How Does Low Power Mode Work on Mac

Low Power Mode is a battery-saving feature on MacBooks that reduces energy use to increase battery life. When you use Low Power mode on a Mac, macOS alters the following features:

• Reduces the brightness of the display.
• Decreases CPU clock frequency.

In addition, this feature makes your MacBook run cooler and quieter than before. Also, it might disable some background processes and affect the transfer speeds as well. For instance, you might experience slower AirDrop transfers.

We all use Low Power mode on iPhones and iPads that’s designed to save battery life by limiting or disabling some features. Mac’s Low Power mode is the macOS-optimized version of the same feature.

Mac Low Power Mode Requirements

• Low Power mode is available on MacBook Air and MacBook Pro models launched in 2016 or later.
• It’s not available on desktop-based Macs like iMac and Mac mini.
• Your MacBooks must be running on macOS 12.0 Monterey or later software versions.

How to Enable Low Power Mode on a Mac

Now that you know what Low Power Mode means and does to your Mac, you should know how to enable it. Move along, here’s how you can enable Low Power Mode on your Mac to reduce battery usage:

Tip: A quick way to access the Battery section on Mac is to click on the Battery icon from the Menu bar and choose Battery Settings.

• From the top-left of your Mac’s display, click on the Apple Menu and choose System Settings. Alternatively, open the System Settings app from the Dock.

• From the left sidebar, visit the Battery section. This will bring up Battery settings on your Mac.

• Now, click on the drop-down menu next to Low Power Mode.
• You’ll see four options: Never, Always, Only on Battery, and Only on Power Adapter. By default, the Never option is selected.

• When you choose “Always”, your Mac will always stay in Low Power Mode. The “Only on Battery” option ensures that Low Power Mode is enabled when it’s running on the battery. In both cases, your Mac will reduce energy consumption to save battery life. If you go for the “Only on Power Adapter” option, the battery-saving feature is enabled when your Mac is connected to a power source. It will automatically manage performance to reduce energy usage.

To verify that your Mac is running on low power mode, click on the Battery icon from the top right of the screen. Here, you’ll see “Low Power Mode: On”.

When You Should Use Low Power Mode?
