Apple started rolling out its Battery Replacement Program internationally today, offering free battery replacement for a subset of iPhone 5 devices that were sold between September 2012 and January 2013. The company notes that "a very small percentage of iPhone 5 devices may suddenly experience shorter battery life or need to be charged more frequently." iPhone 5 users that are experiencing these symptoms can go to a dedicated page on the company's website to check their device's serial number and see if they are eligible for a free battery replacement.
