What Happens If You Reset Your iPhone: Full Guide

What happens if you reset your iPhone depends on whether you reset only its settings or erase all content and settings. A settings reset keeps personal data, while a full erase removes the data stored on the iPhone and returns it to factory settings.

Reset vs. Erase: What's the Difference?

“Reset” and “Erase All Content and Settings” are separate commands on an iPhone. Check which command is selected before confirming anything.

• Reset All Settings: Restores system preferences to their defaults without deleting photos, messages, apps, documents, or other personal data. It removes or resets items such as saved Wi-Fi networks, Bluetooth pairings, privacy choices, keyboard settings, Face ID or Touch ID settings, Apple Pay cards, and the Home Screen layout.
• Erase All Content and Settings: Removes personal information, apps, accounts, media, and settings stored on the iPhone. The phone then returns to the setup screen.

If you are asking what happens if you reset an iPhone to fix a connection or settings problem, Reset All Settings may be enough. If you need to remove a forgotten passcode, the iPhone must generally be erased.

What Happens to Your Data When You Erase an iPhone?

Erase All Content and Settings deletes the copies of photos, messages, apps, notes, contacts, files, and account information stored on the iPhone. Data that was never synchronized or backed up may be permanently unavailable after the erase.

Content already synchronized with iCloud is not deleted from iCloud merely because the iPhone is erased. It can appear again after you sign in with the same Apple Account and enable the relevant iCloud features.

• Photos and videos can return if they were synchronized with iCloud Photos or included in a usable backup.
• Messages can return from Messages in iCloud or an eligible backup.
• Notes and contacts can return if they were synchronized with iCloud or another account.
• Apps can be downloaded again, but their local data returns only if the app synchronized it or the data was included in a backup.
• Downloads, unsynchronized files, and data created after the latest backup may be lost.

A backup is a saved copy used to restore supported data and settings. Check its date before erasing so you understand how much recent information may be missing.

What Happens to Your Apple ID and Accounts?

Apple now calls an Apple ID an Apple Account, although many screens and instructions still use the older name. During a normal full erase, the iPhone may request the device passcode and Apple Account password, signs out of Apple services, and turns off Find My and Activation Lock.

Activation Lock is an anti-theft feature that links an iPhone to the Apple Account used with Find My. If the iPhone is erased through recovery mode without first removing that link, setup can still require the previously linked Apple Account and password. Erasing the phone does not bypass Activation Lock.

Email, social media, banking, and other online accounts are not deleted at their providers. Their sign-in details are removed from the iPhone, so you may need their passwords and verification methods when reinstalling apps.

What Should You Check Before Resetting an iPhone?

1. Make a current iCloud backup or a computer backup using Finder, Apple Devices, or iTunes, as appropriate for the computer.
2. Confirm that the backup completed and note its date. If using an encrypted computer backup, make sure you know its password.
3. Write down the Apple Account used on the iPhone and confirm that its password works.
4. Make sure you can receive any verification codes needed for Apple and other accounts.
5. If transferring ownership, sign out and ensure Find My and Activation Lock are removed as part of the erase process.
6. When asked about an eSIM, choose carefully. Deleting an eSIM may require help from the carrier to reactivate cellular service.

How Do You Reset an iPhone Step by Step?

To reset settings while keeping personal data:

1. Open Settings.
2. Select General.
3. Select Transfer or Reset iPhone.
4. Select Reset.
5. Choose the specific reset option, such as Reset All Settings or Reset Network Settings.
6. Enter the iPhone passcode and confirm if prompted.

To erase the iPhone completely:

1. Open Settings.
2. Select General, then Transfer or Reset iPhone.
3. Select Erase All Content and Settings.
4. Review the summary of content that will be removed.
5. Enter the device passcode or Apple Account password when requested.
6. Choose whether to keep or delete the eSIM if that choice appears, then confirm the erase.

What Happens If You Reset a Locked or Disabled iPhone?

A forgotten screen passcode cannot be removed with Reset All Settings. Resetting a locked or unavailable iPhone requires erasing its content, after which you can create a new passcode.

On a supported iPhone with a network connection and Find My already enabled, the Lock Screen may show Forgot Passcode? or an erase option. That process requires the linked Apple Account password. Another option is to place the iPhone in recovery mode, connect it to a Mac or Windows computer, and select Restore in Finder, Apple Devices, or iTunes.

Find My can also erase a device associated with your own Apple Account. Regardless of the erase method, data can be restored only from an available backup or synchronized account, and Activation Lock may still require the linked Apple Account credentials.

What Should You Expect After the iPhone Resets?

After a full erase, the iPhone restarts at the “Hello” screen. Follow the prompts to select a language and region, connect to a network, activate the device, and create a new passcode.

You can set up the iPhone as a new device or restore from an iCloud or computer backup. The erase itself may be relatively quick, but there is no fixed completion time. Activation, backup restoration, app downloads, and photo synchronization depend on the amount of data, connection speed, power, and Apple service availability.

Keep the iPhone connected to power and Wi-Fi while restoration continues. The Home Screen may become usable before every app, photo, message, and file has finished downloading.
