Have you noticed a sudden battery life shortage on your iPhone 5? Did you purchase the device between September 2012 and January 2013? Those who answer “yes” to both of these questions may be eligible to receive a free battery replacement from Apple.

Indeed, according to a report from Forbes, Apple has launched a new battery replacement program for its original iPhone 5 model. The company recently discovered that some iPhone 5 handsets sold in the early month’s of the device’s release “may suddenly experience shorter battery life or need to be charged more frequently.”

Of course, not all iPhone’s sold at the end of 2012 or the beginning of 2013 are faulty. Apple says that the battery problems in those phones only apply to a limited serial number range. iPhone 5 owners can check to see whether their phone is eligible for the free battery replacement by going to Apple’s Battery Replacement Program webpage and entering their serial number into the box provided.

The Battery Replacement Program is officially active in the United States as of August 22. Those with qualifying iPhones can take their devices to a local Apple Retail Store – or some other Apple Authorized Service Provider – and have the free battery replacement done on site. Those who have already paid for a battery replacement, meanwhile, can still check their eligibility via the Apple website and receive a refund if their devices fall into the eligible serial number range.

This is not the first time that Apple has issued a recall of its products. Batteries in particular have been an issue for the company in the past. Last fall, Apple recalled several thousand brand-new iPhone 5S models over defective batteries. A battery recall was also done on iBook and Powerbook laptops, circa 2006.

The iPhone 5 has not been immune to issues, either. In fact, another recall is currently in place for some iPhone 5 models that have defective wake/sleep buttons. That particular replacement program includes devices manufactured through March 2013. iPhone 5 users can check their eligibility in the same way they would for the Battery Replacement Program: visiting a special Apple webpage and entering the serial number of their device.
