Tutorial – How to Factory Reset iPhone Using Settings

This is the standard method and the one most people should use. It works on modern iPhone models and erases your data, settings, apps, and accounts, returning the device to factory condition.

Step 1: Back up your iPhone first

Before you erase anything, make sure your data is saved somewhere safe. If you want to keep photos, messages, app data, or contacts, back up to iCloud or a computer first.

After the backup is complete, you should be able to confirm it in Settings under your Apple ID, or in Finder on a Mac, or iTunes on a Windows PC. Think of this like making a copy of your keys before changing the locks.

Step 2: Open the Settings app

Tap Settings on your iPhone’s Home Screen, then look for the main settings menu.

You should see a list of options with your Apple ID at the top. If you are not sure you are in the right place, the Settings app is the gray gear icon.

Step 3: Go to General

Tap General in the Settings menu.

On screen, you will see system-level options such as software updates, storage, and AirDrop. This section controls the iPhone’s deeper functions, including reset tools.

Step 4: Tap Transfer or Reset iPhone

Scroll to the bottom and tap Transfer or Reset iPhone.

This is where Apple places the erase and reset options on newer iOS versions. If you are looking for a factory reset, this is the menu you want.

Step 5: Choose Erase All Content and Settings

Tap Erase All Content and Settings.

Your iPhone will show a warning explaining that this will delete your data, apps, media, and settings. You may also see a summary of what will be removed, which is your last chance to stop and back up anything important.

Step 6: Enter your passcode and Apple ID password

Enter your device passcode when prompted, then enter your Apple ID password if asked.

This step confirms that you own the device and helps disable Find My iPhone and Activation Lock. If you skip this part or enter the wrong password, the reset will not continue.

Step 7: Confirm the reset and wait

Tap Erase iPhone or Continue to confirm.

Your iPhone will begin wiping data and may restart more than once. You should eventually see the Apple logo, followed by the setup screen that appears when the phone is fresh from the factory.

Step 8: Set up the iPhone again or leave it erased

When the reset finishes, you can set up the iPhone as new, restore from a backup, or turn it off if you are selling or giving it away.

If you are passing the phone to someone else, it is a good idea to leave it at the Hello screen. That tells you the reset completed successfully and the device is ready for a new owner.

Alternative Methods and Edge Cases

Not every iPhone reset situation is simple. Here are a few common variations and what to do in each case.

• If your iPhone is frozen or you cannot open Settings:
  
  Use a computer to reset the iPhone in Finder on Mac or iTunes on Windows. Connect the iPhone with a cable, put it in recovery mode if needed, and choose Restore.

  
  

• If you want to erase only content but keep some settings:
  
  iPhone does not offer a true partial factory reset. You can use Reset All Settings under Settings > General > Transfer or Reset iPhone > Reset, but that does not erase your data.

  
  

• If you are selling or trading in the iPhone:
  
  Sign out of Apple ID, turn off Find My iPhone, then erase the phone. This helps prevent activation issues for the next owner.

  
  

• If you forgot your passcode:
  
  You will likely need to use recovery mode with a computer to erase the phone. In that case, the iPhone is restored via Finder or iTunes rather than in Settings.

  
  

• If the iPhone is managed by work or school:
  
  A company or school may have restrictions that prevent a full reset or reactivation without IT approval.

  
  

Frequently Asked Questions

Will a factory reset delete everything on my iPhone?

Yes. A factory reset erases photos, messages, apps, account data, and most settings from the device.

Does factory resetting remove my Apple ID?

It removes the Apple ID from the iPhone only after you enter the correct password and complete the erase. If Find My iPhone is enabled, Activation Lock may still require your Apple ID to reactivate the phone.

Can I factory reset an iPhone without a passcode?

Usually, no, not from the device itself. If you forgot the passcode, you may need to erase the iPhone using a computer and recovery mode.

How long does a factory reset take?

Most resets take a few minutes, but the exact time depends on the amount of data on the phone and the iPhone model.

Can I undo a factory reset?

No, not once the erase is complete. You can restore data only if you made a backup before resetting.

What is the difference between Reset All Settings and Erase All Content and Settings?

Reset All Settings keeps your data but resets system preferences. Erase All Content and Settings wipes the iPhone completely.

Tips

• Back up first if there is anything you want to keep. A reset is permanent once it starts.
• If you are selling the iPhone, remove your SIM card after the reset if you do not plan to keep using it.
• Make sure the battery is charged or keep the phone plugged in during the reset process.
• Use Wi-Fi and your Apple ID credentials handy if you plan to set the device up again right away.
• If the iPhone is linked to your Apple account, check the Find My status before erasing. That can save you from activation problems later.

Troubleshooting

• If the reset option is grayed out, check whether Screen Time restrictions or device management settings are enabled.
• If the phone will not erase, restart it and try again. A simple reboot can clear temporary glitches.
• If you forgot your Apple ID password, reset it at Apple’s account recovery page before trying again.
• If the iPhone gets stuck on the Apple logo during reset, connect it to a computer and use recovery mode.
• If you cannot find Transfer or Reset iPhone, update iOS. Older versions may place reset options in a slightly different menu.
• If the phone keeps asking for Activation Lock after the reset, the previous Apple ID still needs to be entered, or Find My iPhone was not fully disabled.

Conclusion

Factory resetting an iPhone is one of the simplest ways to fix software issues, clear personal data, or prepare a device for a new owner. Once you know where the option lives in Settings, the process is fast and pretty painless.

Just remember the one rule that matters most: back up first if you want to keep anything. After that, a factory reset is a clean reset button for your iPhone, and now you know exactly how to use it.
