Amazfit has started pushing out a new software update for its Amazfit Active 3 Premium smartwatch. The new firmware, labeled as version 3.21.0.3, brings a handful of useful features designed to improve health tracking and workout performance.
Like most tech updates, this rollout is happening in phases. A few lucky users have already downloaded it, while everyone else should see it pop up on their devices over the next few days.
Better Health Tracking with HybridCharge

The biggest change in this update focuses on how the watch tracks your energy. Amazfit has upgraded its old “BioCharge” feature into something called HybridCharge.
The company says this new system gives you a much clearer, more complete picture of how your body is holding up throughout the day. It is designed to help you easily understand when you are ready to push hard and when you need to rest.
New Gear Support for HYROX Athletes
If you are into extreme fitness, this update has a major bonus. The watch now fully supports the Helio Strap Pro.
This specialized strap is a big deal for people who compete in HYROX fitness races or simulations. By pairing it with the watch, you will get in-depth, personalized data on how your heart and muscles handle the strain of heavy training.
Smoother Workouts and Bug Fixes
Amazfit is also making daily workouts feel a bit more natural. They have tweaked their training templates and interval training settings. Now, you can easily keep exercising even after your official workout routine ends, without the watch cutting you off.
Finally, the update packs in the usual round of minor bug fixes and behind-the-scenes performance tweaks to make the whole watch run faster and smoother.
