Overheating can be a common issue for many smartphone users, including those with the iPhone 15. I’ve noticed that my iPhone 15 gets so hot, especially when using certain apps or charging. It can be frustrating and even concerning when your phone becomes uncomfortably warm, and it can also lead to performance issues or even damage. In this article, we will explore some of the reasons why your iPhone 15 might be overheating and provide strategies to help you address this issue.

There are several factors that can contribute to overheating in the iPhone 15. Intense gaming, heavy use of graphics-intensive apps, or prolonged video streaming can push the phone’s processor and graphics card to work harder, generating more heat. Additionally, charging the phone while using it or exposing it to direct sunlight can also lead to overheating. In some cases, a faulty battery or other hardware issues may also be the culprit.

I’ve worked as a tech writer for several years, and I’ve encountered many users who have experienced overheating issues with their iPhones. I understand how frustrating it can be, so I’ve compiled some strategies to help you prevent and address overheating in your iPhone 15. I’ve found that reducing screen brightness, closing unused apps, and avoiding charging while using the phone can significantly reduce the chances of overheating. I’ve also tried using a cooling case or charging pad to dissipate heat more effectively.

Why Does My iPhone 15 Get So Hot?

If your iPhone 15 is experiencing overheating issues, you’re not alone. This can be a frustrating and concerning problem, but rest assured, there are steps you can take to troubleshoot and resolve the issue. While overheating can be caused by a variety of factors, both hardware and software-related, in this article, we’ll explore the most common causes and provide a comprehensive guide to help you diagnose and fix the problem.

Common Causes of Overheating

Overheating issues can stem from various sources, including:

Hardware Issues:

  • Faulty Battery: A malfunctioning or degraded battery can struggle to manage power effectively, leading to excessive heat generation.
  • Overloaded Processor: The iPhone’s powerful processor, when burdened with demanding tasks or multiple apps running simultaneously, can cause the device to overheat.
  • Cooling System Malfunction: The iPhone’s cooling system, comprised of heat sinks and thermal paste, can fail due to wear and tear, resulting in insufficient heat dissipation.

Software Issues:

  • Running Multiple Demanding Apps: Simultaneously running multiple apps that consume significant resources, such as video games or navigation software, can strain the device’s processor, leading to overheating.
  • Corrupted Software Updates: Occasionally, buggy software updates can introduce issues that affect power management, resulting in excessive heat generation.
  • Background Processes or Services Draining Battery: Certain background processes or services, such as location services or push notifications, can drain the battery, leading to overheating.

Troubleshooting Steps

To troubleshoot and resolve overheating issues on your iPhone 15, consider the following steps:

Check Battery Health:

Navigate to “Settings” > “Battery” > “Battery Health” to assess the battery’s condition. Look for any warnings or reduced battery capacity, indicating the need for a battery replacement.

Manage App Usage:

Close any unused apps from the app switcher. Adjust app settings to minimize background activity and consider using energy-saving modes to reduce overall power consumption.

Software Updates:

Ensure your iPhone is running the latest iOS version. Check for and install any available software updates, as they often include optimizations and bug fixes that can address overheating issues.

Reduce Wireless Connectivity:

When not in use, turn off Wi-Fi or Bluetooth to minimize power consumption. Use Airplane Mode in areas with poor signal to conserve battery and reduce heat generation.

Adjust Screen Brightness:

Lower the screen’s brightness level, especially during extended use. Utilize the Auto-Brightness feature to automatically adjust the brightness based on ambient light conditions.

Remove Case or Cover:

Excessive heat can accumulate inside phone cases. Remove the case or cover temporarily to allow for better heat dissipation.

Restart or Force Restart:

Restarting the iPhone can clear memory and close any background processes that may be contributing to overheating. If the device becomes unresponsive, perform a force restart by pressing and holding both the volume up button and the power button simultaneously.

Advanced Troubleshooting

If the aforementioned troubleshooting steps fail to resolve the overheating issue, consider these advanced options:

Reset iPhone Settings:

Go to “Settings” > “General” > “Reset” and choose “Reset All Settings.” This will reset all iPhone settings to their default values, potentially resolving software-related issues causing overheating.

Contact Apple Support:

If the issue persists, reach out to Apple Support for further assistance. They may recommend additional diagnostics or repair options, such as a battery replacement or hardware diagnostics.

By following these troubleshooting steps, you can effectively diagnose and resolve overheating issues on your iPhone 15, ensuring optimal performance and longevity.


If your iPhone 15 is overheating, addressing the underlying causes is crucial to maintain its optimal performance and prevent long-term damage. By following these troubleshooting steps, you can effectively identify and resolve the issue. If the problem persists, don’t hesitate to contact Apple Support for further assistance. Remember, a well-maintained iPhone will serve you reliably for years to come.
