Battery Woes:

If the issue persists, consider replacing the battery or using a power-saving mode.

Slow Performance:

  • Problem: Your phone is lagging or freezing frequently.
  • Solution: Clearing cached data, uninstalling unused apps, and restarting your phone can often improve its performance. You can also try resetting your device to factory settings as a last resort, but make sure to back up your data first.

App Crashes:
