Surface users have recently been experiencing battery degradation issues, and the cause is thought to be the latest Windows and firmware updates.

Victims of the bug have taken to Microsoft’s community forum to share their experiences.

One Surface Laptop 2 user reported significant battery drainage overnight after shutdown:

Lately, after I shutdown (full shutdown, not sleep or hibernate) my fully charged Surface Laptop 2 at night, I turn it on in the morning and find that the battery has lost around 25% power overnight!

The laptop is only about 6 months old and the battery seems to be in good health.

It took only a few minutes for this user’s Surface Laptop 2 to drain 25% when they shut it down:

I also want to report this same problem. But it is not happening overnight. It seems to happen after a shutdown event. Mine was shutdown for 7 minutes and dropped from 100% to 75%,” another user confirmed battery issues with their Surface Laptop 2.

Many others have also witnessed the same thing:

I am having the same issue. Was plugged in at the office @ 100%. Drove home which was about 25 minutes and powered it up and was @ 75%. Surface Laptop 2. This started after the last firmware update.

The problem doesn’t seem to be exclusive to the Surface Laptop 2- the Surface Pro 4 also seems to be affected:

The exact cause hasn’t been pinpointed yet, and while it could be a hardware problem, the culprit’s most likely the August Windows cumulative update.

A Microsoft support representative assures us that the company are investigating the issue and that we should keep an eye out for a bug fix.
