The battery is one of the most critical components of a MacBook, determining how long the device can run on a single charge before needing to be plugged in. Over time, battery life and performance degrade, making it essential for users to check the battery’s health periodically. For MacBooks powered by Apple’s M-series chips, macOS provides built-in tools to monitor battery condition and cycle count.
How to Check MacBook Battery Health
Apple provides an easy way to view a MacBook’s battery health status through system settings. Follow these steps to check the health of the MacBook’s battery:
- Click on the Apple Menu in the upper-left corner of the screen.
- Select System Settings.
- Scroll down and choose Battery.
- Look for the section labeled Battery Health.
Here, macOS will display the battery’s condition, which may show as one of the following statuses:
- Normal: The battery is functioning properly.
- Service Recommended: The battery has significantly degraded, and replacing it might be necessary.

How to Check Battery Cycle Count
A battery cycle count indicates how many full charge cycles a MacBook battery has gone through. Apple-designed lithium-ion batteries are typically rated for around 1,000 charge cycles before performance begins to degrade noticeably.
To check the battery cycle count on an M-series MacBook:
- Click the Apple Menu and select About This Mac.
- Click on More Info to open the system overview.
- Scroll down and click System Report.
- In the left sidebar, select Power.
- Look for the section labeled Cycle Count under Battery Information.

If the cycle count is approaching 1,000 or higher, users may experience reduced battery life, indicating it may be time to replace the battery.
Tips to Extend MacBook Battery Life
Battery health can be maintained over time with proper care. Here are some useful tips to extend a MacBook’s battery life:
- Enable Optimized Battery Charging in the Battery settings.
- Avoid frequent full discharges; keep battery levels between 20% and 80% when possible.
- Keep macOS updated to take advantage of battery management improvements.
- Avoid exposing the MacBook to extreme temperatures for prolonged periods.
- Use original Apple chargers or high-quality third-party alternatives.
Frequently Asked Questions
What is a normal battery cycle count for a MacBook?
Apple estimates that most MacBook batteries will last for around 1,000 charge cycles before significant degradation occurs. However, proper usage and care can help extend battery performance beyond this limit.
Does replacing the battery reset the cycle count?
Yes, when a MacBook battery is replaced, a new cycle count starts from zero.
How often should battery health be checked?
It is good practice to check battery health every few months, especially for older MacBooks, to ensure optimal performance.
What happens if a MacBook battery reaches 1,000 cycles?
Reaching 1,000 cycles does not mean the battery will stop working immediately, but users may notice a reduced battery life and inconsistent performance. It is recommended to replace the battery at this stage.
Can a MacBook be used while charging?
Yes, using a MacBook while charging does not harm the battery. macOS intelligently manages power when the device is plugged in to prevent overcharging.
Is it bad to keep the MacBook plugged in all the time?
While modern MacBooks have battery management features, it is a good idea to occasionally unplug and use the battery between 20% and 80% to maintain long-term health.
