In this review we are going to systematically and scientifically test the ins and outs of the Galaxy Watch 6. The focus will be on the health and sports tracking capabilities of this new release from Samsung, based on more than two weeks of testing, which did result in a few surprises. We will test the heart rate tracking accuracy, sleep stage tracking performance, GPS tracking consistency and low oxygen saturation detection. As always, I do not want to waste your time, so there are timestamps in the description below, so you can easily navigate to those things that matter to you. Let’s get started.
Hello everyone! For those of you that are new to the channel, my name is Rob, and I am a postdoctoral scientist specializing in biological data analysis. This will be my first in-depth review of the Galaxy Watch 6, and compared to my initial review a few weeks ago, there were a few surprises now that I have about 4 times more data to work with. As always, I am not going to bother listing the detailed specs of this watch, since you can find those on Samsung's website. The most important things to know are: the screen is a bit bigger, the processor is a bit newer, it now uses Bluetooth 5.3 instead of Bluetooth 5.2 and the RAM has increased slightly, otherwise the Watch 6 is largely similar to the Watch 5. So instead of going through the specs, we are going to be purely focussing on independent testing of the performance of this watch, since Samsung did promise improved health tracking. As always, let’s start off by looking at the heart rate tracking performance of the Galaxy Watch 6 classic, which I tested during a total of 9 indoor cycling workouts, 18 outdoor cycling workouts and 8 weight lifting sessions.
Alright, but what's the final verdict? Well, it's not that different from my impression of the Galaxy Watch 6 classic I reviewed a week ago. In terms of health and sports monitoring, the Galaxy Watch 6 seems to be an average performer overall. It manages to track my heart rate well enough under easy conditions, but not when the circumstances become a bit tougher. The oxygen saturation measurements were pretty good actually, and with GPS tracking was good enough, as long as you don’t care about any of the details. On the other hand, the sleep stage monitoring wasn’t impressive, very often recording way too much awake time and limited deep sleep.

[@privxete4089]

1 thing i dont understand from Samsung, from why they set ''movements'' as awake moments, it says on their app/website, its really annoying, atleast i wanna see what is awake or movement...

[@GK-qc5ry]

Ticwatch Pro 5 please

[@ezasyakira7677]

Hi I'm ur new subscriber. Please make a test for Huawei Watch Fit SE.. Tq 😊

[@click381]

Watch at 100% change gives me 22 hours. Crap I only use watch as a phone and leave my S22 ultra home

[@Nitro2K11]

Many manufactures just list health tracking features but don't actually work properly. Your efforts are really important in helping those of us that really want and use accurate data to help us improve our health. Thanks for your efforts, it is much appreciated and very helpful for many of us to find the right device that really works as advertised.

[@humanchannel9421]

I'm pretty sure I could manually write a sleep tracking algorithm roughly as accurate as the Huawei just by making educated guesses based on your heart rate patterns correlated to your wrist movement. You need these companies to be accountable for them to produce accurate products. There's no real incentive to do so because most consumers aren't aware or don't care. The big contenders like Fitbit, Oura, Whoop, Apple etc. are obviously employing some kind of machine learning algorithm at the very least.

[@melihcigdm]

This is why i love YT i wanna buy something and keep looking for reviews then see random guy put a 40 min video about it. Thank you for interview dude keep up the good work 👍👍

[@TheQuantifiedScientist]

I appreciate that!

[@Tooooooony]

​@@TheQuantifiedScientist I'm confused by a difference between videos, the graph at 7:11 in this video "Heart Rate test: indoor cycling" shows the Galaxy5PRO at about 0.92 mark. I just came from watching the Galaxy5PRO review where around 7:19 (kzbin.info/www/bejne/amjGeZeDpJpnodU) the test is called "Heart Rate test Spinning" where it lands between 0.98 and 0.99. Isn't it the same test? why it got a lower value in this video? appreciate if you can clarify.

[@soomro81]

You know what, I bought a Huawei Watch GT Runner last year, and the Decision was totally based on your Analysis and Recommendation. I use it for HIIT and Outdoor Cycling and I am happy to see that I made a right decision and Its still going strong, so thank you!

[@seanlinehan1136]

One consideration for future tests if you ever want to expand: swimming. I mention bc i tested a watch 6 against my apple and garmins, and it was strangely the most accurate in a 25m pool BY FAR. I was pleasantly surprised knowing its limitations across the board

[@GadgetyMV]

Interesting! I have been using mine for swimming and it's nice just to be able to track laps, and to get a SWOLF readout. I imagined HR readout to be so so, based on the underwater movement.

