In late July 2026, Zepp Health began deploying firmware updates for premium Amazfit models, including the Cheetah 2 Ultra, Balance 3, and Balance Ultra, adding Bluetooth-speaker functions and map navigation. By mid-August, updates across eight models introduced Bluetooth FTMS protocol support for indoor rowing and enhanced swimming features like ‘Manual Rest’. 

On August 15, the Zepp OS 6 update rolled out to the Amazfit Active Max, introducing the Training Library and Multi-Device Activity Sync. On August 18, Zepp Health expanded rollouts via the Zepp app. Outdoor models, such as the T-Rex 3, T-Rex 3 Pro, and T-Rex Ultra 2, received version 6.3.13.5, which improves integration with Helio Strap and Helio Strap Pro. The Amazfit Balance 2 also received the Zepp OS 6 update (v6.2.208.7), focusing on map management and sports monitoring, though it lacks the ‘Motion UI’ launcher found on the Balance 3.

In early September, Zepp Health released firmware version 6.3.25.5 for the Amazfit Active 3 Premium. This update introduced HYROX analysis for users with the Helio Strap Pro, providing movement frequency and heart rate trends alongside pace change data. It also added FTMS support for indoor cycling, allowing the watch to display power, cadence, speed, and distance from compatible trainers. The update further included enhanced music management and the ‘Athlete Defaults’ feature to automate settings like ‘Workout Do Not Disturb’.
