How To Restore Your iPhone To Factory Settings | Reset It Right

If your iPhone is acting up, heading to a new owner, or locked behind a passcode you can’t remember, a factory reset is the cleanest fix. It clears personal data, removes old settings, and gives you a fresh starting point. Done the right way, it also saves you from a nasty surprise later, like missing photos, a stuck Activation Lock screen, or an eSIM that vanishes when you didn’t mean to remove it.

This is one of those jobs that feels bigger than it is. The steps are simple. The prep work is what matters. Back up what you want to keep, sign out where needed, and choose the reset method that fits your situation. Once you do that, the rest is smooth.

What A Factory Reset Actually Does

A factory reset erases the content and settings stored on the iPhone itself. That includes your apps, photos, downloaded files, saved Wi-Fi networks, Face ID or Touch ID data, Apple Pay cards, messages, and custom settings. Apple says the erase process removes your information from the device and returns it to its original setup state, ready for a new setup or a new owner.

What it does not do is remove data already stored elsewhere. If your photos, contacts, notes, or files are synced to iCloud, those items can return when you sign in again and restore from backup. That’s good news if you’re resetting your own phone. If you’re selling it, you’ll want to make sure the device is fully erased and no longer tied to your account.

When This Reset Makes Sense

A full erase is worth doing when:

• You’re selling, trading in, or giving away the iPhone.
• The phone keeps crashing, freezing, or looping after regular fixes failed.
• You want a clean setup after years of clutter and old settings.
• You forgot the passcode and need to erase the device to regain access.
• You’re moving to a different iPhone and want the old one wiped clean.

Restoring Your iPhone To Factory Settings Before You Start

This is the part many people rush through. Don’t. Five extra minutes here can save hours of regret later.

Back Up The Data You Still Want

If the iPhone still works and you can unlock it, make a backup first. You can use iCloud or a computer. Apple’s restore from backup instructions are worth checking if you plan to put your data back on the same phone or move it to a new one. A backup is your safety net. Skip it, and anything stored only on the device is gone for good.

Charge The Phone And Check Your Connection

A low battery is a bad partner for an erase. Try to start with at least 50% charge, or keep the phone plugged in. If you’re using iCloud or restoring later, a steady Wi-Fi connection helps. If you’re using a computer, update macOS, Finder, Apple Devices, or iTunes first so the restore process doesn’t hit a wall halfway through.

Know Your Apple Account Password

If Find My is on, Apple may ask for your Apple Account password before the erase finishes. That step removes Activation Lock from your own setup. If you don’t know the password, stop and sort that out first. A wiped iPhone that still has Activation Lock tied to your account can be a headache for you or the next owner. Apple’s Activation Lock page shows what that screen means and how removal works.

Decide What To Do With Your eSIM

Many newer iPhones let you keep or erase the eSIM during the reset. If you’re keeping the phone, keeping the eSIM can save time during setup. If the phone is changing hands, removing it is usually the cleaner move. Read the on-screen prompt carefully instead of tapping through on autopilot.

Before You Erase	Why It Matters	What To Check
Back up your data	Prevents permanent loss of photos, messages, app data, and files	Last backup date, backup size, enough iCloud or computer storage
Charge the iPhone	Stops the reset from being interrupted by a dead battery	Battery above 50% or phone connected to power
Confirm Apple Account password	Needed to turn off Find My and clear account ties	You can sign in successfully before erasing
Check Find My status	Prevents Activation Lock trouble after the reset	Device is ready to leave your account if it’s being sold
Review eSIM choice	Affects whether your cellular plan stays on the device	Keep eSIM for your own use or remove it for a sale
Unpair Apple Watch	Clears the watch from the phone and creates a fresh watch backup	Watch shows as unpaired before you wipe the iPhone
Turn off stolen device ties	Reduces setup snags with passcodes and account locks	No old account prompts remain on the next setup
Update your computer tools	Helps a computer restore run without errors	Finder, Apple Devices, or iTunes is current

How To Restore Your iPhone To Factory Settings In Settings

This is the easiest route when the iPhone works and you can unlock it. Apple’s erase iPhone steps put everything in one place.

