NEW YORK - Apple has issued a recall alert for people who have an iPhone 5.

The tech company says a very small percentage of iPhone 5 smartphones may suddenly experience shorter battery life or need to be charged more frequently.

Only smartphones sold between September 2012 and January 2013 are eligible, and only those that fall within a certain range of serial numbers.

People having their batteries replaced are being advised by the company to back up their data to iTunes or iCloud first before getting the phone fixed.
