I believe you (and Apple) that the battery can be charged faster, but I am currently rendering video on an M1 MBP. Its power draw: ~20 Watts. That's a lot of charging overhead.

The 16” has a 100wh battery, so it needs 100w of power to charge 50% in 30 minutes (their “fast charging”). Add in 20w to keep the laptop running at the same time, and some conversion losses, and a 140w charger sounds just about right.

That actually sounds on the money. I hope you're right!
