To erase an iPhone, go to Settings > General > Transfer or Reset iPhone > Erase All Content and Settings, enter your passcode, then your Apple Account password, and tap Continue. The phone restarts and wipes everything — apps, photos, messages, settings — back to factory condition in about two to five minutes. Just make sure you’ve backed up first, because once it’s erased, there’s no undo.
Before You Erase: The 2-Minute Checklist
Wiping a phone takes minutes. Rebuilding your digital life without a backup takes days. Do these three things first, in this order, and you won’t lose anything that matters.
Back up your data. The easiest path is iCloud: go to Settings, tap your name, then iCloud > iCloud Backup > Back Up Now, with Wi-Fi on and the phone plugged in. If your iCloud storage is full, back up to a computer instead — plug the iPhone into a Mac and use Finder, or a Windows PC with the Apple Devices app, and choose Back Up Now with the “Encrypt local backup” box checked so your saved passwords and health data come along too.
Sign out of everything you care about. On modern iOS, erasing with your Apple Account signed in handles most of this automatically, but it’s worth double-checking a few spots: banking and payment apps, two-factor authenticator apps (move those codes to your new phone first — losing authenticator access is one of the most painful mistakes people make), and any work apps your employer manages.
Write down your Apple Account password. The erase process asks for it to disable Activation Lock. If you’ve been signing in with Face ID for two years and can’t remember the password, reset it at support.apple.com before you start — a wiped phone still locked to someone else’s Apple Account is a very expensive paperweight.
Method 1: Erase Directly on the iPhone
This is the way most people should do it. You need your passcode and the phone needs to be charged (or plugged in).
- Open Settings and tap General.
- Scroll to the bottom and tap Transfer or Reset iPhone.
- Tap Erase All Content and Settings.
- If you see a “Finish Uploading Then Erase” or “Erase Now” prompt, choose the upload option so your latest iCloud backup completes.
- Enter your passcode, then your Apple Account password when asked.
- Tap Continue to confirm. The Apple logo appears and the phone restarts.
When it’s done, you’ll see the “Hello” setup screen in multiple languages. If you’re selling or trading in the phone, you’re finished — hand it over right there. Don’t sign back in during setup, or you’ll re-link the device to your account.
Method 2: Erase From a Mac or PC
This route is for when the screen is broken, the touch isn’t responding, or you can’t get past the lock screen. You’ll need the computer you’ve synced with before, or you’ll have to put the phone in recovery mode.
- Connect the iPhone to your computer with a cable.
- On a Mac with macOS Catalina or later, open Finder and select the iPhone in the sidebar. On Windows, open the Apple Devices app.
- Click Restore iPhone.
- Confirm, and the computer downloads the latest iOS and wipes the phone clean.
If the computer doesn’t recognize the phone, put it in recovery mode first: quickly press and release Volume Up, quickly press and release Volume Down, then press and hold the Side button until you see the recovery mode screen. The computer will then offer Restore as an option.
Method 3: Erase Remotely With Find My
Lost your phone, or left it somewhere you can’t get back to? Erase it from anywhere with a browser or another Apple device.
- Go to iCloud.com/find on any browser and sign in with your Apple Account — or open the Find My app on another Apple device.
- Select your iPhone from the device list.
- Click Erase This Device and confirm.
Two things to know about remote erase: it only works if the phone is online (if it’s off, the command queues up and runs the next time it connects), and erasing disables Find My location tracking for that device afterward. So if there’s any chance of recovering it, try Lost Mode first and keep erase as your nuclear option.
Why Are You Erasing It? Match the Method to the Reason
Not every situation calls for a full wipe, and the right choice saves you real time.
Selling or trading in
Full erase, always. Also remove the SIM card and any case, and unenroll from carrier financing apps if applicable. Carriers like Verizon, AT&T, and T-Mobile all accept wiped phones for trade-in credit — one still logged into your accounts is a security problem waiting to happen.
Fixing a misbehaving phone
Try the softer resets first: force restart, reset network settings (Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings). A full erase fixes stubborn software glitches — the kind where apps crash constantly or battery drains inexplicably — but restore your backup afterward instead of setting up as new, unless you suspect the backup itself is corrupted. If the real problem is an unwanted subscription quietly charging you, cancel the free trial in your App Store settings first — no wipe required.
Giving it to a family member
Erase it, but during setup choose to restore from your backup onto the new phone first, then wipe the old one. Handing someone a phone still full of your texts and photos is awkward for everyone.
Returning it to Apple or a retailer
Erase it and turn off Find My. Apple’s own trade-in program requires the device be removed from your account, and support articles at Apple Support walk through exactly what to disable before you ship it.
After the Erase: What Happens Next
A freshly erased iPhone behaves like a brand-new one out of the box. You’ll walk through language, Wi-Fi, and either restore from a backup or set up as new. If you restore from iCloud, expect the process to take anywhere from twenty minutes to a couple of hours depending on how much data you have — photos and videos are usually the slow part. Keep the phone on Wi-Fi and plugged in until it’s done.
One more detail people miss: your Apple Watch, if you have one, is unpaired during the erase. You’ll re-pair it during setup, ideally restoring from its backup too.
If you erased the phone remotely because it was lost and it later turns up, you can restore it from your last backup and it’s as if nothing happened — minus whatever was created between the backup and the erase.
A fresh setup is also the perfect moment to fix the little annoyances you’ve been living with — like turning off CarPlay if you never use it, or blocking calls from No Caller ID numbers for good.
FAQs
Does erasing an iPhone remove the Apple Account?
Yes — when you erase through Erase All Content and Settings and enter your Apple Account password, the device is removed from your account and Activation Lock is turned off. That’s exactly what a buyer needs. But note: erasing through recovery mode on a computer without your password does not remove Activation Lock, so the phone will still ask for your Apple Account during setup.
Will erasing my iPhone delete my iCloud data?
No. Your iCloud photos, contacts, and backups live on Apple’s servers, not on the phone, and they stay untouched. Erasing the phone only deletes what’s physically stored on the device. Your iCloud data remains available to sign into on any other device.
How long does it take to erase an iPhone?
The erase itself usually takes two to five minutes on modern iPhones. The iCloud backup beforehand is the variable part — a nearly full 256GB phone on slow Wi-Fi can take an hour or more to back up. Do the backup the night before if you’re in a hurry the next day.
Can someone recover data from an erased iPhone?
Practically speaking, no. Modern iPhones encrypt everything with keys stored in the Secure Enclave, and erasing destroys those keys. Without them, the remaining data is unreadable scrambled noise — even to sophisticated forensic tools. This is why Apple can confidently tell you the wipe is permanent.
Do I need to remove my SIM card before erasing?
It’s good practice, yes. The erase doesn’t affect the SIM, but if you’re selling or trading in the phone, take your physical SIM out (and transfer your eSIM to your new phone first). You don’t want your phone number going home with a stranger.
