Samsung made much ado over the Galaxy S III's 2,100mAh battery, but we've been wondering whether or not that power pack was a major perk or just a necessity to offset that hefty Exynos 4 Quad. One of what looks to be a growing number of escaped pre-release devices was put through the ringer in battery tests and came out looking spic-and-span: it lasted for just over 10 hours for video and voice, or long enough to make even a tablet like the new iPad or Transformer Prime break a sweat. Web browsing wasn't quite so hot, though, which at a bit over five hours was well behind the seven hours of an iPhone 4S. Don't expect the seemingly infinite battery of the Droid RAZR Maxx, and don't be surprised if final devices handle differently, but those with the international Galaxy S III should make it through at least a few interminable meetings watching their favorite reruns... not that we'd condone such a thing.
