Amazfit T-Rex 3 gets an update that improves heart rate monitor accuracy

Zepp Health has released a new firmware version 3.2.9.3 for the Amazfit T-Rex 3 smartwatch, which improves the accuracy of heart rate measurement.

Here's What We Know

Reddit users have noticed that the 13.47MB update brings two major changes. First, the heart rate data during exercise is now more accurate. Secondly, the overall stability of the system has been improved.

This is the fourth update for the T-Rex 3 in the last month, following the introduction of blood pressure monitoring in some regions. Although all the changes have not been officially disclosed, some users have noted that the battery lasts longer after the update, while others complain about faster discharge.

The innovation is being rolled out in stages and can be checked via the Zepp app.
