I am experiencing an issue with my Galaxy note 20 5G, Android 11.
The battery drains from 10% to 0% (shut down) in just a few minutes.
All suggested attempts to improve/diagnose the issue do not work.
Any suggestions before dropping the phone to a Samsung Assistance shop?
someone suggests with *#0228# on dial pad ... not sure this is safe or the solution. It might try to reset the phone first?
