So I have an appointment with an Apple Genius tomorrow to have my iPhone 5 battery checked out. On average I usually can get around 6-8 hours of usage and half-day to full day of standby from full charge. It can really fluctuate. I have full LTE, WiFi, no bluetooth, most location services and notifications off, push e-mail on, brightness turned way down w/ auto on. I have tried restoring from new and doesn't seem to make much difference if any at all. As of right now I'm at 5 hours 17 minutes usage and 7.5 hours of standby with battery at 24%. I have an eerie feeling they're just going to say its normal, get over it. Perhaps I'm overobsessing over it. Just wondering what you guys think would happen if I do go tomorrow?
