Is your iPhone 5 battery suddenly not holding a charge the way it used to? Apple might replace it for free

If your trusty iPhone 5 is working well, but the battery does not seem to be up to snuff, it appears Apple has discovered that a “small percentage” of iPhone 5 devices (not the 5s, or 5c) may “suddenly experience” a shorter battery life.
Apple has set up a battery replacement process in the US and China, and on August 29th, it will be available in other countries. If your device is eligible, you will be able to get it serviced at any authorized service provider, Apple store, or Apple tech support location. If there is any physical damage to your device (cracked screen for example), that will need to be fixed.
