How to Save Your MacBook’s Battery Power

Here are over forty ways to increase the battery life of your MacBook Air or MacBook Pro with an Apple silicon (M1, M1 Pro, M1 Max) or Intel processor, running any recent macOS version, including the current macOS Monterey.

With the help of these battery tips, you should be able to use your MacBook for a longer time on a single charge. It’s important to note that while these suggestions are helpful for all, you should make sure to follow only those you’re comfortable with or those that aren’t getting in the way of your productivity and workflows.

1. Lower the screen brightness

Your MacBook screen uses a lot of battery when it’s on full brightness. To ensure you can use your MacBook for a longer time per charge, make sure to reduce the screen brightness.

You can do that by:

  • Using the key on the top row of your keyboard
  • Using the brightness icon in the Touch Bar
  • From the macOS Control Center in macOS Big Sur and later
  • Asking Siri to lower the brightness
  • Going to System Preferences > Display

Button on Touch Bar to decrease brightness. The corresponding key on MacBook’s built-in keyboard has the same dim sun icon.

2. Use auto-brightness

Auto-brightness adjusts your MacBook’s screen brightness based on the light around you. It’s an indispensable setting that automatically lowers the screen brightness when required, thus extending the battery life. Auto-brightness is enabled by default. Still, click  > System Preferences > Display to ensure you haven’t turned it off.

3. Use Hot Corners to turn off MacBook screen

On my Mac, I have set the bottom right Hot Corner to put the display to sleep. Whenever I’m about to move away from my desk to drink water, go to the washroom, or just straighten my body for a couple of minutes, I drag the mouse pointer to this corner of the screen, and it turns off the display instantly. To set up Hot Corners, go to System Preferences > Mission Control > Hot Corners.

4. Disable keyboard backlight

To save your MacBook’s battery, turn off the keyboard light or set it at the minimum level. For this, use the keyboard brightness key on the top row of the built-in keyboard or the Touch Bar.

Button on Touch Bar to decrease keyboard backlight level.

You can also go to System Preferences > Keyboard and enable Adjust keyboard brightness in low light and Turn keyboard backlight after 5 seconds of inactivity.

5. Quit apps you aren’t using

Suppose you open a Mac app, use it for a minute, and then won’t be needing it for several hours. To extend your battery life, you should close such apps.

6. Limit the number of browser tabs

To increase MacBook’s battery life, close browser tabs you no longer need. Plus, instead of opening several tabs with the prospect of seeing them in the next few hours, open just a few, use them, and close them before opening new tabs.

7. Enable Low Power Mode

Low Power Mode on macOS Monterey lets you increase the MacBook’s battery life and help operate it more quietly. To enable Low Power Mode on MacBook, go to System Preferences > Battery and check the box for Low power mode.

8. Use the right battery settings

Your MacBook has a few handy battery tricks to help you get more hours on a single charge. Go to System Preferences > Battery and:

Set Turn display off after a brief period of inactivity. I keep it at 2 minutes.

Slightly dim the display while on battery power

Optimize video streaming while on battery

On old versions of macOS, go to System Preferences > Energy Saver > Battery.

9. Keep Optimized Battery Charging turned on

Regularly going to extreme ends (0% charge or 100% charge) puts significant stress on the lithium battery of any device. So, to ensure your device’s battery has a longer lifespan, avoid fully discharging and fully charging it with every use.

Just like iPhone, Apple Watch, and even AirPods, new macOS versions offer Optimized battery charging on MacBook that reduces battery aging by learning your daily charging habits and waiting to finish charging past 80%. It’s enabled by default, and you shouldn’t turn it off. You can see it under System Preferences > Battery.

On slightly old versions of macOS, you might not see Optimized battery charging. In that case, click Battery Health and make sure Manage battery longevity is enabled. On even older versions of macOS, you may not see this as well. So, follow the next suggestion.

10. Don’t keep your MacBook plugged in all the time

As mentioned in the above heading, you should avoid charging and discharging the battery to extreme ends. While in the office or working from home, when you aren’t doing any heavy task, unplug the MacBook’s charger and use it on battery.

That being said, don’t overthink this too much. Just keep this fact in mind, and when possible, try to disconnect the charger.

11. Plug your MacBook during intensive tasks to reduce load on battery

When you’re working on battery-hogging tasks like video exporting, 3D modeling, video compression, etc., make sure your MacBook is connected to power. This will reduce the strain on the battery during that time.

12. Use apps optimized for Apple silicon

Thanks to Rosetta 2, applications developed for Intel Macs run smoothly on Macs with Apple silicon (M1, M1 Pro, M1 Mac, and its successors).

