by | Jan 8, 2024

Apple’s MacBook lineup is well-known for its long-lasting battery life. According to Apple, all models promise around 10 hours of usage. However, there are certain conditions and limitations involved. If you want to make your MacBook Pro or MacBook Air’s battery last even longer, here’s a helpful guide to follow. To give credit to Apple, the company has implemented some battery-saving measures to maximize the battery life on MacBooks and MacBook Pro models. As a user, you have the ability to adjust certain settings in macOS to get the most out of your MacBook’s battery. In this post, we will discuss some of the best tips and tricks to save and improve MacBook’s battery life and extending the usage time of your MacBook Air or MacBook Pro. Let’s begin!

How to Improve MacBook’s Battery Life

1. Check Battery Health

To make sure your MacBook’s battery is in good condition, it’s important to keep an eye on its health and performance. This will help you understand how well your battery is functioning and if any actions need to be taken.

Here are two things you should check:

  • Cycle Count: This tells you how many times your battery has been charged and discharged. Generally, it’s better to have a lower cycle count because it means your battery has been used less.
Check Battery Health
  • Condition: This shows you the overall health of your battery. If it says “Normal,” that means your battery is in good shape. But if it says something other than “Normal,” it might be a sign that your battery is not performing as well as it should and you might need to replace it.

By keeping an eye on these indicators, you can monitor your battery’s health and make informed decisions about how to take care of it.

2. Keep macOS Updated

It’s important to make sure your system is always up-to-date. Apple regularly releases updates that improve the battery efficiency and overall performance of your Mac.

  1. Follow these steps to update your macOS:
  1. Start by clicking on the Apple Menu at the top and opening System Preferences.
  1. Look for the option called “Software Update” and click on it.
  1. Wait for your system to search for available updates. Once it’s done, click on “Update Now.”
Keep macOS Updated

Please note that the update process may take some time, depending on the size of the update. It’s worth the wait to ensure that your Mac is running on the latest software with the most recent optimizations and improvements.

3. Avoid Using Chrome Browser

Google Chrome is a popular web browser, but it’s also known for using up a lot of system resources and draining your battery quickly.

In these situations, it’s best to consider using the Safari browser instead. Safari is specifically optimized for MacBooks and can help conserve your battery life. Alternatively, you can also try other browsers like Microsoft Edge, which work well on various platforms. By using a browser that is less demanding on your system resources, you can reduce the strain on your battery and improve its overall lifespan.

4. Turn on Optimized Battery Charging

The Optimized Battery Charging feature on macOS is designed to help prolong the overall lifespan of your MacBook’s battery by reducing the wear and tear caused by constant charging to 100%.

Here’s how you can enable it:

  1. Start by clicking on the Apple menu on your desktop.
  1. Open System Preferences.
Turn on Optimized Battery Charging
  1. Scroll down and click on Battery in the left sidebar.
  1. Next to Battery Health, click on the (i) icon.
  1. Then, enable Optimized Battery Charging.
Turn on Optimized Battery Charging
  1. Click on Done to save the settings.

Once you have enabled this feature, your Mac will charge up to 80% quite quickly. After studying your charging patterns, it will then postpone charging to 100% until it predicts that you will unplug it and start using it again. By doing this, it helps protect your battery’s health and maximize its longevity.

5. Use Auto Brightness

Enabling Auto Brightness is a great way to save your MacBook’s battery power and reduce strain on your eyes over time. The screen is one of the components that consumes the most power, so lowering its brightness can help conserve battery life.

  1. Once again, click on the Apple Menu and open System Preferences.
  1. Click on Display in the left sidebar.
  1. On the right, enable the option for Automatically Adjust Brightness.
 Use Auto Brightness

By enabling this feature, macOS will continuously adjust the screen’s brightness to an appropriate level, preventing excessive power consumption. This not only helps prolong your battery life but also ensures a comfortable viewing experience for your eyes.

6.Turn Off Keyboard Backlight

Just like we enabled auto brightness for your display, we can do the same for your keyboard backlight. By controlling how the keyboard lighting behaves, you can save your Mac’s battery life.

Here’s how you can do it:

Turn Off Keyboard Backlight
  1. Start by clicking on the Apple menu at the top-left corner and opening System Preferences.
  1. Scroll down and click on Keyboard in the left sidebar.
  1. In the Keyboard settings, enable the option for “Adjust keyboard brightness in low light.” Then, you can manually lower the keyboard light or even turn it off completely.
  1. Additionally, you can adjust the timing for “Turn keyboard backlight off after inactivity.” You can choose a specific time from the provided list.
  1. By adjusting these settings, you can conserve your battery power by reducing unnecessary keyboard backlight usage.

And wait, there are more ways to help improve your MacBook’s battery life. For instance, there are battery apps available that can further optimize your battery usage.

7. Maintain a Cool Temperature for Your MacBook

MacBooks perform best when kept within an optimal temperature range of 50° to 95° F (10° to 35° C), according to Apple’s guidelines. Exposing your device to extreme temperatures, especially above 95° F (35° C), can significantly impact its battery life.

