It's great that you repeat tests on devices after updates. OMG, It's absurd that Samsung managed to worsen the watch accuracy after the update! It would be awesome if you retested on Mi Band 6 after the updates. A test on the new cheap redmi watch 2 lite would also be awesome. Congratulations on your excellent work! All TH-cam reviewers should consult your videos before reviewing on their channels.
Mi Band 6 is OK.. better than GW4 in my testing but still quite often has a fit and goes crazy on just a walk and says VO2 Max + 180HR when walking where really next to no effort is being used (easy to talk etc).... I've tried all different positions and band tightness changes. I gave up and got a Garmin instead and it's been perfect. Mi Band 6 is perfect otherwise but this HR bug I think is a sensor limitation as it only has one HR sensor, Garmin have two or more depending on the version.
Honor Band 6 also because from the day of the test and now occurred more than 5 updates.
@@LaurenceGough do u think all garmin are good? I'm thinking of buying Garmin lily
Literally the only youtube channel I am excited to new videos uploaded. Just what we needed!
I own a galaxy watch 4 and the only reason I am not getting an apple watch is due to the fact that I'd have to get an iPhone. Otherwise it would be a no brainer
That for the compliment Stefan!
The Galaxy Watch 4 has just received another major update where Samsung claims it has improved the heart rate sensor. Is it worth a third look perhaps?
Absolutely love all the data here, obviously the most detailed reviews of these devices. Would love to see this on a website so we can gorge over the data and do comparisons. It's really hard to decide which to pick.
Been addicted to watching these videos, very well made and easy to follow. Would love a ticwatch e3 video if possible. Thanks and subbed.
Thank you so much for testing it after the update. I'm disappointed in the results but super appreciative for your efforts 🙏🙏
One of the rare channels where the tests have actual value. Keep up the good work!
It might've been interesting to have a 3rd reference for the same workout tests (e.g Apple watch 7). That could help identify if polar had some bad readings potentially in some scenarios.
I have had my Watch 4 Classic for about 16 months now and unfortunately the heart rate monitor is still, after a number of big updates where Samsung claims to have improved it, quite bad. Same goes for SpO2 and sleep monitoring. I go for long walks at a brisk pace and I haven't had more than a few walks where the heart rate monitor doesn't stop working randomly, for a varying amount of time. It happens almost every time. I've tried a looser fit, a tighter fit, both wrists, different bands. I even got a replacement watch, but nothing works.
In some cases the heart rate monitoring stopped working altogether and wouldn't come back until I rebooted the watch. I like my Watch 4 Classic in other ways, but I will definitely not be getting another Samsung watch for a while. While a good smart watch for things like communication and navigation and phone calls and such, with a lot of apps, it's downright bad for monitoring pulse, blood oxygen and sleep.
Thank you for the update Rob
Thank you so much for the updated review.
Great job again appriciate, it is very important to keep the objectivity and follow the updates, because much people decide to buy a smart watch after watching your videos, by the way I am waiting a new current results for Garmin Venu 2, because you know black friday is upcoming I will by a watch, Thank you 🤗
Please do the Ticwatch pro 3 Ultra tests. So many people interested in this watch. And thanks a lot for your hard and detailed work 👍
Thank you so much Rob. Great job. 👍👍
Thanks James!
Really awesome! These are such great videos that do an update on the quality of previous watches. I know it's a lot of work, so thank you!
Annnnnd on another note... >< Is there any chance of doing an update on Withings Scanwatch?
Always very informative videos. I have seen many of your smart/fitness watches videos and it helped me to decide which smart watch to get based on how accurate they are. One favour I would ask, can you test the Coros Pace 2 watch please? It would be much appreciated to know how it performs on your full review tests. Thanks!
Thanks for testing this stuff.
Thanks for checking the update. I'll sending this watch back. Could you check the tic watch pro 3 ultra next?
Thanks for doing this retest! I think what people dont seem to get when they see graphs not aligning perfectly is that from my own testing the average HR and Max HR will align very closely between devices like Polar chest straps, Garmin running watches and the GW4. Day to day no one is comparing different graphs, just the end stats which are pretty accurate anyway, easily good enough to use as a fitness device on a smart watch.
