very reminiscent of RealmeUI, unless it's the other way around.

There is also a pretty nice little touch in the form of'a virtual button. You can guess its location on the right edge. Come pull this border to the left and you will have access to shortcuts, apps or folders. You can also change it.

Also note that if you buy other products from the brand such as the Oppo watch or headphones Oppo enco w51, they are recognized automatically and the installation is done with the fingers in the nose (which makes the papillary recognition work less well on the other hand).

When you use it for the first time, you will be asked for your Google credentials in order to automatically configure Gmail and other company applications. There are some applications preinstalled from OPPO and by Google but with 128 Go of memory, you will be able to please yourself.

In use, the phone does not suffer from latency. It is fluid, pleasant to use and its battery of 4020 mAh (2 x 2010 mAh) will allow you to last the day without any problem, even two days depending on your use. You can count on 390h standby (more than 16 days), 37h listening to music at 50% of the volume and 17 p.m. binge watching to become Fear The Walking Dead all at once! And in conversation? 26 h… That should do it, you sleep well every now and then don't you? Although we did not spend more than a day on the phone or binger, these values ​​were more or less confirmed.

It is also, as its name suggests, compatible with 5G, just deployed in France. But it is one of the few smartmid-range phones to be provided. Hence the fact that it is made to last. he is also NFC (Android Beam, HCE and UICC), Bluetooth 5.1 et Wi-Fi 5. Hey no, no Wi-Fi 6.

Technical specifications

  • Dimensions: 159,3 x 74 x 7.8 mm for 183 grams,
  • Screen: 20: 9, 6,4 ″
  • Robustness : Gorilla® Glass 3+ for the front, Gorilla® Glass 5 for the back
  • Water resistance: IP54. So don't be crazy.
  • Memory : 128 GB internally, 8 GB RAM. Not expandable.
  • SIM card : dual nano SIM
  • Operating system : Android 11 through ColorOS 11
  • Drums : 4020 mAh, USB C charging, 65W, 8A
  • Réseaux: 2G, 3G, 4G + and 5G (including the 2 bands authorized in France)
  • Connectivity: Wi-Fi 5 (2,4 and 5 GHz)
  • GPS: GPS / AGPS / Beidou / Glonass / Galileo (Figaro, maginifcoo…) / QZSS
  • Other: NFC,Bluetooth 5.1
  • Fingerprint sensor: Yes
  • Facial recognition: Yes

The technical characteristics of the Oppo Reno 4 5G are therefore quite standard when compared to other current mid-range phones, both for battery life and memory. What will differentiate it a bit is its super fast charging and 5G. It is a shame not to have expandable memory or Wi-Fi 6 (although this is more the prerogative of high-end).

Oppo Reno4 5G: sound quality

Of course, having a good sound is essential for a smartphone because it replaces your phonograph and your K7 player very effectively. Is the Reno4 5G is level? The answer is yes !

Note that it has no software processing preinstalled like some brands (Sony and its DSEE for example). You have the android audio player and the integrated equalizers, but also and above all those of your streaming applications. No home listening app either, because since most people only listen to streaming, we can understand that the brand does not waste time with home reading that will not serve.

The audio processing has been really polished by Oppo. It will thus be able to manage both lossy formats (lossy like MP3, AAC ...) and lossless ones (lossless) like FLAC, APE or WAV. It's great with wired headsets or headphones, but if you want to use wireless devices, you don't have to have a pickup treatment. Oppo does it right by allowing you to listen in Hi-Res Audio Wireless via Bluetooth thanks to codecs such as…

The rendering is excellent if you also use the suitable material (such as the excellent helmet Sony WH1000-XM4)… You will take a loud slap. The phone can take the Hi-Res audio to the height of 24 bits, 48 ​​KHz. Of course, it is necessary to have a streaming provider that allows you to have Ultra HD, which is not the case for all. On the other hand, if you have headphones of very good quality but functioning in Jack 3.5, this will not be possible because the new Oppo Reno4 5G does not have such a plug.

