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.

    Surface Laptop 2, downloaded and installed via Windows Insider Release Preview. The only issue that has been plaguing me since August is my device always starting up with about 75% power after shutdown. 

    Since installing this firmware, I’ve shut down my device about 3 or 4 times, including twice over night, and it has started up with 100% each time, exactly as it should. 

    I will continue to monitor and report my findings here for at least a few more days.

    So far I still have not had a recurrence of the 75% start up issue since installing the recent Surface firmware update released through Windows Insider. This might indeed be the long awaited fix. 

    Even if it is fixed. I would really like to know what the actual cause/nature of the problem was, just out of curiosity. 

    have you installed a firmware update from insider for which surface? Did you fix the battery draining?

    this shows that the Surface firmware was not inside the build but separate. you seemed to be implying that it was hidden inside the bits for the operating system and not a separate download. Around the 6th line down I see the Surface firmware. True it may have been downloaded at the same time as 18990 (or other Insiders build) but it was a separate "package".

    The solution I'm using is for real world production machines that can not nor allow Beta (Windows Insider) Builds, as various users are stating that they have no issue, but yet their machines are not mission critical nor work sensitive compute devices.  The clear difference of real world IT /IS VS. Tinkering (Lab Environment).
