Before we dive into the steps, let’s talk about why someone would want to disconnect their smart watch in the first place. Understanding your reason can help you choose the right method and avoid mistakes.
- Switching to a new iPhone: If you’ve upgraded your phone, you’ll need to unpair your watch from the old device before setting it up on the new one.
- Selling or giving away your watch: To protect your personal data, you should disconnect and reset the watch before handing it over.
- Troubleshooting connectivity issues: Sometimes, unpairing and reconnecting can fix bugs, sync problems, or battery drain.
- Switching to an Android phone: Most smart watches (except Apple Watch) can work with Android, but you’ll need to disconnect from iPhone first.
- Privacy concerns: If you’re concerned about data tracking or app permissions, disconnecting gives you a clean break.
- Testing a new watch: If you’re trying out a different model, you may want to disconnect your current one temporarily.
No matter your reason, the process is straightforward—but it’s important to do it correctly to avoid losing data or causing sync issues.
How to Disconnect an Apple Watch from iPhone
If you’re using an Apple Watch, the process is built right into the iPhone’s Watch app. Apple makes it easy, but there are a few key steps to follow to ensure a clean disconnect.
Step 1: Open the Watch App on Your iPhone
First, unlock your iPhone and find the Watch app. It looks like a white icon with a blue watch face. Tap to open it.
Once inside, you’ll see your watch listed at the top of the screen under “My Watch.” Make sure your Apple Watch is nearby and powered on—this ensures a smooth disconnection.
Step 2: Tap on Your Watch Name
In the Watch app, tap on the name of your Apple Watch (e.g., “John’s Apple Watch”). This will open the watch’s settings menu.
Scroll down until you see the option that says “Unpair Apple Watch”. It’s usually near the bottom of the screen, in red text.
Step 3: Confirm the Unpairing
Tap “Unpair Apple Watch.” Your iPhone will ask you to confirm. It may also warn you that unpairing will erase all data on the watch.
If you have an Apple Watch with cellular, you’ll be asked whether you want to keep or remove your cellular plan. Choose “Remove” if you’re selling the watch or switching carriers.
Tap “Unpair” again to confirm.
Step 4: Wait for the Process to Complete
Your iPhone will now begin the unpairing process. This may take a minute or two. During this time, your Apple Watch will restart and return to its setup screen.
Once complete, your watch is officially disconnected from your iPhone. You’ll see the “Hello” screen, just like when you first bought it.
Step 5: Turn Off Bluetooth (Optional but Recommended)
Even after unpairing, your iPhone might still try to reconnect to the watch if Bluetooth is on. To prevent this, go to Settings > Bluetooth on your iPhone and toggle Bluetooth off.
This is especially helpful if you’re planning to pair the watch with a different phone or don’t want accidental connections.
Bonus Tip: Back Up Your Watch Data
Before unpairing, your iPhone automatically creates a backup of your Apple Watch data—including health, fitness, and app settings—as long as you’re signed in to iCloud.
To check if your data is backed up:
- Go to Settings > [Your Name] > iCloud > iCloud Backup
- Make sure iCloud Backup is turned on
- Tap “Back Up Now” to ensure the latest data is saved
This backup will help you restore your watch quickly if you reconnect it later.
How to Disconnect a Non-Apple Smart Watch from iPhone
Not all smart watches are Apple Watches. Many people use Samsung Galaxy Watches, Fitbits, Garmin devices, or Wear OS watches (like those from Fossil or Mobvoi) with their iPhones.
The process for disconnecting these watches is a bit different, but still manageable. Here’s how to do it for the most popular brands.
Disconnecting a Samsung Galaxy Watch from iPhone
Samsung Galaxy Watches can pair with iPhones using the Galaxy Wearable app (formerly Samsung Gear). To disconnect:
Step 1: Open the Galaxy Wearable App
Launch the Galaxy Wearable app on your iPhone. Make sure your watch is nearby and connected.
Step 2: Tap on Your Watch
Tap the name of your Galaxy Watch at the top of the screen.
Step 3: Go to Settings
Tap the gear icon (settings) in the top-right corner.
Step 4: Select “Disconnect” or “Unpair”
Scroll down and look for an option like “Disconnect,” “Unpair,” or “Remove Device.” Tap it.
Confirm when prompted. The app will disconnect the watch and may ask if you want to delete data.
Step 5: Reset the Watch (Optional)
If you’re selling or giving away the watch, go to the watch itself:
- Open Settings
- Scroll to “General” > “Reset”
- Tap “Reset” and confirm
This will erase all data and return the watch to factory settings.
Disconnecting a Fitbit from iPhone
Fitbit devices use the Fitbit app to sync with iPhones. To disconnect:
Step 1: Open the Fitbit App
Launch the Fitbit app on your iPhone and make sure your device is connected.
Step 2: Tap Your Profile Icon
Tap the profile icon (usually in the top-left corner).
Step 3: Select Your Device
Tap on the name of your Fitbit watch or tracker.
Step 4: Scroll Down and Tap “Remove This [Device]”
You’ll find this option near the bottom of the screen. Tap it and confirm.
The app will disconnect the device and stop syncing data.
Step 5: Turn Off Bluetooth
Go to Settings > Bluetooth on your iPhone and toggle it off to prevent reconnection.
Bonus: Log Out of Fitbit Account (Optional)
If you’re selling the device, consider logging out of your Fitbit account in the app to protect your data.
