Apple has initiated a battery replacement program for a limited number of iPhone 5 units. According to the company, ” a very small percentage of iPhone 5 devices may suddenly experience shorter battery life or need to be charged more frequently.” The affected iPhone 5 units were manufactured between September 2012 and January 2013 and fall within a limited serial number range.
Apple has already started the program in the US and China, and will bring it to other markets on August 29. You can check whether your iPhone 5 is affected by entering your iPhone’s serial number here. You can find the serial number by going into Settings > About. If your iPhone 5 comes under the affected list, Apple will replace your phone’s battery free of cost.
Earlier, Apple had to initiate a charger replacement programs earlier this year as well as in 2013. Last year, Apple also applied the take back program to third-party chargers where one could get their non-Apple chargers replaced with original Apple chargers at a discount.
