This will reduce the amount of processing power that the game needs, which will help to reduce lag and frame rate drops.

Here are some tips to play BGMI in low end mobiles:

1. Close other apps. When you're playing BGMI, make sure to close any other apps that you're not using. This will free up more RAM and CPU resources, which will help to improve performance.
2. Keep your device cool. Overheating can cause performance issues, so it's important to keep your device cool. If you're playing in a hot environment, try to find a cool place to sit or stand. You can also try using a cooling pad or fan.
3. Update your device. Make sure that your device is running the latest software. This will help to improve performance and fix any bugs that could be causing problems.
