It would be nice if you could redo the analysis after a few months of release and with new possible software updates that may improve the results of the device
Agree, it's a lost war; the decent option would be fitbits but paying a monthly fee for premium content after investing 250$ in the damn watch is grotesque.

Thank you so much for the very thorough test results! I ordered a Watch 6 Classic, mainly to control apps, but also for heart and sleep monitoring. I hope they can improve with updates...but if not it is probably still okay for me. They really need to step it up, though...
I just ordered mine.I hope they can fix it and make it more accurate 😅 How have you found the tracking to be so far? (Seeing that you made this comment a month ago👀)
@@RicstasTech I think it does an okay job for comparing one night to the next, generally. I have honestly stopped wearing the watch to bed. I slept fine with it, using the Samsung fabric band, but it just wasn't ideal. Ultimately, I don't think sleep tracking, even if accurate, really does much for me. I know when I SHOULD go to sleep and I know that magnesium supplement personally helps me sleep better. What more do I need to know? I'm more interested in BP monitoring...which isn't allowed unless you do something with the software. Supposedly it's real easy to do, but I haven't done it yet.
@justinkase1360 thank you so much! I am stoked to get mine, I got the sports band and the fabric band as well, looking to see what us more comfortable when sleeping, or if it will be chilling on my bedside table charging. Appreciate your response 💪😁
@@RicstasTech I also received those two bands. Fabric is more comfortable and actually looks good, IMHO. I had the Watch 5 and never wore it, but I'm really liking this Watch 6. I use it A LOT for Spotify. The volume control using the bezel is awesome and I can favorite songs right there on the watch, even change from DJ to various playlists. Anyway, enjoy!
Great analysis. Thank you! As many others here, I am also curious about Huawei Watch 4 PRO performance, since it has sensors from Watch GT 3 PRO which tops your HR accuracy chart along with Apple Watch. Huawei also claimed they improved sleep detection, which was not that good. Another "true smartwatch" alternative to Samsung Watch 5 PRO what would be great to see is Ticwatch PRO 5. It is missing eSIM version right now, but that may not be deal breaker for many.
Same, Lukas. Look forward to the review of HW 4, but I have already purchased it though and love it. Especially the price, since initially I was thinking of Garmin, and it's not the case anymore.
I have been in touch with Samsung and have had my watch since the 6th so 5 days before release. All of the inaccuracies seen in this video I have also noticed. However I believe the physical hardware is probably not the issue. I was assured by multiple support associates that the watch was designed with the new updates in mind that are coming to android. I would hope that after an update or two these issues will be fixed. Please repost comparisons afterwards to see if there is actual improvement.
@fahadbinfarid5927 it's inconsistencies held up even after a couple updates. Not super impressed for the price. Hoping future iterations can be better.
Loved the review as usual Rob! Thanks for your input and I really hope @Samsung takes more reviews like this into consideration before releasing their next smartwatch!
Thank you for another excellent review and hard work Rob. I already cancelled my watch 6 classic pre-order based on your initial findings and it's bittersweet to know my decision was the right one. I cannot support Samsung in their watch devices until they improve the accuracy of their health and fitness measurements to be competitive.
I wouldnt take this video as guide. The sampling on the HR polar 10 is extremely low on the Apple watches compared to the Samsung watches in the spinng, biking, weight lifting. The sampling of the HR polar 10 should be constant in every review, but i see that it is lower on the graphs of the apple devices vs the samsung ones.

@@thechuches3879That is a valid observation that I hope Rob can answer. My decision was largely based off of his detailed analysis, Samsung's history in this space and unfortunately many other reviews like DC Rainmaker's which confirm such inaccuracies relative to competitors. DC Rainmaker's Review: th-cam.com/video/HuyOE2NA7rA/w-d-xo.html
As always, great video. Appreciate the time and effort you put into these. Another disappointing showing from Samsung. I wish Samsung would hire you to lead their analytics team to help them make a better fitness device!
The time has come for me to replace the phone and this time I gave up the Samsung I had been buying for many years in favor of the iPhone 14 PRO with Apple Watch ultra. For now, I'm getting used to the new system, but at first glance, my old Galaxy Watch 5 doesn't even stand up to the competition! I feel like I finally have the right equipment, thank you Rob! 👍
I don't want to be samsung biased but I have the watch as well as the huawei one and both the heart rate and the sleep tracking appear to be almost exactly the same when I tested the two during a workout sessions and in the morning for sleep. Maybe it depends on the person but for me I get very very similar results. For example the heart rate on the samsung now(when writing this comment) is 76, while the huawei is 77, the lowest and highest heartrates of the day are 44:140 and 44:139 and the sleep is 8h11m to 8h01. The max difference between steps at the end of the day is 200-250 with over 15,000 total steps. In conclusion during my testings the results are both mainly the same.
Thanks a lot for all your work. After watching about 15 videos and telling all my sport friends about your channel, which I had found on Reddit, I finally bought a watch for myself. No, it's not Galaxy. I decided to go for Huawei. I hope the 4-version will be as good as the previous one. I'm sure in a month or two there will be a review here, which we all look forward to! You are a hell of a man. I can't believe you are just the only one on the whole Planet who did something that everyone needs and nobody thought of.
