Apple Releases watchOS 5.0.1 Update for Apple Watch With Activity Ring Fix
watchOS 5.0.1 can be downloaded for free through the dedicated Apple Watch app on the iPhone by going to General -> Software Update.
To install the new software, the Apple Watch needs to have at least 50 percent battery, it needs to be placed on a charger, and it needs to be in range of the iPhone.
The watchOS 5.0.1 update is minor in scale and focuses on fixing bugs that have been discovered since the watchOS 5 update. According to Apple's release notes, watchOS 5.0.1 addresses an issue that caused a "small number of users" to see increased exercise minutes, fixes a bug that caused some users not to receive stand credit in the afternoon, and solves a problem that could prevent the Apple Watch from charging.
watchOS 5, the latest major watchOS update, brought a slew of new features to the operating system. It includes Activity Competitions for challenging friends, a Walkie-Talkie mode with real-time push-to-talk communication, support for Siri shortcuts, new watch faces, and tons more.
