Amazfit - T-Rex 3

used to have stratos 3 and then t rex. I switched to huawei because of the heart rate sensor. It was tragic. Especially in cycling it didn't measure at all.Do we know if it has improved on the trex 3?

For those curious. I posted a follow up video comparing T-Rex 3 directly to Fenix 8 as it was highly requested in the comments of the first video. I tried to be as objective as possible but there's some opinion sprinkled in there. Hopefully you find it helpful. TLDR: The Fenix 8 is 4x more expensive but also has a lot of advantages for more advanced users. The T-Rex 3 is still awesome at $279 and hard to beat at that price. Hope that helps.

As mentioned, I was shocked by how well the HR sensor was on this unit. But it seems like I'm one of only a few people who have been testing it so take my results with a grain of salt. Yes, I did multiple tests and they all looked good but I still can't rule out luck! Stay tuned for follow up content on the CTS channel.

Yes, it even displays the icon for the app (for most). Some apps I've noticed aren't displayed but most of the big ones are and you can toggle on/off which ones you want to see.

The strap adapters are plastic but they feel like the same plastic used on the watch body which is a pretty robust material. Even the Garmin's use plastic for the band attachment points so it's nothing I'd worry about. Then again, it would have been nice if they just used standard bands but... you can't win em all!

To be honest Vo2 Max, Sleep tracking, Stress tracking and other features should not be a deal breaker because they are pretty inaccurate on most watches and shouldn't be taken too seriously. Good battery, accurate GPS and decent heart rate should be sufficient for any self motivated person working on their fitness. This watch is a win in my book and my wife and I are thinking of retiring our Garmins in favor of Amazfit (Balance for the wife, T-Rex 3 for me) And yes, the price is quite compelling in today's economy!

Everyone and their nan is going to say Coros and Garmin, but hear me out, look in to Amazfit, i've had a lot of watches for diving, surfing, running, hiking and had the introductory £50 GPS watches from amazfit from about 6 years ago and now on the Cheetah and could not be happier, does everything and more for a fraction of the price of Garmin and now they've just released the T-Rex3 which is comparable to the Garmin Fenix 8 but costs a third of the price.

I'm coming from a Fenix3 from 2016 and looking forward to receiving the Trex-3 as a replacement. The Fenix 3 battery only last about 14 hours on GPS before needing charge as its getting up there in age. I know I can just replace the battery but I also want some new technology. The Fenix 3 overreads GPS distances about 5-10% when compared to a couple handhelds that I use as a reference.

I got it for a month now and I am really enjoying it. Just sent some update suggestion on the sports I use to practice (rowing). Even the xiaomi simple bands have moth accurate stats used by rowers, like stroke count, stroke rate and pace in the 500m/min format, not simple speed like if you were riding a bike… it’s an amazing watch, but it also has great room for improvement.

It works, but not with the stats we are used to

No, it does not even have a Stroke count, I sent the suggestion to the Amazfit support, they answered me saying that it’s going to pass to suggestion to the development team. Let’s see if they add these basic features for rowers in an upcoming update

I really don’t get why some watches have SPM, cont and pace as rowers use, others don’t. I had a MiBand7 that had these stuff, and the xiaomi’s and Amazfit OS and app interface are really similar. I still hope they fix that in an upcoming firmware update.

Geeeeeeeez!!! And yes this is the only thing missing on T. rex 3... The only reason I went for it was the buttons position, you can not use the balance with gym gloves otherwise they will destroy the crown...

Does T-Rex 3 get the Morning Report? Does it also get the same reply features the Balance just got?

I ordered the T-Rex 3 first and then ordered the Balance a week later. In between the T-Rex order and the balance order I got an automated message from FedEx saying that there was going to be duties due when they order delivered. I actually only had to pay duties on one watch and that was the T-Rex 3 but my duties ended up being $164 Canadian, on top of the cost of the watch which I got for $198.99 USD ($278 CAD). I didn't have to pay duties on the Balance. 🤷‍♂️

I picked up a Forerunner 265 to replace my TREX Pro and I returned it after 4 days, no comparison for the price, my Trex pro was way superior and I just got the Trex 3 which is way more than I was expecting for less the price of the Forerunner. I had my Trex PRo for over 2 years, never had a problem, now I don't know what I will do with it.

