I bought an iPhone two months ago and unlocked it with a something similar to stealing sim apporach. I am using China Mobile sim card and now the standby time of my iPhone is about 20 hours. I need to charge my iPhone everyday. I am not sure what's wrong with my iPhone? Anybody can help me in figuring out this power issue?

Is there any approach for me to check if the power management is working? How can I check my battery is ok?

some people reported the battery draining faster if there wasn't good contactivity of the x-sim and the sim-card.

maybe its not a problem..

when i first got my iphone i was using it day in day out for about a week..
and realised i had to charge the battery every day but now mine lasts for about 4-5 days without charge..

if you download something called services from installer.app you can switch off things like wifi edge bluetooth and ssh.. if you turn them all off and turn them on when you need them i have realised that saves alot of battery time because you are not connected to something all the time wich is using battery life..

thanks
