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.

Any news for Surface-series firmware update from MS?
Well, mine updated and no Firmware update came across! Nobody waved a magic wand and updated the firmware to a newer version. No Accumulative update came across either - only the Windows Insider Build and the Windows Defender descriptor file. Nothing else came across.

Jason Howard from the Windows Insider team has addressed whether firmware is
baked into Insider Builds. (For the same reason, it would not be baked into
Cumulative Updates.)
The Firmware is built into the build itself. If not, it would show on the list and as you can see, it is NOT on the list! No Firmware update came across to upgrade it - just the build.
... is apparently resolved by firmware currently being distributed via Windows Insider.
OS preview builds do not contain Surface firmware updates. This would unnecessarily push Surface FW to every device across the planet installing the OS.
It's possible that a FW preview was marked to be released to users on a specific build number or higher, but we don't track Surface FW releases as part of the WIP program which is of course focused on the OS preview builds.
