This video serves as a warning, both to you and to me. I expected when I bought two Huawei Band 9’s that their heart rate performance would be as good, or maybe even better than the Huawei Band 8. The Band 9 looks more or less the same as the Band 8, and the Band 8 was one of the top performers in my testing last year. With a lot more time having passed to develop the hardware and firmware, I was hoping Huawei would be able to squeeze even better heart rate performance out of the Band 9, and I assumed it would be at minimum as good as the Band 8. But the saying appears to be true, when you assume, you make an dot-dot-dot out of you and me. Today we will take a look at my initial testing of the heart rate tracking performance of the brand new Huawei Band 9, and you can judge yourself if you are disappointed too.
Now, this is only an initial test, but it was so surprising that I wanted to get this video out quickly. The question remains, why would the Band 9 do worse than the Band 8? Well, one explanation could lie in the sensor set. It seems Huawei changed the configuration of the LEDs and sensors on the back of the watch. Now, this is not my area of expertise, but looking at it you can see the Band 8 has two sets of LEDs on the outside, with the large photodetector in the middle. The Band 9 on the other hand has aone set of LEDs and photodetector very close to each other on top, then another set of LEDs exactly in the middle of the watch with a second photodetector a bit further down. Now, I don’t know how the signals from the photodetectors are combined, but it might be that the software is not optimized enough yet to deal with these two independent signals. However, this does not seem to be the first watch where Huawei uses multiple photodetectors, looking at the back of some of the GT series watches you can also see a symmetrical ring of photodetectors around a central pair of LEDs, so multiple photodetectors does not appear to be a new concept for Huawei. Now, this is all pure speculation, since I am not even sure if both LEDs and photodetectors on the Band 9 are used to measure heart rate, it might well be that one pair was designed for heart rate and the other for oxygen saturation. Still, these initial findings are disappointing, but we will have to wait for my full review to draw any final conclusions.

[@talkingmonkey7]

Your reviews are the best, i discovered the channel yesterday, thank you for your work!

[@spectrixx]

Rob, I had initially been waiting for your thorough review of the Band 9. But, like you I assumed that it would be at least as good as the Band 8. So yesterday, knowing that your detailed review would take at least a couple of weeks to come out, I placed my order. Thank you for rushing a preliminary review out. You have saved countless others from making the same mistake that I did! I can only hope that Huawei make some firmware changes and improve the heart rate tracking. It'll be interesting to see if Huawei's claim of improvements to sleep tracking performance checks out. Keep up the good work, your reviews are nothing short of spectacular.

[@jieweizhang4967]

Hi , will you be able to do a review for HUAWEI WATCH FIT 3? Thank you!!!

[@snipershotsphotography7915]

I've been waiting for this review, thank you!

[@jesherkiwwa4748]

Huawei needs to explain it's self as I bought this one because of its improvement as stated but eventually not, I did compare it with the Huawei Band 8 and also wore both devices and compare them to a pulse oximeter and Huawei Band 9 had struggles on detecting my heart rate compared to the Huawei Band 8... but I hope updates will fix this issue..

[@huwix21amx33]

apple is soo bad older huawei beat the newer apple/ i have seen more real test and huawei destroy apple ez and apple watch broke in water my teacher had one hahaha apple/ and i never had a issue with my huawei watch.

What firmware are you on?

[@jesherkiwwa4748]

@ If you're referring to the Huawei Band 9 it's HarmonyOS 3.1.0.31 and for the Huawei Band 8 it's HarmonyOS 3.1.0.31

[@noexit6764]

@@jesherkiwwa4748 updates will not much help if the problem is hardware related, i hope it is software related lol

[@heyamax]

Huawei dont need to explain anything. So you really think what he says is true because he claim to be a scientist?

Thank you for the video and your effort. I would love it if you had some of your own tier list

[@aaronkwok7201]

Thanks for the thorough reviews 👍

[@whoisalisson]

Thank you for listening and bringing us the Huawei Band 9 review! I look forward to the full review as I'm looking for a cheap smartband for sleep monitoring mainly.

[@whoisalisson]

I hope Huawei can improve the Band 9's fitness tracking performance over time.

[@Deeren97]

I'm in the same boat, looking for a rather cheap band mostly for sleep tracking, I went with a used Fitbit Inspire 3, one of the best sleep tracking right behind apple watches, though I haven't gotten my hands on it yet.

[@MrIndependency]

I bought a huawei band 8 for myself a couple months ago and a huawei fit 2 as a gift after watching your reviews. I'm quite satisfied with their performance. Thank you for your work, sir!

