What Does Resetting an iPhone Actually Do

Resetting an iPhone can either restore selected settings to their defaults or completely erase the device, depending on the option you choose. Reset All Settings keeps personal files, while Erase All Content and Settings removes photos, apps, messages, accounts, and other personal data from the iPhone.

If you are asking “what does reset your iPhone do,” the important point is that “reset” is not one single action. Read the confirmation screen carefully before entering your passcode.

What types of iPhone reset can you choose?

An iPhone offers several reset options, and each has a different result:

• Reset All Settings returns system preferences to their defaults. It does not delete your photos, messages, apps, documents, or other media.
• Erase All Content and Settings removes personal information, content, and settings and returns the iPhone to factory settings.
• Reset Network Settings removes saved network settings, including previously used Wi-Fi networks and passwords and VPN settings not installed by a configuration profile or device-management system.
• Reset Keyboard Dictionary removes words that you added by rejecting the iPhone’s suggested spelling.
• Reset Location & Privacy returns location-service and privacy permissions to their defaults.
• Reset Home Screen Layout restores the original arrangement of built-in apps without deleting apps.

There is no general “password reset” option in this menu. Apple Account passwords, the device passcode, Screen Time passcodes, and saved Wi-Fi passwords are different credentials and must be handled separately.

What does Reset All Settings change on an iPhone?

Reset All Settings clears or restores preferences while leaving personal data and media in place. Apple says the affected items include network settings, Wi-Fi passwords and connections, Bluetooth pairings, Apple Pay cards, Apple Watch pairings, Face ID or Touch ID settings, privacy choices, location preferences, notification settings, accessibility settings, the keyboard dictionary, wallpaper, and the Home Screen layout.

You may need to reconnect to Wi-Fi, pair Bluetooth accessories and an Apple Watch again, set up Face ID or Touch ID, add payment cards again, and review app permissions. Apps and their stored data remain installed.

What gets erased or kept after an iPhone reset?

What an iPhone reset does depends entirely on the selected command:

• Reset All Settings keeps: photos, videos, music, contacts, calendars, messages, call history, apps, app data, documents, downloaded content, and other personal files.
• Reset All Settings changes: system preferences, wireless connections, biometric settings, privacy permissions, paired devices, and other settings listed on Apple’s confirmation screen.
• Reset Network Settings keeps: photos, apps, messages, accounts, and other personal content. It removes saved network information and disconnects the current Wi-Fi connection.
• Erase All Content and Settings removes: personal information, apps, messages, photos stored on the device, accounts, and settings. The iPhone restarts at the Hello setup screen.

Data already synchronized with iCloud is not the same as data stored only on the iPhone. After an erase, synchronized information may return when you sign in and enable synchronization again. A backup can restore supported content and settings, but anything that was neither synchronized nor backed up may be permanently lost.

Does resetting an iPhone remove the passcode or Apple ID sign-in?

Reset All Settings requires the device passcode to authorize the action, but it is not the procedure for removing a forgotten device passcode or resetting an Apple Account password. It resets Face ID or Touch ID enrollment, so you will need to configure biometric unlocking again.

Reset Network Settings removes saved Wi-Fi passwords, but it does not erase the iPhone or serve as an Apple Account password reset.

Erase All Content and Settings removes the device’s data and settings, including the existing device-passcode configuration. Apple may require both the device passcode and Apple Account password before the erase can proceed. Afterward, you set up the iPhone again and create a new passcode.

Erasing an iPhone does not provide a way around Activation Lock, which links a protected device to its owner’s Apple Account. Only use the Apple Account belonging to you or follow Apple’s official account-recovery process.

What should you do before resetting an iPhone?

1. Check when the latest iCloud or computer backup completed. Create a current backup if you might need your data or settings again.
2. Confirm that you know the iPhone passcode and Apple Account password. Do not begin an erase while unsure whether you can sign in again.
3. Check whether important photos, messages, documents, authenticator records, and app data are included in the backup or synchronized elsewhere.
4. If the iPhone is leaving your possession, follow Apple’s official preparation instructions, including signing out and handling Find My or Activation Lock correctly.
5. Review the eSIM choice shown during an erase. The iPhone may let you keep or delete an eSIM; deleting it can require help from the carrier to reactivate cellular service.

A completed reset has no Undo button. After Reset All Settings, you can manually reconfigure preferences or restore an appropriate earlier backup. After an erase, recoverable information must come from a backup or a synchronization service.

How do you reset an iPhone from Settings?

On a current iPhone, use these steps:

1. Open the Settings app.
2. Select General.
3. Select Transfer or Reset iPhone.
4. For a settings-only action, select Reset and then choose the specific reset option.
5. For a factory reset, select Erase All Content and Settings.
6. Read the summary on the screen, then enter the requested passcode or Apple Account password and confirm only if the listed result is what you intend.

The wording can vary slightly by iOS version or device management. If the menu is missing or restricted, the iPhone may have Screen Time or organizational management controls.

Where can you get help if an iPhone reset goes wrong?

Open {site} and choose iPhone support for official guidance about resets, forgotten passcodes, disabled devices, backups, and Apple Account access. Apple’s support flow can also direct you to available live-support options after you select the problem.

If the iPhone shows Security Lockout or iPhone Unavailable, use Apple’s documented recovery process. Recovering from a forgotten passcode normally requires erasing the device; Apple Support cannot disclose or bypass a passcode or Activation Lock.

Never give anyone your Apple Account password, device passcode, or two-factor authentication code. Apple states that its support representatives do not ask customers to provide those secrets.
