Battery drain overnight while 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! 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.

Please see https://support.microsoft.com/en-us/help/4469839/surface-laptop-2-update-history

This should be available on Windows Update:

October 10 release

The following updates are available for all Surface Laptop 2 devices running Windows 10 April 2018 Update, version 1803 or greater:

Windows Update History Name Device Manager Name
Surface – Firmware – 145.501.139.0 Surface System Aggregator– Firmware<br><br><ul><br><li><span>145.501.139.0 helps improve battery life.</span></li></ul>

    Correct, Microsoft tests firmware with insiders, but firmware is not embedded in
    insider builds. It will be sent to production whenever Surface engineering
    decides it is ready and this update is not tied to Windows operating system
    Updates in any manner.

    I don't think 19H2 can solve, since it is a W10 release not specific for the Surface. It is necessary for MS to release a new firmware for the Surface line and independently on a new W10 release.

    I thin anytime on or after October 2nd after Microsoft has their event.  The new RTM should be shipping out but will be metered to not overload the servers.

    My (hopefully) final report:

    It seems safe to say that the issue which I originally began this thread for is fully resolved by the latest Insider Preview Release Surface firmware. 

    If you are not in the Insider program, I'm sure that this firmware will be released to the general public soon.