As per Apple, “In most cases, you won’t notice any difference in the performance of an app that needs Rosetta.”

But to get the best battery life and an optimal experience on your M1, M1 Pro, or M1 Max MacBook, try to use the Apple silicon version of apps when available. For example, while downloading Edge and other apps, you might see two versions – one optimized for Apple chip and the other for Intel Macs. Make sure you choose the right one.

For apps you have been using for a long time, go to their website and see if an Apple silicon version is now available or not. You can also contact the app developer to enquire about Apple silicon support.

In case you find that an app isn’t optimized for Apple silicon and uses more battery (or causes other trouble), try to look for an alternative.

13. Regularly restart your MacBook

Make it a habit of turning off your MacBook and turn it back on every few days.

14. Shut it down at night

Even with the lid closed, if MacBook is powered on, it will use some battery. If your workflow permits, try to power off your MacBook every night.

15. Download videos instead of streaming

Streaming videos take a toll on your battery. When you’re going out or traveling, instead of using the airport or railway station Wi-Fi to stream videos, make sure you download them beforehand onto your MacBook.

16. Limit the number of connected accessories

Are you using several accessories with your Mac like pen drives, external SSD, portable hotspots, heavy speakers, and such? If yes, disconnect them to increase the battery life.

17. Eject CD and DVD on old MacBooks

If your old MacBook has a disk drive, make sure you haven’t left any CD/DVD in it.

18. Plug to power when you connect an external display

When you use an external monitor with your MacBook, make sure your notebook is plugged into charging. For future purchases, try to buy a monitor that can charge your MacBook with the same display cable.

19. Plug your MacBook when charging connected devices

If you charge your iPhone, iPad, iPod, or other such small devices via your MacBook, make sure the MacBook itself is plugged into charging when these mobile devices are connected to it.

20. Take note of your MacBook’s temperature

Is your MacBook’s fan spinning loudly and the base of your machine too hot? This can frequently happen during heavy tasks like video editing. In this situation, quit unnecessary apps, limit multitasking, and once your work is done, give your MacBook a break and give it the time to cool down.

Be mindful of the fact that extreme temperatures (too hot or too cold) aren’t suitable for any electronics. On MacBook, it can harm the internal components like the motherboard or battery.

21. Update your Mac to the latest macOS version

If you’re on an older version of macOS, go to System Preferences > Software Update and get the latest available macOS.

22. Update third-party apps

An app that isn’t updated may not be optimized for the latest macOS version. It may crash, consume more battery, and offer a poor experience with fewer features. To fix these, update the app from the Mac App Store or look for a “Check for updates” button in its preferences (accessed by pressing Command + Comma (,)).

23. Prefer earphones over MacBook’s speakers

I love my MacBook’s incredible built-in speakers. But it utilizes a significant amount of battery. So, when low on power, try using wired earphones with your MacBook.

24. Remove unnecessary apps

I have a MacBook with Apple silicon. I have noticed that iPhone and iPad apps installed on my Mac run even when the app isn’t open. For example, the Alarmy app (to set alarms on Mac) will trigger the alarm even when the app is closed. So, if you have several similar apps on your Mac that you don’t need, make sure to uninstall them.

25. Stop using a screen saver

On a Mac desktop, which is connected to power, the screen saver looks nice. But on a MacBook, for the most part, it’s unnecessary as keeping the display active uses a battery. Therefore, go to System Preferences > Desktop & Screen Saver > Screen Saver and uncheck Show screen saver after.

26. Use a still wallpaper instead of one that cycles through

You can use a feature called Dynamic wallpapers on modern macOS versions. Based on the time of the day and your location, it changes the desktop wallpaper throughout the day. While the feature is nice, turn it off if you want to go stringent on battery life. Secondly, make sure you do not put extra stress on your computer by asking it to change the picture every few minutes.

You can access Dynamic and changing wallpaper in Mac’s System Preferences > Desktop & Screen Saver > Desktop. Now, click the Dynamic dropdown menu and select Still. If you aren’t using Dynamic wallpaper, make sure the box for Change picture [every 30 minutes] is unchecked.

27. Disable Wi-Fi, Bluetooth, and AirDrop when not in use

Suppose you’re watching a downloaded movie on your Mac or listening to some local tunes. If you don’t need Wi-Fi, turn it off. Similarly, turn off other wireless features like Bluetooth and AirDrop.

