The difference in battery usage is very noticeable on macOS.

I use Brave and don't notice a difference at all. Is it only supposed to be happening on Chrome/Firefox, or any non-Safari browser?

It’s a Chrome problem with Firefox somewhere in the middle. It’s like 4 hours battery life difference on an M1, too, and since I use a hosts file for ad blocking I don’t think it’s just that.

I use Firefox and it's fine on the battery.

I have used Arc browser for a bit. It's Chromium-based. It didn't seem to have a bad effect on the battery.

I haven't used Chrome in a few years now, but it used to be a major CPU, memory and battery hog. I don't know how it fares these days.
