Hi, i'm new with this iphone gadget, i have iphone 4 with 4.2.1 OS, and here's my problem:
i have no problem with my battery before,recently i had unlimited internet subscription for two weeks, i must say iphone's battery not so savvy when u use it for internet activity, but it's OK though. main problem is, after 2 weeks, my subscriptions is over, and i didnt extend it.
then, problems appear,from 100% full charged, my battery drainned to 10% only a night (around 7-8hours).
what happen ? i suspect that iphone still searching internet connection, i have closed wifi, cellular data and enable 3G is off.
it already happen to me twice, last time problem solved by re-installing OS.
but, it happen again after i used unlimited internet subscription, and not extend it anymore.
now, i tried disabling my push account (mail, contacts,calendar all off), i just praying it works.
if not, please help me...what happen to my iphone ?