[@smartbrreviews7290]

Me too

[@jeremylehner8652]

Thats the same with Me!!!! I love swimming swim laps all the time i tried the new FR165, FR255 then i was like nah im gling to exchange for a galaxy watch 6 and try it. All health metrics not great but the swimming data was perfect even identifying different strokes.

[@nuspeed19]

Love your work! Shame samsung don't seem to be improving much. No reason to upgrade from my 4.

[@ZMilosciDoGier]

Exactly 😢 and the battery 😬

[@TheQuantifiedScientist]

True! I guess no reason for FOMO here ;-)

[@krollpeter]

Or: The consumers seem not improving much! If people are happy with a beautiful OLED screen and some fancy graphics, whatever they mean, Samsung and others delivers.

[@GadgetyMV]

@nuspeed19 I agree no reason to get the Watch 6 when you already have a GW4. A question remains, if Samsung doesn't drastically improve their accuracy, will consumers choose a different platform when it's time to get their next smartwatch? Based on the evidence in Rob's testing here, I believe that what really matters to Samsung is to capture market share, aiming for the large majority of "middle of the road " users in terms of health, offering "good enough" and a few unique features, and other than that, milk the segment without any aim to be a leader in terms of accuracy. The aim may be profitable growth as Samsung's overall profitability has plummeted. There's probably a push not to invest, but rather on tweaking profit upwards. If they grow as planned, and are able to still turn a nice profit, they potentially read the market right. In addition there are other features that make a whole package, and it is this overall feature envelope that they're betting on matters to consumers. It's been said that Samsung switched to the Wear platform because they wanted to be able to offer Kakao Talk social platform in their home market. So the health part of the equation may matter less to consumers and these other features, as part of the total package combined create the growth.

[@FranciscoNogueira]

Love my GW 4 44mm. Just went to check my past cycling activities on samsung health. They seem pretty good in most cases with the exception of when I'm going really near 4+ floor buildings (which is somewhat to be expected, I guess). Again... I don't care so much for it's fitness accuracy as much as I do for everything else (notifications, weather, time, etc...). For under 200€ is everything I expected and some more.

[@Crazy1793]

This is why i wait for your analysis before i buy anything! Keep up the good work ❤

[@dominiksx]

I just found your channel and I love your scientific and dedicated approach to testing, you have my sub. Keep it up, your passion shines through 👌

[@J0pain]

Thank you for your wonderful work! Are you planning on doing a review on huawei watch 4 and ticwatch 5 ?

[@chiquitabananana9641]

Rob, I ❤your reviews! So glad to hear you call out sleep apnea! Do any fitness trackers have similar continuous SpO2 tracking to that ring you wore?

[@n0n1m03]

@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!

[@shaf3006]

as a first responder your reports give me some relief, once we respond to an emergency call and we were out of the standard equipment, I put my GW6 on one of the patient , seems not a serious case and I never see him again

[@carrickdubya4765]

did the patient disappear with your watch ?

[@jordanwright5231]

Dude, you are saving my life right now. As a fellow fan of data, having access to coefficients of correlation for these watches is huge to me. I'm curious about your sample size in case things like manufacturing lot, wrist fit, etc also affect the performance of these while acknowledging that I personally wouldn't spend $1000+ to buy 3 of the same watch to test these things (nor would n=3 give much statistical power against the factors I mentioned). TLDR: You are who I want to be when I grow up.

[@actorjay]

Always enjoy your reviews. Thanks!

[@tamaspeczoli2503]

Hi Rob, your test is very good and useful and I would like to ask you mention for these watches ' battery usage time as well!!! Thanks

[@jeetdeshmukh]

Good to see you doing more and more smart watches and bands

[@TheQuantifiedScientist]

Thanks! Happy to see you like it !😊

[@marcusmarcula]

Thanks for the update as I was curious about the size of your sample from the last video you posted and from what I had observed it seemed that the watch was not functioning correctly and a bit laggy.

[@mboiko]

Here are the main differences between Bluetooth 5.3 vs 5.2: - Bluetooth 5.3 will offer faster switching between low-duty and high-duty cycles and is therefore more energy efficient than 5.2 - Removing redundant data will also reduce energy consumption. - Bluetooth 5.3 should also reduce interference, and boost signal quality.

[@McLovin16x29]

Danke rob für den ausführlichen video, wäre aber interessant wenn du den EKG und Bludruck bewertet hast :)

[@peterjapan1825]

Bloodpressure measurement seems to be accurate (within the boundaries of the method) on my gw6 classic. I compared it a few times to a certified instrument. HR measuring also seems to be fine - at least when you dont do sports. Overall im very happy with this watch. Had the gw4 classic and sold it because of the battery-life.