I have used almost all the Apple Watch models, early Samsung models, and Garmin (Forerunner 255) for years. As an athlete and smart/fitness watch enthusiast, its an incredible watch. I sold my one-year-old Garmin FRS 255 and, for that money, got a brand new T-Rex 3. I have never been happier. It is miles ahead of FR 255 in all aspects, workout detection, responsiveness, and functionality. It's amazing for $200. I mainly care about the metrics, but it was almost spot on on the first day of sleep. My Garmin never detected workouts even though the function was on, I noticed how Garmin was crappy by using T-rex. One thing I miss from Garmin is the Body Battery, Morning Update, and a more intuitive stress display. I turned on the Morning Report on my T-Rex, but it doesn't show anything when I wake up. Also, the Body battery is supposed to be "readiness" but the readiness doesn't change throughout the day. Readiness score needs some tweaks ASAP, it basically doesn't change, no matter the quality of your sleep, like it does say kinda "your sleep quality was okayish, take it easy today, but here is your 87 readiness score" which is absurd to say the least. The stress display on the watch is also not as intuitive as in Garmin, and it has a lot of gaps throughout the day, especially during the most stressful moments. I wish Amazfit added a Body battery kinda feature to look at throughout the day, because it was kinda fun to look at while I was using Garmin. When I used Apple watch, I never looked at it, even when I was bored, because it didn't have any info on the watch to look at, but on Garmin, Body Battery made me interested in looking at it and engage with it. Switching to T-rex 3 kinda rewinded me to Apple Watch days because the stress metric is not as much intuitive in the app and lack of body battery. PSA: Have some mercy on yourself and get a nylon band if you are using a T rex 3. Its out-of-box rubber band is quite low quality and gave me insane rashes in a few hours of wearing it. Nylon bands are very comfortable, light, you don't even feel the watch and its good for your skin. I bought a few from Aliexpress for $1.5. Give a salary raise to anyone who designed this watch because how badass it looks got me curious about the company in the first place, and won me over to switch to Amazfit. I don’t usually buy AI subscriptions, but bought Zepp Aura for $15 a year just to support the company and rooting for Amazfit cause the quality, heart rate accuracy, and design are top notch and making quality products, **most importantly -** **at a low cost**. I am buying Bip 6 for my mom and wife, as its HR accuracy is up there with Apple Watches (which are #1 in the wearable market in HR accuracy).

Don't buy an overpriced Garmin. T-rex 3 design is not for everyone because its rugged and masculine and if you don't mind the design, T-rex 3 is waaay better than $350-$1000 Garmin. I don't think its better than $1300 Fenix 8, but it can compete with it, there are reviews on youtube from credible youtubers comparing these 2. The fact that they are comparing and not finding too much of a gap between $1300 and $200 watches is more than enough to tell you how good T-rex 3 is.

T-Rex 3 is great! I'm using it for almost half a year. Anyway, sorry to say, buy I lost hope in any serious, big updates for Amazfit watches: [https://www.reddit.com/r/amazfit/comments/1khsh4r/amazfit\_trex\_3\_and\_active\_2\_serious\_bugs\_still](https://www.reddit.com/r/amazfit/comments/1khsh4r/amazfit_trex_3_and_active_2_serious_bugs_still) IDK, maybe they don't have enough resources. They are fixing smaller stuff like: [https://www.reddit.com/r/amazfit/comments/1kkjl0t/amazfit\_trex\_update\_3751](https://www.reddit.com/r/amazfit/comments/1kkjl0t/amazfit_trex_update_3751)

Nabbed mine right at midnight before bed. So stoked and glad the HRM is much more accurate. Super excited for it as I have an Apple Watch Series 6 and my god the battery suuuuuuucks. Always charging it feels like. Now I can get accurate health data and not constantly be charging it.

Hello I recently purchased the t-rex 3 to replace my fenix 5 and I loved it! But I am a cyclist and vo2 max is important to see the progress of my fitness . It is in the plan to add Vo2 max for cycling?

sure Garmins or something like Amazfit Trex3 or Huawei GT3 are not full blown smart watches, it all comes down to what you need .. I prefer to have more battery life without some features. 10 days is ok , 7 minimum, 2-3 weeks is optimal with functions like notifications, phone calls, media controls, weather, voice assistant control, calendar, fitness and health, maps/navigation and some others I dont need.

