Review Oppo Reno8 5G: smartphone for people who value design, camera and fast charging 

Oppo Reno8 5G continues Oppo's familiar strategy when emphasizing on youthful design, catching trends with a camera system that meets a variety of needs, agile enough performance and especially impressive battery charging speed.

The design is square, more trending

Right from the design, Reno8 5G has brought a completely new back, different from the previous Reno7 5G. The back and bezel of the Reno8 5G are squared, more trending than the rounded style of the previous generation. Reno8 5G also marks the first time that the Reno Series has applied the "volcano" rear camera cluster design, emerging from the back, inherited from the Oppo Find X3 and Find X5 series.

The rear camera cluster is beveled seamlessly with the back, creating a fancy and preventing dust from sticking around the camera area. The device has two versions in yellow and black, both applying Oppo's signature Oppo Glow finishing technique, creating fancy gradient effects and effectively supporting anti-fingerprint and sweat stains.

Despite having a square design, at the edges, Oppo still makes beveled lines so that holding the Reno8 5G does not need to be in the hand. The device is quite thin and light with a thickness of only 7.67mm and a weight of 179g.

It is noteworthy that the Oppo Reno8 5G is equipped with IP54 light water resistance, so you can rest assured if you use the device in drizzle or when it gets wet.

The point that I find most regrettable about the design of the Reno8 5G is that the back and chassis are all made of plastic, so it has not created a cool, high-end feeling like machines using metal frames and glass backs. This is the point I think Oppo needs to improve because Reno8 5G is now in the high-end segment.

The screen is bright and clear, but there is still no 120Hz refresh rate, the chin is still thick

On the front, Reno8 5G still has a 6.4-inch AMOLED screen with 90Hz refresh rate, Full HD + resolution of 1080 x 2400 pixels, 20: 9 aspect ratio. This screen has an average brightness of 430 nits, and can increase brightness to 600 nits when adjusted manually, up to 800 nits if left automatically and used outdoors.

In fact, when I use it in the hot sun, the screen of Reno8 5G displays well, clearly, with little glare. The device can also watch HDR videos on YouTube with good quality, bright and fresh. These screen parameters are completely similar to the Reno7 5G. Another unfortunate point when Oppo has not yet upgraded to 120Hz refresh rate and the chin or bottom edge of the screen of Reno8 5G is still thick and looks unbalanced. At the same time, the machine also only has single speakers instead of dual speakers.

Similar to previous Reno generations, Reno8 5G still uses in-screen fingerprints with fast and accurate recognition speed.

Both front and rear cameras use Sony sensors, image quality is stable

Besides the design change, the rear camera cluster of Reno8 5G has also been upgraded with a Sony IMX766 sensor for the main camera, similar to the sensor on the camera of the Find X5 Pro and Reno7 Pro. Sony IMX766 sensor has 50MP resolution with large 1/1.56-inch size and 1.0um large pixel size, which can be increased to 2.0um after 4-pixel stitching, allowing more light to be captured, improved low light image quality. The other two cameras of Reno8 5G are still at a basic level with an 8MP ultra-wide-angle camera and a 2MP macro camera.

The 32MP selfie camera on the front is also significantly upgraded with a Sony IMX709 sensor. This is the sensor used on the Reno7 Pro. According to Oppo, the Sony IMX709 sensor is specifically designed by Oppo and is an RGBW sensor, which increases light capture by 60% and improves noise reduction by 35% compared to traditional RGGB sensors, producing photos. Selfies are clearer in low light or backlit environments.

In addition to hardware upgrades, Oppo Reno8 5G also adds shooting and portrait shooting features thanks to AI algorithms such as night video automatically activated when shooting at night, improving image quality, color sharpness and detail are displayed, resulting in brighter and clearer movies; HDR video algorithm turns on automatically in backlit conditions, limiting overexposure and highlighting shadow details; Night portrait algorithm uses Turbo RAW algorithm to process AI noise reduction in RAW format, resulting in sharper and more realistic portrait images.

