46:52 Conclusions
The Huawei Watch GT4 comes in two sizes 46mm and 41mm, where the 46mm version is clearly aimed more at men and the 41mm version at women. The 46mm version comes in 4 colors: black, brown, green and gray, with different types of straps for each, though the green one might not release everywhere. The 41mm version comes in 3 colors: white, light gold and silver. In terms of design, the thing that stands out most is the octagonal bezel of the 46mm version. Personally I am not the biggest fan, but this is totally subjective of course. What I do like is the design of the 41mm version and the way the screen lays flush with the watch bezel.
In terms of heart rate tracking, the Huawei Watch GT 4 now comes with the newer TruSeen 5.5+ algorithm, whereas the GT3 launched with 5.0+. It is not publicly known what Huawei changed exactly about the algorithm, but they say that they use Artificial Intelligence algorithms to train an individualized model based on your historical data, that should improve the accuracy of the heart rate readings even under difficult conditions. They mention that it should for instance be better now during running for instance, and they also claim that the sensor should have improved accuracy in low-temperature environments, as well as faster blood oxygen readings and enhanced sleep reading accuracy. The GT4 can also take continuous measurements of your heart rate, oxygen saturation and stress levels throughout the day. Although I cannot test this, the GT4 has menstrual cycle management; version 3.0 keeps track of menstruation cycles and tries to estimate the ovulation date by analyzing things like your heart rate during sleep, body temperature, and breathing rate.
The GT4 uses version 3.0 of the TruSleep algorithm, which Huawei says has better sleep tracking accuracy; specifically Huawei says they estimate your sleep stages based on body movement, heart rate and HRV. Additionally, the GT4 now adds a new Sleep Breathing awareness feature that could help identify symptoms of Sleep Apnea. Similar to one of the biggest brands in the smartwatch world, the Huawei Watch GT4 also shows your daily activity in a ringed format. These rings are now slightly changed. - วิทยาศาสตร์และเทคโนโลยี

Will you be doing xiaomi watch 2 pro after it releases on the 26th? It has all the features and I just want to know if it's accurate enough to be a good buy for me
Another great review, really wish other companies could come close to matching apple's accuracy for sleep tracking as the eco system lock-in and battery life are not ideal for the apple watch ultra.
Can you do the ticwatch pro 5 please?
Hello,
Can You test the Huawei Watch D?
I think the results for health tracking are much better than other.
I'm torn between buying the Huawei GT4 and the Amazfit Balance.
Would you be able to test the heart rate accuracy of the Amazfit Balance, please?
TH-cam algorithm is not doing you justice at all...
This channel is a gem...
Definitely deserves much more subs
The reason must be the fact that he exposes a lot of expensive watches that sell the dream but that are actually garbage in terme of measures
@@bigdonger6949 well said 👍
Big companies don't like that at all
i agree
That heartrate test was fantastic, the fact its better than the Garmin fenix 7 pro and epix 2 pro, is opening my eyes lol
Always very informative & educational Rob. Can't thank you enough for all your work 😁

Hi Rob. I was eagerly waiting for your next review. They belong to the most intersting and helpful stuff on YT. Enjoying it all the time. If I may utter a wish then please do the Huawei Watch Fit Special Edition and the RingConn ring tracker. Thanx for your efforts as always.
Thanks Rob. I'm really appreciate what you have done
Just found your channel today, quite nice and detailed reviews, I'm liking!
As for the weight lifting results, from what you said the happen mostly when doing pecs and triceps - those exercises are usually the ones where you exert much higher force on your hands (and consequently on your forearms), and that's probably why there's worse HR detection during those.
Rob, you are a real treasure👊
Thanks a lot! 😊
@@TheQuantifiedScientistPlease review the Huawei Watch D 😋
Hello, thank you for your high-quality content and your time. I'm curious, are you planning to test the new Apple Watch 9 and Ultra 2? And when can we expect the video?
Once again you're doing an amazing job! Thanks a lot again!!!
What? Watches were announced yesterday and you've already made review! What a legend!
I just discovered your channel and it's absolutely great. I watched this after the pixel watch review and notice the numbers all seem to be different, and much better than the original review. Was there some kind of update or did you reassess them for any reason?
Quality content bro 👌👌👌
Loving this ❤
Side note: I'm quite impressed on how Huawei Watch Fit 2 remains unbeaten as one of the most accurate HR monitors according to your tests. I've bought one last year after watching your analysis - and I'm still very satisfied with it.
Is it good for running?
Same, it's been great and very good for running.
