iPhone overheating is a common problem that can occur for a variety of reasons. While it is usually not one factor for concern, it is important to understand the causes of iPhone overheating and what you can do to fix it.

iPhone Overheating After iOS 17 Upgrade

Part 1. Why Does My iPhone Overheat

iPhone overheating is when your iPhone's temperature rises to a level that is uncomfortable to hold or could potentially damage the device. Apple states that the normal operating temperature for an iPhone is between 32° F (0° C) and 95° F (35° C). When the temperature exceeds 95° F, the iPhone may begin to throttle its performance or even shut down to protect itself from damage.

Normal Operating Temperature for iPhone

When you use your iPhone in a hot environment, it may easily get overheated. Charging your iPhone can also cause it to heat up slightly, but this is usually not a cause for concern. However, if your iPhone is overheating while charging, it could be a sign of a problem with the battery or charger.

Some apps, such as games, video editing apps, and navigation apps, can require a lot of processing power from your iPhone. These demanding apps can cause the iPhone to heat up, especially if you are using the app for a long period of time. If you have many apps running in the background, your iPhone's processor has to work harder to keep them all running. That will lead to the iPhone overheating issue.

Sometimes, software bugs can also cause iPhone overheating. If you have just installed a software update or if you are using a beta version of iOS, it is possible that a software bug is causing the overheating problem.

In rare cases, a hardware issue, like a faulty battery or processor, can also cause your iPhone to overheat. If your iPhone is overheating after upgrading to a new iOS version like iOS 17, the cause may be hardware incompatibility. You should know that new iOS versions may not be fully compatible with all iPhone models.

Part 2. Five Ways to Fix iPhone Overheating After Upgrading iOS

If you are using your iPhone in a hot environment, move to a cooler spot. If your iPhone is overheating while charging, you can unplug it from the charger, wait for several minutes, and check if it is back to a normal temperature. Try removing it from its case and help your iPhone to cool down more quickly. If the overheating problem still exists, use the following methods to troubleshoot it.

Finish Background Tasks and Close Unnecessary Apps

If you have just installed a software update, give your iPhone some time to finish running its background tasks. Once the background tasks are finished, your iPhone should cool down. If your iPhone is overheating, close unused apps. This operation will help to free up resources and reduce the workload on your iPhone's processor. Also, you should avoid using processor-intensive apps. If you need to use one of these apps, try to use it for short periods of time and give your iPhone a break in between.

Restart Your iPhone to Fix the Overheating Issue

A simple restart can often fix minor software glitches that cause your iPhone to overheat. You can take the regular way to power off the iOS device. Then press the power button to turn it on.

Update iOS Version to Prevent iPhone Overheating

The new iOS 17 is still optimizing. When your iPhone is overheating after upgrading to a new version of iOS, it needs to index your files and optimize the software. That can be a demanding process that can cause your iPhone to heat up temporarily. The iPhone overheating bug can be fixed with new software. Go to Software Update from the Settings app to check for updates.

Enable Low Power Mode to Cool Your Overheated iPhone Down

Part 3. FAQs of iPhone Overheating

Is it normal for an iPhone to overheat during setup?

It is normal for your iPhone to overheat slightly during setup. That is because the iPhone is working hard to set up your account, download apps, and index your files. The overheating should subside after the setup process is complete. However, if your device is overheating excessively during setup or if it continues to overheat even after the setup process is complete, there may be a problem.

Does an overheated iPhone damage the battery life?

Yes, an overheated iPhone can damage the battery life. When an iPhone overheats, the battery's internal chemistry is disrupted, which can lead to a decrease in capacity and lifespan.

Can I put my phone in the fridge to cool it down?

No, you should not put your phone in the fridge to cool it down. The sudden temperature change may cause condensation to form inside your device, which can damage the electronic components. Moreover, the cold temperature can slow down your phone's performance and even cause it to shut down.
