I have batery drain with the update to ios 5.1.1. I just take the cell of the lock screen and do nothing, and in seconds (300 seconds) i see going from 24% to 9%.
What's going on? I think updates are to solve problems, not get new ones!!!
People. For me, the batery loss realy occured. The heat to, o lot. But i did the shutdown and restart then the phone is ok again. Is all right know. For does who think there is no problem and this is all mistaking, try have a normal phone use for 1 year and then in the update the thing changes drasticaly to heat and battery loss. The 1 year time that all was ok is the parameter to know what we are talking about. Wake up.
