How to turn on and configure Xiaomi Mi Smart Band 4: instructions for beginners

Xiaomi Mi Smart Band 4 is one of the most popular fitness trackers on the market, combining affordable price, stylish design and wide functionality. However, even with such a simple device, users often have questions: how to turn it on correctly, what to do if the bracelet does not respond to presses, and how to avoid typical errors when you first set up.

Contrast AMOLED-The screen, call notifications, sleep monitoring, and 20 training modes make the Mi Band 4 a versatile assistant, but for all of these features to work, you need to activate the device correctly. We will take a detailed look at each step, from unpacking to the first steps in the app, and also tell you what to do if something goes wrong.

Preparation of the bracelet for the first inclusion

Before you turn on the Mi Smart Band 4, make sure the device is fully charged. It comes with a special charging cable with magnetic contacts. USB-port (computer, charger or power bank) and place the bracelet so that the contacts on the back side coincide with the cable connector.

It takes about 1.5 to 2 hours to fully charge, and the green light on the cable signals the end of the process. If the light is not on, check the density of the contacts or try another one. USB-The bracelet doesn't turn on when the battery is empty - that's okay, don't panic!

• 🔋 Use only the original cable from the kit – third-party chargers can damage the battery.
• ⚡ Do not leave the bracelet on charge for more than 3 hours – this reduces the battery life.
• 📱 Prepare a smartphone with the Mi Fit app installed (available for Android and iOS).

If the bracelet does not start charging, check:

1. Cleanliness of contacts on the bracelet and cable (wipe them with a dry napkin).
2. Correction USB-Port (try charging another device).
3. Integrity of the cable (whether there is damage to the insulation or contacts)

2. How to physically turn on the bracelet: button and sensor

After charging, you can start to turn on. The Mi Band 4 does not have a traditional power button, but is controlled through the touch screen and a single physical touchpad under the display.

1. Click on the touchpad (the sensitive area under the screen) and hold for 3-5 seconds.
2. Wait for the Mi logo to appear on the screen – this is a signal to start downloading.
3. After downloading, you will see the main menu with time (if the bracelet has already been paired) or the welcome screen (if it is the first inclusion).

If the bracelet does not respond to touchpad retention:

• 🔄 Try to briefly press the touchpad 2-3 times in a row - sometimes it "wakes up" the device.
• 🔋 Make sure the charging is actually complete (the indicator on the cable is out).
• 🔌 Connect the bracelet to charge for 10-15 minutes, then try again.

⚠️ Note: If the bracelet does not turn on even after a long charge, there may have been a reset).

On the welcome screen, you will see animations asking you to connect to the Mi Fit app. This is normal – the bracelet is ready to pair, but without a smartphone, its capabilities will be limited (for example, there will be no exact time and notifications).

3. Installation and configuration of the Mi Fit application

Mi Fit is a must-have for the full-fledged Mi Smart Band 4, available for Android 5.0+ and iOS 10.0+. Download it from official stores:

4.Pairing the bracelet with a smartphone

The pairing process is usually automatic, but sometimes requires manual intervention.

1. Click "Connect" in the app.
2. On the bracelet will be a request for confirmation - briefly click on the touchpad.
3. Wait until the synchronization is complete (it can take up to 1 minute).

• 🔄 Reset the bracelet (hold the touchpad for 10 seconds until vibration).
• 📱 In the Bluetooth settings of the smartphone find the device «MI Band 4" and remove it, then re-pair it.
• 🔌 Try connecting from another phone – this will help to identify the problem (in the bracelet or smartphone).

• 🕒 The bracelet will automatically set the exact time (synchronized with the phone).
• 🔔 Notifications of missed calls and messages will appear (if you have been allowed access).
• 📊 The Mi Fit app will display data on steps, pulse and charge level.

⚠️ Note: If the bracelet displays the wrong time after pairing, check the time zone settings on your smartphone. The bracelet takes time from there, not from the Internet.

5. Forced reset and reset settings

Sometimes the bracelet can freeze, not respond to pressing, not turn on or show synchronization errors, in which case a forced reboot helps:

1. Connect the bracelet to the charger.
2. Hold the touchpad for 15-20 seconds until you feel the vibration.
3. Release the button and the bracelet will reboot (the Mi logo will appear).

If the reboot didn’t help, reset to factory settings:

1. In the Mi Fit app, go to Profile → Mi Smart Band 4 → Untie the device.
2. On the bracelet, hold the touchpad for 10 seconds until vibration, then confirm the reset (if a request appears).

After the reset, all data on the bracelet will be deleted, but the information in Mi Fit will remain (if it was synchronized).

After pairing, configure the main parameters in the Mi Fit application:

1. User Profile: Specify gender, age, weight and height for accurate calorie and step counts.

• A short touchpad is a step back.
• Fingerwire up/down - scroll the menu.
• Fingerwire left/right – switching between screens (time, steps, pulse).

If you’re missing features, check the settings in Mi Fit – some options (like sleep monitoring) are only activated via the app.

7. Frequent errors and their solutions

Even after successful activation, users face typical problems, and here are the most common ways to fix them:

• 🚫 The bracelet does not vibrate at notifications: Check the notification settings in Mi Fit (Notifications section). Make sure your smartphone allows access to alerts for Mi Fit. Reset the bracelet.
• 🔋 Battery goes down fast: Turn off constant pulse monitoring (in bracelet settings). Reduce screen brightness. Update firmware through Mi Fit.
• 📵 Bracelet disconnects from phone: Make sure the distance between devices is less than 10 meters. Check if Bluetooth is blocking another application (e.g. battery saver). Reconnect the bracelet to Mi Fit.

⚠️ Warning: If the bracelet has stopped syncing your steps or sleep data, try removing it from Mi Fit and adding it again.

If none of these methods worked, check the bracelet on another smartphone to help you determine whether it’s in the tracker itself or in your phone.
