The Apple Watch is one of the most powerful and personalized smart devices you can own. It tracks your workouts, handles notifications, helps you navigate, and even allows you to make calls—all synced seamlessly with your iPhone. But what happens when you need to unpair your Apple Watch from your iPhone?
Whether you’re switching to a new iPhone, selling or gifting your Apple Watch, troubleshooting an issue, or simply starting fresh, unpairing is a critical step—and it should be done the right way to prevent data loss and connectivity issues.
In this detailed guide, we’ll show you how to safely unpair your Apple Watch from your iPhone, step-by-step, while preserving your important data. We’ll also explore what happens after unpairing, how to re-pair your devices later, and answer common questions around backups, iCloud, and Activation Lock.
Let’s dive in.
1. Why Would You Need to Unpair an Apple Watch?
Here are the most common reasons people unpair their Apple Watch from their iPhone:
- Upgrading to a new iPhone
- Selling, trading, or gifting the watch
- Resetting to factory settings
- Fixing syncing or performance issues
- Switching to a different Apple ID
- Pairing with a new iPhone or user
No matter the reason, it’s important to follow the correct steps so your data is backed up, Activation Lock is removed, and the watch can be paired again smoothly.
2. What Happens When You Unpair an Apple Watch?
Unpairing your Apple Watch from your iPhone does a few important things:
- Creates a backup of your Apple Watch data on your iPhone
- Disconnects Bluetooth and Wi-Fi pairing
- Erases all content and settings from the Apple Watch
- Removes Activation Lock (if done through the Watch app)
- Allows the watch to be paired again with the same or a different iPhone
That means your health data, custom watch faces, app settings, and more can be restored when you re-pair the watch later—as long as you unpair correctly.
3. Before You Begin: What You Need
To successfully unpair your Apple Watch, make sure:
- Your iPhone and Apple Watch are close together
- Both devices are charged
- You know your Apple ID password (for removing Activation Lock)
- You’re using the Apple Watch app on the iPhone currently paired with the watch
4. Method 1: Unpair Apple Watch Using the Watch App (Recommended)
This is the safest and most complete method. It ensures your data is backed up and Activation Lock is properly removed.
✅ Step-by-Step Instructions:
- On your iPhone, open the Watch app.
- Tap the My Watch tab at the bottom of the screen.
- Select your Apple Watch at the top of the screen.
- Tap the info icon (ℹ️) next to your watch’s name.
- Tap Unpair Apple Watch.
⏱ A few additional steps will follow:
- If your Apple Watch is cellular, you’ll be asked whether you want to keep or remove your cellular plan.
- Select Keep Plan if you plan to pair the watch with another iPhone soon.
- Select Remove Plan if you’re giving the watch away.
- Enter your Apple ID password to disable Activation Lock.
- The watch will begin erasing all content and settings.
Once done, the Apple Watch will restart and show the welcome screen, ready to pair with a new iPhone.
✔ Pros:
- Safest way to unpair
- Triggers automatic backup
- Removes Activation Lock
- Retains your watch settings in iCloud for future use
✖ Cons:
- Requires Apple ID and internet access
5. Method 2: Unpair Directly from the Apple Watch (Without iPhone)
If you no longer have the iPhone paired with the watch, or the iPhone is broken, you can unpair directly from the watch. But beware—this does not remove Activation Lock, which can cause issues when giving the watch to someone else.
✅ Steps:
- On your Apple Watch, go to Settings > General > Reset.
- Tap Erase All Content and Settings.
- Enter your passcode if prompted.
- Confirm by tapping Erase All.
This will wipe the watch and return it to factory settings, but Activation Lock will remain unless you later remove it through iCloud (see Method 3).
✔ Pros:
- Useful when iPhone is lost or inaccessible
- Fast and device-only method
✖ Cons:
- Activation Lock will stay enabled
- May require iCloud access later to fully unpair
6. Method 3: Remove Apple Watch from iCloud (Activation Lock Only)
If you’ve already erased your watch but forgot to unpair properly, you can still remove Activation Lock through iCloud.
✅ Steps:
- Go to Settings > [Your Name] > iCloud on your iPhone.
- Tap Find My > Find My iPhone > All Devices.
- Select your Apple Watch from the list.
- Tap Remove from Account.
Once removed, the watch is completely unlinked from your Apple ID and can be set up by someone else.
7. How to Back Up Apple Watch Data Before Unpairing
The good news is that you don’t need to back up your Apple Watch manually. When you unpair it using the Watch app, a backup is created automatically on your iPhone.
This backup includes:
- App data
- Watch face layouts
- Health and fitness data
- Settings (like dock and notification preferences)
- Music, playlists, and synced photos (if applicable)
When you re-pair your Apple Watch, you’ll be prompted to restore from this backup.
📦 Want to make sure your iPhone itself is backed up?
- Go to Settings > [Your Name] > iCloud > iCloud Backup, and tap Back Up Now.
8. What If You’re Switching to a New iPhone?
Before pairing your Apple Watch with your new iPhone, follow these steps:
📲 Recommended Steps:
- On your old iPhone, unpair the Apple Watch using the Watch app.
- Backup your old iPhone to iCloud or to a computer.
- Set up your new iPhone and restore from backup.
- Open the Watch app on the new iPhone and re-pair your watch.
- When prompted, choose to Restore from Backup.
This method ensures your Apple Watch gets all its data and settings from the old iPhone.
9. Can You Unpair Without Losing Data?
Yes—if you unpair using the Watch app, your data is backed up to your iPhone automatically.
However:
- If you erase the watch directly (from the watch or iCloud), some data may be lost unless previously backed up.
- Health data is backed up only if you have iCloud enabled for Health or use encrypted iTunes backups.
10. Common Problems and Fixes

Unpairing your Apple Watch might seem like a small step, but doing it correctly ensures a smooth transition, whether you’re switching devices, solving a bug, or passing the watch to someone else.
