Amazfit Helio Strap Receives Software Update v3.0.6.4 with Improved Heart Rate Features
Amazfit is continuing its commitment to enhancing the user experience with its recently released Helio Strap by rolling out another software update. Just weeks after its global launch in June 2025, the fitness-focused wearable is now receiving firmware version 3.0.6.4, bringing key improvements to its heart rate monitoring features, along with additional performance optimizations and bug fixes.
This marks the second major update for the Helio Strap since its debut, following version 3.0.2.2, which was released shortly after the wearable hit the market. With the new update, Amazfit aims to address specific user feedback and further improve the device’s core functionality—particularly in the area of heart rate data collection and synchronization.
Key Improvements in Version 3.0.6.4
According to reports from early adopters on platforms like Reddit, the new 2.24 MB update file delivers two notable changes that directly impact the accuracy, usability, and reliability of heart rate monitoring. These enhancements are expected to be welcomed by athletes and fitness enthusiasts who depend on precise biometric data during training and daily health monitoring.
1. Enhanced Heart Rate Broadcast Stability
The first major upgrade focuses on improving the stability of the heart rate broadcast function. This feature enables the Helio Strap to stream real-time heart rate data to other compatible devices, including popular smartwatches such as those from Garmin.
Prior to this update, some users experienced intermittent connection issues or syncing delays when pairing the Helio Strap with third-party devices. With version 3.0.6.4, Amazfit claims to have optimized the underlying connection protocols, resulting in a more stable and consistent transmission of heart rate data. Early feedback suggests noticeable improvements, with users reporting smoother and more accurate heart rate syncing during workouts and endurance activities.
This change makes the Helio Strap an even more competitive choice for fitness enthusiasts who rely on external devices or apps for real-time biometric tracking during training sessions.
2. Extended All-Day Heart Rate Data Logging
The second update relates to the storage capacity for heart rate data. With version 3.0.6.4, users can now log and retain all-day heart rate data for up to 21 days—a significant improvement over previous storage limits.
This enhancement provides users with a more comprehensive view of their heart health trends over time, making it easier to monitor changes in resting heart rate, spot irregularities, or assess recovery patterns. Whether you’re an athlete tracking performance or a health-conscious user monitoring wellness metrics, the ability to store and review multiple weeks of data adds meaningful value.
Additional Fixes and Improvements
While the two heart rate-related changes headline this update, the official changelog for version 3.0.6.4 also mentions “other feature enhancements and bug fixes.” Although specific details have not been provided, these general optimizations are expected to improve the overall performance, stability, and responsiveness of the Helio Strap.
It is common practice for Amazfit to roll out firmware updates in phased deployments, meaning not all users will receive the update simultaneously. At this stage, it remains unclear exactly how many Helio Strap users have access to version 3.0.6.4. If you haven’t received a prompt yet, you can check manually via the Zepp app, which is used to manage Amazfit wearables.
Helio Strap: A Promising Entry in the Fitness Wearables Market
Priced at $99.99 on Amazon, the Amazfit Helio Strap has positioned itself as a competitive offering in the budget-friendly fitness strap market. Its lightweight design, focus on biometric accuracy, and compatibility with third-party fitness ecosystems like Garmin and Strava make it a compelling alternative to more expensive heart rate monitors.
With timely updates like v3.0.6.4, Amazfit is reinforcing its commitment to product longevity and user satisfaction—an essential quality in the rapidly evolving world of wearable tech.
Bottom Line: The Amazfit Helio Strap is becoming a more reliable and feature-rich fitness companion thanks to continued software support. If heart rate tracking and long-term data analysis are essential to your fitness journey, this update brings tangible improvements worth noting.
