I recently bought an external monitor so i can use it in clamshell mode. I use it for around 10 hours a day. So, what is the safest way to use it so i don’t ruin the battery health? Is it ok to always leave it plugged in all the time? I think these are the ways how people use clamshell mode. I was wondering which would be the better way ?

  1. powering both macbook and monitor separately (140W power brick)
  2. powering monitor and charging macbook via USB C (max delivery 80W)
  3. powering monitor and charging macbook only when required using Amphetamine. (140W power brick)