Thanks for the detailed testing of Galaxy Watch. Disappointing that Samsung still haven't figured out to get as accurate in readings as possible. This really stops me from buying Samsung phones as there's no point in paying same as Apple watch but getting a mediocre product. As always thanks for taking the time to test these watches and giving us the correct opinion before putting our money into them.
Thanks for the in-depth analysis. 👍I've used the Smartwatch 6 to track overall sleep time, the last couple of nights and to me it seems pretty accurate. I also fell asleep during the day yesterday, and it picked that up. I'm not so concerned about REM or light sleep, at the moment. Glad to see HR at rest, is overall accurate enough and blood-oxygen as well. When I exercise, I cycle outdoors and will not be wearing my watch for that. Don't want a tan line 😃, and don't need it. For GPS I have a Garmin and the app on my phone. Again, thanks. Look forward to any other updates.
Thank you very much for your existence!!! As a man, who very deeply tries to find a right buy for myself, I spend a looot of time for searching and comparing things, to make a good/perfect decision. Your channel and work with independent review is a honey for me. Very structural, great graphics, great comparisons. Because it's too hard to find a right gadget in this mess of them. Thank you one more time!
I would like to see a number for the percentage of overall sleep stage agreement, not just a graph of the single (worst) and aveage percentage. Perhaps this could be added as a column in the agreement chart. Maybe, also, if your going to plot the worst, plot the best... Also, mixing measurements from different references on the same chart would me much more useful if that chart included measurements from (at least) 1 reference device for every watch. Yes, this would mean multiple measurements (for a single watch) on the graph, but at least the data would have more relevance. For me, the issue of accuracy isn't just relevant to the best available measurements but also relevant to other devices. When the graph plots points from different reference measuring devices, the relevance of the plot points can be lost (between some devices). That said, I really appreciate your approach and testing. I find it extremely valuable even as is.
Was about to buy the Galaxy Watch 6 Classic. So glad I watched this before pulling the trigger. Going to wait for the Pixel Watch 2 as the Pixel Watch 1 appears to do much better than Samsung's efforts
@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!
I dont know if I missed it, but how many nights of sleep tracking were tested? I've heard many say, that continuous use of the watch could improve the accuracy of that.
Hi scientist! it would be really interesting to test these popular watches again after some time to see how software has improved/made them worse or model mumbers
was waiting for this and finally got my watch 6 classic as well. The results from previous review are still holding, including the R with POLAR, the inertia in catching up to changes. Idk if the performance merits the price tag, and Samsung probably knows it too, that's why all the deep discounts (got 30%+ discount myself). Just holding it for the sake of the "ecosystem", and it looks alright.
Nice vid as always. I got the Classic 4 for may mom 2m ago (needed some medical monitoring), I compared it to my Apple and I found it actually useless. When I saw the 6 and the "sponsored" propaganda, I thought it was going to be better.... Wish I had waited for your review before wasting more money in this brand. It's better than the E610 I got recently (for a fraction), that one I knew was going to be a wa$te, and this one is a bigger waste. Instead of these 2 I could have probably just waited one month and bought the next Apple Watch. Cheers and keep the good work- Vielen Dank.
In every video I watched regarding this watch, I mentioned your channel saying how you test and compare these watches. I was counting on getting this watch, but after seeing your reviews, I shall wait yet another year. The most important features I look at are hr (daily use - not sports) general health tracking and sleep tracking. I've read a few stories about the Apple watch saving lives, not so sure this watch will provide the same service. Can you not contact Samsung and show them your results? For me, personally I was so disappointed.
I was hoping you could do a review on the regular version the Galaxy watch 6 and see where that falls in line compared to the rest. I purchased both models pre-order and ended up keeping the regular and sending back the classic. This decision was partially made from watching your videos get the first reviewer who actually does real-world testing alongside a medical device can you please do a test with the regular Galaxy watch 6
To me, it looks as if the sensors have not been upgraded - at all. Personally I am disappointed by Samsung, I would have expected better. Nice smartwatch, mediocre health tracker: that's what I am taking from this. Should I want to replace my Galaxy Watch 4 Classic I'll check out Garmin and Polar. no kudos to Samsung this time.
The ECG works and is FDA certified. I've actually had really valuable use of it, so... it's a mixed bag and not a blanket statement. I'm living proof of it! HRM isn't that bad either for regular stuff, like walking and steady state use. Bioimpedance is OK and they are alone in the Android market for this afaik. The disappointment to me is that their sleep algorithms don't seem to be improving, and they must have a huge database of users, and that Apple has shown what is possible in terms of accuracy...
@@GadgetyMV Good. I've decided to skip the Galaxy Watch 6 Classic ... I do want to see improvements on the health tracking front. Improving sensors is not easy, and there are tons of patents around it and also around the algorithms that make sense of the signals those components deliver. It is really costly, takes a lot of investments and payment of fees and royalties to third parties. Samsung - from my perspective - stuck with what they already have and refrained from any investments re the health tracker functions. They just added some cosmetic bells & whistles around the Smart Watch functionalities but left the core health tracking functions untouched. That way Samsung ticked off some good old marketing check boxes at zero cost. If Samsung continues this path (for cost reasons) it will continue to deliver a nice Smart Watch combined with stale health functions. I am a Samsung fan but here I will part ways. .
