As your iPhone 5 ages, the battery will naturally lose some of its ability to hold and deliver a charge — but how much is not enough? If you need a recharge after less than an hour of usage, you’re a good candidate. A few hours? Maybe.

As it turns out, Apple has determined that a very small percentage of iPhone 5 devices may suddenly experience a shorter battery life or need recharged more frequently. Apple says that the affected devices were sold between September 2012 and 2013 and fall within a limited serial range.

Check Your iPhone 5 for Battery Replacement Eligibility

Even if your battery is working OK, you can still check your iPhone 5 for replacement eligibility — after all, who wants to be on vacation and suddenly experience a dead battery that won’t hold a charge?

Apple’s iPhone 5 Battery Replacement Program page has a form that will let you drop in your iPhone 5 serial number to check its eligibility.

Of course, according to Apple the odds of a truly defective battery seem slim.

If your iPhone 5 is not covered, don’t despair — you have two additional options to give you the battery power you need. Check out “How to Replace an iPhone 5 Battery — or Get a Battery Case” for details on how to replace your battery yourself with a reliable battery and installation kit, as well as how to choose a battery case.

I've been writing about the tech industry since the birth of the email newsletter, and I still remember the clacking Mac keyboards from high school -- Apple's seed-planting strategy at work. I'm a big fan of elegant gear and great tech, but there's something to be said for turning it all off -- or most of it -- to go outside. Online I like to call out cool stuff on Wicked Cool Bite and blog with my buddies at Man Makes Fire. To catch me, take a "firstnamelastname" guess at the url of this site.
