So my battery life has been horrible after the amber update. The battery will drain completely is less than 5 hours at times just sitting there. If I pick it up to use it, it may die even quicker. I have tried 2 hard resets, draining the battery a few times (not hard to do since it already drains itself already), a battery swap with my wife, turning off data and all background activity, etc. I don't know what else to do. Any ideas or thoughts?
