The basic process: what happens when you pair

When you move to a new iPhone, your Apple Watch does not automatically connect to it. You need to unpair the watch from your old phone first, then pair it with the new one. This process takes about 10 to 15 minutes and walks you through restoring your watch settings, apps, and payment information from iCloud — the same cloud backup that stores your iPhone data.

The watch and phone communicate over Bluetooth during pairing, but the actual data (your health history, saved workouts, passwords) comes from Apple's servers, not directly from the old phone. This is why you need the same Apple ID on both devices.

Key Takeaways

  • You must unpair your Apple Watch from the old iPhone before pairing it with the new one, using the Watch app on the old phone.
  • The new iPhone and watch must be within 10 feet of each other, both have Bluetooth turned on, and both must be connected to the same Wi-Fi network during pairing.
  • Pairing restores your watch data from iCloud automatically — you do not need to manually transfer anything from the old phone.
  • If you no longer have access to the old iPhone, you can unpair the watch remotely using iCloud.com or skip unpairing and erase the watch during setup on the new phone.

Unpair your watch from the old iPhone

Open the Watch app on your old iPhone. Tap the My Watch tab at the bottom, then tap the watch name at the top of the screen. Tap the information icon (a small circle with an "i" inside), then scroll down and tap Unpair Apple Watch. You will be asked to enter your Apple ID password — this prevents someone else from pairing the watch to their phone without your permission.

The unpair process takes a few minutes. Your watch will restart and erase all data stored on it locally. Do not turn off the watch or close the Watch app during this time. Once it finishes, the watch screen will show the Apple logo and then a pairing code — this means it is ready to connect to a new phone.

If you no longer have the old iPhone, you can skip this step. Instead, you will erase the watch during setup on the new phone, which accomplishes the same thing.

Prepare your new iPhone and watch for pairing

Make sure both devices are charged to at least 50 percent. Turn on Bluetooth in Settings on the new iPhone — swipe down from the top right corner, tap the Bluetooth icon to turn it on. Connect the iPhone to Wi-Fi by going to Settings, then Wi-Fi, and selecting your network. The watch will use the same Wi-Fi connection once paired.

Hold the watch and new iPhone close together, within about 10 feet. The watch should be powered on and showing the pairing code screen (the screen with large numbers). If the watch is off, press and hold the side button until you see the Apple logo, then keep holding until the pairing code appears.

Complete the pairing on your new iPhone

Open the Watch app on the new iPhone and tap Start Pairing. Point the iPhone's camera at the pairing code on the watch screen — the camera will read the code automatically. If the camera cannot read the code, tap Pair Apple Watch Manually instead and enter the code by hand.

The iPhone will now connect to the watch over Bluetooth. This takes about 30 seconds. Once connected, you will see a screen asking which wrist you wear the watch on (left or right) and whether you want to set it up as a new watch or restore from a backup. Choose Restore from Backup — this downloads your health data, installed apps, and settings from iCloud using your Apple ID.

The restore process can take 5 to 10 minutes depending on how much data you have and your internet speed. Keep both devices close together and do not interrupt the process. You will see a progress bar on both the watch and iPhone.

What happens if you do not have the old iPhone

If your old iPhone is lost, broken, or you no longer have it, you can still pair the watch to the new phone. During pairing setup on the new iPhone, when you reach the screen asking whether to set up as new or restore from backup, tap Set Up as New Apple Watch. Then when ready tap Restore from iCloud Backup on the next screen.

You will be asked to sign in with your Apple ID. The watch will read your backup from iCloud just as it would if you had unaired from the old phone first. The end result is identical — your data, apps, and settings are restored to the watch.

If you do not remember your Apple ID password, you can reset it at iforgot.apple.com before starting the pairing process. You will need access to a recovery email address or phone number associated with your account.

Troubleshooting common pairing problems

The camera will not read the pairing code: Make sure the watch screen is clean and the code is fully visible. Tap Pair Apple Watch Manually on the iPhone and type the code in by hand instead. The code is eight digits and appears on the watch screen.

Pairing starts but stops halfway through: This usually means the Bluetooth connection dropped. Move the devices closer together, make sure Bluetooth is still on, and try again. If it keeps failing, restart both devices: hold the side button on the watch until Power Off appears, swipe to turn it off, then press the side button again to turn it back on. On the iPhone, go to Settings, General, Shut Down, then turn it back on.

The watch pairs but apps do not restore: Apps restore from iCloud during the first few minutes after pairing, but only if you chose Restore from Backup. If you chose Set Up as New, the apps will not restore. You can manually reinstall them from the App Store on the iPhone — open the Watch app, go to the App Store tab, and search for each app you want.

You see an error about your Apple ID: Make sure you are signed into the iPhone with the same Apple ID you used on the old phone. Go to Settings, [Your Name], and check that the email address matches. If it does not, sign out and sign back in with the correct ID before pairing the watch.

After pairing is complete

Once the watch finishes restoring, it will show your watch face and you can start using it when ready. Your health data, workouts, and installed apps are already there. Notifications will start coming through to the watch within a few minutes.

Check that your payment information restored correctly by opening the Wallet app on the watch. If your credit or debit cards did not restore, you can add them again through the Watch app on the iPhone — go to Wallet & Apple Pay, tap Add Card, and follow the prompts.

If you had any custom watch faces saved, those restore automatically from iCloud. If you had created any automations or shortcuts on the old watch, those also restore. You do not need to set anything up manually unless something failed to restore, which is rare.

Frequently Asked Questions

Do I need to unpair before I can pair with a new phone?

Not technically — if you cannot access the old iPhone, you can erase the watch during setup on the new phone instead. However, unpairing from the old phone first is cleaner and prevents confusion about which phone the watch is connected to. If you still have the old phone, unpair it before pairing with the new one.

Will my health data and workouts transfer to the new phone?

Yes, automatically. When you choose Restore from Backup during pairing, iCloud downloads all your health history, completed workouts, activity rings, and sleep data to the new watch. This happens in the background during the first few minutes after pairing finishes.

What if I want to set up the watch as brand new instead of restoring?

You can choose Set Up as New Apple Watch during pairing instead of Restore from Backup. This erases all previous data and settings. You can still restore from iCloud backup afterward by going to the Watch app on the iPhone, tapping My Watch, selecting your watch name, tapping the information icon, and choosing Restore from Backup.

Can I pair the watch to multiple iPhones at the same time?

No. An Apple Watch can only be paired to one iPhone at a time. If you try to pair it to a second iPhone, you must unpair it from the first one first. The watch will disconnect from the old phone and connect to the new one.

How long does the whole process take?

Unpairing from the old phone takes about 5 minutes. Pairing with the new phone and restoring your data takes 10 to 15 minutes total, depending on how much data you have and your internet speed. Plan for 20 to 30 minutes from start to finish if you are doing both steps.
