Underneath the back panel lies a non-user-accessible 1440 mAh Li-Ion battery which, Apple says, should last for up to 8 hours of calls or 225 h of stand-by. We ran our traditional battery test and the iPhone 5 achieved the amazing score of 51h, which means you'll only need to charge it once every 51 hours if you use it for an hour of talking, web browsing and video playback per day. Of course, your mileage will vary depending on the use but that's the standardized measure of use that makes our results comparable across phones and manufacturers.
