I have an iPhone that I bought last week. I unlocked it and everything and I am using it with Tmobile...I am having battery issues, it is draining too quick so I called the apple store and they told me to make an appointment at the genie bar...so my question is, When I take my phone in...should I restore it and just leave it how it came? cause If I do that, how am I going to explain to them the problem? have any of you guys been to the store lately with something similar? I would appreciate any suggestions..
