OPPO Reno4 Pro Review


Post Tags

With Reno series, OPPO tries to emphasise on couple of things — looks and camera. The latest Reno4 Pro is all about the looks, cameras and of course the display.  The OPPO Reno4 Pro comes with quad-camera setup, Snapdragon 720G mobile platform, 65W Super Flash Charge fast charging that can charge the phone fully in 36 minutes. We got hold of the device for few days and here’s what we think about it.

Why should you consider buying?

Lightweight build

OPPO has long been a leader in designing attractive smartphones, so the Reno3 Pro is in no way, different. The Reno4 Pro Indian variant is a 4G device from OPPO which is not to be confused with the 5G version released in China. As per the company claims, the Reno4 Pro is lightest of all Reno devices. Thanks to all-plastic build. It weighs at 161 grams and measures 7.7mm thickness, which is just right for a comfortable handgrip. On the rear, we have an anti-glare matte finish panel that doesn’t attract fingerprint. Even though it’s light and sturdy, it lacks the much-needed premium-ness factor at this price point. The real estate near the camera module gets a plastic treatment that’s prone to smudges and fingerprints. Near the symmetric camera layout, we spotted “Innovative Quadcam” mentioned on it. Really?

Coming to the button placement, we have a power button that doubles up as the Google Assistant button. A small green strike on the power button brings a kind of cool factor to it as well. Feedback from the buttons is neat. The bottom part of the device houses 3.5mm audio jack, USB Type-C port, and a speaker grille. That’s pretty much what you would need to know about this smartphone when it comes to design.


The Reno4 Pro sports 6.55-inch (2400×1080 pixels) Full HD+ AMOLED curved display with Corning Gorilla Glass 5 protection. It also supports the 90Hz refresh rate and 180Hz touch sampling rate. Saying that the company has dropped the HDR10 support for the Indian variant. At this price point, the display is great.

With great contrast, colours and a very fitting 20:9 aspect ratio, there is not much to complain about. The sunlight readability is great too, thanks to 1100 nits peak brightness. Just like other phones, it is possible to lock it to either 60hz or 90hz. On the top left, we have a single punch hole this time housing a 32MP camera for selfies. So, how distractive is the punch hole? My answer is, you will get used to it. Since it is on the left, it didn’t come in the way of me watching multimedia content. Overall, the Reno4 Pro display is top-notch.


The Reno4 Pro is powered by the latest Octa-Core Snapdragon 720G 8nm Mobile Platform (Dual 2.3GHz Kryo 465 A76 + Hexa 1.8GHz Kryo 465 A55 CPUs) with Adreno 618 GPU under the hood. OPPO’s decision to go with this chipset at this price point is a bit confusing. It’s not that the chipset is lacking but we expect a bit more, again at this price.

Nonetheless, in our usage, we experienced zero lag, zero hitches, and it performed like a champ, consistently. The key here is consistency and of course, due to the nature of the chipset, there are no heating issues even when playing games or using the camera. We tried Asphalt 9, Shadow fight 3, PUBG, and other small games.

Check out some synthetic benchmark scores below.


In recent times, ColorOS has just become one of the best custom skins on top of Android. After all, simply, the software makes or breaks the experience on a smartphone. It is highly recommended that a no-frills experience awaits you on a smartphone and that’s what the OPPO Reno4 Pro delivers. The UI and the Snapdragon 720G flow so well on the Reno4 Pro, it is seamless. It must be the optimisation in terms of performance, but it is also heavily optimised for battery life.

The ColorOS 7.2 offers lots of customisation options right from the icon packs to gestures to themes and more. You also get a game space option that lets you set custom profiles for games. On the downside, the phone has a whole lot of apps on board, some can be removed, some cannot.

Battery life

The Reno4 Pro is powered by a 4000mAh battery with 65W Super Flash Charge (SuperVOOC 2.0) fast charging technology that can charge the phone up to 50% in 14 minutes and 100% in 36 minutes. Battery life was solid in my usage, with 20 to 25% charge left at the end of the day. Well, with SuperVOOC 2.0, what else would you expect. It achieved a One Charge Rating of 18 hours and 13 minutes, which is good for a phone with a 4000mAh battery.

Why should you avoid buying?


The Reno4 Pro comes with a quad-camera setup

  • Primary camera: 48MP with Sony IMX586 sensor, f/1.7 aperture, EIS
  • Secondary camera: 8MP ultra-wide camera with f/2.2 aperture
  • Third camera: 2MP macro camera
  • Fourth camera: 2MP mono camera with f/2.4 aperture
  • Videos: 4K 30fps, 1080p 60fps, 720p 60fps
  • Front camera: 32MP with Sony IMX616 sensor, f/2.4 aperture

This is the department where OPPO needs to concentrate more on. The camera app looks and functions remain similar to other OPPO devices. Also, switching between cameras and other modes is easy too. Getting into macro mode is kind of odd here since you have to go to pro mode and select the option. Coming to the quality, the primary camera captures some very good photos with fine details. Most of the time, pictures churned out from the main sensors were sharp, had good colors and accurate exposure. Dazzle mode helps you to get more saturation, if in case.

The wide-angle camera also did a good job concerning colors and HDR. However, we had white-balance and color shift issues on both primary and wide-angle cameras. Portrait mode works well with good edge detection, misses at times though. The macro sensor under daylight condition works decently, but often looks washed out. Under low-light conditions, the Reno4 Pro produces an average output with enough light around.
