The Amazfit Active Max is leveling up with its latest system software. Owners of the sleek wearable can now look for firmware version 3.7.0.1, which introduces a blend of high-end athletic metrics and refined lifestyle tracking to enhance the overall user experience.
New Athletic Insights: Lactate Threshold Support

The standout feature of this release is the integration of lactate threshold measurement. Previously reserved for high-performance sports watches, this metric helps runners and endurance athletes identify the specific intensity level where fatigue begins to accelerate. By tracking this, users can more effectively calibrate their training zones and avoid overexertion during intense workouts.
Precision Rest with Enhanced Sleep Staging
Beyond fitness, Amazfit has focused on recovery by improving the accuracy of sleep staging. The update refines how the watch distinguishes between light, deep, and REM sleep cycles. With these backend adjustments, the health data provided each morning should offer a more reliable reflection of your actual rest quality, helping you make better decisions about your daily energy management.
System Performance and Stability
As with most significant version jumps, version 3.7.0.1 includes various under-the-hood optimizations. These bug fixes and system tweaks are designed to ensure the interface remains fluid and the connection between the watch and the Zepp app stays stable. While these changes are less visible than new features, they are crucial for the long-term reliability of the device.
Rolling Launch: When to Expect the Update
Don’t panic if your Zepp app isn’t showing a notification just yet. Amazfit is deploying this update in phased waves. While a segment of the user base has already gained access to the new features, it may take several days for the firmware to reach every region. Users are encouraged to check for updates manually within the device settings in the app over the coming week.
