Call me crazy, but most people working typically leave their laptops wired in to either a charger or a hub so they can have more monitors. I know some people will go through the effort of charging and pulling the cord, and charging later, but most people don't want to micromanage something they can forget about while working. If you're living on battery life for a work call, it would not matter if you're on Windows, changes are high your batterly life will self-terminate quicker than you realize.