Hi guys, Thought I'd give my thoughts on the T-rex 3, just a quick review and not a deep dive. For reference my current watch is a fenix 6 (standard not pro etc). I received the watch yesterday from Amazon for £259 after a £20 discount code which they had on the item (amazfit have a 10% one). First impressions were excellent, screen is in fact very bright and very nice to use easily matching my wifes apple watch, big win over the fenix 6. Setting up was again easy with QR codes linking to the app, all a very painless affair. I watched chase the summit's review on this and picked up a few things such as the heart rate tracker being set to 5 minutes etc and moved this down to every minute just to get as much info coming into the watch as possible. It's worth noting that when doing so the battery really did tank (it warns you of this when you change it) to the point I reverted back as it had a severe impact on the battery life. Exercise time: Most of my riding is done on a peloton at home noting the British weather although I do run, cycle and mountain bike. Again this worked well with the watch using the indoor ride function the heart was picked up by the peloton straight away and seemed accurate as to what I would expect the bpm to be on a 45 minute ride. Once completed this sync'd fine to the watch and to strava, shortly after this came the deciding factor with the watch. The ride showed on the zepp app and indeed had recorded correctly along with a training load similar to what I would expect to see from my fenix however as expected there was no metrics for power / distance etc. I wasn't aware at the time of purchase that you can't manually add any of this information to the recorded ride or make any changes to what the watch has recorded (would appreciate this so the zepp app shows at least the miles I've covered even if manually entered). After a little more digging it turns out that amazfit does not calculate any sort of cycling Vo2 max, it does however record running Vo2. After some thought I found this to be a bigger deal than initially expected, although not a deal breaker for some I appreciate the graphs presented by garmin which show how this has changed over time and gives me a good amount of motivation when it comes to fitness that there is some trend which is increasing. This combined with a lack of some further metrics which garmin is able to provide got me to decide to return the watch and stick with the fenix. The difference between both watches are minimal and the amazfit does indeed work well, it strikes me as a watch something between an apple / samsung watch and a more dedicated offering from garmin / suunto etc. Should anyone be looking for a watch which will provide a good amount of health and fitness information along with most smartphone / smartwatch features then I think this would be a great recommendation and would defo say pull the trigger on it as I doubt you will be disappointed. It's a real shame as I would have happily kept this watch however for my use case it is missing some of the more detailed metrics, lack of peloton integration (this may apply to zwift etc as well, might need to check however) and lack of Vo2 max means it isn't able to record and provide me with the information I'm after as I'm training for several events next year. I've seen a few posts on this watch so just wanted to give my thoughts, as an FYI there is a script that you can use to post peloton to garmin so it uses the peloton ride metrics and takes it into garmins bits and bobs to calculate everything but nothing similar for this watch. If you're on the fence and use case doesn't sit like mine 100% recommend: + Good looking (in a fenix / large sport watch way) Very comfy especially stock strap Very slick to use, no lagg Maps work well, imported from komoot and worked no worries Easy icons Set up is simple Battery life seems good (watch the HR sensor) and should easy head towards a week - 10 days. Screen is brilliant Sleep detection seemed reasonably accurate HR monitor worked well inc using on a third party device Value is off the scale - Some metrics are there some are not, depends on what you need Can't alter / add anything to an activity Only takes mp3, not the end of the world but for this kind of watch shame there's no spotify Changes from stock set up can hurt battery life substantially No Vo2 max for cycling Thanks all, hope this might help anyone on the fence!

Thanks for your thoughts. I picked up the AmazFit T Rex 3 with the Helios Ring with FSA money I had left for the year. Amazon UA made this process super simple with no issues. The ability to switch between ring and watch for different activities as well as support for external HR sensors is good  So far, metrics with the TRex 3 are consistent for HR, HRV, and resting heart rate. Sleep, especially wake times seems a little low. I have only had the watch and ring a week or so, but the readiness score seems off. Too high and too low. Maybe after 30 days and a good baseline that will improve.

I have recently bought the trex 3 and it had 17 updates to down load and I have to say it has exceeded my expectations, swimming is perfect for pool laps front crawl and breast stroke are accurate I've not tried open water swimming yet  In the gym it's brilliant and you can adjust the weight and reps on the go and it's good at rep count and very accurate and even tells you what muscles you use not always 100 percent accurate in determining what muscles but I'd say 80 percent and it's a cool feature, Sleep for me is also very accurate  Steps is also very accurate and no ghost steps  I've not tried running or hiking yet so I won't comment  I don't get people saying sleep or fitness tracker not good or accurate, I'm doing fitness all my life not a professional but certainly a person who constantly trains and I just can't fault the watch so far  If anyone is reading this and thinking of getting one I bet you will not be disappointed A couple of years ago I went for a 5km walk with a friend who was wearing a Garmin forerunner 265, at the time I was wearing a bip 3 and the step count was of my 27 steps just saying 

I already replaced the rubber strap with the adapters and am using an aftermarket "ultra fit" style nylon band. Looks pretty decent even with the adapters to me and I'm picky how some something looks. The adapters look to be the same material as the Trex 3 and seem like good quality adapters. Also you will need your own 22mm pins for the adapters to use a strap as I didnt see any pins coming with the adapters. I had my own already. Also idk where to help people with this but I used Enduro 2 glass screen protectors and it fits perfect. I have a Enduro 2, Amazfit Balance and now the Trex 3 and they all can use the same size glass screen protectors. 

