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...
@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.
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? 🤷🏻♂️
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)"
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.
@@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
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
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!
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.
@slim1857 they should've honestly putted better sensor in the ultra or they shouldn't have putted the new sensor on the watch 7 to make it more ultra, I'd say they upgrade the watch 7 a bit too much.
@@Shan_Shah this is for industrial purposes, like scale savings. For a new chip this is not unusual. They still could deactivate some functionalities as they do on computers for example. But you are right. The 2 models are close.
@slim1857 the ultra atleast should've gotten the same heart rate sensor as the apple watch, like what is the point of giving up wireless charging for this new sensor considering it's not that much better than it's predecessors.
Maybe a good comparison is the initial test vs. the tests of all the devices to compare software maturity, or we wait for the long term comparison...also, why no running on the tests?
The graph comparing multiple smartwatches seems to have made an accurate comparison but it is not so. This is because all watches were not tested with the same protocol and performed the same exercise at the same time zone. It makes no sense to believe this data as the subject pool was actually one person. Measuring ppg signals requires a sample size of over 100 people for basic comparisons.
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%
I wonder what's making it impossible for them to achieve a similar performance to the apple watch or some of the best Huawei watches when it comes to the HR sensor.
Most people are not professional athletes. They will never fully use these health tracking features. Samsung unders this well that is why they don't waste resources on this. If you want an accurate reading, go to a hospital and use proper medical equipment.
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 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
Will this be good for Gym workouts tracking and general health trackings as i only have a samsung device and don't have much time left because the offers ends 😢
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… 😮
Is there any improvement with the Galaxy 6 Classic? (Health wise, heart tracking just for the regular things, as walking or sitting, and Sleeping tracking). Would love a reply.
@TheQuantifiedScientist I own and use at the moment: 1. Apple Watch SE (2022). 2. Fitbit Sense 2. I want to buy a replacement watch for Fitbit Sense 2 to connect to my Samsung Galaxy S23 Ultra. What choices I have ? I was thinking for Polar Ignite 3 or Google Pixel or Samsung Watch 7 ?
Also the pixel watch 3 is coming out in 3 weeks, you could wait for the review but the 2 is already more accurate than any galaxy watch. Also Polar make good heart tracking devices but their watches are super inaccurate
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!
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 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 love these videos and truly appreciate all the hardworking that goes into these. These comparisons are freaking amazing. Thank you so much for your time
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.
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.
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...
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.
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.
I am wondering the same question. Due to difference in battery size, and L1+L5 mode probably more battery consuming than L1 only, maybe the Watch 7 40/44 mm defaut setting is different from Watch 7 Ultra defaut setting, regarding GPS tracking precision.
www.youtube.com/@TheQuantifiedScientist Could you please give the setup of both your Galaxy Watch 7 40 mm and your Galaxy Watch 7 Ultra, during the GPS tests, regarding the GPS accuracy tracking ?
Wow, so disappointing. I own a PW1 which has performed brilliantly but I wanted a 2nd device. The previous time I tried a GW was the 5-series and that went back in under a week because the GPS accuracy was so incredibly bad. I thought for sure this would be the one but apparently not. Thanks for getting this out as quickly as you did, Rob.
This chart makes me think the galaxy watch is doing too much averaging in software. That would help explain the delay compared to the H10 and the fact that it misses short HR dips. The good news is that can be resolved in software updates. Then again, your correlation charts indicate why they're using so much software averaging. The GPS data is certainly interesting considering the phones share the same hardware so you would think the only difference might be some layout changes. I wouldn't think you would see this much of it difference in GPS performance. This makes me think the 7 is making some GPS compromises in software to improve battery life. It would be pretty unfortunate to find out the 7 derates performance in software just to make the Ultra stand out as the better device.
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!
