Has anyone noted in a review or from their own behavior the impact from screen brightness when quoting such long run times on a single charge for the new M1 MacBook Air/Pro? Like for my iPhone, iPad, and 2014 MacBook Air, screen brightness has perhaps the biggest effect on power consumption.
 
From www.apple.com/macbook-air, under "18 hours of battery life" section:

Testing conducted by Apple in October 2020 using preproduction MacBook Air systems with Apple M1 chip and 8-core GPU, configured with 8GB of RAM and 512GB SSD. The Apple TV app movie playback test measures battery life by playing back HD 1080p content with display brightness set to 8 clicks from bottom. Battery life varies by use and configuration. See apple.com/batteries for more information.
