Alongside iOS 9.3.2, Apple has also released a bug fix update for Apple Watch in the form of watchOS 2.2.1. The release notes indicate the OTA update (weighing in at around 30 MB) includes various bug fixes and security updates. Given the version number, we aren’t expecting any new features but we’ll update if we see anything new. Check the Apple Watch app on the iPhone to update to the latest firmware.
To install updates on Apple Watch, connect the paired, nearby, iPhone to WiFi and connect the Apple Watch to its charger. The Apple Watch hardware needs at least 50% battery in order for the update to go through.
The next major software update for Apple Watch, watchOS 3, is expected to be unveiled at WWDC including developer betas. However, that update is not expected to be released publicly until the fall alongside the launch of new Apple Watch 2 hardware. Simultaneously with watchOS 2.2.1, Apple released corresponding bug fix updates for OS X, tvOS and iOS.
