Microsoft's Surface Pro tablet is a full-featured machine – and it eats battery life like one, too.
As testers have discovered in recent days, the Surface Pro runs out of juice after about four or five hours, give or take. (By comparison, the Apple iPad, one of the chief Surface Pro competitors on the tablet side, can go up to 10 hours without a charge.)
The good news: Microsoft may be mulling the release of some battery-extending hardware. In an AMA over at Reddit (hat tip to PC Mag), Panos Panay, who heads the Surface division at Microsoft, discussed "future peripherals that can click in and do more."
