Gee, maybe it's because you have a million tabs open, and all of them are websites with shitty, wasteful javascript begging the CPU for useless operations to update every single tracking pixel and cookie, with up-to-the-minute anaylitics, attached to sessions that are years old, on how your eyes move over their ad banners, so that a genetic machine learning algorithm can determine which ads are most likely to convert to clicks and then sales.

Hint: It's the ad for the top 7 ways you didn't know you could get bunions, and there's a 50% chance it will convince you to buy new shoes.

yeah, chrome is in there.

but switch to safari? my thoughts a) i'm a developer, i rather like new APIs, latest HTML 5 features b) my whole company infrastructure relies on google services (and they work best in chrome, no surprise there) c) my old macbook air (2013, maverick, killed one month ago by my son with self made kombucha) had about 7h battery-life

To be fair that's not super useful information - I've never not seen Safari there when it's being used. Definitely agree that Chrome is way worse in practice though.

Chrome also turns on the discrete GPU for seemingly no reason.
