Galaxy S5 Battery Drain Galaxy S5 (unrooted)

My battery drain isn't dreadful yet, but it isn't getting better.

I can't narrow down what is causing it.  I have tried keeping my sync turned off, keeping google location reporting services off, even keeping my data off.  I can't narrow down at all what is causing this.

Anybody else have an idea or in a similar situation?
Had the same situation, I rooted and installed some app management apps, and stopped autoruns of many apps like maps, games, etc. I also removed some stock apps that I don't use which runs in background like Samsung apps. I recommend "System Cleanup" app for this .