To ensure your MacBook stays cool, follow these tips:

Maintain a Cool Temperature for Your MacBook
  1. Ensure proper ventilation: Avoid using your MacBook on soft surfaces like beds or couches, as they can obstruct airflow if your Mac has vents. Some models, like the MacBook Air, don’t have vents. Instead, place your MacBook on a solid table or desk where air can circulate freely.
  1. Consider using a cooling pad: If you find that your MacBook tends to get hot during extended periods of use, you can purchase a cooling pad. These pads help dissipate heat and keep your MacBook’s temperature in check.

By maintaining a cool temperature for your MacBook, you can help optimize its performance and preserve the lifespan of its battery.

8. Close Unnecessary Apps Running in the Background

Apps running in the background can use up a lot of power without your knowledge. To save battery life, you can close apps or functions that you’re not currently using.

Here’s how you can manage background apps on your MacBook:

  1. Press the Spacebar and Command keys together to open Spotlight Search.
  1. Type “Activity Monitor” and open it from the search results.
  1. In Activity Monitor, check the CPU and Energy columns to identify which apps are using the most resources.
  1. Select apps that you’re not actively using and can close. To do this, click on the “x” at the top to quit those apps. Be cautious and only close apps you recognize and are comfortable with, avoiding system apps or unfamiliar app/process names.

By closing unnecessary apps running in the background, you can conserve your battery and ensure that power is dedicated to the tasks you’re actively working on.

9. Disconnect External Devices

When you’re not using them, make sure to unplug any external devices such as external hard drives, USB devices, or accessories from your MacBook. These peripherals can drain power from your MacBook even when it’s not in use, which can affect your battery life.

Some of these devices even have LED lights that consume battery power, as we discussed earlier.

10. Turn off Apps that Start with Your MacBook

When you start up your MacBook, all the apps that are set to open automatically also start up at the same time, even if you don’t plan on using them right away. This can make your MacBook take longer to boot up. Additionally, these startup apps use up system resources like CPU and RAM, which can slow down the initial performance of your laptop.

This can have an impact on your battery health every time you start your MacBook. However, you have the option to disable these startup apps:

Turn off Apps that Start with Your MacBook
  1. Click on the Apple menu at the top and open System Preferences.
  1. Click on General in the left sidebar.
  1. Then, open Login Items on the right.
  1. Look at the list under “Open at Login.” Select the app you want to exclude from the list and click on the “-” button below.
  1. You can also disable certain background items from operating while your system is running by removing them from the “Allow in Background” list.

By disabling unnecessary startup apps, you can reduce the time it takes for your MacBook to start up and improve its overall performance. This, in turn, can help preserve your battery life.

11. Disable Wi-Fi and Bluetooth

Having Wi-Fi and Bluetooth enabled on your MacBook can consume power and affect your battery life. When your MacBook is actively using Wi-Fi to browse the web, stream videos, download files, or perform other network-related tasks, it uses up power. Similarly, Bluetooth can also drain your MacBook’s battery.

To save battery power, you can turn off Wi-Fi and Bluetooth when you’re doing offline tasks such as reading ebooks, playing offline games, watching downloaded movies or shows, or working on office documents.

Here’s how you can do it:

Disable Wi-Fi and Bluetooth
  1. Go to the Control Center located at the top-right corner of your screen.
  1. Click on the Wi-Fi and Bluetooth icon and switch them off.

12. Turn Off Turbo Boost

Turbo Boost is a feature that makes your Mac’s CPU run at higher clock speeds to improve performance, but it only does so temporarily. However, it’s not always necessary to have Turbo Boost enabled because it can use more power than usual. 

Turn Off Turbo Boost

While you can’t control Turbo Boost directly from the system settings, there are third-party apps like Turbo Boost Switcher that you can use to manage it. It’s important to note that this feature is only available for Intel-based MacBooks.

Before you proceed, you need to check if your MacBook supports Turbo Boost technology. To do this, click on the Apple logo at the top left corner of your screen and select “About This Mac.” Copy the first line of information and paste it into a Google search box, adding the word “specs” at the end. Look for the search result that starts with “https://support.apple.com” and click on it. On the page that opens, check under the “Processor” section to see if Turbo Boost is mentioned. If it is, you can continue reading.

Here’s how to enable or disable Turbo Boost on your MacBook:

Step 1: Download Turbo Boost Switcher.

Step 2: Once downloaded, extract the ZIP file and run “Turbo Boost Switcher.app.”

Step 3: If you encounter an error about an unidentified developer, go to System Preferences, then Security and Privacy, and click on “Open Anyway.”

Step 4: After the app launches, you’ll see a thunder-like icon in the Status Bar. Click on the icon and select “Disable Turbo Boost” from the drop-down list.

That’s it! Turbo Boost is now disabled on your MacBook. If you want to enable it again, repeat the last step and select “Enable Turbo Boost.”

13. Connect Your MacBook to Power When Charging Other Devices

When you’re charging your iPhone or any other device using your MacBook, make sure that your MacBook is also connected to a power source. This way, you can prevent your MacBook’s battery from draining while charging external devices.
