June 23, 2025 By Matthew Burleigh

Checking the battery health on your iPhone is a breeze and crucial for keeping your device running smoothly. From ensuring your phone doesn’t die during a crucial call to understanding when it’s time to consider a replacement, knowing how to assess your battery’s health is a game-changer. In just a few simple steps, you can access this vital information directly from your settings. Let’s dive into the process and take control of your iPhone’s battery performance.

How to Check Battery Health on iPhone

In this section, we’ll walk you through the steps needed to check the battery health of your iPhone. By following these steps, you’ll learn how to view your battery’s maximum capacity and whether it’s functioning at peak performance.

Step 1: Unlock Your iPhone

Grab your iPhone and unlock it using your preferred method.

It doesn’t matter if you use Touch ID, Face ID, or a passcode to unlock your phone. Once unlocked, you’ll find yourself on the home screen, ready to dive into the settings.

Step 2: Open Settings

Locate and tap on the "Settings" app, which is typically represented by a gear icon.

The Settings app is your gateway to a multitude of features and options. It’s where you can customize almost everything about your iPhone, including checking your battery health.

Step 3: Scroll to Battery

Navigate through the Settings menu and find the "Battery" option.

The Battery section offers insights into your battery usage habits and provides access to the Battery Health feature, which we’re interested in right now.

Step 4: Tap on Battery Health

Select "Battery Health" from the list of options within the Battery menu.

This section reveals detailed information about your battery’s condition. From here, you can see both the Maximum Capacity and Peak Performance Capability of your battery.

Step 5: Review Battery Information

Read the Maximum Capacity and Peak Performance Capability details provided.

Maximum Capacity tells you how much charge your battery can hold compared to when it was new. Peak Performance Capability indicates whether your battery can deliver peak power, which is vital for smooth performance.

Once you’ve completed these steps, you’ll have a good understanding of your iPhone’s battery health. If your battery is no longer supporting peak performance, you might notice your phone slowing down or shutting off unexpectedly. You will also receive recommendations from Apple if a battery replacement is needed.

  • Keep your iOS updated to ensure optimal battery management features are enabled.
