From comparative tests or from vendor specs? (Genuine question, I do not know which you are referring to)
Scroll down to the battery section
> Only 61 percent the battery life of a similarly configured XPS 13
And the XPS has an i7-1065G7 [1] vs the Framework with an i7-1185G7 [2]. So the Framework has a better screen and a better CPU. I'm not sure I agree with running that benchmark without other data alongside it like a score or the average clock rate.
For example, I put a 2nd battery in a ThinkPad once and it had the effect of locking the CPU clock to <1GHz. The battery was predicted to last much longer than normal, but it was useless as a computer.
