Read the following article and answer the question.

I got a 3 G iPhone a couple of weeks and and the battery goes down so quickly I ' m starting to wonder if there 's a problem with my actual phone . For instance , I charged it for about 4 hours yesterday afternoon and since then I have had a three minute phone conversation , sent a few texts but that 's about it and today the battery was in the red warning that it was getting really low . I did n't even go on the internet , take photos or play games since last charged .

What happens after i get my 3 g iphone ?
