We shouldn’t have to wait for updates / new firmware as much as we paid for these watches they should have been right on release period. My ultra may not have the best battery but it does everything I want and it’s pretty spot on at everything !! And for the battery it’s simple I throw it on the charger every morning when I hop in the shower so a dead battery is NEVER an issue!!! And it worked out the box !!!

Hi Rob, Great Review as always. I was wondering if you could add one reference value for the heart rate accuracy (maybe the R-value and its std. Deviation?). This way you could compare all devices in one chart just as you do with the sleep accuracy. But these are already the most informative fittness based reviews anyone could ever find. Keep up the good work 😄

I noticed the F7 measruring O2 to low with the widget, while in healtsnapshot it starts low for a few seconds and then settles for a realistic value.

Hello, We really appreciate the effort and time you're putting in these tests. Would you please make the test again with the latest software update 11.28. Garmin is claiming that it has fixed all the issues reported in your tests but we still have all those issues unfortunately. All the community relies on you to prove the contrary. Thank you so much again.

Great analytic video! Well done. Question, in terms of robustness of build, to suit activities such as hiking in rough terrain, team sports like soccer or touch rugby, would the epix 2 be a worthwhile option?

And this is why I’ll stick w/ my Ultra during hiking & deal w/ charging it while at rest sections. I value the health data accuracy & I’m not one to wear a chest heart rate monitor honestly. Great review.

Hi, thanks for this video! Do you set the activity in the garmin, like "running" or "biking", before recording? In my experience it makes the difference

So pleased that I found this video. I have had an Epix 2 for about a month. Previously I had a much cheaper Amazfit armband. I was getting concerned about the sleep readings I was getting from my Epix - mostly "non-restorative"! Compared to the Amazfit, the Garmin showed far less deep sleep, far more awake and less REM. I personally often felt well rested from my sleep during this period. From what you found, and my experience, the Garmin algorithm seems to be lacking. For me, I feel that it may be the effect of movement during sleep - my wife says I am a restless sleeper.

Great video as always. I appreciate the depth of the comparisons, you give great context with other watches, both from Garmin and other brands.

Thanks for the video, Could it be that the watch is just too big thus it is having hard time recording heart rate/Spo2?

I have a Venu 2 which has the same Elevate 4.0 sensor as the Fenix 7 and Epix 2's. Recently there was an 8.05 beta firmware and since then, it seems like sleep tracking has gotten a bit worse. I've had a couple of cases where the watch incorrectly reports a sleep period while sitting and working at my desk. This was not the case in previous software versions. I definitely agree that Garmin need to up their game in terms of sleep tracking algs. Tracking maps would also be a welcome addition. Obviously this is "beta" software, however garmin say on their forum post that this is likely a final beta before release. Hopefully Garmin do continue to expand features on these new Elevate 4.0 devices. Great video as always. Thanks Rob!

Hi Frederic! Indeed, but it is always good to check. Also, it is interesting to see how consistent sleep tracking is when wearing a similar (or the same) watch. Fitbit has always been much better at this with mostly >80% agreement over all stages when wearing two watches (even when they are different models). Not sure indeed how much weight plays a factor for sleep, but an interesting concept 😊👍

I am wondering how the sleep tracking from the Apple watch compares? It doesn’t look like any wrist wearable performs exemplary in this regard…

Nice review! Two quick questions: 1)Why you think apple 7,Huawei gt3 and Venue 2 plus have the most accurate heart rate results during weight lifting? Does it have to do with the sensors? The shape? The size? What are your thoughts? 2)Any tips for better heart rate accuracy? For example what kind of straps do you find more effective for steadiness on the wrist during weight lifting? I would really appreciate your suggestions!

Hi! (1) I read that Apple really invested a lot in making sure that even when worn quite loose, the watch could still measure heart rate. I suspect it is a combination of great enginering and algorithms (made possible by a lot of talent and budget). (2) I prefer the fabric straps with velcro that you can adjust to any size. For me these gives the best fit. Have a great day!!

@The Quantified Scientist Which 3 Advance Health Watch are the Best for Tracking Sleep; I believe the: 1st is Apple Watch 7. 2nd is Fitbit Sense. 3rd ? I don't know.

I think during the indoor exercise the low signal of GPS affects the performance of the watch in heart rating as the watch keeps searching for the location and it has a logarithm of calculating speed distance along with heart rate. Just guessing

This was great! Especially the comparison of the similar models. Keep the data coming.

However, this is all based on older data from months ago.

Thanks for the very informative video. Love your approach as it's pretty hard to fool science. I've got an Epix 2 on order and should have it within the month. Do you think that accuracy can be improved by software updates or can it also be a hardware problem?

