First solution: Reboot your iPhone 7 (soft reset).

A device would typically heat up when installing new update especially if the update file is too big. The bigger the file size is, the longer it would take for the processor to complete the download and installation process. This means more workloads for the processor to carry out. When the processor gets exhausted, the device heats up. Unless your iPhone gets extremely warm, just allow it to finish updating. When the update is complete, perform a soft reset or restart your iPhone to implement the recent changes accordingly and refresh the system. Here’s how:

  1. Press and hold the Power button until the Slide to Power off menu appears.
  2. Drag the slider to the right to power off your device.
  3. After 30 seconds, press and hold the Power button again until the Apple logo appears.

It’s a simulated battery removal procedure that works the same as a soft reset. Doing so forces all apps to close and the iOS to shutdown. Any software glitches that might have caused your device to misbehave will likewise be remedied.

Second solution: Manage and remove rogue apps.

Some apps, especially third-party apps may tend to become erratic after a new iOS platform is implemented. Either these apps no longer meet the minimum system requirements to run smoothly on the new platform or the new update might have some bugs that might have triggered apps to go rogue or prevented them from working as intended. To rule this out, try to check your iPhone’s battery usage details and see any usual data. Here’s how to access this setting:

  1. Tap Settings.
  2. Tap Battery.
  3. Navigate to the Battery usage section.
  4. Scroll down and see which apps are consuming much of your iPhone power.

If you see any unwanted apps on the top list, try to check if there are any available updates for that app. If there is, then update your apps to make it work smoothly with your iPhone’s new system structure. Otherwise, you might as well consider disabling or deleting the app instead. Apps that consume the most power are likewise the ones that are revving your iPhone’s processor thereby causing it to overheat eventually.

Third solution: Reset all settings on your iPhone 7.

As the name implies, this process will reset all the settings on your iPhone to their default or original values. Although this reset does not affect any data stored on the internal memory, it is still advisable to keep a backup for safekeeping.

To reset all settings on your iPhone 7, follow these steps:

  1. Navigate to Settings-> General menu.
  2. Scroll to and tap Reset.
  3. Enter your device passcode, if prompted.
  4. Select the option to Reset all settings.

Fourth solution: Perform a recovery mode restore.

If a factory reset failed to offer resolution, the next option you can try on is a recovery mode restore. As the name implies, this restores iOS on your phone in recovery mode. A robust computer with the latest iTunes software installed is required to carry out a recovery mode restore.

To get started, connect your iPhone to your computer using the supplied Lightning cable. Then open iTunes on your computer and wait until it recognizes your iPhone.

While your device is connected, force it to restart with these steps:

  1. Press and hold the Side/Power button and Volume Down button simultaneously. Don’t release the buttons when the Apple logo appears, instead keep holding them until you see the Connect to iTunes screen.
  2. When you’re prompted with the option to Update or Restore, select Restore.
  3. Follow the onscreen prompts to continue.
  4. Wait until iTunes is finished reinstalling iOS and downloads the software for your device.

If the download takes more than 15 minutes, your iPhone exits recovery mode. When this happens, just wait until the download is finished and then enter recovery mode again.

Once the Restore is finished, you can proceed with the initial setup process.

Fifth solution: Restore your iPhone 7 in DFU mode.

When nothing else is working, you may still continue to troubleshoot your iPhone and try your luck in a DFU mode restore. It puts your iPhone in a state where it’s still able to communicate with iTunes on a computer but without activating the bootloader or iOS. Here’s how it’s done:

  1. Close any open apps on your computer then connect your iPhone using the supplied USB cable or Lightning cable.
  2. Open iTunes on your computer. Make sure you’re using the latest version of iTunes to prevent system conflicts.
  3. Press and hold the Power button and Volume Down button simultaneously for 8 seconds.
  4. After the elapsed time, release the Power button but keep holding the Volume Down button for a few seconds more.
  5. Release the Volume Down button when iTunes prompts you with the “iTunes has detected an iPhone in recovery mode…” message.

Your iPhone screen will then become completely black. This means you’ve successfully entered DFU mode. You can now restore your iPhone in iTunes.

If you failed to enter DFU mode like when you see any logo instead of black screen after the last step, try again from the very start until you finally entered DFU mode.
