Intro: However, how about the other health and sports tracking features? Are these any good on the Mi Band 6? That’s what we’ll test in this video. Specifically, we’ll test the sleep tracking, oxygen saturation measurements and step counting. And, we’ll also summarize the heart rate testing from last week to provide a complete scientific overview of the Mi Band 6. And, to summarize, overall I am quite encouraged by the improvements of the Mi Band 6, though not all features are that accurate. With rumors of the Mi Band 7 being on the horizon, some of you might be waiting for this to be released. However, the performance changes of the Mi Band 6 actually show us that firmware updates months after releases are sometimes needed to get proper performance out of a watch, which might make the Mi Band 6 a more attractive purchase for some.

To start with, the thing the Band 6 was worst at out of all health related features is sleep tracking. I tested that in several ways, the first is by checking if two Mi Band 6’s worn at the same time detect the same sleep stages. If the sleep tracking algorithm works well, it should give roughly the same results for two Mi Band 6’s. If the two watches are not consistent, that means that either the raw measurements themselves or the algorithm underneath is not very stable. For 3 nights, I wore one Mi Band 6 on my left arm and one on my right arm, both running the same firmware. Now, the fact that I wore one watch on the left and one on the right hand could introduce some differences in the movement data both watches record during sleep. However, this is something that a good sleep tracking algorithm should be able to deal with. If not, this means it is inherently unreliable at estimating your sleep stages. Let’s see if this is the case!

Conclusions: Where I was quite negative about the Mi Band 6 when I tested it last year, it has won back a small place in my heart. It isn’t one of the best health or fitness trackers out there, but, for the price it is not bad at all. For 35 dollars you get a smartband that is pretty decent at most health tracking related functionalities, except of course for tracking your sleep stages. The SpO2 tracking seems pretty good, and so does the step counting. The heart rate tracking is OK, though not the best. Now, with the Mi Band 7 rumored to be released soon, it might be worth waiting for this. On the other hand, the Mi Band 6 is likely cheaper, and has more mature and developed firmware. It’s up to you to decide what to do, and of course I’ll be reviewing the Mi Band 7 as soon as I can get my hands on it. If you care about good heart rate tracking, check out the videos I made on the Huawei Watch GT 3 and Huawei Watch GT Runner that have amazing heart rate tracking right here. If you are looking for a smartwatch from a more premium brand, check out my review of the recently released Garmin Watches right here. Now, I hope this video informed you on the health and sports tracking capabilities of the Mi Band 6. Thank you for watching, and catch you in the next video!
