10 Tech How-To

How to Completely Reset an iPhone Safely

Guide 10-39662 · Updated · Step by step

A complete reset erases your iPhone’s personal data, settings, accounts, and downloaded apps, returning it to the setup screen. Before you begin, make sure you have a current backup and know the Apple Account password used on the phone; the steps below cover both preparing the device and erasing it.

What You’ll Need

  • Your iPhone and its passcode.
  • The password for the Apple Account signed in on the iPhone, if Find My or Activation Lock is enabled.
  • A recent iCloud or computer backup if you want to restore your data later.
  • A Wi-Fi connection and power, especially if you plan to back up or erase through iCloud.

Step-by-Step

  1. Decide whether you need a backup. Erasing removes the data stored on the iPhone. If you may want photos, messages, app data, or settings again, back up first. For an iCloud backup, connect to Wi-Fi, open Settings, tap your name, then iCloud > iCloud Backup > Back Up Now. Keep the phone connected until the backup finishes. Check the time of the latest backup on the same screen. Alternatively, back up to a Mac using Finder or to a Windows PC using the Apple Devices app or iTunes, depending on what is installed.
  2. Save anything that is not included in your backup. Check important photos, files, authenticator or messaging apps, and other app-specific information. Some services sync data separately; confirm it is synced or export it as the service recommends. A backup is not a guarantee that every app’s content can be restored.
  3. Prepare the phone if you are selling or giving it away. Unpair an Apple Watch from the Watch app if it is paired, and move your phone number or SIM/eSIM service as appropriate. Do not delete photos or contacts manually while signed in to iCloud if you intend to keep them: that can remove synced items from iCloud and your other devices. The erase process removes the local content.
  4. Open the erase controls. On the iPhone, open Settings > General > Transfer or Reset iPhone. Tap Erase All Content and Settings. Do not choose Reset from this menu if your goal is a complete wipe; reset options such as Reset Network Settings do not erase all personal content.
  5. Review what will be erased. Read the prompts. If asked, enter the iPhone passcode and then the Apple Account password to turn off Find My and remove Activation Lock. You may be offered a choice about keeping or erasing an eSIM. If you are keeping the iPhone and its phone service, follow the on-screen choice that preserves the plan. If you are transferring or selling it, arrange service transfer first and follow the carrier’s instructions; erasing an eSIM may require the carrier to activate it again.
  6. Confirm the erase. Tap the final confirmation to begin. Keep the iPhone connected to power if possible and let it finish without interruption. The screen may go dark or show an Apple logo and progress indicator. The process can take several minutes or longer, depending on the device and its contents.
  7. Check for the setup screen. When erasing is complete, the iPhone should show the “Hello” welcome screen. If you are keeping it, follow setup and choose to restore from an iCloud or computer backup when prompted. If you are handing it to someone else, leave it at the welcome screen rather than signing in again.

Common Mistakes

  • Confusing reset options with a full erase: Reset All Settings changes settings but does not remove all content. Use Erase All Content and Settings for a complete reset.
  • Starting without checking the backup: A backup that is old, incomplete, or tied to an account you cannot access may not help. Verify its date and account before erasing.
  • Forgetting the Apple Account password: The device may require it to disable Find My. Resolve account access before erasing, rather than assuming the passcode will be enough.
  • Removing synced data by hand: Deleting iCloud-synced contacts or photos before erasing can also delete them from other devices. Let the erase process remove the iPhone’s local data.
  • Overlooking the eSIM: Erasing an eSIM can interrupt service. Confirm whether to keep or remove it based on whether you are retaining the phone and what your carrier requires.

Tips

  • Make a fresh backup immediately before wiping, and check that it completed successfully.
  • Keep the phone charged and connected to reliable Wi-Fi for cloud tasks. Do not interrupt an erase once it has started.
  • If selling the phone, remove any physical SIM card after the erase and make sure it reaches the welcome screen. Do not give the buyer your passcode or account password.
  • If you are resetting to fix a software problem, try restarting and installing available iOS updates first. A full erase is more disruptive and may not fix a hardware fault.

Troubleshooting

Erase All Content and Settings is missing or unavailable: Check that you are in Settings > General > Transfer or Reset iPhone. A work or school management profile may restrict erasing; contact the organization’s administrator rather than trying to bypass its controls.

The iPhone asks for an Apple Account password you do not know: Use Apple’s account recovery process or contact the account holder. If the phone belongs to someone else, ask that person to remove it from their account. A reset does not remove Activation Lock, and setup cannot be completed without the required account authorization.

The phone is frozen or will not open Settings: Try a force restart using the button sequence for your iPhone model, then check whether Settings works. If it remains unresponsive, connect it to a Mac or Windows computer and use Finder or the Apple Devices app (or iTunes where applicable) to update or restore it. A restore erases the device; an update is intended to reinstall iOS without erasing, but back up first whenever possible.

The erase seems stuck: Give it time, particularly if a progress indicator is moving. If there is no change for an unusually long time, connect it to power and seek Apple Support guidance before repeating the process. Avoid repeatedly disconnecting or force restarting during an active erase.

It returns to an account lock during setup: The device is still associated with an Apple Account through Activation Lock. The previous account holder must remove it from their account; restoring the phone again will not clear the lock.

Frequently Asked Questions

Does a complete reset delete everything?
It removes local content and settings from the iPhone, including apps and personal data. Information synced or backed up elsewhere may remain in those services.

Will erasing my iPhone cancel my phone plan?
Not necessarily. Erasing the device and canceling or transferring cellular service are separate actions. Check with your carrier, especially before removing an eSIM.

Can I restore my data after a factory reset?
Yes, if you have a usable iCloud or computer backup, or data synced with your accounts. During setup, choose the relevant restore or sign-in option.

Does erasing turn off Find My?
The erase flow may ask for your Apple Account password to turn off Find My and remove Activation Lock. Confirm that the process completes; simply deleting data through a computer may not remove the account lock.

How long does a complete reset take?
It varies with the iPhone and its contents. Allow enough time for the erase and any backup beforehand, and keep the device powered while it works.

Can I reset an iPhone without its passcode?
You cannot normally erase it through Settings without the passcode. A computer restore may erase a locked iPhone, but Activation Lock can still require the Apple Account previously used on it.
