Early battery death affects phones sold between September 2012 and January 2013.

If you purchased the iPhone 5 early in its life and your battery seems to need charging more often than usual, pay attention: Apple has just announced an iPhone 5 battery replacement program for phones that "may suddenly experience shorter battery life or need to be charged more frequently." The affected phones were all sold in the first few months of the iPhone 5's life, between September of 2012 and January of 2013.
Apple's program page, linked above, will tell you if your phone is eligible based on its serial number, which can be found in iOS' Settings app under the "About" subheading. Affected users will need to take their phone to an Apple service provider, an Apple Retail Store, or make arrangements with Apple's phone support technicians.
