So I have a white iPhone 5, there is a slight gap on the top and right between the screen and band. I was told that this is on par with other iPhones. There's also a small ding on the bottom near the lightening port. With all this apple refused to replace the iPhone I'm also having battery issues. This is a Verizon iPhone so I'm using it with tmobile and I'm being told that using tmobile is causing my battery issue. Is there anything I can do about this?
