Hello, I have a developer version of iOS 7.1 and the iPhone started out quickly. iPhone standby time was 5 hours and 9 minutes was used - flashlight 43%. I did downgrade to 7.0.4., - The non-renewal of a backup torch standby hour, 5 minutes use - flashlight 90%. Push notifications, automatic brightness, iCloud everything off in the background did not run, no data do not back down, despite sharply torch is coming. Makes me since Friday - when I was connected via a USB cable unofficial I started fooling around - windows 7 reported a higher current through USB, I do not know if it is possible, but I think it damaged my iPhone battery, meet it anyone?
