How to fix an iPhone 5c that's overheating

You can say that your iPhone is overheating if its temperature goes beyond the normal operating temperature range, which is between 32° and 95° Fahrenheit or  0° and 35° Celsius.  In normal circumstances, the device temperature gets back to normal after you let it cool down for a several minutes or hours. But that won’t be the case if overheating is attributed to other factors like system issues. There are actually many possible reasons as to why this happens and the underlying cause is either tied to the software or hardware. While most people think overheating problems in mobile devices are often due to a bad battery, several devices overheat due to some system flaws. Thus it is highly recommended to rule out software-related factors before rushing to a service center. Lined up below are suggested workarounds and potential solutions to the same problem on the Apple iPhone 5c device. Read on to find out what to do if your iPhone 5c is overheating before opting for service.

Troubleshooting an iPhone 5c that’s overheating

If it’s not a broken hardware, then something from within your iPhone software triggers the device to heat up so quickly or overheats. Carrying out each of the following procedures will help you eliminate individual factors or software components that might have caused your iPhone 5c to heat up so fast and overheat.

First solution: Clear all background apps then reboot the phone.

Rogue apps are usually the main reason why a device heats up and overheats. When apps go rogue, they could trigger the processor to work continuously until it gets exhausted. The more the processor operates, the higher the device temperature could become. Apps that usually go rogue are those that are left suspended or running in the background. Thus, clearing out all background should be considered among the first possible solutions to try. Here’s how it’s done:

  1. Double press the Home key to launch the recent apps screen. On this screen, you will see the previews of the apps you’ve recently used but not closed.
  2. Swipe up on each app card/preview to close or end individual apps.

After clearing all background apps, reboot/soft reset your iPhone to clear and refresh its memory and operating system. Just follow these steps to do so:

  1. Press and  hold the Power (Sleep/Wake) button on the top of the phone for a few seconds.
  2. Release the button when the Power Off slider appears. The iPhone will then shut down.
  3. After a few seconds, press and hold the Power (Sleep/Wake) button until the Apple logo appears and then release the button.

If the overheating problem result in your iPhone 5c screen becoming unresponsive or stuck, performing a forced restart would be necessary. Here’s how it’s done:

  1. Press and hold the Home button and the Sleep/Wake button simultaneously for about 10 seconds.
  2. Release both buttons when the Apple logo appears.

Allow your device to finish booting up and once it’s up, try to use it as you normally do and see if it still overheats. If it does, then you have to try other means to rule out other causing factors.

Second solution: Install pending app updates.

Another possible solution you should try is installing all pending app updates. These updates may contain the required fix patch to get rid of in-app bugs and malware that trigger apps or system functions to act up, which eventually results in overheating. If your iPhone has a stable Internet access, enough battery life and memory space, follow these steps to check and install all pending app updates available:

  1. Tap to open the App Store from your Home screen.
  2. From the App Store screen, scroll down to the bottom then tap the Updates tab. Doing so will open a new screen containing a list of apps with pending updates.
  3. To update individual apps, tap the Update button next to the name of an app.
  4. To update all apps at once, tap the Update All button on the upper-right side. This button is only visible of multiple app updates are available. 

If the overheating problem started after installing a new app, that app is more likely the trigger. To figure this out, try to disable the app and see how your iPhone behaves without the suspected app running. If it doesn’t overheat while the suspected app is disabled, then apparently, that app is the culprit and therefore needs to be deleted.

  1. Open the Settings app from your Home screen.
  2. Tap General.
  3. Then tap Storage & iCloud Usage.
  4. Navigate to the Storage section then tap Manage Storage.

Find the suspected app and then tap to select then delete the app from your phone.

Again, reboot the phone when finished installing app updates. Doing so will ensure that all new software changes are properly implemented.

Third solution: Update to the latest iOS version available.

