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! What's going on and how can I fix this?
The laptop is only about 6 months old and the battery seems to be in good health.

This is ridiculous. I just lost 12% while my PC was shutdown for less than 3 hours.
Some research suggested that the problem might be with Window's "Fast Startup" feature. I tried deactivating this feature, but still lost 8% overnight.
This is unacceptable for a supposedly premium device.
Okay, new development (if anyone is even following this).
Check this out, supposedly I lost over 20% while my PC was shut down for less than 20 minutes... That's not possible! Not for a perfectly healthy battery that functions as expected for several hours when the PC is actually in use.
So it has to be that the battery isn't actually draining, the software is just reading its charge wrong, right?
When these devices were initially released the fast start up feature used only about 2% power overnight, this was true with Windows 10 until the Creators Update last year (around the time Microsoft decided they did not need a proper Quality and Assurance testing team (and sacked most of them). Since then the fast start uses anything from 12% to 20%.
All surface products do not turn off completly, even using a command like Shutdown in the command line does not completely turn off all the components. Some live functions remain for network wake-up and clock wake functions. But as I have found out from research the power efficiency has dropped dramatically in recent updates, and Microsoft apparently doesn't give a **** !
I have not seen anything about some of the more extreme examples of battery usage or reporting with any concrete answer, but I'd return any unit still under warrenty if it was any more that 12% at the moment. Maybe Microsoft will push out a working upodate that returns efficency back to 2%, but don't hold your breath.