Can I ask if you also found the average HR and max HR data was accurate between the devices regardless of what the graphs looked like?
Another great video. Happy Thanksgiving
Great video. Love your channel.
Thanks so much Paul!
Thanks fir the review.I think people now is waiting for the review of Tic Watch Pro Ultra GPS
Hi man, great review.
What's your top 3-5 health smart watches on the market in your opion? Cheers
Thanks a lot for your videos...do you know if the update also improved the SpO² sensor? After reviewing so many smartwatches, any recomendation on how to wear them correctly? Thx again
Great review! Can you do a video about the Tic watch 3 ultra?
great video. You should spent lots of time for doing so good and scientific tests. And what about sleep accuracy now?
Thanks for an update on the update. Please continue to do these tests.maybe samsung should be made aware of your test results.
I hope so.
I've been seeing some very strange results from just standing still and tracking with an exercise running, vs just the background tracking without exercise mode. There's a 10-20 bpm difference for some reason.
It's like because the watch is in exercise mode, it automatically adds more HR when there isn't or something
Thank you, Rob, for the update ! So sad to see Samsung struggling to get the HR good. I mean it's nowhere near to the Apple watch 6 and 7. Maybe you day, who knows :)
Great test, please do scientific test on ticwatch pro 3 ultra..
Samaung should pay attention to your videos. It's amazing that they release a new product with this big flaws! Is there a way we can tag samsung?
Great videos! Great reviews! Thanks for your work and time!
Would you recommend a Huawei watch fit over this for regular fitness tracking and simple smartwatch use? Idc about apps etc
Could you do a Huawei Watch 3 pro analysis, please? Thank you for your work so far!
Hi Rob, can you please test the biostrip?
I’d love to see you do a test of the new Citizen CZ. I was going to upgrade to galaxy watch 4 but after seeing your tests I’m glad I didn’t. I did however get a Scosche rhythm+ 2.0.
Think next time I upgrade my phone though, it may be back to apple simply as the watch sensors appear much better. After having a heart attack a few months ago, I’m watching my heart rate blood pressure and ecg a lot more closely now
Do you have any videos on the Garmin Tactix Delta solar. Just ordered that. Currently using gw4, also ordered oura ring 3. Want sleep and hr and pulse ox videos. It's similar to the fenix but has solar sapphire glass which us why u ordered that version
Hi when are you testing for the rest of the features. The updates got better only in HR or sleep too?
What about analysing Garmin Fenix 6? It would be great!! Thanks in advance!
Have you tried it now after the new wear os 3.2? Is there plans?
Would love to see a scientific review of the Apollo neuro.
Please can u do the ECG Comparison with medical grade equipment, if possible do test like ECG,BP on the patients 🔥🔥👍🏻👍🏻💯💯
BTW ur video on accuracy is DAMN COOL and to the Point.
Love from Mumbai,India 🇮🇳❤️
Thank you so much for these tests. They really provide valuble insight we don't recieve anywhere else.
If you have the opportunity. I would very much be interested in your review of the TicWatch E3.
I'm having a difficult time trying to find a smartwatch that also has accurate fitness tracking. The Venu 2 looks good, but lacks some key smartwatch features. The Galaxy watch is a great smartwatch, but suffers in fitness tracking.
Hi Jonathan, been there done that, I'd for sure recommend the Garmin watches, the HR sensor on them are leagues better than the GW4. Not only that but the battery life is many magnitudes better too, and no bugs!
bende sizinle aynı fikirdeyim garmin saat tasarımları çok kötü ve amoled ekran modeller arasında malesef yok çok ilkel hesapmakinesine benzer grafikleri var ekran tazeleme oranları çok kötü ve ekran geçişlerinde lag var bu yüzden istemiyorum satın almak fiyatlar çok yüksek sadece doğru veri gösterdiği söyleniyor en tutarlı markalardan biri olduğu için tercih ediliyor ama amoled bilinen markaların tüm saatleri neredeyse sensörleri hatalı ölçmekte doğru veriden yoksun. ayrıca bir çok markanın gögüs sensörü ile birlikte kullanımı yok sadece garmin ve polar markası destekliyor sanırım harici kalp sensörleri bende karar veremedim ne alacağıma
@@alimuharremturan581 Garmin MIP display offer far higher battery life, far better visibility in daylight and don't require a backlight for anything apart from pitch black. As for lag there is no lag compared to GW4. They also offer AMOLED models with just as good sensors if not better.
