How to Check Battery Health on Your Mac and iPhone

Indicators, apps, and tips to decide if it’s time for a battery replacement or just a change in habits

Your battery might be the most crucial — and most ignored — part of your Apple device. Whether it’s an iPhone or a MacBook, checking its health can help you make smarter choices about repairs, upgrades, or daily use. Here’s how to do it easily.

🍏 1. Checking battery health on iPhone

Apple provides a built-in way to monitor battery condition:

• Go to Settings > Battery > Battery Health & Charging

• Look for the “Maximum Capacity” percentage

New iPhones show 100%. If it drops below 80%, Apple recommends replacing it.

📌 Also check for the warning:“Your battery’s health is significantly degraded.”

💻 2. Checking battery health on MacBook

macOS has a native way to assess battery condition:

• Hold the Option key and click the battery icon

• You’ll see one of the following:

  • Normal

  • Service Recommended

🔧 For more detailed data:

• Go to Apple Menu > About This Mac > System Report > Power

• Look for “Cycle Count” and “Condition”

💡 Most modern MacBooks are rated for 1,000 charge cycles. Beyond that, performance may degrade gradually.

🛠 3. Helpful battery monitoring apps

You can dig deeper using third-party apps:

• iPhone:

  • Battery Life, CoconutBattery (with Mac connection), 3uTools

• Mac:

  • CoconutBattery

  • iStat Menus

  • Battery Monitor

These apps show real-time charge, temperature, battery age, and cycle count.

🧠 4. What to do if your battery is worn out

If your battery’s health is declining:

• Consider professional battery replacement

• Lower screen brightness and limit background apps

• Use energy-saving modes

• Avoid extreme heat or cold
