Here is my short story .. I bought my iphone 5 befor one week ago and it was on ios 6.0.1 and every thing was good ;(. Befor a couple days apple has released ios 6.0.2 .. When i updated it to latest after first full charge for the battery i noticed that the battery is draining faster than befor .. I thought that the issue happend only with me .. So i decided to make a second test to battery to see if the problem happend again but i did Some steps to be ready for the test & here is the steps:

I turn on then turn of these :

1-Bluetooth

2-celluler

3-3G

Then i used the iphone .. I noticed that the phone still only 6 and a half hours!!! And the charge is 3% ;( . Today i turned the wifi off to see if the problem happend again and i will tell you guys the update later. If it's happend to you and if you fixed it .. Pls give me your solution to fix that issue .. Hopefully That apple will fix the issue in the next software update .
