The phone stutters when playing games. What can I do?

Please try the below:

1. Connect to a stable network and try again.
2. Clear all background apps to ensure the phone has enough random access memory.
3. Downgrade the game configuration (image quality, resolution, turn-off special effects) and try again.
4. Ensure your phone is fully charged. The power-saving mode will affect the performance. If the power-saving mode is turned on, turn it off temporarily.
5. Restart the phone, open the game, ensure there is enough random access memory and try again.
6. Enter the application management to clear the cache and try again. (The game data will be lost after clearing; back it up before clearing.)
7. If the phone has just been updated, restart it and try again.
8. Check whether the game and phone system are updated to the latest version.
