Amazfit T-Rex Professional evaluate: Removed from extinct, however struggling to evolve

“Shorter battery life than promised and the identical design because the previous model dampen enthusiasm for the Amazfit T-Rex Professional, however an inexpensive value, dependable software program, and robust exercise monitoring cease it going extinct.”

Complete exercise monitoring

Dependable, straightforward to make use of software program

Battery life is not as marketed

No design alterations over earlier mannequin

Amazfit has been making a reputation for itself with a spread of competitively priced, enticing, and easy-to-use smartwatches such because the GTR 2, and now it’s again with the Amazfit T-Rex Professional. It’s a follow-up of types to the T-Rex from early 2020, however it’s not the main evolutionary leap we’d wish to see after a yr of ready.

Repeating the identical designs again and again (the Amazfit GT sequence all look mainly the identical too) isn’t what we count on as of late, and whereas it might assist maintain the value down, it doesn’t actually encourage a lot curiosity or pleasure. Let’s take a better have a look at the T-Rex Professional to seek out out if we must always ignore the dearth of creativeness, or if Amazfit wants some inspiration.


Did you see the Amazfit T-Rex? Good, as a result of the T-Rex Professional seems to be virtually an identical. One slight change has made a distinction to the impression the watch leaves, and that’s the completely different bezel remedy. The T-Rex’s bezel on my evaluate pattern was black plastic and appeared low cost and nasty. The T-Rex Professional’s bezel is a contrasting grey shade and has had a “metal-spraying” impact added, and it does have a barely classier model than the previous model.

In any other case, the form, dimension, and design are the identical. The steel buttons have the identical texture, the watches weigh mainly the identical at 59 grams, the Professional’s 22mm silicone rubber strap has extra texture however the identical design, and the 1.Three-inch AMOLED display screen is similar dimension and has the identical 360 x 360-pixel decision. They’re the identical.

The T-Rex Professional is designed for toughness, with resistance to excessive and low temperatures, humidity, salt, and shock. It has handed 15 completely different assessments, in comparison with the T-Rex’s 12 assessments, and has a 10ATM water resistance ranking, up from 5ATM on the previous T-Rex. What all this implies is the Amazfit T-Rex Professional is a bit like a Casio G-Shock watch, full with button guards and the oversize 13.5mm thick polycarbonate case, plus some G-Shock-esque watch faces. It’s additionally very similar to the Honor Watch GS Professional, however it doesn’t look or really feel as costly.

Do I hate it? No. The strap is comfy and has loads of adjustment for all wrist sizes (though the 48mm case isn’t actually for small wrists in any respect). As somebody who actually likes G-Shock watches, I don’t fully object to the styling decisions, however many will see it as huge, ugly, and ungainly. It definitely lacks the goes-with-everything class of the GTR 2.

What I actually object to is the T-Rex Professional is the T-Rex simply with a unique shade bezel, and even essentially the most optimistic will wrestle to name it “ brand-new.” I respect repeating the identical design retains improvement prices down, and due to this fact the ultimate value low, however to repeat this advert nauseam doesn’t generate any pleasure, and that’s a significant issue within the aggressive world of wearables.

Health and exercise options

Now I’ve had a moan concerning the design, certainly we come to what makes the T-Rex Professional an improve over the T-Rex, and maybe see what makes it Professional. Whereas the hardware does comprise essentially the most important upgrades over the previous smartwatch, they’re hardly large alterations. The guts charge sensor has been upgraded to Amazfit’s BioTracker 2 PPG optical sensor, and the watch now has a Three-axis gyroscope to go together with the Three-axis accelerometer, and a barometer too.

Andy Boxall/Digital Developments

The upgraded BioTracker 2 sensor additionally takes Sp02 blood oxygen readings, and Amazfit boasts of the watch supporting 100 completely different exercise modes, however this seems to be a software program replace characteristic additionally discovered on the GTR 2e slightly than particular to the T-Rex Professional. The sensor upgrades have allowed Amazfit to include some wonderful new health monitoring software program options, that are surprisingly in-depth on the watch, and within the accompanying Zepp app.