One thought about SpO2 measurements on watches: since this is so stable at ground level in healthy people, these comparisons do not tell much, do they? They could just show 98% all the time and would be more accurate than whatever the watches measure. Therefore, I think the only really useful comparison is when SpO2 is actually lower than normal (like on a plane in one of your previous videos). Another thing: have you considered Bland-Altman plots instead of the boxplots for comparison?

Great video again! I have the feeling that your scatter plots for the HR accuracy are sometimes a bit misleading: there are almost always enough values on the diagonal line so that it appears black. However, when you have a lot of measurements, you also have many data points away from it. Therefore, devices for which you have a lot of data points might seem less accurate. For instance, the results of the Epix during spinning don't look good on the scatter plot but look OK when you show the individual rides.

@@TheQuantifiedScientist Hi Rob! I have even better ones. Here is your video of the published study from Garmin (2019) on their new accurate sleep algorithm: kzread.info/dash/bejne/gI2pqJOjm9mqgLQ.html. And here kzread.info/dash/bejne/gI2pqJOjm9mqgLQ.html you wonder why your test results differ from that Garmin study. So here's the answer: you've been testing on the wrong devices. There are two types of Garmin watches: 1. The first type uses its own processor, display and firmware with its own built-in algorithm. They can work completely autonomously. 2. The second type does not have its own display for viewing sleep data, training, heart rate history and so on. To do this, he needs Garmin Connect. But, even synchronization between them and Garmin Connect does NOT work without the Internet - you can easily check it yourself. They need a cloud. Just check the Garmin forum link: forums.garmin.com/apps-software/mobile-apps-web/f/garmin-connect-web/108946/using-connect-app-without-internet-access/984760 Why Garmin insert the worst algorithm into devices? The answer is here in your other video kzread.info/dash/bejne/f66FtsOYlsrWZZM.html. You answered it yourself: Vivomove Sport has less sensitive to movements. And this is a drawback - it is weakly sensitive to movements and poorly sees the beginning and end of sleep. And this is a serious marketing problem for Garmin, because the user can easily check for errors in determining wakefulness, the beginning and end of sleep, but sleep phases or their duration cannot be checked (at least until the appearance of the video channel from Dr. Rob of-course). Therefore, Garmin sacrificed the accuracy of the phase detection in the new algorithms in favor of better detection of wakefulness. But algorithm of 2019 never disappeared, it was always there, in the cloud. And you found it at Vivomove Sport. And you can find it in other Garmin "cloud" watches too. I am pretty sure of this. I use two bracelets at the same time on one arm: Inspire 2 and Vivosmart 4. When I look at your sleep data from Vivomove Sport kzread.info/dash/bejne/f66FtsOYlsrWZZM.html, I recognize the Vivosmart 4 algorithm in them (the same smooth and wide REM phases, very thin or no awakening bars). Also, Vivosmart 4 does not always correctly determine the beginning and end of sleep (especially if you read a book before going to bed or are inactive). And this, I'm sure, is exactly the reason why Garmin abandoned the 2019 algorithm in their expensive devices. I doubt that Garmin would openly write about this. If only because no one asked about it and it would hurt his marketing policy and sales of expensive devices. I know that there is still no direct evidence, but you asked kzread.info/dash/bejne/i36Gt7lpkd2voc4.html about versions. So this is what they are 😊 Thank you for your video channel and wish him good luck!

If Garmins performance depend on its algorhithm which I guess sample rarely to keep the outstanding battery life. I would happy if Garmin come up with an update which gives an option to switch to an alternative algorhithm which measures more often and gives better/closer results to "reality" at the expense of battery. I could live with 1-3 day battery life but I wouldn't buy something what is not accurate in something that is important for me. Now Epix is lost its value for me, right after i ordered it but before I paid it... Thank You for the video, very much!

Can you please write names of tge devices you mentioned? I didnt understand your speech

I had the same experience with the epix 2 when riding my bike last week, it was just not responding to my effort, I didn't believe my heart rate was so low. I've started to wear my apple watch series 7 althought it's the stainless steel which is a bit heavier then what's usually tested. Problem is I want to broadcast my heart rate but apple doesn't do that without an app and the iphone :( . I use a hammerhead karoo 2 bike computer which I'm loving, and they do updates every 2 weeks.

What about taking into account the weight and diameter of the wearable, the larger or heavier means the sensors are moving on the arm more, causing poor readings. Just a back if the napkin thought.

I hope You will test them again after all the updates.

Will you be uploading an ECG review for the Withings Scanwatch & Fitbit Sense? Considering ECG is the specific reason for their price hikes I hope you can help with that soon. After watching your videos this past week it seems none of these watches are worth it when your research shows such low accuracy and wide variations when it comes to the special features such as sleep tracking & spO2.

