Surface Pro 3 gets small firmware update to improve sleep mode battery life

Microsoft is now rolling out a small, but no less useful, firmware update for the Surface Pro 3. This update only contains two changes, but the most notable is a bump in battery life while the Surface Pro 3 is in sleep mode.

Here's a look at what's new in the latest firmware for the Surface Pro 3:

  • Surface Pro Embedded Controller Firmware: 38.13.50.0 improves battery life during sleep.
  • Surface Pro UEFI: 3.11.2150.0 improves PXE performance on IPv6.

There aren't any security-related updates involved here, but any boost to battery life is a good thing — particularly for a device that has had its share of battery woes. If you're using a Surface Pro 3, you should be able to grab these firmware updates now via Windows Update.