[@OutlawCaliber13]

I manually took my own blood pressure(difficult lol), and it seemed to be within range of accuracy.

[@lucsfreitas]

You mentioned that you swapped the GW4 for the GW6 because of the battery. Did you feel much improvement at this point?

[@peterjapan1825]

@@lucsfreitas Absolutely. But I also changed my routine. I always lay it on the charger while I'm showering. So I don't even think about the battery.

[@ismaelrivera1999]

I think that the inaccuracy of the heart sensor could be related with band size reduction. I have a Galaxy Watch 3 -45 mm with a sport band 22 mm and when I compare it with my Iwatch 7 it’s stays close to it. A 20 mm band on a 47 mm watch could move a lot depending on the sport activity.

[@great.rajeev]

Yup there can be some inaccuracy due to watch band i.e. the sensor close to the hand for better readings.

[@steadycompsltd.]

Thanks, these really are super useful. Subbed.

[@giridhranpalani3139]

Was hoping for the watch 6 to be a step up in terms of software at least for enhanced tracking. Sad to see that it can't keep up with older gen smartwatches like the Apple and Huawei watches. Thanks for the review Rob! Awesome as always ❤

[@AntonelloTauro]

Congratulations for the thorough review! I'm considering purchasing a smart/sports watch, and I'm very undecided between the Huawei GT3 (not Pro) and the Garmin Venu 2 Plus. I only do exercises in the gym in the evening... which one do you recommend? precision on training and characteristics? thanks!

[@zofg13]

Hi, great video, any chance you can introduce tests for ecg, would be great to see how they perform on apple/samsung watches.

[@bhujelkedar]

Hi Rob, I ve been via some of your reviews Amazfit GTS 4, GTR4, Huawei too, i saw 3rd measurement of heartbeat for all were decreased while Polar chest strap was showing them increased, whats the reason for that? 1st good, 2nd ok and 3rd worst!!😁

[@hugoooobr]

Hey it's been a while, and software updates have been made right? What if you re-test this watch? Since it's the main watch from the main Android brand

[@amirhussein834]

Hey i want to leave a vidro sugestion. Could you compare the diference in measures between using the watch pretty tight vs using it more loose or on top of the small bone at the end of the arm?

[@krollpeter]

Thank you, Rob, for your work 18:28 A device that gives automated health advice should be required to possess a certain level of relevance, or as you said it, accuracy when giving sleep advice for example. If the vendor does not stand to its product and there is no guaranteed accuracy, then those devices should be clearly marked "For Entertainment Only!"

[@humanchannel9421]

I'm not really convinced that 70-80% accuracy would be enough to provide medical advice. Imagine being prescribed statins to lower your cholesterol because the doctor administered a 70-80% accurate test and you were a bit on the high end.

[@FacundoMontoya]

@@humanchannel9421 Statins are not a very smart example. It's best to stay away from them. Few advantages and many disadvantages.

[@quackman]

@@humanchannel9421 The app goes out of its way to tell you it's not accurate enough to be medical advice.

[@limta74]

Any way to test to speed pace accuracy on each SmartWatch? for Hearth rate you using Polar chest strap to compare the accuracy, What we can use to compare the GPS accuracy?

[@soulragepage]

Hey Rob, thank you for your wonderful videos they help me decide which watch to buy. All that aside though I came across an interesting situation. I have a polar h10 chest strap heart rate monitor. Per your recommendation and I love it. It works great. I was using it at the gym the other day, and I noticed that it seemed to be connecting to my new Galaxy 6 watch. There's only two ways that this would be possible, and I'd like to try to figure out how this is happening. Unfortunately calling tech support for Samsung products is like pulling teeth. Not good! So I was hoping maybe that you could help me understand what's going on here. It seems like my heart rate monitor is connecting to my watch even though I haven't paired it with Bluetooth. The only way I can figure this is happening is either the Bluetooth settings stored in my phone have been downloaded to my watch and the watch is using that to connect to my heart rate monitor automatically, or and I think more likely the watch is connecting through ANT+. The only problem with the second theory is that I can't find a single spec sheet that mentions ANT+ for the Samsung Galaxy 6 watch. And I tried calling tech support and they had no idea what I was talking about. I had to explain what a heart rate monitor was! Lol. All that to say, what's your theory on this particular situation?

