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?
