My daughter has been mentioning that her iPhone 5's battery goes down fast. I just thought that it's because she's attached to it all of the time. Last night she asked if I could charge it for her so I put it on the iPad charger that I always use to charge my iPhone. It seemed like it took forever to charge. I didn't time it but I'd say that it took at least 3-4 times as long to charge for almost dead (7%) than it does for my phone. I've read some things about battery issues. Think that is the problem? Her screen has multiple cracks so I don't even know if it would be covered under warranty. It would be in pieces if they tried to take it off.
