1. What Is a Factory Reset?
A factory reset (also known as “erasing all content and settings”) is a complete wipe of your iPhone. It erases everything—your apps, contacts, photos, saved passwords, Wi-Fi settings, and personal data. The phone is restored to its original system state, just like it was the day you unboxed it.
This is different from simply restarting or powering off your phone. A restart only reboots the system, while a factory reset wipes it entirely.
2. When Should You Factory Reset Your iPhone?
There are many valid reasons to reset your iPhone:
- Selling or giving it away
- Troubleshooting persistent software glitches
- Wiping data after theft recovery
- Clearing personal info before trading in the device
- Fixing performance issues or crashes
It’s a last-resort solution in many cases, but sometimes it’s the most effective one.
3. What Happens When You Factory Reset an iPhone?
Here’s what you should expect:
- All personal content and settings are removed
- All apps and downloaded media are erased
- Your Apple ID remains linked unless you remove it
- The iPhone returns to the setup screen, just like a brand-new device
- Any iCloud, Face ID, passcode, and Bluetooth pairings are deleted
Important: If you don’t remove your Apple ID (or disable Find My iPhone), the device will stay locked due to Apple’s Activation Lock feature. This helps prevent stolen devices from being reused.
4. Things to Do Before Resetting Your iPhone
Before you proceed, there are a few important steps to take:
✅ 1. Back Up Your Data
You may want to save your photos, messages, and other content.
✅ 2. Sign Out of iCloud and Apple ID
To avoid Activation Lock issues, go to:
Settings > [Your Name] > Sign Out
✅ 3. Disable “Find My iPhone”
This also helps with resale or trade-in:
Settings > [Your Name] > Find My > Find My iPhone > Turn Off
You may be asked to enter your Apple ID password.
✅ 4. Charge Your Device
Make sure your iPhone is at least 50% charged, or keep it plugged in.
5. How to Backup Your iPhone (Optional but Recommended)
You have two easy options:
Method 1: Using iCloud
- Go to Settings > [Your Name] > iCloud > iCloud Backup
- Tap Back Up Now
- Wait until the backup is completed (stay connected to Wi-Fi)
Method 2: Using a Computer
- Connect your iPhone to a PC or Mac
- On macOS Catalina or later, open Finder
- On macOS Mojave or Windows, open iTunes
- Select your device > Click Back Up Now
This step is optional, but crucial if you don’t want to lose your data.
6. How to Factory Reset an iPhone from Settings
This is the most straightforward way to reset an iPhone.
Steps:
- Open the Settings app
- Go to General
- Scroll down and tap Transfer or Reset iPhone
- Tap Erase All Content and Settings
- You may be prompted to enter your passcode or Apple ID password
- Confirm your choice and wait for the process to complete
Your phone will restart and show the Apple logo with a progress bar. Once finished, it’ll display the “Hello” screen like a brand-new device.
7. How to Factory Reset an iPhone Using a Computer
This method is helpful if your phone isn’t responding or if you’ve forgotten the passcode.
Steps:
- Connect your iPhone to a computer using a Lightning cable
- Open Finder (Mac) or iTunes (Windows)
- Put your iPhone into Recovery Mode:
- For iPhone 8 or later: Press and quickly release the Volume Up, then the Volume Down, then press and hold the Side button until the recovery screen appears.
- For iPhone 7/7 Plus: Press and hold the Volume Down and Side buttons at the same time.
- For iPhone 6s and earlier: Press and hold the Home and Top/Side buttons together.
- Your computer will show a message: Restore or Update
- Click Restore
- The computer will download software and reset your iPhone
Once the process completes, your iPhone will be reset to factory settings.
8. How to Factory Reset an iPhone Without a Password
If you’ve forgotten your passcode or Apple ID password, a reset is still possible—but with extra steps.
Option: Use Recovery Mode (as shown above)
This will erase the iPhone completely, including the passcode. However, if Find My iPhone is still on, you’ll need the Apple ID to reactivate the phone after the reset.
Note on Security:
Apple has strict security measures in place. If you don’t know your Apple ID or can’t recover it, you won’t be able to use the device after a reset due to Activation Lock.
9. After the Reset: Setting Up Your iPhone Again
After the factory reset, your iPhone will start up as if it’s brand new.
Setup Options:
- Set up as new iPhone: Ideal if you’re giving it away or starting fresh
- Restore from iCloud Backup: Great if you backed up before resetting
- Restore from Mac or PC: Use this if you backed up using iTunes or Finder
Just follow the on-screen prompts to choose your language, Wi-Fi, and sign in to your Apple ID.
10. Final Thoughts and Best Practices
Performing a factory reset on an iPhone doesn’t have to be intimidating. When done correctly, it’s a secure and effective way to refresh your device, clear up problems, or prepare it for a new owner.
Best Practices:
