watchOS 9.3 second beta goes live for developers

As the holiday season goes off, Apple kicks off the new beta builds to developers for testing purposes. Today, Apple releases second beta of watchOS 9.3. The incremental beta goes live one month after the announcement of first beta.

Apple plants the new beta on the compatible devices with 20S5637h build number. The latest incremental beta weighs 284MB in size, relatively bigger than the first beta. If you are a developer, then you can easily update your Apple Watch to the second beta. watchOS 9.3 is available for Apple Watch Series 4 and later models.

As always, Apple didn’t mention anything in the release notes of the new update. So, we are not aware of new changes at the moment. But the upgrade has all features available on the previously released watchOS 9.2 such as support for advanced race route workouts, optimizations to the crash detection feature, a better kickboxing algorithm, and more.

Alongside the watchOS 9.3 second beta, Apple kicks off new incremental beta builds for other platforms. The list includes second beta of iOS 16.3, iPadOS 16.3, tvOS 16.3, and macOS 13.2.
