[SOLVED] : What are the differences between Amazfit T-Rex and Amazfit T-Rex Pro? Part one.
Amazfit T-Rex: a sports smartwatch that focuses on strength and endurance
The Amazfit brand, a subsidiary of Xiaomi, begins to have a very complete catalog of connected watches dedicated to sport. The T-Rex model is a little apart, standing out with several military certifications supposed to ensure its foolproof strength. But is this enough in the face of the fierce competition that reigns at this price point?
- Foolproof resistance
- Very easy to use interface
- Quality sports monitoring
- Very good autonomy
- Good quality AMOLED screen
- Lack of functionalities
- No SPO2 sensor
- Some hiccups in GPS
- Proprietary bracelets
- Badly translated application
Every year, we witness the birth of at least two or three new Amazfit smartwatches. A frantic pace of release for this brand that is still young, but which seems to want to establish itself in the market for connected objects.
The T-Rex wants to be as imposing as the prehistoric animal from which it takes its name. A marketing choice that comes out of the ruts, reinforced connected watches are not legion in the mid-range. It remains to be seen if the rest is up to the task, as the 2018 Verge model turned out to be rather mixed in our previous test.
Marketed at 159 €, the Amazfit T-Rex must also face serious competitors such as the Huawei Watch GT2e or the Polar Ignite which are also aimed at assiduous athletes. The confrontation will be tough!
Amazfit T-Rex: technical specifications
Myself, owner of the Chinese brand’s watches, I must admit that the latest productions are often very close to each other in terms of technical characteristics. The T-Rex stands out, however, with its hardened shell designed to endure the harshest conditions.
As for the characteristics, they are very classic as you can see below:
Écran tactile AMOLED 1.3” – 360 x 360 px – Gorilla Glass 3
Heart rate sensor
GPS and GLONASS
Waterproof 5 ATM
Certification MIL-STD 810G
390 mAh batteries
Dimensions: 47.7 x 47.7 x 13.5 mm for 58 grams
Android based home OS
We remain in the standard of current sports connected watches. The Amazfit T-Rex however makes concessions on the functionalities: no Wi-Fi, no NFC, no SPO2 sensor, no internal storage for music, no microphone, proprietary bracelets… For the same price, the Huawei Watch GT2e is much more complete. Even the old Stratos from 2018 is fuller.
The manufacturer made drastic compromises to maintain the best possible value for money. But what we lose in functionality, we gain in resistance, the T-Rex being very robust. A choice that ultimately seems relevant in a world where the slightest shock endangers the proper functioning of our trusty smartwatches.
Compatibility level, the Chinese reinforced watch can work with smartphones running Android 5.0 and iOS 10 or more. For this test, we went on a Xiaomi Pocophone F1 running Android 10.

Design: an imposing but light watch
As often with reinforced models, the design is massive. The T-Rex is thus very beefy, being no less than 13.5 mm thick. With its mucho macho look, it will not suit all wrists …
However, it would be a shame to stop at that, the beautiful proving to be as light as its more classic competitors. Once on the wrist, you hardly feel it. On the other hand, its imposing size makes it quite unpleasant to wear at night.
On the left, the Stratos and on the right its little sister the T-Rex.
The case is made of polymer materials. It is surrounded by four metal buttons allowing to navigate within – almost – the entire interface without using the touch screen. The set is particularly elegant, at least if we like the impressive looks of this style.
It is at the level of the bracelet that the first disappointment occurs. Here, no universal attachment. The silicone strap – very flexible and light, a treat! – is fixed on a proprietary system. If it breaks, it will be very hard to change it. It is also impossible to favor one of the many bracelets offered by the brand… The T-Rex is therefore set apart, all its sisters possessing universal bracelets.
On the back of the watch, we discover a rather poor plastic shell. It’s quite disappointing, it is a little too cheap compared to the rest of the case. It houses the diodes for the heart rate sensor as well as the magnetic pads for the charging dock.
Very comfortable despite its overweight, the T-Rex seems built to last. We nevertheless feel the concessions made to keep an attractive price.
Screen: pretty but not at the top
Amazfit now diligently uses AMOLED technology, much more efficient than the reflective IPS of the Stratos to name but a few.