Samsung Galaxy Watch has some additional features that the competitors lack, for example, blood pressure and body composition measurements. You could test and include these metrics as well in the full review Rob. Anyway, it is a good review and we don't see much of an improvement on Samsung side with respect to previous generations. PS : Rob, you always say the heart rate measurements when biking outdoor are difficult due to the bumps in the roads. While it is true, do you ensure a firm contact of the watch with the skin during the entire trip ? I do it by tightening the watch strap and whenever it gets loose, I stop and readjust it.
Others have tested the bioimpedance and compared it to DEXA. It was off about 20%, and varied between users. The variation within a user didn't seem that big. On me the variation isn't big, so it seems to track me well enough. What I do is take at least 5 measurements, remove the top and bottom one, and average the rest. That said, I'm very lean and I can track visually as well, and it seems to correspond well.
@@tthyssen Sensor galore. Samsung knows features sell. The average user might not know how accurate or inaccurate sensors are, and other aspects also influence the buying decision. Samsung is targeting the mass market. I believe the market also comprises those that buy data from Samsung, and it would be interesting to understand how the accuracy influences their decisions.
Just got my Watch 6 Classic, swapped my Watch 4 which was quite reliable, love the Classic watch 6 appearance. I've done a few exercises wearing both the 6 & 4, they give very similar readings. The watch 6 is good only because it's a newer device that's all, nothing else beyond that. In terms of accuracy, I've come to accept that for watches acceptable accuracy is all that's needed, the GW is acceptable.
I think that your tests are missing one very key test and that is a calorie count test. One that counts your whole day and one that counts only your workout. This is very important for me and for many people that workout and count calories. In my testing done loong ago, Gear S3 from samsung failed horribly. They were basically making those numbers up and did not use the heart rate data to compute the calorie count, even during workouts. However, second gen of apple watch were already amazing at this, calculating quite accurately the amount of calories burned. Please consider this as a new addition to your metrics. Thanks.
Hey Rob, just wondering if you wear watches for a couple of weeks prior to doing the tests to allow it to "get to know" your body? I have read a lot of smart watches require this learning period before they start giving accurate data. Thank you so much for your videos, you are providing a public service!!
I really appreciate your incredibly rigorous testing. Just got this watch, and as disappointing as it is to find out that its data collection is rather mediocre, at least I know not to put too much stock in it now.
I have a Galaxy 5 Pro, I am 56, a bit overweight, and have sleep apnea. I have worn this watch during three separate sleep studies, and for me it is far more accurate than what your test shows. My doctor was amazed how close it was around 85-90 percent for O2 and around 80% for sleep stages. That is the problem with this review, you really only have one data point. It is possible that companies like Apple calibrate their watch for younger fit individuals whereas companies like Samsung calibrate their devices for folks like me, I.E. the people that really need this type of data. It would be far more valuable (and conclusive) if these devices could be tested on a wider range of individuals. How difficult would it be to partner up with a sleep study center and get people wear these watches at the same time? This good information, but it would be far more interesting than just testing on yourself.
I'm so gutted by these results! As a Samsung phone user, I so desperately want this watch for the eco system, all the apps and cool features...But what's the point if all the health and fitness tracking is so abysmally inaccurate?! (Which is the primary purpose of a watch for me). Bitter disappointment! Epic fail Samsung!
Hi Rob, nice review as always! I have a question. It seems to me that the video shows the performance of the Galaxy Watch 6 Classic 43mm. Wouldn't the Galaxy Watch 6 Classic 47mm be worth trying too? Having a larger battery perhaps the algorithms could be slightly different. This would also explain the better performance of the Galaxy Watch 5 Pro. Thank you
Heavier watches seem to have worse HR measurement, and I wonder if the regular GW6 would measure HR more reliably than the GW6 Classic. However, spotty HR measurement is easily remedied by the ability to connect with a separate HR monitor, like the chest strap. I wish the GW's could do that natively. The ability to access other monitoring devices is a huge benefit of Garmins, for example.
Excellent video! Very valuable measurements and overview of results. Thanks for explaining so clearly. Would watch size be a significant variable to analyze? Not sure if the size would impact the contact of the sensor with the skin? Also, the band type/material may also impact the way the watch "slides" on the wrist.
Hello Rob, Thank you very much for your excellent videos. I would like you to test the huawei watch 4. I remember your test on the GT3 pro with good results except for sleep. I would like to buy a GT3 pro but maybe the huawei 4 is really better ? I need your tips. Thank you very mutch !
That's why I have often had a Garmin on one arm and a Galaxy Watch on the other when doing more serious fitness activities...they are okay for very casual use but are a far cry from professional grade. I still bought a Watch 6 though...but it was 50% off with my Z Fold 5!
