Hey guys,
I have changed registration set up on my phone,and the draining battery problem is gone for the past 4 days now. Follow these steps:-
1. Options
2. Advance Options
3. Applications
4. Press Menu and choose Modules
5. Scroll down the long list until you reach "REGISTRATION"
6. Press Menu and choose edit permissions.
7. Choose deny for all three choices.
8. The phone will restart and that will be the end of the battery drainer.
Good Luck and Have sweaty summer
