Laptops and screens can be pretty efficient. I got a pretty cheap run of the mill one (Arch btw) that easily does >8 hours at full blast HDR and no power saving.
I gotta add to this the app Brightintosh. It kicks up the screen brightness to the actual max brightness of the screen so a good 2x brighter. Major dif using in bright environments, less screen life and color accuracy theoretically
