Amazfit Helio Strap Update Enhances Sleep Tracking Accuracy and Activity Recognition

Amazfit has rolled out its first firmware update of 2026 for the Helio Strap wearable, bringing substantial refinements to its sleep tracking capabilities and activity detection systems. The 3.11.0.1 update arrives nearly two months after version 3.7.0.1 introduced multiple workout modes, shifting focus this time to optimizing fundamental health monitoring functions.

The core enhancement involves a reworked sleep recognition algorithm that improves both sleep detection sensitivity and sleep stage classification accuracy. According to official release notes shared by users on Reddit, the update enables more precise differentiation between light, deep, and REM sleep cycles. This advancement comes with a notable tradeoff: users may observe increased reporting of brief awakening periods during sleep as the system becomes more responsive to micro-arousals that previously went undetected.

Concurrently, the update reduces instances where short daytime naps are incorrectly categorized as nighttime sleep sessions. This refinement addresses a common pain point for users who rely on accurate sleep pattern analysis for health insights.

Beyond sleep tracking, firmware 3.11.0.1 enhances the strap's automatic activity recognition functionality. The underlying algorithms now demonstrate improved discrimination between similar motion patterns, resulting in fewer misidentified activities. This means walks are less likely to register as runs, and stationary periods won't accidentally log as low-intensity workouts.

The update also resolves an unspecified Bluetooth connectivity issue, though Amazfit hasn't detailed the exact nature of the fix. This suggests background optimizations to wireless communication stability between the strap and paired devices.

Available through phased rollout via the Zepp mobile app, the update demonstrates Amazfit's continued refinement of their fitness wearable platform. For users prioritizing sleep analytics, these algorithm improvements potentially position the €99.90 Helio Strap as a more compelling alternative to premium sleep trackers, particularly given its focus on capturing nuanced sleep architecture rather than merely tracking duration.
