The new Microsoft Surface Pro 2 tablet now features 25% more battery life thanks to an update to Windows 8.1.
In testing done by Anandtech, the Surface Pro 2 ran over 8 hours while browsing the web over Wi-Fi. That's a jump up from 6.6 hours before the latest software update was released. The improvement also means you can play video over Wi-Fi 16% longer to 7.75 hours from 6.65 pre-update.
But the Surface Pro 2 still trails the competition by a bit, scoring 8.330 versus 9.480 for the iPad Air and 12.230 for the latest Google Nexus model.
