Amazfit - T-Rex 3

"Honestly there are SO many expensive options out there that do NOTHING, go for mid tier options like these 2 since stuff like this strikes a balance between price and features. 1) [The Amazfit one](https://quancoconline.com/dp-B0DHZDCF6WI) this one’s my top pick if you want REALLY GOOD battery life (27+ days), reliable fitness tracking, proper waterproofing, offline maps, and even AI voice control. Like, it does everything you actually need without turning into a second phone but it does not have google play store or third-party apps so if you’re into installing spotify or messaging apps on your watch, this ain’t it. 2) Galaxy watch6 is sleek, very smooth if you’re on a samsung phone, and probably the best looking out of the bunch. The fitness tracking’s good, and notifications are seamless but battery life isn’t great usually around 1–1.5 days tops, so you’ll need to charge it almost daily."

I love Amazfit. I have the T-Rex and T-Rex 3, the 3 gets about 14-18 days of battery even with GPS on.

I just bought the Amazfit T Rex 3 and love it! Lots of bang for your buck!!

How small? Mine is 5.9” and I wear a T-Rex 3 and Balance 2. Yes they are large on my wrist but I love a chunky watch. Of the two, Balance 2 is definitely better for less movement on wrist during a workout (which translates to more reliable HRM data).

I tend to wear my watches about 3 finger width behind my wrist bone. With the TRex 3’s default strap on the tightest hole that’s mostly okay but I do use an external HRM during workouts. If I swap in a different strap (similar in style to the Apple sport band with all the holes in it) I can get the device pretty securely in place and have no issues. With the Balance 2 (using the red strap, I haven’t tried the black one) I have zero issues. If either watch were *any* bigger it would be a problem though. They do look massive on my arm, but I like that style. If you’re not sure, the slightly smaller Active 2 might be a safer bet. Feature and sensor wise it’s almost the same. It doesn’t have multi-band GPS, but neither does my Apple Watch 10 and it doesn’t great with GPS accuracy. Sometimes the specs aren’t the whole story.

I have the T-Rex 3 and it's a fantastic watch for navigation. I just done a 3 day hiking and camping trip over a stretch of 40 miles and it never faltered once. It has a great battery also, it does run down after a day if you are using hi detail tracking and have navigation on for most of the day , but if you have a battery pack it charges quickly and doesn't use much charge from the battery pack

The Amazfit T Rex 3 is a steal for the price and features. They also just released a Pro model which has on board mapping and other features typically reserved for expensive garmin models. Battery life is amazing and GPS accuracy has been great for me in Colorado.

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.

I have amazfit T. rex 3 and it’s accurate. Wait for the $200 sale or reach out to customer service to see if they have a coupon.

Get the Amazfit T-rex 3 It's less than a 3rd the price and is as good or better than Garmin

I use amazfit t-Rex 3. Great watch. Paired with my hammerhead computer, stava and all of my other apps when I start a ride. I don’t like using the heart rate around the chest. I’m not a pro or anything, just a chad riding :). So metrics might be off a bit but it’s good enough for me.

I bought a T-Rex 3 last year and got the ring with it at a huge discount. I bought the Pro recently because of the upgrades that came with it and I am very happy. The flashlight for me is huge, and the calling features added.

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. 🤷‍♂️

T-Rex 3 is more than OK. TR3Pro's improvements are not so significant for your case. The only reason I prefer it is the Titanium bezel (I'm a fool for that metal!) and the crazy screen brightness. Keep in mind that T-Rex's screen brightness is also truly great..

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.

I’ve had my Garmin Fenix 8 51mm since it was released. It’s a great watch but overkill for a starter looking to get into using a turkey high end tool. I started with the amazfit t-Rex 2 then the t-Rex 3. At the t-Rex 3 price point it does almost everything the Fenix 8 does at 1000 dollars less. But if you’re looking to go with a watch long term, the Fenix is the end game and hard to beat once all the bugs are worked out of the software. ( theyvare still working though some pretty major software glitches like the screen and watch resetting when starting a hike…

Very valid point, can’t recall if my t-Rex 3 had anything besides snorkeling which I did use a few times. Not much value there for true diving! Lol… Just hope they don’t disable it again in a future beta release when he needs it. I do love my Fenix 8 regardless l. When it’s working it’s awesome but when it’s resetting itself multiple times on hikes I’m not familiar with, like here in Scotland and England, it infuriates me! Lol

I had a Garmin Forerunner 245 and was very happy with it. A first I dived into all the metrics, but then I discovered they are really only at best estimates, at worst plain wrong. In the end I just use it for time, GPS and Heart Rate, and ignore all Garmins opaque algorithms for the likes of VO2Max, Training Readiness, Sleep scores etc. Then my Garmin Forerunner started un-pairing from my Samsung A34 despite everything being on the latest software. Its now pretty unusable. So I looked for a Garmin replacement and was shocked at the prices. Garmin have basically priced me out. I ended up buying an Amazfit T-Rex 3 for around around 220 USD in a sale. GPS and HR are just as accurate as Garmin, and it has a much smoother and intuitive interface. Amazfit Zepp app is not better than Garmin Connect, but then again its not really worse, just different in terms of things that do not work, or are buggy. Both companies really need to improve their software. So I would say its worth looking around at alternatives to Garmin especially if you are on a budget.

