after jb....my i3gs drained a lot faster than before....
only can stand 1 day long with edge on

after i calibrating the battery : 0%->100%->0%->100%
and switch off edge+3g in sbsettings, i turn it on only if I am at out side and want to surf the internet..

usage of my phone now is 5 hours +, standby 1d17hrs
and still got 11% of battery to go....

best record since i bought at 31/3
