You’re staring at a screen that’s frozen for the third time today. Or maybe you finally caved and bought the new titanium model, and your old phone is sitting on the kitchen counter, waiting to be shipped off to a stranger on eBay. Either way, you're here because you need to reset the iphone to factory settings. It sounds simple. It’s a button press, right? Well, mostly. But if you mess up the sequence, you’re looking at a locked device that nobody can use, or worse, losing ten years of photos because you thought the cloud had your back when it actually didn't.
Honestly, the "factory reset" is the nuclear option. It wipes everything. It returns the software to the exact state it was in when it left the assembly line in Zhengzhou.
The Pre-Reset Panic: Don't Skip This
Before you go nuclear, you have to talk about iCloud. Most people think they're backed up. They aren't. Go into your settings, tap your name, and look at that storage bar. If it’s in the red, your last backup was probably three weeks ago. That’s a lot of lost text messages.

First, unpair your Apple Watch. People forget this constantly. If you don't unpair it through the Watch app first, the watch stays "married" to a phone that no longer exists in a functional state. It’s a headache to fix later.
Then, there’s Find My. Since iOS 7, Apple has used something called Activation Lock. It’s a brilliant theft deterrent, but it’s a nightmare for legitimate sellers. If you reset the iphone to factory settings without signing out of Find My/iCloud first, the phone remains tethered to your Apple ID. Even after a full wipe, the next person who turns it on will see a screen asking for your password. If you’re selling to a trade-in site like Gazelle or Back Market, they will literally mail the phone back to you (or deduct $200 from the price) because they can't refurbish a locked device.
How to Actually Reset the iPhone to Factory Settings
Apple changed the menu layout in recent versions of iOS, just to keep us on our toes. You won't find the "Reset" button under "General" immediately anymore. It’s tucked away at the bottom.
Navigate to Settings, then General, and scroll all the way down to Transfer or Reset iPhone.
You'll see two choices here. "Reset" and "Erase All Content and Settings." These are not the same thing. Not even close. "Reset" is the soft version—it just messes with your settings, like your WiFi passwords or your home screen layout. It doesn't delete your data. To truly reset the iphone to factory settings, you must tap Erase All Content and Settings.
The phone will then give you a summary of what’s about to vanish. Your apps. Your data. Your Apple Wallet cards. Your eSIM.
A Note on eSIMs
This is a big one for anyone using an iPhone 14 or newer in the US. You don't have a physical SIM card anymore. When you go to wipe the phone, iOS will ask if you want to keep or delete your cellular plan. If you’re just fixing a bug and plan to keep the phone, keep the eSIM. If you’re selling it, delete it. If you delete it by accident and you still need the phone, you’ll be making a very annoying call to Verizon or AT&T to get a new QR code.
Why the "Nuclear Option" is Sometimes Necessary
Software rot is real. Over years of updates—moving from iOS 15 to 16 to 17—tiny bits of corrupted data can accumulate. It's like dust in the gears. Your battery starts draining for no reason. The camera app takes four seconds to open.
A clean install is often the only cure.
I’ve seen iPhones that were sluggish for months suddenly feel brand new after the owner decided to reset the iphone to factory settings and start fresh. Note the "start fresh" part. If you restore from a backup immediately after resetting, you might just be putting the corrupted "dust" right back into the gears. If your phone is acting buggy, try setting it up as a "New iPhone" first. Sign into iCloud so your photos and contacts sync, but let the apps download fresh from the App Store. It’s a chore, but it works.
What if the Buttons Don't Work?
Sometimes the phone is so bricked you can't even get into the Settings menu. This is where Recovery Mode comes in. You’ll need a Mac or a PC with iTunes (or the Apple Devices app on Windows 11).
- Connect the iPhone to the computer.
- Press and quickly release Volume Up.
- Press and quickly release Volume Down.
- Press and hold the Side button until you see the "connect to computer" screen. Don't let go when you see the Apple logo—keep holding.
From the computer, you can choose "Restore." This is the deepest way to reset the iphone to factory settings. It actually downloads a fresh copy of the entire operating system from Apple’s servers and overwrites everything on the flash storage. It’s the ultimate "fix-it" for a phone that’s stuck in a boot loop.

Security and Privacy Concerns
Is your data actually gone? Back in the day, you could use recovery software to "undelete" files from hard drives. With modern iPhones, that's basically impossible for a normal person. Apple uses hardware-based encryption. When you reset the iphone to factory settings, the phone doesn't just delete the files; it destroys the encryption key.
The data is technically still there on the chips, but it’s scrambled into gibberish that would take a supercomputer lifetimes to crack. You don't need to "wipe it three times" like people used to do with old PCs. One erase is plenty.
The Checklist for Success
- Back up to iCloud or a Mac. Verify the date of the last successful backup.
- Sign out of "Find My." This is the most critical step for resale value.
- Unpair your Apple Watch. Do this via the Watch app on the iPhone.
- Deregister iMessage if you’re switching to Android. If you don't, your friends' texts will get lost in the "blue bubble" void.
- Remove the SIM card (if it has one) or manage the eSIM during the prompts.
Once you hit that final confirmation and enter your passcode, the screen will go black. You’ll see the Apple logo and a progress bar. It might take two minutes; it might take ten. When it says "Hello" in fifteen different languages, you’re done.
The device is now a blank slate.
If you’re selling the phone, just turn it off at the "Hello" screen. Let the buyer go through the setup process themselves. It’s a better user experience for them and proves the phone isn't Activation Locked. If you're keeping it, go ahead and follow the prompts to bring your data back or enjoy the speed of a totally clean device.

Actionable Steps for a Clean Reset
If you're ready to proceed, follow this specific order to ensure nothing goes wrong:
- Manual iCloud Backup: Go to Settings > [Your Name] > iCloud > iCloud Backup > Back Up Now. Wait for it to finish.
- Sign Out of the Store: Go to Settings > [Your Name] and tap Sign Out at the bottom. You’ll need your Apple ID password.
- The Wipe: Settings > General > Transfer or Reset iPhone > Erase All Content and Settings.
- Verification: After the reset, wait for the "Hello" screen. To be 100% sure for a sale, try to go through the first two steps of setup. If it asks for WiFi and then moves to a "Data & Privacy" screen without asking for a previous owner's email, you have successfully cleared the Activation Lock.
