M3 vs M3 Pro battery test - is there a decent comparison/review out there?

[essentialist]

...I mean besides the PC Mag 720p video 30-hour battery test... I'd love to know if the difference in battery life between these two is similar to Apple's claim (M3 15hrs wireless web, vs M3 Pro 12hrs wireless web). I'm very aware of the other performance and utility differences between the two machines, but it seems like there's not a lot of chat about the power efficiency which makes me wonder if they're actually pretty similar in real world usage.

This video runs a few tests with all machines and he marked the battery drainage towards the end.