It's interesting there are big differences in measures between Galaxy 4, 5 and 6 on the other side. Great videos as always!!! Also, you are intelligent to point about personal differences at the end of your videos and that points me to a personal question I hope you can answer, what is your height and weight? Best regards.
Great video, thanks! Maybe it would be helpful to compare chest straps at some point. I have a PowrLabs that seems pretty accurate compared to my pulse oximeter. I decided to get a Garmin HRM Pro Plus to go with my Garmin watch and get extra walking /running info but had a lot of trouble with HR accuracy compared to the pulse oximeter. The conductive electrodes on the Garmin didn't seem to get a reliable signal from my skin and would put out readings that were off. I finally returned it. Maybe I'll try the Polar strap next.
Excellent video Rob. Does anyone know if software updates have fixed the issues? I have Watch 4 now and was looking a upgrading but after watching a few videos on the different brands, looks like Apple is best in class.
That's a great video. There's one thing though, that makes me wonder. Watch 4/5/6 normal/pro/classic all have the same(!) main sensors. So why do they differ so much. In at least one graph same goes to Apple Watch Ultra compared to other sensorwise similar Apple watches. I guess it's either statistics, differenzt wear positions at wrist or newer software. Would be interesting to verify that by choosing an older watch again if it reacts differently now I.e. similar to the latest model.
I have been sleeping for some nights with both the 5PRO and the 6 Class, swapping from left to right in between the nights. The sleep tracking results differ majorly between the two. The only thing they agree about is the end time of the sleep. There IS a difference between the software of the two; I have pursosly not updated the PRO 5 to the latest version (which would bring it to the same version as the 6 class.
Hello, thankyou for checking this smartwatch into depth. I got an question, would the update of week 35 so last week of august, improve it? They said its stable, and not in beta anymore for Galaxy watch 4-5. Only America-Korea has the beta still.
Your reviews are awesome! I really like the data based comparisons although this doesn't make my search for a good watch easier. Nothing to with your amazing videos but there seem to be a big difference between apple products and 'the rest'. Or did i miss on? Is there an android watch with: hr sb/ob/wl aver. r: 0,9+ sleep match aver. 80%+ with rem 60%+
Thanks for the rigor you put into these reviews, could I request a device to be reviewed? The Redmi Watch 3 Active looks like a very interesting little device
I'm not surprised that there are some discrepancies in sleep stage tracking. I wonder if these smart watches are using PAT to produce an estimate. The doctor, who provided the research for home sleep tests for OSA was the former CEO of the company that pioneered the devices. He then sold his company to ResMed, who happens to be a diamond donor to the organization who published the scholarly journal. Home PAT tests were classified as "Technically acceptable." While they achieved diagnostic congruence with a PSG for severe OSA about 67% of the time, mild or moderate congruence was significantly less. Bottom line, if even a medical device misses almost a third of the time, consumer devices are at best giving you a ball park estimate and is best used to measure trend data over time instead of trying to use it as a medical device.
Wow this video is so detailed. Thanks so much. I currently use a samsung phone and want to upgrade my fitbit versa to a Samsung watch.. but now I'm not so sure and may actually be a downgrade. I hope samsung sorts this out
Damn you quantified scientist ... My samsung ecosystem was about to be completed with this watch ...already has ear bud pro2 ,S23 samsung, charger and powerbank ...but i know need to carry on with my old venu sq 2
Hi Rob! Due to the bad results of the SW6 is it a sensor problem or software and algorithms? If software issue, can it be solved in the future? Thanks for the great review 🙌
This a question that is asked every time that new Samsung watch is released and there is always someone in the comments saying that accuracy will improve in the next few software updates... but it never did for any previous Galaxy watches afaik. So, you can risk it and hope that it happens this time, but probably it will not.
@Genial1990 Thank you for the satisfying answer 😁 I bought the classic version 47, I've been using it for about 10 days now but I will send it back today, and I will buy iphone 15 with apple watch. I will try it with apple this time, hope I won't regret it.

There IS a difference between the software of the two; I have pursosly not updated the PRO 5 to the latest version (which would bring it to the same version as the 6 class.
Hey, Rob! It would be really interesting if you compared the sleep tracking of garmin watches to the firstbeat bodyguard 2 or 3. Garmins algorithm is actually made for firstbeats bodyguard, so if you compare them you can see if it's the algorithm itself that is bad, or if it's Garmins watches that just don't work well with it.
I can't wait until the arrival of my Watch 6 Classic to maximize my Samsung ecosystem to guage my exercise performance output and easily make adjustments along my way w/ my Z Fold 5.

Hello! Are you planning to make a review of Huawei Watch 4 Active? :) Greetings from Poland! :)
It's so depressing being an Android user when in the market for an accurate watch.
Agree, it's a lost war; the decent option would be fitbits but paying a monthly fee for premium content after investing 250$ in the damn watch is grotesque.
Huawei Watches are so accurate.
The only brand compared to Apple watches
You guys never heard of Huawei watches ? Watch 4 pro or gr 3 pro
Huawei GT3 Pro (46mm) is the best android watch ;)
Don't know about the GT4 (Pro) though.
