try to turn off 3G. i experienced that b4 also.. i think is due to the network problem. 2 months ago my area D network got problem, and 3g signal is not stable at all. my phone keep turning from 3G to Edge and E>3G. b4 i sleep, it got 95%, when 7 o'clock, 40% only..
but if i turn off 3g at night. the whole night only use 1%.
