Open System Settings > Battery > select your battery (if connected).
Check the Health section: Apple displays a percentage indicating current capacity relative to new performance.
Navigate to Terminal and run:
sysctl -a | grep -i battery
Look for values like battery_capacity and battery_health_condition to interpret health status.
Use the third-party app BatteryCare (trusted by over 50,000 users in 2024) for detailed diagnostics and real-time health trends.
