Extremely dependent on a number of factors, mostly hardware and configuration. I had a Thinkpad T480 and on a stock fedora install it definitely died faster than W10, but after setting up TLP and Powertop I squeezed ~2 more hours of use out of it than Windows could manage. Ditto for my framework 13, I get all day battery life on NixOS but when I’ve tested windows on it I lose a few hours immediately

What’s the name of that robot ipod dog I loved that thing
