Battery Issue

[LanceV]

I am concerned. Everytime when i wake up in the morning, my battery drains up to 10% or a bit less even if all the background apps are off and only my wifi is on. Normally it drains 1-2% but now it's draining that fast and i only got this phone a year ago.Based on the battery usage at 12-2AM,  CPU (57.7%), phone idle (30.1%) and 2-4 AM CPU (58.3%), phone idle (30.4%)

Any thoughts with this issue? I'm quite concerned considering this phone has a big battery capacity.

Hello @LanceV 

It looks like there might be something working in the background, has your phone been updated recently?

There could also be something forcing the phone to work extra, normally I would recommend a reset to check so that it's not the OS problem, as a clean install solves 99% of the issues.

If you updated software from one version of android to another, it is highly recommended to formatt the entire system to get rid of glitches.
