A firmware update released in late October for Surface Pro 2 improves the battery life longer than expected.

Microsoft released a firmware update alongside driver pack for the Surface Pro 2 in late October, which improves the battery life of the tablet more than expected.

The results learned from AnandTech, who carried out different benchmark tests and found a significant improvement on autonomy front.

The result shows the battery is able to offer autonomy of 8.3 hours while browsing the Web on Wi-Fi compared to 6.6 hours of the original Surface Pro 2 without the update. It’s an increase of almost 25%, which puts the device in direct competition with the durability offered by Nexus 10 2014 Edition, Samsung Galaxy Note 10.1 and Asus Transformer Book T100.

The update has also greatly improved the performance of Surface Pro 2 when you play a video. Now the device provides 7.7 hours of insured use against 6.6 hours from the original firmware. However, Microsoft tablet is still not nearby the NVidia Shield, Nexus 7 and iPad 4, which respectively provide 13.5 hours, 12.2 hours and 9.4 hours of browsing over Wi-Fi.

The benchmarks clearly show an indication of how the new firmware has improved the performance of Surface 2 Pro with a good margin, but the results will vary a bit “depending on the use.”

In any case, it’s interesting to note that Microsoft has managed to release an update to increase the energy efficiency of the tablet, without adding new hardware.

For your information, the update was released in late October, weighing around 158 MB. The package also contains drivers for all of the components in the Surface Pro 2 device, as well as updates to the system firmware that have been released via Windows Update.
