fun fact verizon does not have the galaxy 7 lte in there system so they can not activate early arrivals Pinned by The Quantified Scientist @TheQuantifiedScientist
Hi. I have a question. Does the strap quality on the H10 Polar make a difference. E.g. original vs cheap knockoffs on amazon. I'm hoping you can help me with this. Thank you in advance
We all prey you're not blind and deaf... because problems are obvious and why most of the competitors have better algorithms than you, that a question...
I intentionally held off on pre-ordering. I needed to watch this video before I made my decision to buy or not, and I'm glad I did. I love Samsung phones, it's disappointing that they can't seem to get it right when it comes to their fitness tracking, but we'll have to wait and see if these watches get updates that fix these issues.
Honestly, this is a problem with testing and large sample sizes in dynamic environments. It feels like the Samsung CEO just tests these watches on his drive to work On only himself
@@codebraker12The Pixel watch is also more accurate than the Samsung Galaxy watch. What's the point of having more sensors if they are still far from being among the best? 🤷🏻♂️
@TheQuantifiedScientist Yes. Some signs of improvement but hopefully should turnout much better with some firware updates. My hope is on the new sensors and it's just how Samsung would use algorithms to make it as accurate as possible within the gamut of wearables. Will wait for your detailed review. Thanks
@@tibsyy895 Minor changes could be due to how the watch is worn and also if the algorithms could be slightly different considering few additional features in Ultra.
@@TheQuantifiedScientist cant wait to see how the samsung ring works with galaxy watch 7/ultra. They claimed that they work together for better accuracy, but i highly doubt that as always from samsung
Every year we get excited by Samsungs new wearbale thinking this is the year they get their health tracking right then we find out its just the same old issues on a newer more expensive device.
theyre limited by their measure methods they can use as a watch. also theres anatomical differences. i got a big ass vein at the place where they measure, so mine will be more accurate than someone who doesnt have that. but that only applies to blood related measurements. also no device like this or bathroom weight measures body composition well. cause this method, in general have severe flaws that makes it inaccurate.
In developer mode you can select 'force full GNSS measurements' which should improve GPS measurements but with a higher load on the battery. Could be interested to have this testet in the full review
Thanks Rob! Nice to see a preliminary clinical test so quickly on these highly anticipated watches. Looking forward to full testing. Super excited for upcoming Pixel devices.
I strictly use the watch 7 (previously 5) for sleep tracking and this makes me wonder if it's a software issue. Which although not good, suggests it could be improved on without new hardware. Videos like this help bring awareness. Thank you for this data collection and analysis. I hope Samsung is working on this
I am looking forward to your review on Galaxy ring. I LOVE what I see right now especially sleep tracking but I'd love to see the comparison between ring and your dedicated devices! Thank you!
It might be worthwhile for you (and other people commenting) to take a look past Mr Horst’s results at other published Galaxy watch studies ( of which there are many), which typically involve far more participants. And as regards heart rate accuracy, I also have two chest worn HRM’s and found a much closer agreement between them and my Watch 5, than demonstrated in the video. A quick online search got me to the following four studies (the titles are in quotation marks). Galaxy Watch 4 Bioelectrical Impedance Analysis (BIA) measurement showed a 97-98% correlation with the two reference devices. "Next-generation smart watches to estimate whole-body composition using bioimpedance analysis: accuracy and precision in a diverse, multiethnic sample - The American Journal of Clinical Nutrition" Galaxy Watch 5 ranked 2nd out of 11 consumer sleep trackers "Accuracy of 11 Wearable, Nearable, and Airable Consumer Sleep Trackers: Prospective Multicenter Validation Study - PubMed (nih.gov)" Study characterizing the performance of the Galaxy Watch 4 when measuring the estimated SpO2 during sleep. The accuracy of the GW4 complies with the FDA and ISO standards. "Performance evaluation of a wrist-worn reflectance pulse oximeter during sleep - Sleep Health: Journal of the National Sleep Foundation (sleephealthjournal.org)" The Samsung smartwatch provides acceptable HR, time-domain HRV, LF, and HF parameters during sleep time. In contrast, during the awake time, AVNN and HR show satisfactory accuracy, and the other HRV parameters have high errors. "A comprehensive accuracy assessment of Samsung smartwatch heart rate and heart rate variability - PMC (nih.gov)"
Thank you very much for the video. I was expecting the sleep reading values to be closer between devices. Was thinking of getting the Watch 7 but I may need to reconsider
I know some of these stats seem to be a bit inaccurate, but look at how accurtae they are as a whole. I mean if your like most runners and run 3-5 miles, a few times week, the distance will be within 0.1 miles of your milage ran, pretty great. Same for the HR tracking, most people use HR when doing steady state Zone 2 cardio, trying to stay within a certian area, these watches will achieve that.
