Sleep Mode Battery Drain issue finally solved?

January Firmware for Surface Pro 4 and Surface Book

The Surface Pro 4 and the Surface Book had a constant problem with their sleep mode. Ever since the Surface Pro 4 and the Surface Book were released, sleep mode had trouble retaining battery charges. During my short experience with the Surface Pro 4, when these devices are turned back on from sleep mode, majority of the time the battery life was almost depleted.

Microsoft is claiming that this is fixed (once again). They issued a firmware update during June which according to them, may fix some of these problems and retaining battery life in sleep mode.

The firmware update issued in January did not resolve the sleep mode issue. Only a month after, in February, Microsoft announced that the Surface Book and the Surface Pro 4  would increase battery efficiency in their near future firmware updates. Ultimately, it was reported that it was the Intel Skylake Processor that had problems with conserving energy.

But in the recent firmware update, the Surface Book receives three new drivers and the Pro 4 gets two. The new drivers for the Surface UEFI (Unified Extensible Firmware Interface) is designed to improve system stability during sleep mode. It also improves battery performance when it is being charged.

There are also two other bugs fixes from the new firmware update:

  1. Stopping the Surface Book from shutting down when is it on sleep mode.
  2. Deactivating the Surface Book’s and Surface Pro 4’s touch screen when the type cover is closed

For those who did not update their Surface Book or Surface Pro 4, you can update it by going to the Microsoft website.

If you already have updated or once you had done so, please comment below whether or not you notice the fix and share your experiences.
