Overnight battery drain issue after one ui5 update on s21 fe

[prasadroxx]

I am experiencing 30 to 35% battery drain overnight. Although network is quite stable and no app is running in background.It feels like ghost is using my phone after I slept😑

Are you serious?!

Try good guardians app from apkmirror website,in that you'll get a module named as Battery Guardian,it's helpful in reducing overnight battery drain,I've been using it for months now and it does make a difference or else u can try to put your phone on maximum power saving mode when you're about to sleep then your battery would drain around 3 to 4 percent in a span of over 8 hours.

Just done resetting the phone so can't show the battery drainage pattern. will see today night how it will go after reset.

I think the standby battery drain has improved a lot in OneUI 5. I hope resetting your device works as it did for me.

Hope so
