Apple extends iPhone 5 battery replacement program into 2016
While Apple did not formally announce the change, language on the program's dedicated webpage was modified to reflect a new coverage period extending to three years after a device's first retail sale. The updated page was first spotted by iPhone in Canada.
Prior to the change, iPhone 5 owners could swap out faulty batteries for "two years after the first retail sale or until March 1, 2015," whichever provided longer coverage.