Huawei watches and bands are way more accurate and also affordables. If you're only looking for accuracy they're more than great
Nice video. Disappointing to see that in 2023 Samsung, as the premier Android maker, is still lagging behind Apple and by such a large margin.

@@thechuches3879That is a valid observation that I hope Rob can answer. My decision was largely based off of his detailed analysis, Samsung's history in this space and unfortunately many other reviews like DC Rainmaker's which confirm such inaccuracies relative to competitors.

Great review as always. I have a question, any schedule to review Huawei Watch 4 and 4pro ? thanks
Come on Samsung get your stuff together.
Perfect video! Thank you!
I pre-ordered Galaxy Watch 6 classic, and already regretting it...
As always, great video. Appreciate the time and effort you put into these. Another disappointing showing from Samsung. I wish Samsung would hire you to lead their analytics team to help them make a better fitness device!
The time has come for me to replace the phone and this time I gave up the Samsung I had been buying for many years in favor of the iPhone 14 PRO with Apple Watch ultra.
For now, I'm getting used to the new system, but at first glance, my old Galaxy Watch 5 doesn't even stand up to the competition!
I feel like I finally have the right equipment, thank you Rob! 👍
You won’t regret it 👍🏻
Great review, thanks))) waiting for HUAWEI WATCH 4 review?
I don't want to be samsung biased but I have the watch as well as the huawei one and both the heart rate and the sleep tracking appear to be almost exactly the same when I tested the two during a workout sessions and in the morning for sleep. Maybe it depends on the person but for me I get very very similar results. For example the heart rate on the samsung now(when writing this comment) is 76, while the huawei is 77, the lowest and highest heartrates of the day are 44:140 and 44:139 and the sleep is 8h11m to 8h01. The max difference between steps at the end of the day is 200-250 with over 15,000 total steps. In conclusion during my testings the results are both mainly the same.
Thanks a lot for all your work. After watching about 15 videos and telling all my sport friends about your channel, which I had found on Reddit, I finally bought a watch for myself. No, it's not Galaxy. I decided to go for Huawei. I hope the 4-version will be as good as the previous one. I'm sure in a month or two there will be a review here, which we all look forward to! You are a hell of a man.
I can't believe you are just the only one on the whole Planet who did something that everyone needs and nobody thought of.
Thanks for the detailed testing of Galaxy Watch. Disappointing that Samsung still haven't figured out to get as accurate in readings as possible. This really stops me from buying Samsung phones as there's no point in paying same as Apple watch but getting a mediocre product. As always thanks for taking the time to test these watches and giving us the correct opinion before putting our money into them.
I literally won't buy a watch until Rob has released his review.
I can't think of anyone providing more reliable data
Still waiting for Huawei Watch 4 Pro review.
Great review once again! What about reviewing Ultrahuman Ring AIR at some point? Would be super interesting to see you compare it to the Oura ring 3
Thanks for the in-depth analysis. 👍I've used the Smartwatch 6 to track overall sleep time, the last couple of nights and to me it seems pretty accurate. I also fell asleep during the day yesterday, and it picked that up. I'm not so concerned about REM or light sleep, at the moment. Glad to see HR at rest, is overall accurate enough and blood-oxygen as well. When I exercise, I cycle outdoors and will not be wearing my watch for that. Don't want a tan line 😃, and don't need it. For GPS I have a Garmin and the app on my phone. Again, thanks. Look forward to any other updates.
ive been waiting for this
Thank you very much for your existence!!! As a man, who very deeply tries to find a right buy for myself, I spend a looot of time for searching and comparing things, to make a good/perfect decision. Your channel and work with independent review is a honey for me. Very structural, great graphics, great comparisons.
Because it's too hard to find a right gadget in this mess of them.
Thank you one more time!
I would like to see a number for the percentage of overall sleep stage agreement, not just a graph of the single (worst) and aveage percentage. Perhaps this could be added as a column in the agreement chart. Maybe, also, if your going to plot the worst, plot the best...
Also, mixing measurements from different references on the same chart would me much more useful if that chart included measurements from (at least) 1 reference device for every watch. Yes, this would mean multiple measurements (for a single watch) on the graph, but at least the data would have more relevance.
For me, the issue of accuracy isn't just relevant to the best available measurements but also relevant to other devices. When the graph plots points from different reference measuring devices, the relevance of the plot points can be lost (between some devices).
That said, I really appreciate your approach and testing. I find it extremely valuable even as is.
It's so wild and cool that the cheap chest strap out performs all the watches no matter how expensive.
it is specialiced to only do that, also taking measurements in the chest is way more constant than in the wrist.
That's like saying it's wild and cool that my simple, 15 year old speaker set has vastly better sound than my brand new phone
@@Alexchii I dont think thats too crazy
Was about to buy the Galaxy Watch 6 Classic. So glad I watched this before pulling the trigger. Going to wait for the Pixel Watch 2 as the Pixel Watch 1 appears to do much better than Samsung's efforts
Personally I will wait for next year as Samsung should release the Galaxy Watch 6 pro. Hopefully it will be a major upgrade ..
@@theophiledGood luck with that
@@theophiledIt's not their priority so nope.
