How to Completely Reset an iPhone: A Full Guide to Every Option
Resetting an iPhone sounds simple until you realize there are actually several different types of resets — and choosing the wrong one can mean losing everything or, worse, not solving the problem you were trying to fix. Here's exactly how each reset works, what it does to your data, and what determines which approach makes sense for your situation.
What "Completely Reset" Actually Means
When most people say they want to completely reset their iPhone, they usually mean one of two things: wiping it back to factory settings (like it just came out of the box) or resetting specific settings without touching their data. These are very different operations.
Apple uses the term Erase All Content and Settings for a true factory reset. This removes:
- All apps, photos, videos, and files
- All accounts (Apple ID, email, social media)
- All saved passwords and payment info
- All personalized settings (Wi-Fi, Bluetooth, display preferences)
What you get back is a blank iPhone running its current version of iOS — exactly like a new device.
Before You Do Anything: Back Up First 🔒
A complete reset is irreversible. Once it's done, there's no undo button. Before wiping anything, make sure your data is safe.
Two main backup options:
| Method | Where Data Goes | What It Backs Up |
|---|---|---|
| iCloud Backup | Apple's cloud servers | Photos, apps, settings, messages |
| iTunes/Finder Backup | Your Mac or PC | Same as above, locally stored |
To back up via iCloud: Settings → [Your Name] → iCloud → iCloud Backup → Back Up Now
To back up via a computer: Connect your iPhone, open Finder (Mac) or iTunes (Windows), select your device, and click Back Up Now.
iCloud backups require enough available iCloud storage — free accounts include 5GB, which fills up fast on most active phones. Computer backups have no storage ceiling beyond your hard drive space.
How to Perform a Complete Factory Reset
Once you're backed up, the process is straightforward on modern iPhones running iOS 15 or later.
Via Settings (the standard method):
- Open Settings
- Tap General
- Scroll down and tap Transfer or Reset iPhone
- Tap Erase All Content and Settings
- Enter your passcode if prompted
- Confirm — the process takes a few minutes
The phone will restart, display the Apple logo, and present the setup screen as if it's brand new.
If you've forgotten your passcode:
You'll need to use Recovery Mode via a computer. Connect the iPhone to a Mac or PC, force-restart into recovery mode (the button combination varies by iPhone model), then use Finder or iTunes to restore the device. This approach erases everything without needing the passcode — but it also means no pre-reset backup unless you'd already made one.
If the iPhone is disabled or locked out:
Apple also offers remote erase through iCloud.com → Find My → select your device → Erase iPhone. This requires the iPhone to be signed into an Apple ID and have an internet connection (or connect to one in the future to complete the wipe).
Partial Resets: When You Don't Need to Erase Everything
A full wipe isn't always the right move. Apple offers several targeted reset options under Settings → General → Transfer or Reset iPhone → Reset that leave your data intact:
- Reset All Settings — Restores every setting (Wi-Fi passwords, display preferences, notification settings, privacy permissions) to default without deleting any files or apps. Useful for fixing glitchy behavior.
- Reset Network Settings — Clears all Wi-Fi networks, Bluetooth pairings, and VPN configurations. Helpful for persistent connectivity issues.
- Reset Keyboard Dictionary — Removes custom words your keyboard learned over time.
- Reset Home Screen Layout — Returns app icons to their default arrangement.
- Reset Location & Privacy — Resets all app permissions for location, camera, microphone, etc.
These options solve a surprising number of common iPhone problems without the commitment of a full erase.
Factors That Affect How Your Reset Goes
Not every reset experience is identical. A few variables meaningfully change what happens:
iOS version — The path through Settings has shifted across iOS versions. On older iOS (pre-15), the reset option lived under Settings → General → Reset without the "Transfer or Reset" intermediate step.
Whether Find My iPhone is enabled — If it is, you'll need to sign out of your Apple ID or enter your Apple ID password during the erase process. This is Activation Lock — Apple's anti-theft layer. A device with Activation Lock that's been wiped without signing out first will prompt for the original Apple ID credentials on setup, making it unusable without them.
Device age and iOS support — Very old iPhones (iPhone 6 and earlier) have limited iOS support, which affects what backup features are available and how recovery mode works.
Storage amount — More data means a longer backup time and a slightly longer erase process, though the wipe itself is fast regardless.
Reason for the reset — Selling or giving away the phone requires a full erase plus signing out of Apple ID. Troubleshooting a software bug might only need a settings reset or network reset. Preparing for a major iOS update sometimes benefits from a clean install rather than an upgrade.
What Happens to Your Apple ID After a Reset
Erasing an iPhone does not delete your Apple ID or any data stored in iCloud. Your purchased apps, iCloud Photos, contacts, and other cloud data remain tied to your account. Signing back in after setup (or on a new device) pulls all of it back down.
However, if you're passing the phone to someone else, it's essential to go to Settings → [Your Name] → Sign Outbefore erasing, or remove the device from your Apple ID at appleid.apple.com. Skipping this step leaves Activation Lock in place and makes the phone very difficult for the next owner to use.
The Variables That Make This Personal
The mechanics of resetting an iPhone are consistent — but whether a full erase, a partial reset, or a recovery-mode wipe is the right call depends on what's actually happening with your specific device. A phone that's behaving strangely might recover completely with just a network or settings reset. A phone being sold needs a full erase with a clean sign-out. A locked or disabled device requires a different path entirely.
Your reason for resetting, your current iOS version, your backup status, and whether Activation Lock is involved all shape which steps apply to your situation — and which ones you can safely skip. 📱