[@vrea7260]

liked before wacthing it, been waiting for this, thank you Mr. Rob

[@yasskb]

Rob, imagine it's a firmware issue, and that Huawei also make the Band 8 worse with last updates like someone else said ?! It could be interesting to test the Band 8 again...

[@ralfrufus6573]

And tell us the firmware version!

[@carlosmiguel4756]

I saw your video about the Huawei band 8 and was ready to order the band 9 this week because the price is stunning €49 with promo code. Thank god that i waited...but really what's happening, i thought that at least performance/accuracy should be equivalent. I bet this is software related but either way, gonna wait a couple of months now to see the improvements and hope you further test it. Good work!

[@fluffypuffyboy586]

they are abusing dumb customers. who always buy the never model regardless if it is better or not becouse they dont realy care about the accuracy. Just look at the Reviews from so called "tech" youtubers who never not even closely talk about the technical sides of the devises and just talk about the outside stuff and software features.

[@whoisalisson]

​@@fluffypuffyboy586 That's true. This is the only KZbin channel I know of that deals technically with these devices. Which is absurd, after all, all these smart bands have the primary function of being a good health monitor, not a computer or smartphone.

[@lemonde1664]

Thanks for your job, best reviews on KZbin so far

[@rodrigoterabe]

Thanks for this! Really shows your consideration to yout subscribers!

[@IrisZhang-ts9zu]

Thanks for your quick reviews. Can you please do a review for Honor band 9 as well as Honor Haylou watch? Thanks alot!!!

[@sammyt3514]

I've come to expect methodical, science-based testing of different wearables from Rob; what I didn't expect was to howl with laughter which is exactly what I did when I heard the Huawei Band 'NEIN' quib 🤣🤣🤣. Thanks for the brilliant tests, and the laughs!

[@Gugle-vl2wr]

Thank you for your amazing work, as always. Your reviews are second to none and it's surprisingly satisfying to watch all the data resulted from your accumulated effort, every single time. It's unfortunate the band 9 ended up delivering underwhelming performance. I'd been waiting for it, hoping to get it over the band 8 since it reportedly has ambient light sensor. Oh well, band 8 it is.

[@BradMoss]

Love your videos. Thank you

[@nguyenhieu7633]

Thanks for your work, very appreciate

[@vscos56]

Really good huge effort for reviewing..thank you

Do you already have new Huawei watch Fit 3? 🤩

[@mauriciolguin]

Many reviews were released yesterday. But I'm expecting for this one.

KZbinrs have had Watch Fit 3 for weeks already. Some of the even comment on that in their videos.

[@mrheru8627]

[@user-mb8gk3en3o]

Brother, pls make test new Huawei Watch Fit 3. Very interesting, still it good or not.

[@weiavec4851]

Thanks and look forward to your full review about HUAWEI band 9.

[@rcblozada8877]

Let's see how the new Trusleep performs. 👍👌

[@TtotheMIM]

I'm just getting into your channel. I love the style! I've seen several of your videos. Do you have a website that has all the graphs you show? Heartrate for each of the exercises, sleep tracking, GPS, sleep, etc? It would be awesome to be able to see those all in one place

[@Lavender-fk9gm]

It would also be great if you will add The Pulse Wave Arythmia Analysis feature on your review. Also Huawei needs to see this video so they can addressed this issues. 😊

[@CrayonConoisseur]

Please do a review for Watch Fit 3. I bought the 2 from your review. Thank you so much for your quality content :)

[@aljoriz]

@TheQuantifiedScientist Is it possible to include in your reviews the battery performance of watches vs manufacturer claims? charge duration?

[@vaycheslavshem4859]

We have to wait for a software update....

[@sco0och]

bought this last week, and so far, I've mainly been using it for running. im happy with it though

[@user-bw1to3mh8d]

Could you make a video about blood pressure measurements? Methods, algorithms and so on. Lots of brands claim, that they have this function onboard, but in practice it is absent, or it works inproperly etc.

Great work! I will be waiting for the sleep tracking review but i am almost set my heart on the band 8

[@AlessandraSanan]

Thank you very much ! I was waiting for your review to buy this Smartband (or not). Now I am thinking about buying a Band 8 , I am just wondering if the one of Huawei or Xiaomi. As a matter of fact, I am interested on the SpO2 measurements.

[@zakariaelrhandouri3054]

thanks man ..because of you i bought huawei band 8

[@claudiubarbu4372]

When we'll be able to watch the full review, Rob?

