How to Reset Your iPhone to Factory Settings (The Fast, Safe Way)

Meta description: Learn to back up and reset any iPhone to factory settings fast. Step-by-step for iOS 17/18, Activation Lock, eSIM, iCloud, Finder, and recovery mode.

Whether you’re selling your phone, fixing a stubborn software bug, or starting fresh, a factory reset wipes your iPhone clean and restores it like new. This guide shows you the safest, quickest way to reset any iPhone—plus how to back up first, avoid Activation Lock issues, and handle eSIMs and paired devices. Follow along for a smooth, stress-free reset, optimized for the latest iOS versions.

Before you reset to factory settings: do these steps

Before you erase anything, make a complete backup. On-device iCloud backup is fast: go to Settings > [your name] > iCloud > iCloud Backup > Back Up Now and wait until it finishes. For a more comprehensive copy—including Health data and passwords—connect your iPhone to a Mac (Finder) or Windows PC (iTunes) and create an encrypted backup. Verify the backup completed successfully so you’re not starting from zero after the reset.

Next, prepare your accounts and services. Stay signed in to Wi‑Fi, then sign out of iMessage and FaceTime if you’re switching platforms, and unpair your Apple Watch via the Watch app so it creates a fresh Watch backup. If you plan to trade in or sell, disable Find My only during the erase flow—iOS will ask for your Apple ID password to remove Activation Lock; confirming it then prevents headaches for the next owner.

Finally, handle cellular and security details. If you use an eSIM, decide whether you’ll keep or remove it during the erase (iOS will prompt you). Ensure you know your Apple ID password and device passcode, plug in or charge above 50%, and capture critical app data like 2FA recovery codes. If you’re moving to Android, deregister iMessage later to avoid missing texts. These few prep steps save hours of friction after the reset.

How to reset any iPhone to factory settings quickly

The fastest on-device method: go to Settings > General > Transfer or Reset iPhone > Erase All Content and Settings. Review what will be deleted, then proceed. Enter your passcode and Apple ID password when prompted to turn off Find My and Activation Lock. Choose whether to keep or remove your eSIM, then confirm. Your iPhone will erase and restart; when you see the Hello screen, it’s ready to set up or pass on.

If you forgot your passcode or the phone won’t boot, use recovery mode with a computer. Connect your iPhone, then enter recovery mode (iPhone 8 or later: press and quickly release Volume Up, press and quickly release Volume Down, then press and hold the Side button until the recovery screen appears). In Finder or iTunes, choose Restore to erase and reinstall iOS. Afterward, you can restore from an iCloud or computer backup during setup.

Away from your phone? You can erase it remotely: sign in at iCloud.com > Find Devices, select your iPhone, then choose Erase iPhone. Once the wipe is complete, click Remove from Account to clear Activation Lock for the next owner. After any reset or restore, follow the setup assistant, connect to Wi‑Fi, sign in with your Apple ID, and restore your backup if you’re keeping the device.

FAQs (schema-friendly)

Q: Will a factory reset remove Activation Lock?
A: The reset process prompts for your Apple ID password to disable Activation Lock. If you don’t enter it, the phone will remain locked to your account. If you’ve already erased, remove the device at iCloud.com or appleid.apple.com > Devices.

Q: How long does a factory reset take?
A: The erase step typically takes 5–15 minutes, plus any time to reinstall iOS (if using recovery mode) and restore your backup. Large iCloud restores can take longer depending on Wi‑Fi speed.

Q: Can I reset without Apple ID or passcode?
A: You can erase via recovery mode with a computer, but you’ll need the Apple ID credentials to bypass Activation Lock during setup. Without them, the device remains unusable.

Q: What about eSIM when I erase?
A: During the erase flow, iOS lets you remove or keep your eSIM. If you’re selling or trading in, remove it. If you’re keeping the phone, you can keep it and re-activate during setup, or contact your carrier to transfer.

Q: Does a factory reset delete iCloud photos?
A: No—photos in iCloud Photos remain in your iCloud account. Erasing the device removes local copies. After setup, sign back into iCloud to resync your library.

Q: Best backup option: iCloud or computer?
A: For convenience, iCloud is easiest. For the most complete backup (including Health and Keychain), use an encrypted Finder/iTunes backup. Many power users do both for redundancy.

Q: I’m moving to Android—what else should I do?
A: Deregister iMessage to avoid missing SMS/MMS, export authenticator codes or add backup methods, and move photos via Google Photos or a computer transfer. Erase and remove the iPhone from your Apple ID when you’re done.

Q: Trade-in tips after reset?
A: After the Hello screen appears, confirm the device is removed from your Apple ID, wipe the exterior, include the charging cable if requested, and keep your proof of backup.
