Why Battery Health Matters

• Directly affects MacBook performance and speed.
• Overused batteries can cause overheating and damage internal components.
• Helps determine whether a battery replacement is needed.
• Important when checking a used or refurbished MacBook.

How to Check Battery Health on macOS

1. Through System Settings (macOS Ventura, Sonoma, Sequoia)

• Go to System Settings.
• Select Battery.
• Click on Battery Health.
• You will see:
  • Maximum Capacity (%) – Current battery health.
  • Battery Condition – Normal / Service Recommended.

2. Through macOS System Information

• Hold the Option key and click the Apple Logo.
• Select System Information.
• In the sidebar, choose Power.
• Check:
  • Cycle Count – Number of charge cycles completed.
  • Condition – Battery health status.
  • Full Charge Capacity (mAh) – Should be close to design capacity.

Understanding Cycle Count

Most modern MacBooks have a maximum recommended cycle count of 1000. If the cycle count is close to or above this limit, the battery will drain faster and may require replacement.

• 0–300 cycles: Excellent health.
• 300–700 cycles: Good but aging.
• 700–1000 cycles: Nearing end of life.
• 1000+ cycles: Replacement recommended.

Signs Your MacBook Battery Needs Service

• MacBook shuts down at 20–40% battery.
• Battery drains unusually fast.
• MacBook feels warmer than usual.
• “Service Recommended” appears in battery settings.
• Battery doesn’t charge or gets stuck at a percentage.
• Performance feels slow or laggy.

Checking Battery Health Before Buying a Used MacBook

Always inspect battery condition when purchasing a second-hand or refurbished device, as a weak battery can lead to hidden repair expenses.

• Check cycle count using System Information.
• Ensure battery health is above 80%.
• Avoid devices showing Service Recommended.
• Confirm the battery charges normally.
• Watch for overheating while plugged in.
