Tricks for getting more hours from a MacBook Pro battery

My job often requires me to work for many hours at an unplugged laptop. I’ve picked up a few tricks for making the battery last longer. None of these are particularly brilliant, but they’re very helpful:

  • Turn off WiFi. That’s a big battery suck right there. In practice, I end up turning it on again briefly if I need to check something, then turning it right off again.
  • Likewise, dim the screen as far as I can still read it. That’s one or two ticks up from completely dark.
  • When I’m not typing, I shut the screen off manually. I close the lid if I think it’s going to be a while, and for short periods I have a hot corner set up to shut off the screen when I move the mouse to the bottom right corner.
  • Use Activity Monitor to find which apps are using the most energy and shut them down. For me, that’s Google Chrome and Microsoft Teams.

By taking these four measures, I was able to get about nine hours’ usage out of my MacBook Pro on Monday.

Do you have any tricks for getting more out of a laptop battery? I’m told shutting off Bluetooth helps, but in practice I haven’t found it to matter much. And I’m also told that Chromebooks can easily get 10+ hours of battery life without having to do any tricks at all.
