Smart devices may be getting faster, better, thinner and all that, but battery life is (to me) the most important aspect of any smart device, especially a smartphone. I hate having to charge my phone during the day, and I can't wait to get to the point where we're charging these things for week-long use.
Well, Which? test labs, who insist they are completely independent of any manufacturer, magazine, or website, have compared some of the latest and greatest smart phones such as Samsung's GALAXY S III, HTC One X, Sony Xperia S, Apple's iPhone 4S, and more, as well as the average 101 mobile phones they previously tested, and compared them under medium 3G receiption levels to get a realistic estimate of real-world usage.
The results of this are very interesting, Samsung's GALAXY S III smashes it out of the ball part with 726 minutes of calling, equivalent to a 12-hour session. HTC's One X was second with 635 minutes and Apple's iPhone 4S came in at fourth, with just 467 minutes of call time.
