I'm going to a concert tomorrow and I was wondering if the battery will stay at 100% if I keep it off for most of the day. I'll be there for 11 hours, with obviously no way to charge...any help, or tips to keep battery up, part from brightness and wifi off would be appreciated :) Also, I'll me taking pictures and videoing during the show, so can any one guess how long it will last?
*be taking pictures,
And obviously, I don't have two spare phones, so USEFUL and accessible tips would be extremely helpful and muchly appreciated