Oh yes, been waiting for this! The new BioActive sensor didn't seem to improve the results... A disappointment. As for the Ultra being better for GPS, I'm wondering if its larger battery means programming has been tuned to poll more frequently? The body impedance measurement... if true [it's not], 2.9%, you'd have very low testosterone levels, and over time become depressive, probably. I usually take 5 or 10 measurements in a row and calculate an average because they vary somewhat. They seem to be very sensitive to how the fingers are placed on the two button sensors, also tightening the strap, and placing the watch a bit higher up on the arm. When you do gym testing, please consider testing the rep counting, too. I wish Samsung released access to this for external apps. It used to be part of all Wear OS watches in Google Fit, until Samsung entered the scene. Unless there's review data out there, I believe Samsung will rest on their laurels for this particular feature in terms of where they allocate their development resources. Looking forward to the follow up.
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.
You had me at the start there. It looked like Samsung had turned a corner and finally made an accurate watch but as the video progressed it became evident that it’s just as bad or worse than previous Samsung watches 😅

@@keepsoulfree Yes!
Awesome video, and I also liked the new format with the portable mic. Not so happy with results though. Thanks for the videos.
Is there any improvement with the Galaxy 6 Classic? (Health wise, heart tracking just for the regular things, as walking or sitting, and Sleeping tracking).
Would love a reply.
do you think software upadates can fix these problems with sleep detection?
I wanted to know that too.
They could but they won't
No
@TheQuantifiedScientist
I own and use at the moment:
1. Apple Watch SE (2022).
2. Fitbit Sense 2.
I want to buy a replacement watch for Fitbit Sense 2 to connect to my Samsung Galaxy S23 Ultra.
What choices I have ?
I was thinking for Polar Ignite 3 or Google Pixel or Samsung Watch 7 ?
Also the pixel watch 3 is coming out in 3 weeks, you could wait for the review but the 2 is already more accurate than any galaxy watch.
Also Polar make good heart tracking devices but their watches are super inaccurate
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!
Will do!
Thanks for an excellent review as always. Looking forward to you getting your hands on the pixel watch 3.
You and me both! So far no-one has reached out
@@TheQuantifiedScientist will you get the 41mm or the 45mm ?
Its been years that I watched you the first time and I see, you are still awesome. Still the same incredible quality. Thank you :)
Thank you. You just saved me from an unnecessary preorder. Will be sticking to my watch 6 classic.
Thank you for the review! The best channel for any wearable devices ! Recomended!
What about AGEs index??
Thank you very much mate, will be happy to see CMF Watch Pro 2, hope it's better than 1 product.
I was waiting for it !! Thank you !!!
No problem!!
Crazy good testing and also results within the first few days of release. Awesome and really useful content
Amazing content op. Hats off. I'm glad i at least found your channel now.
Welcome aboard! ;-)
Wow! Amazing video with lots of data - I love it!
Gonna link to this video in my review of the Galaxy Watch Ultra!
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.
@@sethdbrown30 these Samsung watches are okay for moderate health features and great for notifications and Samsung phone integration
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.
Fantastic - excited for my 44mm 7. These seem to be the most promising GW results yet. Thanks for your hsrd work to get these initial results out
You are very welcome!
Is this done? Or are you still collecting data?
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.
No Spo2 test? Can it measure Spo2 continously or does it measure it only on demand like having to manualy launch Spo2 check?
It measures continuously if you want it to.
@@mightypine thank you
@@mightypineNo it doesn’t measure continuously until while sleeping. For rest of the time you can measure manually
I love these videos and truly appreciate all the hardworking that goes into these. These comparisons are freaking amazing. Thank you so much for your time
The lack of fitness tracking accuracy on the Samsung wearables is the reason I am jumping ship back to Apple when the new iPhone 16 comes out.
can you test AGEs Index?
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.
But Garmin has shitty app store
So you just want a fitness tracker, no watch with WearOS is going to give you 7-10 days of battery life.
@@superiortoall22 Yet.
@@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.
Thank you. I was really hoping that Samsung improved their sensors to match Apple.
I was eagerly waiting for this from you. Thanks for the upload!
Finallyyyyy thank you thank you thank you thank you 🎉🎉🎉🎉 keep up the great work
You're welcome!! ☺️
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.
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...
Review out before the extra pre order credits expire.... god tier!
