    approx 1 year & 6 months...

    it's not about battery health...

    when i was in android 10 beta it was perfect...

    but beta 2 had some serious audio issue so I switched back to android 9....

    & boom....battery backup got down to 4 hr from full 8 hr+ in just 5 hr difference....

  • Hi Munim

    Thank you for your asking. Please try to enter "Safe Mode". If the function works well in Safe Mode yet the issue remains out of Safe Mode, please check on any disturbance from the installed 3rd party apps.

    # How to enter and exit "Safe Mode"

    Also, you could try "the Factory Reset" 

    Settings>System>Advanced>Reset options>Erase all data(factory reset)

    Please note that once the Factory Reset is completed, all data, apps, settings and personal information will be deleted.

    If the issue remain the same, please enter Safe Mode and charge your device to 100%, put it in idle overnight and provide me the screenshot of 


    ②Setting>Battery>3 dots on the top"Show app usage"

    Furthermore, is there any zone heating up while using/idling?
