How to Completely Reset an iPhone: A Full Guide to Every Option
Resetting an iPhone sounds straightforward — but Apple actually offers several distinct reset types, and choosing the wrong one can mean losing data you didn't intend to erase, or not fully clearing the device when you needed to. Understanding what each option does, and what factors shape the right choice, makes all the difference.
What "Resetting" an iPhone Actually Means
The word "reset" covers a wide range of actions on iOS. At one end, you have a soft reset — simply restarting the device — which clears temporary memory and resolves minor glitches without touching any data. At the other end, you have a factory reset (also called an Erase All Content and Settings), which wipes the device back to the state it left the factory.
Between those two extremes sit several intermediate options: resetting only network settings, only keyboard dictionary, only Home Screen layout, or only location and privacy settings. Each targets a specific layer of the system without affecting everything else.
Knowing which type you actually need — not just which one sounds most thorough — is the first decision to make.
The Main Reset Options on iPhone
Apple consolidates most of these options under Settings → General → Transfer or Reset iPhone → Reset.
| Reset Type | What It Clears | Data Lost? |
|---|---|---|
| Soft Reset (restart) | Temporary memory, frozen processes | No |
| Reset Network Settings | Wi-Fi passwords, VPN configs, cellular settings | Network data only |
| Reset Keyboard Dictionary | Custom learned words | No personal data |
| Reset Home Screen Layout | App icon arrangement | No |
| Reset Location & Privacy | App permissions | No |
| Erase All Content and Settings | Everything — apps, data, accounts, settings | Yes — full wipe |
The Erase All Content and Settings option is what most people mean when they say "completely reset." It removes all personal data, signs the device out of Apple ID and iCloud, and restores iOS to its default state.
How to Perform a Complete Factory Reset
Before You Start: Back Up First 🔁
A factory reset is irreversible. Once initiated, there's no retrieving data from the device itself. Before wiping, you have two backup routes:
- iCloud Backup — Go to Settings → [your name] → iCloud → iCloud Backup → Back Up Now. Requires sufficient iCloud storage.
- Mac or PC Backup — Connect via cable, open Finder (macOS Catalina and later) or iTunes (Windows/older macOS), and choose "Back Up Now."
Which backup method works best depends on your iCloud storage tier, your available computer, and how much data you have.
Performing the Reset On-Device
- Open Settings
- Tap General
- Scroll to Transfer or Reset iPhone
- Tap Erase All Content and Settings
- Enter your passcode and/or Apple ID password when prompted
- Confirm — the process begins automatically
On newer iPhones, this process is significantly faster than on older models because Apple Silicon handles secure erasure more efficiently. Older devices with more storage may take noticeably longer.
Resetting When You Can't Access the Device 📱
If the iPhone is disabled, the passcode is forgotten, or the screen is unresponsive, an on-device reset isn't possible. In those cases, the options are:
- Recovery Mode reset via Mac/PC — Hold the appropriate button combination to enter Recovery Mode, connect to a computer, and restore through Finder or iTunes. The exact button sequence varies by model (Face ID iPhones use Volume Up → Volume Down → hold Side Button; older Touch ID iPhones differ).
- iCloud's "Find My" erase — If Find My was enabled, you can remotely erase the device through iCloud.com or the Find My app from another device.
Both methods result in a full wipe. Recovery Mode may also update iOS to the latest version as part of the restore process.
Factors That Affect the Reset Process
Several variables determine exactly how a reset plays out for any given user:
iOS version — The interface and available options have shifted across iOS versions. Steps described for iOS 17 or 18 may differ slightly from earlier builds.
Device model — Activation Lock behavior, button combinations for Recovery Mode, and erase speeds all vary by hardware generation.
iCloud account status — If Activation Lock is tied to an Apple ID, the device will require that Apple ID's credentials after a reset before it can be reactivated. This is a security feature, but it's a critical factor if you're resetting a device you received from someone else.
Storage amount — More stored data generally means a longer erase process, especially on older hardware.
Repair or resale intent — If you're wiping a phone before selling or giving it away, you need to sign out of iCloud before the reset (or ensure the Apple ID is removed during the erase process) so the next user isn't blocked by Activation Lock.
The Difference Between a Reset and a Restore
These terms are often used interchangeably, but they're not the same. A reset wipes the device. A restore wipes the device and reinstalls iOS, typically via Recovery Mode or DFU Mode through a computer.
DFU (Device Firmware Update) Mode is the deepest restoration state — it reinstalls both the firmware and the operating system without loading the current iOS bootloader first. It's used for serious software issues, failed updates, or when a standard reset hasn't resolved a persistent problem.
Most users performing a routine wipe — before selling a phone, resolving persistent software issues, or starting fresh — won't need DFU Mode. But for stubborn system-level problems, it's a more thorough intervention than a standard on-device erase.
What Determines the Right Approach for Your Situation
The "complete reset" that makes sense varies considerably depending on why you're resetting and what condition the device is in. Selling a phone to a stranger, troubleshooting a sluggish device you're keeping, wiping a phone you locked yourself out of, and handing down a device to a family member — each scenario calls for a slightly different process, with different considerations around backups, Apple ID, and how deep the wipe needs to go. ⚙️
