I recently got the 7Plus at the end of October, and set it up as a new phone. Starting off the battery life was great.. I would have 70% or so at 7pm. Recently I started noticing poor battery performance and came to the conclusion that my usage and standby time are identical. I'm thinking this has some relation to my fast draining battery. I already tired killing all the apps, doing a hard reset, and letting the phone die but the problem persists. The individual app usage times don't correlate to the usage and standby times either. Any ideas?
