Did you get the Apple iPhone 5 during the first five months of its availability? Are you experiencing shorter battery life or find the need to charge your iPhone 5 more frequently? If the answers to both questions are "yes", you may be eligible for the iPhone 5's battery replacement program.
According to Apple, a small number of iPhone 5 units sold between September 2012 and January 2013 may have the above mentioned battery issues. It recommends users to check their eligibility for the program by keying in the serial number of the iPhone 5 on its website.

For iPhone 5 users in Singapore, they have to head to Apple's authorized Service Providers to have the battery replaced. Below is a screenshot with the addresses of two service providers in Singapore:
