iphone 11 ios 18.3.2 battery screen off problem

hi,

To do a DFU (Device Firmware Update) restore on an iPhone, here’s a simple step-by-step guide:

What You'll Need:

• A computer (Mac or Windows)
• A USB cable to connect your iPhone to the computer
• The latest version of iTunes or Finder (on macOS Catalina and later)

Steps to DFU Restore Your iPhone:

1. Connect your iPhone to the computer via USB.
2. Open iTunes (or Finder if you’re using macOS Catalina or later).
3. Put your iPhone into DFU mode:

• iPhone 8 or later:
• Press and release the Volume Up button.
• Press and release the Volume Down button.
• Press and hold the Side button until the screen goes black (about 10 seconds).
• While holding the Side button, press and hold the Volume Down button for another 5 seconds. Then, release the Side button but keep holding the Volume Down button for about 10 more seconds.
• The screen should stay black, and iTunes (or Finder) will pop up saying it has detected an iPhone in recovery mode.
• iPhone 7 and 7 Plus:
• Press and hold the Power button and Volume Down button at the same time for about 10 seconds.
• Release the Power button but keep holding the Volume Down button for about 10 more seconds.
• iPhone 6s and earlier:
• Press and hold the Home button and Power button at the same time for about 10 seconds
• Release the Power button but keep holding the Home button for another 10 seconds.

1. Restore the iPhone:

• In iTunes or Finder, you’ll see a message saying that a device in recovery mode has been detected.
• Click Restore iPhone.
• Follow the on-screen instructions to complete the restore process.

That’s it! Your iPhone will now restore to factory settings and reinstall the latest iOS version. Make sure you have a backup if you need to restore your data afterward.
