For Gaming: You can play PUBG Mobile, Free Fire, and COD Mobile on low to medium settings at 30-40 FPS. Don’t expect 60 FPS or smooth gameplay on HD graphics. The phone will heat up after 30-40 minutes of continuous gaming. Vivo Y21 has a slight advantage because it is 10g lighter, so it feels better during long gaming sessions. Oppo A54 has better heat management due to slightly bigger body.
If you are a serious gamer, neither phone is ideal. But for casual gaming, both are okay.
Camera Comparison
The Oppo A54 has an advantage on paper when it comes to the camera setup.
The Oppo A54 features a 13MP main camera with 2MP macro and 2MP depth cameras, along with a 16MP front camera. The higher-resolution front camera gives the Oppo A54 an advantage for selfies and video calls based on specifications.
The Vivo Y21 comes with a 13MP main camera + 2MP macro camera and an 8MP front camera. On paper, its front camera has a lower resolution than the Oppo A54.
Overall, Oppo A54 is the better choice for camera specifications, especially if you prioritize selfie camera resolution and a more versatile rear camera setup. However, actual photo quality can vary depending on lighting, software processing, and shooting conditions.

Overall: There is no clear winner in battery capacity and charging. Both offer a 5000mAh battery with 18W charging.
Software and User Experience
The Oppo A54 runs ColorOS 7.2 based on Android 10, while the Vivo Y21 runs Funtouch OS 11.1 based on Android 11.
The Oppo A54 offers the ColorOS interface with various everyday features, while the Vivo Y21 includes features such as 1GB Extended RAM, which uses part of the phone’s storage as virtual RAM.
Both phones use older Android versions, so users should not expect the latest Android features or long-term software support.
Overall: If you prefer ColorOS, the Oppo A54 is a good choice. If you want Android 11 and Extended RAM, the Vivo Y21 has an advantage.
