25:31 Health Tracking Conclusions
26:14 Final Thoughts
Intro: First off, the battery life of the band 7 is pretty good, lasting 2 weeks with normal usage and up to 10 days with heavy usage. Additionally, the fast-charging should charge the band 7 with enough power for two days in just five-minutes. It is also water resistant up to 50 meters, however, it is not rated to be used for things like scuba diving or water skiing. The band 7 is not too expensive, costing 69 euros here in Europe according to the original information I got, but from what I found online that seems to be 59 euros. It is produced in 4 colors, including wilderness green and nebula pink, and the two samples I have here are flame red and graphite black. The Band 7 is pretty light, officially weighing in at 16 grams without the strap, compared to the 18 grams of the Band 6. The band 7 is also thinner than the band 6 by 1mm, now being about 1 cm thick. In terms of sensors, the band 7 has an accelerometer, gyroscope and optical heart rate sensors. With these sensors, it can automatically measure your oxygen saturation levels, and it also has continuous heart rate monitoring. Using the Trusleep 2.0 algorithm the Huawei Band 7 tracks the sleep stages you go through each night, but you do have to turn on that functionality. The AMOLED display of the Huawei Band 7 is much the same as that of the Band 6 at 1.47 inches and a resolution of 194 by 368 pixels. Now, before I show the results of my testing, I want to be clear, HUAWEI sent me these watches to test, but this video is not sponsored in any way, and they did not have any influence on the contents.
Conclusion: In terms of health and sports tracking there are a lot of things to like about the Huawei Band 7. Based on my testing, I find that the heart rate tracking is pretty good for the price, and the oxygen saturation sensor also appears promising. The step counting is also pretty much spot on, based on the tests I did. However, the sleep stage tracking is not something I would rely on, so if that is your focus, you might want to consider a Fitbit device, the Whoop strap or the Withings sleep analyzer.

[@bradmonk69]

As someone with multiple degrees in exercise science, I am loving the analysis of these trackers. This is significantly more insightful than other reviews which really only tell you the features, and nothing about the efficacy of the device they are trying to make you buy. You really should have more subs.

[@ltroy_sw]

Exercise science?! Damn, I never knew, that that was an option... Always thought, that rehabilitation, surgery or endocrinology is the top choice for a broad and medical education in exercising. How is studying it? What do you study? Can you explain Stimulating Reps theory, for example? How knowledgeable do people really end up after graduating? Please tell me, I am so interested in your experience.

Just found your channel. I'm planning on replacing my Mi Band 5 and I've binged several of your reviews. My Mi Band has disappointed me a lot, especially since they changed the app (from Mi Fit to Zepp Life). I've found your channel to be highly informative. I hope Huawei addresses the sleep tracking issues since I'm in love with its HR and step counter features. Never thought Amazfits were that bad, considering how good they look. Thanks for the info 👍🏾

I'm not a fan of wearable tech, but I needed a watch that's under 60 euros for tracking my activity, and seeing this perform better than the whoop which is very heavily sponsored and much more expensive , I'm happy with knowing it's not going to be a bad performer. the detail in the video is incredible so thanks for putting it out there !

Superb video again. Your hard work shows in the detailed analysis. One thing I noticed, the Huawei Band 6 though quite accurate as a step counter seems to have a mind of its own and counts steps even while the person is totally at rest and not even wearing the Band.

[@alessandrolanfranchi5913]

Hi, your reviews are amazing and very specific. Thank you for the work you do! I would all like to advise you to add the accuracy of gait tracking when you do sportwatch reviews: it would be interesting to understand, in addition to beats and GPS accuracy, which device is more accurate in recording the average pace (it can be done either cycling or walking while running). Indeed, it seems that the various smartwatches are very different on this point!

