Would somebody please take the liberty of telling me whether this iPhone battery is faulty? I've had this iPhone for 15 months now and the battery is dying at around 40%. This iPhone is on AppleCare+, something I decided was a good idea when the first iPhone I had became regularly faulty. Apple, on the other hand, don't believe this is faulty. I've spoken to them on the phone about this (they ran a diagnostic) and in an Apple Store, having had to book a genius bar appointment over 40 miles from my home. I was told that the battery was fine and the genius bar filed the appointment as an "educational opportunity" for me. They tell me the battery passes with 87% health. Tell me I'm talking rubbish. Very frustrated with Apple as you can tell. Rapidly losing my patience over the situation.