Oppo Reno8 5G also has other useful features to increase overall image quality such as: AI portrait correction that intelligently and naturally beauts the subject's face, Portrait Mode, Time-lapse video Time and Slow Motion 960fps AI helps users create their own style portraits. 

Fast performance, good game play with Dimensity 1300 . chip

In terms of configuration, Oppo Reno8 5G is the first smartphone in Vietnam market equipped with MediaTek Dimensity 1300 processor that supports 5G connectivity. This is an upgrade compared to the previous generation Dimensity 1200-MAX equipped on the Reno7 Pro 5G.

Oppo Reno8 5G test performance
Dimensity 1300 is manufactured on the 6nm process, with 8 cores with a maximum processing speed of 3Ghz, integrated with HyperEngine 5.0 technology to improve gaming experience, upgraded MediaTek Imagiq image processor for good image quality. better in low light.

Reno8 5G still has 8GB and 256GB of RAM memory capacity, comes with RAM expansion technology to add 5GB of virtual RAM.

Reno8 5G is also equipped with a heat dissipation system with a cooling area that is 16.8% larger than the previous generation, including a graphene film and a large vapor chamber. I tried to force CPU Dimensity 1300 on a machine running at 100% capacity for 1 hour using CPU Throttling Test software, after 30 minutes, the device still retains 75% of the performance and after 1 hour, the performance still reaches 69%. , impressively. 

Meanwhile, when I ran 5 times in a row with AnTuTu software that specializes in evaluating the overall performance of the system, the Oppo Reno8 5G's score was only reduced by 7%.

Continued is the GPU score but measured in 3D Mark. I also quickly tested the stability when having to continuously load with the Wild Life Stress Test, and found that the stability of Reno8 5G was very high, reaching 98.3%%.
The device comes pre-installed with ColorOS 12.1 operating system based on Android 12 with some outstanding features such as non-touch gestures that allow you to perform some simple operations such as scrolling pages, answering calls, stopping video playback without touching. to the screen; Features Multi-Screen Connect allows users to seamlessly switch and sync between phone and computer, Secure Recent Tasks, Require Password on Power Off, and Notification Anti-Theft.
In the past 3-4 years, ColorOS has shown stability, smoothness, good optimization, diverse customization capabilities, proved to be slightly better than Samsung's OneUI or Xiaomi's MIUI.

The battery is enough for all day use with charging intensity, 80W charging in just over 30 minutes is full
Reno8 5G still uses the same 4,500mAh battery as the previous generation, but has been upgraded to SUPERVOOC 80W fast charging, allowing to charge 50% of the battery in just 11 minutes, 100% of the battery in just 28 minutes. The 4,500 mAh battery seems a bit lower than the current standard 5,000 mAh on most smartphones, but with the screen and moderate refresh rate, the MediaTek Dimensity 1300 chip works cool, I can completely use it. comfortable use all day.
About the charging speed, I tried charging from 0%, turned on the device and the Always On Display screen, and found that 11 minutes of the device was full of 45% battery, and 33 minutes was full of 100%. I tried a few more times and found that the 100% charging speed is still only fluctuating compared to 33 minutes for about 1-2 minutes, and the charging speed for 11 minutes is still about 45-48%. Perhaps because my room is not very cool, usually around 28-29 degrees Celsius and I have the AOD screen on, so the charging speed is not as fast as the company announced.

Even so, this is still a very comfortable charging speed, and I never need to charge the Reno8 5G overnight again. In the morning, brushing teeth, washing face, changing clothes, personal hygiene is a fully charged battery, enough for a whole day of use.

To ensure device safety, Reno8 5G also has a 5-layer charging protection and battery life protection algorithm that, according to Oppo, can extend battery life up to 1600 charge and discharge cycles, equivalent to about four years of average use.


Oppo Reno8 5G has shown that Oppo has a good reason to increase the price when significantly upgrading the design with a more eye-catching square design, the "volcano" camera cluster also creates a fancy and unique look. Camera quality is also very stable with a large 50MP sensor from Sony, image quality in most lighting conditions is good, can be used to share immediately on social networks without any further editing. Configured with MediaTek Dimensity 1300 chip, it gives fast performance, smooth handling of heavy games, and cool running.
