Microsoft released a firmware update for the Surface Pro 2 not long after it was released. The company claimed the update allowed the Marvell Wi-Fi chip inside to achieve even lower power states which in turn resulted in improved overall battery life. But just how much of an improvement are we talking about? AnandTech recently put the firmware update to the test and found the improvements to be significant.
The publication ran multiple tests with their Surface Pro 2 calibrated at 200 nits. In the web browsing battery life test, the firmware update was good for nearly 25 percent more battery life. An improvement of 16 percent was also realized in the video playback test, with the updated machine lasting 7.73 hours versus just 6.65 hours without the update.
AnandTech reached out to Microsoft to inquire why the Surface Pro 2 is unable to deliver battery results on par with the 2013 MacBook Air. Redmond correctly pointed out that their tablet includes a number of sensors not found in the MacBook Air. Additionally, the Surface Pro 2 ships with a higher resolution display, an active digitizer and capacitive touch capabilities – all of which contribute to increased power consumption.
Microsoft launched the Surface 2 and Surface Pro 2 on October 22. The Windows 8.1 RT machine starts at $449 with 32GB of storage while the Surface Pro 2 begins at $899. It’s worth noting that Microsoft only released a firmware update for the Surface Pro 2, not the Surface 2.
The Surface Pro 2 is powered by an Intel Haswell processor and comes in different versions, 64GB and 128GB of storage with 4GB of RAM, as well as 256GB and 512GB editions with 8GB of RAM. The Surface Pro 2 is the follow up to last year’s Surface tablet from Microsoft sporting USB 3.0 and a mini DisplayPort ports.
The Microsoft Surface RT offers the flexibility of a Windows 8-based tablet as well as an ultrabook-like computer. The Surface RT is powered by a quad-core Nvidia Tegra processor, 2GB of memory, a 1,366x768 wide-screen display, and Windows RT. Other features include a USB 2.0 port, HDMI-out, and a vapor-deposited magnesium chassis.
The Microsoft Surface Pro offers the flexibility of a Windows 8-based tablet as well as an ultrabook-like computer.

It also comes with a pressure-sensitive stylus with palm-rejection technology that magnetically clips to the charging port, and a Full HD (1920 x 1080) display instead of the 1366 x 768 variety on the ARM-based model.
The Surface 2 is the follow up of last year’s Surface tablet from Microsoft. The Surface 2 is powered by an Nvidia Tegra 4 processor and comes in two versions versions, 32GB and 64GB of storage with 2GB of RAM. Last but not least, the Surface 2 packs USB 3.0 and HD video out.
