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.

    I never did "skip ahead" but when I try to switch to the "release preview" as you suggest I get the message below. Once I leave the settings menu and return it seems that I'm back on "slow (recommended)". 

    Maybe I'll just opt out of this whole Insider thing and hope that the fix is released publicly soon.

    If you joined SKIP AHEAD and not RELEASE PREVIEW there could be all kinds of
    other issues that muddy things. 20H1 (Skip Ahead and Fast Ring) are early betas
    for next springs release. If you are within 10 days, roll back to your previous
    version of Windows. Leave Insiders. Reboot twice after rolling back. Then join
    release preview. Release Preview is drivers and firmware and they are rolling
    out 1909 (19H2) and not next years betas.

    Make sure your insider settings is set to "Skip - Skip ahead to the next version of windows"

    NO. Not skip ahead. That would install a very early version of Windows destined to be released next spring. RELEASE PREVIEW is the ring to join if anyone wants to try this firmware. Release Preview has the least risk and the firmware is available to this ring. 

    If anyone has joined Skip Ahead as a result of this message, consider IMMEDIATELY

    1. roll back to the previous version of Windows and LEAVE the Windows Insider Program
    2. Reboot twice
    3. Rejoin Insiders and specify Release Preview.

    I don't see Firmware Update 241.1.139.0 yet either. Might not apply to Surface Laptop 2? Seems to be for Surface Pro.
