how to connect apple watch to new phone?

TLDR: To connect your Apple Watch to a new iPhone, first back up your old iPhone and ensure both devices are updated and charged. Unpair the Apple Watch from the old iPhone, then pair it with the new iPhone using the Watch app. Restore from backup if needed, and follow troubleshooting steps if issues arise.

To connect your Apple Watch to a new iPhone, start by backing up your old iPhone to iCloud or your computer, and ensure both devices are updated to the latest software. Charge both devices to at least 50% to avoid interruptions. If you still have access to your old iPhone, open the Watch app, select the 'My Watch' tab, and unpair your Apple Watch. Once unpaired, turn on your new iPhone and Apple Watch, open the Watch app on the new iPhone, and follow the prompts to start pairing.

If you no longer have access to your old iPhone, you can still pair your Apple Watch by erasing it first. To preserve health data, create an encrypted backup of your old iPhone and restore it during the setup of your new iPhone. If you encounter issues during the pairing process, ensure both devices are close, check Wi-Fi and Bluetooth connections, and consider restarting the devices. Following these steps will help you maintain your Apple Watch's functionality and data integrity during the transition.
