18 Ways to Improve Your MacBook’s Battery Life


Your Macbook is a great investment for anyone who needs to stay productive while on the go. While many people fear that mobile devices cannot provide the same productivity as their desktop counterparts, this is not true with today’s modern Macbooks and Macbook Airs. There are several things you can do to ensure that your battery life lasts as long as possible.

1) Dim Your Screen:  You might think that if you need your screen brighter in order to see what you’re doing, then it would be better if the screen was always bright. However, your display uses up a large amount of power. The best way to save power when using your laptop at home or in the office is to simply turn down the brightness whenever you don’t need it at its full brightness.


2) Turn Off Bluetooth:  In order to easily transfer files from your mobile devices, it is not uncommon for a laptop user to have their Bluetooth turned on all the time. However, this also causes your battery to drain more quickly by using up power that could be saved for when you need it. You can simply turn off bluetooth whenever you don’t need it and then turn it back on when needed again – easy as that!

If you really need Bluetooth, then quickly turn it off after connecting and taking the file or whatever the task is for which you activated Bluetooth in the first place. If all you’re doing is browsing the web and checking email, then disable Wi-Fi since it uses more power than just plain old Ethernet (unless your office already has free WiFi.) And lastly, if you do not use Time Machine on a regular basis, turn it off completely since this feature will always be working in the background even if you never click on any of its preferences.

3) Close Unnecessary Applications:  A perfect example of why closing applications after they are done being used is because many programs open web connections that remain open even if the program itself is no longer running. For instance, some news agencies will keep their webpage open for a few seconds after sending you to the page. While this doesn’t use much power by itself, it does add up over time with everything else that is running in the background.

4) Disable Auto-Updates: When your OS goes on an update, you are always given the option whether or not to install it right away since updates can sometimes cause issues if they aren’t compatible with something already installed on your computer. However, these updates are important because they fix bugs and/or security flaws within your OS that could potentially lead to lower battery life or even laptop damage in some cases. By downloading them when you are connected to an AC adapter, your system will be less buggy and more secure which boths laptop battery life.

5) Manage Apple Push Notifications: You can manage Apple Push notifications within your System Preferences. There is a setting that automatically sends every notification to the Notification Center and you can adjust this to send notifications directly to Notification Center without sending one to the dock, which will save battery life by reducing CPU usage that comes with running apps in the background for no reason.

6) Disable Features You Don’t Need: There are quite a few things on your MacBook that use more battery than others including (but not limited to) Time Machine (back-up feature), Spotlight (searching for items like apps, contacts, etc.), Bluetooth (see point 3 above), Wi-Fi (use Ethernet whenever possible).

7) Make Sure Your Software is Up to Date: Apple software updates usually make small improvements that might seem insignificant but even those can add up to significant amounts of time between charges as well as better performance when using the battery. The macOS operating system also has small updates from time to time that can improve your MacBook’s battery life and device security.

8) Turn Your MacBook Off When It is Not In Use: If you are going to be away from your MacBook for more than a few hours, turn it off. It’s not as convenient as sleep mode, but it does save battery life and the machine will warm up faster when you return as well as have all of your programs ready to go once you open it back up again. And lastly, if you’re going to store it in a laptop bag, either close the lid or remove the battery. This is because leaving the battery plugged into a bag that sits on a shelf can cause it to discharge slightly even though there is no power being used whatsoever. So take out your battery or close your MacBook’s lid whenever possible with these scenarios.

9) Avoid Heat When Possible: For those who plan to use their laptops for hours on end, it’s a good idea to take breaks every now and again. If you find yourself constantly having to use your laptop with little or no breaks in between, chances are you aren’t allowing the hardware enough time to cool down from time to time. This means that you should take a break from using it after about twenty minutes of constant usage so that you don’t over-stress any components.

10) Try Using an External Battery Pack: If you’re constantly drained by your MacBook during short spurts of work, there’s always the option of purchasing an external battery pack. They range anywhere between $200-$250 dollars but can allow you up to ten hours of unplugged usage. You can get them from eBay.

11) Disable Any Unnecessary Hardware Extensions

12) Turn Off Location Services for Apps You’re Not Using

13) Avoid Over-Charging your MacBook’s Battery

14) Disable Automatic Graphics Switching on Newer MacBooks (2012+)

15) Enable Power Nap in Energy Saver Preferences If you have a brand new MacBook Pro with Retina Display, the first thing that should do is disable automatic graphics switching. The integrated graphics processor will suck a lot more power than a discrete GPU.


16) Recharge your MacBook’s Battery to 100% every once in a while: In order to ensure that the battery is always operating at its max capacity, recharge it when it falls below 95%. You can monitor this from your Mac OS X status bar or through the Menu Bar icon for CoconutBattery.

17) Schedule times during the day where you utilize your MacBook’s Power Adapter

18) Avoid using external keyboards and mice when possible