[@adolfomartinez8620]

Hi Rob! I’ve been testing apps that imitate what whoop does but for the Apple Watch (Superset and Athlytic). A video comparing these to the whoop strap could be a great one (and a cheap one also )

[@ralfrufus6573]

I missed your mentioning of the improved strap. It now has a button to fixate the longer end.

[@Smartphoenix1982]

Is there no one to beat the Apple Watch accuracy??? Its a shame for the entire Industry.

[@gabriel95i]

Huawei gt

[@ana_carolina251]

pixel watch 2 is a great alternative

[@nae-sb1yh]

Apple has the best team of engineers. Apple is the richest company in the world. When you combine these 2 facts, it's easy to understand why Apple is so far ahead of everyone in the silicon game.

[@JakobDam]

I believe the sacrifice for the high accuracy is power consumption. Although Apple Watches have around the same battery capacity as fx. Garmin and Samsung, the battery life differs by an amount of x4-x20 depending on model and usage scenario. Such huge differences are obviously not something caused merely by optimizing algorithms for consumption, so something else is at play - and I believe Apple's choice of sensors draw more power, and they're activated more often, for a better and more consistent result. However, this also causes excessive battery drain. If Apple were to offer something like a "Precision" setting where the Apple Watch would poll its sensors less often at the expense of accuracy, I believe they would last 3-4 days instead of the current 1-2 days, bringing them closer to the competition.

[@mastercrossing]

​@@nae-sb1yh That is true. It is also true that Apple is kinda of a standard and a trendsetter with the headphone jack; the first Apple watch also removed the charger brick when it was a new iPhone.

[@doshase]

Can u please do the new huawei watch fit3

[@issa3476]

bought this thinking it would be better than band 8. i have high hopes with its new sensors, yikes. might as well wait for an update for Huawei to fix this with a firmware update, hopefully. thank u so much for your effort in making this video!

[@AIKTV]

Are you planning to make a video about the new Huawei watch fit? Because you had praised them in your studies. Since these now have more power, it would be very interesting to test them. I'm actually waiting for a typical science video from you so I'll buy it!

[@chelseasaldivar3397]

[@fred3435]

[@mahamoudtraore2339]

I am looking forward to it

[@ivanchuabh]

It's a shame. I bought it on launch with an early bird discount. I haven't tested its heart rate tracking during sports but for daily use, it does serve its' purpose. Hopefully Huawei sees your video and updates its firmware to become more accurate... goodness gracious me. Edit: Having it for about 10 days now as of this reply. This is my first health tracker band and first Huawei band. Battery life is very good, and I hardly ever feel it on my wrist. I'm actually more motivated and strive to exercise more. I don't miss my Garmin Fenix 6s pro at all! I have to say, despite its' inaccuracy in heart rate monitoring, the band functions as it should, which is to motivate me to exercise. I consider it a win, although I do hope that firmware can still be sorted out to get the best value for money regardless.

[@paulcannizzaro399]

yes, your diligent testing has earned a subscribe and a like :D

[@MrTariqmaster]

Thank you for saving me from buying this band, i was about to buy it when i read it has the same Trueseen 5.5 optical heart rate sensor as the GT4. Keep up the great work.

[@andoriz0r]

Dude I literally just bought it because I ASSUMED it will be at least as good as the 8. Well, lesson learned. Hopefully they can improve it by updating the software.

[@AM-qo3nx]

Same here, and the sleep track is awful too. What a junk watch only the watch faces are nice but useless

[@milanaabaevatv3311]

Rob, do you think huawei will fix these problems with tracking activities? If so, I am wondering how soon?

[@dylans2669]

Thanks, i ordered the Huawei band 8 instead of the 9. Maybe they will improve the 9 down the road and then i can upgrade to that and hand the 8 down to someone else, but for now i need something that is fairly accurate. I wonder how accurate the watch based ECGs are... i suspect they are not.

I think there should be a comparison with band 8 with the latest firmware..

[@yasskb]

Absolutely

[@uralmutlu4320]

Despite the negative review, I'm gonna get this watch/band. R=0.99 for running is pretty good. I expect its got better overall sleep tracking than the previous generation as well. This band is not out in my country yet, so if the full review comes out before then and the sleep tracking is also poor, I might just as well go for band 8 or xiaomi band.

Hopefully they'll update and improve the firmware by the end of June - when my Band9 gets delivered. And I might wait for a sale to get the Galaxy Watch6, specially with the 7 about to be release, so the price will get lower.
