Why Does iPhone 12 Overheat and How to Fix It

Common Causes of iPhone 12 Overheating

The iPhone 12, a technological marvel, can occasionally succumb to the issue of overheating. This phenomenon, if left unchecked, can not only impair the device’s performance but also shorten its lifespan. To address this problem, it’s essential to delve into the underlying causes and explore effective troubleshooting methods.

One of the primary culprits behind iPhone 12 overheating is the utilization of resource-intensive applications and games. These demanding software programs place a significant burden on the device’s processor, resulting in elevated temperatures. Moreover, excessive screen brightness and running multiple apps simultaneously can exacerbate the situation.

Environmental factors, such as prolonged exposure to direct sunlight and inadequate ventilation due to the use of bulky phone cases, can also contribute to overheating. Additionally, background processes running stealthily in the background can add to the thermal load experienced by the iPhone 12.

Symptoms of iPhone 12 Overheating

Recognizing the telltale symptoms of iPhone 12 overheating is crucial for prompt intervention and effective troubleshooting. The most apparent manifestation is an abnormally warm or hot device, a sign that the internal temperature has risen beyond acceptable levels.

Other symptoms include sluggish performance, characterized by slow app loading times and stuttering animations. In severe cases, the iPhone 12 may automatically shut down as a protective measure to prevent permanent damage.

Rapid battery drain is another indicator of overheating, as the device’s energy reserves are depleted in an attempt to regulate temperature. Recognizing these symptoms and taking immediate action can help mitigate the risks associated with overheating.

Troubleshooting Steps

If you encounter iPhone 12 overheating issues, implementing a series of troubleshooting steps can help resolve the problem and restore optimal device functionality.

A. Reduce Device Activity

To alleviate overheating, begin by reducing strenuous device activity, such as closing unused applications. Lowering the screen brightness settings also helps minimize heat generation. Furthermore, avoid prolonged use of high-power apps, especially during charging.

B. Cool Down Device

When the iPhone 12 overheats, allowing it to cool down is paramount. Start by powering off the device and letting it rest until it returns to room temperature. Additionally, place the iPhone in a cool, shaded area with good ventilation. Removing any protective case that may trap heat can further facilitate cooling.

C. Check Battery Health

Battery health can significantly impact device temperature. Navigate to the iPhone’s Settings menu, select Battery, and then Battery Health. Ensure the battery’s maximum capacity is above 80%, as degraded batteries are more prone to overheating.

D. Update Software

Software updates often include bug fixes and performance enhancements that can address overheating issues. Check for available iOS updates in the Settings menu, and install them promptly. Installing the latest software ensures that your iPhone 12 operates with optimal efficiency.

E. Reset Device

If other troubleshooting methods prove unsuccessful, consider resetting your iPhone to factory settings. This drastic measure erases all data from the device, so it’s essential to back up your important files before proceeding. After resetting, set up your iPhone as a new device, without restoring from a backup.

F. Contact Apple Support

Should overheating persist despite implementing the aforementioned troubleshooting steps, it’s advisable to contact Apple Support for further assistance. They may provide additional troubleshooting guidance or arrange for repair options if necessary.

Tips to Prevent Future Overheating

To minimize the likelihood of future iPhone 12 overheating episodes, adopt proactive measures to prevent excessive heat buildup.

Close unused apps promptly, as they can consume resources and contribute to overheating. Avoid using the device in extreme temperatures, such as direct sunlight or freezing cold. Limit background app refresh to reduce unnecessary device activity.

Invest in a protective case with good heat dissipation properties, allowing heat to escape effectively. Additionally, use third-party applications to monitor device temperature and prevent it from reaching critical levels.

iPhone 12 overheating, while a cause for concern, can be effectively addressed by identifying the underlying causes and implementing appropriate troubleshooting measures. From reducing device activity and cooling it down to checking battery health and updating software, a proactive approach can prevent overheating and ensure optimal device performance.

By following the troubleshooting steps outlined in this guide and adopting preventive measures, you can mitigate overheating risks and extend the lifespan of your iPhone 12, empowering you to enjoy seamless and reliable mobile computing experiences.


Understanding the causes, symptoms, and potential solutions to iPhone 12 overheating is crucial to protect your device and avoid any performance issues. By addressing the factors that contribute to overheating, such as high-power apps, excessive screen brightness, and multiple app usage, you can effectively manage device temperature. If overheating persists, consider troubleshooting steps like reducing device activity, cooling it down, or updating software. Remember, regular maintenance and preventive measures, such as closing unused apps, avoiding extreme temperatures, and using a case that allows for heat dissipation, can help prevent future overheating and ensure optimal iPhone performance. By following these recommendations, you can enjoy a smooth and reliable user experience on your iPhone 12.

FAQs about why does iphone 12 overheat

Why does my iPhone 12 get hot when playing games?
