I have read all the suggestions, and tried everything to extend battery life(Battery saving mode in GPS, Switching network from global to LTE/CDMA) and still after a month of running KK, battery life is no where as good as JB. I bought wakelock detector today and need some advise on how to use it. I'm stock rooted, and only real changes I have made are running Xposed, with Gravity Box(for full immersive mode) and G2 Tweakbox and G2 Xposed(to hide carrier information on lockscreen, and hide various other things in the UI I don't like). Thanks for the advise in advanced.
