This kind of videos will always keep the Smart Watch companies on the run. They will think 50 times before giving false information to customers. Thanks a lot man! I really appreciate the video.

[@TheChocoSama]

This is just what I was looking for! To me, this is a highly detailed search and you have presented its results in a perceptible, convincing way. I just loved how collected and organised you are (also polite). Keep up the good work sir!

Awesome, thank you!

Indeed

[@koya__kim]

I was thinking of buying my first fitness band, and I thought Mi Band 5 would be a good entry level device. I scoured KZbin for reviews, mostly just unboxings.. and I stumbled upon your channel. Very amazing well thought-out analysis video. You have a new subscriber, sir. Keep up on these quality or dare I say quantified videos. Have a nice day

Probably my first comment on youtube. Thank you so much! Exactly how accurate the bands are has always been an interest of mine. I've been looking for similar videos or online comparisons forever and no one is doing it. Keep the work!

Thanks for commenting Denislav!

Honestly, with all this so called fitness devices on the market, this channel is a blessing. Keep up the scientific comparisons and please do mi band 6 as soon as it is available. 💪🏾

Thanks!

[@chakree100]

I’m a researcher myself in wellness tech, thought of making a similar style paper and u absolutely nailed it! Keep it up u r doing a really good job! Huge companies like Apple, Fitbit and samsung have become so overpriced in the name of accuracy, precision and reliability. Good job I’ll suggest this channel to people who are interested to buy new fitness trackers

This is an another level to the reviews. Best I ever watched. Make a Patreon community. Sure people 'll love to support you. Keep up the good work.

Just bought a Mi Band 5. Noticed that arm swings, even when not walking is added to walk total.

[@gunner4ever924]

Thank gosh I watched this video before buying it.

[@DSTWizz]

Thanks so much for this! I bought a Mi-band 5 only a week ago (to replace a Mi-band 2 which fell off), and so far my experience matches yours. Altogether it seems to be much more accurate than the old model, but I haven't checked it while cycling yet because of the bad weather here in the UK. My step counter seems very accurate, but I haven't checked the heart monitor when doing vigorous exercise yet. Some other features of the and are very useful too (like reading notifications on the wrist, etc.)

[@richards2072]

Superb video analysis! Simply the best I've seen. Looking forward to watching more of your tests. Thanks very very much.

[@TheQuantifiedScientist]

Thank you very much Richard!

[@iamvinku]

This is a beyond amazing scientific review of the Mi Band 5. I'm glad to find out that the Mi Band 5 is not that bad when it comes to accuracy when you look at the price of the thing. Thank you for such a detailed, scientific analysis.

[@francobellomo9979]

Hi, I really liked your video as I am looking for a good cheap sleep tracker. A tip that I read in several places is that the heart rate can be affected by light, so there are many people who put a scarf next to the wrist to block the entrance of light to the watch.

[@rajveerchomal234]

He is smiling throughout and that’s what makes the video better !

[@paragadlakha]

The best accuracy test on the internet. Amazing video man. Would love to see the similar test with honor band 6.

[@lollycopter]

I've had this watch for over 3 months now and this review gave me pretty accurate expectations. Regarding measuring higher heart rate (at least when cycling outdoors), I find that it's more reliable if I have the watch *quite loose*, and low on my wrist. Gravity should be enough to keep the watch in contact my skin, and that is all that's needed. My hypothesis is that starting with the watch tight means that as the wrist warms up from increased blood flow, it swells and becomes too tight for a pulse to be detected by the watch. My skin is of a neither light nor dark complexion. So long as there's contact with skin, it should be close enough to see the blood flow. The most difficult readings come when my skin is cold - there's no real way to get any kind of an accurate reading if that happens. Also, I keep this watch charged between around 75-65% as much as possible (an analogue timer for my power outlet helps) to prolong the lifespan of the battery so I shouldn't need to throw this away too soon. I think this watch is pretty good value for the price, given that a lot more money would probably need to be spent on anything significantly better.

Excellent review! I appreciate your empirical evaluation. My doctorate is in machine learning, and I've always had difficulty sleeping, so automated sleep scoring is very interesting to me.

You channel and the testing you do is amazing!! I'm planning to get a fitness tracker band/watch soon, your way of doing detailed analysis with comparison to devices what's used in labs/more advanced tech is so helpful!!😄 Excited to see an update on the heart rate part when you do!

[@Rugiada1035]

Loved it! Scientist here too, so seeing something so well made feels great! I was wondering how results change when using the MiBand with a different tracking app, like "Sleep as Android" for night sleep and "Notify for mi band" for sleep, steps, and workouts. I prefer the latter over Mi Fit as it allows to change so many settings, even the heart rate sampling. I suppose each app applies a different raw data elaboration, which makes it really interesting for me :)

Very useful and informative video. No words to thank you sir. Great comparison with more real authenticated data

[@TheQuantifiedScientist]

[@rachitajitsaria1254]

Great vid. As you mentioned, false positive in steps tracking is also important to test and also maybe how well they perform after say a few months to understand if the sensors are still accurate. Also, as you mentioned data on other people would be helpful. Many people believe that the heart rate tracker tech performs badly on people with darker skin so would be interesting to see the variability there.

[@iamqueen1211]

Thank you so much for making this video :) ! This really help me setting a correct attitude to the data I got from mi band

[@romanliebl1914]

Great Review! Thank you being the only Reviewer, that makes thoose sience backuped comparisons. Could you please do a comparison with the Garmin Fenix 6? As it is known to be one of the best Sportstracker / Fitnesstracker at a high price point and all the reviews I have seen so far are kind of subjective when it comes to sleep / heart rate / steps and other metrics.

Well done 👍🏼 It’s clear that you put a lot of work into this video. Thank you

[@TDG361]

Thanks a lot, this is what I wanted to see. I have seen that the Mi Band 5 is a bit bad in step counting. It counts steps when I'm sleeping or even when not wearing it. It seems to work well when running, I have no reference, but it detects the changes in heart rate as it should, that is, when I increase the pace, it detects the increase in heart rate, and when decrease pace, also detects the decrease in heart rate.

[@vaibhavchauhan7179]

Waiting for the detailed step counting video.... BTW thanks.

[@bviebhoey]

I'm working on the ship. At first I noticed that somedays sleep monitoring is working somedays not working. Then I figured out that if your sleeping in a moving place like a ship,the sleep monitoring doesn't work. When the ship stops then sleep monitoring is working fine. Just for sharing..thanks for your video.
