Questions about Battery Health
How do I check the cycle count on my MacBook?
Open Battery Health in Toolbox, or go to System Information and look under Power. Most recent MacBooks are rated for 1,000 cycles.
What is a good battery health percentage for a MacBook?
Apple designs batteries to keep about 80 percent of their original capacity at their rated cycle count. Below 80 percent, macOS may show Service Recommended.
Why is my MacBook charging slowly?
A low-wattage charger, a weak USB-C cable or a hub can limit charging. Battery Health shows the charger's wattage so you can tell whether it's enough for your Mac.