Monitoring a 30-minute train session returns the anticipated time elapsed, calorie burn, and common coronary heart charge, however you additionally get extra particular knowledge like cadence, common stride, velocity, elevation modifications, and coronary heart charge zones too. When you’re achieved it offers a really helpful restoration time together with VO2 Max knowledge, and knowledge sourced utilizing FirstBeat’s algorithms. It’s complete and principally straightforward to grasp, and I like that it may possibly all be seen on the watch with out visiting the app in your cellphone.

The FirstBeat coaching impact knowledge does spotlight a standard health tracker drawback. It offers graphs exhibiting your Cardio Coaching Impact and Anaerobic Coaching Impact, alongside along with your Coaching Load, which is all very attention-grabbing, however there’s little or no data on what I’m alleged to do with the information or tips on how to interpret it correctly. Compelled to seek for extra data, I used to be led to FirstBeat’s personal web site, however discovered I used to be actually none the wiser after studying what was there.

It’s possible this knowledge can be extra useful, or maybe simply extra acquainted, to athletes or these devoted to sure sports activities, however for informal use, it goes too deep with out sufficient clarification. In any other case, the activity-related upgrades on the T-Rex Professional have improved it over the previous mannequin, however they would want to accompany different enhancements to make it a extremely fascinating improve.

Utilizing the T-Rex Professional

The T-Rex Professional makes use of Amazfit’s RTOS software program and never Google’s Put on OS. It’s fast to reply, has clean scrolling for essentially the most half, and the menu system is logically laid out. It really works by display screen faucets and swipes, plus the very wise bodily buttons. There are 4, labeled Up, Down, Again, and Choose. They do precisely what you count on, and are giant sufficient to deal with gloved fingers.

It’s extra dependable with notifications than Put on OS, though the textual content is primary and there’s no solution to reply or work together with messages on the watch. There’s an efficient always-on display screen for every of the watch faces, I like the excellent climate reviews and I’m positive climbers will respect the barometric knowledge too, plus it controls music on my cellphone too. Better of all, I haven’t skilled any instability or software program issues.

Coronary heart charge monitoring appears to be correct, with the outcomes given by the T-Rex Professional being according to the numbers on the Apple Watch Sequence 6. It’s not as quick because the Apple Watch to measure your coronary heart charge although. It additionally takes longer to ship an Sp02 blood oxygen studying, however principally returned the identical consequence because the Apple Watch Sequence 6, however this data isn’t very useful to anybody who isn’t midway up a mountain and anxious about altitude illness.

I in contrast the T-Rex Professional to the Apple Watch on a 30-minute stroll, the place it matched the common coronary heart charge, however there was an roughly 200 step rely discrepancy, with the T-Rex counting fewer steps than the Apple Watch. It estimated a better calorie burn too. Whereas neither is more likely to be precisely proper, the Apple Watch is acknowledged as one of the crucial correct for coronary heart charge and step rely knowledge, however the T-Rex Professional’s distinction isn’t drastic.

The Zepp app is similar as it’s on the Amazfit GTR 2 and GTR 2e, and works with each Android and iOS. It collates your exercise knowledge, allows you to customise the watch’s features, choose apps to ship notifications, and carry out software program updates. It has remained solidly linked all through my evaluate interval. General, the Amazfit T-Rex Professional’s software program, and in flip the possession expertise, is excellent.


If the software program is nice, what concerning the battery? It’s not so good, and undoubtedly doesn’t stay as much as Amazfit’s guarantees, not less than in case you intend to make use of the options it incorporates. The corporate says the 390mAh battery — the identical because the one within the T-Rex, unsurprisingly — will final for 18 days with typical use, and 9 days with heavy use. With the always-on display screen lively, coronary heart charge and stress monitoring, two 30-minute exercises tracked, and normal notifications alerts, the T-Rex Professional’s battery lasted for six days. I don’t take into account this to be heavy use, as I’ve not fired up GPS, or tracked hours of exercises.

