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.
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.
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)"
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.
@@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
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 😅
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
@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.
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.
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.
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!
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.
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%
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!
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
Finally, I am grateful that someone addressed the accuracy of the galaxywatch ultra. Thank you very much for your review. Even though I love Samsung design, Apple watch is the king of accuracy.
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.
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
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.
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
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… 😮
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...
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.
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.
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'm 70 years old and heavily invested in the Samsung ecosystem (Galaxy Watch Ultra, S23 Ultra and Buds 3 Pro). I'm more concerned these days with monitoring my vitals than training for my next biathlon. This is a great video to let me know the accuracy of the Watch Ultra. Well done!
@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
Awesome video! Would love to see one about the sleep tracking of different wearable rings if possible 🙏 (Oura, Ultrahuman, Ringconn, Galaxy Ring, ETC.)
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.
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.
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?
Welp, I guess I'm not regretting buying a used Watch 7 for 130EUR and a used iPhone XR for 105EUR half a year ago (and turned out I'm getting the new OS, too). Using it solely as a health tracker, don't care about the iPhone nor the smart watch features. Keeping the watch completely offline (other than when I want to check my data on the phone - then Bluetooth on for synching), raise for display on also turned off - still have to charge daily (battery health at 85%), but got used to. iPhone itself is extremely restrictive, can't block apps from WiFi use even with jailbreak, no firewalls available. Battery health is 82%, I keep it on airplane mode and battery saving, yet it discharges a couple days quicker than a 2014 Sony Xperia E3 (that's been running daily since 2014 with no battery changes) with 2G on and receiving a couple SMS daily. Battery life on iPhone is ridiculous - and I can't even delete system apps like on rooted Android to fix the background battery hogs. And I thought IPhone's more efficient programming language will beat Android's Java in efficiency - no such luck. Good thing I never planned to actually use it for anything other than health apps.
for me personally, 700 euros is a waste of money, from what it looks like, it's not at all average, you can't call it a galaxy Ulta that even comes close to the Ulta apple watch, I've compared it to my friend's
Hello, thank you for the video. That is certainly an accurate (and true) tech review. I am curious if it would be possible for you to compare the results of the GW7/GW7U against the previous generations (Watch4 series and 5 series) in the full review - with the results from the previous reviews, of course! Thank you in advance!
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.
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 🙏🏽
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 😢
I like your scientific reviews very much and find them useful.👏👏👏👏 I even waited for your review to buy samsung galaxy 7, I'm glad I didn't buy it. I have a request from you. Could you also examine the heartbeat values of the watches in the pool or in the sea?
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
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!
My Samsung Ultra watch just arrived tonight. I love your videos! Do you ever incorporate oxygen saturation statistics? Do you export the Samsung watch data to access the watch's readings?
