First Amazfit Helio Strap firmware update lands as premium model lingers
Helio Strap just received its first firmware update since launch. Version 3.0.6.4 is now live in the Zepp app, focused on connection stability and better data storage. Meanwhile, we’re still waiting on the official premium version to launch, though third-party strap options have already started appearing.
Focus on sync reliability and onboard history
The most prominent fix addresses the heart rate broadcast feature. This is the mode that allows the Helio Strap to share real-time heart rate with third-party apps or devices. The update should make those connections more reliable, especially during longer sessions or when paired to multiple ecosystems like Garmin or Apple Health.
Zepp Health has also adjusted how long the strap can hold on to heart rate data. With this update, the Helio Strap will retain continuous all-day heart rate history for up to 21 days. That’s useful for those who don’t sync daily or want to run data dumps once or twice a week. It also hints at the strap’s long-term tracking ambitions, even if the app interface still has a way to go.
Aside from that, the update log mentions unspecified “feature enhancements and bug fixes,” but nothing else new has surfaced on the user side so far. The package is light at 2.24MB and installs quickly once triggered.
A reminder the premium version is still missing
While this firmware update is a good sign of active support, many users are still waiting on the premium Helio Strap to launch. Zepp Health’s early rollout focused on a single black variant with a wrist-worn shell and quick-release strap. That followed the Hyrox edition which launched earlier with the same sensor but a slightly different look.
What’s interesting is that third-party alternatives are starting to appear on Amazon. These include alternative bands and upper arm sleeves that work with the Helio module. It’s a side effect of the modular approach Zepp is taking, where the core sensor can slot into different mounts. Some users have even fitted the sensor into Whoop accessories.
The more flexible premium model is still expected. Leaked instructions suggest it will include a three-part midcase that allows for both wrist and upper-arm wear, but won’t add new functionality. It’s just a more adaptable version of the same product. Pricing hasn’t been confirmed, but it’s likely to come in slightly above the standard model’s $100 price.
