Along with call quality, a cell phone's battery life is one of the most important considerations when choosing a handset. It's never fun to watch your cell phone die when you're in the middle of an important call. And it's no fun either to have little power when you're nowhere near a charger. While manufacturers make lots of promises about a phone's battery life, the rated times don't always hold true to real-world use. That's why CNET tests every phone we review for its talk-time battery life. To see the 20 phones that last the longest, be sure to check out our list to the left, as well as our slideshow.
In the following charts, you'll find the tested talk-time battery life for hundreds of cell phones and smartphones, past and present. Models are grouped by manufacturer, so be sure to check your phone's corresponding chart to see our test results. We'll update our lists periodically, so if you have a new handset and don't see it here, please refer to our review to see how much power it delivers.
Editors' note: As of December 2012, CNET will stop updating this cell phone battery chart in lieu of new testing techniques. Please check the individual reviews of each phone for their test results.
