Power management is a joke. Configured as best as possible, walked in the other day and it was dead - as in battery at zero, won’t even boot. Windows would never do this, unless you went out of your way to config power management to kill the battery (even then, to really kill it you have to boot to BIOS and let it sit, Windows will not let a battery get to zero).
Are you kidding? Windows does this all the time. There have been countless times when I’ve left work with a fully charged laptop, then bring it back the next day to literal zero charge without having used it. I no longer trust sleep or hibernate mode at all for anything longer than an hour. And I’m not the only one with this problem. My partner (with a different laptop) has had the same thing happen, and so have my colleges.
I’ve got some ideas about why and how it might happen; but kind of beside the point. The point is that it is not true that Windows would never let your battery drain to zero while the computer is not in use. It does do it. Often.
In my specific case the manufacturer is Microsoft. (It’s a Surface Pro.) There isn’t anything wrong with the battery. The gist of the issue is that there are milllion-and-one different things that can wake the computer from sleep, and then a couple of reasons why it might not automatically sleep again when ideal. If it was up to me, I’d have it so that the power button was literally the only thing that could wake it. But alas, I cannot even find a way to stop it from waking when opening the case (which I would like to do to check if it has woken up from some other reason).
In any case, I’m just saying that power management can be a problem in Windows (as well as in Linux).

That’s partly a manufacturer issue, a lot more difficult problem to solve than it may seem.
