What Xiaomi bracelet does: a full guide to the functions of a fitness tracker in 2026

Xiaomi’s smart bracelets are no longer just pedometers — they’re now full-fledged assistants for health, sports and everyday tasks. Since the first Mi Band was released in 2014, the functionality of the devices has grown dramatically, from basic step count to stress monitoring, ECG (in top models), and even smart home management through the Mi Home. But many users still use the bracelet only 20% of its capabilities.

In this article, we will take a look at what Xiaomi’s 2026 bracelet does, from obvious features to hidden “chips” that aren’t written in the official instructions. You’ll learn how the tracker analyzes your sleep, why heart rate data may differ from medical devices, and how to use the bracelet to control your smartphone camera at a distance of up to 10 meters without lags.

1. Health monitoring: what exactly is the bracelet tracking

The main highlight of Xiaomi bracelets is a comprehensive health analysis that works 24/7. Let’s figure out what parameters the device tracks and how much they can be trusted.

The most popular function is pulse measurement. PPG-A sensor that analyzes changes in blood flow under the skin, and new models (starting with the Mi Band 7) have added the TruSeen algorithm.™ 4.0, which reduces the error of movement, such as when running or cycling, the data will be more accurate than the old versions, but it is important to understand that the bracelet does not replace medical equipment. If you have arrhythmia or other serious heart problems, it’s best to use specialized devices (such as the Apple Watch Series 8).+ ECG-certified).

• 🩺 Heart rate (HR): Measured every 5 to 30 minutes (adjusted in the app) or manually on request.
• 😴 Sleep quality: fixes the deep, light and REM-Mi Band 8 adds analysis of daytime sleep (if you take 20 minutes of naps during the day).
• 😓 Stress level: Estimated by heart rate variability (HRV) from 1 to 100, where 1–30 is relaxed, 70+ — stress.
• 🩸 Oxygen saturation of the blood (SpO₂): It's especially important for athletes and people with breathing problems, 95 to 100 percent, and if the bracelet is below 90 percent for a long time, you should see a doctor.

One of the most controversial aspects is blood pressure measurement, which some models (such as the Xiaomi Smart Band 7 Pro) have a function to assess pressure, but it works indirectly: the bracelet analyzes heart rate and sleep data, and then gives a rough result. This is not a medical measure, the error can be ±15 mm Hg For accurate data it is better to use a tonometer.

⚠️ Warning: If the bracelet consistently shows heart rate above 100 beats per minute at rest or SpO₂ If you are below 92%, it can be a sign of a health problem.

2.Sports and fitness: what training bracelet supports

Xiaomi bracelets are positioned as active-life devices, and here they are really strong. Even the basic Mi Band 6 supports 30.+ The tracker does not just count the steps, but analyzes the intensity of the load, calorie consumption and even exercise techniques (for example, running or swimming).

The automatic recognition of workouts is particularly useful, because the bracelet detects that you have started running, cycling or swimming, and it triggers the appropriate mode, which is convenient if you forgot to turn on manual tracking. However, automatic recognition does not work perfectly: for example, it can take brisk walking for running or vice versa. In such cases, the data can be edited later in the Mi Fitness app (formerly Zepp Life).

For runners and cyclists, the following functions are especially useful:

• 📍 GPS-Track: In models with built-in GPS (For example, Mi Band 8 Pro, the route is recorded without being tethered to a phone, which is convenient for races in the forest or park, where communication may be lost.
• 🏃 Track analysis: Records stride length, pace, ground contact time, and even left/right leg balance, and helps improve performance and avoid injury.
• 💦 VO₂ max: Maximum oxygen intake is a key indicator of endurance: 40–50 ml/kg/min for men, 35–45 for women.

Water resistance is important for swimmers. All Xiaomi bracelets have 5 protections ATM, But there's a caveat: in a pool of chlorinated water, you don't want to take the bracelet for long, because an aggressive environment can damage the silicone strap.

💡

To increase accuracy GPS-Before training, you can set your smartphone to "High Accuracy" in your location settings, which will help the bracelet find satellites faster.

3.Smart features: from music management to shopping

Beyond health and sports, Xiaomi bracelets can perform many everyday tasks, and many users are unaware that their tracker can:

• 🎵 Control music: Switch tracks, adjust volume and pause - right off the bracelet. Works with most players (Spotify, YouTube Music, Apple Music).
• 📸 Remote Photography: Click on the camera icon in the wristband menu and it will open the camera app on your smartphone.This is convenient for selfies or group photos.
• 🔍 If your smartphone is lost at home, the bracelet will make it emit a loud signal (even if the phone is silent).

• 🏠 Manage a smart home: Through the Mi Home app, you can turn on the lights, adjust the temperature of a smart air conditioner or run a robot vacuum cleaner.

One of the most underrated features is fast response to messages. If you have Android, the bracelet can show notifications from messengers (WhatsApp, Telegram, Viber) and allow you to respond with template phrases (for example, “I’m on the way”, “I’ll be back later”). On iPhone, this feature works only with reading notifications.

Another feature is Do Not Disturb mode, which can be set to a schedule (like 23:00 to 7:00) or manually activated, which does not vibrate at notifications, but keeps track of sleep and pulse, useful for those who do not want to wake up from night messages.

4. Battery and autonomy: how to extend the life of the bracelet

One of the key advantages of Xiaomi bracelets is long work without recharging. for example, Mi Band 8 in basic mode (no recharging). GPS And it's a very long time, and it's a very long time, and it lasts up to 16 days, and it lasts 5-7 days with active use, but many users are faced with the fact that the battery goes down much faster.

The main "eaters" of charge:

• 🔍 Continuous pulse monitoring: If the measurement is turned on every 1-5 minutes, the battery consumption increases by 30-40.
• 📡 Connection to GPS: In models with built-in GPS (For example, Mi Band 8 Pro, one tracked training session eats up to 15% of the charge.
• 📱 Frequent notifications: Each vibration in a new message wastes energy. Turn off unnecessary notifications in the bracelet settings.
• 🌡️ Measurement SpO₂ Useful function, but if you do not critically, turn it off - it will save up to 20% of charge.

To extend your autonomy, follow these tips:

1. Reduce your pulse rate to 30 minutes (in the Mi Fitness app, go to Profile). → The device → PERSON Settings).
2. Turn off automatic training recognition if you are not using it.
3. Use dark wallpaper on the screen (AMOLED-The display uses less energy on black).
4. Turn off the bracelet while charging your smartphone – this will reduce the background energy consumption via Bluetooth.

If the bracelet starts to discharge too quickly (for example, it lasts less than 2 days), check the following points:

• 🔌 Charging cable: Use only original or certified cable. Cheap analogues can damage the battery.
• 📲 Firmware: Update the bracelet software through the Mi Fitness app. Newer versions often optimize energy consumption.
• 🌡️ Temperature: Do not leave the bracelet in direct sunlight or in heat (above) +40°This reduces the battery life.

⚠️ Note: If the bracelet stopped holding charge even after optimizing the settings, the battery may be worn out. On average, the battery in the Xiaomi bracelets is designed for 300-500 full charging cycles (about 2-3 years of active use.
