No one will suggest these : > Do this for all one time use apps (banking, youtube etc) : force stop, go to storage - clear cache (not clear data), remove the app from the recent apps list)
> Uninstall the unnecessary apps. Always keep the rarely using apps in the force stopped mode
> Long press the location icon. Go to location services, disable Wifi and bluetooth scanning
> Disable auto brightness always. Manually adjust or get used to use the phone under manual brightness when outside. No need to use extra dim.
