If you purchased the iPhone 5 and your battery seems to need charging more often than usual. Apple has just announced an iPhone 5 battery replacement program for phones that "may suddenly experience shorter battery life or need to be charged more frequently." The affected iPhones were all sold in the first few months of the iPhone 5's life, between September of 2012 and January of 2013. The program launched on August 22 in the US and China, and it will be available in other countries on August 29. It will be available for two years after your purchase date or until March 1 of 2015, whichever provides longer coverage.
