Amazfit Helio Strap has received firmware version 3.18.0.1, a small 3.68MB update focused on workout tracking rather than new features. The main changes are a fix for duplicate activity records when a watch is already tracking a session, plus tweaks to the heart rate monitoring algorithm.
What changed
It has been a while since the Helio Strap last received a firmware update, so this one is worth noting. Version 3.18.0.1 is not trying to turn the device into something new. It looks more like a tidy-up release aimed at making the strap behave better inside the wider Amazfit ecosystem.
The first change is probably the more useful one. Zepp Health says the Activity Detection feature has been optimised so the Helio Strap will no longer create duplicate activity records when your watch is already tracking a workout. That sounds like a niche fix until you actually run into it. Then it becomes exactly the sort of thing that makes post-workout data messy.
The Helio Strap sits in a slightly unusual place. It is not a watch. It is not a screen-first wearable. It works best as a lightweight fitness strap that feeds data into the Zepp Health app and can sit alongside a more capable Amazfit watch. That makes clean workout handling important. Users do not want two versions of the same session fighting for attention inside their history.
This update should help people who use the Helio Strap with an Amazfit watch rather than as a standalone tracker. If the watch already records the run, ride or gym session, the strap should now avoid generating a separate duplicate activity record from its own detection system.
This also suggests Zepp Health is still tuning how the Helio Strap behaves in a multi-device setup. That is where the product needs to be reliable. A strap like this does not win people over with a big display or rich on-device features. It needs to disappear into the background and record the right data at the right time.
Heart rate tracking also gets attention
The second listed change is an optimisation to the heart rate monitoring algorithm. Zepp Health says this should improve heart rate tracking accuracy, though the release notes do not give extra detail on what has changed.
It will be interesting to see whether the update improves higher-intensity exercise tracking. Optical heart rate sensors can struggle when movement, strap tension and sweat all get involved. The Helio Strap has a simpler job than a smartwatch in some ways because it does not have to manage a screen-heavy experience. But it still lives or dies by whether people trust the numbers.
Worth installing
The final note simply says other known issues have been fixed. That is the usual catch-all line in firmware updates, but the two named changes are enough to make version 3.18.0.1 worth installing.
All things considered, this is a maintenance release with one very practical fix. But for anyone using the Amazfit Helio Strap alongside a watch, removing duplicate workout records should make the experience cleaner straight away. As always, different regions may receive the update at different times. We have reports of those in the UK and a few other countries already receiving the new firmware.
In other news, the company is working on the gen 2 device. We recently spotted the FCC regulatory filing for that one and expect a launch in the second half of the year.