On macOS Big Sur and later, you can find all these in Control Center. On older versions:

Turn off Wi-Fi from System Preferences > Network > Wi-Fi > Turn Wi-Fi Off.

Turn off Bluetooth from System Preferences > Bluetooth > Turn Bluetooth Off.

Disable AirDrop visibility from Finder > AirDrop > Allow me to be discovered by No One.

28. Prevent apps from launching automatically on startup

Do several apps start jumping in the Dock and open automatically when you switch on your MacBook? If yes, these app launches may consume a tiny bit of battery. So, make sure you only have no more than one or two apps to launch automatically at login. For the rest apps, stop their auto-launch privilege.

29. Turn off notifications for unnecessary apps

Go to MacBook’s System Preferences > Notifications & Focus > Notifications > select an app and turn off the Allow Notifications toggle.

In the future, when you install apps and they ask for your permission to send notifications, be a miser. Allow only essential apps to notify you.

30. Change Mail app’s fetch settings

Do you use your Mac’s built-in Mail app? To save battery, open Mail > press Command + Comma (,) > General and set Check for new messages to fetch manually instead of automatically.

31. Remove unnecessary accounts

You can add iCloud (obviously), Google, Outlook, Yahoo, and other accounts to your Mac for Mail, Notes, Contacts, etc. If possible, remove the unnecessary ones. If you ever wish to access these email accounts, use them in a browser.

To remove accounts on your Mac, open System Preferences > Internet Accounts > select the account and click the small minus icon.

32. Use Safari instead of Chrome

Despite Chrome now being more battery-friendly, using the built-in Safari can positively affect your MacBook’s battery.

33. Disable location for unnecessary apps and websites

Go to System Preferences > Security & Privacy > Privacy > Location Services. Now, click the lock icon from the bottom left and authenticate via your Mac’s password or Touch ID. From here, I wouldn’t recommend unchecking the Enable Location Services box. But what I would wholeheartedly recommend is to uncheck location access for unnecessary apps. This is good for privacy and battery life.

Some websites (like weather, bank, food delivery) require your location. So, either you can type your location manually. Or permit only the necessary websites to use your location. While doing that, check the handy “Remember my decision for one day” box.

After your work is done, press Command + Comma (,) to go to browser preferences and deny the location access from there.

34. Free up space on your MacBook

To keep your MacBook in perfect standing, make sure you delete unnecessary files from it. After cleaning the unwanted files, don’t forget to empty the trash.

35. Prevent Spotlight from indexing certain folders

If you have a folder where you create and delete files on a daily basis, you can ask Spotlight not to index files in this location. This reduces the indexing work of Spotlight, thus consuming less battery.

36. Use Activity Monitor to see battery hogging apps

The Energy tab of MacBook’s Activity Monitor gives you information about apps using batteries, the ones that are preventing your computer from sleeping, and more. Use this to find apps consuming the most power and quit them if needed.

37. Disable Turbo Boost

On supported Intel Macs, your computer can use Turbo Boost when the CPU requires extra power. Some apps like Photoshop may force your Mac to Turbo Boost using more battery.

38. Reset SMC on Intel MacBook

If energy problems like incorrect battery percentage continue on your MacBook, reset the System Management Controller (SMC).

39. Keep track of your battery percentage

To know precisely about the remaining battery on your MacBook, go to System Preferences > Dock & Menu Bar > Battery and check Show in Menu Bar and Show Percentage. If you notice that your MacBook’s battery is about 20% or 30%, you can stop playing games and streaming videos to preserve power for important work.

40. Use the original charging plug and cable

For the best battery life on your MacBook, make sure you use the original charger and cable that came with your machine. If it no longer works, buy one from Apple or a reputable manufacturer (after doing diligent online research and reading reviews).

41. Check your MacBook’s battery cycle count and battery condition

No matter how many precautions and battery-saving tips you follow, if your MacBook is old and its battery has degraded, it won’t offer a long use time. One such factor that helps you know your MacBook’s battery status is cycle count.

42. Replace your battery

When you click the battery icon in the menu bar, does it say “Service Recommended“? If yes, take your old MacBook to an Apple Store or an Apple-authorized service center and get the battery replaced. A new battery will allow you to use it for more hours per charge.

Battery life is related to how you use your MacBook

These were almost all the battery-saving tips you can follow on your MacBook. As mentioned, I don’t recommend you implement them all at the same time. But, it’s nice to know these and use them when required.

That being said, how much time you get on each charge depends on what you’re doing. So, when you know that you would not get the opportunity to charge your MacBook for a while, try to cut down unnecessary and unproductive tasks.
