Uh, I wouldn't consider that to be "supporting Linux" then. On a laptop - which isn't marketed as supporting anything other than Windows 11 - that has similar (but higher spec) hardware than the 12th gen framework I see anywhere between 8 to 20+ hours of battery life, greatly depending on load - largely equivalent to what it does running Windows.
The framework laptop would also seem to suffer from using user-replaceable DDR4 instead of, say, LPDDR5 like 12th gen compatriots generally do (higher performance, less power).
