my iphone 3GS randomly turns off when my battery % below 50%. I duno what are the causes ..but for now I tried to charge my battery to 100% and then drain it completely and recharge in order to calibrate...

if clean restore is needed...can I noe how can I backup and restore my game data later on?

thank you

i tried did a clean restore then restore my back up data few days ago... but the problem is still there
laz nite i tried calibrate my iPhone..now still charginig
i wonder constant use of Battery Doctor Pro or such apps will lead to battery problem?
cos the charging process is longer then normal charge without any apps

i tried clean restore b4 as well

can somebody help me?

for ppl who complain bout battery issue...try sign out ur app store acc

still cant solve the drainage when using it thou

URGENT!!

anyone with iPhone battery drain
try and dl free app called Netstat

and check for the sockets (active=green, inactive=red)
I had those sockets with over 14k hours duration

i had a feeling these are the culprit

can someone check back with me?