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)

I have an Instinct 1 solar 45mm and bought the Trex3. It's huge compared to the instinct. Also, it's shape and odd strap made it feel even bigger. I changed out the strap with nylon, which helped a bit, but still It's very big. It's very bright so you'll like that. Heart rate sensor during exercise is a bit better, but not much. The OS is a bit laggy when using touch. The app is better than Garmin IMO, but I don't care about all the metrics, so I don't know how they compare. It certainly syncs faster than Garmin. The zepp flow voice thing is very bad. I removed it from the widgets. I sent mine back despite getting it on sale for $170 because I found I didn't like the AMOLED at all and the shape made it look comically big. Some parts of the OS are clunky, like vibration. As long as the shape and size would work for you, it's a much better watch than the Instinct if you like AMOLED.

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.

Instinct. Forerunner 265 Fenix E Or go against the grain and buy an Amazfit T-Rex 3 which is laughably good for the price.

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 

Amazfit T-Rex 3, that's what I use at least, you also get offline maps on it so you can import your route and follow it through the watch without the need to pull out your phone all the time. You get all the metrics that you might need plus helpful tools to help with the hike. It's basically a Garmin on a budget. Garmins are great but it's hard to justify the price tag for me as a casual hiker. I guess if you really wanna go that route you can get a Garmin Instinct 2 for not a lot of money but you don't get maps, just a trail line of your path to follow with no context, still enough for many people though so you might be happy with that.

Went from a garmin fenix to an amazfit t rex 3. Almost a month battery life and great workout tracking and maps.

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.

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

who said it was bad? ZERO issues with the 3 pro, and also had ZERO issues with the 3 when I had it

I have the Instinct 2S and the battery life could barely make a day of tracking so I had to charge every night in camp. The Amazfit Trex3 made it 2 days easily before I would top it off

Amazfit Trex 2 or 3 is amazing for physical activities, and should be around the price of the squares or a bit above.

Amazfit Trex 3 is a good and cost effective option for you. It is also rugged for those rough trainings. You can sync Zepp App with Apple Health. Or else a discounted/refurbed Fenix/Epix Pro but they are much more expensive.

If you are using a watch that is older than 3 years its very likely (outside of apple watch, garmin, coros, polar and suunto) that it doesn't come close to matching current models accuracy levels - especially as most brands (wear os / apple / garmin / coros / polar / suunto / fitbit / huawei / amazfit) update the sensor and gps chipset every 2-3 years (if not more frequently) and there have been significant improvements all around. For example current garmins are either using the elevate 4 or elevate 5 HR sensor (from health 24/7 perspecive virtually immaterial difference in results, but from an activity perspective especially around strength and cycling their is a more marked improvement - plus the elevate 5 sensors include ECG and baseline temp monitoring) however the elevate 4 was a significant jump from the elevate 3 sensor (4 veritcal led lights) which was an even bigger jump from the sensor prior to that (3 leds in a triangular shape). Huge jumps and leaps have been made in sleep tracking too, and for most its way more accurate than it used to be - though don't get me wrong it still can be fooled (i.e. sitting/lying and being super inactive (i.e. reading / watching tv) and its possible the watch can potentially record that as sleep. Garmin Forerunner 165 - its on special on Garmin sales at just under $200. (or could look to see what deals you can find for the instinct 2 or vivoactive 5). These are all running pretty much garmin's latest version of sleep tracking which is way better at determining sleep duration (I find start time is rock solid and seldom gets fooled - if it does at the worst it records it as light sleep so doesn't really impaact recovery at all -as would be giving you that as recovery anyway and the recharge rate from light compared to resting is so simliar I haven't noticed a difference in recharge rate; and wake time is rock solid as long as using morning report - cause as soon as you access morning report it switches off sleep - so if you wake up and want to go back to sleep don't access morning report - the morning report front screen includes time so no need to access it until you want to be up and about). The sleep tracking algorithms are from firstbeat and includes the use of accelerometer, HR and HRV compared to the older garmin sleep tracking which per my understanding was accerlerometer based. You could also look at anything from amazift (stick to bip 6, active 2, t-rex3 or balance - as all running most current version of their software and alogorithms); Huawei including Fit 3 is worth a look; and could consider anything from coros, suunto (just released the run which should be around the $200 mark) and polar. And you could also look at fitbit charge 6, sense 2 or vera. There is also xiaomi but their HR isn't as good as the others... But worth noting the accuracy of optical HR is still impacted by skin tone, body comp, hair, tats, weight & size of watch, how you wear it and if doing an activity the activity type - and until you use it there is no way to know if it will be accurate for you or not. However for most people most of the sensors of the brands I have mentioned tend to do a good job re accuracy for 24/7 health metrics and steady state activities (walking, steady running etc).

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.

For me, any smartwatch that can’t last at least a week on a single charge just isn’t worth it. My T-Rex 3 easily lasts at least two weeks, even with regular GPS use for my runs.

Get the TREX 3, the FR55 is nothing compared to the Trex you will enjoy the map display.

I have an Amazfit trex 3, best bang for buck and it has dedicated freediving modes

Trex 3 is a badass watch

Amazfit Trex 3 for sure, such a sick watch tested for the cold, offline GPS maps, waterproof, shock proof, 10-15 day battery life, so much more cool stuff. I have the active 2 the baby version of it and it’s amazing, would highly recommend and probably the cheapest of all the watches on here and it even has an AI assistant

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)

Depending on what features we are talking about, Garmin Venu 3 and Amazfit (Balance, TRex) both are delivering strong battery.

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.
