Hello!I have a problem with my iPhone 3g battery life, it lasts for no more than 5 hours or so and it doesnt matter what I do with the phone, if I listen to music, talking to someone or even if the iPhone on standby, at night I have to put it to charge because the iPhone just wont last the entire night (on standby) and will turn off.does someone have the same problem or know what to do to fix it?I have the iPhone for like a year and a half and the version is 3.0