I am very grateful for your reviews and studies. They have been extremely valuable for me and I'm sure many others. I would love to see if Samsung has improved the sleep monitoring and the blood oxygen measurements. I currently own this watch but was planning on returning it due to its poor performance. I am hoping to change my mind.
Hi Rob, I'd advise to return it before your time is up! Samsung don't give a damn and you'll be stuck with it! There are many better watches on the market, although the GW4 classic does looks great it's not worth the compromises in performance, bugs and battery life.
@@LaurenceGough I did return it, no point in spending the money on something that doesn't provide meaningful data. Cheers!
You are the best
Thank you for following up, Rob! Hopefully Samsung will keep working on the algorithms to make them more accurate. Apple shows it's possible.
Garmin shows it's possible too, their sensors are amazing compared to this watch so for Android users it's a great option.
I respect the results he was able to get. Now my problem is the watch band as hard and non flexible they are the absolute worst why not switch to the same type of band you used on the series 7. Your a scientist correct? So by degree your smarter then I am plus you got all the gadgets to back you up correct? Now if loose fitting, bumps, shakes, etc… screw the results why use a band that makes the watch sit insecurely on your wrist. And there is no way you can tighten that band to secure it and I can back that data. I use mines all day unloading trucks, running, working out etc… with a sports band no problem with the in box bands just bad. I love that you have all the equipment and what you do but how correct are those results using the in box band that’s not secured properly.
Did you know any app the shows the percentage of the fc max? In my spinning classes they always ask about it, 70%, 82% OR so, but I can see this with this watch, thanks to anyone that can answer!
Hi! Hoping you could help me choose a smartwatch or fitness band/health band. I have undergone angioplasty last January this year, and I am now health conscious. I need a watch or a band that can detect HR, SPO2, and BP. budget is $400 or much better $300 below. I know that it cannot replace medical equipment's, but it will help in monitoring while I am on a daily living activity. Accuracy is of the essence. I am eyeing at Galaxy Active 2. Also, any recommendations will truly be appreciated. Thank you.
Which watch is better the Galaxy watch 4 or the Huawei watch gt2 pro
Hello how do you get the graph like this? Mine just shows the range every 30 minutes
Hey could you check Polar T34 it costs half of the Polar H10, but how much worse is it?
I was really hoping it would have gotten a lot better
We need a retest (yes, again) after One U.I 4.0 update because Samsung claims that they implent new HR measurement algorthm. Thank you!
Yes, I think it would be helpful. I noticed that my Galaxy Watch 4's treadmill accuracy has improved significantly since the most recent update. Hopefully other aspects have improved as well.
I hope so.
It didn't fix anything, not for me at least. I've had mine for almost 16 months now and it's still - after a number of big updates - borderline useless for heart monitoring, blood oxygen and sleep tracking. I don't think updates can fix its lacking sensors. It's a hardware issue, I believe.
I was wondering if it's getting better after the new major update but I already see some demands hihi.. I'm consider it again after Samsung claimed it will receive 4 year update support! but the battery and HR accuracy are holding me back
Can you compare which watch has most accurate ECG? How could Samsung have accurate ECG if these results look terrible
Please do scientific test on amazfit gtr 3 pro...
Mine galaxy watch 4 is showing heart rate of apple and also when I keep it in air above my hand.
It seems Samsung is doing what they always do...cram far too many features into a Device without making sure they actually work well...🤷♂️
What I would love to see is a side by side comparison between the Huawei Watch GT3 and the Garmin Venu 2 though...they are both supposed to be pretty accurate...
