Xiaomi Mi Smart Band 4 uses a color AMOLED touch display for time, activity data, notifications, workouts, weather, and media controls. Brightness, screen timeout, and wrist-wake behavior can be adjusted to balance visibility, comfort, and battery use.
Display at a glance
Most basic display controls are available directly on the band. Mi Fit is also used for settings such as raise-wrist behavior and band display styles.
Open display settings
Adjust brightness
Brightness has the biggest effect on how comfortable the display is in different lighting conditions. Higher levels improve visibility in bright environments, while lower levels are usually more comfortable indoors or at night.
[step] 1. Open Settings on the band. 2. Select Brightness. 3. Increase or decrease the level until the display is comfortable to read. 4. Return to the watch face when finished. [/step]The change applies immediately, so you can judge the result in the environment where you are using the band.
[compare] Indoors | Use low to medium brightness when the screen remains easy to read. Bright outdoors | Increase brightness only as much as needed for clear visibility. Dark rooms | Use a low brightness level to reduce glare when checking the band at night. Battery-focused use | Keep brightness at the lowest level that remains comfortable and readable. [/compare] [tip] If you raise brightness outdoors, reduce it again when you return indoors instead of leaving the display brighter than necessary. [/tip]Screen timeout
Screen timeout controls how long the display remains visible after it wakes. A short delay limits unnecessary screen-on time, while a longer delay gives you more time to read notifications or workout information.
[step] 1. Open Settings on the band. 2. Look for Screen timeout or the equivalent screen-off setting. 3. Select the available duration that gives you enough reading time. 4. Return to the previous screen when finished. [/step] [note] Custom screen timeout was added through Mi Smart Band 4 firmware updates. Available choices can therefore differ between firmware versions, and older software may provide fewer options. [/note]When the screen wakes, it turns off again after the configured period of inactivity. Using the display may keep it active while you navigate, although exact timing can vary by screen and firmware.
Choosing a timeout
- Quick glances: use a short timeout if you mainly check the time, steps, or another value briefly.
- Notifications: use a moderate timeout if you regularly need more time to read text.
- Workout information: choose enough time to read the metrics you use without keeping the display active longer than necessary.
Brightness and timeout work together. A bright display combined with frequent or long screen-on periods uses more battery than a dimmer display with a short timeout.
Wake the display
Xiaomi Mi Smart Band 4 can wake in more than one way.
[reference] Title: Touch Button Text: Tap the touch-sensitive button below the screen to wake the band. It is also used to return from menus. Title: Raise Wrist to View Text: When enabled, raising and turning your wrist toward you can wake the display automatically. Title: Notifications Text: Incoming alerts can light the display according to your notification and Do Not Disturb settings. [/reference]Set raise-wrist behavior
The raise-wrist feature is managed through Mi Fit. Depending on the app version, its wording may appear as Raise wrist to view info or similar.
[step] 1. Open Mi Fit. 2. Open Profile. 3. Select Mi Smart Band 4. 4. Find the raise-wrist or lift-wrist display setting. 5. Turn the feature on or off. 6. If scheduling is available, choose the period when wrist-wake should be active. [/step]Scheduling can be useful if arm movement wakes the display while you are sleeping. If you prefer fully manual control, disable wrist-wake and use the touch button when you want to check the screen.
[tip] A short screen timeout combined with raise-wrist wake provides quick access while limiting how long accidental wake-ups stay visible. [/tip]Night-friendly display setup
A softer display setup can make the band more comfortable in dark rooms and reduce unnecessary wake-ups during sleep.
[checklist] * Lower brightness before sleep if the normal level feels too strong in the dark * Keep screen timeout short * Use Do Not Disturb when you do not want alerts lighting or vibrating the band * Schedule or disable raise-wrist wake if nighttime movement activates the screen [/checklist]Do Not Disturb affects alert behavior rather than basic display brightness. It is useful when notifications are the main reason the screen keeps lighting at night.
Band displays and readability
The selected band display style also affects how easy the screen is to read. Layout, contrast, font size, and the amount of information shown can make a noticeable difference on the compact display.
- Contrast: light text on a dark background is usually easy to recognize at a glance.
- Font size: larger and thicker text can be easier to read outdoors or while moving.
- Information density: a simple display can make key values easier to find than a layout filled with many small items.