Me too, It is the best
Fit 2 is solid. I’ve had it for about 8 months and it tracks my workouts and calorie burn very well. My only complaint is that a few times out of the month my sleep tracking is a little wonky but mostly good overall. SpO2 is pretty good as well.
does you guys have issue with huawei health not sending the heart rate data to strava? i'm on iOS so health sync app is not an option :(
Liked and subscribed. Thanks Rob. Cheers from México.
Congrats for the good work!
Hey, Rob, is there somewhere where we can compare the results of each one of the wearable you reviewed in whatever category we want so we can find out which one fits us the most?
do it yourself, spoonfeeder.
Thanks so much for testing these tech so thoroughly!!! (And not just repeating what can be read online)
@TheQuantifiedScientist
Nice job! I hope you can help me with an interest question, and I believe there are not much solid information about it around tbe internet.
There is any problem using fitness trackers/smartwatches/smartbands on the inner side of your wrist (palm side)? I mean, how bad is it (if bad at all) to the accuracy of the device?
Do you have a word on this issue? Maybe you can consider doing a video testing it, would be great!
Hi, huge admirer of your channel, love the rigorous testing for wearables. Do you have a review for the TicWatch pro 5 coming up? I have the watch, and would like to know how accurate the sleep tracking is.
Many thanks for these videos!! Very, very useful!
Amazing channel, Rob! Your smartwatch accuracy are awesome and so much more valuable than the usual pseudo-tests in other review videos. I especially like that you perform the GPS tests in my hometown Vienna, so I get a fairly good impression what those smartwatches are capable of.
One small improvement suggestion: could you maybe underpin the GPS test with some quantitative data? E.g. length of cycled distance reported by smartwatch vs actual length as on Google Maps? That would allow you to rank the smartwatches on gps accuracy as well.
Hey rob great video! Do you know if the GT4 will get non invasive Blood Glucose update like the Huawei Watch 4 and 4 pro will?
Awesome video as always
Great video as always! :) I was really hoping you would review the Huawei Watch 4 Pro. Do you have plans to test these watches? Many thanks
I'm sure it will more or less the same. Good HR and mediocre sleep just like this and previous devices. They use the same tech after all
The best channel for smart sport watch ! many thanks from France.
When will you be receiving the new Withings Scan Watch 2? Nice video as always!
Thank you Rop, as usual 5 star review, are you going to do any review on Garmim venue3?
Great review, as always.
Thank you for all the contents :)
Meanwhile, are you testing also the new Garmin Venu 3? It seems to be a big improvement in garmin products
Garmin is bad. ONLY name.
Thank you. This video actually convinced me to get a Gt4
Thanks for the review. What warch would you recommend for sleep apnea detecting?
Great review, thank you. Have you also tested the non GT versions? Is there a difference?
Great video as always.
I have a question. Are you also planning to test Huawei Watch 4 and 4pro? Do you think the results on those would be different or pretty similar as they probably use same algorithms?
Keep up the great work 😊
Watch 4 and Pro don't are good. Maybe worse than GT4.
@@MarcoPolo82 that's why I would like to see the scientific test on them as well 😉
Based on what you state this?@@MarcoPolo82
@@markQ08 me too @The Quantified Scientist will be a test on huawei watch 4 ?
@MarcoPolo82
Have you tried it and tested it?
Because the sensor is not the same
Excellent review. Thank you.
Great objective scientific review. I bought Huawei Watch Fit 2 because of your objective reviews. Apple should adapt the battery technology of Huawei to its smart watches, and Huawei should adapt the accuracy of Apple smart watches. Its a win-win for consumers to have this kind of competition of large companies to push themselves to create a much better products.👍
Rob, good work on the detailed research. really appreciate it. I haven't seen all your videos, so I am not sure, if you have addressed these questions previously: does the result vary on how snug the watch is around the wrist? What is the variability from person to person? Is it better to test with a similar band type across watches. I haven't used an Apple watch, does it provide consistent tightness around the wrist irrespective of wrist size?
The rectangular shape of the Apple watches makes them less prone to movement that might tilt the sensors, I think thats why they pickup good results.
I have Apple watch and couple of Huawei watches and the position of the Huawei on the wrist is always tilted, if you tight it too much it records wrong details.
I use a stainless steel straps on all my watches so it always the same tension across all models.
Hi, based on all your total tests of every watch of any brand or generation which watch would you get to count your steps?
Will definitely be waiting eagerly for your Apple Watch 9 and Ultra 2 reviews
Great analysis. Is there any testing for swimming?
Totally helpful review..super! Thanks!
So quick! Big thanks.
