Google Services battery drain on Galaxy devices Here are screenshots from my three Samsung Galaxy devices:

Samsung Galaxy Note 10.1 2014 (click image to enlarge)

It seems, that in each case Google Play Services ("Usługi Google") are mostly responsible for fast battery drain. 2014 lasts only a day now (compared to 3+ days of previous version of 10.1). S4 lasts less than 24 hours, S3 toughly reaches 24 hours.

What is the cause of so fast battery drain?
For the drain caused by google play services, install the Xposed framework and the module Wakelock Terminator. The free version lets you block 1 app, and that's all you need. Open up Wakelock Terminator, choose to block Google Play services, and filter it with the following: NlpCollectorWakeLock NlpWakeLock CheckinService NetworkLocationLocator. Of course, your device must be rooted. If it isnt, try disabling location access when you're not using it