@@theophiled don't hope, look Galaxy Watch 5 pro 😢
@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!
Great review! As a suggestion for devices that support it - would be good to do Blood Pressure & ECG tests as well. Keep up the good work!
Ty. I'll stick with my versa 2. It's great. Battery awesome, steps and heart rate good. Add polar strap and you get all you need
I was looking for this. Perfect. I'm shocked disappointed happy and excited. Really hope the new garmin watches can peak or match apples performance.
I dont know if I missed it, but how many nights of sleep tracking were tested? I've heard many say, that continuous use of the watch could improve the accuracy of that.
We are still waiting for HUAWEI WATCH 4 PRO scientific review!!
Brilliant review, as always. Thank you for your hard work, Rob.
I wasn't waiting for this actually but your presentation forces me to watch your reviews, doc
Do you plan to test the new huawei watches gen 4
Hi scientist! it would be really interesting to test these popular watches again after some time to see how software has improved/made them worse or model mumbers
was waiting for this and finally got my watch 6 classic as well. The results from previous review are still holding, including the R with POLAR, the inertia in catching up to changes. Idk if the performance merits the price tag, and Samsung probably knows it too, that's why all the deep discounts (got 30%+ discount myself). Just holding it for the sake of the "ecosystem", and it looks alright.
Love the video, still waiting for the ticwatch pro 5 review tho 👌💪
Nice vid as always. I got the Classic 4 for may mom 2m ago (needed some medical monitoring), I compared it to my Apple and I found it actually useless. When I saw the 6 and the "sponsored" propaganda, I thought it was going to be better.... Wish I had waited for your review before wasting more money in this brand. It's better than the E610 I got recently (for a fraction), that one I knew was going to be a wa$te, and this one is a bigger waste. Instead of these 2 I could have probably just waited one month and bought the next Apple Watch. Cheers and keep the good work- Vielen Dank.
Rob, please review the Huawei Watch D!!! Is measures blood pressure 😋
In every video I watched regarding this watch, I mentioned your channel saying how you test and compare these watches. I was counting on getting this watch, but after seeing your reviews, I shall wait yet another year. The most important features I look at are hr (daily use - not sports) general health tracking and sleep tracking.
I've read a few stories about the Apple watch saving lives, not so sure this watch will provide the same service.
Can you not contact Samsung and show them your results?
For me, personally I was so disappointed.
I was hoping you could do a review on the regular version the Galaxy watch 6 and see where that falls in line compared to the rest. I purchased both models pre-order and ended up keeping the regular and sending back the classic. This decision was partially made from watching your videos get the first reviewer who actually does real-world testing alongside a medical device can you please do a test with the regular Galaxy watch 6
To me, it looks as if the sensors have not been upgraded - at all.
Personally I am disappointed by Samsung, I would have expected better.
Nice smartwatch, mediocre health tracker: that's what I am taking from this.
Should I want to replace my Galaxy Watch 4 Classic I'll check out Garmin and Polar.
no kudos to Samsung this time.
The ECG works and is FDA certified. I've actually had really valuable use of it, so... it's a mixed bag and not a blanket statement. I'm living proof of it!
HRM isn't that bad either for regular stuff, like walking and steady state use. Bioimpedance is OK and they are alone in the Android market for this afaik. The disappointment to me is that their sleep algorithms don't seem to be improving, and they must have a huge database of users, and that Apple has shown what is possible in terms of accuracy...
@@GadgetyMV
Good.
I've decided to skip the Galaxy Watch 6 Classic ... I do want to see improvements on the health tracking front.
Improving sensors is not easy,
and there are tons of patents around it
and also around the algorithms that make sense of the signals those components deliver.
It is really costly, takes a lot of investments and payment of fees and royalties to third parties.
Samsung - from my perspective - stuck with what they already have and refrained from any investments re the health tracker functions.
They just added some cosmetic bells & whistles around the Smart Watch functionalities but left the core health tracking functions untouched.
That way Samsung ticked off some good old marketing check boxes at zero cost.
If Samsung continues this path (for cost reasons) it will continue to deliver a nice Smart Watch combined with stale health functions.
I am a Samsung fan but here I will part ways.

Please review the Huawei Watch D!!! Is measures blood pressure 😋
Samsung Galaxy Watch has some additional features that the competitors lack, for example, blood pressure and body composition measurements. You could test and include these metrics as well in the full review Rob. Anyway, it is a good review and we don't see much of an improvement on Samsung side with respect to previous generations. PS : Rob, you always say the heart rate measurements when biking outdoor are difficult due to the bumps in the roads. While it is true, do you ensure a firm contact of the watch with the skin during the entire trip ? I do it by tightening the watch strap and whenever it gets loose, I stop and readjust it.
It doesn't matter how many sensors the watch has if they are not accurate.
Others have tested the bioimpedance and compared it to DEXA. It was off about 20%, and varied between users. The variation within a user didn't seem that big. On me the variation isn't big, so it seems to track me well enough. What I do is take at least 5 measurements, remove the top and bottom one, and average the rest. That said, I'm very lean and I can track visually as well, and it seems to correspond well.
