Overheating issues usually occur following a new firmware update implementation as some apps go rogue following the system transition. Aside from rogue apps, settings that were overridden by the new platform are also among the underlying causes. Generally, the problem is attributed to software glitches and therefore rectifiable by end-users.

In iOS devices, overheating has seen been listed among the widespread issues following a new iOS update rollout. And it turns out that it still remains an issue even up to the present.

We may already have published articles that could help you with your problem.

First solution: Clear all background apps.

The apps that are first to go rogue from an update are those that are suspended or running in the background while updating. These apps may crash during the updating process. Unless they’re closed, there is tendency for them to affect the system operations and/or trigger the processor to constantly work until it gets exhausted. When this happens the device heats up and eventually overheats. To rule this out, follow these steps to clear all background apps on your iPhone XS:

  1. From the Home screen, swipe your finger up and then pause.
  2. Swipe right or left to navigate through apps preview.
  3. Then swipe up on an app preview to close apps individually.

Follow the same steps to clear all background applications.

Second solution: Force restart.

Forcing the iPhone to restart also helps if errant caches and corrupted data are the main culprits. Aside from apps cached files and temporary data may also become erratic. When this happens, adverse symptoms are triggered given that everything in the phone system is interrelated. And the simplest way to fix the problem is a force restart. Doing so will force any errant services and processes to end and the phone system to reboot. Here’s how to force restart your iPhone XS:

  1. Press and quickly release the Volume Up button.
  2. Then press and quickly release the Volume Down button.
  3. Finally, press and hold the Side/Power button until the Apple logo appears.

Just wait until the phone boots up then use it as you normally do and see if your iPhone XS still overheats.

Third solution: Install pending app updates.

If the problem continues after performing a force restart, then try to check for any pending app updates on your iPhone XS. The problem could be due to some outdated apps that are no longer able to work with the new platform. In that case, updating the app can help. App developers usually push updates soon before or after a new iOS version is released to keep their apps compatible and working with the latest iOS version. But if you haven’t set your apps to auto-update, there’s a chance that you’ve missed to install some updates, thus resulting to misbehaving apps. To make sure this isn’t the trigger, check for and manually update apps on your iPhone XS with these steps:

  1. Tap App Store from your Home screen. Doing so will launch the App Store main screen.
  2. Scroll down to and then tap the Updates section. A list of apps with pending updates then shows up.
  3. To update individual apps, tap the Update button next to the name of the app.
  4. To update all apps at once, tap the Update All button on the upper-right side of the screen. This option only becomes visible if multiple pending app updates are available.

Wait until all apps are finished updating and then reboot your iPhone XS to apply the recent changes to your apps and likewise to refresh your iPhone system.

Fourth solution: Reset all settings.

As mentioned earlier, some settings are automatically overridden by some updates. And this could result to either good or bad outcomes. If the settings override tends to push certain apps to constantly run, sync, or process other tasks even when idle, then that will eventually trigger the iPhone processor to become exhausted. As a result, the device can overheat at some point. To rule this out, wiping all customized settings and restoring the default options and original configuration can help. Here’s how it’s done:

  1. Tap Settings from the Home screen.
  2. Select General.
  3. Scroll down and tap on Reset.
  4. Select the option to Reset all Settings.
  5. Enter your device passcode, when asked to proceed.
  6. Then tap the option to confirm settings reset.

This reset does not affect any saved data on the internal memory, so all of your personal contents remain intact. Once the reset is finished, your iPhone reboots by itself. At that point, you can enable only the necessary options to use them again on your device.

Fifth solution: Restore iOS through iTunes.

This can be deemed among the last options and possible solutions to try if your iPhone XS is still overheating after applying the previous methods. This process may erase some of your contents, thus creating backups is recommended. You can back up all your important files to iCloud or iTunes before restoring your iPhone XS in iTunes with these steps:

  1. Plug your iPhone XS into your computer’s USB port using the supplied USB cable or Lightning cable.
  2. Open iTunes on your computer.
  3. Wait for iTunes to recognize and connect to your iOS device.
  4. Once connected, click on the iPhone icon on the left side of iTunes menu.
  5. Next, click the Restore button. You may choose to Back Up your important files from the iPhone to your computer drive.
  6. If prompted with iTunes to Restore the iPhone and wipe all data and settings from the device, click the Restore button to confirm.
  7. Then wait for iTunes to erase then download and restore the software for your iPhone.
  8. If prompted, select the option to Set Up as a New iPhone then follow the onscreen instructions to set up your iPhone XS based on your preferences.

Wait until the system is restored then reboot your iPhone XS to dump junk files and errant temporary data from the internal memory. Try and see if that fixes the problem. If your iPhone XS is still overheating after performing an iOS restore, then you’re probably dealing with some fatal system error that requires firmware repair.
