Tutorial – How to Unpair Apple Watch from iPhone 16

The main method below removes the Apple Watch from your iPhone 16 cleanly and also creates a backup of your watch data if the watch is still connected. That makes it the best option for selling, trading in, or pairing the watch with a new iPhone later.

Step 1: Open the Watch app on your iPhone 16

Launch the Watch app from your iPhone 16 Home Screen or App Library.

Once the app opens, you should see the main Watch interface with your paired watch listed. If you are signed into multiple Apple devices, make sure you are using the correct iPhone before continuing.

Step 2: Go to your watch list

Tap All Watches at the top of the screen if you do not already see your paired watch.

You will usually see the name of your Apple Watch here, along with a small info icon next to it. This is the screen where Apple manages all pairing and unpairing actions.

Step 3: Tap the info button next to your Apple Watch

Select the small i or info button beside the watch you want to remove.

This opens the details page for that specific watch. It is important to pick the right watch if you have more than one paired, since the unpairing process removes the chosen device from your iPhone.

Step 4: Tap Unpair Apple Watch

Scroll down and tap Unpair Apple Watch.

At this point, your iPhone may ask whether you want to keep or remove your cellular plan if your watch has cellular service. If you plan to pair the watch again with another iPhone, follow the on-screen choice that matches your goal. If you are selling it, you usually want to remove the plan.

Step 5: Confirm the unpairing and enter your Apple ID password if prompted

Tap Unpair [Apple Watch name] again to confirm, then enter your Apple ID password if prompted.

This step turns off Activation Lock, Apple’s theft-protection feature. After you authenticate, your iPhone will start the unpairing and backup process. You may see a progress message on the screen while the watch is erased.

Step 6: Wait for the Apple Watch to finish unpairing

Let the process complete. Your Apple Watch will erase itself and restart to the setup screen when it is done.

When it finishes, the watch is no longer paired to your iPhone 16. If you want to use it again, you can set it up as a new watch or restore it from backup during pairing.

Alternative Methods or Edge Cases

Unpair directly from the Apple Watch if you do not have the iPhone 16

If you no longer have access to the paired iPhone, you can erase the watch from the device itself.

• On the Apple Watch, open Settings
• Tap General
• Tap Transfer or Reset Apple Watch
• Tap Erase All Content and Settings

This removes the data from the watch, but Activation Lock may still remain unless you also remove the watch from your Apple ID in Find My or iCloud.

Remove the watch from your Apple ID using Find My

If the watch was lost, sold, or reset already, remove it from your account remotely.

• Open the Find My app on another Apple device or go to iCloud on the web
• Select your Apple Watch
• Choose Remove This Device

This helps disable Activation Lock and clears the watch from your Apple account.

Temporarily stop Apple Watch notifications instead of unpairing

If your goal is just less noise, do not unpair it yet.

• Open the Watch app
• Tap Notifications
• Turn off alerts for specific apps

This keeps the watch paired, but cuts down on interruptions.

Pair the watch with a new iPhone instead of fully removing it

If you are upgrading to another iPhone, you may not need to do anything dramatic.

• Back up your iPhone first
• Unpair the watch from the old iPhone if possible
• Set up the new iPhone
• Pair the watch again during setup

This is usually the smoothest path if you want to keep your watch data and health history.

Frequently Asked Questions

Will unpairing my Apple Watch delete everything?

Yes, the watch is erased during unpairing. If you unpair from the iPhone app, Apple usually creates a backup first, which can be restored later when you pair it again.

Do I need my Apple ID password to unpair?

Often, yes. If Activation Lock is enabled, your Apple ID password is required to complete the process and fully disconnect the watch from your account.

Can I unpair the watch if my iPhone 16 is broken or missing?

Yes, but you may need to erase the watch directly and then remove it from Find My or your Apple ID account online.

What happens to my cellular plan when I unpair?

If your Apple Watch uses cellular, you may be asked whether to keep or remove the plan. Removing the plan is usually the right choice if you are selling or giving away the watch.

How do I pair the watch again later?

After unpairing, turn on the Apple Watch, bring it near your iPhone 16, and follow the on-screen pairing prompts in the Watch app.

Can I unpair without losing health data?

If you unpair through the iPhone’s Watch app, Apple preserves a backup in most cases. That backup can restore your watch settings and health data when you pair again.

Tips

• Make sure your iPhone 16 has enough battery before starting. A dead phone can interrupt the unpairing process.
• Keep your Apple ID password handy. You may need it to disable Activation Lock.
• If you are selling the watch, remove the cellular plan and sign out of Apple services first.
• Back up your iPhone before pairing to a new device. That makes restoring your watch and health data much easier.
• If the watch belongs to a family member, confirm whose Apple ID is linked to it before you unpair.

Troubleshooting

• If Unpair Apple Watch is greyed out, restart both devices and try again. A temporary software glitch can block the option.
• If the watch will not unpair, turn Bluetooth and Wi-Fi on your iPhone 16, then try again. The watch often needs a stable connection to complete the process.
• If you forgot your Apple ID password, reset it at iforgot.apple.com before trying to unpair. Without it, Activation Lock may stop the process.
• If the watch seems stuck during erasing, place it on its charger and wait a few minutes. Low battery can slow down or interrupt the reset.
• If the watch still appears in Find My after unpairing, remove it manually from your Apple ID devices list. This clears the leftover account link.

Conclusion

Unpairing an Apple Watch from an iPhone 16 is usually straightforward, and the built-in Watch app makes it a fast process. In most cases, it only takes a few taps, plus your Apple ID password if Activation Lock is enabled.

If you are switching phones, selling the watch, or simply cleaning up your device list, following the steps above will disconnect the watch safely and cleanly. Once it is unpaired, you can set it up again later or pass it on with confidence.
