Curious about the status of your Mac laptop battery? Checking the condition and maximum capacity of a battery in modern macOS versions is actually quite straightforward. If you've owned your MacBook, MacBook Pro, or MacBook Air for some time now, you may have already noticed that the battery performance isn't as good as when you first bought the device.

Most people are aware that the batteries in electronic devices degrade gradually over time. Therefore, don’t expect the same level of battery life on a MacBook you’ve used regularly for years since it’s no longer operating at peak performance. That's why it's important to check how your Mac's battery has held up during your usage. And if you find that the battery performance is poor, you might want to consider getting it replaced or serviced by Apple.

So, are you looking to check the health of your Mac laptop battery? Then you're in the right place!

How to Check Battery Health on MacBook Pro, MacBook Air, MacBook

Battery Health reporting was introduced with the macOS 10.15.5 Catalina update, so ensure your Mac is running a reasonably recent version of macOS to access this feature.

1. Click the ? Apple menu located at the top-left corner of your desktop, then select “System Preferences” from the dropdown menu.
2. This will open the System Preferences panel in a new window. In this panel, click on “Battery” to proceed further.
3. You’ll see your Battery usage history for the past day here. Next, click on “Battery” from the left pane to view its health-related information.
4. Some power-saving options will be displayed on the screen. At the bottom of the window, locate the “Battery Health” option. Click on it.
5. A pop-up window will appear containing all the necessary battery details. Pay attention to the maximum capacity percentage shown here. To understand the basic condition, simply review the Battery Condition section. Once done, click OK to close the window.

This is how you can easily assess how well your Mac's battery is performing.

The battery condition will display as normal as long as the maximum capacity of your Mac's battery remains above 80%. When it drops below this threshold, the condition will change to indicate a service requirement, suggesting it's time to replace the battery through Apple.

To put it simply, a maximum capacity of 80% means your Mac's battery is delivering 80% of the original rated battery life for your specific model. For a MacBook that's around one year old and used frequently, a maximum capacity above 90% is considered acceptable. Most users begin considering a battery replacement after two years when the capacity typically falls below 80%.

Another alternative is checking the Mac battery cycle count, which can also provide insights into battery usage history, performance, and overall health by showing how often the battery has been charged and discharged.

Apple introduced Battery Health reporting shortly after facing backlash for deliberately slowing down older iPhone models based on their battery conditions. While the battery health feature has been available on iPhones since 2018, it took Apple a few more years to bring this functionality to Macs. You can even check the battery health of your Apple Watch too.
