Xiaomi’s modern fitness bracelet has long since ceased to be just a pedometer, becoming a full-fledged personal assistant for monitoring health and activity. Smartphone owners often underestimate the functionality of these compact devices, using only a small part of their potential. In this article, we will discuss in detail what exactly the tracker from the Chinese giant can solve and why it remains the market leader.
The main value of the device lies in the synergy of hardware and software Mi Fitness (formerly Zepp Life), which is a bundle of gadgets and applications allows you to collect detailed statistics, analyze trends and get personalized recommendations. If you are just planning to buy or already own a device, but do not know all its secrets, this material will be a comprehensive guide for you.
With each new generation, whether it’s the Mi Band 7, Mi Band 8 or the latest Mi Smart Band 9, the manufacturer adds new sensors and algorithms. AMOLED-screen-support NFC for payment, built-in GPS And even the ability to control the camera of a smartphone.
Monitoring of physical activity and training
The fundamental task of any tracker is to count steps, and here Xiaomi's algorithms are highly accurate thanks to the accelerometer and the gyroscope. However, modern models offer much more than just numbers. The built-in P.A.I. (Personal Activity Intelligence) analyzes your activity and gives a score, showing whether you moved enough to maintain a healthy cardiovascular system.
There are over 150 training modes available for athletes, and the device automatically recognizes running, walking and rowing, starting recording activity without the need for manual activation. With a GPS module (built in or connected via a phone), the tracker builds a precise route, measures pace, stride length and ground contact time.
- 🏃♂️ Automatic determination of activity type and calorie counting taking into account pulse zones.
- 🏊♀️ Waterproof up to 5 ATM allows you to swim in the pool and track the style of stroke.
- 🚴♂️ Support for external sensors and data synchronization with popular sports apps.
Importantly, advanced metrics such as VO2 Max (maximum oxygen consumption) and recovery time are available for professional athletes, which help to adjust the training plan, avoiding overtraining and injury.
Health monitoring system 24/7
One of the key features to look out for is around-the-clock vital signs monitoring, and the Heart Rate optical sensor takes your pulse every few minutes, plotting detailed changes throughout the day and night, and allowing you to notice abnormalities like resting tachycardia.
Blood oxygen monitoring (SpO2) has become particularly important in recent years, and can be used to measure a person’s oxygen levels or to automatically monitor them during sleep, warning of a critical drop in saturation.
⚠️ Note: The health data provided by the fitness bracelet is informational in nature, is not a medical diagnosis and cannot replace a doctor's consultation or professional medical equipment.
Sleep quality is analyzed in striking detail, and the system distinguishes between deep, light and light phases. REM-It also records the moments of daytime sleep, and it's based on this data to assess the quality of rest and give advice on how to improve your sleep patterns.

Smart Notifications and Smartphone Management
The fitness bracelet acts as the second screen of your smartphone, allowing you to stay informed without taking your phone out of your pocket. The app configures notification filtering: you can choose which apps will display messages on your wrist and which ones will ignore.
In addition to text messages from messengers and social networks, the device displays information about incoming calls. In models with a microphone and speaker (for example, Mi Band 8 Pro or new versions), even a conversation through the bracelet is possible, although the quality of communication depends on the distance to the phone.
- 📱 Music control: switching tracks and adjusting volume on a connected smartphone.
- 📸 Remote camera shutter: ideal for group photos or tripod selfies.
- 🔍 Phone search: the feature makes the smartphone ring loudly, even if it is in silent mode.
Also available is a vibration alarm function that wakes the wearer up without disturbing others, especially when traveling or living together, and the Vibromotor is quieter in the new models, but more tangible, which improves the tactile perception of notifications.
Comparison of models: Mi Band 7, 8 and 9
When choosing a device, the question often arises: What is the difference between generations? Each new model brings improvements in screen, autonomy and sensor set, and to make it easier for you to determine, we have prepared a comparative table of key characteristics.
| Characteristics | Mi Smart Band 7 | Mi Smart Band 8 | Mi Smart Band 9 |
|---|---|---|---|
| Screen diagonal | 1.62" AMOLED | 1.62" AMOLED (60 Hz) | 1.62" AMOLED (60 Hz) |
| Autonomy | 14 days | 16 days | 18 days |
| Firming | Classical. | Quick-release (magnetic) | Quick-release (magnetic) |
| Case material | Plastic. | Plastic/Metal (Pro) | Aluminum alloy |
Since the eighth model, the manufacturer has introduced a system of fast fast fastening of straps Quick-release, which allowed to turn the bracelet into a pendant or mount for sneakers. The ninth model received a fully metal body, which increased the strength and premium sensation on the arm.
☑️ What to look at when choosing a model
If you want to keep your screen on (AOD) at all times, you should consider that this feature consumes a lot of battery life. In new models, AOD optimization is improved, but the difference in autonomy between generations is still noticeable when used actively.
NFC, Payment and Autonomy
Wrist pay remains a hot topic, with NFC models allowing you to pay for purchases at terminals, but it is important to understand regional limitations: in Russia, Xiaomi’s Mi Pay bracelet functionality has not been officially supported since 2022, although in other countries (such as China or Europe), this feature works fully.
Nevertheless, NFC-The tag can be used for other tasks, such as unlocking a smart lock or connecting quickly to smart home devices, making the wristband a universal access key in the Mi Home ecosystem.
⚠️ Note: Before buying the version of the NFC Make sure to check with the seller for which region the device is released. The global version may not have working payment services in your country.
In terms of autonomy, the lithium-polymer battery, with a capacity of about 190-200 mAh, provides up to two weeks of normal operation, and is charged through a magnetic connector that is quickly and reliably fixed on the contacts.

For maximum charge savings, turn off constant monitoring SpO2 Reduce the frequency of pulse measurement to 10 minute 30 It'll keep you busy. 3-4 day-day.
Customization and personalization of the interface
The visual part is something you interact with all the time. The dial store in the Mi Fitness app has thousands of options. You can choose a static image, animated background, or even an interactive dial with mini-games.
