iPhone 5 on 6.1.3 issue - Battery draining like crazy!
My girlfriend got an iPhone 2 days ago and for the better part of the last 2 days, her battery's been draining like hell. I'm talking going down 5% at a time in standby and crap. We've done all the usual. Location services off, Bluetooth, crap to do with push notifications, turning down the brightness, iCloud, etc...I've been using iDevices for 4 years now, I know the basics. The thing is, I've been complaining about my battery (iPhone 4) going down like hell too. Not this drastically though. Is there any known problem with 6.1.3 regarding batteries draining, and if not, what can we do about it?
