Amazfit GTR 2 Review: Sleep & Heart Rate Test (I wanted to like it...)

[@Biocentric]

Can you please repeat the Amazfit GTR 2 heart rate test with the stress monitoring turned off? Many say that will make it accurate.

[@aminek244]

What about the GTR 2 New Version accuracy please ? Someone tested it ? Thanks

[@ggianne]

Don't know if you have already done but would be nice a table like in Google spreadsheet, updated after each test, with devices names and score for each sensor in the columns (heart, SPO2, ECG, Blood Pressure, exc..)

[@pd3022]

Hi Thanks for the great review. I have the GTR2e and GTS2e and I agree with your review. Yesterday however they released 1.3.18.02 and the heartrate detection seems a lot better(the changelog also states this fact). Would you mind testing the 2e with this firmware update? Thanks!

[@ScinDBad]

Yes, that would be great. Maybe the doc just can publish the new results in a blog so He doesn't need to film another video

I'm thinking of buying the gtr 2. So far, how has your experience with all of the tracking of gts 2e and gts 2e been?

[@pd3022]

@@trojjo I will be honest with you. I have since moved to a garmin venu2 watch, as the gtr2e/gts2e devices were not accurate at all. The venu 2 has been way more accurate. And I would not recommend spending money on the Amazfit devices.

[@wjofre1]

Was waiting for this one, thank you! I was hoping the accuracy wasn't THIS BAD. What a bummer, because the watch looks really attractive.

[@TheQuantifiedScientist]

Happy to help!

[@Mnkmnkmnk]

I was really considering the gts2e or the GTS 2 mini, because they look great with their amoled screens and long battery life. But not anymore. Really sucks because there is really no comparable activity tracker.

Agreed. Would be incredible if you could run your detailed review on the OnePlus watch. Super interested!

[@alfo5322]

Hello, I sincerely loved the video, it takes a lot of effort and dedication, you have earned my subscription. I have the GTR2 and I was able to compare it to a medical grade EKG, and the measurement was very good in anaerobic ranges, but at VO2 max the measurement is about 6BPM below the real one. I assume it is a software problem that has already been fixed. Greetings from Argentina

[@trojjo]

I'm thinking of buying the gtr 2. So far, how has your experience with all of its tracking been?

[@acarrizosa08]

I'm looking forward to your analysis of the Amazfit Neo. The GTR 2 uses a Huami-made sensor, but the Neo uses an older sensor (which does not include SP02, VO2max or HRV). I wonder whether the inaccuracies are caused by the new sensor in the GTR 2 or whether inaccuracies are also present in the Neo. If problems in one and not the other, then probably a sensor issue, but if problems in both then it could be either the sensor or the software causing problems.

[@Dirman_panembahan]

Hi , have u found any video that talk about amazfit neo accuracy? Could you please give the link, thanks in advance.

Data (and facts) is king! A pity because it's a good looking watch. Thanks Rob!!!

[@J0nas1.07]

Can you do a heart rate test for the amazfit bip u pro? That would be very nice

We want a video about the amazfit GTS 2!!!

[@c.m.7692]

The GTS 2, GTS 2 mini, BIP u pro, the zepp e models and probably a lot more models all have the same sensor, BioTracker 2, so you ~~should expect the same results~~ [Actually it seams like there's a lot of variance between models and between same models but deferent updates. Biotracker2 is definitely capable of an accurate tracking see WesKnows jul. 9th video]. It could, and should, get better through updates though as zepp health gathers more data from users.

[@TheElipsus]

Awesome test as always, indeed it's a bummer that the tracking is so bad for such a nice looking device !

[@richie7091]

Hi Rob, great video as always. A shame to see such poor results from the GTR2. Do you have any plans to look at Coros products? Keep you the great work!

[@c.m.7692]

Hey Rob! How much of the failure of this watch could you attribute to the software or the lack of data that Zepp Health has compared to competition? Or in other words, how much could Amazfit or Zepp get out of the BioTracker 2 given time and data? Or lastly if you'd prefer to talk in general terms: how much do you think activity tracking devices are limited by their hardware VS by their software... Besten Dank.

[@Aveiro17]

Thanks for your videos, awesome to see real data. Was thinking of picking this one up (the cheaper "e" version) , but found your channel yesterday, and this video is perfectly timed. Would be interesting to see the xiaomi mi watch and the oneplus watch. (and the ones you mentioned at the end) Subscribed!

I can confirm. I have a gtr 2 unit and the heart accuracy is really shameful. Regarding sleep tracking I couldn't make any comparison because I don't have any other unit to compare with but I already had a hard suspicion about how bad it performs.