If the problem isn’t resolved by installing app updates, try updating your iPhone software to the latest iOS version available. Software updates rolled out by Apple usually embed dedicated fix patches to get rid of bug-inflicted symptoms including overheating on your iPhone 5c. To check for and update your iPhone 5c wirelessly, simply follow these steps:

  1. Tap Settings from your Home screen.
  2. Scroll to and tap General.
  3. Tap Software Update.

Follow the rest of the onscreen instructions to download and install the update. Reboot the phone when you’re done updating and then see if that solves the problem.

Fourth solution: Reset all settings to fix your iPhone 5c that’s overheating.

Incorrect or settings that aren’t properly configured on the phone can also cause similar issues to occur and so they must also be eliminated. To clear out incorrect settings including automatic update overrides that caused your iPhone 5c to overheat, reset all settings with these steps:

  1. From the Home screen, tap on Settings.
  2. Tap General.
  3. Scroll to and tap on Reset.
  4. Select the option to Reset all settings.
  5. Enter your device passcode if prompted.
  6. Then tap to confirm that you want to reset all settings on your iPhone.

Wait for your iPhone to finish resetting and then reboots on its own. By then you can start enabling necessary features to use them again on your device.

Fifth solution: Erase your iPhone and set it up as new (factory reset).

You may have to consider wiping all data from your iPhone storage to eliminate stubborn bugs and complex system errors that caused overheating issue on your iPhone 5c. This can be deemed among the last options if the problem isn’t fixed by the previous methods. But before you do, back up all important files from your iPhone storage to iCloud or iTunes. Once the backup is secured, follow these steps to factory reset your iPhone 5c through settings:

  1. From the Home screen, tap Settings.
  2. Tap General.
  3. Select Reset.
  4. Tap Erase all content and settings from the given options.
  5. If prompted, enter your passcode to continue.
  6. Then tap to confirm that you want to erase your iPhone and restore factory defaults.

If your iPhone 5c becomes unresponsive or stuck as it overheats, performing a factory reset through settings may not be possible. As an alternative solution, you can use iTunes to manually erase and restore factory default settings on your iPhone. Here’s how:

  1. Open iTunes on the computer to get started. Be sure to use the latest version of iTunes app.
  2. Then connect your iPhone to the computer using the Apple-supplied USB cable/Lightning.
  3. Wait for iTunes to recognize your iPhone and starts syncing.
  4. Select your iPhone when it appears in iTunes.
  5. Click the button to Restore Backup.
  6. Locate the iOS backup file that you want to restore your iPhone from.
  7. Then click Restore.

Follow the rest of the onscreen prompts to finish the system restore process.

Last resort: Restore your iPhone in iTunes.

Restoring your iPhone from the previous backup can be deemed as the last option if your iPhone is still overheating after performing a factory reset. Performing iOS restore through iTunes in recovery mode or DFU is usually needed if the problem occurred from an iOS update and it’s not resolved. If you wish to troubleshoot further, then you can refer to these walkthrough on how to restore an iPhone 5c in recovery or DFU Mode.

Here’s how to put your iPhone 5c in recovery mode and restore from a previous iOS backup in iTunes:

  1. Turn off your iPhone, if it’s not already.
  2. While it’s powered off, press and hold the Home button then plug it into the computer. Make sure iTunes is already running on your computer.
  3. When you see the Connect to iTunes screen, release the Home button. 
  4. Your iPhone should now be in recovery mode. A few seconds later, you should see an iTunes message prompt saying that it has detected your iPhone in recovery mode and then allows you to restore your device. Just follow the onscreen commands to proceed.

Another type of iOS restore you can do in case a recovery mode restore still failed to resolve the issue is the so-called DFU mode restore.

  1. Turn off your phone, if it’s still turned on.
  2. While it’s off, connect it to the computer using the Apple-supplied USB cable/Lightning cable.
  3. Then press and hold the Home button and Power button simultaneously for about 8 seconds.
  4. After 8 seconds, release Power button but keep holding down the Home button until the iTunes prompt saying that it has detected an iPhone in recovery mode appears.
  5. Release the Home button as soon as you see the message prompt.

After doing so, your iPhone’s screen will become completely black. That means that you have successfully entered DFU mode and you can now start restoring your iPhone in iTunes.