I think most people are disappointed with the results compared to other brand watches, Samsung needs to do better, even Google has came closer in accuracy than Samsung.
@@MrSecretwest I agree, I'm also disappointed, but I'm just trying to make a point that even though these are not the most accurate, they are definitely accurate enough for most people, outside of serious athletes. With that being said, I have a hard time paying this much when I can get a Garmin Forerunner 965 or Garmin Venu 3 that is more accurate and has 90% of the smart watch capability, with 1-2 weeks of battery life.
I used all three, Garmin, Apple and Samsung, Samsung isn't even close to the other two for results. Samsung watch told me I only burned 200 calories for a 5k run, the other two had me closer to 500. Forget any type of weightlifting metrics, not even close to having any type of recorded workout. I can understand a small percentage here and there but Galaxy watches are super unreliable especially when you start hitting 10k runs or rucks.
I think most people seem to have forgotten that these watches are not suppose to be as accurate as actual medical devices. If you read the packaging it makes this point very clear.
Great video. Disappointed with the results for the two watches. What I look for in a watch is: 1. Android (not an Apple user) 2. 7 to 10-day battery life (so even if I was an Apple user, I wouldn't like to use Apple watches) 3. Great heart rate measurement and sleep tracking (don't care about GPS) 4. Form factor of a regular watch (round screen, big enough for my wrist - don't like smart bands or rings). It seems to me that, as of today, there are no options available in the market that fit all 4 criteria. Garmin Venu 3 is the closest, but even that is a bit too far from the top of sleep trackers for my taste.
@@danielmoksmann5654 you'll be waiting for a while and probably after Apple has achieved it. Until then you're just asking for a fitness tracker, any cheap one will do.
@@superiortoall22 As I said, the Garmin Venu 3 is the closest to what I want - don't really care about the Fitbits or other fitness trackers, it needs to look like a regular watch.
Great video as always! I'd love for you to delve into the alleged synergy between the galaxy watches and the galaxy ring. The combination supposedly makes the measurements more accurate and makes the devices' batteries last longer.
I already bought it trading 5 pro. I'm only going to use it for outdoor cycling, hiking, and running. I'm disappointed that accuracy is still the same. This means the spare is at fault. I hope they tweak the software, but I'm not going to update again unless they drastically improve the accuracy. Even 5 pro is good enough if i hadn't updated.
I think you need a larger control group, there's a lot of factors at play that are unique to you and how the sensors interact with you, you would establish a better average using a larger control group across say 3 people at least
Great analytics. I heard from other sources too that it was not great. Your recommended videos to watch was not on the screen. Keep up the great work...
It's very interesting how differently the Galaxy Watch 7 and Galaxy Watch 7 Ultra do on the GPS test. I wonder if the larger Ultra has a different antenna design than the regular watch and that is the cause of the difference? It also makes me wonder if the larger 44mm Galaxy Watch 7 behaves more like the 40mm or the larger Ultra watch?
Thank you for test. After watching your channel, 5 days ago, I cancelled my Samsung 7 ultra watch preorder. I still have the 5 pro though but thinking to move away from Samsung due to GPS system inaccuracy as well as sleep tracking.
It seems like Samsung still hasn't figured it out. I pre-ordered it, and it arrived yesterday. I've noticed changes in heart rate tracking, but I wasn't certain until I saw this review.
