Troubleshooting an iPhone 6s that’s overheating after the iOS 13 update 

Considering the onset of the symptoms, software-related factors including an iOS bug are more likely the underlying cause. To eliminate all possible triggers, carrying out the following procedures can help. 


First solution: Clear all background apps then reboot your iPhone.

Many cases of overheating problems are attributed to rogue apps. Apps that were left suspended or running in the background during a system update are more likely to end up in this state. When this happens, there’s a higher chance for them to affect the entire system functions and thus, random issues like overheating are likewise possible to occur. To eliminate this from the possible triggers, follow these steps to end or clear all background apps on your iPhone 6s:

  1. Double-press the Home button to pull up the Apps Switcher or Multitasking screen. This screen contains the previews/cards of all applications you’ve recently used and left running in the background.
  2. Tap and drag an app card/preview to the top-corner of the screen to close or end individual applications.

After clearing all background applications, reboot or soft reset your iPhone to dump errant files and temporary data that were accumulated from the recent update.

If your iPhone is still responsive, then you can carry out the usual reboot or soft reset. Otherwise, force restart your iPhone 6s with these steps:

  1. Press and hold the Home button and the Power button simultaneously for about 10 seconds.
  2. Then release both buttons when the Apple logo appears.

Allow your device to finish its boot-up sequence then use it as you normally do to see if it still overheats or not.

Second solution: Disable unused wireless features.

Wi-Fi, Bluetooth, cellular data, and location services are irrefutably essential iOS features especially when navigating through your iPhone. Nonetheless, keeping these features turned on also denotes a significant power consumption. Having said that, your iPhone has a higher tendency to heat up continuously and eventually overheat if you keep these features activated. For this reason, turning these features off when they’re not in use is likewise recommended especially if you’re trying to stretch your iPhone’s battery life. Doing so will also prevent possible occurrence of overheating problem on your device. 

These features can be turned off individually through your iPhone settings or from the control center. 

  • To disable Wi-Fi, just go to Settings-> Wi-Fi menu, then tap the switch to turn Wi-Fi off.
  • To disable Bluetooth, go to Settings-> Bluetooth menu, then tap the switch to turn Bluetooth off.
  • To disable Cellular data, go to Settings-> Cellular menu, then tap the switch to turn cellular/mobile data off.
  • To disable location services, go to Settings-> Privacy-> Location Services menu, then toggle the switch to turn the feature off. Doing so will stop apps from using location services anytime you use them.

Alternatively, you can pull up the control center and then tap the shortcut icons to disable the same features individually.

Another way to turn off wireless features at once is by enabling the Airplane Mode feature on your iPhone. Simply head on to your iPhone settings then toggle the Airplane Mode switch to turn the feature off.

Aside from disabling unused wireless features, adjusting display settings like limiting the use of screen animations can also aid in reducing battery usage. Rapid battery draining can also lead to overheating problem. 


Third solution: Update all apps on your iPhone.

You might have failed to set your apps to auto-update and that therefore resulted in some outdated apps causing conflicts to your iPhone’s power system, which eventually led to an overheating problem. To address this concern, manually check for and install pending app updates on your iPhone 6s with these steps:

  1. From your Home screen, launch the App Store.
  2. Locate and tap on your Apple ID profile icon on the upper-right corner of the screen.
  3. Scroll down to the Pending Updates section.
  4. Tap on Update All to install all pending apps updates.
  5. If you wish to check for the recently installed apps updates, scroll down to Updated Recently section.

Your phone must be connected to Wi-Fi internet for you to be able to update your apps. Don’t forget to reboot your iPhone after installing all app updates to ensure that all new software changes are properly implemented.

Fourth solution: Reset all settings to fix your iPhone 6s that’s overheating after iOS 13 update.

Incorrect settings as well as options that weren’t properly configured can also lead to similar issues. This is likely to occur if the recent iOS update overrides your phone’s system settings automatically. To clear this out, reset all settings on your iPhone 6s. Doing so will erase all your current settings, customization, update overrides and system preferences and then restore the original values without affecting the internal data. Just follow these steps whenever you’re all set to reset all settings on your iPhone 6s:

  1. From the Home screen, tap Settings.
  2. Select General.
  3. Scroll down and tap on Reset.
  4. Select the option to Reset all settings. This will erase all customized options and new settings overrides from the recent update, without affecting your iPhone data.
  5. Enter your device passcode if prompted to continue.
  6. Then tap the option to confirm that you want to reset all settings on your device.

Wait for your iPhone to finish resetting all settings and then restarts when done. After it reboots, enable individual features that you want to use on your phone again.


Fifth solution: Restore factory default settings on your iPhone 6s.

If the previous reset doesn’t solve the problem and your iPhone is still overheating, it may be because of some complex system flaws inflicted by the recent update. At this point, your next option would be a factory reset. You may need to erase everything from your iPhone system so you can set it up as new. If you wish to continue, back up all your iPhone data to iCloud or iTunes as you prefer. Then follow these steps to factory reset your iPhone 6s through settings:

  1. From the Home screen, tap Settings.
  2. Select General.
  3. Scroll down and tap on Reset.
  4. Select the option to Erase all content and settings. This will erase everything from your iPhone system including downloaded apps, customizations, and files stored on the internal memory.
  5. Enter your device passcode if prompted to continue.
  6. Then tap the option to confirm that you want to erase your iPhone.

If your iPhone eventually becomes unresponsive as it overheats, then you will need to use iTunes as an alternative since the above procedures wouldn’t be applicable. Just get either a Windows or Mac computer that has the latest version of iTunes software ready then follow these steps to start erasing and restoring your iPhone through iTunes:

  1. Open iTunes on your computer to begin.
  2. Then connect your iPhone to your computer using the Apple-supplied USB cable or Lightning cable.
  3. Select your iPhone 6s when it appears in iTunes.
  4. Then click the Restore [iPhone] button. If necessary, sign out from Find My iPhone before you can click the Restore button.
  5. Click Restore again when asked to confirm that you want to restore your iPhone 6s to its factory settings.

Your computer will then start erasing and installing the latest software version for your iPhone. When the restore is finished, your phone should restart. By then you can set it up as new.

Majority of software-related issues including those that have instigated from an iOS update are typically addressed by a factory reset. The same thing should happen if the overheating problem on your iPhone 6s is due to some system flaws.
