Some owners of the iPhone 5 have been experiencing trouble with the device's battery, and Apple today launched a replacement program to remedy the problem. Apple claims that the faulty devices were sold between September of 2012 and January of 2013 and suffer from shorter battery life and the need for frequent charges.
Only a "limited serial number range" was affected by the problems, according to the Cupertino company, and you can see if your device is listed among them by entering your serial number over at Apple's replacement site. Should you find that your serial number qualifies, you can exchange your device's battery at Apple Authorized Service Provider, an Apple Retail Store, or via Apple Technical support.
