IOS 6.1.2 huge battery drain- IPhone 5
Hi, I updated to 6.1.2 last night- my battery life was pretty much ok (lasting 1 day + with use throughout the day).
Was at 100% charge last night when updated to IOS 6.1.2- woke up with it at 20% no apps open.
Used a banking app for 3-4 minutes this morning on 3g and dropped 5%.
Saw the `upgrade` was to fix battery drain- didnt have an issue before but I certainly do now.
Any advice on steps to take?
iPhone 5, iOS 6.1.2