It also supports the Dolby Atmos, which is very interesting for videos… With headphones or earphones that go well, of course! Indeed, the Reno 4 5G is also equipped with a loud speaker " external " allowing sound to be broadcast through the lower edge of the phone. Even if it is not bad, it will not allow you an intensive immersion. For ambient noise, it does.

In communication, RAS, we have a completely standard and satisfactory sound even if there are a lot of variables.

Audio characteristics

  • High resolution : Yes. High-resolution audio and high-resolution wireless audio.
  • Codecs: AAC (basic lossless format successor to MP3) / APE (lossless format from WAVE) / FLAC (free lossless format, used for HD streaming, 2001) / AMR (rather dedicated to speech) / MID (or MIDI) / MP3 / OGG (free compression format) / WAV (Microsoft / IBM format) / WMA (Microsoft format)…
  • Bluetooth codecs: SBC (For lossy format), AAC (For lossy format), APTX, APTX HD (used for listening to HD music in Bluetooth without loss of quality), APTX TWS, LDAC (SONY format used for listening to HD music in Bluetooth without loss of quality)
  • Various: No 3,5mm audio jack but possibility via USB-C

Oppo Reno4 5G: gaming and video playback

The two being inseparable, we are dealing with these two subjects at the same time. They each require a good screen and clear, stable colors.

Concerning Gaming, the Oppo Reno4 5G is equipped with a GPU graphics card Adreno 620 allowing the use of RAM type LPDDR4X (Which is the case here). This graphics chip is included on the Snapdragon 765G SoC, from Qualcomm® of course. This processor is dedicated to mid-range devices and allows the integration of 5G, HDR, UHD, Wi-Fi 6… It is designed for Gaming because it supports Elite Gaming functions (hence the G). It has proven itself and that's a good point.

The Reno4 5G is also equipped with a screen AMOLED FHD + (2400 x 1080 px, 16,7 million colors) with a ratio of 20: 9. This is great for gaming because you will have a larger field of view, more detail, that 16: 9 screens don't have. It also has a 180Hz sample rate in game (135 in standard mode) which allows to have a very good recognition of touch gestures. It is an indisputable plus for FPS for example. However, where we lose a bit in logic is that Oppo clocked its screen at ... 60 Hz. And that, that's a shame, because competitors are now often at 90 or even 120 Hz.

This is felt with very greedy games like Call of Duty ou Asphalt 9. It's not that you're going to have micro freezes or problems of the kind but rather sensations of "jerks", of lack of fluidity due to too little refreshed screen. Nothing bad despite everything, but if you are looking for the excellence of pro gaming, this will get in your way, especially for first person shooters. Besides that, the loading times are quite satisfactory and the graphic rendering is excellent. Except in the extreme cases of these greedy games, you can play everything without any problem.

Regarding video playback, the advantages of gaming are valid. 60 Hz is not a problem here. The AMLOED panel allows a very good color management, of dark deep and colors present. The gradients are also very well managed (no halo or blur phenomenon). The contrast ratio is very good and the brightness, even if a little weaker than the competition with 430 nits on average (430 candles or candelas per m²), is quite satisfactory. The image is really very clear, the FHD + does wonders.

In terms of video and games, the Reno4 5G blows hot and cold. On the one hand, it has a very good SOC for the Gaming, an AMOLED screen, a good touch sampling frequency, excellent image quality… but besides that, the brand chose a timing at only 60 Hz and a little low brightness… But frankly, to watch a series or a movie in UHD streaming, you will be completely satisfied. Especially with Dolby Atmos sound!

