How to Check iPhone Battery Health: A Step-by-Step Guide

June 12, 2025 By Steven

Checking your iPhone’s battery health is a simple process that lets you understand how well your battery is performing. By navigating through your device’s settings, you can find out the maximum capacity of your battery, which helps you to determine whether it’s time for a battery replacement. This brief check can help you keep your iPhone running smoothly by alerting you to potential issues with aging batteries. Follow these steps to see how your battery is holding up.

How to Check iPhone Battery Health

If you want to know how your iPhone’s battery is doing, you’re in luck. Apple makes it easy to see your battery’s health right in the settings. Let’s walk through the steps to check this vital information.

Step 1: Open Settings

Go to your iPhone’s home screen and tap the "Settings" app.

The Settings app is where all the magic happens on your iPhone. It’s the control center for everything from Wi-Fi to wallpapers, and right now, it’s going to lead you to your battery health information.

Step 2: Tap on Battery

Scroll down and select "Battery" from the list of options.

In the Battery section, you’ll find a collection of tools that tell you how your iPhone’s battery is doing. This page gives you insights into which apps are using the most battery and lets you toggle on Low Power Mode, among other things.

Step 3: Select Battery Health

In the Battery menu, tap on "Battery Health."

"Battery Health" is a feature that provides a snapshot of your battery’s condition. It shows you the maximum capacity and peak performance capabilities, which are crucial for understanding how much life your battery has left.

Step 4: Review Maximum Capacity

Check the percentage under "Maximum Capacity."

Maximum Capacity is like the health gauge for your iPhone’s battery. A number close to 100% means your battery is in great shape, while a lower percentage indicates wear and tear that might require attention.

Step 5: Look at Peak Performance Capability

Read any messages under "Peak Performance Capability."

This section will tell you if your battery is still supporting peak performance. If your battery is significantly degraded, you might see a message suggesting that your iPhone’s performance is being managed to prevent unexpected shutdowns.

After you complete these steps, you will have a clear understanding of your battery’s health. If your battery’s maximum capacity is low or your iPhone’s performance is being throttled, you may want to consider battery replacement to restore your device to full strength.

Tips for Checking iPhone Battery Health

  • Keep your iPhone updated with the latest iOS version to ensure accurate battery health readings.
  • Consider using Low Power Mode to extend battery life between charges.
  • Avoid exposing your iPhone battery to extreme temperatures, as this can degrade its health.
  • Charge your iPhone before the battery drops below 20% to prolong its lifespan.
  • Use certified chargers and cables to prevent potential battery damage.
