2. Simply restart your Mac by going to the Apple menu and Restart.

3. Check your battery health. The general condition of your battery may be poor. We previously wrote an article about that topic. You can check that article.

6. You can also use Activity Monitor to figure out energy-consuming apps and processes. Open the Activity Monitor app (Applications / Utilities) and then click the Energy tab.

How to extend your battery life

1. Lower your display’s brightness. The biggest use of battery resources is your Mac’s screen. Adjust its brightness. Click the Apple menu > System Preferences > Display and click the Display tab and adjust the brightness slider. You can also check the box “Automatically adjust brightness”.

2. Disable Wi-Fi and Bluetooth if/when you do not use them. You can disable them by clicking their icons in the status bar.

3. Optimize your Energy Saver settings by going to the Apple menu > System Preferences > Energy Saver. Click the Battery tab. Optimizing these settings will help you extend your battery’s life.

  1. having the high sierra macbook pro 2017.. my battery suddenly shuts off and drains fast today. says 57 percent capacity. never had this quick for year since yesterday. i reckon apple has did something with the OS again grrr

  2. WLAN is the culprit. Seems Catalina does not support to switch off WLAN for older MacBooks in Catalina.

    Make the test: WLAN off > you lose 2% per night, turn it on > you lose 20%

  3. I did everything. I switched off bluetooth, I switched off all the windows, I even stopped using Chrome and started using Safari. When I looked at the battery, it said Safari is consuming a lot of energy. Before Catalina, I used High Sierra and my battery was fine. Now in less than a minute after charging my laptop I see the battery life go down minus 3% – LESS THAN A MINUTE!!! I am seriously considering changing to Windows as I really liked MacBooks for their battery life. Now I have to switch off almost everything including wifi and brightness of the screen – how about just stop using MacBooks at all?

  4. Checked and tested all of the above. Still the battery of my Macbook pro (late 2013) with built in Retina display drains the battery right after installing Catalina IOS. Sometimes my screen just changes into stripes ?!?!
    I am really very unhappy with this. Als the machine warms up when in use.
    Anyone any suggestions?
