Hey whats up guys Think its about that time I replace my 5s battery. Doesn't hold charge over 1 day of use. Checked apples site and my serial number is not qualified as a good will battery coverage. I can buy and replace under insurance a new 5S for $100 - but figure to wait for the 6S. Where can I get an OEM apple battery replacement done? Not some cheap knock off battery. Thanks in advance!
