Modern wearables have evolved from simple pedometers to powerful wrist-mounted analytics centers, and the Xiaomi Mi Band 6 is a prominent representative of the available segment. Users are often interested not just in the presence of features, but in how accurately they work and what information the device is able to provide in real time. Understanding what the screen displays and what hidden computing the processor produces is critical for those who monitor health.
Unlike its predecessors, the sixth generation has been significantly increased. AMOLED-It's a display that allows you to output more data without having to constantly go to your smartphone. The key feature of the Mi Band 6 is the introduction of an oxygen sensor (SpO2), This change has dramatically expanded the range of metrics available for daily monitoring.
In this article, we will discuss in detail what metrics the user sees, how to interpret the values obtained and how much you can trust the built-in algorithms. You will learn about the nuances of optical sensors, the features of tracking various activities and how to properly configure the device to obtain the most accurate results.
The main interface and screen are always on (AOD)
The first thing the owner encounters after activating the device is the main dial. Xiaomi Mi Band 6 offers a huge library of designs, but the information saturation of each of them varies. The base screen usually shows the time, date, current step and pulse, but the user can customize the output data through the Mi Fitness or Zepp Life application.
It's important to note that AOD (Always On Display) is a feature that doesn't turn off the backlight completely, but instead goes into energy-efficient display mode, showing only the time and date in dim pixels, allowing you to look at time with a single movement of your wrist without activating the bright screen, which is especially convenient during meetings or in the cinema.
⚠️ Attention: Continuous activation of the mode AOD It reduces battery life significantly, and if you want to maximize the duration of your work without recharging, you might want to use the wrist lift function.
In addition, swipes on the screen provide access to widgets that show current weather, atmospheric pressure and alarm status. Navigation is implemented intuitively: vertical swipes change functional blocks, and horizontal swipes allow you to switch between dials or running workouts.
Monitoring of heart rate and oxygen saturation
One of the main tasks of the tracker is to measure physiological parameters. PPG (PPG The heart rate sensor, located on the back, reads blood flow up to 50 times per second in real time, and it can not only show the current pulse, but also plot its change throughout the day, highlighting areas of rest and activity.
Special attention should be paid to the SpO2 measurement function, which uses red LED light to determine the percentage of oxygen saturation of hemoglobin, which is critical for people who are engaged in high altitude climbing or those recovering from respiratory diseases, the measurement can be manually run or set up automatic monitoring during sleep.
- 📊 Pulse Zones: The bracelet automatically determines which intensity zone you are in (warm-up, fat burning, aerobic, anaerobic, maximum).
- 🔔 Notifications: The vibration signal will alert you if the resting pulse exceeds the user’s limits (minimum or maximum).
- 🌙 Night monitoring: the device can measure the pulse and SpO2 Every 30 minutes while sleeping without disturbing the wearer with a bright screen.
You have to understand that optical sensors are sensitive to external factors, that tattoos on the wrist, too weak fit of the strap or low skin temperature can distort the readings, and that you need to fasten the bracelet tightly but comfortably above the wrist bone to get the correct data.
💡
For the most accurate measurement of SpO2, place your hand with your bracelet on the table and freeze for 15-20 seconds. Muscle movements can knock off the saturation calculation algorithm.
Tracking of physical activity and sports modes
The Xiaomi Mi Band 6 supports 30 professional training modes, making it a versatile tool for athletes. When you start the mode, the screen displays a timer, current pulse, number of calories burned and, depending on the type of activity, additional metrics such as pace or distance (when you connect to the GPS smartphone).
PAI (Personal Activity Intelligence) transforms complex heart rate and activity data into a single, comprehensible estimate. Instead of chasing an abstract 10,000 steps, the system recommends maintaining a certain level of PAI to stay fit, making it easier for people without athletic training to plan for their workloads.
For swimmers, support for 5 ATMs is important, meaning that you can dive to a depth of 50 meters. The bracelet recognizes swimming style, calculates strokes and SWOLF (swimming efficiency). After swimming, the data is synchronized with the smartphone, where you can see a detailed map of movement and distribution of effort.
☑️ Preparation for the marathon with Mi Band 6
There's a special mode of operation for runners, although there's no built-in bracelet. GPS-It uses the data of the smartphone to build the track, and it focuses on biometrics. The screen shows the current pace, which allows you to adjust the speed of movement without having to take the phone out of your pocket.
Analysis of sleep quality and recovery
Sleep is the foundation of recovery, and the Mi Band 6 approaches its analysis in a comprehensive way: the device tracks not only duration, but also phases: REM, light, deep and wakeful periods. The algorithm analyzes movement and heart rate to determine how well the body rested.
The app generates detailed statistics to see a sleep score and personalized advice, such as if the deep sleep phase was too short, the system may recommend changing the bedtime or reducing stress levels before the night, and tracking sleep breathing quality to help identify potential problems.
| Parameter | What shows | Normal value. |
|---|---|---|
| Deep sleep. | Physical Recovery Phase | 15-25% of total time |
| REM-sleep | The phase of information processing by the brain | 20-25% of total time |
| Awakenings | Short-term moments of activity | Minimum amount |
| REM-sleep | The phase of information processing by the brain | 20-25% of total time |
Daytime nap is also supported, but algorithms may not be able to describe phases in detail if the rest lasts less than 3 hours. For maximum accuracy of the night analysis, it is recommended to wear the bracelet tightly so that the sensor does not lose contact with the skin during active movements in bed.
Stress, Breathing and the Female Cycle
Psychological health is directly related to physical health, so stress monitoring is included in the function. By analyzing heart rate variability (HRV), the bracelet calculates the stress index. High values can indicate fatigue or emotional overload.
When high stress levels are detected, the device will offer a breathing exercise, which will show an animation of an expanding and narrowing circle, rhythmically guiding the user through the cycle of inhalation and exhalation, which helps to quickly lower the pulse and restore calmness in 1-2 minutes.
⚠️ Attention: The stress indicators on the bracelet are indicative and cannot replace professional medical diagnosis or counseling for chronic problems.
Menstrual tracking is available for women, and the app allows you to enter data on the beginning and end of your cycle, as well as your symptoms. Xiaomi Mi Band 6 will be a pre-warning reminder of your expected date, helping you schedule and exercise, and all data is stored locally and in the cloud of your account.

Notifications, music and other functionality
Beyond health, the bracelet takes on the role of a second screen for a smartphone, broadcasting notifications from calls, SMS, messengers (WhatsApp, Telegram, Viber) and social networks. The text of the message is displayed in full, supporting emoji and Cyrillic, which allows you to quickly assess the importance of notification without looking for a phone.
Multimedia control allows you to switch tracks, pause music and adjust volume right from your wrist, which is especially convenient during training when the phone is in your bag or on your belt, and also implements a phone search function: on command from the bracelet, the smartphone will start to ring loudly, even if it is in silent mode.
- 📸 Remote camera: the bracelet works as a shutter button for the smartphone camera, allowing you to take group photos.
- ☔ Weather: displays current temperature and forecast for 3 days, updated when synchronized.
- 🔋 Battery status: shows the charge of both the bracelet itself and the connected smartphone.
There is also a sedentary feature that vibrates if the user has not moved for an hour, a simple reminder that helps to stretch and avoid stagnation of blood, which is especially true for office workers.