[@Raghavacharisampath]

Hello: That sounds interesting. To confirm it is indeed reading from H10, unbuckle the watch and set aside and see if it is still reading from H10. If it is, there could be 2 reasons. The Samsung health app on the phone can pair to H10 and if you open the watch app it should show the reading from the phone live. The 2nd option is Samsung Health has gone thru a major upgrade just in the last couple of days. Check latest sakitech video on this.

[@yildiraykomurcu]

Thanks Rob, I would expect the blood pressure test in the full scientific review as well. This is an important health metric as many people around the world suffer from high blood pressure. It is easy to test it on Samsung Galaxy Watch 6 against a reference device, like a traditional upper arm blood pressure monitor or like Aktiia band, a certified blood pressure band. You seem to have dropped step counting, you can just as well drop GPS accuracy test since you are not giving a quantified score which shows how well the GPS performs. PS : I also test my blood oxygen level with O2 Ring from Wellue in flights and never had results such as 68%. Thumb is recommended for that device. PS 2 : Samsung Watch 6 review 3 in a row was a bit boring. What do you plan to review next ?

[@magicalkorok]

No blood pressure monitor in America.

@@plasmasupremacy9321 Due to regional government approvals which in the US the ECG got approved. And you can use it now just not a launch so I hope the Blood pressure gets approved as well soon.

[@gerudoqueenriju]

I have the watch and can tell you that blood pressure measuring works really good. The difference between a professional arm measurement is very small, like 131/84 on the professional device and 128/83 on the Samsung device.

[@Feltified]

Would you consider reviewing the new Garmin Venu 3 (or 3s)? It is one of the lead competitors for the Galaxy Watch 6 and would be really interesting to compare.

Thank you for your hard work! I was really looking forward to change my watch 4 however with your review I do not consider it to be worth it. The strange thing is that apple watch is almost perfect in tracking and samsung had lots of time to figure this out but they somehow haven't. I will be waiting for watch 7 and hope this would change.

8:50 It could be the newer watches are lighter so they bounce more as if you use a figure HR/O2 scanner they are with in 5 points of each other.

[@zemiguel2550]

nooo Rob! I think you had a great opportunity to retest the GW5 and discover if the sensor on the new GW6 is faulty or the software updates messed up the accuracy. I'm looking to buy the GW5 but if the software updates messed up the accuracy, and it's now dropped to be on par with the GW6, I'll pass

[@TheQuantifiedScientist]

Hi! I am retesting the updated GW5 now, so stay tuned!

​@@TheQuantifiedScientist this is the reason why you're my favourite smartwatch reviewer!!

Or even the opposite, there are new improvements

It better to see the actual situation. We can get better reference points. 1 measuring is not a measuring - I learnt this fact. Do not compare the newest model's test to a 1-2 year(s) old results. When we compare to the whole group OK, but not quite good when we check the brand opportunities. Many softwares have been changed until this period. That's my recommendation.

Thanks so much! I am actually retesting the GW5 as we speak, at the same time as testing the GW6!

[@ocelkavole]

Will there be a new review? GW5PRO@@TheQuantifiedScientist

[@CoachApuma]

Amazing to hear! I'm considering buying a cheaper GW5, and your Sleep Tracking EEG comparisons are the most useful information regarding their performance on the whole internet@@TheQuantifiedScientist Would so cool if GW5 could compete with at least the lower performing Apple watches. From what I've heard there was a slight downgrade in sensors between the GW5, and GW6, because Samsung was concerned about their sensor light disrupting sleep or something? So it's possible that with the latest updates GW5 is the better performer in this test

[@bvatruck]

Excellent 👌. You will test Huawei 4 pro?😊

[@akkypatil05]

Nice comparison ❤

[@specialagentzeus]

Was each test done once or a number of times?

[@DavidEVartanian]

Hi Rob, I'd love to hear about Huawei Watch 4 Pro and GT 3 Pro. Last review was a year ago and after many updates I expect the performance to be different. Thanks a lot for your amazing work!

[@abdalrahmanarrob6802]

Yess I would really love to see a test for the Huawei watch 4

[@abdalrahmanarrob6802]

Their new models are not cheap, I wonder how much better they got

[@alexkramer7351]

Zou u ook een test kunnen doen van de garmin Desent MK3I

[@apurvjaiswal8670]

Could you also do a review for ultrahuman ring air if possible???

[@mrnicbst]

I did a couple of runs with the watch 6 44mm and my Fenix 7. The HR for both was very similar, showing the same value or very close. The Gw6's pace is a complete crapshoot though, so not useful for running. I returned it.

[@CeDubble]

What if the difference during the outdoor bike is coming from the sensor position difference from the wrist as opposed to being closer to the heart. Add into that the muscles in both different areas having an effect on the sensor.

