To start the process, you must ensure that both your iPhone and Apple Watch are at least 50% charged. Having both devices at least half charged will prevent any disruption in the pairing process. Make sure your iPhone is running the latest version of iOS for compatibility reasons.
You can then start by turning on your Apple Watch and holding it near your iPhone. A pop-up screen should appear on your iPhone, displaying a 'Use your iPhone to set up this Apple Watch' message. Click 'Continue'. If you don't see this message, you can manually open the Apple Watch app on your iPhone and select 'Start Pairing'.
Next, align the watch with the camera on your phone to scan the pattern that appears on the watch screen. Once successful, you will have to set up a couple more options like wrist preference, passcode, and App layouts before wrapping up the pairing. Your devices will now start syncing data.
Now that your iPhone and Apple Watch are paired, they will automatically sync. Changes you make on your iPhone, such as updating apps, changing settings, adding reminders or alarms, will reflect on your Apple Watch, and vice versa. Please note that your devices need to be in close range for syncing to occur.
Apple has a unique feature that helps you sync specific data for your daily use. For instance, you can select to sync the latest music or your favorite playlist. This can be done by going to the Apple Watch app on your iPhone→ 'My Watch'→ 'Music'→ 'Add Add Music'. Select the songs, albums, or playlists that you want to sync, and the next time your Apple Watch is on the charger and in the range of your iPhone, your selection will sync.
In case you encounter any syncing issues between your devices, there are a few troubleshooting steps you can take. A restart of both devices usually resolves minor glitches. If the problem persists, unpair and then re-pair the devices.
The other thing you can consider checking is the Bluetooth connection. Open the Control Center on your iPhone and check if Bluetooth is enabled. If everything else fails, contact Apple Support for further assistance.
