Windows Phone 7 devices battery life comparison
The LG Optimus 7 has fared best out of all WP7 handsets, thanks to the larger battery. The current and previous generation of Apple's iPhone have done best in web browsing, but the Motorola Droids are performing incredibly well in talk times. The Windows Phone 7 participants - LG Optimus 7, HTC Surround, and Samsung Focus, are somewhere in the mid-range and below, throughout all the tests. Of note is the solid performance of the Dell Streak, despite its 5" display.