Disconnecting a Wear OS Watch (e.g., Fossil, Mobvoi) from iPhone
Wear OS watches use the Wear OS by Google app to connect to iPhones.
Step 1: Open the Wear OS App
Launch the app and ensure your watch is connected.
Step 2: Tap on Your Watch
Tap the name of your watch at the top.
Step 3: Tap the Gear Icon (Settings)
Go to the settings menu.
Step 4: Select “Disconnect” or “Unpair”
Look for an option to disconnect or unpair the device. Tap it and confirm.
Step 5: Reset the Watch (Recommended)
On the watch:
- Open Settings
- Scroll to “System” > “Reset Options”
- Tap “Erase all data” and confirm
This ensures no personal data remains on the device.
How to Disconnect Any Smart Watch Manually (Without the App)
Sometimes, the companion app might not work—maybe it’s crashed, outdated, or you’ve deleted it. In those cases, you can still disconnect your smart watch manually using Bluetooth settings.
Step 1: Go to iPhone Settings
Open the Settings app on your iPhone.
Step 2: Tap “Bluetooth”
Scroll down and tap on Bluetooth. You’ll see a list of connected devices.
Step 3: Find Your Smart Watch
Look for your watch in the list under “My Devices.” It might be labeled as “Apple Watch,” “Galaxy Watch,” “Fitbit,” or something similar.
Step 4: Tap the “i” Icon
Next to your watch’s name, tap the small “i” (information) icon.
Step 5: Select “Forget This Device”
Tap “Forget This Device” and confirm when prompted.
This will remove the watch from your iPhone’s Bluetooth list and stop all connections.
Important Note:
While this method disconnects the watch from Bluetooth, it doesn’t always fully unpair it—especially for Apple Watches. For a complete disconnect, always use the official app when possible.
What to Do After Disconnecting Your Smart Watch
Once your smart watch is disconnected, there are a few smart next steps to take—especially if you’re selling, upgrading, or switching devices.
1. Back Up Your Data
Even if you’ve already backed up, double-check that your health, fitness, and app data are saved. For Apple Watch, this is done automatically via iCloud. For others, check the companion app’s backup settings.
2. Perform a Factory Reset (If Selling or Giving Away)
This is crucial for privacy. A factory reset erases all personal data, accounts, and settings from the watch.
- Apple Watch: Unpairing automatically resets the watch.
- Samsung, Wear OS, Fitbit: Go to the watch’s settings and find “Reset” or “Erase All Data.”
3. Remove the Watch from Your Account
Some watches stay linked to your online account even after disconnection. For example:
- Log in to your Samsung account and remove the device
- Go to Google Account > Devices and remove the Wear OS watch
- Check Fitbit.com and remove the device from your account
This prevents the next user from accessing your data.
4. Turn Off Find My (For Apple Watch)
If you have “Find My” enabled, your Apple Watch may still be linked to your Apple ID. To fully disconnect:
- Go to Settings > [Your Name] > Find My > Find My iPhone
- Turn off “Find My iPhone”
- Or, during unpairing, make sure “Find My” is disabled
This ensures the watch can be set up by a new owner.
5. Charge the Watch Before Handing It Over
If you’re selling or giving away the watch, charge it to at least 50% so the new user can start using it right away.
Troubleshooting Common Disconnection Issues
Sometimes, disconnecting your smart watch doesn’t go as planned. Here are some common problems and how to fix them.
Problem: The Watch Won’t Disconnect from the App
Solution: Force close the app and reopen it. If that doesn’t work, restart both your iPhone and the watch. Then try again.
Problem: Bluetooth Still Shows the Watch as Connected
Solution: Go to Settings > Bluetooth, tap the “i” next to the watch, and select “Forget This Device.” Then toggle Bluetooth off and on.
Problem: The Watch Reconnects Automatically
Solution: Some watches reconnect when in range. To stop this:
- Turn off Bluetooth on your iPhone
- Disable auto-connect in the watch’s settings (if available)
- Move the watch out of Bluetooth range (about 30 feet)
Problem: “Unpair” Option Is Grayed Out
Solution: This usually means the watch isn’t connected or is updating. Wait for the update to finish, then try again. Also, make sure your iPhone has a stable internet connection.
Problem: Data Was Lost After Disconnection
Solution: If you didn’t back up, some data may be gone. For Apple Watch, check iCloud backups. For others, check if the app stores data online. In the future, always back up before disconnecting.
Tips for a Smooth Disconnection Process
To make disconnecting your smart watch as easy as possible, follow these expert tips:
- Do it during the day: Avoid disconnecting at night when you might be tired or rushed.
- Charge both devices: Make sure your iPhone and watch have at least 50% battery.
- Stay close: Keep the watch within Bluetooth range (about 30 feet) during the process.
- Use Wi-Fi or cellular: Some apps need internet to complete the unpairing—don’t rely on Bluetooth alone.
- Take screenshots: If you’re troubleshooting, screenshot error messages to share with support.
- Read the manual: Check the manufacturer’s website for model-specific instructions.
Conclusion
Disconnecting your smart watch from your iPhone might seem like a small task, but doing it correctly can save you time, protect your privacy, and prevent future headaches.

Remember: a little preparation goes a long way. Take a few minutes to back up, reset, and double-check your settings, and you’ll be all set.
