Battery issue in Note 8 (Very important please)

[Ramy Adly]

Dear all,
I have an issue in note 8, now when the battery reaching 25% or 22% the charging is going down very fast, like 3 or 4 minutes to go from 22% into 8% and then the mobile powerd off automaticaly with 0%.
I need your urgent feedback.

It is rare, but sometimes a single app can drain a significant amount of battery.

If you have a badly made app installed it can still drain your battery faster than you'd like. Unfortunately that means you still need to be diligent about checking battery usage — particularly if you're tipped off by a battery that isn't lasting as long as it should.
To check on apps that are using a large chunk of your battery, head into the phone's Settings, Device maintenance and then Battery to see a readout of which apps are using significant power. It isn't uncommon to see apps using 1-3% battery over the course of a day, but if you see one in the 5-10% range you should consider uninstalling it, or at least clearing its data and starting fresh with it in case something had gone wrong with its configuration.

That's all what i have when I go to device maintenance and then battery, Appreciate your support please.

Check to see if you have any un-monitored apps using battery. I check that periodically and remove any from the un-monitored apps.

Reboot to factory and delete all third party apps. Add only the essential ones, one at a time. See which ones are battery hogs.
Social media is the worst, weather apps, Internet security apps.

I would suggest doing what others have suggested. Do a factory reset on the device and see how it goes. My note 8 was feeling sluggish and battery was draining very fast. Decide to replace it through Samsung premium. So glad I did, as if resolved the problem.

just got mine 2 days ago,arranged all my settings, seemed fine until today. In 20 minutes i went from 70% to 61% , 1% just disappearing after a restart. I'm going to try the factory reset when i get back home since i was in a hurry and just transferred everything from my S8. android system is standing strong on 2nd place
