Why is My iPhone 12 Overheating?

iPhone 12 users have reported encountering overheating issues, which can stem from various factors. This article aims to shed light on the underlying causes of this problem and provide effective troubleshooting solutions.

Demanding Apps and Games

Engaging in processor-intensive activities like running demanding apps or playing graphics-heavy games for extended periods puts a significant strain on your iPhone’s CPU and GPU. This increased workload can lead to overheating as the components struggle to keep up with the demand.

To mitigate this issue, consider limiting your usage of such apps, especially during extended sessions. Additionally, take breaks between gaming or app usage to allow your phone to cool down.

Excessive Background Activity

Your iPhone 12 may continue running certain apps and services in the background even when you’re not actively using them. These operations can consume valuable resources and contribute to overheating. To address this, it’s advisable to regularly force-close any apps you’re not currently using.

To force-close apps, swipe up from the bottom of your screen, pause midway, and then slide individual app cards upwards. This will terminate their background activity.

Direct Sunlight or Heat Exposure

Exposing your iPhone 12 to direct sunlight or leaving it in hot environments can result in a rapid increase in temperature. The device’s internal components are not designed to withstand extreme heat, and such conditions can lead to overheating.

To prevent this, avoid leaving your iPhone in direct sunlight for prolonged periods. If you’re in a hot environment, seek shade or use a cooling case designed to dissipate heat.

Charging While Using

Using demanding apps or engaging in other intensive activities while charging your iPhone can put additional stress on the battery and lead to overheating. This is because the charging process itself generates heat, and combining it with other resource-intensive tasks can exacerbate the issue.

To avoid this, it’s best to limit your iPhone’s usage while it’s charging. Allow the device to charge fully before using it for demanding tasks.

Defective Battery or Charger

In some cases, overheating can be attributed to a defective battery or a malfunctioning charger. A damaged battery may struggle to maintain a stable voltage, leading to excessive heat generation. Similarly, a faulty charger may provide an uneven power supply, causing the phone to overheat.

If you suspect a battery or charger issue, try using a different charger or consult a certified technician for further diagnosis.

Troubleshooting and Solutions

In addition to understanding the potential causes of overheating, implementing effective troubleshooting measures is crucial. Here are some practical steps you can take:

Force Close Background Apps

As previously mentioned, force-closing unused apps can help reduce background activity and mitigate overheating. To do this, swipe up from the bottom of the screen, pause midway, and then swipe up on individual app cards to terminate them.

Enable Low Power Mode

Activating Low Power Mode is an effective way to reduce your iPhone’s power consumption. This mode limits background activity, dims the screen, and optimizes performance to extend battery life. To enable it, go to Settings > Battery and toggle on Low Power Mode.

Avoid Direct Heat Exposure

Keep your iPhone out of direct sunlight and away from heat sources, such as radiators or heaters. If you’re outdoors on a hot day, seek shade or use a cooling case to dissipate heat.

Check for App Updates

Regularly updating your iPhone’s apps can address potential overheating issues caused by software bugs or compatibility problems. To check for updates, open the App Store, tap on your profile icon, and then scroll down to see available updates.

Restart Your iPhone

A simple restart can often resolve temporary glitches that may be contributing to overheating. To restart your iPhone, press and hold the Volume Up button and the Side button simultaneously until the Apple logo appears.

Inspect Battery and Charger

If your phone overheats while charging, try using a different charger. If the problem persists, consult a certified technician to check the battery’s health and identify any potential issues.

Consider a Cooling Case

Some third-party cases are designed specifically to provide additional cooling for your iPhone. These cases often feature heat-dissipating materials or built-in fans to help regulate temperature.

Factory Reset

As a last resort, you may need to perform a factory reset to remove any potential malware or corrupted software that could be contributing to overheating. Remember to back up your important data before proceeding with a factory reset.

By following these troubleshooting steps and understanding the potential causes, you can effectively address the overheating issue on your iPhone 12 and ensure its optimal performance.


Understanding the causes of iPhone 12 overheating empowers you to identify and resolve this issue effectively. By addressing excessive background activity, avoiding direct heat exposure, and ensuring a healthy battery and charger, you can maintain your device’s optimal performance. Remember, if troubleshooting measures fail, consider a cooling case or consult a technician for further assistance. By taking these steps, you can prevent overheating and enjoy a seamless user experience with your iPhone 12.

FAQs about why is my iPhone 12 overheating

Why is the back of my iPhone 12 overheating?

The most common cause is gaming. When you play certain high-performance games or graphic-intensive games, your iPhone’s processor has to work much harder, which generates more heat.

Why is my iPhone 12 overheating while charging?

Although wireless charging is convenient, it also causes your iPhone to generate more heat than wired charging. This is because wireless chargers use induction coils to transfer energy to your iPhone, and this process often creates heat.

Why does my iPhone 12 overheat in the sun?

When your iPhone is exposed to direct sunlight for long periods of time, it can cause the device to overheat. This is because the sun’s UV rays can damage the battery and other internal components, which can lead to overheating.

Why is my iPhone 12 overheating while on a call?

When your iPhone is in use for a long period of time, the battery can become depleted and the device can start to overheat. This is especially true if you are using your iPhone for activities that require a lot of power, such as gaming or video streaming.

Why is my iPhone 12 overheating even when it’s not in use?

If your iPhone is overheating even when it’s not in use, it could be due to a number of factors, such as a faulty battery, a software issue, or a hardware problem.
