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.

This should be available on Windows Update:
October 10 release
The following updates are available for all Surface Laptop 2 devices running Windows 10 April 2018 Update, version 1803 or greater:
| Windows Update History Name | Device Manager Name |
|---|---|

So "YES", Microsoft does hide some updates!
No, this is not true. You can continue to debate this point, but if this is your
experience, you need to file this as a problem report using the Feedback Hub
App.
Can anyone confirm or deny that there is any fix/workaround relevant to the loss of battery on shutdown for the SP4 (not SP6)??
The release preview appears to only be for the SP6 correct?
Reading all of this is a mess.
In short @MorganKita it is a temp fix. In regards to what @James is saying he is emphasizing the Windows Insiders program with on going development of the @Surface line of Products & Windows, but off topic for a sec. Even Apple is facing the same issue (Currently fixed on both their i9 series Macbook Pro's & recently the iPhone IOS 13.1) So no it is not only INTEL CPU's, it's also ARM, AMD and others, it is the core programming of how the CPU can be programmed to help isolate malware for users.
NOTE: Navigate to pg. 35 and look for the temp fix for SP4 with Jose, also yes be patient if you can, the next update will soon be avail. for the general public, along with further development of SMT with Firmware.
It has turned into a mess, hasn't it? The power manager is the same on all models to include the Surface Book series. What 'fix' anybody uses on one will work on the others.
The Windows Insider Preview works on all models and also works on regular PCs and laptop made by other PC makers (HP, Dell, Acer, etc.).
The 'fix' will not be specific to any model, if that is what you are thinking about.
If you can be patient, the next major upgrade should be coming across in just few days. At this stage, I recommend to not make any changes and just wait for the upgrade. The Firmware upgrade that came across for Insiders is still classed as "experimental" and there can even be a newer version coming out.
Don't do anything, just wait (if you can).
