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'm glad I found this thread. Mine started showing these issues about 2-3 weeks ago. The worst I've had was a 60% drop in 4 hours when in sleep. It's sad as this unit is less than a month old :(

    Why does it need to remain off for 10-12 hours? That part seems weird. Other than that, it just sounds like a combination of reinstalling battery drivers and recalibrating. I’ve tried both separately but not in conjunction.

    Uninstall both then proceed to turn your Surface off and keep it off for about 10-12 hours

    Hey Everyone,

    I posted a possible "fix" on the Surface sub reddit and a couple people have reached out to me and told me it has cured their battery issues.

    Goes a little something like this: 

    1. Go into Device Manager -> Battery-> Uninstall the device driver for the the battery itself and the AC Power Adapter
    2. Immediately after uninstalling the drivers, go ahead and turn your PC off. Make sure its turned completly off (no hibernate, no sleep) for up to 10 hours. Recommended you do Steps 1 and 2 before bed
    3. Upon waking up, use your Surface till the battery hits 0%, letting it turn off by itself
    4. Once you charge your Surface up to 100%, click on the battery indicator Icon and flick it from "Battery Saver" to "Recommended"
    5. Done

    This has worked for people experiencing the following problems: "Battery indicator stuck at 100%", "Battery at 70-75% when I turn my PC on"

    Thank you for the solution and I will try it. But there are two option under Batteries.

    (i) Microsoft AC adapter and

    (ii) Microsoft Surface ACPI-Compliant Control Method Battery.

    So, which one to be uninstalled or both, please.
