Windows Phone 7 devices battery life comparison
AnandTech has compiled a useful overview of battery life in the various Windows Phone 7 devices that have hit the market so far. Besides talk times, the test has been browsing over 3G and Wi-Fi, which wouldn't make the Super AMOLED screen of the Samsung Omnia 7 justice, since it sucks up to three time more juice when displaying white than regular LCD displays. And, as we know, most websites have white backgrounds, so it is good that AnandTech has left it out of its test.
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.
