Touch the button area below the display to wake the band. The main watch face appears and may show the time, date, steps, battery status, or other information depending on the selected design.
If lift-to-wake is enabled in the companion app, raising your wrist may also turn on the display automatically.
[note] If the display stays off, check the battery level and charge the band before trying again. [/note]Navigating the Menu
Swipe up or down after waking the screen to move through available functions. Common menu areas can include status, heart rate, workout, weather, notifications, and More.
The exact menu order and available entries may vary with firmware, app version, and selected settings.
Watch Face
The watch face is the main information screen. Depending on the selected design, it may show more than just the current time.
- Time and date
- Step count
- Battery level
- Heart rate shortcut or value
- Weather information
- Daily activity progress
Watch face options can be managed through the companion app when customization is available. Choose a layout that keeps your most frequently checked information easy to see.
Daily Activity
The Mi Smart Band 4 can track normal movement throughout the day without requiring a workout session to be started.
- Steps taken
- Estimated distance
- Estimated calories burned
- Active time
- Daily goal progress
- Recorded workouts
- Heart rate information collected during supported activity tracking
For a quick check, open the activity or status area on the band. The displayed values update as you move. More detailed history can be reviewed after syncing with the app.
[tip] If you use a daily step goal, check the status screen during the day instead of waiting until the end of the day to review your progress. [/tip]Sleep Tracking
Wear the band while sleeping to allow it to collect movement and sensor data for sleep tracking. After syncing, the companion app can provide a more detailed view of the recorded night.
Sleep Information
- Total sleep duration
- Approximate sleep start and wake-up times
- Light sleep
- Deep sleep
- Recorded awake periods
- Sleep trends over time
For More Consistent Tracking
- Wear the band snugly but comfortably.
- Keep the sensor in contact with your skin.
- Avoid wearing the strap so loosely that the tracker moves around.
- Keep enough battery for overnight use.
- Sync with the app after waking to review the recorded data.
Sleep information is intended as a general wellness reference and should not be treated as a medical diagnosis.
Heart Rate
The optical sensor on the underside of the tracker can measure heart rate from your wrist. Open the heart rate function from the band and keep your wrist steady while the measurement is taken.
Measurement Tips
- Wear the band about one finger width above the wrist bone.
- Keep the strap snug enough to maintain sensor contact.
- Keep your arm still during a manual reading.
- Keep the sensor area clean.
- Allow the band to settle after repositioning it before measuring.
- During exercise, a slightly tighter fit can help reduce movement at the sensor.
Workout Tracking
Workout mode records a specific exercise session separately from ordinary daily activity. Available workout types may vary with firmware or app version.
Possible modes can include walking, running, cycling, treadmill, exercise, swimming, or other supported activities.
[step] 1. Wake the band 2. Open Workout or Exercise 3. Select the activity you want to record 4. Confirm the selection to begin tracking 5. Wear the band securely during the session 6. Stop the workout when you are finished 7. Sync with the companion app to review the full record [/step]Depending on the selected activity, the band may show information such as elapsed time, distance, pace, heart rate, or estimated calories.
Notifications and Alerts
When connected to the phone, the band can show selected alerts. Notification access and the required background permissions must be enabled in the companion app for these features to work consistently.
- Incoming call vibration
- Message alerts
- Selected app notifications
- Alarm vibration
- Event reminders
- Idle alerts
If alerts are missing, first check the Bluetooth connection, notification permissions, background access, and Do Not Disturb settings.
Alarms
Alarms configured through the app can alert you with vibration on the wrist. They can be used for waking up, exercise reminders, daily routines, or personal medication reminders.
Because the alert is vibration-based, it can provide a quiet reminder without using a loud phone alarm.
Weather
When weather service is enabled and supported by the companion app, the band can display weather information such as current temperature, conditions, or forecast details.
Updated weather information depends on phone synchronization and may require location permission for the companion app.
More Menu
The More area contains extra tools and settings. The exact items can vary by firmware and configuration.
- Do Not Disturb
- Alarm
- Music control
- Timer
- Stopwatch
- Find device
- Silent mode
- Display settings
- Factory reset
Music Control
Supported configurations of the Mi Smart Band 4 can provide music playback controls while connected to the phone. Depending on the setup, controls may include play, pause, previous or next track, and volume adjustment.
Music control depends on an active phone connection, compatible media playback, and the companion app being allowed to operate as required in the background.
Using the Touch Button
The area below the display is touch-sensitive rather than a mechanical push button. Touch it gently to wake the screen. Inside many menus, touching it returns to the previous screen.
Basic Usage Illustration
The image below illustrates the basic usage and touch interaction of the Xiaomi Mi Smart Band 4, including screen activation and menu navigation.
Syncing With the App
Regular syncing transfers stored activity and health records to the companion app and keeps phone-managed settings aligned with the band.
- Step history
- Sleep records
- Heart rate history
- Workout records
- Battery information
- Settings changes
- Available firmware updates
If syncing becomes slow, keep the phone close to the band, reopen the companion app, or briefly toggle Bluetooth before trying again.
Battery and Charging
Battery use depends on how the band is configured. Display brightness, frequent heart rate monitoring, notifications, vibration alerts, workouts, and lift-to-wake can all affect how often charging is needed.
Battery-Saving Options
- Reduce display brightness when practical.
- Disable notifications you do not need.
- Reduce automatic heart rate monitoring frequency if that setting is available.
- Disable lift-to-wake if you do not use it.
- Use Do Not Disturb when appropriate, including at night.
- Sync regularly so stored records are transferred to the app.
Fit and Daily Wear
For everyday use, the band should be secure enough to keep the rear sensor in contact with your skin without feeling uncomfortably tight.
A loose band can move during walking, typing, sleeping, or exercise and may affect heart rate, sleep, and workout tracking. An overly tight strap can cause discomfort or leave pressure marks.
During Exercise
Arm movement and sweat can make the band shift. Tighten the strap slightly before exercise if needed to keep the sensor stable, then loosen it again afterward for normal comfort.
Cleaning and Care
Sweat, dust, soap, lotion, and moisture can collect on the strap, sensor, and charging contacts. Regular light cleaning helps maintain comfort and reliable contact.
[dosdonts] Do: Wipe the tracker with a soft, slightly damp cloth Do: Clean the strap after sweaty workouts Do: Dry the band before wearing it again Do: Keep the charging contacts clean and dry Dont: Use harsh chemicals on the tracker or strap Dont: Use abrasive cleaners that may damage the surface [/dosdonts]If wearing the band causes skin irritation, remove it for a while and clean both the strap and your wrist before wearing it again.
