With what I had open (Brave, Rocket Chat, Dino, Mailspring, Putty, VNC Viewer, VC Code, Crossover, VMware Workstation (was suspended VM), and Steam) I saw ~3 hours from out of the gate, with minor improvements after TLP tweaking.
Under Windows I saw double the amount of battery life with the only difference being Outlook 16 instead of Mailspring, and Crossover was replaced with Terminal and Ubuntu running through WSL2. (which means that technically Windows was running more things than Linux concurrently.)
This is why I run Windows 11 (using WPD and Tinywall) as the host, and run Linux via VM as necessary. I get all of the touchpad features that Windows provides, and all of the hardware stability as well. Until Linux can handle the cutting edge tech in the Framework that will be situation for me for a while I’m afraid.
