Dear Iphone user community, I have a question, or actually it is a problem for my wife's iphone and I hope this is the right place for me to seek for answer.

I'm using 3g iphone and she use 3gs iphone. She always complain that her 3gs iphone got heated up suddenly and randomly and also quite frequently, which resulted in battery power decrease rapidly. She even got panicked a few times and throw the phone to me and say it's gonna go KA-BOOM.

Before I send her phone to apple authorized store for check-ups, I hope someone here could enlighten me about my issue. Thanks

Pass few days my phone batt draining quite fast as well. Previously was okie, even I rebooted my phone still the same.

Wonder is there any Apps cause the batt drain. Nothing running on the background but still drain quite fast.
