How to connect Xiaomi Mi Smart Band 4C to your phone: full instructions with pictures and tips

Fitness bracelet Xiaomi Mi Smart Band 4C — One of the most popular activity trackers, thanks to the combination of affordable prices and extensive functionality, but many users have difficulty connecting the device to a smartphone first. 4C-The version has its own synchronization features, which are often overlooked even in official instructions.

In this article, we will look at the step-by-step process of connecting the Mi Band 4C to Android and iOS phones, look at common errors (for example, when the bracelet is not detected or permanently disabled), and give recommendations for optimizing the device after the first setup.

If you've just unpacked the bracelet and you see --:- or the Pair on the screen, don't panic -- that's normal until the first synchronization. The rule is, don't try to plug the bracelet into the phone's Bluetooth menu manually. That will cause the pairing protocol to fail, and the device will have to reset. All manipulations must go through the official app.

The time it takes to connect is usually 5-7 minutes, but can increase if you have an outdated version of the software on your smartphone or bracelet. Mi Band 4C requires a minimum version of Android 5.0 or iOS 10.0 - if your phone is older, sync will not be possible.

1.Preparation for connection: what to do before installing the application

Before you download Mi Fitness and try to connect devices, follow a few preliminary steps that will save you 90% of the typical problems that users face.

First, check the bracelet's charge. The Mi Band 4C comes with a partially charged battery, but if the display on the screen shows less than 20%, plug the device into charging for 30-40 minutes. Charging should come from the original cable (or certified counterpart) - using uncertified adapters can cause firmware to fail.

Second, make sure that on your smartphone:

• 📱 Bluetooth enabled (no Visible for All mode required).
• 🌐 Active Internet connection (Wi-Fi or mobile data) The application will need to download firmware updates for the bracelet.
• 🔒 Geolocation permits (required for the pedometer to operate properly and GPS-tracking).
• 📲 Free space of at least 200 MB (appendix) + update cache).

If you have previously used another Xiaomi fitness bracelet (such as Mi Band 3 or 4), remove it from the list of associated devices in the Bluetooth settings. Profile conflict can interfere with the correct 4C connection.

⚠️ Note: On phones with custom firmware (for example, LineageOS or MIUI Global with modifications may not work automatic detection of the bracelet. In this case, try manually select the model Mi Smart Band 4C in the list of devices when added.

2. Installation and configuration of the Mi Fitness application

The official Mi Band 4C management app is Mi Fitness (formerly Mi Fit).

Important: Do not use third-party APKs (such as those from sites like APKMirror) unless you want to experience sync errors or data leaks. Also check that you have the latest version of the app - older releases may not have 4C support.

After installation, follow the following steps:

1. Open Mi Fitness and select the region of Russia (or your country).
2. Accept the terms of use and allow access to notifications, contacts and geolocation.
3. Click Add Device → Bracelet → Mi Smart Band 4C
4. Follow the instructions on the screen when the app asks you to bring the bracelet to your phone.

If you fail to connect at this stage, try:

• 🔄 Reboot Bluetooth on your phone (turn off/on).
• 📱 Remove the Mi Fitness app cache in your phone settings.
• 🔋 Remove the bracelet from the charger (if it was connected) and try again.

3. Synchronizing the bracelet with the phone: a step-by-step process

When the app finds the Mi Band 4C, the phone will have a pairing request on its screen. Don't confirm the connection in the Bluetooth system window, wait for Mi Fitness to initialize the process itself. If you click "Plug" in the system settings, the bracelet may be defined as "unknown device" and stop responding to commands.

Follow the algorithm further:

1. The bracelet will appear 4-digit code - enter it in the application.
2. Confirm the pairing on the phone and on the bracelet (click on its screen tick).
3. Wait for the firmware update to complete (it can take up to 10 minutes) and don't interrupt the process even if the bracelet reboots.
4. Set up the basic parameters: 🕒 Time zone (must coincide with the phone). 🏃 Sex and Date of Birth (for calorie counting). 📏 Units of measurement (metres/kilometers or feet/miles).

After successful synchronization, the current time will appear on the bracelet screen, and the basic data (steps, pulse, charge level) will appear in the application. If the time on the bracelet is not updated, check the synchronization settings in Profile → Mi Smart Band 4C → Autosynchronization.

2. Turn on the Application Notification switch.
3. Select the apps you want to see on your bracelet (for example, WhatsApp, Telegram, VK).
4. Set up the vibrating style and display text (full text or sender name only).

6.Resetting the Mi Band 4C settings to factory

If the bracelet is unstable or you want to transfer it to another user, perform a hard reset, which will delete all data from the device, including Bluetooth pairs and notification settings.

Method 1 (through bracelet):

1. On the main screen of the bracelet, swipe right to the Settings menu (cog icon).
2. Select Reset → Confirm.
3. Wait for the reboot (the bracelet vibrates and shows the Mi logo).

Method 2 (if the bracelet does not respond):

2. Press and hold the touch button for 10-15 seconds until you feel the vibration.
3. Release the button - the bracelet will reboot in factory condition.

After resetting, the bracelet will appear in Mi Fitness as a new device and you will need to reconnect (see Section 3).

💡

If you reset the bracelet before selling, be sure to untie it from your Xiaomi account in the app settings.This will protect your data and allow the new owner to connect the device without any problems.

7. Optimization of the bracelet after connection

To ensure that the Mi Band 4C is stable and cost-effective, follow these tips:

• 🔋 Turn off unnecessary notifications – every alert consumes ~1% charge.
• 🌙 Activate the "Do Not Disturb" mode at night (Settings) → Don't disturb).
• 📊 Manually synchronize data 1-2 times a day (autosynchronization consumes battery).
• 💡 Reduce the brightness of the screen to 2-3 divisions (in bracelet settings).

We also recommend updating the bracelet firmware to the latest version.

1. Open Mi Fitness. → Profile → Mi Smart Band 4C.
2. Click the Software Update (if available).
3. Confirm the load and wait until the bracelet is completed (rebooted).

The average lifetime of the Mi Band 4C on a single charge is 10 to 14 days at standard settings. If the battery is going down faster, check:

• 📲 Data synchronization frequency (optimally - 1 time in 6 hours).
• 🏃 Use of the GPS (Turn off if you don’t need to track the routes).
• 🔍 Background processes Mi Fitness (on Android check in Settings) → Annexes).

💡

Regularly update the firmware of the bracelet – new versions fix synchronization errors and add new features (for example, support for additional types of workouts).
