If you find your iPhone 5 runs out of juice too quickly, Apple has a fix. Well, maybe they have a fix. Apple has admitted their iPhone 5 battery is faulty. Yay for Apple. And they have been replacing some batteries. Unfortunately customers have complained to us that Apple won’t replace their iPhone 5 battery even though their phone doesn’t last a day. According to Apple, the problem affects only a very small percentage of phones, which they claim can be identified from a phone’s serial number. We believe the problem is more widespread than only a few phones. As a result, customers are missing out on value for money.
