If your iPhone is acting up, lagging, or you plan to sell or give it away, doing a factory reset is the best move. Performing a factory reset on your iPhone erases all data and returns the device to its original state—just like it came out of the box.
This guide walks you through the entire process and highlights what to do before and after the reset to keep your data and privacy secure.
Let’s get started.
What Is a Factory Reset?
A factory reset completely erases your iPhone, removing all your apps, settings, media, and personal data. After the reset, the phone will reboot with the default iOS setup screen.
Unlike a soft reset or force restart, a factory reset wipes everything permanently. Therefore, it’s critical to back up your data first.
According to Wikipedia, this process is commonly used to fix software problems, clear malware, or prepare a device for resale.
When Should You Factory Reset Your iPhone?
Not sure if a full reset is necessary? Here are common situations where it makes sense:
| Scenario | Reason for Reset |
|---|---|
| iPhone is freezing or crashing | To eliminate corrupted system files |
| Selling or giving away your phone | To remove all personal data |
| iOS bugs that won’t go away | To reinstall a clean iOS version |
| Starting fresh after years of use | To remove clutter and outdated apps |
For smaller issues like short battery life, you might not need a full reset. Instead, check out our guide on How to Improve iPhone Battery Life.
How to Back Up Before Resetting
Before resetting, always back up your iPhone to avoid losing important information. You can use iCloud or your computer.
iCloud Backup
- Connect your iPhone to Wi-Fi
- Go to Settings > Your Name > iCloud
- Tap iCloud Backup
- Select Back Up Now
Backup Using a Computer
| Platform | Steps |
|---|---|
| Mac (macOS Catalina or later) | Use Finder > Select your iPhone > Back Up Now |
| Windows or older macOS | Open iTunes > Select your iPhone > Back Up Now |
Backing up is essential because once the reset is complete, everything on the phone is wiped out.
How to Factory Reset Your iPhone
After backing up your data, follow these steps to reset your iPhone:
- Open Settings
- Tap General
- Scroll down and select Transfer or Reset iPhone
- Tap Erase All Content and Settings
- Enter your passcode or Apple ID password
- Confirm the reset
The iPhone will restart and begin erasing all data. This process can take a few minutes depending on the size of your storage.
Tip: Make sure your device has at least 50% battery or plug it in during the reset.
What Happens After the Reset?
Once the reset is complete, your iPhone will display the initial setup screen. At this point, you can either set it up as new or restore it from your backup.
| Option | What It Does |
|---|---|
| Set Up as New | Starts with a clean slate, no previous data |
| Restore from Backup | Brings back your apps, photos, and settings |
If privacy is your concern, resetting your iPhone also removes all Apple Intelligence data. But for a deeper clean, learn how to Disable Apple Intelligence Features on iPhone.
Things to Do After Resetting
After the reset, here are a few steps to get back on track quickly:
| Step | Purpose |
|---|---|
| Reconnect to Wi-Fi | Needed for setup and restoring from iCloud |
| Log in to Apple ID | To access iCloud, App Store, and Apple services |
| Restore from backup | Optional, depending on whether you want old data back |
| Update to latest iOS | Ensures better security and features |
This is also a great time to reorganize your apps, delete unused ones, and improve device performance.
