Presentation

The Mi Smart Band 4 is equipped with a brand new AMOLED colour display, allowing users to view statistics, messages and fitness notifications. It also comes with a 135 mAh battery and offers up to 20 days of autonomy. In addition to the health and activity monitoring features of previous generations, the Mi Smart Band 4 now offers a swim tracking mode. Its dimensions are 46.9 x 17.9 x 12 mm for a weight of 22g.

The Mi Smart Band 4 offers a design almost identical to its predecessor, moreover the straps of the 3 are compatible with the 4! In fact, the difference is in the button under the screen, which this time is fully integrated and still touch-sensitive. Oval in shape, Band 4 is encapsulated in its soft silicone strap. On the back, there are two green LEDs for heart rate calculation, as well as the connector for recharging. Note that the latter is proprietary and works with a specific dock. Finally, Band 4 is waterproof up to 5 ATM.

Ergonomics

The Mi Smart Band 4 offers an all-new user interface for easy navigation, an auto-lock function when removed from the user’s wrist and controls for music playback on smartphones.

While the Mi Band 3 was quite austere in terms of its interface, the Mi Band 4 offers a real evolution thanks to a 0.95-inch color OLED screen that finally allows more comfort! Xiaomi also offers the possibility to download many different home screens in order to personalize your bracelet. Navigation is always done in the same way by “sliding-up” from bottom to top on the screen to access the different menus (icons) and functionalities. The button at the bottom of the screen allows you to go backwards. A “slide” from left to right also gives access to the music control, another novelty on this model. The navigation is fluid and pleasant on this new model, it is now difficult to get lost in it.

Finally, it should be pointed out that the OLED screen certainly brings a plus in the ergonomics of the interface and in the use in general, but on the other hand its readability is not as good as its predecessor, especially when there is a lot of sunshine!

Use

The Mi Band 4 is a bracelet that you use every day, it will record via numerous sensors (accelerometer, cardiofrequency meter, gyroscope) all your activity, whether it is the number of steps, calories burned or activities you might do (swimming, running, cycling, etc.), up to the analysis of your sleep. You will then find these data in the Mi Fit application which is now quite complete and all in French.

Unlike some competitors, Mi Band will not detect the type of activity you are doing, you will have to tell them first. Similarly, despite its sensors, intensive activities such as a split run will, for example, make the heart rate monitor go crazy! Also note that it is not equipped with a GPS, so you will have to do your activities with your smartphone (except at the swimming pool…). Similarly, sleep data is sometimes strange and lacking in detail. Xiaomi is still on the right track with a fairly effective product, which can be improved through updates.

So Mi Band 4 works well enough for standard use and fairly basic data, but if you really want precision, more expensive competitive products will do better.

Concerning the notifications part, this model obviously allows to receive them on a call, but also on many applications such as Whatapp, Message, etc.. Just set this directly in the Mi Fit app. The notifications that appear on the bracelet’s screen feel written in small and multiple lines, which is not very legible. Xiaomi will have work to do on that side, even if it’s better than her predecessors!

Small precision which is quite important, since the last update of the app, the v4.0.6, the bracelet we only had in English version, has been entirely switched to French!

Autonomy

Announced for about 20 days of autonomy (135 mAh battery), the Mi Band 4 will have lasted us a little less than 20 days. We have used it a lot (sport, sleep, notifications, etc.) and with less intensive use, the 20 days seems totally feasible. Recharging is done in 2 hours via the dock delivered in USB.
