How to Erase iPhone Data Before Selling

a handoff of an iPhone in miami

Erasing your iPhone before selling it is the single most important thing you can do to protect your privacy and maximize your payout. An iPhone still linked to your Apple ID can’t be activated by the buyer, which means they can’t use it, which means they’ll pay far less for it or not buy it at all. An iPhone that’s fully wiped, signed out of iCloud, and showing the Hello setup screen is worth significantly more than one that’s still locked to your account.

This guide walks through every step: backing up your data, signing out of your Apple ID, factory resetting the phone, and preparing it physically for the best offer.


Step 1: Back Up Your Data First

Before doing anything else, make sure everything you want to keep is safely saved. Once you erase the iPhone, your local data is gone permanently.

iCloud Backup: Connect to Wi-Fi, then go to Settings → [Your Name] → iCloud → iCloud Backup → Back Up Now. Wait for the backup to complete. You’ll see a “Last Backup” timestamp when it’s done. Make sure your photos, contacts, messages, and app data are all included.

Computer Backup: Connect your iPhone to a Mac (Finder) or PC (iTunes). Select your iPhone and click Back Up Now. Enable “Encrypt local backup” to preserve passwords and Health data in the backup.

Photos: If you use iCloud Photos, make sure it’s fully synced before erasing. If you use Google Photos or another service, verify your library has uploaded everything.


Step 2: Sign Out of Your Apple ID (This Removes Activation Lock)

This is the most critical step. Signing out of your Apple ID disables Find My and removes Activation Lock, the security feature that prevents a new owner from setting up the iPhone. Without completing this step, the buyer receives a phone they can’t activate.

Go to Settings → [Your Name] and scroll all the way to the bottom. Tap Sign Out. Enter your Apple ID password when prompted. You’ll be asked if you want to keep a copy of certain data on the device. Since you’ve already backed up, toggle these off and tap Sign Out to confirm. This automatically turns off Find My iPhone.


Step 3: Erase All Content and Settings

After signing out of your Apple ID, go to Settings → General → Transfer or Reset iPhone → Erase All Content and Settings. Enter your device passcode if prompted. The iPhone will erase everything and restart. This takes 5-10 minutes. When complete, the iPhone shows the “Hello” setup screen in multiple languages, meaning it’s fully wiped and ready for a new owner to activate with their own Apple ID.


Step 4: Remove Your SIM Card

Use the SIM eject tool (or a small paperclip) to remove your nano-SIM from the SIM tray on the side of the phone. Keep your SIM to use in your next device or to transfer your number. Leave the empty SIM tray in the phone so it’s complete for the buyer. Note: iPhone 14 and newer in the US are eSIM-only and don’t have a physical SIM tray, so nothing to remove for those models.


Step 5: Clean and Prepare the Phone Physically

Remove the case and screen protector. Old or cracked screen protectors make the phone look worse even if the screen underneath is perfect. Remove them so the buyer can see the actual screen and body condition.

Wipe the display and back glass with a dry microfiber cloth. Clean the camera lens. Clear any dust or lint from the charging port and speaker grills using compressed air or a soft brush.

Check your battery health under Settings → Battery → Battery Health. Know your percentage before coming in. Phones with 85%+ battery health get the best offers. Below 80% reduces the offer because buyers factor in battery replacement cost.

Bring the phone with a full or near-full charge so the buyer can power on and test it immediately during evaluation.

Gather accessories: original Lightning or USB-C cable, charger, and original box if you have them. These add a small amount to the offer.


Frequently Asked Questions

What if I forgot my Apple ID password?

You need to recover your Apple ID before selling. Go to iforgot.apple.com to reset your password. Once you can sign in, follow the steps above. Don’t sell an iPhone with Activation Lock still active, as it will dramatically reduce or eliminate the offer.

Does erasing the iPhone delete my iCloud data?

No. Erasing the iPhone removes data from the device but does not delete your iCloud account or the data stored in it. Your photos, contacts, and messages will all still be accessible on your next iPhone after you sign in to your Apple ID.

What if my phone won’t turn on and I can’t erase it?

You can remove your device from your iCloud account remotely. Go to icloud.com/find, sign in to your Apple ID, select your iPhone in All Devices, and click Erase iPhone, then Remove from Account. This remotely wipes the device and removes it from your account so the buyer can activate it.
