Anandtech - 25% increase in battery life with firmware update for Surface Pro 2.

Anandtech is reporting that Surface Pro 2 battery life improved by 25% with the firmware update provided by Microsoft.

8.3 hours of web browsing with the new firmware update which is up from 6.68 hours before this update.

7.7 hours of video playback Vs 6.6 hours before this update.

More than 8 hours battery life for a tablet with core i5, FULL HD display is great in my opinion.

What do you think?