[@Jogi-1111]

I love and appreciate your work in analysing the accuracy of modern watches, but I made an astonishing experience, that might be worth to think about regarding sleep tracking. When checking your experience of sleep tracking of the Amazfit GTR3, that watch is pretty perfect (and even better than the Withings Sleep Analyzer) regarding only the total or complete(!) sleep time, meaning the time between falling in sleep and awakening. And my experience is exactly the same: That GTR3 is pretty perfect when measuring the complete(!) sleep time. But wait: This Huawei Band 7 on the other hand is measured by you as one ot the worst regarding complete(!) sleep time. So far, so good. One could resume, that you should not take this Huawei Band 7, even if you are fine with only the complete sleep time. But now my experience: I wear the Amazfit GTR3 on my left hand and the Huawei Band 7 on my right hand now for a week, and I noticed, that both watches measured always(!) the same (+/- 1min) total sleep time ! How is this possible ? When checking a lot (but not all) of your videos regarding the exact tracking of sleep stages, I noticed, that every(!) watch has some problems, measuring the right stages of sleep. Even the best systems like the Withings Sleep Analyzer lacks a lot of accuracy: None of them tracks sleep stages in a range of 80% or better. Only regarding total (or complete) sleep time, there are a few watches (like the GTR3), which are pretty near (say more than 98%) to the actual complete sleep data, regarding your measurements. So how is it possible, that you measured the Huawei Band 7 different than the Amazfit GTR3, but I noticed, that they track complete(!) sleep exactly the same ? Well - maybe we do have different sleep habbits. And some watches do track well the sleep of one person, but have trouble, tracking the sleep of an other person. My conclusion: Tracking sleep stages is still mostly only a rough estimation, tracking total or complete sleep might be working much better, but even there, the accuracy might be different from person to person.

[@filmgirlpipes]

Wow, Rob! Your videos are incredible, and so helpful. Thank-you so much. One thing that I find frustrating with this Huawei band is that it does not count side steps or backward and forward motions that are not full steps. For example, when I am working on our canning line, I am constantly side stepping and back stepping. I have done that for hours at a time without the Huawei band logging a single step! It seems a little unfair since I am always getting a workout! My Fitbit always logged those steps. It's a rather big anomaly that I thought you might find interesting for future videos! On the exact same type of work day, the Fitbit would log over 20,000 steps while the Huawei Band 7 will give me 3,700! Why the big difference? I know that the Fitbit tends to give you some free steps, but that discrepancy is crazy. Is it in the type of sensor used?

I am quite happy with the Huawei Band 6 I bought in March 2022, your review help me decide... that and also a great deal at 30€. I did not get it for the sleep tracking so the under performance do not bother me much, that mentioned not being able to set up the sleep time range is bad and if you are working on a night shift the band is 100% useless as the sleep time is considered as naps and you do not have any details. But again for what I got it (steps, some activities, heart rate etc...) I am ok and will not upgrade to the 7, maybe to the Watch Fit but I like a small wearable device as I am always wearing an automatic watch and will never stop. Also as an iOS device user, I have to say that you do not get the SMS and that's a shame.

I'm surprised Band 7 didn't outperform Band 6. That's a pity! Still, there is a chance after updates Band 7 performance will be improved Thanks for a great review!

Sadly Huawei watches cannot be used with Sleep for Android as I realized a bit too late after buying. Their sdk does not allow you to interact with the watch directly, only indirectly through their Health app, meaning you can't use the watches data on its own but only the already process data

Just a personal advice. I got the band 6 (maybe it is the same with the band 7). I used it in the pool and it broke, probably one of the connectors with the button. So maybe be careful with that. Thankfully Huawei replaced mine when I took it to their service. There is a video on youtube of a guy that says clicking the button under water damages it (wich is what I did). He also says that his band revived after drying out for a few days (mine did not revived, it got stuck in a reboot loop). But who knows, maybe mine was just a defective device. Other than that it has been a good heart rate sensor and sleep monitor (just for the total sleep time and nap time). Also, thanks Quantified Scientist, you make a great job here, next time I'm definitely buying whatever you recomend.

China brand trackers are never meant to go under inside water, no matter what they claim.
