Hi all I just picked this case up and loving it,I do have a question about it though. How this case is it acts like the iPhone is plugged in,so the phone shows it's charging. So basically the phone uses the case battery first then the iPhones battery will kick in when the case dies. Will this mess the iPhone battery up since the case is constantly powering the iPhone battery? I just don't want to mess my iPhone up. Thanks for all the help
