So my phone has a terrible battery life (Droid RAZR M) and I have to charge it often. I've been looking at what's been draining it, and over 30% of the battery use is the Android System. Below that is the screen, at 14% (fair enough), and then the "Android OS" at 9%. Why is the system draining so much? Before my screen would use a ton, but now I barely use my phone in fear it will die, and yet the system is still draining it at a rapid pace. What can I do to fix this? I've disabled smart actions, but hasn't even made a dent, over 10% gone in the past hour and I haven't even used it.
