iPhone 5 very fast battery drop without touching it.
My iPhone 5 dropped from 70 % to 11 % in maybe 1 hour,even I didn't touch it. When I picked it up from the pocket it was very warm. When I turned of all internet (3G + data) it got cooled and started to drop battery normaly.Before this happened I have as long as I can remebered also had a very poor battery. What is wrong with it? Is it a bug, a setting or hardware?
iPhone 5, iOS 6.1.1
