Tutorial – How to Erase an iPhone Using Settings
This method fully wipes the iPhone and returns it to factory settings. It removes your apps, photos, messages, accounts, and personal data, which is ideal before selling, trading in, or starting over with a clean device.
Step 1: Back up your iPhone first
Before you erase anything, save your data with iCloud or a computer backup so you can restore it later.
Go to Settings > [your name] > iCloud > iCloud Backup, then tap Back Up Now if you want to use iCloud. If you prefer a computer, connect your iPhone to a Mac or PC and create a backup in Finder, Apple Devices, or iTunes depending on your setup.
Step 2: Sign out of your Apple Account if you are giving away the phone
If the iPhone is not staying with you, signing out helps remove Activation Lock and prevents the next person from getting stuck at setup.
Open Settings, tap your name at the top, then scroll down and tap Sign Out. You may be asked to enter your Apple Account password. After that, the screen should return to the main Settings page with your name removed.
Step 3: Open the reset menu
Now go to the erase controls built into iPhone.
Tap Settings > General > Transfer or Reset iPhone. On older versions of iOS, you may see Reset instead of Transfer or Reset iPhone. The screen should show reset options, including the erase option at the bottom.
Step 4: Tap “Erase All Content and Settings”
This is the step that actually starts the factory reset.
Tap Erase All Content and Settings. Your iPhone may show a warning explaining that it will remove data, settings, and media. If you use eSIM, you may also see a prompt asking whether to keep or erase your cellular plan.
Step 5: Enter your passcode and Apple Account password
Apple asks for these details to confirm that you really want to wipe the device.
Type your iPhone passcode when prompted. If Find My iPhone is enabled, you may also need to enter your Apple Account password. After you confirm, the erase process begins, and the screen will usually dim or show an Apple logo.
Step 6: Wait for the iPhone to erase and restart
The phone needs a few minutes to finish wiping everything and reboot.
You will usually see the Apple logo and a progress bar. When it’s done, the iPhone will restart and show the Hello setup screen, which means the erase worked. At that point, the phone is ready to set up again or hand over to someone else.
Alternative Methods and Edge Cases
Erase an iPhone remotely with Find My
If your iPhone is lost, stolen, or you cannot access it, you can erase it from another device.
- Go to iCloud.com/find or open the Find My app on another Apple device.
- Select your iPhone from the list.
- Choose Erase This Device.
This sends the erase command the next time the phone connects to the internet. If you later recover the device, it will still need your Apple Account to activate.
Use a Mac or PC if the iPhone is frozen or won’t turn on normally
If the screen is stuck or the software is badly damaged, a computer restore may be the better option.
- Connect the iPhone to a Mac or PC.
- Put it into Recovery Mode.
- In Finder, Apple Devices, or iTunes, choose Restore.
This erases the device and installs a fresh copy of iOS. It is useful when the normal Settings method does not work.
Erase only your data, not your Apple Account
Sometimes people want a clean phone but still plan to keep using the same Apple Account.
You can erase the iPhone through Settings and then sign back in during setup. If you are keeping the phone, remember that your iCloud content can be restored later if you made a backup.
Delete a work or email account without wiping the whole phone
If your goal is just to remove one account, you do not need a full erase.
- Go to Settings > Mail > Accounts.
- Select the account.
- Tap Delete Account.
This removes mail, contacts, and calendar sync for that account without touching the rest of the iPhone.
Frequently Asked Questions
Will erasing my iPhone delete everything?
Yes. A full erase removes apps, photos, messages, account data, settings, and other local content on the device.
Will my iCloud data be deleted too?
Not usually. Erasing the iPhone deletes data on the device, but iCloud content stays in your Apple Account unless you delete it separately.
Do I need to turn off Find My iPhone before erasing?
Not always, but it helps. If you are selling or giving away the phone, signing out of your Apple Account and turning off Find My is the cleanest way to avoid Activation Lock issues.
Can I erase an iPhone without the passcode?
Not through the normal Settings method. If you forgot the passcode, you typically need to use Recovery Mode and restore the phone with a computer.
How long does it take to erase an iPhone?
Most iPhones finish in a few minutes, but the time can vary depending on storage size and device condition.
Can I undo an erase?
Only if you have a backup. Once the erase is complete, the deleted data is permanently removed from the iPhone.
Tips
- Back up before you wipe. A backup is your safety net if you want to recover photos, messages, and app data later.
- If you are selling the phone, remove your SIM card or, if needed by your carrier, transfer your eSIM first.
- Make sure the battery is charged or keep the iPhone plugged in during the erase process.
- If the phone is for someone else, stay on the Hello screen after the erase, do not sign it back in.
- If you use two-factor authentication, keep your trusted phone number handy in case Apple asks for verification when signing out.
- For business or school devices, check with your IT admin first, since management profiles can affect reset options.
Troubleshooting
- If Erase All Content and Settings is missing, update iOS or look under Settings > General > Transfer or Reset iPhone. Older iOS versions use different menu names.
- If the iPhone asks for an Apple Account password you do not know, you may need to recover the account before the erase can continue.
- If the phone freezes during the erase, force-restart it and try again, or use a computer to restore in Recovery Mode.
- If Activation Lock appears after the reset, the previous Apple Account is still linked. Sign in with that account or remove the device from Find My at iCloud.com.
- If you cannot erase from the phone because it is broken or unavailable, use Find My on another device or erase it remotely through iCloud.
- If your cellular plan is still active after the wipe, contact your carrier to confirm whether your eSIM or SIM needs to be deactivated separately.
Conclusion
Erasing an iPhone is simple once you know where to look. In most cases, the whole job takes just a few taps in Settings, plus a short wait while the phone resets itself.
If you back up first and sign out properly, you can wipe the device with confidence. Whether you are troubleshooting a problem, protecting your privacy, or preparing the phone for its next owner, a full erase gives you a fresh start the right way.
