| Amazfit is updating the T-Rex 3 and T-Rex 3 Pro smartwatches |
Amazfit is once again refining its rugged smartwatch lineup with the rollout of a fresh firmware update for the T-Rex 3 Pro. Just weeks after delivering version 4.4.1.3—a release primarily focused on squashing bugs—the company is now pushing firmware version 4.4.2.3 to users of both the 48 mm and 44 mm variants of the popular outdoor wearable. And this time, it’s not just about stability; it’s about adding meaningful new tools for athletes and streamlining everyday interactions.
The update, first spotted via an official post on Amazfit’s Weibo channel, brings a handful of carefully targeted improvements. While the changelog may appear modest at first glance, frequent users of the T-Rex 3 Pro will quickly appreciate the refinements—especially those who take their training indoors.
What’s New in Firmware Version 4.4.2.3?
According to Amazfit, the update for the T-Rex 3 Pro 48 mm is identical in content to the recent patch released for the original T-Rex 3. That means the spotlight this time is firmly on indoor cycling enthusiasts.
Smarter In-Workout Charts for Indoor Cyclists
One of the headline additions is the introduction of new in-workout charts tailored specifically for indoor cycling sessions. When paired with external sensors—such as speed sensors, power meters, or cadence sensors—the watch will now display real-time data visualizations directly on screen. This allows athletes to monitor their performance trends without glancing away from their handlebars or breaking their rhythm. Whether you’re grinding through a structured training plan or just spinning for fitness, the ability to see sensor-derived metrics charted live is a significant upgrade.
Weather Forecast Optimizations
Amazfit has also tweaked how the T-Rex 3 Pro handles weather data during workouts. Previously, if weather information was unavailable at the start of an activity, the watch might still attempt to display outdated or blank fields. With version 4.4.2.3, the system now intelligently hides weather data when it cannot be retrieved, ensuring a cleaner and less distracting interface. It’s a small change, but one that reduces visual clutter when you’re trying to focus on your performance.
Navigation Gets More Intuitive
For those who rely on the T-Rex 3 Pro’s mapping and navigation features, the update brings a welcome shortcut. Users can now access navigation settings directly by pressing the SEL button from the Map app or from workout track pages. This eliminates the need to dig through menus mid-route. Additionally, the default navigation view has been switched to “North Up”, a orientation many outdoor enthusiasts prefer for its consistency with traditional map reading.
The 44 mm Model Gets Its Own Special Touch
While the 48 mm version shares most of the update’s core features, owners of the smaller Amazfit T-Rex 3 Pro 44 mm are receiving an extra layer of polish. This variant, currently available for $399.99 at Amazon, includes an optimization aimed at the built-in flashlight.
Users of the 44 mm model will now need to press and hold the UP button for a longer duration to activate the light. According to Amazfit, this change is a direct response to user feedback regarding accidental triggers. It’s a thoughtful ergonomic tweak that should make the flashlight function more reliable when you genuinely need it—and less of a nuisance when you don’t.

How to Get the Update
As with most Amazfit firmware rollouts, version 4.4.2.3 is being distributed in phases. This means not every user will see the update notification immediately. Amazfit typically staggers releases by region to monitor for any unforeseen issues before a wider push.
If you own a T-Rex 3 Pro and haven’t received the prompt yet, don’t worry. You can manually check for the update by opening the Zepp app on your paired smartphone, navigating to your device settings, and selecting “Check for updates.” Once the firmware is available in your region, it will appear there for download and installation.
A Quiet But Meaningful Step Forward
Amazfit continues to demonstrate a commitment to post-launch support for its wearables. While the T-Rex 3 Pro was already a formidable competitor in the rugged smartwatch space—boasting military-grade durability, dual-band GPS, and impressive battery life—updates like this one prove that the software experience is just as important as the hardware.
By listening to community feedback and delivering targeted enhancements, Amazfit is ensuring that the T-Rex 3 Pro remains a relevant and capable companion for both outdoor adventurers and indoor athletes alike.
Whether you’re spinning on a trainer or navigating unfamiliar trails, firmware 4.4.2.3 quietly makes the experience a little smoother. And in the world of smartwatches, that’s exactly the kind of progress that counts.