1. Open Settings.
2. Tap General.
3. Tap Transfer or Reset iPhone.
4. Tap Erase All Content and Settings.
5. Review the summary screen so you know what will be removed.
6. Enter your passcode if asked.
7. Enter your Apple Account password if asked.
8. Choose what to do with your eSIM, if that option appears.
9. Tap to confirm and let the iPhone finish the erase.

Once the reset starts, leave the phone alone. It may restart more than once. When it’s done, you’ll see the Hello screen. That’s your sign the device is back to factory state.

If You’re Selling Or Giving It Away

Stop at the Hello screen. Don’t set it up again. A buyer or family member should start from that screen with their own account. If you set it up again before handing it over, you just put your data flow right back into the phone you meant to clear.

How To Reset With A Computer When The iPhone Is Locked

If you forgot the passcode, the screen says iPhone Unavailable, or the phone won’t boot properly, use a computer restore. Apple says a factory restore through a computer erases the device and installs the latest iOS version available for that model.

What You Need

• A Mac with Finder, or a Windows PC with Apple Devices or iTunes
• A USB or USB-C cable
• Enough time for the software download and restore

Basic Computer Restore Flow

Turn off the iPhone, connect it to the computer, and put it into recovery mode with the button sequence that matches your model. Then select the device on the computer and choose Restore. The computer downloads the software, erases the phone, and reinstalls iOS. After that, the iPhone restarts to the Hello screen.

If the download takes a while and the iPhone exits recovery mode, repeat the recovery-mode step and try again. If the restore fails, check the cable, USB port, computer software version, and available storage, then retry.

Reset Method	Best For	Main Catch
Settings erase on the iPhone	Phones you can unlock and use normally	You need the passcode and may need the Apple Account password
Computer restore in recovery mode	Forgotten passcode, disabled iPhone, failed startup	Needs a Mac or PC, cable, and software download time
Erase then restore from backup	Keeping the phone but wanting a clean reinstall	Your old data only returns if the backup is current

What Happens After The Reset

After the iPhone reaches the Hello screen, you’ve got two paths. Set it up as new, or restore from a backup. Setting it up as new is the cleanest way to leave behind old clutter and odd settings. Restoring from backup gets your apps, data, and layout back faster.

If you’re keeping the phone, choose the path that fits why you reset it in the first place. If the goal was to clear out bugs, try a fresh setup first. If the goal was only to wipe the phone before a handoff, stop at Hello and box it up.

What Stays Gone

Anything that lived only on the phone and never made it into iCloud or a computer backup is gone after the reset. That can include local photos, voice memos, downloaded documents, app files, and text history from apps that don’t sync their own data.

Mistakes That Trip People Up

A factory reset is simple. A careless factory reset is not. These are the slipups that cause the most grief:

• Skipping the backup: once the wipe is done, there’s no easy rewind button.
• Forgetting the Apple Account password: you may get stuck at the account step right when you want the phone cleared.
• Leaving Activation Lock in place for a buyer: the phone becomes useless to the next person until the old account tie is removed.
• Erasing the eSIM by accident: that can slow down your return to service.
• Setting up the phone again before selling it: that defeats the whole point of wiping it.

Choosing The Right Reset Path

If the phone is in your hand, unlocked, and working, use Settings. It’s faster and cleaner. If it’s disabled, locked, or stuck in a bad software state, use a computer restore. If you’re trying to fix bugs, start fresh instead of dragging every old setting back in from a backup on day one.

That’s the whole play: back up what matters, erase the device with the method that fits your situation, and stop at the Hello screen if the iPhone is leaving your hands. Done that way, the reset feels less like a gamble and more like routine maintenance.
