The Amazfit Active 3 Premium is getting a performance boost this week as Zepp Health begins the phased rollout of its latest software enhancement. Carrying version number 3.7.0.8, this update focuses on streamlining the user interface and refining the analytical tools athletes rely on most.
Smarter Lactate Threshold Tracking

The standout feature of this release is the significant optimization of Lactate Threshold monitoring. To provide a more seamless experience for runners and endurance athletes, the “auto-detection” toggle is now switched on by default. This means the watch will automatically calculate your aerobic limits during intense sessions without requiring manual calibration, allowing for more precise heart rate zone training right out of the box.
Refined Workout Organization
User feedback has led to a slight shuffle in the wearable’s exercise menu. Hybrid Training has been moved higher up in the default workout list, reflecting the growing trend of versatile, multi-discipline fitness routines. This change cuts down on scrolling time, letting you jump into your favorite cross-training sessions much faster than before.
System Stability and Rollout Details
Beyond the visible tweaks, version 3.7.0.8 includes a suite of under-the-hood system optimizations aimed at squashing minor bugs and improving overall device fluidity. As is standard with Amazfit releases, the update is being deployed in stages. If you don’t see the notification in your Zepp app immediately, don’t worry—it should reach all global units within the next few days.