They can't even get the heart tracking right , I have little faith they can get other biometric data right disappointing
@@tthyssen Sensor galore. Samsung knows features sell. The average user might not know how accurate or inaccurate sensors are, and other aspects also influence the buying decision. Samsung is targeting the mass market. I believe the market also comprises those that buy data from Samsung, and it would be interesting to understand how the accuracy influences their decisions.
Just got my Watch 6 Classic, swapped my Watch 4 which was quite reliable, love the Classic watch 6 appearance. I've done a few exercises wearing both the 6 & 4, they give very similar readings. The watch 6 is good only because it's a newer device that's all, nothing else beyond that.
In terms of accuracy, I've come to accept that for watches acceptable accuracy is all that's needed, the GW is acceptable.
Acceptable is a hellish thing to say after spending $500 on a new watch
@@zemiguel2550 the alternatives have their own drawbacks so it ends up being a balancing act on user preferences.
I think that your tests are missing one very key test and that is a calorie count test. One that counts your whole day and one that counts only your workout. This is very important for me and for many people that workout and count calories.
In my testing done loong ago, Gear S3 from samsung failed horribly. They were basically making those numbers up and did not use the heart rate data to compute the calorie count, even during workouts. However, second gen of apple watch were already amazing at this, calculating quite accurately the amount of calories burned.
Please consider this as a new addition to your metrics.
Thanks.
Agreed. Calories burned is the no.1 most important feature of a smart watch that I want to be accurate.
Hey Rob, just wondering if you wear watches for a couple of weeks prior to doing the tests to allow it to "get to know" your body? I have read a lot of smart watches require this learning period before they start giving accurate data. Thank you so much for your videos, you are providing a public service!!
Hi! Usually I don’t have this time unfortunately. Sometimes I use an account where a previous watch from that brand was connected
14:03 wow! You got PewDiePie as guest star!
Great video as always!
I really appreciate your incredibly rigorous testing. Just got this watch, and as disappointing as it is to find out that its data collection is rather mediocre, at least I know not to put too much stock in it now.
I have a Galaxy 5 Pro, I am 56, a bit overweight, and have sleep apnea. I have worn this watch during three separate sleep studies, and for me it is far more accurate than what your test shows. My doctor was amazed how close it was around 85-90 percent for O2 and around 80% for sleep stages. That is the problem with this review, you really only have one data point. It is possible that companies like Apple calibrate their watch for younger fit individuals whereas companies like Samsung calibrate their devices for folks like me, I.E. the people that really need this type of data.
It would be far more valuable (and conclusive) if these devices could be tested on a wider range of individuals. How difficult would it be to partner up with a sleep study center and get people wear these watches at the same time? This good information, but it would be far more interesting than just testing on yourself.
I'm so gutted by these results! As a Samsung phone user, I so desperately want this watch for the eco system, all the apps and cool features...But what's the point if all the health and fitness tracking is so abysmally inaccurate?! (Which is the primary purpose of a watch for me). Bitter disappointment! Epic fail Samsung!
Hi Rob,
nice review as always!
I have a question.
It seems to me that the video shows the performance of the Galaxy Watch 6 Classic 43mm. Wouldn't the Galaxy Watch 6 Classic 47mm be worth trying too? Having a larger battery perhaps the algorithms could be slightly different. This would also explain the better performance of the Galaxy Watch 5 Pro. Thank you
Heavier watches seem to have worse HR measurement, and I wonder if the regular GW6 would measure HR more reliably than the GW6 Classic. However, spotty HR measurement is easily remedied by the ability to connect with a separate HR monitor, like the chest strap. I wish the GW's could do that natively. The ability to access other monitoring devices is a huge benefit of Garmins, for example.
I hope that #Samsung is watching this.... you guys a lot of work to do in the field of accuracy vs Apple watches
Feels like they're not putting any effort into accuracy as most reviewers only review features and cosmetic changes. Disappointing
@frooqy indeed. Most reviewers only check features and eye-candy screen and animations. Samsung should learn from Huawei and Apple for accuracy.
Supposedly they don't care cause they want to use the ring for more health accuracy
@@frooqyin fairness this isn't much deeper of a review. It's literally a sample size of 1.
Thank you! Super useful content as always
Would love to see you branch out into the smart scales
One day can you make data analysis fr huawei watch 4 pro.. thank you..
Ready appreciate such a detailed video. Could you please do it for Huawei watch 4 pro as well ?
Excellent video! Very valuable measurements and overview of results. Thanks for explaining so clearly. Would watch size be a significant variable to analyze? Not sure if the size would impact the contact of the sensor with the skin? Also, the band type/material may also impact the way the watch "slides" on the wrist.
I am happy with mine classic 6, switched from apple watch 5
Hello Rob,
Thank you very much for your excellent videos.
I would like you to test the huawei watch 4. I remember your test on the GT3 pro with good results except for sleep. I would like to buy a GT3 pro but maybe the huawei 4 is really better ? I need your tips. Thank you very mutch !
New to your channel and Thanks for sharing this information and all your hard work.💯✌️
Could you please test the Garmin 265?