Andy Boxall/Digital Developments

I may flip off the always-on display screen and coronary heart charge monitoring, which might prolong the battery life (though I’d be very stunned if it instantly was capable of attain 18 days), however what’s the purpose? You purchase the watch to make use of the options, not faux like they don’t exist. Amazfit’s claims of such lengthy battery life are, in my expertise on the T-Rex Professional and different Amazfit wearables, extremely optimistic.

Value and availability

The Amazfit T-Rex Professional prices $180 or 139 British kilos, and is in the stores by Amazfit’s personal web site. It’s lined by a one-year guarantee and comes with a 30-day trial interval too.

Our take

The whole lack of creativeness put into the T-Rex Professional’s design is irritating. There is no such thing as a want for it to look precisely the identical because the earlier mannequin launched over a yr in the past, particularly when the unique was hardly a design traditional, and the hardware upgrades listed here are solely modest. It comes throughout as a slightly lazy replace, from an organization tired of attracting new patrons. When you didn’t just like the T-Rex’s seems to be — and anecdotally, many individuals I spoke to didn’t — you gained’t just like the T-Rex Professional both.

Andy Boxall/Digital Developments

There may be nothing in any respect to say, “oh, it’s the brand new T-Rex Professional” on the skin and it’s a disgrace, because the software program, efficiency, and exercise monitoring is excellent. In some ways, the T-Rex Professional gives a superior normal expertise to a Put on OS smartwatch, and the low value makes it very tempting. Fashion apart, the primary unfavourable level right here is the battery life. Six days of what I take into account normal use isn’t dangerous, however it doesn’t meet Amazfit’s claims, or match smartwatches just like the Huawei Watch GT2 Professional, or most health trackers both.

Maybe you’re not so caught up within the design facet as I’m and are after a fairly priced, out of doors activity-focused smartwatch. During which case, the T-Rex Professional will do the whole lot you need, simply with extra visits to the charger than Amazfit tells you.

Is there a greater different?

The T-Rex Professional’s value could be very aggressive. For instance, the Honor Watch GS Professional is 250 British kilos, and has very comparable performance, though the supplies used give it a better class really feel. Our really helpful smartwatches, with out the toughness, all price much more. The Apple Watch SE begins at $279, the Samsung Galaxy Watch Three at $330, and the Mobvoi Ticwatch Professional Three at $300.

When you aren’t apprehensive concerning the powerful exterior, Amazfit’s GTR 2e has many of the similar options inside a extra trendy, slimmer case and prices simply $140. If the smartwatch options are much less of a priority, a health tracker might swimsuit you higher. When you just like the G-Shock model seems to be, simply get a G-Shock watch. The G-Shock Transfer GBD-H1000 is $400 and has intensive exercise monitoring options, plus it’s correctly powerful.

Lastly, the T-Rex can nonetheless be discovered on the market on-line, and it prices about $140 however will be discovered for much less. Sure, the hardware additions are welcome, however in case you simply need a powerful smartwatch and never spend an excessive amount of doing so, it’s in any other case very comparable.

How lengthy will it final?

The T-Rex Professional’s toughness means it’ll face up to appreciable punishment, so if you will put on it in harsh environments, it shouldn’t break on the first signal of water or mud. Offered Amazfit continues to assist the Zepp app and the software program on the watch, it would final for a few years.

Nevertheless I do suppose the design will date shortly, and the polycarbonate case will possible choose up scuffs and scratches over time in case you do use it as supposed, that means it’s possible you’ll really feel the necessity to substitute it sooner.

Do you have to purchase it?

Sure, the T-Rex Professional could also be similar to the previous mannequin, however it’s nonetheless a well-priced, feature-rich smartwatch.
