How do you unpair your Apple Watch when you have your iPhone?
Okay, we admit that it is a heck of a lot easier to unpair your Apple Watch when both your watch and your paired iPhone are in your hands.
That’s because most Apple Watches have Apple’s activation lock enabled via your paired iPhone’s and iCloud’s Find My app. 
Activation lock prevents others from using your Watch (if lost or stolen) and helps you locate it when missing by requiring your Apple ID and password.
Luckily, the unpairing process erases your Apple Watch, removes it from your iCloud account, and disables Activation Lock.
Plus, when you unpair your watch from your iPhone, Apple automatically creates a new backup of your watch. You can use this backup to restore your watch’s data.
Steps to unpair your Apple Watch using the Watch app on your iPhone
- Place both your Apple Watch and iPhone on their chargers OR make sure they each have 50% of their battery capacity available. Make sure your Apple Watch and iPhone are near one another. We recommend inches or centimeters instead of feet/meters.
- On your paired iPhone, open the Apple Watch app.
- Choose the My Watch tab and tap All Watches at the top of the screen.
- Next to the name of the watch you wish to unpair, tap the “i” info button.
- Tap Unpair Apple Watch.
- For Apple Watches with GPS & Cellular services, choose to keep or remove your cellular plan.
- Keep your plan if you want to pair your Apple Watch and iPhone again.
- Remove your plan if you don’t want to pair your Apple Watch and iPhone again.
- Tap to confirm you want to unpair.
- Enter your Apple ID password to disable your watch’s iCloud Activation Lock, if asked.
- During the unpairing process, Apple automatically creates a backup of your watch. You can use this backup to restore your data if desired. Or you can start fresh and not restore the backup–it’s your choice.
- After your Apple Watch unpairs, you see the Start Pairing message on your watch.

FAQs 
What does unpairing the Apple Watch do?
When you unpair your Apple Watch from its paired iPhone, you return it to its factory settings.
That means unpairing erases all data from your Apple Watch.
Every time you unpair your Apple Watch from your iPhone, Apple automatically creates a backup of your Apple Watch’s data before removing it. You can use this backup or any previous backup to restore your Apple Watch’s data.
And when you back up your iPhone to iCloud, iTunes, or Finder your iPhone, those iPhone backups also include your Apple Watch backup.
If you unpair your Apple Watch when it’s away from your iPhone or out of range of your iPhone, your Apple Watch backup might not have the latest data.
Does unpairing the Apple watch erase it and delete all my data?
Unpairing erases all data from your Apple Watch–but not forever!
While unpairing your Apple Watch does indeed erase everything on it, a backup of all that data is automatically created when you unpair your Apple Watch using the Watch app on your iPhone.
You can then pair a new Apple Watch or that same Apple Watch again and restore that backup.
So yes, the device is erased. But as long as you use the Watch app on your iPhone, you do not lose any data since it completely backs up all your data.
Now, if you unpair your Apple Watch when you don’t have your iPhone with you or are out of range, Apple cannot back up your Watch to your iPhone. Consequently, you lose any data created after you last backed up your watch.
When you unpair an Apple Watch, does it also delete your text messages?
Like the answer above, when you unpair your Watch, it deletes everything from it, including any messages--but only from the Apple Watch.
When you unpair your watch, it does not erase, delete, or remove ANY of the messages stored on your iPhone, iCloud, or any other device using the same Apple ID as your Apple Watch.
How do I unpair an Apple Watch from a lost or stolen iPhone?
If your iPhone was stolen or lost, you should follow the steps we list in the section “How to unpair your Apple Watch without your iPhone.”
Before you start, make sure you visit Apple’s iCloud website and use Find My to mark your iPhone as Lost or remotely erase it.
Go to Settings > General > Reset > Erase All Content and Settings > Erase All on your Apple Watch. Tapping Erase All resets your Apple Watch to the factory settings.
Once done, pair your Apple Watch with your replacement iPhone.
You can also remotely erase your watch using iCloud’s website and the Find My app.
Since you did not unpair your Apple Watch using the Watch app, you cannot make a backup of your most recent watch settings and data. Look for older available backups to restore or set up your watch as new.
How do I unpair a lost or stolen Apple Watch from my iPhone?
First, when you lose your Apple Watch or suspect it was stolen, use the Find My app to try and locate your watch or place it in lost mode.
If you’ve tried locating your missing watch but conclude it’s forever lost/stolen, you want first to erase it and then unpair it from your iPhone and Apple ID & iCloud account.
