Learn how to enable the Low Power Mode feature on your MacBook Air or MacBook Pro laptop to extend battery life and help it run cooler and quieter.

What is Low Power Mode?
Low Power Mode is a battery-saving feature available on Mac notebooks manufactured in 2016 or later and running macOS Monterey or later that helps increase battery life by reducing display brightness, decreasing the CPU clock frequency, and temporarily suspending some background activity.
Underclocking the CPU and dimming the display helps extend battery life, but the machine won’t run as smoothly as before, and you may notice some choppiness.

When should you turn on Low Power Mode?
Low Power Mode offers a trade-off between performance and energy consumption. To help lower energy consumption, Low Power Mode reduces system performance which will make your Mac run slower.
You won’t notice a significant performance drop in performance in everyday usage if all you do on your Mac laptop is read news sites, check email, use social media, and so on. These are typical use cases for Low Power Mode. This feature is also available on the iPhone, iPad, and Apple Watch.