After trying to get the Galaxy Watch 4 HR to work for over a month, I can tell you the best thing to do is to return it or sell it and buy a Garmin watch if you care about it. The HR measurements are night and day, so much better, still to this day I've never had one drop out or hiccup, tracks every bike ride.
Please sujjest ''good health bands '' by your practical examination.
You should testing with a new strap instead the original one. I'm wondering why the watch has a good agreement and suddenly something wrong.
Bro does continuously heart rate measure good for ur human health bcz it always on green sensor light??
I'm a bit suspicious of this video. I've had the Galaxy 4 watch for a month and one thing that I've searched for continually and cannot find is any way to upload the data to to a phone.
I don't see any way that you could create these graphs since the best the phone will do do is tell you your heart beat at this moment or summarizer highs and lows for the day.. All of the other data is lost and from searching the Internet I have the impression that there is no way to upload is the way to upload more data for the kind of analysis that you are doing .
It also takes time to take your heart rate on the watch. You have to ask it to do it and then it takes a few seconds before the answer comes. So even if you kept recording the data it would not lead to very detailed graphs for the kind of workouts that you are showing.
I'm suspicious too because I think the results on my GW4 are not so terrible. Maybe it loses some peaks during weight lifting but not such think as he presents. And I don't think other smartwatches do it perfectly (like apple 7 or Huawei gt3 like he presents). For example if my actual heart rate is 150 BPM during one set of weight lifting the artery on the hand is in diastolic phase and the signal gets weak. The signal gets stronger when you stop the set and the blood flow increases. So practically no watch can track heart rate perfectly. Also there are so many factors that he doesn't take into account. For example if someone has cold hands, the signal gets also weak because of the reduced blood flow to the hands. And last but not least, the accuracy gets better as you wear the watch because it learns your patterns. It's not the same if I wear the watch for the first day and after one or two weeks.
Best reviewer for wearables!!! Keep up the good work!
I can't wait the heart rate review after update for GT3, and if is finally good maybe I will buy it. I can't wait the reviews for the others from my check list:
1.Huawei GT3 (I hope will be accurate like Apple watch and will add emoji support)
2.Amazfit GTR3/ GTR3 Pro (❌⛔)
3.Amazfit GTS3 (❌⛔)
4.Xiaomi Watch 2 (aka Xiaomi Watch Color 2 global edition, I can't wait the global announcement)
In regards to the old outside bike data with the missing HR values, the polar HR is also missing. Was that being recorded on a second device? Or did you remove it to illustrate where the watch had lost the HR data?
Hi! I remove both if the Galaxy has missing data. Just how I created my code at some point
Can you measure the Oura ring?
My Pro4 HR is accurate but it seems to take a long time for it to get the reading even when on always on mode. My old FitBit was way better for HR
Polar Vantage M2 sleep test? Pleeaaaseee
Thank you rob❤ Now am not going to buy any expensive android smart watch till they make HR accuracy good enough like apple watch.
i'm gonna keep my huawei watch fit
Make a fossil gen 6 review?
Great review, I've been really disappointment with galaxy watch 4 heart rate, (doesn't tell me resting heart rate) and it only tracks about 3 minutes of deep sleep every night
Same here with the deep sleep! Most nights there isn't any at all actually. If there is, it's less than 5 minutes. I was wondering if it was just me.
Oh I thought it was a right measure. Since I have this watch, I only have a few minutes of deep sleep, I went from a Honor watch to a GW4, and I was shocked by the deep sleep difference
I used the GW4, yesterday for the first time in a weight training session. I saw some reading that seemed pretty high, but, when I checked, manually, they were, pretty much, bang on.
Do you have a Polar H10?
@@MarcoPolo82 No, I have a chest strap and receiver but, after the pandemic, they both need batteries. I might get around to replacing them. So far, I am finding that the GW4 tends to get spikes that seem too high, I am thinking that when I do a strenuous exercise, like lifting, my heart rate goes up quickly, but the GW4 overreacts.
