Surface Pro's Battery Life Extended Through Firmware Fix: Report
Road warriors rejoice? Microsoft issues an update that delivers a big boost to the company's Intel-powered Surface tablet.Surface Pro 2 now lasts longer between charges, according to new tests performed by PC enthusiast site AnandTech. After the Surface Pro 2 hit store shelves Oct. 22, Microsoft released a firmware update that allowed its Marvell WiFi components to enter into lower power states, stretching the tablet's battery life and helping users eke out more time before seeking out a power outlet. "The improvement is significant," wrote Anand Shimpi. Heavy users of the Web are more likely to experience the boost. "In our Web browsing battery life test, Surface Pro 2 now manages better battery life than Surface 2. Microsoft told me that their internal target was over 8 hours, and this firmware update brings it up to snuff via a nearly 25 percent increase in battery life," stated Shimpi. According to tests, the tablet lasted 8.3 hours in Web browsing benchmarks. Video watchers will also notice longer viewing sessions, although not to the same extent. "The improvement on the video playback side is still reasonable at 16 percent over the numbers I originally ran," informed Shimpi, an improvement of approximately 1 hour compared to pre-update benchmarks.
Reporting similar results, The Verge's Tom Warren wrote, "Microsoft promised a 75 percent increase in battery life for Surface Pro 2 over the original, and the company delivered."
