If there’s one thing you want from a laptop, it’s long battery life. You want every drop of power you can get to work, read, or just be entertained on a long jaunt. So it’s good to know where your power is going.
You can use the powertop utility to see what’s drawing power when your system’s not plugged in. This utility only runs on the Terminal, so you’ll need to open a Terminal to get it.
