Xiaomi Mi Band 7 fitness bracelet review

Fitness bracelets (aka fitness trackers) from Xiaomi are well-deservedly popular: they are cheap, comfortable and have a good set of functions.

I have been closely following the fitness bracelets of this manufacturer since the 3rd version: they are developing well and I liked the previous, sixth, model – compared to the fifth version, the improvements were quite noticeable. However, this fitness bracelet had certain drawbacks, which I wrote about in the review at the time.

Now a new model has appeared on the market, Xiaomi Mi Band 7. On May 24, the Chinese version was presented, and its sales, according to the company, have already exceeded one million copies.

Today, June 22, the global version of this model was released, and it is already available for purchase. This fitness bracelet was sent to me in advance, I tested it properly and in this review I am ready to share my impressions.

So – fitness bracelet Xiaomi Mi Band 7. (I don’t give a link to the official site, this model has not yet appeared there.)

As usual, we compare the characteristics with the previous model. The screen has slightly increased (1.62 “vs. 1.58”), the maximum brightness has slightly increased (500 nits vs. 450), a more efficient chipset has been installed, the always-on screen mode has appeared (finally!), The battery capacity has increased (180 mAh h versus 125), the number of tracked sports modes has seriously increased (120 versus 30), and constant monitoring of blood oxygenation has been added.

At the same time, the price not only did not increase, but even became lower (the previous model at the start of sales cost 3000-3500 rubles).

Contents of delivery

Traditional packaging. The design looks a little more interesting than before.

Package contents: a fitness bracelet with a strap, a charging cable, instructions in many languages, including Russian, and it is clear that no one ever looks into these instructions. The magnetic charging head has not changed from the previous version.

Appearance and features

The fastening of the strap has not changed here – it is as uncomfortable as before. But, by the way, it is clear that there are a great many of these straps with any attachments: both multi-colored silicone and plastic of any configuration, leather, metal, and so on. I also note that these straps are the same for all models from the 4th to this 7th model.

Well, here it is next to a typical pen for sizing. On the right is my current Garmin Venu 2 smartwatch.

This is how the bracelet sits on the hand.

Device operation

The fitness bracelet is connected via the Mi Fitness app (formerly Mi Fit). There you select “add a device”, the application will detect the bracelet and offer to connect it. Everything!

The interface language of the bracelet for the global version will be the same as the interface language for the smartphone. However, the Chinese version also has, so the Chinese version is actually not much different (only the Chinese inscriptions on the box and the language of the user manual).

Dials. There are about a hundred of them here.

Heart rate and sleep settings.

Blood oxygen and stress measurement settings.

Activity reminder.

Widget setup.

Night mode settings.

Main section “Health”. The order and number of information blocks can be configured here (in the “Show all” section).

Activity statistics, blood oxygen level monitoring.

Sleep tracking.



Calories and workout.

Stress monitoring.

Training – walking (a tracker paired with a smartphone, from where it takes information from GPS).

The display on the AMOLED matrix is ​​​​very good quality, the colors are bright, saturated. And it’s good that the display has become a little wider than the previous model – more information is placed.

Here is the previous model for comparison.

In direct sunlight, the image is at least somehow visible, but at the same time, the brightness must be manually increased to the maximum – there is no light sensor here.

The main desktop is also a dial. The dial is changed by a long press on the screen (five pieces are stored in the bracelet’s memory) or in the application. There is an AOD mode (always on screen), and it is different for each particular watch face. Here is the mode for this dial.

Swipe left-right – widgets. They can be configured in the application. I installed audio player controls, sleep and sports. Separately, I note that in the previous version there was no sleep in the form of a widget, and it was very sad. Here appeared, for which many thanks.

Swipe down from the watch face – a list of notifications, on each of which you can click and read the notifications in full.

Incoming call. You can turn off the sound or drop the call.