You're welcome! 😊
I adore your scientific approach. As always, perfect. Waiting for Apple Watch Seried 9 review.
Hi Rob ! Any chance you would be testing the Huawei watch 4 ? A bunch of us are looking forward to it. Cheers
Love your reviews! Can you please test Amazfit Balance? It is the Amazfit GTR 5, but with a new name, and I am not sure which one to buy, I like Amazfit more, but based on the older reviews of yours, the Huaweis are generally better, however they use a completely new heart rate sensor now.
The beautiful green GT4 will be my next watch ,great review
Great review as usual! I'm happy to see you're expanding on the test and information for the watches reviewed.
After the disappointing sleep measurement, do you believe that the Google Pixel Watch is the best all around watch for Android? I saw you corrected the outdoor cycling for the Pixel watch in your newest videos.
Personally, I think the Pixel Watch is the best android smartwatch when it comes to health tracking. It's just a shame that the battery is not very good and many data are locked behind a paywall
How could it be best when it's battery is always dead?
@@bojantenja I meant in terms of health tracking and features, especially as it will receive updates until 2025. I'm trying to decide between 1 and 2. There are many reddit threads where people agree that while the battery is bad, it lasts 24 and even up to 48hrs. Some compare it to the apple watch battery life and notice no difference, but I suppose it's varies greatly depending on the use case.
Hi! I have to check on that change in outdoor cycling (don't have the data here). I collect new data sometimes, but I don't think I changed anything for the pixel watch, and the data should still come from the same source. If there was a change, not sure what happened. The data loading is mostly automated at this point, and I just indicate a folder and date range.
Always great to watch yours. Look forward to having review on Cheetah! Cheers
Very nice video! But I have some questions about the heart rate measurement results. From the line graphs of each test, it can be seen that the heart rate data of gt4 seems to have a few seconds of delay compared to the reference device. This delay will significantly affect the correlation coefficient R, but in the actual use process, this delay has little impact on the experience. Have you tried to eliminate this delay by shifting the data and then calculating the correlation coefficient R? The cause of this delay is also unclear. I noticed the trough at 21:07 in the heart rate graph at 45:40 in the video. Gt4 clearly detected this trough earlier, rather than the usual delay, which is also very strange.
Delay has plenty of affect if you put limiter. Couple of seconds faster notification might safe your life
@@trym2121 it really wont lol. maybe if it was delayed by upwards of 15 seconds and even then its not an apple watch so it wont notify you if it detects anything unusual instantly so youd feel it before the watch does
Thank you! Can the alarm to be set to the time close to light or REM sleep so that I be waked not exactly at 4:00 AM, but in a range 4:00-4:20 when the sleeping mode is the best for awaking?
great review, thanks!
Thank you for such a detailed video. Please make one testing Garmin Venue 3 as well.
I even emailed him asking him for that review lol
Yes, that will come. I am wearing one at the moment :-)
@@TheQuantifiedScientist please do a sleep test, It would be very helpful and much appreciated! The new venu 3 has nap detection and it is something that might be better than fitbit (because all the previous garmins were not as good as fitbit) thank you!
@TheQuantifiedScientist Wow, nice. I hope venue 3 does well in sleep tracking, I am looking forward to it. Thank you, for testing it. We really appreciate it.
I was hoping for Venu 3 as well. BTW I have Huawei Watch 4 as well as the O2 ring and can confirm all of the results from the video. HR tracking is barely better than Garmin's, SPO2 is basically fake as well as the sleep tracking. HRV is missing, stress is very very questionable....I wonder why I bought it at all. It has LTE and great watch faces and that's all...
Hey Rob, do you have plans reviewing the Garmin Venu 3? The price is 50% higher then when the Venu 2 came out and i wanna know if the higher price is worth it
Great reviews! Will keep my Huawei GT Runner for now!
I see no value in upgrading. I also stick to my runner. HR monitor is also slightly better than this gt 4 🤔
Hello Rob....Any ETA. on when you expect to have a Apple Watch series 9 review ready for release?? 🙂
Thx for the review!! I think ill wait for gt4 pro
Awesome Review 👍
Thx from Munich 😉
Great video. A question: Huawei Watch GT4 or Amazfit Balance, and why?
Could you test the activity auto detect accuracy feature as well esp the cycling autodetect by different watches
Love the channel, and waiting like crazy for sleep tracking test for Venu 3 and forerunner 265 as im on to decide which is for me, and sleep tracking is one of most important thing for me and the watches are pretty similiar. Especialy intersted as garmin introduce new sleep tracking/coach and nap tracking in venu 3, im VERY curious about these two.
Is there any way that You will test these watches?
