| Amazfit’s Active 2 smartwatches (Round pictured) are receiving the 6.7.0.1 update. |
If you own an Amazfit Active 2, get ready for a significant software upgrade. The latest firmware, version 6.7.0.1, is now rolling out globally, bringing a powerful new health metric and highly-requested integrations that transform the watch into a more capable training companion.
The update, arriving a few months after the last feature drop, introduces BioCharge, a sophisticated energy-level analysis that replaces the older Readiness score. Beyond personal metrics, the update bridges a major gap by allowing seamless connectivity with popular third-party training platforms and hardware.
Your Body's Battery: Introducing BioCharge
The headline feature of this update is the introduction of BioCharge. This new metric goes beyond simple activity tracking to provide a holistic view of your body's readiness to perform. Think of it as your personal "body battery" score, synthesizing data from sleep, recovery, and daily exertion to give you a clear, actionable number.
This move from the older "Readiness" function to BioCharge suggests a more algorithmically advanced calculation, aiming to offer users a more accurate guide on when to push hard in a workout or prioritize rest and recovery.
A Hub for Athletes: Training Peaks, Stryd, and Intervals.icu
Perhaps the most exciting news for fitness enthusiasts is the new level of third-party integration. The Amazfit Active 2 can now sync directly with two premier online training platforms: Training Peaks and Intervals.icu.
The integration with Intervals.icu is particularly noteworthy. As detailed on their platform, Intervals.icu is a powerful, free-to-use sports analytics service used by over 120,000 athletes. It performs deep analysis on activities from connected devices, providing insights you won't find on standard fitness apps.
How the Intervals.icu Integration Elevates Your Training
By connecting your Amazfit to Intervals.icu, your run and cycle data transforms into a wealth of advanced metrics. The platform automatically calculates your Fitness, Fatigue, and Form (FFP) over time, creating a chart that even shows the future impact of your planned workouts. It estimates your Functional Threshold Power (FTP) without requiring a dedicated test, simply by analyzing your maximal efforts during regular activities.
For runners, the integration is a game-changer. The platform supports gradient-adjusted pace for more accurate run analysis and can calculate training load from heart rate or pace data. It also builds detailed power curves to help you track performance improvements across different durations.
Furthermore, Intervals.icu can pull in wellness data from your Amazfit, such as sleep score, resting heart rate, and HRV, and plot it alongside your training metrics. This creates a complete picture of how your lifestyle and recovery impact your athletic performance, all within a single, comprehensive dashboard.
Pairing with Precision Tools
Complementing the software integrations, Amazfit has also enabled direct pairing with the Stryd running power meter. This allows serious runners to access real-time, accurate running power data on their wrist—a key metric for measuring effort independently of hills, wind, or fatigue.
Refinements Under the Hood
Beyond the major new features, version 6.7.0.1 includes meaningful quality-of-life improvements:
- Optimized Sleep Score: Amazfit states it has refined the algorithm behind the Sleep Score to enhance its accuracy, promising users more reliable insights into their sleep quality.
- Quick Action Shortcut: A new hardware shortcut lets you double-press the lower button to instantly access a customizable function, making the watch quicker to use on the go.
- General System Improvements: The update includes other undisclosed system-wide optimizations for smoother performance.
Community Buzz and Rollout Status
News of the update has generated discussion within the Amazfit user community on platforms like Reddit. While specific Reddit threads detailing the update or discussing its staggered release aren't directly accessible, such community forums are typically where users share their experiences, confirm the update's arrival in different regions like the US, UK, and Ireland, and offer tips.
As with most firmware updates, version 6.7.0.1 is rolling out in phases. Not all users will see the notification in the Zepp App immediately. If you haven't received it yet, you can try manually triggering a check via the Zepp App's device settings. A stable internet connection and ensuring your watch has sufficient battery are the best ways to prepare for when the update arrives for you.
This update solidifies the Amazfit Active 2's position as a versatile and smart choice for health-conscious users and dedicated athletes alike, blending robust first-party health tracking with an open approach to the broader fitness ecosystem.
