The rugged Smartwatch from Amazfit, the T-Rex 3 Pro, is getting a significant software refresh.
The new firmware, version v4.1.6.7, rolls out a mix of New Features, Optimization, and bug fixes that improve health tracking, navigation, diving, and daily performance.
Suppose you use your T-Rex 3 Pro for workouts, outdoor trips, or everyday health tracking. In that case, this update is worth installing as soon as it becomes available on your device.
Better Health and Wellness Tracking with BioCharge update
This Firmware Upgrade emphasizes health and recovery. The BioCharge app now gets two new pages that give you more detailed insights into how your body feels throughout the day.
The update adds:
- Wake BioCharge
- Daily Events
The Wake BioCharge page helps you understand how well your body recovered overnight. It gives you a clearer idea of how ready you are to take on the day.
The Daily Events page tracks how your energy and recovery change throughout the day.
With this BioCharge update, you get a fuller picture of how sleep, stress, and activity affect your body, not just a single score.
These upgrades make the T-Rex 3 Pro more helpful for people who care about recovery, training load, and daily energy levels.
Stronger Navigation and Diving Mode Improvements
Outdoor users and divers get some functional upgrades, too. The latest firmware improves both the Diving Mode experience and on-wrist navigation.
In Recreational Diving Mode, a new Descent Page called “Waiting for Descent” has been added. This new screen makes the pre-dive phase smoother and more organized, so you can check key details before going under.
Navigation also gets a boost. The Route Re-planning feature now works more reliably when you go off your planned trail or path.
The watch adjusts the route more intelligently, helping you get back on track faster, which is excellent for hikers, runners, and cyclists.
On top of that, the Map app now has a cleaner, quicker start-up process. The initialization interaction is more direct, so you can get your map view ready more quickly.
Faster Performance and Better Responsiveness
The v4.1.6.7 update focuses heavily on everyday speed and responsiveness. Several core features have been fine-tuned to make the watch feel more responsive in real use.
One key improvement is the Wrist Raise-to-Wake feature. The firmware optimizes how fast the screen turns on when you lift your wrist, both during regular daily use and during workouts.
This reduces delays and makes the display feel more in sync with your movement.
Real-time fitness readings are also more accurate. The watch now provides more reliable physical fitness status values during activities, helping you trust the data you see while running, cycling, or training.
Display, Sound, and System Stability Improvements
This Firmware Upgrade also brings a few quality-of-life changes that make the Smartwatch feel more polished.
The display gets smarter with improved Auto-Brightness. The watch now reacts faster to changing light conditions, so the screen adjusts brightness more quickly when you move between indoors and outdoors.
Media control sees a minor but handy tweak.
When the watch volume is set to 0, multimedia playback now pauses automatically. This prevents silent playback and saves a bit of battery and confusion.
Behind the scenes, System Stability has been improved. The firmware fixes certain system crash issues that occurred in specific situations and resolves several other known problems.
Overall, the T-Rex 3 Pro should now feel more stable and consistent in daily use.
Rollout, Availability, and the Zepp App
The release of firmware v4.1.6.7 is happening in stages. Some Amazfit T-Rex 3 Pro owners have already received the update. In contrast, others will see it appear over the coming days.
To get the update as soon as it is ready for your watch, make sure your Zepp App is up to date. Then:
- Open the Zepp App on your phone.
- Go to your device page for the T-Rex 3 Pro.
- Check for any available firmware updates.
- Follow the on-screen steps to install v4.1.6.7.
Keeping your firmware up to date is one of the easiest ways to get New Features, better Optimization, and improved System Stability from your Smartwatch.
Suppose you depend on the T-Rex 3 Pro for health tracking, diving, or outdoor activities. In that case, this Firmware Upgrade is an essential step toward making the watch more helpful, responsive, and reliable.
