If you get a laptop with removable batteries, it doesn't really matter. Just carry a backup battery if you need it and you outdo modern laptops with non-removable batteries.
You can just buy batteries that will do USB-C PD.
Then you get a versatile external battery solution for charging multiple devices!
If it makes you feel any better, this machine replaced my previous daily driver because I realized that the machine I'd been thinking was "surely just like 5 years old right?" was 11 years old.
Replaced in quotes because for the covid years I used a desktop and didn't have to be able to function outside often enough to bother with a laptop.
Considering that 5 years ago is 2019, I figure that efficiency gains are probably also not as dramatic as I'm imagining.