Is it a big deal for you though or can it be negligible. Thinking of getting a smartwatch. I do want good fitness, sleep and heart rate. I can ignore if its not fully accurate. I would look for 85% plus accuracy though. Maybe 80%
Thanks for your super review. I'm quite sure the firmware is not mature yet. Till we don't see any update on the software, it is difficult to apprehend the results of new sensors with an unadapted software. So let's see in the future. Regarding body composition, I've a galaxy watch pro 5 that I compare with an inbody scale with their own BIA sensors and the watch consistently over estimate my body fat compared to the 8 electrodes scale (about 2 to 3 points more on the watch). Look forward to seeing more of your tests ! Vielen danke!
Rob, absolutely amazing analysis. As a fellow Engineer and Bodybuilder I commend you on the work that you consistently do. I've also been consistently using Samsung devices since 2014 and after the abysmal performance metrics you showcased with the Galaxy Watch 6 I almost jumped ship - but I stuck it out....but I'm hanging on a thread and now realizing I may jump off. With that out of the way - what do you recommend from all your previous testing that is the best SMARTWATCH for WEIGHT LIFTING only? Thank you for your time and keep up the ultra informative work you are doing! Godspeed!
If you don't mind being closed off in Apple, then yeah the Apple watch. I use it for weightlifting and honestly, flying, to measure my vitals taking Gs.
I already said it about the watch 7. Samsung has the technological capabilities to do much better. They get away with this crap as apparently the consumer demand does not force them to produce better quality.
Thank you for this comparison. I'm not interested in Samsung watches since they've historically been worse at health tracking than their similarly priced competition, but it's always a relaxing (and an inspiring) experience to see your diligent efforts.
Hey Rob, thanks for testing and sharing the results so swiftly! I adore your work just because you are doing a great job keeping it as scientific as it can be! Looking forward seeing your next videos before I purchase the Galaxy Watch 7!
Also, on the sensor testing I would definitely redo this comparison in like 2 months to see what things look like with fully ironed out software. 🤷 Products like these are absolutely NOTORIOUS for coming in hot on the software development front right at the inital launch before ironing out the missed major issues with the first couple major software updates. But if things are still just as inconsistent a few months from now, then we sadly have ourselves something of a very legitimate problem. Although the fact that it already CAN function accurately & consistently outdoors (aka the hardest conditions for a light based sensor) that means the new sensor hardware itself IS good enough and it should be able to be fixed to work just as well indoors simply with software updates. 🤷
@@TheQuantifiedScientist Considering the outdoors during peak summer sun results (again, by FAAAAAAAR the hardest environment for any visible/IR light based sensor!), I'm more than fairly confident than the GW7/Ultra's brand new sensor suite legitimately does have the horses for courses on a hardware level. The inconsistencies only being found when indoors really just seem to just be a software optimization issue, not a deficient hardware capabilities one. 🤷 That said, how long it takes Samsung to actually fix these software optimization problems with the new sensor via updates though is a whole different kettle of fish. Here's hoping it's sooner rather than later! If they can fix these sensor inconsistencies though, Samsung will have a MASSIVE winner on their hands with just how INSANELY FAST & FAR AHEAD OF THE COMPETITION (even Apple!!!) the new 3nm Exynos W1000 is in therms of smartwatch SOC performance! ESPECIALLY when you consider the fact that it (Exynos W1000) &/or slightly tweaked derivatives of it (think GW6's slightly higher clocked W930 vs the GW4/5's OG W920) are likely to be used in the next ≈2-3x generations of Galaxy Watch, meaning NOW is the time to upgrade for peak longevity!
@@edderepa9685 ... Except that the tracking is ALREADY dramatically better and more accurate than it was at launch! 🤷 (Which again, the hardware ALWAYS had the potential to do, as it was ALREADY shockingly accurate outdoors in vastly more messy & complicated lighting conditions). Same with the infamous battery life drain problem being essentially fixed as well. The notority and media presence of the Galaxy Watch Ultra (not to mention its absolutely HUUUUUUUGE profit margins) has helped SIGNIFICANTLY with Samsung actually putting in the post-launch legwork for this generation of WearOS hardware, when as you bring up they very much haven't always done so.
