Iphone 4 Battery life after 5.1 update
I installed the 5.1 update last evening. Before the update, I could go a full 12 hr day with out recharging my iphone. Today it was on low battery by 2;30 PM which is only 6 1/2 hrs. Is there a way to undo the update as this battery life will not be acceptable.
iPhone 4, iOS 5.0.1
