ive read alot of people talk about doing iTunes OS updates vs OTA. people keep saying that OTA isnt as good as doing it via computer, and OTA leads to issues and battery problems. has anyone confirmed that one is truly better than the other? my iphone 5 battery is ok, not crazy awesome, but i can get 9-11 hours of use and just over 1 day of standby. just wondering if i should restore and do it via computer for the heck of it or just live with my OTA updates.
