Amazfit T-Rex 3 Pro update adds smarter pace tools and flashlight stats

April 15, 2026 Ivan Jovin Firmware update, Smartwatch 3 min read

The Amazfit T-Rex 3 Pro is getting yet a new firmware update, version 4.7.3.1. The 15.89MB release adds segment-based pace metrics for runners, better navigation access during workouts and expanded support for HYROX and interval-style training.

Better tools for runners

Let’s start with the new workout features. One of these is the addition of segment-based equivalent pace data for Outdoor Run and Trail Run. In simple terms, this gives runners a more contextual view of pace over specific segments rather than relying purely on the constantly fluctuating live pace number.

That matters more than it might seem at first glance. Instant pace can jump around quite a bit, especially in urban environments, under tree cover or on trails where GPS conditions are less than ideal. Segment-equivalent pace tends to provide a steadier reference point, making it easier to judge effort and hold a target speed.

The inclusion of both current segment equivalent pace and last segment equivalent pace is particularly useful. It gives runners a quick way to compare consistency between efforts without needing to dig into post-run data afterward.

Navigation gets easier mid-workout

Another addition is the new “Navigation” entry within the track page menu during workouts. Previously, accessing route guidance or navigation options during an activity could feel a little buried depending on the mode and setup. It should now be a bit to reach from the workout interface, which is important for trail runners, hikers and anyone using routes on the move.

HYROX and interval users get something too

The update also expands AMRAP mode support for HIIT, HYROX Training, Hybrid Training and Cross Training, with timer modes and templates. These now support durations of up to 99 minutes. Longer AMRAP sessions are common in hybrid fitness and endurance-focused circuit work, so removing tighter duration limits makes the watch better suited to real programming.

Given how much Zepp Health has been leaning into HYROX recently, this part of the update feels especially relevant. It suggests the company is continuing to fine-tune the watch around that training ecosystem. Interestingly, there may be a new device drop soon as it has been teased at a recent HYROX event. By the looks of it it might be a new variant of Balance 2.

There’s more

This is not where the updates end.

Battery Manager now includes usage duration statistics for the LED flashlight, which is a neat addition for anyone who actually uses the built-in torch regularly during night walks, early runs or camping trips.

The new toggle for watch face status indicators is another change. Some users like having icons and indicators visible at all times, while others prefer a cleaner watch face. Giving people the option to choose makes sense.

Workout interaction has also been refined, with a countdown prompt now added when pausing or ending via long press. That should help reduce accidental workout endings, something every runner has probably experienced at least once and usually at the worst possible moment.
