I am at the Apple Store right now with my battery issue. I was down to 58% around 5 hours after unplugging my 6 from the charger overnight, and with 1 hour or so in airplane mode while According to the diagnostics, several apps are crashing, and they may be re-doing whatever task is causing it to crash repeatedly, thereby hogging battery life. Apparently this does NOT show in the "Battery Usage" stats. I was asked if I had set up my 6 from iCloud or iTunes. When I said that I had done it with iTunes, the Genius recommended that I restore from iCloud. I am in the process of doing that now. Should this not fix the issue, he recommends starting from scratch. (Ouch). So, here's the question: How did you set up your 6, and are you having battery issues?
