A small number of handsets sold between September 2012 and January 2013 have been found to have problems regarding recharging and battery life and so Apple will be swapping out the bad batteries with new ones, free of charge. So to help consumers determine whether their iPhone 5 qualifies for a new battery, Apple has set up a dedicated webpage where they can enter their handsets serial number. If it matches, consumers can take the affected phone to an Apple authorized service provider, to the closest Apple retail store or to have it changed remotely via Apples technical support service.
