When I was in the office full time in the bad old days, you would be in a conference room and every one would plug their laptops in.
After I started working remotely and still doing business trips, one charge could last a full day either going back and forth between conference rooms, in “war rooms” etc and no one with M series MacBooks even worried about charging.
Heck my MacBook Pro (work laptop) can last a full day on power with my portable USB C powered external monitor where the power and video come from one cord.
Not to mention on flights with layovers.
I used to run Linux on a laptop (10+ years ago) and you couldn't even close the laptop lid without risking it not going to sleep and overheating in your bag.
I don't worry about closing my thinkpad lid. Well I do because I disable sleep on lid close and prefer using the dedicated button for that. But my thinkpad goes to sleep when I ask it to.
