I'm about to give up on Android

I currently have a Galaxy Note 3. And no matter what I try to do, Android System and Android OS keep draining the hell out of my battery. I've had this issue even before the KitKat update. I've reset it, turned features on and off, installed launchers, looked through forums, got rid of non Play Store apps, and factory restored it which was a huge pain. The apps that let you see what drains battery never work anymore because of KitKat. No I'm not rooting. And I'm not constantly turning things off with a task manager because that also drains battery. Is there anything more I can do?