If you need accurate heart rate reading just get a heart rate monitor band.... If you want a perfect GPS reading then get a "proper training watch" .. Garmin, suunto, coros watch will give you all you want...
Awesome review of the Samsung Watch 7 and Ultra! As a big fan of Samsung, I'm really interested in how the Apple Watch Ultra compares in terms of accuracy. It would be great to see a comparison with it since many people claim it’s more accurate.
Waiting for the full review. Maybe some firmware and software updates. But tbh, I'm not holding my breath. It's good to see that they've improved over the previous generation, but still not as consistent as the Apple Watch 9. Which is SAD because I daily Android.
It seems UI 7 is about to be launched in August, and maybe it will improve measurements. I received the 7 Ultra yesterday, and I see no big differences with the 5 pro I had. Same issue on body composition vs an "8 electrodes/2 different currents" scale (the watch recognizes a part of the skeletic muscle as body fat ~2%). Also a bad measurement during a cycle training yesterday which stopped at 5min (didn't notice until I finished. Maybe I've done something wrong?) It has never happened with the 5 pro. GPS is ok. That's why I strongly think a software improvement is on the way as they cannot keep these "average" measurement though they have top notch hardware.
Yes, but they are so pretty close with their results so you can call them even. The more interesting thing is that how even old Apple Watch is far better than newest Samsung watches… 😮
Awesome video! Would love to see one about the sleep tracking of different wearable rings if possible 🙏 (Oura, Ultrahuman, Ringconn, Galaxy Ring, ETC.)
Keep in mind that most of the people complaining about the battery, didn't even let the watch learn your usage pattern. I'm using my Watch 7 for about 2 weeks, and clearly noticed that after the initial learning, it got much better. I had a 5 Pro, the battery life is not as good, but the advantages compensate this factor. I'm getting around 2 days battery life, with AOD, sleep monitoring and some exercises. With 10w charging, shower time + dinner time is more than enough for daily usage.
Thanks a lot for this @Rob! It's still sad to see other watches like the Google Pixel Watch 2 and Huawei watches doing much better than the Galaxy watches even with an updated sensor. I hope this changes as the watch adapts to your workouts when the full review comes out or through updates. So far I'm sticking to my watch6 because I'm not convinced of that it's worth the upgrade. Cheers and grateful for your reviews 🙏🏽

I'm greatly looking forward to the full review. Do you have any idea when you will post it? I imagine they take a while to make.
Thank you for test. After watching your channel, 5 days ago, I cancelled my Samsung 7 ultra watch preorder. I still have the 5 pro though but thinking to move away from Samsung due to GPS system inaccuracy as well as sleep tracking.
first time watching your videos, this definitely has helped weigh in to my decision on purchasing.
I have been waiting for this.
It seems like Samsung still hasn't figured it out.
I pre-ordered it, and it arrived yesterday. I've noticed changes in heart rate tracking, but I wasn't certain until I saw this review.
Is it a big deal for you though or can it be negligible. Thinking of getting a smartwatch. I do want good fitness, sleep and heart rate. I can ignore if its not fully accurate. I would look for 85% plus accuracy though. Maybe 80%
Thanks for your super review. I'm quite sure the firmware is not mature yet.
Till we don't see any update on the software, it is difficult to apprehend the results of new sensors with an unadapted software.
So let's see in the future.
Regarding body composition, I've a galaxy watch pro 5 that I compare with an inbody scale with their own BIA sensors and the watch consistently over estimate my body fat compared to the 8 electrodes scale (about 2 to 3 points more on the watch).
Look forward to seeing more of your tests !
Vielen danke!
Rob, absolutely amazing analysis. As a fellow Engineer and Bodybuilder I commend you on the work that you consistently do. I've also been consistently using Samsung devices since 2014 and after the abysmal performance metrics you showcased with the Galaxy Watch 6 I almost jumped ship - but I stuck it out....but I'm hanging on a thread and now realizing I may jump off. With that out of the way - what do you recommend from all your previous testing that is the best SMARTWATCH for WEIGHT LIFTING only? Thank you for your time and keep up the ultra informative work you are doing! Godspeed!
