Identifying the cause is essential for addressing overheating issues. This guide offers solutions to prevent and resolve overheating on your iPhone 15.

How to Fix iPhone 15 Overheating Issue?

Step-by-Step Guide to Fix iPhone 15 Overheating Problems:

Method 1: Restart iPhone 15

If your iPhone 15 Pro or iPhone 15 Pro Max is experiencing random overheating issues or consistent overheating, a simple solution to address minor software glitches is to restart your device. Restarting can also help resolve battery-related problems and enhance overall performance.

To restart your iPhone 15:

  1. Press and hold the Volume Up or Volume Down button and the Side button simultaneously.
  2. Slide the on-screen slider from left to right to turn off your iPhone.
  3. After about a minute, press and hold the Side button until you see the Apple logo, indicating that your iPhone is restarting.

Regularly restarting your iPhone (perhaps once a week) can significantly improve battery life and performance.

Method 2: Avoid Using iPhone 15 in Extreme Conditions

For optimal performance, it’s essential to use your iPhone 15 Pro Max within a temperature range of 32 to 95 degrees Fahrenheit. Exposure to extreme temperatures, whether too hot or too cold, can lead to overheating issues. Avoid direct sunlight exposure or leave your iPhone in a hot car for extended periods. Additionally, resource-intensive tasks like GPS tracking, AR applications, or graphics-intensive games can contribute to overheating, so take breaks to allow your iPhone 15 to cool down when using such features.

Method 3: Choose a Suitable Case

When selecting a case for your iPhone 15, prioritize those designed for heat dissipation. Inadequately designed or bulky cases can trap heat generated during activities like gaming or video streaming, leading to overheating. Ensure your case allows for proper heat ventilation to prevent overheating issues.

Method 4: Keep iOS Up to Date to Fix the iPhone 15 Overheating Issue

Regularly updating your iPhone 15 to the latest iOS version is crucial. Apple releases updates that include bug fixes, security enhancements, and performance improvements. If you experience random overheating or notice increased heat during common tasks like web browsing, ensure that your iPhone 15 is running the most recent stable version of iOS.

To check for updates:

  1. Go to Settings > General > Software Update.
  2. Download and install any available updates.

Method 5: Prioritize Wi-Fi Over Mobile Data

Whenever possible, use Wi-Fi instead of mobile data on your iPhone 15 to mitigate overheating issues. Resource-intensive activities like video calls consume various system resources, including mobile data or Wi-Fi, camera, and audio-video processing, which can generate heat. Wi-Fi generally consumes less power and generates less heat compared to mobile data.

Additionally, remember to turn off Wi-Fi when not in use to conserve battery life and prevent overheating.

Method 6: Activate Low Power Mode

If your iPhone 15 experiences excessive battery drain and overheating, consider enabling Low Power Mode. This mode limits certain functions, such as background app refresh and visual effects, to reduce power consumption and extend battery life. It can be particularly effective in preventing overheating issues.

To activate Low Power Mode:

  1. Swipe down from the Control Center and tap the Battery icon. The battery icon will turn yellow.
  2. Alternatively, Go to Settings > Battery and toggle on Low Power Mode.

When your battery reaches 20%, you’ll receive a prompt to enable Low Power Mode, and it will automatically turn off when your battery reaches 80%.

Method 7: Adjust Screen Brightness and Disable Background Refresh

Maintain an appropriate screen brightness level on your iPhone 15 to prevent overheating. Extremely bright displays can contribute to battery drain and overheating. Aim to keep your screen brightness between 40% and 60% in typical lighting conditions.

Additionally, consider adjusting the Background App Refresh settings. While this feature enhances app performance, it can also consume battery power and generate heat. You can either disable Background App Refresh entirely or selectively enable it for specific apps.

To manage Background App Refresh:

  1. Go to Settings > General > Background App Refresh.
  2. Choose to turn it off entirely or selectively enable it for essential apps.

Method 8: Manage Location Services

Leaving Location Services on at all times can drain your iPhone 15’s battery and lead to overheating. To address this, avoid keeping Location Services enabled continuously.

To manage Location Services:

  1. Navigate to Settings > Privacy > Location Services.
  2. Choose to disable Location Services entirely or grant access to specific apps only when necessary.

Method 9: Close Unused Apps to Fix iPhone 15 Overheating Issue

Failing to close apps you’re not actively using can contribute to overheating on your iPhone 15. Unused apps running in the background consume resources and drain the battery. To prevent overheating, periodically force-close apps that are not in use.

To close unused apps:

  1. Swipe up from the bottom of the screen to access the App Switcher.
  2. Swipe left or right to find the app you want to close.
  3. Swipe it up or off the screen to close it.

Method 10: Identify Power-Draining Apps

If you notice that a specific app is causing overheating on your iPhone 15, it’s essential to identify and address it. Some apps may consume excessive power, putting a strain on the CPU and causing overheating.

To identify power-draining apps:

  1. Go to Settings > Battery.
  2. Review the battery usage data to identify apps that are using the most power.
  3. Consider uninstalling or updating power-hungry apps to resolve overheating issues.

Method 11: Contact Apple Support

If you’ve followed the previous methods and your iPhone 15 continues to overheat, it’s advisable to seek assistance from Apple Support or visit an Apple Store. There may be underlying issues with your iPhone’s internal components that require professional evaluation and repair.
