Rugged smartwatches are becoming more popular than ever in 2025, and Amazfit isn’t slowing down. The brand’s next big release could be the Amazfit T-Rex 3 Pro, a tougher, smarter version of last year’s T-Rex 3.
A retailer listing in the Philippines has spilt some early details. If these leaks are on point, the T-Rex 3 Pro could deliver some serious upgrades—think a brighter display, premium materials, and new outdoor tools that make it even more appealing to adventurers.
Here’s everything we know so far.
What’s New in the Amazfit T-Rex 3 Pro?
The Amazfit T-Rex 3 Pro is already turning heads before launch. First spotted in a Philippines retailer leak and later in the Zepp app, it’s clear Amazfit is gearing up for something big.
Early teasers hint at a tougher design, more innovative training tools, and advanced health tracking—making the Pro a serious upgrade over the standard T-Rex 3.
More innovative Training with New Integrations
One of the biggest highlights of the T-Rex 3 Pro is its push toward better training support.
Amazfit is finally adding direct TrainingPeaks integration, which is a big deal for athletes. Up until now, syncing data between Zepp and TrainingPeaks required workarounds, but with this update, it should work smoothly.
There’s also talk about new Stryd integration. While Amazfit watches already support the Stryd Duo running power pod, the T-Rex 3 Pro could take that connection further.
For runners, this likely means more accurate data and better insights into performance without extra hassle.
Mini Apps for Advanced Fitness Insights
Amazfit isn’t just focusing on training platforms—it’s also adding two new Mini Apps that bring fresh ways to track and understand your data.
- Wild.AI Mini App – This one’s designed especially for women, helping align workouts with menstrual cycles. It’s already available on the Balance 2, and now it’s making its way to the T-Rex line.
- Intervals. ICU Mini App – A favourite for cyclists and endurance athletes, this app lets you analyse workouts across running, cycling, and swimming. The first version launched in June 2025 with basic syncing, but the next update is expected to add planned workouts and HRV tracking, giving you an even deeper look at your recovery and performance.
Together, these apps make the T-Rex 3 Pro more than just a rugged smartwatch—it’s turning into a real training companion.
Amazfit T-Rex 3 Pro Price & Availability (September 2025)
The wait isn’t long. The Amazfit T-Rex 3 Pro launches on September 5, 2025, with a UK price of £399.90. That puts it at the premium end of Amazfit’s lineup.
While the new apps and integrations are launching with the Pro model first, Amazfit hasn’t confirmed whether they’ll roll out to other watches. If you want these features right away, the T-Rex 3 Pro looks like the way to
Design and Display Upgrades on the T-Rex 3 Pro
The first significant change is choice. Up until now, the T-Rex line has stuck to one bulky size, but the Pro will reportedly come in two case sizes—48mm and 44mm.
That smaller option is a smart move, especially for people who liked the rugged look but found the old model too chunky for everyday wear.
The 48mm model is also said to get a serious display upgrade. Rumours suggest it will pack an AMOLED screen with up to 3,000 nits brightness, which is a 50% boost compared to the regular T-Rex 3.
If you’ve ever tried checking your watch under harsh sunlight, you’ll know how much you need that extra brightness.
On top of that, Amazfit may be using sapphire glass instead of Gorilla Glass, plus titanium alloy buttons, giving the watch a more premium, durable finish.
In other words, it’s still rugged, but with a touch of class.
New Features Rumored for the Amazfit T-Rex 3 Pro
The leaked info doesn’t stop at the design. The T-Rex 3 Pro looks set to come with features that make it more useful day to day, not just outdoors.
- A built-in flashlight with two-colour LEDs (perfect for camping or late-night runs)
- A speaker and microphone for Bluetooth calling directly from your wrist
- Route Planning backed by dual-band GPS for more accurate navigation
- Over 180 sports modes, covering everything from hiking and cycling to diving
- 10 ATM water resistance, which means it’s suitable for scuba diving and freediving
- A new BioCharge energy feature, which seems designed to track your daily energy levels
That last one—BioCharge—sounds particularly interesting. Amazfit already does a solid job with sleep, stress, and heart-rate tracking, but an “energy score” could give you a quick snapshot of how ready you are to take on the day.
Hardware, Storage & New BioTracker 6.0 Sensor
Under the hood, the Pro model is expected to run Zepp OS 4.0 and offer a massive 26GB of storage.
That’s a significant leap from what we’re used to on Amazfit watches, potentially opening up more space for offline music, maps, and apps.
It’s also rumoured to pack the latest BioTracker 6.0 sensor, which should bring more accurate readings for heart rate, blood oxygen, stress levels, and even skin temperature.
And of course, battery life remains one of Amazfit’s strongest selling points. Here’s what the leaks suggest:
- 48mm model: 700mAh battery, up to 25 days of use
- 44mm model: 640mAh battery, up to 19 days of use
That’s still excellent, even if the 48mm version falls slightly short of the 27 days promised on the standard T-Rex 3. With a brighter screen and more features, the slight trade-off makes sense.

Why the Amazfit T-Rex 3 Pro Stands Out
The Amazfit T-Rex series has always been known for its toughness, built to handle the outdoors without breaking a sweat. But with the T-Rex 3 Pro, Amazfit is stepping things up.
This isn’t just a rugged smartwatch anymore—it’s shaping up to be a true fitness partner. With TrainingPeaks integration, improved Stryd support, and new mini apps like Wild.AI and Intervals.icu, the watch is built for people who don’t just want to record workouts, but actually push their performance to the next level.
If you’ve been waiting for a smartwatch that’s both hard-wearing and training-focused, this could be one of Amazfit’s most exciting launches yet.
Final Thoughts
Here’s a quick look at what the T-Rex 3 Pro is bringing to the table:
- TrainingPeaks integration for smooth workout syncing
- Better Stryd support for runners
- Wild.AI and Intervals.icu apps for deeper insights
- A premium build with a bright AMOLED display
- Price: £399.90 (UK)
- Release date: September 5, 2025
In short, the T-Rex 3 Pro combines durability with pro-level training tools—making it one of the boldest Amazfit watches to date.
FAQ
Is the Amazfit T-Rex 3 Pro waterproof?

What’s the difference between the T-Rex 3 and T-Rex 3 Pro?
The Pro model is rumoured to bring several upgrades, including a smaller 44mm option, a brighter 3,000-nit AMOLED display, sapphire glass, titanium buttons, and new tools like a built-in flashlight, Bluetooth calling, and a BioCharge energy tracking feature.