I tend to put metal bands on my watches and I think that's where adapter will ruin it the look. The distance away from the watch with a black adapter is too great for me to pull off a nice metal watch style. I have a metal band on my balance and looks very nice. But as I place the band up to the Trex 3 with adapter I can tell it wouldn't look right. The Trex 3 is definitely a rubber or nylon style watch. So balance as my dress look and the trex for sporty look. 

I switched from the Garmin Enduro2 51mm sapphire solar to the T-Rex3. There is nothing on the Garmin I miss except the powerful flashlight. But the display flashlight on the Amazfit is not bat at 2000nits. I will probably sell the Enduro2.

I am thrilled with it, coming from an Enduro2 51mm SS. The display is a huge step up from the MIP. It isn't sapphire, true, but Gorilla Glass 3 isn't bad and the raised bezel is protective too. The GPS tracking and HR perform just as my Enduro2 does, even in difficult locations that trip up my Edge520.

Have no idea why you posted this question in this sub. Amazfit TRex 3.

It's all good. Seriously just bought my son his second amazfit watch. Does everything all the expensive watches do at a fraction of the cost. They just started carrying them at bestbuy. The one I linked is a rugged version that is supposed to be protected.

No, get the T-Rex 3 or ultra if you are looking to upgrade from the T-Rex 2

No, get the T-Rex 3 or ultra if you are looking to upgrade from the T-Rex 2

u/Amazfit-Bryce love to see the support team reply here, show that the company care :) I am also moving from the Garmin ecosystem to Amazfit T-Rex 3... super excited to see how it hold up vs my Epix Gen 2 (which I love but I like to test/change to new wearable haha). Anyway, mybe you have the answer to my question, or maybe u/Resident_Amphibian96 you can also. is the T-rex 3 able to share on iOS (Iphone), HRV readings to apple healthKit ? What about workouts? Are all the informations there in apple health (route, HR etc.) I can't seem to see the information online. IMO, having the HRV reading pushed to Apple HealthKit would be a HUGE differentiator compare to competition for more serious athlete, as you can then use other apps that do really well at calculating recovery, readiness etc... Apples like Athlytics for example. Not a lot of wearable export the HRV readings to Apple Healthkit (Garmin doesn't, I don't think Oura or Whoops do also) but I am pretty sure it is within the scope of Healthkit API. So if anyone has an idea about this OR if it's not the case right now, Amazfit team, that would be my request to you :D I assure you that this is a differenciator to some people who are training more seriously as it allow us to keep using our recovery app. It also makes it much easier to move from Apple watch, as apple watch obviosuly do share HRV readings with healthkit

Just got my T-rex 3 ! Love it so far. As thoguth, HRV doesn't sync to Apple Health. Once you guys do the sync, i 100% will buy the Helio Ring as well :) Already got an update for the T-Rex, so it looks like the release cycle is pretty great, so this is good news, excited to see the improvements over time

I would agree with you on that. I had Garmin fenixes for years, Garmin Epix pro, Apple Watch Ultra, amazfit trex 3 (current watch) and just got a whoop. Imo for weightlifting nothing beats the Apple Watch (ultra or not doesn’t matter) due to all the different apps available. I was using Hevy and the ability to do a live workout between the watch and the phone at the same time was dope: want to change exercice or do more complex changes during your sessions, you simply edit the workout on the phone. But if you want to do just a 5lbs increment on your lift, you can do it from the watch directly live. Only thing I am eager to test with whoop, which is a important part my decision to do the free trial for a month, is to see muscle strain and how it work in tandem with the cardio based strain. Whoop is the only wearable to do that ( but it seems you can do it with Bevel now)

BRO the trex3 voice assistant is actually chatgpt 4o!! you can ask it way more than adjust watch settings! you can use it like gpt!! ask it questions, ask it for recipes, ask it for dietary advice etc etc honestly i think thats an absolute killer feature

This is my third T-Rex watch. I had the first, the second and now I have the third generation.  Everything is fine. BUT! You forgot to transfer the most important function from the second generation to the third one — auto pause in workouts. It was so useful in Outdoor cycling. You don't need to pause it and unpause every time you stop for a snack or for a phone call. Please fix it. It's just few you extra lines in code. You have already done it in the second generation of T-Rex watch.

this is the main point of buying Amazfit products! had my trex 3 for 3 months now, and like it so much more than my garmin epix pro, and, like someone said, even if it burns out, I can buy 2 replacements or more, and still save money over the overpriced garmin stuff

Yes :) https://preview.redd.it/4chpngcc1end1.png?width=1079&format=pjpg&auto=webp&s=5d2b6dc64196661d862904248a1123ebe68b8bd7

I have the amazfit Trex and I feel like it does everything I’d want. Had it for at least 3 years. Charge it every couple of weeks.

Could be fake reviews. Amazfit (by Xiaomi) are legit and very cheap as well.
