What should users check if their Apple Watch is not pairing with an iPhone?

Ensuring that both the Apple Watch and the iPhone are running the latest software version is crucial when troubleshooting pairing issues. Software updates often include important bug fixes and enhancements that can resolve compatibility or connectivity problems. If one device is on an outdated version while the other is updated, this can hinder the pairing process due to potential discrepancies in functionalities or features.

While verifying that the Apple Watch is fully charged and checking the iPhone’s storage are good practices, these are secondary considerations that are less likely to prevent pairing directly. Similarly, resetting the Apple Watch to factory settings is a more drastic measure that typically comes into play only after other troubleshooting steps have been exhausted. Therefore, starting with the software version is the most logical and effective step in resolving pairing issues.
