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.

    Yes I did. But no specific response to what might be causing the problem. They just said that we need to isolate the problem and that I should send the device back.

    I guess I’ll have to give it another try since people are saying it worked for them. (Shrug)

    I would like to report that my battery drain issue appears to be resolved after trying the multi-part step that was provided by someone on the thread:

    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

    It has been 3 days since I took those troubleshooting steps and my battery has not acted up the way it has been before the troubleshooting. I will continue to monitor it, and if it drains again from 100% to 75% while turned off then I will come back to this thread and inform everyone.

    This seems to be an increasingly common problem. Here's everything I know about it so far:

    • It seems to mainly affect Surface Pro 6 and Surface Laptop 2 units, ever since an August firmware update.
    • The problem is almost certainly software/firmware based. I don't believe there's anything physically wrong with your device or its battery.
    • It does not seem to matter how long the device is shut off for. I originally thought it was a gradual power loss over night. I've since observed that I can take my Laptop at 100% charge, shut it down and unplug it, and turn it back on 10 minutes later or 8 hours later, and either way it starts with around 75%.
    • This behaviour doesn't occur if the device is shutdown with less than 100%. For instance, I can shut it off with 96% change and 8 hours later it starts with 96%. But if I shutdown with a full 100% it will start with about 75%.
    • Microsoft can/will currently do nothing to fix this. Those who have taken devices in to MS Stores have simply gotten refurbished replacements which exhibit the same behaviour. Extensive conversations with MS Support via Twitter just took me through a series of troubleshooting measures that did not help.
    • The only thing I and others have been consistently told is to report this issue using the Windows Feedback Hub App. Make sure that you do so, and also find others who have this issue in the hub and upvote their reports. That's the only way this gets actual attention from MS. Even if the solution proposed earlier in this thread works for some people (it didn't work for me) this is still something that MS needs to address themselves so that it doesn't happen in the first place.