Starting a workout. There, swipe to the left – control the smartphone’s audio player, swipe to the right – pause, end the workout, block the screen from being pressed. After the end of the training, a general summary with information is issued.

From the dial, swipe up – icons of all installed applications. Some applications are hidden under the “More” icon. The order of applications is configured on the smartphone: you can put the most frequently used ones on top, and hide those that are not needed or used rarely under the “More” icon. Also on the phone, you can set the hiding of applications that you do not need at all.

Many applications (for example, the same “Weather”) have several screens with information that are scrolled up with a swipe up.

Installed apps: timer, activity stats, sleep, heart rate, PAI, oxygen levels, workout, workout status, workout log, activity, stress, weather, music, alarm clock, events, settings, clockwork timer, flashlight, women’s health, breathing exercises, stopwatch, find my phone.

In the settings, you can set the brightness of the display (there is no automatic adjustment here), enable the Do Not Disturb mode or set its schedule (attention, this is enabled only in the bracelet itself, not in the application!), set the seconds before the dial turns off, set the schedule for automatically turning on the screen , reset the bracelet or reboot it.

Battery Life

As usual, it all depends on the settings and usage scenarios. The manufacturer claims up to 15 days of battery life, but this means without continuous monitoring, without an always-on screen and with an average display brightness.

According to my estimates, in this mode, this fitness tracker can really live up to two weeks. But I don’t see the point of using a monitoring device with little to no monitoring as such.

If you turn on automatic heart rate monitoring, normal sleep monitoring, average screen brightness without AOD mode, then the tracker works for about 6-7 days.

In the mode of continuous monitoring of everything that is possible, advanced sleep monitoring, one or two workouts per day (there is no GPS here, so training does not noticeably drain the battery) and the included AOD mode, the tracker lives for about 3 days, which is quite normal for such mode.

A full charge of the bracelet takes approximately two hours.

Observations at work and conclusions

Of some glitches, I noticed only one: even with the reminder to warm up in the application on the smartphone turned off, this warning still worked on the tracker. It was especially “pleasant” when this warning was triggered by vibration during a siesta. But I found a way to deal with this: I had to turn on this reminder, also turn on the schedule and set the period, for example 09:00 – 09:01. And I stopped remembering.

The pulse in a calm state was determined quite accurately, and during training it showed the expected values, the pulse did not overestimate.

Sleep tracking is even better than before (although it was pretty decent in the previous version), and I was very pleased that sleep is now shown as a widget – this is very convenient for those who need to track sleep. Awakenings were also recorded quite clearly.

The definition of blood oxygenation is about the same as with other fitness trackers and smart watches. It measures more or less normally, but at times it can noticeably underestimate.

The chipset upgrade felt like it had an impact on the speed and smoothness of the interface. I will also note a clear refinement of the software: both the shell and individual applications have become more convenient and informative.

What to say about the new model? Definitely – there are clear improvements compared to the previous model, that is, this is not a cosmetic update, as it often happens.

Let’s list the advantages of the new model:

  • larger display;

  • an updated chipset that affects the smoothness of the interface;

  • modified software;

  • the emergence of the AOD mode;

  • better sleep monitoring;

  • the appearance of the sleep widget;

  • the emergence of continuous monitoring of the level of oxygenation;

  • additional sports modes;

  • more advanced monitoring of sports activity;

  • increased battery capacity;

  • Not only did the price not go up, it even went down.

A clear step up from the previous model (which was also very good), so if you are the owner of Xiaomi Mi Band 6, then it is quite possible that you should consider upgrading.

I liked the device, I liked it very much. If earlier, by definition, I could not consider using a fitness tracker instead of a smart watch, then this particular model would have more or less suited me. Although, of course, I’m not going to give up smartwatches at all: I love large screens that are clearly visible in the sun and the presence of GPS.

PS For my readers, the store gave an exclusive discount coupon BAND045 (valid from 06/27/2022 to 07/01/2022).
