AndroidOS draining battery massively on Android 5.0 I have an ASUS Zenfone 2 with Android version 5.0. All of a sudden today it started draining the battery rapidly.


I have made multiple restarts but it didn't help.
I tried to scan the phone with Norton and Kaspersky to identify any possible risks, but got nothing.
I uninstalled all latest apps that I installed in previous few days.


Even while it is connected to a power source, it is still not able to increase the battery charge level. I know according to the usage battery consumption can be high but only Wi-Fi is running and I'm not using the phone. And 115% usage is really very high.

The first thing I'd look for is one app that's using an extraordinary amount of resources.

Go to settings>apps> [choose an app -- I'd start with Chrome or any other browser that you use]

Then do a "Force Stop" on the suspected app.  See if that helps.  If there are any apps that you rarely use you can keep them stopped -- so you know they aren't using any battery.

It could be a hardware problem.

Disclaimer: I'm not familiar with your phone but have used 5.0 quite a bit.
