Look, I'm not saying you're wrong, I'm just saying I get 4 hours of web browsing out of my M1 air with 83% battery health so it must go deeper, like Firefox is deoptimized or something. It's about on par with my ThinkPad E14, and worse than my 2017 i7 MacBook Air, disappointingly.

Generally both Chrome and Firefox are significantly worse for battery life under macOS than Safari is.
I think the main thing is that standalone browser vendors aren’t incentivized to care all that much about being efficient; for them acing speed benchmarks and gee-whiz bells and whistles seems to be what sells better. By contrast OS vendors want battery life figures to look great because that sells laptops. This is why pre-Chromium MS Edge bested Chrome and Firefox for battery life on Windows and why Safari does the same on macOS today.
