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.

    Running an MSI won't install an older version of FIRMWARE. As far as I know, you
    can't uninstall or revert Surface firmware to an older version.

    It may be too early to tell yet, but Microsoft sent out Build 18990 and came with the newer Firmware built in.  It has only been less than two days but with testing, have not had a power drop at all.  In fact, ran the machine (Surface Laptop 1st gen) for a little over an hour with general web browsing and email and it only dropped to 93%.

    Not sure if the Firmware is experimental and if is, not available for general download for others.

    Here is the Firmware that was installed:

    Good to know you are testing James 👍, but for current production machines facing the drainage issue, the fix for now is to turn off SMT via UEFI / Firmware Settings, build 1903 - 18362.356 - And from your description it seems back to the baseline norm, As conflict with current firmware does not handle super scaler well.  disable Simultaneous Multithreading (SMT) has units that I have tested operating normally as should.

    in my case, with surface pro 4, the deactivation of Simultaneous Multithreading (SMT) does not reduce the battery draining (which I have after the August 2019 update, during normal operation and not when the PC is off). From what I understand, it depends on the "Surface Embedded Controller Firmware - Firmware 103.2614.257.0 improves battery performance" update. I hope that a new firmware update will also be released for surface pro 4.

    josèterra Surface Embedded Controller Firmware - Firmware 103.2614.257.0 is avail. for all Surface Pro machines download the drivers at the following Surface Pro 4 Drivers & Firmware - Download the appropriate version for your machine.

    Once everything is up2date, drain the battery completely and charge until 100% full and test.

    297/5000

    I apologize, I probably haven't explained myself correctly: since I installed that 103.2614.257.0 update, I have battery draining problems. Maybe, I could try to roll back the driver from device manager, but I'm afraid it could make the OS unstable, so I'm waiting for the new update.

    Can you take a screen shot of Device Manager and show all under system devices?

    So you select Shutdown from the Power menu and do not experience a drop overnight? I'd be interested in what happens if you charge to 100% and then shutdown for the night as to what the battery % reads in the morning when you turn it on again. 

    At the risk of repeating myself... 

    If you need to use your surface laptop for something work critical & on battery only, try my solution. Since there were no references to it at all, in this race for a new firmware, I imagine that noone else has tried it.. 

    I had to sit through multiple presentations from 9am til 5pm and my battery life was at 65% by the end with mixed use. (powerpoints, word docs, online articles etc) 

    My solution was to switch off hibernation**:**

    command prompt, **type****powercfg.exe /**hibernate off

    I can now shutdown and switch on like before and it works like when I first got it. 

    Good battery life and the percentage stays the same overnight unplugged.

    Obviously it breaks hibernation, but hopefully when a new firmware is released to fix the battery bug, you can reactivate hibernation by going 

    command prompt, **type****powercfg.exe /**hibernate on
