I have this same problem more than 1 year I tried all solution from google ;/ .After this method my phone worked 4 days on battery, but problem back. Battery using is around 20% / hour. Localization options are disabled, power saving enabled. Nothing helps...Even a new battery.
It's seems this problem is connected with 4.4.2 upgrade. Did someone tray reset mobile to factory settings and don't upgrade again to Android ver 4.4.2?
