After bringing my phone in for a screen replacement I immediately noticed my battery draining much faster (the battery was only 2 months old and was replaced by Apple). The next day one of the screws just fell out at my desk at work. After bringing it back another 2 times I was told it was a software issue despite the fact the battery issue corresponded exactly to the screen change... I now have to charge several times a day, one might conjecture that the new screen is of inferior quality or the battery was damaged during the ‘repair’. Either way I’ve just swapped one issue for another.
