Apple today seeded the second beta of an upcoming watchOS 5.2.1 update to developers, a week and a half after seeding the first beta and almost two weeks after the release of the watchOS 5.2 update, which introduced AirPods 2 support and expanded the ECG feature to Europe.
Once the proper configuration profile has been installed from the Apple Developer Center, the new watchOS beta can be downloaded through the dedicated Apple Watch app on the iPhone by going to General --> Software update.
To install the update, the Apple Watch needs to have at least 50 percent battery, it must be placed on the charger, and it has to be in range of the iPhone.
It's not yet clear what features will be introduced in the watchOS 5.2.1 update, but as 5.x.x software, it's likely to focus on bug fixes and other under-the-hood performance improvements.
No changes were found in the first watchOS 5.2.1 beta, but should we find new features in the second watchOS 5.2.1 beta, we'll update this post with details.
