Xiaomi Mi Smart Band 7 test: our opinion

Xiaomi took advantage of the Paris event to unveil a host of new products, including the Mi Smart Band 7. A connected bracelet with various health sensors, 110 sports modes, a larger screen, and a bigger battery (among other things).

The changes are minor compared to the Mi Smart Band 6 and result in a higher suggested retail price. Is the investment justified? This is what we want to see after wearing it for almost 1 month on the wrist.

How did we test Xiaomi Mi Smart Band 7?

The linked bracelet was provided to us by the brand during a press conference. We then installed it on our Pixel 6 and used it for almost a month. The bracelet basically served us to measure health, get our (many) daily notifications, and wake up.


Which other connected bracelet is more like a Xiaomi bracelet than another Xiaomi bracelet? Put side by side, it will be hard for you to tell the Mi Smart Band 6 and 7 apart unless you really pay attention to their size. The old model does measure 46.5 x 20.7 x 12.25mm versus the newer’s 47.4 x 18.6 x 12.7mm, but the design remains the same.

Thus, Mi Smart Band 7 has a 1.62inch AMOLED screen (192 x 490 pixels), which is 25% larger than Mi Smart Band 6. A welcome change in daily life as it allows you to read notifications and navigate through the menu. .The screen brightness, which has increased from 450 nits to 500 nits, lacks the power to counter strong sunlight. No problem reporting at night.

Although the bracelet is readable, the screen lacks brightness in direct sunlight.

Among the new products, we also note the presence of a battery with a capacity of 180 mAh versus 125 for the previous model (we will return to this in more detail below). The improvements mentioned above result in a slight weight gain (13.5g vs 12.8g) that is not noticeable throughout the day.

As for the black silicone strap that came with our test model, it is the same as on previous generations of the Mi Smart Band. It is pleasant to the touch, nonslip, and the clasp holds securely. Xiaomi offers options on its store and many other alternatives are available online. Changing it is also very easy to do: just press it with your thumb to take it out or put it back in.

A simple change is like a pie.

The bracelet is water resistant up to 5 ATM (50 meters) and can therefore follow you in the pool and shower, even if using the screen after getting wet is next to impossible.

Required Application

Once again, you will have to go through the Mi Fitness app to take full advantage of your connected wristband. After completing the registration and entering data about your morphology (height, sex, weight), an interface opens in front of you.

Your health data (heart rate, number of steps, calories burned, stress, standing time, PAI, etc.) is stored in the “Health” tab, from the tab of the same name you can start training and find system settings. in the device. You can select the features you want to see on the screen of your bracelet, limit notifications, activate an alarm, or even easily change the wallpaper to your liking. It is also possible to download from the application.

Simple and effective application.

No major changes compared to the Mi Band 6, but it must be said that the display was already quite sharp and secured, so why change the winning team?

at your fingertips

Navigating the AMOLED screen is always swipe, i.e. sliding your finger from left to right or vice versa to get to your favorite widgets. In our case, the weather and the music player. Swipe up from the bottom to access all watch features (flashlight, timer, exercise, alarm, etc.) and settings. Finally, swiping down from the top reveals a place dedicated to notifications.

The device always responded during our test, even when the battery was low. However, the animation is not smooth, as if the image is grabbing our finger with each slide, and it takes a little reaction time before moving from one menu to another. There is nothing outrageous for a connected bracelet, but this must be emphasized.

Who can do more can do less

If Xiaomi Mi Smart Band 7 fulfills its function as a modern beeper, it has popular sports and medical features such as heart rate analysis, maximum oxygen consumption (VO2 max) and even blood oxygen saturation (SpO₂).. Various modes also allow you to follow menstrual cyclehis sleep stages where breath.

Detailed monitoring of your activities can be found in the Mi Fitness app. However, if your smartphone is not at hand, you can always check the latest data collected right on your bracelet. While the screen is too small to integrate a virtual keyboard, we would have liked to be able to send voice messages, or at least prerecorded messages, from the Mi Smart Band 7.

The Chinese brand boasts 110 sports modes stored in Training, from tennis to hiking, walking and even chess. However, we did not find this feature intuitive. If your sport is not highlighted in the app, you will have to search for it in subcategories with sometimes random translations, such as “Boxing”, which includes martial arts, or “Ball Sports”, in which we find tennis and football.

We then asked Xiaomi why this important choice of diversification: “Although the two modes may have much in common in the monitoring and implementation algorithm, one of the main reasons for the difference is to allow users to quickly find the activity they are engaged in easily and effortlessly. confusion.”

The information collected then varies from one sport to another. In football, you can have time, calories burned, and heart rate, but nothing more. However, in swimming, you can get the number of breaststrokes, laps, or even your own pace. There is also no coach or session to follow.

Finally, note that GPS and NFC are still missing from the game.

Without a charger, you can leave with peace of mind

Xiaomi managed to install a 180 mAh battery versus 125 on the previous model. With intensive use, like ours (Twitter, Facebook, SMS notifications, calls, sleep analysis, etc.), battery life drops to 1 week, while the manufacturer calculates twice as much. However, this assessment remains correct and avoids having to recharge the device every evening. If you have fewer connections than us, autonomy can increase to more than a week. Please note that the power saving mode will allow you to increase the number of hours of use in exchange for a reduction in operating time.

Expect a good week of battery life with heavy use.

After completely draining the battery, we noticed that from 0 to 100% was completed in 2 hours and 30 minutes using a proprietary USB cable in a 5V outlet. During your lunch break, your bracelet will be updated.

Competition update

If Mi Smart 7 and 6 are similar in terms of design, this also applies to features and technical data. And since previous generations are less expensive, it’s legitimate to wonder if the extra investment on your part is worth the effort.

If GPS is important to you and you absolutely need a connected wristband, we recommend the Fitbit Charge 5, even if it doesn’t have a music player (don’t ask us why Mark was chosen).

So, shall we buy?

Pleasant to wear, easy to use, quite autonomous and with a lot of sensors… we can say that Xiaomi Mi Smart Band 7 has done its job. However, small improvements made to this model have led to an increase in its price. We prefer to recommend its predecessor, the Mi Smart Band 6, which costs much less and offers similar features, in anticipation of possible discounts.
