Battery Drain from mysterious wake locks I have an huge battery drain issue on my OnePlus One running Android 4.4.2 on stock ROM CM11s O5Q with FrancoKernel R35. I googled and searched so many times but couldn't find anything and I am really desperated now. And hope you guys can help me out.

So, some time ago I noticed that my battery drains over night in "Deep Sleep" 2-8% per hour which is really unusual. I installed "BetterBatteryStats" to look up whats going on, noticing that strange wakelocks are draining my phones battery. Here are to wakelocks event0-875 and event2-875 (see screenshot, this screenshot was taken after charging so dont wonder the -0,5%) which iI dont know and I also dont know to what they belong to.

I read so far that event0 are androidOS stuff wakelocks and at the end of a day I have round about 30-40% left mainly drained buy AndroidOS, as I can see from the built-in Bettery Stats. We have to see that its a 3100mAh battery and i usually dont use my phone at all during the day.

I already greenified some apps to see if its an app which is causing the drain but no success so far. 

Today in the evening I cant post you another screenshot from WakelockDetector app. The statistics resets after charging the phone.

I hope you guys can help me, thanks so far!

If you're rooted, try Greenify. It will hibernate all the unused apps and thereby releasing resources which sucks up your battery juice.
