Amazfit smartwatches get new BioCharge related tools in update

A new update for the Amazfit T-Rex 3 Pro smartwatch has arrived: software version 4.1.6.7. This wearable was last updated in mid-November 2025 with the version 3.3.4.1 release, gaining a new screenshot feature and navigation support for more outdoor sports.

As reported on Reddit, the latest update brings two new BioCharge related features. These are Wake BioCharge and Daily Events pages, each of which can be found within the BioCharge app. Amazfit has also improved the automatic re-routing experience for route navigation, and there are other minor optimizations for the Map app. The accuracy of your real-time physical fitness status values during a workout has also been improved.

Users of the T-Rex 3 Pro should find the wrist raise-to-wake functionality to be working more smoothly, and automatic screen brightness adjustments are said to be quicker. Plus, when you decrease the watch volume to zero, your music or podcast will now be paused automatically. On top of this, for Recreational diving, there is a new “Waiting for Descent” page. The release notes also vaguely mention bug fixes, some of which tackle system crashes.

Software version 4.1.6.7 appears to be rolling out in phases to users of the T-Rex 3 Pro smartwatch (44 mm Tactical Black, curr. $399.99 at Amazon). When it reaches your country, this 15.82 MB file will be available to download via the Zepp Health app.
