Considering a laptop can be at most 100Wh for US air travel - I doubt you'll see 50 hours anytime soon. That would mean the display is drawing less than 2 watts

Considering a laptop can be at most 100Wh for US air travel - I doubt you'll see 50 hours anytime soon. That would mean the display is drawing less than 2 watts of energy while the rest of the system is near 0. Typical displays apparently use 2 watts - https://www.digitaltrends.com/computing/intel-low-power-display-technology/ https://www.digitaltrends.com/computing/intel-low-power-disp... If Intel released a 1-watt display then we might see the 50-hour level reached but that's going to only be on really light workloads. (Light text editing?
