Activity tracking: pedometer, calories, sports

The main function of any fitness bracelet is to monitor physical activity. Xiaomi Mi Band 2 can:

🚶‍♂️ Count steps with high accuracy (the error is not more than 5-10% with correct calibration).
🔥 Calculate calories burned based on steps, user weight, and heart rate.
🏃 Track jogging (manually or automatically if the function is enabled in the settings).
🚴 Fix bike rides (requires manual start of the mode in the application).
🏊‍♂️ Record swimming (but without style detailing – only time and calories).

To activate the tracking of sports, you need to:

Open the Mi Fit (or Zepp Life) app.
Go to the Profile section → The device → Training regimens.
Choose the right sport and press "Start".

The bracelet automatically syncs data with the app, where you can see activity charts, compare results with previous days, and set goals (e.g., walk 10,000 steps a day).

💡

If the bracelet underestimates the number of steps, try calibrating it: walk exactly 50 steps, then in the application specify this value in the pedometer settings (Profile) → Settings → Calibration of steps).

Important: Mi Band 2 does not support automatic recognition of sports (such as Mi Band 5), all workouts, except walking, must be started manually.

Sleep monitoring: how the bracelet analyzes your rest

One of the most useful features of the Xiaomi Mi Band 2 is sleep tracking, which automatically detects when you fall asleep and wake up, and analyzes the phases of sleep.

🌙 Deep sleep (most restorative phase).
🌓 Light sleep (sleep periods when it is easy to wake up).
😴 Wake up (when you wake up at night).

For accurate analysis, it is necessary:

Wear a bracelet before bedtime (preferably on a non-working arm to minimize interference).
Make sure that the application settings are enabled sleep mode (Profile) → The device → Sleep monitoring).
Do not remove the bracelet until you wake up in the morning.

After sleep, the application will appear a report with:

Total sleep duration.
Phase percentage.
The number of awakenings.
Assessing sleep quality (from 0 to 100 points).

How to improve the accuracy of sleep tracking?

To make the bracelet more accurate in determining sleep phases, avoid wearing it too loosely or too tight, optimal position is 2-3 fingers above the wrist, and it is recommended to synchronize data with the application before bedtime to avoid loss of information.

⚠️ Note: If you sleep less than 4 hours, the bracelet may not be able to record your sleep as full, and it doesn't distinguish between daytime and nighttime sleep, all data is recorded in a general report.

Measurement of pulse: how it works and how accurately

Xiaomi Mi Band 2 is equipped with an optical heart rate sensor that allows you to measure your heart rate manually or automatically.

🩹 Proper position of the bracelet (should fit tightly to the skin, but not crush the hand).
🩸 Absence of tattoos or scars at the measurement site (they may distort the signal).
🚫 Absence of sudden movements during measurement.

To measure your pulse manually:

Touch the touch button on the bracelet.
Choose a heart icon (🩺).
Wait 10-15 seconds until the sensor shows the result.

For automatic monitoring:

In the app, go to Profile → The device → Heart rate.
Enable the option of Automatic Measurement.
Choose an interval (every 30 minutes, 1 hour or only during sleep).

⚠️ Note: Mi Band 2 optical sensor is not a medical device, its readings may differ from professional equipment by 5-10 beats per minute.

Tightly fasten the bracelet on your wrist|Compare the readings with a mechanical tonometer|Measure your resting pulse (sitting for 5 minutes without moving)|Repeat the measurement 2-3 times for accuracy

Notifications and smartphone management

Xiaomi Mi Band 2 can act as a smart assistant for your smartphone.

📱 Call notifications (bracelet vibrates and shows the number of the incoming person).
📧 Notifications from messengers (WhatsApp, Telegram, Viber, etc.).
🔔 Alarm clocks (up to 10 signals can be set in the app).
🔕 Phone search (if the smartphone is lost, the bracelet will help you find it vibrationally).
🎵 Music management (pause/playback, track switching).

To set up notifications:

Open Mi Fit and go to Profile → Notifications.
Enable Call Notification and Notifications from the Apps.
Select the applications you want to see on the bracelet.

Limitations:

Hidden features and life hacks for Mi Band 2

Even years after the release, Xiaomi Mi Band 2 features useful but little-known features:

🔄 Reset to factory settings: If the bracelet is buggy, press the touch button for 10 seconds until the vibration appears.
🔋 Saving charge: Turn off automatic pulse measurement and notifications of unimportant applications – this will extend the battery life up to 25-30 days.
🎨 Changing the dial: Although there is no color screen in the Mi Band 2, you can choose from 3 options for displaying time in the application settings.
🚿 Swimming mode: activate it manually before swimming (Profile) → The device → Swimming mode) to avoid false touches of water.
🔒 Screen lock: If the bracelet is accidentally pressed in your pocket, turn on lock in the settings (Profile) → The device → Screen locking).