[@igormalusevic]

on 26:55 you have on higher position Galaxy watch 5 pro (highlighted in blue) and also same watch below samsung galaxy 4 so is this in blue galaxy watch 5 pro and those below galaxy wach 4 is galaxy watch 6 pro?? Confusing.

[@HenPapirman]

Great as always. Questions: - What model is your Oximeter? (Not the ring). - What do you do with all of these watches after testing them?

[@TheQuantifiedScientist]

Thanks Hen! I'd actually have to look up the brand, and I am not at home, so I cannot check now. And, I just have a big bucket for all the watches, so I can retest them once a new version comes out 😅

[@HenPapirman]

@@TheQuantifiedScientist Cheers for the reply. I've been looking for an Oximeter recently and suddenly I saw yours, so, if you don't forget, once you come back home, I'd appreciate if you took the time to check it and let me know. Have a good one.

[@aleck156]

As I''m looking for 42mm in diameter smartwatch, I've narrowed down my search to - Huawei Watch GT 3 42mm - Garmin Venu 2 Out of these two, which one would you recommend for fitness tracking first and smartwatch functions second?

[@Laughing_Individual]

Garmin no centest

[@garywucherpfennig242]

Could you do a review on the Sleepme sleep tracker

[@iros7706]

I am seeing these comments and i wonder ,did we watch the same video? What I am getting from this is that a watch which costs 300$ is not the best one compared to more expensive watches like apple watch which are a couple hundred bucks more. It does a decent job at everything and although it is not the best out there i dont think that if you want accuracy in sports you would go for that watch. I think its a very good "lifetyle" wearable which can help you track some things that might be irregular and makes you go see a doctor or something. For me for android its one of the best choices for regular users.

[@MarcoPolo82]

You're right. Who's bought a Samsung or Wear OS is more interested in watchface s, download apps, reply notifications, etc. The health accuracy during exercices is the last thing to think about it. Who's take sports seriously, bought a chest strap, a fitness watch like Garmin.

[@SQUID0NKEY]

Absolutely. Compared to other watches, this watch is still good. If you really want to have accurate measurements, you won't get them with a watch, a watch is not a medical device. I really like my Samsung Galaxy Watch 4 because I have hypochondria and am really worried about my health basically all the time. This watch helps me to feel safe with my health because I don't need to worry about me having issues with heart rate or blood pressure. And if something would seem of, I can just check on my watch. And if my data is somewhat weird for a week or longer I can visit my doctor and can even show data, with which my doctor then can test the right things to determine what exactly and how bad the health issue is. It's a bit strange that people expect a tiny watch on your wrist to be able to do the same, as a whole cabort filled with medical devices in a doctors office...

[@DRT813]

​@@MarcoPolo82I'm actually mostly interested in a smart watch for the health and activity/fitness data. I couldn't care less about notifications, they are already annoying on my phone, I'd probably deactivate them on a watch. The problem with a Garmin is that a) according to his videos they aren't great at tracking either and b) you don't wear a chest strap 24/7, so if you have heart palpitations like me, you want a more continuous tracking. Regarding the price it's interesting that some cheaper watches (Huawai for example) are much better with tracking than the Samsung watch and Apple is miles better, while costing "only" about 100 Euro more. That's not nothing, but considering that one delivers pretty accurate data and the other does not... would buy an Apple watch in a heartbeat if I wouldn't be stuck in the Samsung/Android ecosystem with my phone and tablet.

[@DRT813]

Apple Watch is $400 rn, so that's just 100 bucks more. That's expensive, but compared to spending $300 for inaccurate health data... The bigger problem is the cost of an iPhone compared to a Samsung phone, which sadly I can't afford, so I'm stuck with watches that give me data that might be right or might be wrong (but why would I need it in the first place then?).

[@SQUID0NKEY]

@DRT813 Well, the galaxy watch 4 only costs about 100 bucks rightnow, according to this guy, it's the best one of the galaxy watches that is almost as good as the apple watches. That's 300 bucks less than the cheapest Apple watch. If you ask me, Apple is still way too expensive in general...

[@blackness010]

if its connected to the phone is the gps tracking better?

[@spangl36]

Thank you so much for this review. I am a gtr3pro amazfit owner but I am not pleased with it... I was thinking to buy gw6 44mm but now after I saw review I am thinking to buy gw5 pro. The only think I need to know is that if the galaxy watches measure steps even if your hands are occupied. Thank you in advance 😊

[@Altafkhan143]

Hi, can you also please test Ultrahuman Air Ring and it’s accuracy…which can be close competition to Oura Ring
