Battery Saving Tips for Your MacBook

Happy MacBook owners appreciate the possibility to work on their devices without any need to look for a power socket. A brand new MacBook battery typically lasts several hours. Unfortunately, sooner or later you’ll notice a decrease in battery performance.

How to handle MacBook properly and save precious minutes or even hours of battery life? You’ll find useful information and battery saving tips in this article.

Apple manufactures laptops with battery cycles limit from 300 to 1,000. It means that your MacBook may use all of its battery power from 300 to 1,000 times. When the charge cycle limit is reached, your machine starts to act up. In such case there’s nothing strange in unexpected Mac shutdowns or battery life reduction.

Warned means armed, and knowing how many charging cycles remain may help you determine when it’s time to replace the battery.

To check the battery condition:

  1. Click the Apple logo.

  2. Hold down the option key and select System Information.

  3. In the Hardware section, click “Power”.

  4. Under Health Information, check the cycle counts and condition of the battery. 

5 Steps to Increase the Battery Life

1. Energy saver and system updates.

System updates are always released to fix minor bugs and improve battery life or eliminate the battery killing processes. To install the latest updates, click the Apple logo and choose software updates (App Store in the newest OS X).

Energy saver is your best friend if you own a Mac laptop. Open System Preferences and click the Energy Saver tab. Here you can control your display power settings. You can  use several tricks here, specifically, “Turn the display off after”, “Put hard disks to sleep when possible,” and “Dim the display while on battery power”.

2. Turn off unnecessary features and dim the display.

Reducing or turning off the macOS features can spoil your Mac experience, but at least you’ll “squeeze” some life out of your battery. The first thing to try is to reduce screen brightness. To do this, navigate to System Preferences and dim the screen.

Turning off the Bluetooth (if it’s not necessary at the moment) saves a few minutes of battery work on your machine. Open System Preferences, choose Bluetooth, and then turn it off.

If you are using your Mac offline, active Wi-Fi is not necessary. If this option is turned on, the user can easily deactivate it via the Network tab in System Preferences. How it can help to save you battery time? If the Wi-Fi signal is poor, more power is required to transmit or receive data. If there is no access to wireless network and this option is active, your device is constantly searching for it. This causes battery drain.

3. Battery eaters and “runaway” processes.

Very often certain processes can affect your Mac performance and battery runtime. You can easily identify and eliminate these battery killers in the Activity Monitor. Go to the Applications/Utilities folder and open the Activity Monitor app. In the application window, click the Energy tab. You’ll see the list of active processes and their energy impact. If the application consumes too much battery energy, consider uninstalling such application or contact the customer support. Very often app developers release patches to fix such issues. It’s also a good way to check how much battery life is taken by all apps that are installed on your Mac.


Choose the CPU column and check which processes take up more than 70% of CPU. Select such process and click the quit icon to close it. You can find more information and workaround here: https://support.apple.com/en-us/HT203184


4. Remove unnecessary peripherals and accessories.

Removing peripherals and disconnecting unnecessary cards, drives and modems will help your laptop to run for a little bit longer. It’s also a good idea to eject a CD/DVD.

5.  Avoid gaming and 3D graphic apps.

It’s not a secret that if you want to squeeze extra minutes of battery life out of your machine, you should avoid gaming and “graphics-heavy” apps. 3D design, graphic apps and games overload the processor and eat up battery power. If you have electricity cut off and need extra minutes of autonomous work on your machine, avoid such things.
