How to fix an iPhone that keeps turning on and off without using its software?

When you are not able to use your iPhone that keeps restarting, it is impossible to fix its software glitches or firmware bugs. So try these fixes to stop your iPhone from turning off without using software settings.

1. Perform the Hard or Factory Reset

You can hard restart your iPhone using its physical buttons when you are unable to use your iPhone’s settings. With the changeable versions of iPhones the procedures of hard or factory reset changed over time as well. However, all are mentioned below step by step!

To force restart an iPhone 6, iPhone 6s PLUS or iPhone SE (first-gen):

  • Long press and keep holding the power button and home button at the same time.
  • Wait until the Apple logo appears on the screen and release pressing after that.

To force restart an iPhone 7 or iPhone 7 PLUS:

  • Press the volume down and the power button at once and keep pressing them until the apple logo appears on your iPhone’s screen.
  • Then release all the buttons and wait and check if your iPhone automatically restarts. That’s the sign of a successful reset.

To force restart an iPhone 8 or newer devices:

  • Press and quickly release the volume up button, then do the same with the volume down button as well.
  • Next press and hold the power button and keep holding it until the apple logo appears on the screen.
  • Lastly release it and wait to see if your phone restarts on its own.

After a successful hard or forced reset of your iPhone, it is expected to solve many issues of the device. Unfortunately, if it does not, then try out our next solutions.

2. Remove your SIM Card

Sometimes a broken SIM card may cause connection issues with the phone’s carrier, provoking it to randomly restart. Though this is very rare. But you can have a try by removing your iPhone’s SIM card and check whether it stops entering the booting loop. If it stops restarting randomly, then put the SIM card back and check the mobile or cellular connection.

3. Restore your iPhone using iTunes

If the hard reset has not solved your problem, it’s time to restore your iPhone using iTunes. Restoring an iPhone can solve critical system errors and the iPhone random restarts are one of them. 

To restore your iPhone using iTunes:

  • Connect your iPhone with your trusted computer or laptop using a USB cable (apple).
  • Press the Volume Up button of your iPhone and quickly release it. Then press and quickly release the Volume Down button as well.
  • Now long press and keep holding the Power Button until the Connect to iTunes Screen message pops up on the screen.
  • When you see the options to restore the iPhone, tap on the Backup option before you restore your device. You can restore your phone without backing up as well, but having backup is the best idea.
  • Then click on Restore and follow the instructions shown on your screen.

4. Use third-party iOS Repair Tools

In case the iTunes app fails to restore your faulty iPhone, you can use other non-apple third-party restoring software such as Dr. Fone – Repair, iMyFone iOS System Recovery, and many other software available at the apple store. But you have to be very picky to find the best third-party software. You need to check out the ones that would be the most compatible with your iOS version and computer. You better check others’ reviews before starting to use the software as well.

After being sure about the one convenient software for your iPhone, you need to download and install it on your computer. Then connect your iPhone with your computer and start the restoring process, probably much similar to the previous ones like iTunes. 

5. Enable the DFU Mode

The Device Firmware Upgrade or DFU mode is an amazing way to fix many internal bugs by doing the deepest system restore in your iPhone. Enabling the DFU mode varies from device to device and here’s how you can do that to solve your iPhone’s continuous turning off problem:

To enable the DFU mode manually on iPhone 6 or iPhone 6s PLUS or earlier devices:

  • Continuously press and hold the home and power button at once for about 8-10 seconds
  • Then release the power button and continue holding the home button for about 5 seconds more.

Enabling the DFU mode on iPhone 7 or 7 PLUS devices:

  • Press and hold the power button and volume down button continuously for 8-10 seconds at once.
  • Release the power button but continue pressing the volume down button for 5 seconds more.

For Phone 8 and earlier versions of iPhone:

  • Connect your iPhone with computer or laptop devices.
  • Press the volume up button first and quickly release it. And immediately, press the volume down button and release it quickly as well.
  • Then press and hold the power button and wait until the screen turns black.
  • Long press the volume down and power button at the same time for about 5 seconds.
  • Release the power button only but keep pressing the volume down button for 5 seconds more.

If a black screen appears, then the DFU mode is successfully enabled. Now iTunes will detect your device as in recovery mode. In order to exit from the DFU mode, simply restart your phone or go for the force restart, as mentioned above.
