9 Ways to improve MacBook battery life

There are many ways to enhance MacBook battery life. These practices also help increase the battery backup. The suggestions below will help squeeze the most out of your MacBook battery.

1. Switch to Safari

Using Safari on Chrome can have a significant impact on battery life. Chrome is notorious for hogging system memory. Safari is frugal and a better choice for those in the Apple ecosystem. It offers iCloud integration, password manager, reading mode, and Continuity features.

Switching to a new browser is not easy, but give it a try.

Apple has added a new Battery Health management feature starting with macOS Catalina. The feature uses power consumption data to optimize the charge cycle.

In other words, the battery will only charge to an optimized level based on your usage. It will help prolong battery life by reducing wear and chemical aging.

3. Update MacBook and apps

A newer version of the operating system offers better battery management features. Consider updating your MacBook to macOS Monterey. Update current apps to the latest version.

4. Ensure airways/ventilation is not obstructed

MacBook can turn excessively hot when placed on a cushion or sofa. This is because air cannot circulate and dissipate heat. Keep your MacBook on a flat surface. Alternatively, you can use a laptop stand.

Avoid storing your laptop directly under sunlight, especially when you keep it inside a car.

5. Enable auto-brightness and turn off the keyboard backlight

Automatic brightness is enabled by default on new MacBooks. It helps conserve battery levels by automatically changing brightness with respect to ambient conditions. Follow the steps below to enable the auto-brightness feature.

  1. Click the Apple logo → open System Preferences.
  2. Select Displays.
  3. Check Automatically adjust brightness.

7. Clean up your Mac

Over some time, MacBook gets cluttered with redundant files. These files slow down your system. It is always a good idea to weed out such clutter. I suggest taking the help of third-party Mac cleaner apps.

8. Disconnect charger when fully charged

Some of us have this nasty habit of keeping the charger plugged in. The resulting heat can degrade the battery. In other words, unplug your laptop and let the power drop to 40-50%. Make sure the battery is not exposed to high temperatures.

9. Use M1-optimized apps

Universal apps are those that run on both Intel and M1-based Mac. If you own an M1 (or M1 Pro/Max) powered Mac use universal apps. Also, check out these best tips to increase battery life on M1 MacBook.
