iOS Erase All Content and Settings: What It Does

On an iPhone or iPad, Erase All Content and Settings removes personal data and restores the device to its setup screen; it does not delete your Apple Account or erase data already synced to iCloud. Before using it, make a backup and check what will happen to your eSIM, passcode, and Activation Lock, especially if you plan to give the device to someone else.

What Erase All Content and Settings does

This built-in reset removes locally stored personal information, settings, and apps, returning the device to the “Hello” setup screen. It is intended for situations such as selling, trading in, giving away, or starting fresh with an iPhone or iPad. The exact confirmation screens can vary with the device, iOS or iPadOS version, and whether particular services are configured.

Erasing the device is not the same as deleting everything associated with your Apple Account. Photos, contacts, notes, and other information that has already synced to iCloud remain in the account and can sync again when you sign in later. Likewise, content stored with other services is not necessarily removed from those services. An erase affects the device, not every copy of your information elsewhere.

It also does not cancel subscriptions, remove purchases from your account, or automatically delete your Apple Account. Those are separate actions. If you are keeping the device and want to fix a settings issue, consider a less destructive reset instead.

Back up and prepare first

Erasing is difficult to reverse if you have no backup. Check that anything important is either synced or included in a recent backup, and make sure you know your Apple Account password. If you use a passcode or have account security protections enabled, you may need to authenticate before the erase can proceed.

• Check iCloud sync: In Settings, tap your name and review iCloud settings. Confirm that important categories have finished syncing; a backup and iCloud syncing are related but not identical.
• Make a backup: Use iCloud Backup in Settings, or back up to a Mac or Windows computer. For a computer backup, encrypted backups can include additional sensitive information, such as saved passwords and Health data; keep the backup password safe.
• Prepare a replacement device: If you are moving to another iPhone, transfer or restore your information before erasing the old one. Verify that essential photos, messages, and files are available on the new device.
• Consider cellular service: If the device uses an eSIM, read the erase prompt carefully. You may be offered a choice to keep or delete the eSIM. For a handoff, follow the carrier’s instructions; deleting an eSIM can require contacting the carrier to set it up again.
• Unpair accessories where appropriate: If you are giving away an Apple Watch, unpair it through the Watch app on the iPhone first. This helps prepare the watch for a new owner and preserves a watch backup as part of the process.

Do not assume that seeing a backup date proves every item is safely recoverable. Check the backup destination, available storage, network connection, and sync status, and allow unfinished uploads to complete.

How to erase an iPhone or iPad

1. Open Settings.
2. Tap General, then Transfer or Reset iPhone (or Transfer or Reset iPad).
3. Tap Erase All Content and Settings.
4. Review the information and any choices shown, including options about an eSIM or cellular plan. Enter the device passcode or Apple Account password if requested.
5. Confirm that you want to erase the device and wait for the process to finish. Keep it connected to power if practical, and do not interrupt it.

On some versions or managed devices, labels and prompts may differ. If the option is unavailable or the device cannot open Settings, use Apple’s current instructions for erasing with a computer or restoring the device. A restore through a computer is a different route and may require recovery mode; it is not a way to bypass account protections.

Choose the right reset

Erase All Content and Settings is appropriate when you want to remove the device’s local user data, especially before handing it to another person. It is more extensive than resetting a preference, so it is usually not the first troubleshooting step for a minor problem.

• Reset All Settings: Resets settings without deleting your personal media, apps, or documents. You may need to configure preferences and network settings again.
• Reset Network Settings: Targets network-related settings and saved connections rather than wiping the device. Use it only when a network problem is the concern.
• Delete an individual app or file: Better when you only need to remove a particular item. Deleting an app does not necessarily delete its cloud-stored account data.
• Erase All Content and Settings: The broad, device-wide option for preparing a device for a new owner or starting over after backing up.

A frequent misconception is that “erase” means permanently deleting every copy of every file. In practice, it clears the device for setup, while cloud copies and backups can remain. Conversely, deleting a synced item while signed in may also remove it from other devices using the same sync service, so check whether you are deleting from the account or only resetting the device.

Giving the device to someone else

For a clean handoff, back up and transfer anything you need, then erase the device. When the erase completes, the setup screen should appear. If you are selling or giving it away, do not continue through setup with your own account; leave it at the greeting screen for the next owner.

Activation Lock is designed to prevent someone else from activating a device that is still linked to its owner’s account. Erasing alone may not remove that link in every situation. Follow the prompts to sign out or remove the device from your account as applicable, and verify the handoff instructions for your device and iOS version. Never share your account password with a buyer. A device that asks for the previous owner’s credentials during setup may still be linked to that account, and the new owner should contact the seller rather than try to bypass the lock.

If erasing does not work

If the erase option is missing, greyed out, or fails, first check for restrictions or device management. A work or school device may be supervised by an organization, which can limit changes; contact its administrator rather than attempting to remove management without authorization.

If Settings will not open or the device is unresponsive, connect it to a Mac or Windows computer and consult Apple’s instructions for updating or restoring that model. A computer restore can erase data too, so use it only after considering your backup. If the device is linked to an account, a restore does not remove Activation Lock. For forgotten passcodes, account-password problems, or persistent restore failures, use Apple’s official support and recovery guidance.

Frequently Asked Questions

Does Erase All Content and Settings delete my iCloud photos?
No. It erases the device, not the iCloud account. Photos that have synced to iCloud remain there, although they may no longer be available offline on the erased device.

Will erasing an iPhone remove the Apple Account?
It does not delete the Apple Account itself. Follow the sign-out and device-removal prompts when preparing a handoff, and check that Activation Lock will not prevent the next owner from setting up the device.

Should I remove or keep my eSIM?
For a device you are keeping, keeping the eSIM may avoid setting up cellular service again. For a transfer or sale, follow your carrier’s directions and read the erase prompt; deleting an eSIM can mean arranging a replacement with the carrier.

Can I recover data after erasing?
You can restore information from an available iCloud or computer backup, and synced data may return after signing in. Data that existed only on the device and was not backed up or synced may not be recoverable.

Does a factory reset fix every iPhone problem?
No. It can help when software or settings problems persist, but it will not fix hardware damage, carrier issues, or an account lock. Try a targeted reset or troubleshooting step first when a full wipe is unnecessary.
