These figures are very plausible. Most Linux distros are terribly inefficient by default.

Linux can actually meet or even exceed Window's power efficiently, at least at some tasks, but it takes a lot of work to get there. I'd start with powertop and TLP.

As usual, the Arch wiki is a good place to find more information: https://wiki.archlinux.org/title/Power_management

Those numbers would imply <1h runtime, or a >50W consumption at idle (for typical battery capacities). That's insane.

I've used Linux laptops since ~2007, and am well aware of the issues. 12x is well beyond normal.

At least on Thinkpads over the years, I've never seen anything remotely close to that either. I've had my Thinkpad x260 power draw down to 2.5 watts at idle, and around 4 or 5 watts with a browser and a few terminals open. That was back in 2018! With the hot-swappable battery on the back, I could go for 24 hours of active use without concern.

		I get below 5W at idle (ff and emacs open, screen at indoor brightness, wifi on) on my gen11 framework. Going from 8 to 5 required some tinkering. I don't think I ever saw 50W at all, even under load; they probably run an Ultra U1xxH, permanently turbo-boosted. For some reason. Given the level of tinkering (with schedulers and interrupt frequencies), it's likely self-imposed at this point, but you never know.
