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.

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.
That's the case.
