In this guide, you’ll learn the main causes of iPhone overheating and the most effective ways to fix it.

Why Is My iPhone Overheating?

Your iPhone may overheat due to:

• Intensive apps (gaming, video editing)

• High screen brightness

• Hot environment or direct sunlight

• Charging issues or faulty cables

• Software bugs or background processes

Identifying the cause is the first step to fixing the issue.

1. Close Background Apps

Apps running in the background can increase CPU usage.

What to do:

• Open the App Switcher

• Swipe up to close unused apps

2. Avoid Using iPhone While Charging

Using your iPhone during charging generates extra heat.

👉 Let your device charge without heavy usage.

3. Reduce Screen Brightness

High brightness levels increase heat.

• Lower brightness manually

• Enable Auto-Brightness

4. Remove Case While Charging

Some cases trap heat.

👉 Remove your case while charging or during heavy use.

5. Update iOS

Software bugs can cause overheating.

Steps:

• Go to Settings → General → Software Update

• Install the latest version

6. Turn Off Background App Refresh

Background activity increases CPU load.

• Go to Settings → General → Background App Refresh

• Turn it off or limit it

7. Disable Location Services (If Not Needed)

Constant GPS usage can heat your device.

• Go to Settings → Privacy & Security → Location Services

• Set apps to “While Using”

8. Avoid Direct Sunlight

Heat from the environment can raise your iPhone’s temperature quickly.

👉 Keep your device in a cool, shaded place.

9. Restart Your iPhone

Restarting clears temporary processes that may cause overheating.

👉 Restart your device regularly.

10. Reset All Settings (If Needed)

If overheating persists:

• Go to Settings → General → Transfer or Reset iPhone

• Tap Reset All Settings

👉 This resets system settings without deleting data.

When Overheating Becomes Serious

You should take action if:

• iPhone shows temperature warning repeatedly
