Why Is My iPhone 12 So Hot?

Smartphones have become an essential part of our lives, but sometimes they can give us a headache, especially when they start overheating. If you’re an iPhone 12 user, you might have noticed that your phone tends to get uncomfortably warm at times. This can be a concern, as overheating can damage your phone and shorten its lifespan. In this article, we’ll explore the common causes of iPhone 12 overheating and provide some troubleshooting tips to help you keep your phone cool and functioning properly.

Common Causes of iPhone 12 Overheating

Identifying the cause of your iPhone 12 overheating is the first step towards finding a solution. Here are some of the most common culprits:

1. Excessive Background App Usage: Even when you’re not actively using an app, it can still run in the background, consuming resources and generating heat. Too many background apps running simultaneously can put a strain on your phone’s processor and lead to overheating.

2. Prolonged Use of Demanding Apps: Games, video streaming apps, and other resource-intensive applications can push your iPhone’s processor to its limits. Extended use of these apps generates significant heat, especially when combined with other factors like high ambient temperature.

3. Charging While Using the Phone: When you charge your iPhone while simultaneously using it, the charging process adds additional heat to the phone. This is because the battery generates heat as it charges, and using the phone while charging puts even more strain on the battery.

4. High Ambient Temperature: Extreme heat, such as direct sunlight or high temperatures in enclosed spaces, can cause your iPhone to overheat even if you’re not using it heavily. Heat from the environment can transfer to your phone and cause its internal temperature to rise.

5. Hardware Issues: In rare cases, overheating can indicate underlying hardware issues, such as a faulty battery or a damaged processor. Hardware problems can disrupt the phone’s thermal regulation mechanisms, leading to excessive heat buildup.

Troubleshooting Overheating Issues

Now that you know the potential causes of your iPhone 12 overheating, let’s explore some effective troubleshooting tips:

1. Force Restart the iPhone: A simple force restart can often resolve minor software glitches that may be contributing to overheating. To force restart your iPhone 12, quickly press and release the Volume Up button, then quickly press and release the Volume Down button. Finally, hold down the Side button until the Apple logo appears.

2. Close Unused Apps: Closing background apps can free up resources and reduce heat generation. To close apps, swipe up from the bottom of the screen and pause in the middle. Swipe up on the app previews to close them.

3. Update Software and Apps: Software updates often include bug fixes and performance improvements that can help address overheating issues. Make sure your iPhone 12 is running the latest iOS version and that all your apps are up to date.

4. Adjust Screen Brightness: The screen is one of the most power-hungry components of your iPhone. Reducing the screen brightness can help conserve battery and reduce heat generation. You can adjust the brightness manually in the Control Center or enable Auto-Brightness to adjust it automatically based on the ambient light level.

5. Reduce Wi-Fi and Bluetooth Usage:¬†Wi-Fi and Bluetooth connections constantly transmit data, which can generate heat. If you’re not actively using these connections, consider turning them off to conserve battery and reduce heat.

6. Use Power-Saving Mode: Power-Saving mode throttles down your iPhone’s performance and limits background activity, which can help reduce heat generation. You can enable Power-Saving mode by swiping down from the top right corner of the screen and tapping the battery icon.

Advanced Troubleshooting

If the basic troubleshooting tips haven’t resolved your overheating issue, you may need to try more advanced solutions:

1. Check for Hardware Damage: If your iPhone 12 has been dropped or damaged, it may have sustained internal damage that is causing overheating. Inspect your phone for any visible damage, such as cracks or dents.

2. Restore the iPhone to Factory Settings: A factory reset can eliminate any software issues or corrupted data that may be contributing to overheating. However, this will erase all your data, so be sure to back up your iPhone before proceeding.

3. Contact Apple Support: If you’ve tried all the troubleshooting tips and your iPhone 12 is still overheating, it’s time to contact Apple Support. They can provide further assistance and determine if your phone needs repair or replacement.

Prevention Tips

To prevent your iPhone 12 from overheating in the future, follow these tips:

1. Avoid Using the Phone in Direct Sunlight: Extended exposure to direct sunlight can significantly increase your iPhone’s temperature. Try to use your phone in the shade whenever possible.

2. Use a Cooling Case or Cooling Pad: Cooling cases and pads are designed to dissipate heat from your iPhone. These accessories can help keep your phone cool, especially when using it for extended periods or in hot environments.

3. Charge the Phone in a Cool Environment: When charging your iPhone, place it in a cool, well-ventilated area. Avoid charging it in direct sunlight or enclosed spaces where heat can accumulate.

4. Limit Gaming and Video Streaming: Resource-intensive activities like gaming and video streaming can generate significant heat. Limit your use of these activities or take breaks to allow your phone to cool down.

5. Disable Unnecessary Notifications: Notifications can wake up your iPhone’s screen and drain the battery, which can contribute to overheating. Disable unnecessary notifications to reduce background activity and heat generation.


If you’ve been wondering “why is my iPhone 12 so hot,” it’s important to troubleshoot the issue. Excessive background app usage, prolonged heavy app use, and charging while using the phone are common causes of overheating. Try force restarting your iPhone, closing unused apps, and adjusting screen brightness to resolve the problem. If these basic troubleshooting steps don’t help, consider checking for hardware damage or contacting Apple Support. Prevent future overheating by avoiding direct sunlight, using a cooling case, and limiting graphic-intensive activities. By following these tips, you can keep your iPhone 12 running cool and efficiently.