Video specifications

  • Processor : Qualcomm® Snapdragon 765G octo-core 1,8, 2,2 and 2,4 GHz SoC with Adreno 620 GPU
  • High-resolution video: Yes. 2400 x 1080 FHD + screen.
  • frequency: 60Hz refresh rate, 135-180Hz touch sample rate

  • Supported video formats: avi / mp4 / 3gp / flv // wmv / asf / mov / mkv…

Oppo Reno4 5G: photo and video capture

With its 48 Mpx, the Reno4 5G is full of promise for all those who have traded their cameras for a smartphone. But let's be honest about one thing, you still have to avoid doing this with “budget” phones that will take nauseous photos of you.

As announced, Oppo has endowed its smartphone from 3 photographic sensors in back :

  • Un main sensor IMX586 from SONY of 48 MPX, 6 lenses, f / 1.7 aperture, 26mm focal length, 4-in-1 pixel technology and digital stabilization. For this type of photo, the image will be between 15 and 20 Mb. They are relatively sharp, precise and colored in optimal conditions. 48 Mpx photos are necessarily 4: 3.


  • Un 119MP 8 ° ultra wide-angle lens, 5 lenses, f / 2.2 aperture, 16mm focal length with digital stabilizer.
  • A captor Monochrome de 2 Mpx, 3 lenses, f / 2.4 aperture.

You can count on a digital zoom x 10. HDR is also taken into account, but it's now part of the norm. The system also has a "IA" which will detect the subject or the scene you are photographing in order to adapt the aperture and the parameters accordingly. But this way of doing things is more related to Android than to Oppo. No dedicated photo application but notable evolutions of Android functions. You will have the expert mode that we find on many current products where you will come to play with the ISO, the color of the whites, the brightness, the opening time ... The brand has however put forward Portrait, Night, Expert, HDR, burst, Ultra Stable Video (very good), Bokeh (blur in the background), text scanner ...

Photos are relatively sharp in optimal light conditions. The ultra wide-angle generates a slight distortion, but nothing bad.

The colors however tend to be a bit too much exacerbated for blues and greens. HDR is therefore not really necessary. This type of slightly frank colors is not bad and we find it quite regularly with the new sensors.

We very much enjoyed the Night mode which gives good results. Where he is really stunning, it is to photograph a starry sky. You have a sky which remains black and the luminous spots of the stars which stand out on the whole. The exposure time is relatively short, around 5 seconds. The software processing is excellent.

But paradoxically, in intermediate brightness, you will have less precise photos, with sometimes attenuated details, like an impression of brushstroke, bokeh on the main element. However, this remains quite limited and quite acceptable for “all-around” photos.

The weak point of the Reno4 5G is its zoom. Beyond x5 (or even x3), it is unusable. Take a look for yourself.

If you are a fan of selfies, you can take a picture with the dual 32 Mpx front sensor, Sony, F 2.4, 5 lenses and its sensor of 2M, F2.4, 3 lenses, dedicated to depth. Suffice to say that in 32 MPX, your beautiful smile will be unforgettable!

The results are generally relatively satisfactory with these fairly sharp and colorful photos, its powerful ultra-wide angle and its exciting night mode. The slightly exaggerated colors are not much of a problem, unlike the purely digital zoom which struggles to compare.

Photo features

  • Focus: Auto-Focus type PDAF, CDAF and LDAF.
  • Sensors: Digital stabilization EIS, HDR, fixed focus ...
  • Other: photo flash, lighting, HDR technology (high dynamic range), night mode, panorama ...
  • Zoom : digital x 10
  • Photo formats: JPEG

The video part is also very good and will benefit from the same strong points as the photo part: sharpness, color, AF, HDR… The colors are well restored and balanced. Thanks to digital stabilization, you can think of yourself as Spielberg! Of course, you will have the right to 4K at 30 fps, 1080p and 720p at 30 or 60 fps, a choice.

And for slow motion, let yourself be tempted between the 720p at 240 fps and 1080p at 120 fps ! A delight !

You also have the film function in the camera menu to switch to expert settings. Again, it is a real success. But take a look at our video to see what it's like.
