Amazfit Active 3 Premium gets a fresh update with Helio Strap Pro support

The Amazfit Active 3 Premium is getting a nice software bump that hooks it up with the new Helio Strap Pro and reworks its internal health tracking. This update rolls out as version 3.21.0.3 and only takes up a quick 15.29 megabytes to download through the Zepp companion app.

Tracking metrics get a new name

Once of the changes here is the continued rebranding and expansion of the watch’s biometric tracking. The old BioCharge tool has turned into HybridCharge, which promises to give you a much more thorough look at your daily body strain and recovery.

This shift blends your standard workout data with daily lifestyle stress. If you wear the watch all day, the software will try to factor in things like poor sleep or work stress rather than just looking at the physical strain from a run.

Support for the new Helio Strap Pro

An interesting update is support for the recently launched Helio Strap Pro. This makes Active 3 only the third watch to receive the feature, after Balance 3 and Balance Ultra. Syncing the external strap to the watch unlocks specific data during high-intensity training like HYROX competitions or workout simulations.

Moving the tracking from the wrist to a dedicated strap solves the classic issue where heavy lifting or arm flexing throws off wrist sensors. The new firmware analyzes cardiorespiratory strain alongside your actual muscular load to show exactly how your body handles intense functional movements. We are yet to see if the strap gets features outside of HYROX.

Better interval training controls

Beyond accessories and health scores, the 3.21.0.3 firmware tweaks how the watch handles structured workouts. The updated interval training process now lets you keep recording your exercise seamlessly after a programmed workout finishes.

This small tweak fixes the annoying issue where rigid fitness apps force a hard stop the second a timer ends. Letting you transition straight from a tough interval into an open-ended cooldown makes the whole workout experience feel much more natural. The update also packages the usual minor bug fixes and optimizations to keep the interface snappy and users happy.

Next month the watch is due to receive the full Zepp OS 6 treatment.
