How to use the Xiaomi Smart Band 8 fitness bracelet: from setup to advanced features

Xiaomi Smart Band 8 is not just a pedometer, but a full-fledged assistant for health, sports and everyday tasks. Compact, stylish and feature-rich, this bracelet has become one of the most popular gadgets in the Xiaomi line. However, many users use it only 20-30% of the capabilities, limited to basic functions like counting steps or time. Meanwhile, the Smart Band 8 has much more to do, from monitoring sleep with phase analysis to controlling music on a smartphone and even paying for purchases via NFC (in the Pro version).

In this guide, we’ll take everything you need to know about a wristband, from first switching on and syncing with your phone to hidden features that aren’t mentioned in the official manual, how to wear the gadget correctly for accurate measurements, what settings optimize battery consumption, and how to use the Smart Band 8 for training, sleep and even work, and also, we’ll take a look at typical beginner mistakes that spoil the experience of use.

Whether you've unpacked the bracelet or you've been wearing it for a week, there's something new in this article for any level of training, and for convenience, we've divided the material into thematic blocks, so you can go straight to the section you're interested in or study everything in order.

1. Preparation for use: unpacking, charging and first activation

Start by unpacking the bracelet. In the box with Xiaomi Smart Band 8 you will find:

  • πŸ“¦ The fitness bracelet itself with a strap (color depends on the version chosen).
  • πŸ”Œ Magnetic charging cable (USB-Type-C)
  • πŸ“„ Short instructions in several languages (including Russian).

Before you turn on the bracelet, fully charge it.Although there may be a small charge in the box, it is better to start with 100% - this will help avoid a sudden shutdown during settings. Connect the magnetic cable to the bracelet (the contacts are on the back of the case) and to any USB- port (charging from a computer, powerbank or adapter 5V/1A). Full charging takes about 1.5–2 hours.

After charging, press and hold the touch button on the bracelet screen for 3-5 seconds until the Mi logo appears. This is a sign that the device is turned on. If the screen does not respond, check if the cable fits tightly to the contacts - sometimes the bracelet does not turn on due to insufficient charge (less than 5%).

⚠️ Warning: Do not use adapters with voltages higher than 5V (e.g., from fast charging of smartphones) to charge. This can damage the bracelet battery and shorten its life.

2. Installation and configuration of the Mi Fitness application

Without the official Mi Fitness app (formerly Mi Fit), the bracelet will work like a regular watch - without synchronizing data, notifications or advanced features.

  • πŸ“± Android: from Google Play.
  • 🍎 iOS: From the App Store.

After installation:

  1. Sign up or sign in to your Xiaomi account (if not, create it via email or phone number).
  2. Click Add Device β†’ Select Bracelet β†’ Mi Smart Band 8
  3. Allow the app to access notifications, location, and contacts (necessary for proper operation).
  4. Follow the instructions on the screen: confirm the pairing on the bracelet (button on the screen) and wait for synchronization.

If the bracelet does not find the application:

  • πŸ”„ Reboot both the bracelet and the smartphone.
  • πŸ“Ά Make sure your phone is on Bluetooth and Geodata.
  • 🚫 Turn it off. VPN Power saving modes – they can block the connection.

β˜‘οΈ Checklist before first synchronization

Done: 0 / 5

Important: After the first synchronization, update the bracelet firmware through the Device Profile β†’ Software Update. New versions fix bugs and add features (for example, support for new types of workouts).

3. Basic functions: screen, notifications and control

The Smart Band 8 screen is touch-sensitive, but it's not like a smartphone. Here are the basic gestures:

  • πŸ‘† Swipe up/down: scroll through menus or notifications.
  • πŸ‘ˆ Swipe left/right: switch between screens (time, steps, pulse, etc.).
  • πŸ”˜ Press the button: select a menu item or go back.
  • πŸ”„ Long-term pressing: turning on/off the bracelet or resetting (if getting stuck).

To set up the display of notifications:

  1. Open Mi Fitness β†’ Device Profile β†’ Notifications.
  2. Turn on the β€œNotifications” switch and select the applications you want to see alerts from.
  3. Set up the display style: full text or only the app icon.

The bracelet vibrates when incoming calls, messages and alarms. To turn off vibrations for a particular application (for example, for social networks at night), use Do Not Disturb mode:

On the bracelet: Swipe down β†’ Moon sign (sleep mode)


In the app: Device profile β†’ Do not disturb β†’ Schedule setting

⚠️ Warning: If notifications don't come, check: πŸ“΅ Is Bluetooth enabled on the phone. πŸ”• Is the Mi Fitness app added to the notification blacklist (on Android: Settings β†’ Applications β†’ Mi Fitness β†’ Notifications). πŸ”„ Does a reboot of the bracelet (sometimes helps).

πŸ’‘

To quickly find the phone, swipe down on the bracelet and tap the phone icon. The smartphone will emit an audible signal (even if it is in silent mode).

4. Health monitoring: pulse, sleep and stress levels

The Smart Band 8 is equipped with sensors to track key health indicators around the clock.

FunctionHow it worksHow to turn on/set up
Pulse measurementThe PPG sensor tracks your heart rate every 5 to 30 minutes (set up).Mi Fitness β†’ Profile β†’ Heart Monitoring β†’ Measurement Frequency
Sleep trackingAnalyzes the phases of sleep (deep, light, REM), awakening and daytime sleep.To be precise, wear the bracelet on your non-working hand.
Oxygen levels (SpOβ‚‚)Measures blood oxygen saturation (normal: 95-100%).On the bracelet: Swipe to the screen SpOβ‚‚ β†’ Start
Stress levelEvaluates heart rate variability (HRV) and activity.Mi Fitness β†’ Profile β†’ Stress level

For accurate pulse measurement and SpOβ‚‚:

  • 🧘 Wear a bracelet 2-3 fingers above your wrist (tightly but not compressively).
  • πŸ›Œ Measure SpOβ‚‚ in a calm state (sitting or lying down).
  • ⏱️ Wait for the stabilization of the readings (usually 10-15 seconds).

The sleep data is collected automatically, but can be manually adjusted. For example, if you forgot to wear the sleep bracelet at night, add a sleep record to Mi Fitness β†’ Sleep β†’ Add manually. To improve sleep quality, the app makes recommendations based on your data (for example, go to bed earlier or reduce the time before screens before bed).

What to do if the bracelet shows an unrealistically high pulse?
If the pulse on the bracelet screen suddenly jumps to 180-200 beats (while you are calm), most likely, the sensor is not tightly attached to the skin or on the arm a lot of hair. Wipe the sensor and wrist, put on the bracelet tighter and re-measure. If the problem repeats, update the firmware or reset the bracelet settings.

5. Training and sports functions

The Smart Band 8 supports over 150 training regimes, from walking and running to yoga and boxing.

  1. On the bracelet, swipe to the right to the Training screen.
  2. Select the type of activity (e.g., β€œRunning Outside”).
  3. Press the button to start. The bracelet will start tracking the time, pulse, calories and route (if the phone's GPS is connected).

For accurate tracking of running or cycling:

  • πŸƒ Wear the bracelet on your work arm (for running) or fasten it on your sleeve (for a bicycle).
  • πŸ“Š After training, the data is synchronized with the application, where you can see the route map, pace and other metrics.
