I hava a friend own a ip4 recently he also get this problem. His phone never jb b4 on IOS5.01.
i was help him full restore from 5.01 to 5.01 and jb using ifaith. But no luck the battery increasing from 10-20% auto shut down and showing the empty battery.
And then i found out his phone charging 100% only used 1.15minutes compare with my ip4 difference around 45minutes.
And so i ask him charging the phone to 2hours then only pull out the cable. After few days the problem solve from 20% drop to 5% and now become normal.