Use any Apple Watch after 6 series and you will be ok with it. Samsung HR measurements are just inaccurate
If you don't mind being closed off in Apple, then yeah the Apple watch. I use it for weightlifting and honestly, flying, to measure my vitals taking Gs.
Brilliant video, so informative and love the extensive data points :)
Glad you enjoyed it!
Well, this video just saved me $650....thanks Rob
The video I've been waiting for. Cheers!
I already said it about the watch 7. Samsung has the technological capabilities to do much better. They get away with this crap as apparently the consumer demand does not force them to produce better quality.
Thank you Rob! Just what I was waiting for.... Now it is decision time -stay or go.... Keep up the much appreciated work!!
Impressive video and data comparisons! Definitely going to subscribe
Thanks for you extensive and honest review!
Thanks for the video! Best science channel 😎. Every watch i ever had, i came here first to check the review
Thank you for this comparison. I'm not interested in Samsung watches since they've historically been worse at health tracking than their similarly priced competition, but it's always a relaxing (and an inspiring) experience to see your diligent efforts.
Hey Rob, thanks for testing and sharing the results so swiftly! I adore your work just because you are doing a great job keeping it as scientific as it can be!
Looking forward seeing your next videos before I purchase the Galaxy Watch 7!
Great review would love to see the results/comparison of previous galaxy watches.
Your channel is a gem!
Great job man! Thanks for such a great content!
Also, on the sensor testing I would definitely redo this comparison in like 2 months to see what things look like with fully ironed out software. 🤷
Products like these are absolutely NOTORIOUS for coming in hot on the software development front right at the inital launch before ironing out the missed major issues with the first couple major software updates.
But if things are still just as inconsistent a few months from now, then we sadly have ourselves something of a very legitimate problem. Although the fact that it already CAN function accurately & consistently outdoors (aka the hardest conditions for a light based sensor) that means the new sensor hardware itself IS good enough and it should be able to be fixed to work just as well indoors simply with software updates. 🤷
Makes total sense to redo the testing later (and also more testing now). Thanks for sharing!
@@TheQuantifiedScientist Considering the outdoors during peak summer sun results (again, by FAAAAAAAR the hardest environment for any visible/IR light based sensor!), I'm more than fairly confident than the GW7/Ultra's brand new sensor suite legitimately does have the horses for courses on a hardware level. The inconsistencies only being found when indoors really just seem to just be a software optimization issue, not a deficient hardware capabilities one. 🤷
That said, how long it takes Samsung to actually fix these software optimization problems with the new sensor via updates though is a whole different kettle of fish. Here's hoping it's sooner rather than later!
If they can fix these sensor inconsistencies though, Samsung will have a MASSIVE winner on their hands with just how INSANELY FAST & FAR AHEAD OF THE COMPETITION (even Apple!!!) the new 3nm Exynos W1000 is in therms of smartwatch SOC performance!
ESPECIALLY when you consider the fact that it (Exynos W1000) &/or slightly tweaked derivatives of it (think GW6's slightly higher clocked W930 vs the GW4/5's OG W920) are likely to be used in the next ≈2-3x generations of Galaxy Watch, meaning NOW is the time to upgrade for peak longevity!
Like DC Rainmaker says, with every generation of Samsung watches there is the same "they will fix it with software" cope and they never do
@@edderepa9685 ... Except that the tracking is ALREADY dramatically better and more accurate than it was at launch! 🤷 (Which again, the hardware ALWAYS had the potential to do, as it was ALREADY shockingly accurate outdoors in vastly more messy & complicated lighting conditions). Same with the infamous battery life drain problem being essentially fixed as well.
The notority and media presence of the Galaxy Watch Ultra (not to mention its absolutely HUUUUUUUGE profit margins) has helped SIGNIFICANTLY with Samsung actually putting in the post-launch legwork for this generation of WearOS hardware, when as you bring up they very much haven't always done so.