- Dark backgrounds: AMOLED displays can use less display power for dark areas than for large bright areas.
Change the band display style
[step] 1. Open Mi Fit. 2. Open Profile and select Mi Smart Band 4. 3. Open the band display settings. 4. Choose an available style. 5. Sync the selected style to the band. [/step]Some display styles emphasize the time, while others include information such as steps, date, heart rate, or battery level. Choose a layout that keeps the information you use most easy to identify.
Notifications and workouts
Notification display
When an enabled notification arrives, the band can wake and show an alert preview. The result depends on your notification, display, and Do Not Disturb settings.
- Brightness affects how strongly the alert appears.
- Screen timeout influences how long the display remains visible when there is no further interaction.
- You can navigate or dismiss the alert using the normal touch controls.
- Do Not Disturb can reduce unwanted notification wake-ups and vibration during selected periods.
Workout display
During supported workouts, the display can show live information such as elapsed time, distance, pace, or heart-rate data when available for that activity. Raising your wrist can provide quick access to the workout screen when wrist-wake is enabled.
Display timing can behave differently while a workout screen is active. For long sessions, use only as much brightness as needed to read your metrics comfortably.
Display and battery use
Display settings affect battery use because each wake-up activates the AMOLED screen. Frequent wrist-wake events, high brightness, long timeouts, and many notification wake-ups can all increase screen-on time.
[dosdonts] Do: Use low or moderate brightness when it remains readable Do: Choose a screen timeout that gives enough reading time without staying on unnecessarily Do: Limit raise-wrist wake if normal arm movement frequently activates the screen Do: Use Do Not Disturb or a wrist-wake schedule when you want fewer nighttime activations Dont: Leave maximum brightness enabled when it is not needed Dont: Use a longer timeout simply because it is available if a shorter setting is comfortable [/dosdonts]Display use is only one part of overall battery consumption. Notifications, workout tracking, heart-rate monitoring, and other active features can also affect how often the band needs charging.
Suggested display profiles
[compare] Indoor and office | Low to medium brightness, short timeout, wrist-wake optional, and a clear high-contrast band display. Outdoor and sports | Medium to high brightness as needed, moderate timeout for reading metrics, wrist-wake enabled, and a simple display with easy-to-read information. Battery saver | Lowest comfortable brightness, shortest useful timeout, wrist-wake disabled, and a simple mostly dark display style. Night use | Low brightness, short timeout, wrist-wake disabled or scheduled off, and Do Not Disturb enabled when appropriate. [/compare]These are starting points rather than fixed requirements. Adjust them around how often you check the band and the lighting where you normally use it.
Basic display checks
[troubleshoot] Problem: The display still looks dim at a high brightness setting Cause: The brightness level may not be at its highest setting, a screen film or cover may reduce visibility, or a display mode may be limiting brightness. Fix: Check the brightness setting, inspect any film or cover over the display, and restart the band if the appearance changes unexpectedly. Problem: The display feels too bright at night Cause: Daytime brightness may still be active, or alerts and wrist movement may be waking the display frequently. Fix: Lower brightness, use a shorter timeout, schedule or disable raise-wrist wake, and use Do Not Disturb when appropriate. Problem: The screen turns off before there is enough time to read it Cause: The selected timeout may be too short, or the current firmware may provide limited timeout choices. Fix: Open the screen timeout setting and choose a longer available duration. Continue interacting with the display while reading when needed. Problem: Raising the wrist does not wake the display Cause: Raise-wrist wake may be disabled, outside its scheduled period, or the wrist movement may be too subtle. Fix: Check the raise-wrist setting in Mi Fit, check its active schedule, and use a clear wrist-raise and turn motion. If the behavior changes unexpectedly, restart the band and reconnect or sync with Mi Fit. Problem: Touch input feels inconsistent Cause: Water, sweat, dirt, or wet fingers can interfere with touch input. Fix: Clean and dry the display and your hands. If touch behavior remains sluggish, restart the band from its available settings. [/troubleshoot]Quick setup balance
For everyday use, start with moderate brightness, a short or medium screen timeout, and raise-wrist wake enabled only during the hours when you normally check the band. Increase brightness temporarily for bright outdoor conditions, and reduce it again for indoor or nighttime use.
The most comfortable setup is the one that keeps the screen readable without causing unnecessary wake-ups or longer screen-on time.
