Apple has initiated a battery replacement program and promises a free replacement with new batteries for all iPhone 5 models manufactured between September 2012 and January 2013 and fall within a limited serial number range.
The company claims that a very small percentage of iPhone 5 devices experience shorter battery life or need to be charged more frequently. If your iPhone 5 is experiencing these symptoms and meets the eligibility requirements, Apple will replace your iPhone 5 battery for free. If your handset has any damage such as a cracked screen, which impairs the replacement of the battery, you need to resolve this prior to battery replacement.
