Thus, if you also want to fix iPhone overheating issues with your device, make sure to go through the following solutions one by one:

Don’t use Heavy Cases with your iPhone

Unlike other software issues which may cause heating in your iPhone, the case of your iPhone can also cause the same. This is due to the reason that your iPhone uses its metal body and glass back to dissipate heat. Due to this, if the body of your iPhone is covered and insulated, it won’t be cooled off properly. Thus, it is quite important to ensure that you are not using any heavy cases with your iPhone which can restrict its cooling and cause it to heat up.

Look for Crashing Apps in your iPhone

If there are any apps installed on your iPhone which have not been working properly and crashing quite a lot, they can also cause heating issues on your iPhone. Any such apps which are crashing on your iPhone will cause a lot of CPU usage in the background. And as you would expect, this high CPU usage will also result in your iPhone overheating. Hence, make sure to check for crashing apps installed on your Phone as given here:

  • First, open the Settings app on your iPhone and open the Privacy menu.
  • Here, go to the Analytics option and open Analytics Data.

Update all your iPhone Apps

Apart from crashing, the apps installed on your iPhone can also cause high CPU usage and overheating issues if they are not updated to the latest version. Old versions of your favorite apps might not work the best with recent versions of iOS which can cause high CPU usage issues. Thus, simply go to the App Store and update all of the apps currently installed on your iPhone.

Look for Battery and CPU Drain Apps in your iPhone

If any app installed on your iPhone is draining the battery and using the CPU quite a lot, it will most likely generate a lot of heat. Therefore, you need to check for such apps to ensure that your iPhone is not overheating because of the same. To do the same, you need to follow the given instructions one by one:

  • Start by opening the Settings app on your iPhone where you have to go to the battery menu.
  • Here, you will see a list of all the apps installed on your iPhone and their respective battery usage.

Update your iPhone to the Latest iOS Version

Even though newer updates of iOS are generally known to cause overheating issues, they can also help fix the same. In some cases, your iPhone might be overheating due to some bug or issue within the operating system. And newer updates of iOS generally come with bug fixes that can get rid of these issues which in return will fix iPhone overheating issues. So, make sure that your iPhone has been updated to the latest version for the same.

Check the Network Connection in your iPhone

If you are using your iPhone for streaming online music or videos, then it is quite important to check your network connection. This is due to the reason that if the WiFi network or the cellular network of your iPhone does not have proper signal strength, it will keep trying to improve the same network or even find networks. As a result, this will result in high CPU usage, more battery drain, and overheating issues with your iPhone.

Change your iPhone’s Screen Brightness

Apart from the CPU of your iPhone, its screen also outputs some amount of heat. While this heat is not that much in most situations, it does become an issue if you are using your iPhone at high brightness levels. So, unless you are outdoors, make sure that your iPhone is not being used at too high of a brightness level. You can even set your iPhone to automatic brightness if you do not want to change the brightness again and again from the control center.

Delete all Widgets in your iPhone

With newer versions of iOS, iPhones got the functionality of using widgets on the home screen. These are great for using certain app functions right from your home screen. But for this ease of use, all the widgets on your iPhone need to stay running in the background. And as you would expect, this also causes high CPU usage while using your iPhone. Therefore, if you are facing iPhone overheating issues, try deleting all widgets from your iPhone and see if that fixes the issue.

Disable Background App Refresh on your iPhone

Another newer feature that you can find in iPhones is the background app refresh which is supposed to make your iPhone faster. This is done by allowing apps to refresh and get new information in the background. Although, to make this possible, your iPhone also uses the CPU quite a lot. Since it can also cause iPhone overheating, you should disable background app refresh on your iPhone as explained here:

  • You have to first go to the Settings app on your iPhone and open the General settings.
  • After that, go to the Background App Refresh settings, find the Background App Refresh option and turn it off.
  • Once done, you can restart your iPhone to check if the iPhone overheating issue is fixed or not.

Consult an Apple Genius Bar to Service your iPhone
