Set “Turn Display Off After” to 2 minutes (on the Battery tab).Enable the checkbox for “Automatic Graphics Switching,” which uses the more energy-efficient built-in graphics as much as possible.

Next up is the Energy Saver System Preferences pane, where I: Because the display consumes a lot of power, I disable “Automatically Adjust Brightness” and slide the brightness control to the lowest setting I can tolerate. My first stop is the System Preferences app’s Displays pane. So, when I’m running on battery power, I have a bag of tricks for preserving battery life. And while I used to routinely get 5 or 6 hours, today I only get about 4 hours, and that’s if I’m lucky. I know that battery performance degrades over time. So, I started looking for ways to eke out more battery time from the 7-year old MacBook Pro.

But I’m not jealous enough to drop $3,000 on a new MacBook Pro just yet. That’s enough to work all day without AC power. When it was new, 5 or 6 hours of battery life was the best you could expect from this class of laptop, but the newest 16-inch MacBook Pro boasts of up to 11 hours of battery life between charges. That its processor, memory, and storage are still sufficient for my needs 7 years later is impressive, but there is at least one thing I’d love to change if I could… and that’s its battery life. With its 2.6 GHz Quad-Core Intel Core i7 processor, 16GB of RAM, and 1TB SSD, it’s got (almost) everything I need and I expect it to last a few more years before it becomes outdated or dies. My 15-inch MacBook Pro is 7 years old and it still runs like a champ.
