Improved Battery Life For Microsoft Surface Pro 2 In New Firmware Update

As the Microsoft Surface Pro 2 released, users experienced poor battery performance when it comes to web browsing and video playback. Shortly after, Microsoft pushed an update that addressed the issue. What the update does is allowing the Marvell WiFi solution to drive down to even lower power states, conserving more power and hence improving battery life.

AnandTech performed tests on the Surface Pro 2 after updating to the newly released firmware and noticed a 16% increase when playing back video compared to the previous firmware tests made. Here is a screenshot with the updated benchmark results:

Also, Surface Pro 2 now manages better battery life than Surface 2. Microsoft told AnandTech that their internal target was over 8 hours, and this firmware update brings it up to snuff via a nearly 25% increase in battery life when performing a browsing battery life benchmark test. The screenshot below represents the benchmark results for this test.

A software update also rolled back the Surface Pro 2’s video drivers to an earlier version that is told to have fixed the display corruption on wake issue as well. Take note though that Surface 2 did not receive any similar battery life changing firmware update, hence no improvement for the device. Don’t fret though, as Microsoft could release one soon enough.
