January 7, 2026 By Matthew Burleigh

How to Check Battery Health on iPhone

Checking your iPhone’s battery health is a breeze! First, go to "Settings" and select "Battery." Then, tap on "Battery Health." Here, you’ll find everything you need to know about your battery’s performance and capacity. Keep an eye on the "Maximum Capacity" to see how well your battery is holding up. If it’s low, you might want to consider a replacement.

Step-by-Step Guide to Check Battery Health on iPhone

Want to make sure your iPhone battery is in tip-top shape? Follow these simple steps to check its health and ensure it’s running efficiently.

Step 1: Open Settings

Go to the home screen and tap on the "Settings" icon, which is usually a gray gear.

In the settings menu, you can find all options to customize your iPhone. It’s the starting point for accessing battery health.

Step 2: Select Battery

Scroll down the settings menu and tap on "Battery."

In this section, you can see basic battery usage information. It provides insights into your battery consumption over the last 24 hours or 10 days.

Step 3: Tap Battery Health

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

Here, you’ll access detailed information about your battery’s maximum capacity and performance capability. It’s the key to understanding your battery condition.

Step 4: Review Maximum Capacity

Look for the "Maximum Capacity" percentage to understand your battery’s health.

This percentage shows how much your battery’s capacity has decreased since it was new. A lower percentage indicates a need for potential replacement.

Step 5: Check Peak Performance Capability

Read the section on "Peak Performance Capability" to see if your battery supports normal peak performance.

If your battery isn’t performing at its best, your phone might slow down to prevent unexpected shutdowns.

After completing these steps, you’ll have a clear picture of your iPhone battery health. You’ll know if your battery is performing optimally or if it’s time to consider a replacement. Keeping tabs on this can help you avoid unexpected power issues.
