Apple iPhone5 battery replacement program if you have issues
 

Stumbled upon this trying to figure out why my iphone 5 battery is a fail. Turns out apple will replace certain serial numbers phones free.

Small number of units affected my ass. I have 3 of them, and all are eligible. lol. Got my first one done, at grand central terminal. Took about 1hr.

Follow below link, call apple to schedule support. Don't bother with the authorized retailers. They are complete shit, and can't do anything right away.
