x12 and x6 do not seem plausible. Something is very wrong.

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.

That's the case.

My CPU is at over 5GHz, 1% load and 70C at the moment. That's in a "power-saving mode".

If nothing would be wrong, it'd be at something like 1.5GHz with most of the cores unpowered.

Something is wrong with power governor then. I have an opposite experience, was able to tune Linux on a Core Ultra 155H laptop so it works longer than Windows one. Needed to use kernel 6.11+ and TLP [0] with pretty aggressive energy saving settings. Also played a bit with Intel LPMD [1] but did not notice much improvement.

I also own a 155H laptop using Linux Mint! Would you share your settings with TLP and LPMD? I am not getting not much longer battery life than Windows 11 on it after some tinkering, so seeing somebody else's setup may help a lot. Thanks!

What is the laptop, and what's it doing?

What p-state driver are you using?
