Not sure, but my MSI laptop has a built-in program to discharge the battery and recharge it. It wants you to run it every three months or so, maybe yours is doing something similar without the program.
At least the timing seems to be about the same. Actually there may even be a program doing it as with your laptop. I got rid of some stuff when I got the thing but didn't in any way 'deep clean' as I mostly just use it as an eBook reader. There could well be an app that does this on my surface that runs in the background as a process or service automatically.
Actually partially off topic but still concerns batteries... I read an article a few months ago that surprised me a bit. Apparently browsing the net uses more battery than watching a movie. Don't know if the article was accurate but, if so, is a bit of a surprise to me.
<edit>Actually I take back the thought that there may be an app on my Surface since I upgraded it to Windows 11 and then, later, wiped it and went back to Windows 10. If there is something similar to the app on your laptop it would have to be hardware based.
