Having trouble with your iPhone 5 battery?
You might be eligible for a free replacement.
Apple said "a very small percentage" of iPhone 5 smartphones may "suddenly experience shorter battery life or need to be charged more frequently."
Only iPhone 5 smartphones sold between September 2012 and January 2013 are eligible, and only those that fall within a certain range of serial numbers.
Apple has opened a website that allows people to determine whether their phones are eligible.