Impressive video and data comparisons! Definitely going to subscribe
Great overview, I appreciate all the testing and stats, and repeating same stories like a lot of other reviews do. Thanks!!!
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.
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!
The Definitive Review I was waiting for
The video I've been waiting for. Cheers!
I have been waiting for this.
Im so happy i found this channel, very informative! Can't wait for the galaxy ring test!
The person who has the most credibility and accurate scientific analysis of smart watches💪👍
Thank you so much!
You're welcome! ☺️
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.
Great job man! Thanks for such a great content!
Awesome, this is the definitive review I was waiting for. So much info as always and glad to see that Samsung did better this time around
Hi dude. I love your videos. I am wondring if the settings was on max precision: L1-L5 dual band ON.
TNX SO MUCH❤
I am wondering the same question. Due to difference in battery size, and L1+L5 mode probably more battery consuming than L1 only, maybe the Watch 7 40/44 mm defaut setting is different from Watch 7 Ultra defaut setting, regarding GPS tracking precision.
www.youtube.com/@TheQuantifiedScientist Could you please give the setup of both your Galaxy Watch 7 40 mm and your Galaxy Watch 7 Ultra, during the GPS tests, regarding the GPS accuracy tracking ?
Thank you for all the work you put into these videos!
Wow, so disappointing. I own a PW1 which has performed brilliantly but I wanted a 2nd device. The previous time I tried a GW was the 5-series and that went back in under a week because the GPS accuracy was so incredibly bad. I thought for sure this would be the one but apparently not. Thanks for getting this out as quickly as you did, Rob.
Please review the Xiaomi Watch S3 and S4 🙏🏻
This chart makes me think the galaxy watch is doing too much averaging in software. That would help explain the delay compared to the H10 and the fact that it misses short HR dips. The good news is that can be resolved in software updates.
Then again, your correlation charts indicate why they're using so much software averaging.
The GPS data is certainly interesting considering the phones share the same hardware so you would think the only difference might be some layout changes. I wouldn't think you would see this much of it difference in GPS performance. This makes me think the 7 is making some GPS compromises in software to improve battery life. It would be pretty unfortunate to find out the 7 derates performance in software just to make the Ultra stand out as the better device.
Is the Samsung Watch Ultra full review coming soon??
Great review would love to see the results/comparison of previous galaxy watches.
Brilliant video, so informative and love the extensive data points :)
Glad you enjoyed it!
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!
Oh yes, been waiting for this! The new BioActive sensor didn't seem to improve the results... A disappointment. As for the Ultra being better for GPS, I'm wondering if its larger battery means programming has been tuned to poll more frequently? The body impedance measurement... if true [it's not], 2.9%, you'd have very low testosterone levels, and over time become depressive, probably. I usually take 5 or 10 measurements in a row and calculate an average because they vary somewhat. They seem to be very sensitive to how the fingers are placed on the two button sensors, also tightening the strap, and placing the watch a bit higher up on the arm. When you do gym testing, please consider testing the rep counting, too. I wish Samsung released access to this for external apps. It used to be part of all Wear OS watches in Google Fit, until Samsung entered the scene. Unless there's review data out there, I believe Samsung will rest on their laurels for this particular feature in terms of where they allocate their development resources. Looking forward to the follow up.
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.
Wait a second, how come the watch ultra is better than the watch 7 at detecting sleep? They use the same sensors...
Thank's! So, same story as Galaxy 6 for sleep. Not worth it the upgrade.
You are definitely my reference device!
Thank you Rob! Just what I was waiting for.... Now it is decision time -stay or go.... Keep up the much appreciated work!!
Make a video comparing Galaxy watch 4,5,6 and 7, it'll a make a great purchasing decision for activity tracking
this guy's gem. thanks for the killer content
You had me at the start there. It looked like Samsung had turned a corner and finally made an accurate watch but as the video progressed it became evident that it’s just as bad or worse than previous Samsung watches 😅
Awesome review, as always. I'm impressed about the blood pressure sensors. Only that 😅
Great review rob! Thanks!
Thanks!!
