some things I've noticed: Mobil Safari seems to be using the search bar to hijack my google search (Particularly for locations which open in apple maps)
Although I'm mostly linux these days I went to install an alternative browser on a windows machine (using edge to download). I mentioned this in another post, but edge seems to watch for "chrome" or "firefox" downloads and politely reminds you that 'Edge is a great browser with added "trust of microsoft"' (A company who happen to be watching when you download a web browser).

Linux seems like an OS that is way more respectful.
Now you get the benefit of Windows power management (and that beautiful laptop battery life) but a web browser Microsoft isn't going to mess with.
This sounds hilarious were it not the way I actually work.
PS: I'll also mention that VSCode from Windows to WSL2 + Debian is a mind-blowingly wonderful thing, I don't know how it works but it's near magical as a dev environment when you need a full Linux but like having battery life.
What kind of system are you running?
On my thinkpad, arch install squeezes 9 hours after 7 years of use.
On a dell XPS I'd get about 13 hours with the gpu disabled and display set to 1440p instead of 4k. Sure you might say "but I need my GPU and 4k 15'' display" to which I reply eh maybe but I don't.
I have a normal ubuntu install, I use the i3wm to reduce general load. Resolution set to 1440p with xrandr, no scale adjustments. GPU disabled, totally on intel graphics.
My xps is about 4.5 years old right now, I have replaced the battery when it started to swell slightly, the replacement was salvaged from another and even worse, so after a year I put the original battery back in.
I honestly think the biggest thing is a tiling wm. Any time I go from full gnome to i3wm, my battery life gets an instant 3 hour bonus.
Big ole note, because of the age and battery degradation, i can squeeze about 6-7 hours out of with if I limit myself to a single firefox window and text editors. When it was brand new, 13 hours of normal use was totally doable.