Cheers!
In overall performance, which watch would you recommend?(Going into consideration apple and garmin products too)
Please make the accuracy test of galaxy watch 4 after all updates as it's available for less price now. Thank you 😊
Hello thank you for very good review, great job 😉. Do you think Huawei Watch 4 will perform similiar like GT4? Because I havent find rewiew of Watch 4. And comparing to Samsung Watch 5 Pro is GPS tracking much better or only a bit? Thanks
Love your work! Thanks, Does it display HRV readings? Greetz
Anybody?
Best professional review ever seen. Thank you ser
@The Quantified Scientist will be a test on huawei watch 4 ?
does it measure blood pressure? thank you for the video very helpful
Are you going to review the amazfit balance? I'm about to buy but waiting for your review
great work! what about the Huawei watch 4 series ?
Based on all your testing, what are the best Garmin devices? Are they as good all-rounders compared to the Pixel watch?
Thankyou for the review! Could you also please review Redmi watch 3 active 🙏. Probably the cheapest smartwatch reviewed in this channel.
Hey Rob, are you planning on reviewing the Huawei Ultimate?
Hi. Tha ks for yoir work. I would like to ask when you will make a test about huawei watch 4 pro? Thanks again
Hi I've a suggestion/request, on GPS test please could you showw the dfference between the mesaure of the distance, to better understand if the watch could be used to run, and collect the correct PACE (time for chilometer)...this is for all the review...💪💪💪💪💪
Please consider reviewing the "Honor watch 4" . Honor seems to have the same hardware as Huawei watches but now have a dedicated app on both ios and android + none of the issues that huawei faces in the US.
Thank you!
Well done ROB, keep it up
How does the gt 4 gps test compare to the forerunner 255. Because I’m trying to choose between these 2 watches for running
Really impressive, comprehensive, most of all, scientific review. Im a fan now, sir!
Does the GT4 have the same heart rate sensor as the GT3pro? Thanks!
Amazing, thanks!
Glad you like it! 😊
Hey Rob, Is there a internal storage on the Watch? Can we put songs on it? Thank you!
Will you test the Huawei Watch 4 and/or Pro as well?
You're the real scientist bro 🔥🔥🔥🔥
Are you going to do an updated review for the fenix 7 pro, garmins new sensor?
Any idea on when the Scanwatch 2 analysis will be out 👀 I really hope its better, cus the battery life is unbeatable!
I too am waiting for this review!
Would love to hear about the HUAWEI Watch FIT Special Edition too, pretty recent availability for me and I'm not sure between that and the band 8. Amazing videos as always, thank you!
So if you want a watch, with balance quality for all the tracking (heart rate, sleep tracking, gps, etc), not the one that just great in heart rate but not good inn sleep tracking (for instance), which one should i get? (except apple watch). Thanks
Hi, thank you very much for your service, can you tell me if it tracks football (soccer)?
Would like to have a look at Huaweii Fit Special Edition test. Would also like to see Mi Band 8 and Mi Band 8 Pro when Global Version come out
Me gustan mucho tus videos y debo confesar que después de haber visto varios. Solamente confío en ti en lo que se refiere a los smartwatches. Muchísimas gracias por tomarte el tiempo y esfuerzo de probar los dispositivos. Abrazos desde México. 🎉
Hi thanks for another great review. Have you ever considered comparing how much radio frequency radiation different devices emit and what (if any) possible implications this radiation may have on health
I totally support your question, radiation from watch is serious problem
Radiations from phones, watches, etc etc have literally 0 effects on health. You can chill.
What is the watch setting to allow the route plotting on Google maps?
Hi Rob, many thanks for your work, it has been really useful in not :) choosing my next Android watch! For Huawei GT4 however, despite the flaws in the device, one key feature will make me buy it if accurate, the CGM capability... do you plan to test it when available? Many thanks!
Ditto! This was a terrific video, and now I've subscribed. I, too, was hoping to get Rob's input on the Continuous Glucose Monitoring (CGM) feature, in order to decide whether to buy this watch.
Rob, is it possible to test these watches with a elestic watch band, like apple? That would guarantee the contact with the skin even when weight lifting. I know you are busy, but I think a test with different bands wouldn't take that much time and would eliminat another factor. Just a suggestion.
which one is better for sleep tracking and overall the gt4 or the samsung watch 6 classic
Between Huawei GT4 with Coros Pace 3 which you prefer to for Runner?
Great video. Although how about the GT 4 Pro ?
Gt3 pro or gt4 is better?
Thanks for the review
Oxegen saturation for other brand during situation where it is drop like when on plane it really needed