[@riverthames4408]

This is amazing information that, as a normal user, I never would have found out if I hadn't watched this video. You mentioned that Apple Watch 6 is your recommendation for heart rate tracking, with the Fitbits taking over sleep tracking. Would you be able to recommend a smart watch that sits in the middle and does both well enough to be useful? Thanks in advance

[@marcokoehler5020]

I bought this watch as a present for myself at Christmas since the cheap amazfit BIP S did quite well. I couldn't believe that it didn't work for me at all. I thought I must have a faulty unit since why should the more expensive gtr2 be a lot worse than the 60 Euro BIP S? Well I returned it and seeing this video it seems like it's just garbage. Such a shame, could have been a nice watch. The watch that I'm most interested now is the oneplus watch. I'm using the garmin vivomove luxe at the moment and it's 'ok', but something with more than 3 days Battery life that looks good and works well enough would be a reason to switch. Since amazfit is out of the game, apple and samsung don't even get 3 days - the oneplus watch could be the one.

[@TheAmol297]

Love these videos. They are so detailed! Can you do a review of Samsung Active 2?

[@Pr4gM4t1]

I wish this video was posted before I bought one (GTS 2 mini /mid Feb). The HR tracking is really bad, especially for activities with a lot movement of the arms, i tried a lot of combinations, sometimes work fine, but in many opportunities did not. Usually loses HR tracking, from 140-150 fall to 70-80. Sometimes never go over 80-90. And today the screen is dead, so no refund for me. Excellent reviews and videos.

[@Inzanti]

You ordered a great set of devices! Looking to the videos. I'm rather happy with my HB6's sleep tracking but have no idea if the stages are close to accurate 😂 Sleep score usually reflects well though.

[@Lieyre]

I just have to thank you for creating that channel and that content. I do admit, at first I was kind of mad at you, since I really wanted to like this watch too and you ruined it for me! I wanted to buy OnePlus Watch but the reviews started rolling in about how inaccurate it was that I got interested at how accurate other smartwatches are and there is no other channel that really measures it. All the OnePlus reviews said to "Just get Amazfit GTR 2 instead" and your review made me realise it might be as bad or worse. But thank you for adding your own comparisons and suggestions in, will buy Huawei GT2Pro now!

[@dimalex8]

[@nameberry220]

Please do the Amazfit Band 5! And also test sleep tracking with each available application, Zepp (official), Notify for Amazfit and Sleep as Android. The last two seem much more accurate!

[@bernardtan1]

Notify for Amazfit isn't more accurate than Zepp. It's way too much off. Can't even record or detect naps.

[@invisibileism]

Thanks a lot for this much awaited review, too bad the watch was such a disappointment. I guess when you saw the sleep and heart rate results you decided that there was no point in testing the step counting :) I really liked this watch or the GTS2 but considered these results and what other users reported about the GPS and steps counting accuracy it seems there is absolutely no point.

Same experience here.. I bought it for 7k not at all worth. No calendar, calculator even quick reply. There is only incoming...no outgoing. Frankly speaking these are some of the basic features which a smart watch must have otherwise it would be called as dump watch. I'm regretting my purchase. 😒

[@castertroy2534]

Hi! Would really really appreciate it if you could also do the Amazfit GTS 2 Mini. Ive researched about it for 2 months and decided to buy it, it's currently on iys way now. Other resources I've seen have said it was pretty good. However this GTR 2 review is making me think twice. And I'm mainly going to use it for sleep tracking since my work is during the graveyard shift

[@jacobreubenaglipa5669]

Maybe you should get fitbit for assurance of the performance.

[@lorandabos3120]

I'm curious, how likely is it that software/firmware updates will improve these measurements, is that something that typically happens with smart devices? I just ordered a gtr 2e mainly for the looks/other functions, but it would be nice to have tracking perfom at least decently. Great video as always!

[@tzeimet]

It's slightly better with the update. In this case I don't think it's the fault of the sensor, but rather the algorithm trying to filter out the true HR and any bad measurements. The watch essentially does not register HR which it thinks are anomalous e.g. if you're heart rate jumps up quickly, the watch is likely to register a lower value because the algorithm thinks it's a bad measurement, so sometimes it will register 80 instead of 160 bpm.

[@danielbum912]

When HR trackers are this adamantly stuck at heart rates in the 75-100 BPM region while cycling I always suspect that they pick up your pedalling cadence over the heart rate. As in, pedalling causes your whole body to wobble slightly, up into the wrists, where the optical HR sensor picks up sine-like changes in brightness from periodical flexion to support your wobbling upper body... Or maybe I'm reading too much into it and it's just really bad & mostly guessing :)

[@Mnkmnkmnk]

Very nice to see such rigor for a youtube video.

[@cityplanner3063]

Thank you for this information. That means most recent Amazfit watch’s all have bad tracking as they all use the same sensor, even the cheaper Bip U
