Knowing how to restore iPhone to factory settings can solve problems that no update or restart will fix. A full reset erases everything and returns the device to its original state.
This process is essential before selling your iPhone or when facing serious software issues. It removes all personal data, accounts, and configurations permanently.
Apple provides two reliable methods to complete a factory reset: directly through the iPhone Settings app or using a computer with Finder or iTunes.

Before You Reset: What to Do First
A factory reset permanently deletes all data on your iPhone. There is no way to recover files after the process unless you have a backup.
Before proceeding, complete these steps:
- Back up your iPhone to iCloud or your computer via Finder or iTunes
- Sign out of iCloud by going to Settings, tapping your name, and selecting Sign Out
- Disable Find My iPhone under Settings, your name, then Find My
- Charge your device to at least 50% battery
- Note your Apple ID credentials, as you will need them after setup
Skipping the backup step means losing photos, messages, contacts, and app data. Apple recommends backing up to iCloud before any major reset. If your iCloud plan is limited, consider using your computer as the backup destination instead. Many users also review their icloud storage options at this stage to ensure the backup fits their current plan.
How to Reset iPhone via Settings
The simplest method requires no computer. You can complete the entire process directly from the iPhone itself.
Follow these steps in order:
- Open the Settings app on your iPhone
- Scroll down and tap General
- Scroll to the bottom and tap Transfer or Reset iPhone
- Tap Erase All Content and Settings
- Enter your passcode when prompted
- Confirm by tapping Erase iPhone
The device will restart and begin the erase process. This can take several minutes depending on the amount of data stored. Once complete, the iPhone displays the initial setup screen, just as it did when new.
If the option is grayed out or unavailable, you likely need to disable Find My iPhone first. Go to Settings, tap your Apple ID name, select Find My, then Find My iPhone, and toggle it off.
How to Restore iPhone Using a Computer
Restoring via a computer gives you more control and is useful when the iPhone is unresponsive or locked. The process differs slightly depending on your operating system.
On Mac (macOS Catalina or later):
- Connect your iPhone to the Mac using a USB cable
- Open Finder and select your iPhone in the sidebar
- Click Restore iPhone under the General tab
- Confirm the action and wait for the process to complete
On Windows or older macOS:
- Connect your iPhone and open iTunes
- Click the iPhone icon near the top left of the window
- Click Restore iPhone in the Summary panel
- Confirm and allow iTunes to download the latest iOS firmware
The computer will download the latest version of iOS and install it fresh on the device. Make sure your internet connection is stable during this step, as the firmware file can be several gigabytes.
Using Recovery Mode for a Complete Restore
Recovery Mode is necessary when your iPhone is stuck in a boot loop, disabled after too many passcode attempts, or unresponsive to normal reset methods.
To enter Recovery Mode, the button combination depends on your iPhone model:
- iPhone 8 and later: Press and release Volume Up, press and release Volume Down, then hold the Side button until the recovery screen appears
- iPhone 7 and 7 Plus: Hold Volume Down and the Sleep/Wake button simultaneously until the recovery screen appears
- iPhone 6s and earlier: Hold the Home button and the Sleep/Wake button together until the recovery screen appears
Once in Recovery Mode, Finder or iTunes will detect the device and offer two options: Update or Restore. Choose Restore to perform a full factory reset. The Update option attempts to reinstall iOS without erasing data, which is useful if you want to preserve your files.
If Recovery Mode fails or the device is not recognized, Apple Support provides additional diagnostic steps at apple.com. For devices under warranty, visiting an Apple Store or authorized service provider is a reliable alternative.
What Happens After the Factory Reset
After the reset completes, the iPhone restarts and displays the Hello screen. From this point, you have two paths: set up as a new device or restore from a backup.
If you are selling or giving away the iPhone, leave it at the Hello screen. The new owner will set it up with their own Apple ID. Do not proceed through setup on their behalf.
If you are keeping the device, follow these steps during setup:
- Select your language and region
- Connect to a Wi-Fi network
- Sign in with your Apple ID
- Choose to restore from an iCloud backup or a local backup
- Wait for apps and data to download and sync
Restoring from a backup brings back your apps, photos, messages, and settings. The process can take anywhere from a few minutes to over an hour, depending on backup size and connection speed. Keep the iPhone plugged in and connected to Wi-Fi throughout.
Frequently Asked Questions About Restoring iPhone
Will a factory reset remove my Apple ID from the iPhone?
Yes, if you sign out of iCloud before the reset. If you do not sign out first, Activation Lock remains active and the new user will need your Apple ID and password to set up the device. Always sign out before resetting a device you plan to sell or give away.
Can I restore my iPhone without a computer?
Yes. The Settings method described above requires no computer at all. You only need the iPhone, your passcode, and your Apple ID credentials. A computer is needed only for Recovery Mode or when the iPhone cannot be accessed normally.
Does a factory reset fix software bugs and slow performance?
In most cases, yes. A factory reset clears corrupted files, accumulated cache, and software conflicts that cause slowdowns or crashes. After restoring from a clean backup or setting up as new, most performance issues are resolved.
How long does a factory reset take?
The erase process itself typically takes between 5 and 20 minutes. If you are restoring from a backup afterward, the total time depends on the backup size and your internet speed. Large backups with many apps can take an hour or more to fully restore.
What happens to my iCloud data after a factory reset?
iCloud data is stored on Apple’s servers and is not deleted by a factory reset on the device. Your photos, contacts, and documents remain in iCloud until you manually delete them. When you sign back in with your Apple ID, everything syncs back to the device.
Can I cancel a factory reset once it has started?
No. Once you confirm the erase, the process cannot be stopped or reversed. This is why backing up beforehand is critical. If the device loses power mid-reset, it may enter Recovery Mode and require a restore via computer.
Conclusion
The process of how to restore iPhone to factory settings is straightforward when you follow the correct sequence. Back up your data, sign out of iCloud, and choose the method that fits your situation: Settings for a quick reset, Finder or iTunes for a computer-based restore, or Recovery Mode for unresponsive devices.
Taking a few minutes to prepare before the reset prevents permanent data loss and ensures a smooth experience. Whether you are troubleshooting, selling, or starting fresh, a factory reset returns your iPhone to a fully functional, clean state.