Awesome review, as always. I'm impressed about the blood pressure sensors. Only that 😅
If you need accurate heart rate reading just get a heart rate monitor band.... If you want a perfect GPS reading then get a "proper training watch" .. Garmin, suunto, coros watch will give you all you want...
Yeah~~~~ Your are back with Galaxy watch 7!!!!!!
Awesome review of the Samsung Watch 7 and Ultra! As a big fan of Samsung, I'm really interested in how the Apple Watch Ultra compares in terms of accuracy. It would be great to see a comparison with it since many people claim it’s more accurate.
Thanks, I always refer to your videos for the new smartwatches , rock on!
Waiting for the full review. Maybe some firmware and software updates. But tbh, I'm not holding my breath. It's good to see that they've improved over the previous generation, but still not as consistent as the Apple Watch 9. Which is SAD because I daily Android.
It seems UI 7 is about to be launched in August, and maybe it will improve measurements.
I received the 7 Ultra yesterday, and I see no big differences with the 5 pro I had.
Same issue on body composition vs an "8 electrodes/2 different currents" scale (the watch recognizes a part of the skeletic muscle as body fat ~2%).
Also a bad measurement during a cycle training yesterday which stopped at 5min (didn't notice until I finished. Maybe I've done something wrong?) It has never happened with the 5 pro.
GPS is ok.
That's why I strongly think a software improvement is on the way as they cannot keep these "average" measurement though they have top notch hardware.
@@slim1857 Exactly. They need to improve this ASAP. Apple has been measuring accurately for years now.
@@costafilh0 I also hope they will improve it ! If Huawei is able to do it, Samsung MUST address this.
@@slim1857 Yes! Yes!
I cant wait for you to review the galaxy ring !! I wont buy another samsung health tracker without watching your videos.
I was waiting for it !! Thank you !!!
No problem!!
You're the best!! Im definitely going to buy this one and give my pw2 away. Have a good one sir!
I love your review. Please keep it up!
I was eagerly waiting for this from you. Thanks for the upload!
What kills me is the first HR chart. The top 5 being Apple Watch (AW)SE2022>AW9>AW6>AW7 THEN the Ultras?…
Yes, but they are so pretty close with their results so you can call them even. The more interesting thing is that how even old Apple Watch is far better than newest Samsung watches… 😮
Because of the shape and bulk, also there is huawei watch gt3 pro in between they make really accurate watches with insane battery life
@@keepsoulfree Yes!
Thank you for all the work you put into these videos!
good video, hope you will be getting around to the galaxy ring VERY soon :)
Awesome video! Would love to see one about the sleep tracking of different wearable rings if possible 🙏 (Oura, Ultrahuman, Ringconn, Galaxy Ring, ETC.)
I ve been waiting for this video for soooo lonng ❤
Well done as always mate- keep them honest!!
Dang a galaxy watch review before a scanwatch 2 review. RIP. But solid review, was considering these as well, but the battery is what pulls me away
Keep in mind that most of the people complaining about the battery, didn't even let the watch learn your usage pattern. I'm using my Watch 7 for about 2 weeks, and clearly noticed that after the initial learning, it got much better. I had a 5 Pro, the battery life is not as good, but the advantages compensate this factor. I'm getting around 2 days battery life, with AOD, sleep monitoring and some exercises. With 10w charging, shower time + dinner time is more than enough for daily usage.
Im so happy i found this channel, very informative! Can't wait for the galaxy ring test!
Great analysis!
Thanks a lot for this @Rob! It's still sad to see other watches like the Google Pixel Watch 2 and Huawei watches doing much better than the Galaxy watches even with an updated sensor.
I hope this changes as the watch adapts to your workouts when the full review comes out or through updates. So far I'm sticking to my watch6 because I'm not convinced of that it's worth the upgrade.
Cheers and grateful for your reviews 🙏🏽
Great video. Decision made, waiting for the Galaxy Ring review. Thanks
That's the review I was waiting for!!!
I've been waiting for your review before purchasing the GWU. Was hoping for better results. Looking forward to seeing the Galaxy Ring
Great review rob! Thanks!
Thanks!!