Thank you for the review of these expensive watches. When I am not focused on sport specific activities I use a Galaxy watch 4 for everyday use. Since the last big update a few days past I have tested it and I have seen improvement on GPS and sleep tracking accuracy. For 4 consecutive nights since I have tested it I got very beautiful graphs of light, deep and rem stages. I constantly got at least 1 h of deep sleep (which is a very big difference from my usual 15 min ler night) and the rem stages are very clear. I can see pretty good 4 to 5 cycles. I think they did something to the algorithm besides the "animal" bases profile and sleeping coach feature. If you have the time to test the watch for a couple of nights and inform us if something really changed and it is not just me being very lucky, it would be appreciated. 😊

My son has it. He reported the same, not perfect but much closer to reality now. Also the new features they added are pretty cool. The sleep coach is making relevant suggestions.

@@krollpeter yes, it is useful. Last night again I had very good measurement with 1 h and 20 min of deep sleep, 2 h and 20 min of REM and very few awake moments. I could see 4 sleep cycles. They did something to the algorithm for sure.

@@sergiutelbisz1955 It has to many awake sections for my son. They even count moments he's turning as awake. My Huawei has too less, as we found out in direct comparison. Even if I wake up and go to the bathroom it does not show it. The Samsung is sure more than a toy after the update, unlike so many others.

@@krollpeter for sure. If you go to the bathroom and Huawei does not show it, it is not accurate because you are awake. My awake time since the update with GW4 went from aprox 50 mins per night to 25 now. I know that it shows sometimes a simple turn of your arm while you sleep as micro awake time but now, for me, it shows fewer moments like that.

But what is important is that the way I feel în the morning correlates with what is being shown. It's a start. Hope they will improve it more.

It's time to fix the name of the Vivomove sport in the percentage agreement (it's called Vivimove in your graph). Thanks for the valuable content!

Do people know when the Venue 3 will be released?

Can you please test the Polar Grit X Pro ? As I remember from your video of the Polar Vantage M, that model had great sleep and HR monitoring Thank you for your great videos!

This channel got recommended to me. I have sleep apnea and im looking for a sleep tracking watch with a 24/7 SPo2 reading. My candidate so far are the Withings Scanwatch, The Garmin Venu 2 Plus, The Garmin Epix 2. The only reason I did not have an Oura ring is because of the subscription and the limited service in Canada. I'm also looking forward the new Google watch coming this year. If you have any idea and opinion on what is the best watch for this purpose it would be really appreciated !

Hi! I did not test the sleep apnea functions, so it is difficult for me to judge. I think these devices do not just use SpO2, but also try to track your breathing, though I am not 100% sure of that. I think the Withings Sleep Analyzer should be able to do it based on breathing, though I am not sure if they are certified in Canada. However, I cannot really say more than what I read online, since I did not test for sleep apnea.

@@TheQuantifiedScientist That i understand, wich watch would you recommend for the best sleep tracking + sp02 ?

February 2023 I decided on Epix 2 due to the lovely screen and now pairing it to Garmin HRM Pro Plus Heart Rate Monitor and live the fact I can take watch off and it records to heart rate sensor then pushes it to watch and app soon as I stop the workout 🥳🥳🥳

So, is the Garmin Epix Gen 2 all sorted out these days? (July 2024)

Why aren't the two matrices at minute 5:13 just the transpose of one another?

hey will u be testing the mi band pro?

just commeting for the algorithm, gave a like before watching as always

Did you test the Fenix 6 Pro?

Garmin has just released a new update for most of there watches that you have recently reviewed. Sleep algorithm has been updated also I wonder how this update will either improve or not improve if you test them again.

Did you rest the sleep tracking with new software?

Sounds like a lot of money for something that can't really compete against products 1/3 the price in some critical areas like heart rate. Really glad I found your channel and eventually went for the Huawei GT3 Pro for £240 - finding it really great to use.

Can you please review Fenix 6? It’s less expensive than the 7!

Hi Rob, thanks for the great video! Question for you: do you think it was this generation of sensors by Garmin is better or worse than the previous generation of sensors in sleep tracking in general? Also, by any chance, will you consider reviewing Garmin instinct 2/solar? Thanks!

@@TheHUhelps well couple of points . He reviews watches when they launch and never checks back. Every watch comes with updates that fixes issues. Huawei watches have been the worst for me heart tracking and sleep but he shows a different story . Also as per analysis venu 2 plus and oura ring are inaccurate watch for sleep tracking , but for my analysis these are top most accurate watches . Anyways hear him with a grain of salt .
