I know we’ve written an article on why you should
DIY your MacBook battery replacement but what if we can prolong our battery lifespan?

As they say, prevention is better than cure! By improving battery life and maximizing your MacBook’s performance, you won’t be wasting the battery cycle count and hence, the need for a MacBook battery replacement. Just follow these 8 simple steps and you won't have to worry about the battery draining quickly again.  

1) Show your Battery percentage 

Okay, this does not actually extend your battery life, BUT it does help in getting a better idea of your MacBook’s performance. And with the battery percentage showing, it does help when trying to diagnose issues with your MacBook when the battery is not performing optimally. 

How to: 

  • Click the Battery icon on the menu bar.
  • Select “Show percentage” 

2) Turn off your Bluetooth and Wi-fi 

Unless you love showing off your music taste to strangers (we don’t recommend doing so but you do you!), there’s a high chance you won’t be using your Bluetooth speakers on the go. Or the Wi-Fi for that matter, to play your emo playlist from Spotify. When not in use, turn off the Bluetooth and Wi-Fi function to save some battery juice. 

How to: 

  • Bluetooth: Click the Bluetooth icon on the menu bar.
  • Select “Turn Bluetooth off”
  • Wifi: Click the Wi-Fi icon on the menu bar.
  • Select “Turn Wi-Fi off”

3) Dim your screen brightness 

The display screen brightness is one of the biggest drainers of your MacBook battery life. If you’re in a very well-lit area, simply lower your screen brightness so that you will have a longer battery life. You don't need the Sun staring at you while you do your work.

How to:

  • Go to the Apple menu and select System preferences.
  • Select “Display” and then drag the brightness slider to adjust the brightness. 

4) Update your software 

Staying current with the latest software update will help optimize your battery’s performance. The software update may include energy-saving features, so make sure your MacBook is using the latest version of MacOS. Also, it's less annoying.

How to: 

  • Go to the Apple menu and select System preferences.
  • Select “Software updates” for updates.
  • If any updates are available, click the "Update Now" button to install them

5) Check which applications are draining your battery

Yes, I’m looking at you now Google Chrome. And Spotify. And Adobe. When not in use, close these applications to save your battery usage. Better still, use applications that are more energy-saving such as Safari for your browser instead of Chrome. 

How to: 

  • Go to the Applications folder and then select “Utilities”
  • Select “Activity monitor”.
  • Under the “Energy tab”, you will see a list of all the applications and processes that use the most power.
  • Start closing those that you are not running currently. 

6) Use the Energy Saver function

Optimize your battery settings to ensure that you don’t waste unnecessary energy. Below are a few ways on how you can optimize your batter’s power. 

How to: 

  • Go to the Apple menu and select System preferences.
  • Select “Energy saver”.
  • Select the “Automatic graphic switching”.
  • Select the “Put Hard Disks to Sleep when Possible”
  • Also, under System Preferences, select “Display” and uncheck the “Automatically adjust brightness”. 

7) Switch-off keyboard backlights

Unless you’re working at night in a dark area, turn off the keyboard backlights when not required as it drains up your battery. (Yes, it does look aesthetically pleasing but turn it off after a minute). 

How to: 

  • Go to the Apple menu and select System preferences.
  • Select “Keyboard”. 
  • On the keyboard tab, check the box for “Turn keyboard backlight off after _ of inactivity” 

8) Remove any unused dongles connected to the MacBook

Disconnect any SD cards, USB devices or hard drives that are not in use as this will drain your MacBook’s battery life. Also, when charging other devices such as your iPhone or iPad, it’s recommended to plug in your MacBook to a power source to prevent it from draining much faster.

Start practicing these good habits

Understandably, these tips may need some adjusting to as you have certain habits and practices that you are used to when using your laptop. However, once you start following these 8 simple tips, you can now ensure that you can increase your MacBook battery life without worry.