The only review I care about
So i stick to my refurbished galaxy watch 4 classic and hope that the next pixel watch is actually an upgrade.
Please review Redmi Watch 3 Active😀😀😀
That's why I have often had a Garmin on one arm and a Galaxy Watch on the other when doing more serious fitness activities...they are okay for very casual use but are a far cry from professional grade. I still bought a Watch 6 though...but it was 50% off with my Z Fold 5!
It's interesting there are big differences in measures between Galaxy 4, 5 and 6 on the other side. Great videos as always!!! Also, you are intelligent to point about personal differences at the end of your videos and that points me to a personal question I hope you can answer, what is your height and weight? Best regards.
Why is Polar our standard? Isn't there another device to compare our numbers with? Like a control group
Honestly this tech is still in its early stages. Give it another decade or so.
Great video, thanks! Maybe it would be helpful to compare chest straps at some point. I have a PowrLabs that seems pretty accurate compared to my pulse oximeter. I decided to get a Garmin HRM Pro Plus to go with my Garmin watch and get extra walking /running info but had a lot of trouble with HR accuracy compared to the pulse oximeter. The conductive electrodes on the Garmin didn't seem to get a reliable signal from my skin and would put out readings that were off. I finally returned it. Maybe I'll try the Polar strap next.
Excellent video Rob. Does anyone know if software updates have fixed the issues? I have Watch 4 now and was looking a upgrading but after watching a few videos on the different brands, looks like Apple is best in class.
That's a great video. There's one thing though, that makes me wonder. Watch 4/5/6 normal/pro/classic all have the same(!) main sensors. So why do they differ so much. In at least one graph same goes to Apple Watch Ultra compared to other sensorwise similar Apple watches.
I guess it's either statistics, differenzt wear positions at wrist or newer software. Would be interesting to verify that by choosing an older watch again if it reacts differently now I.e. similar to the latest model.
I have been sleeping for some nights with both the 5PRO and the 6 Class, swapping from left to right in between the nights. The sleep tracking results differ majorly between the two. The only thing they agree about is the end time of the sleep. There IS a difference between the software of the two; I have pursosly not updated the PRO 5 to the latest version (which would bring it to the same version as the 6 class.
@@masterrobin3176 That's interesting. Thx
I love your videos. Thanks to you I got the Huawei GT Runner ❤
I would like to see you maybe do a re-review of r watches after a few firmware updates to see if they improve or get worse after an update
Hello, will u review new Huawei?
Hello, thankyou for checking this smartwatch into depth. I got an question, would the update of week 35 so last week of august, improve it? They said its stable, and not in beta anymore for Galaxy watch 4-5. Only America-Korea has the beta still.
Your reviews are awesome! I really like the data based comparisons although this doesn't make my search for a good watch easier. Nothing to with your amazing videos but there seem to be a big difference between apple products and 'the rest'. Or did i miss on? Is there an android watch with: hr sb/ob/wl aver. r: 0,9+ sleep match aver. 80%+ with rem 60%+
Did you skip over the graphs with other watches? Huawei is basically on par with Apple.
@@eddiev.261true for hr, but at sleep tracking they really suck and for me both aspects are important.
Thanks for the rigor you put into these reviews, could I request a device to be reviewed? The Redmi Watch 3 Active looks like a very interesting little device
I'm not surprised that there are some discrepancies in sleep stage tracking. I wonder if these smart watches are using PAT to produce an estimate. The doctor, who provided the research for home sleep tests for OSA was the former CEO of the company that pioneered the devices. He then sold his company to ResMed, who happens to be a diamond donor to the organization who published the scholarly journal. Home PAT tests were classified as "Technically acceptable." While they achieved diagnostic congruence with a PSG for severe OSA about 67% of the time, mild or moderate congruence was significantly less. Bottom line, if even a medical device misses almost a third of the time, consumer devices are at best giving you a ball park estimate and is best used to measure trend data over time instead of trying to use it as a medical device.

Wow so fast with the reviews ❤
Hi Rob!
Due to the bad results of the SW6 is it a sensor problem or software and algorithms?
If software issue, can it be solved in the future?
Thanks for the great review 🙌
This a question that is asked every time that new Samsung watch is released and there is always someone in the comments saying that accuracy will improve in the next few software updates... but it never did for any previous Galaxy watches afaik. So, you can risk it and hope that it happens this time, but probably it will not.
@Genial1990 Thank you for the satisfying answer 😁 I bought the classic version 47, I've been using it for about 10 days now but I will send it back today, and I will buy iphone 15 with apple watch. I will try it with apple this time, hope I won't regret it.

Hey, Rob! It would be really interesting if you compared the sleep tracking of garmin watches to the firstbeat bodyguard 2 or 3. Garmins algorithm is actually made for firstbeats bodyguard, so if you compare them you can see if it's the algorithm itself that is bad, or if it's Garmins watches that just don't work well with it.
I can't wait until the arrival of my Watch 6 Classic to maximize my Samsung ecosystem to guage my exercise performance output and easily make adjustments along my way w/ my Z Fold 5.
I just bought a 4 classic and I'm glad I did.