@@gwine9087 It happens the same to me. Heart rate goes higher during workouts, that it really is. Even after stopping workout, the heart rate stays or jumps to higher values. This is happening quite often, randomly, more when I choose the "other Workout". Difficult to track the bug and I don't have the option to report it to Samsung. The heart rate values were confirmed by me with another watches and even manually while resting!!
Ticwatch next please
You started to speed up your recordings or what?
perfect
Way more improvement needed Samsung
Is Huawei watch fit the most accurate heart rate measurement in its price category? Its only 79€ in here Finland.
Follow
Buy the polar h10, it costs 70-90.
And now it cost only 49€, I bought it.
After they see this video... Further new firmware will come! :D
Do Amazon Halo View when it comes out 👍✌️
Hey! I'd love to, but I do not think it is available in Europe
@@TheQuantifiedScientist Can I send you mine when I get it for the sake of seeing if it's worth keeping?
I'd be interested to see a sleep update for the watch4. The deep value metrics to me at least seem to have gotten. Considerably better to my Fitbit Alta hr that is on its' last legs.
Why Samsung messed up with this watch while apple found the right algorithm?
Make ticwatch
Thanks for the honest review .. Apple seems to be good winner here but apple dont want us to use it with android devices ..
I can't change to Apple eco system just for a watch .. sorry apple you win but lose !
Apple Watch still the king then.
No I’m not a Apple hater and I absolutely trust his results but those bands are horrible and strictly for fashion. The first thing other reviewers did was switch the bands.
Ticwatch gh
You just convinced me not to switch to the galaxy watch 4 😝
According to my observations Galaxy Watch 4 HR measurements are simply jokes
the heart rate of the galaxy watch 4 is very inaccurate (much higher than it should be) compared with the apple watch 7 which is accurate
Worse😰
Nowhere near the accuracy of Apple Watch. Poor implementation of software by Samsung. I would love to wear Samsung Galaxy Watch, if it did not have the inferior health metrics. SpO2, blood pressure, body composition still gimmick on Samsung.
Samsung is a joke . Still hoping for a decently precise Android watch as iphone is too expensive for the majority of the world population
4:19 Bruh!! you need to change your form. That's a poor bicep curl. You are using momentum to pull up the weights. Change your B-roll it's quite embarrasing.
Did you call your mom already?
Don't say that you do scientist measurements, it's not honest, you need to test with various context and several people, not only you. Btw there is a new update since the latest big one.
Thanks for the updated review. Much appreciated. Samsung needs to pull an Apple tactic: copy the technology, grab market share, and settle in court later. Honestly, for the size of Samsung and the resources they have there's no excuse for them not being neck and neck with Apple. Looks like they'll focus on emojis, new watch faces and other abysmal offerings such as blood oxygen and body fat readings. I can only imagine the conversations at Samsung: "We only have a +- error factor of 40bpm for heart tracking. That'll work".
It's because Samsung don't care. They're too big to care. They have plenty of fangirls and fanbois to carry them it seems, it's really odd, I see them defending massive faults. Samsung still charge a large price premium of course...
First
You guys, I guess, have heart problems, right? 🤣
The sensors of Gw4 is better than the previous series and that's enough for me. You don't just pay for the accuracy of this watch. You pay for the nice look,the stainless steel material,for the wear os 3,which is good enough and has a lot of potential to become even better AND some decent measurements(surely not perfect).Basically you have a smartphone on your hand.If you want perfect accuracy because you have a heart problem or you are a professional athlete,go get a Garmin watch. If you have an I phone go get Apple Watch. It's that simple.
Galaxy Watch 4 is garbage
This was another video sponsored by Apple. Total BS your findings.
It was also my thought. The watch's accuracy is not perfect but it's decent enough. No way what he presents.
Shut up, Samsung Fanboy. If he's is sponsored by Apple, he doesn't praised the Huawei Gt3 and GT Runner. I tested the Watch 4 with a Polar H10 and the Samsung showed discrepancies on the measurements. No way is what your thoughts.
