iPhone freezing and restarting

Hi Mo_Eltahawy,

To clarify, when it restarts, does it show the Apple logo or a spinning gear?

If it does, take a look at the tips here:

• If your iOS or iPadOS device restarts or displays the Apple logo or a spinning gear unexpectedly 

If your iPhone, iPad, or iPod touch unexpectedly restarts or shuts down, or displays the Apple logo or a spinning gear, learn what to do.

Check your software

Make sure that your device has the latest version of iOS or iPadOS and that your apps are up to date. If the issue continues after updating your software and apps, check your hardware.

Check your hardware

On an iPhone 6 or later, check your battery health under Settings > Battery > Battery Health.

If your battery doesn't need service, and your iPhone, iPad, or iPod touch continues to frequently restart or turn off, contact Apple Support.

If your apps quit unexpectedly, learn what to do.

If your device has a frozen screen, doesn't respond, or becomes stuck when you turn it on, learn what to do for iPhone, iPad, or iPod touch.

Should the issue persist, we'd advise following the steps here to reinstall iOS. Bear in mind this requires a computer, and make sure you select "Update" when prompted. Selecting Restore will delete your data.

"If your iPhone turns on but gets stuck during start up

If you see the Apple logo or a red or blue screen during startup, try these steps:

1. Connect your iPhone to a computer. On a Mac with macOS Catalina, open the Finder. On a Mac with macOS Mojave or earlier, or on a PC, open iTunes. Find out which macOS your Mac is using.
2. Select your iPhone on your computer.
3. While your iPhone is connected, follow these steps:

• On your iPhone 8 or later, including iPhone SE (2nd and 3rd generation): Press and quickly release the volume up button. Press and quickly release the volume down button. Then press and hold the side button.
• 
  
  • 
• On your iPhone 7 or iPhone 7 Plus: Press and hold the side button and volume down button at the same time.
  • 
  • On your iPhone 6s or earlier, including iPhone SE (1st generation): Press and hold both the Home button and the side button or the top button at the same time.

1. Keep holding the buttons until you see the recovery mode screen.
2. 
3. When you get the option to restore or update, choose Update.
4. 
5. Your computer will download the software for your device. If it takes more than 15 minutes, your device will exit recovery mode. Repeat steps 2-4."

Cheers!
