The screen has a 1600×720 pixel resolution, which may not appeal everyone: Even some of the cheaper smartphones these days offer better resolution than that. We didn't really enjoy the colour reproduction, and thought the screen could have been better.
The Oppo A9 2020 comes with a 5,000 mAh battery that is good for almost two days on optimal usage. We played Call of Duty to Asphalt, besides using social media, and found the battery life impressive. The phone’s charging, though, is not swift; once drained of its juice, it took some time to charge fully.
We reviewed the 8GB RAM variant and it held itself in good stead for most tasks. You can have multiple apps running in the background and still play a heavy game. Switching between apps is smooth and there is hardly any lag anywhere.
