Updated the firmware and it's draining my battery. Finished charging the phone at 5am. WiFi was turned on all the time. By the time I woke up at 10am, my battery level is at 86%. This is way too fast. How to solve the problem? Before this on ICS, i do turned on my WiFi all night when I'm back at home, but I don't think the battery is draining that fast.

Googled around and some said the batter will get back to normal after a week when the phone already settle down after the update. Is that possible? =(

so far... my phone is still doing ok except for the battery draining issue. a bit regret after doing the update. didn't know it's JB.

Out of sudden after factory reset, I'm having problem with smart stay. it's preventing the screen from turning off when i'm not using it, just placing on the table. Need to turn off smart stay *sigh*

can I set my sms and messages in whatsapp to be stored automatically in external sd card if I didn't root my phone?
