From an 11th gen I get about 6 to 7 with light usage, two to three with any development. It's largely a thin client at this point. Battery health is at 92%.

I tried upgrading to the ryzen and when it was good it was really good. I was able to keep a user mode libvirt vm running for dev work and mid brightness under 5W power draw. That used slirp networking, adding a bridge or default nat nic takes up about 2w to 3w of it's own power.

But like most windows laptops the suspend mucked things up. Not even power draw while asleep, but when awaking from sleep the power minimum was 10w with it more often at 20w with similar usage. I tried several wifi cards, nvme drives, port configurations etc. Also tried Fedora, Ubuntu and Nixos.

On Linux this carries over to the discussion of tlp vs power profile daemon, and soon tund. I saw much better performance and regularity with tlp, but that seems like it's not the path forward.

The steam deck shows that suspend can be fixed and done well with decent battery life under linux.
