The battery drain on my phone is becoming a joke. If i make 30 mins of calls maybe play a game for say an hour. Then my phone last around 8 hours in standard mode. If i ramp up setting to 4k etc do the same 30 mins of calls etc then it last 6 hours! Ive reset the phone numerous times. Its just getting worse. The phone is 7 months old!

Hi @Summersuns


I appreciate battery life and screen on time is vitally important.


I would first suggest to put the phone in Safe Mode which disables all the downloaded apps etc and leaves the stock ones working. 


If battery life improves then the issue is an app or launcher.


Come out of Safe Mode and start deleting your downloaded items one at a time.


If it continues in safe mode and the battery section in device maintenance does not throw up anything then I would first clear the phones file system caches by turning the phone Off and then from a set of button presses get into the system files and delete the cache files. No user info is lost this way.


If no remedy then as every last resort back up , remove any Sd card and factory reset.


Allow a few days for the phone to settle down.


A Samsung Experience Store or Samsung Service Centre can run a diagnostic test.
