Is that iPhone battery not lasting as ling as it should? You could be eligible for a free replacement battery from Apple. The company say some phones “suddenly experience shorter battery life or need to be charged more”.
Before you get too excited, the recall is only effecting iPhone 5’s purchased between September 2012 and January of 2013. Apple says it’s only a “very small percentage” at that.
