Check Battery Usage on Your MacBook 
• Apple already added a Battery Health feature to its MacOS 10.15.5 that was 
released in April this year, and its successor, macOS Big Sur, has bought more 
tools that reveal the apps which are consuming your MacBook. 
• For the first time, Mac is allowing you to inspect usage in the past 24 hours or 
10 days. Here is how to check.
• Step 1: Open System Preferences. You can either click on the Apple logo on 
the menu bar or in the Applications menu. 
• Step 2: Select the Battery option. 
• A page will appear with a separate battery section. Here you can see your 
battery usage in graphs and charts. This will let you know about any app that is 
running in the background and draining the battery. 
• You can get a rough idea of the health of your MacBook’s battery without the 
Battery Health Checker tool.
• Go to System Preferences  > Power Saver  > Battery Health.
