Yeah, same experience here. The worst part is I can't even figure out how to debug this stuff. No idea where things are going wrong. I've gotten as far as dumping ACPI tables and disassembling some of its code but I can't find anything relevant.
What is Windows doing that Linux isn't? It can't be so insanely difficult, can it?

Yup. Gotta choose one of them, can't use hybrid graphics.

I think it's due to power management issues, especially the dGPU which can't be turned off due to lack of hybrid graphics. On my laptop I got great battery life after disabling the GPU in the firmware settings.
Also, pretty much everything is GPU accelerated nowadays. Even terminal emulators. Kitty for example will cause massive power usage spikes.