The T-Rex therefore uses a good quality AMOLED panel. The definition of 360 x 360 px is more than sufficient for such a connected watch. We do not distinguish excessive pixelation or even blur on the smallest characters.
The Asian tocante also has an ambient light sensor. The latter works quite well. But strangely, it does not lower the brightness to full during the night. The screen is then too bright. Conversely, even at maximum, the slab lacks punch in direct sunlight. It’s readable, but we have seen better on the Amazfit GTS or the Samsung Galaxy Watch which remains a real reference at the present time.
If necessary, an Always On Display mode is integrated. It offers two dials: one digital and one analog. They display the minimum vital, namely the time, the battery, the date and the number of steps. Too bad we can’t find the same dials as when the watch is on, but this is often the case on mid-range tocantes …
Still in its “reinforced watch” perspective, Amazfit provides its screen with Gorilla Glass 3 treatment. This should prevent scratches from appearing too quickly. In addition, the recess of the touch screen within the box prevents it from being directly exposed in the event of a fall on a flat surface.
Operating system: heavily modified Android
Like many of its competitors, Amazfit uses a home interface. Although based on Android, it has nothing to do with WearOS, the system for connected watches from Google.
For the T-Rex, the Xiaomi subsidiary is changing a lot of things in the operation of its interface. To be honest, the more time goes by, the more Amazfit gets to the point … It’s not as light in terms of software as the Polar Ignite, but it is quite close to it.
From now on, navigation between the various dials is done from top to bottom and more from right to left. As always, the main screen is the one dedicated to the time. The T-Rex offers two basic watchfaces, one digital and one analog. Twenty more can be downloaded from the app, but only one dial is registered on the watch at a time. A small regression knowing that on the previous watches of the brand we could store several.
By sliding down, you access the settings panel. It takes the basic shortcuts:
Energy saving mode
Do Not Disturb Mode
We also see the weather forecast, the battery level and the date in US format. And no, after all these years, European users still do not have access to data in the format of their region …
Always sliding up or down, you arrive on the dial dedicated to the heart rate. It displays your current calculated pace every minute and intensity zone. By pressing it, you access the graph of the readings for the day, as well as the percentage spent in each zone: light, intensive, aerobic, anaerobic and VO2Max. We get to the point without having to open the application.
The last dial shows your data for the day, in particular the number of steps. It also gives you an estimate of the distance traveled and calories burned. With a press, you can also access a graph giving a general idea of the progress over the current week. Don’t expect something very detailed, you have to use the app for that.
Connected watch requires, we have a few utility applications accessible with a swipe to the left. There is a jumble of a compass, an alarm, a stopwatch or even the weather forecast. Nothing very exciting, if necessary you can remove from the application the apps that are of no use to you. It should also be noted that the weather part, although it is quite complete, is still as capricious as on the brand’s previous productions.
Further parameters are also accessible in the list. It is through them that you can adjust the screen switch-on time, activate AoD mode or choose which application to launch with the button at the top right. It is clear that the parameters proposed have been reduced this year. Amazfit seems to want to simplify the use of its watches as much as possible. It must be said that the lack of Wi-Fi or music storage quickly limits uses. Even pre-designed training programs are taking their reverence …
To finish this roundup, let’s review the notification system. Nothing new on this side, we are sticking to something very basic. You can technically display any type of notification on the watch, whether it’s text messages, emails, or whatever. But under no circumstances will you be able to reply with pre-programmed messages or even reply with a hypothetical virtual keyboard. The T-Rex does like all Amazfit watches: it just serves to display notifications, period.
And the buttons in all of this? They can replace the touchscreen in almost all cases. Those to the left of the box scroll the screens from top to bottom. The other two are used to navigate forward or backward in the menus. A long press on the button at the top right activates the shortcut to your favorite application, programmed by default for launching an activity. In use, the touch screen is faster and more precise. In addition, it is not possible to open the list of applications through the buttons. However, we imagine that in bad weather conditions such as in pouring rain, these physical buttons must be practical to navigate within the interface without too much tearing of hair.
To conclude, the change in look of the Amazfit home interface also brings a change in philosophy. It seems that the Asian brand is always aiming for more simplicity. In absolute terms, it works well, the T-Rex is very easy to use. But we have more the impression of having a big activity tracker on the wrist than a real connected watch packed with functionality. It’s quite a shame …
