Windows update boosts Microsoft Surface Pro 2 battery life by 25%

Windows update boosts Microsoft Surface Pro 2 battery life by 25%Software updates can be a bit of a pain sometimes, but if you're a Microsoft Surface Pro 2 owner, the recent firmware and driver pack update is one you'll be quite happy to install.

That's because battery tests have revealed it results in a massive 25% jump in the Surface Pro 2's battery life thanks to streamlining the power requirements of the Windows tablet's Wi-Fi hardware.

Given the criticism (by some) of Windows 8, it's ironic that it's a software update that gets the plaudits for being behind a hardware improvement.

But so it is: Microsoft said one of the goals of the update was to reduce the Wi-Fi hardware's battery draw, and tests done by Anandtech appear to put a big tick in the job done box.

Video playback via Wi-Fi saw battery life jump by 16% with the update installed, rising from 6.65 hours to 7.75 hours.

The figure for general web browsing on Wi-Fi, meanwhile, jumped even further, rising from 6.6 hours to more than 8 hours.

As the graph above shows, the Surface Pro 2 still lags behind several tablet rivals. But given the theoretical nature of such benchmarks, the important comparison is to the pre-update Surface Pro 2 itself, and in that sense the figures speak for themselves.

Good thing both M$ and Apple have done some real improvements.
Mavericks has hugely improved battery performance on our work Macs.

Very impressive for an x86 tablet. Almost removes the battery life issue (vs ARM machines). They just need to work on slimming it down for the third outing.

£719-£799 without Touch or Type cover is still a massive turn-off though. As much as I would like to buy one, I can't justify that kind of money. Try <£700 with a Touch Cover.
