I'm seriously starting to think that my phone has a soul or emotions because it really has its days. Sometimes I can barely squeeze out 4 hours of usage before hitting the 20% mark, sending me looking for a place to charge before the day is over. (Especially if I'm not going home after work) but this past couple of days the battery has been absolutely staggeringly outstanding. I wish I could consistently get this battery life to not ever worry about running out of juice before the day's over. I'm not changing my usage habits between those dates either. I really would wanna know the cause of this volatility.
iPhone 6 space gray 64gigs. Day 16 with the phone.
I think it's a software issue. I'm almost willing to bet that once 8.1 is released, we will all see a nice bump in battery life. 6's will be 6-8 hours and 6 + will be 10-12.
