Synchronizing Xiaomi phone with fitness bracelet: full instruction from connection to error elimination

Xiaomi fitness bracelets (Mi Band, Smart Band Pro and others) have long been an integral part of the brand ecosystem, but their full operation is impossible without proper synchronization with a smartphone. Even experienced users sometimes face problems: the bracelet does not connect to the phone, data does not update, notifications come with a delay or disappear altogether. In this article, we will analyze all the steps of synchronization – from the first connection to fine-tuning notifications and solving typical errors.

Xiaomi devices require not only a physical Bluetooth connection, but also the right setup in the Mi Fitness app (formerly Mi Fit), which can vary depending on the bracelet model (for example, the Mi Band 7 Pro supports GPS, while the Mi Band 6 does not) and the firmware version of the phone. We took into account all the nuances to make the instruction suitable for most current devices.

If you've just purchased a bracelet or experienced problems after a software update, this article will help you figure it out. We've also added a bracelet/smartphone compatibility table, a checklist for troubleshooting, and answers to frequent questions. Let's start with a basic setup.

Preparation for synchronization: what to do before connecting

Before you start syncing, make sure your smartphone and bracelet are ready to go, and skipping these steps often leads to errors like “Device Cannot Be Found” or “Sync is interrupted.”

First, check the operating system version on your phone. Xiaomi bracelets officially support Android 6.0+ and iOS 10.0+, but Android 8.0 or later is recommended for stable operation. You can find out the version from the Settings → About Phone menu. If your smartphone is outdated, some features (such as fast sync or notifications) may not work properly.

Second, update the firmware of the bracelet, and even if it's new, it can have a factory version of the bug software, and it solves most of the connectivity problems.

• 🔋 Charge the bracelet to at least 50% (upgrade consumes a lot of energy).
• 📱 Install Mi Fitness from Google Play or App Store.
• 🔄 Turn on Bluetooth and GeoData on your phone – without them, the app will not be able to find the bracelet.

If you have a Mi Band 7 Pro bracelet or newer, also make sure your phone is Wi-Fi enabled - some features (like weather download or firmware update) require an internet connection. For Mi Band 5 and older models, this is not necessary, but is recommended.

2. Step-by-step instructions: how to connect the bracelet to the phone

Now, to the synchronization process itself, we're going to look at two scenarios: first connection (when the bracelet is new) and reconnection (for example, after resetting). The algorithm is slightly different.

First connection (new bracelet)

1. Activate the bracelet. Press the touch button (or screen if it's a display model) to turn on the device. QR-code".
2. Launch Mi Fitness. When you first open, the app will prompt you to sign up or sign in through your Xiaomi account. Use the same account as your phone (if it’s tied to the Xiaomi ecosystem).
3. Add the device. Click Profile → Add device and select the model of your bracelet from the list. If there is no model, select Other device and enter the name manually.
4. Scanner. QR-Point the phone camera at the QR-If the code is not read, enter the 6-digit PIN, bracelet.
5. Confirm your connection. Your phone and bracelet will be notified of successful synchronization. Click "Done" in the app.

Reconnection (after reset or error)

If the bracelet has already been connected before, but the sync is gone (for example, after updating the phone), follow the following steps:

1. Open Mi Fitness and go to Profile → My Devices.
2. Find your bracelet in the list and click on it. Select "Disable" (or "Delete Device").
3. Return to the main menu of the application and click "Add device" again.
4. Follow the instructions as you did when you first connected (QR-code PIN).

If the bracelet is not detected, try restarting it.

• 🔄 On models with a button: hold it for 10-15 seconds until vibrations appear.
• 📱 On touch screen models: swipe down from the top edge and select Reboot".

3. Notification setting and data synchronization

Once you've successfully connected, you need to configure what data will be synchronized between the wristband and the phone, and what notifications will arrive on the device's screen, which is done in the wristband menu in the Mi Fitness app.

Go to Profile → Your Device → Notifications. Here you can:

• 📩 Enable/disable call notifications (the bracelet will vibrate when incoming call).
• 📱 Allow notifications from specific applications (e.g. WhatsApp, Telegram, Gmail).
• 🔕 Set up a “Do Not Disturb” mode on a schedule (for example, during sleep).
• 🔔 Select the vibration style (short/long) and repeat notifications.

To synchronize your health data (steps, pulse, sleep), go to Profile → Your Device → Data Synchronization and enable options:

• 👟 Steps and activity (automatic synchronization every 30 minutes).
• ❤️ Heart rate (measured every 5–30 minutes, depending on the model).
• 😴 Sleep monitoring (automatic phase detection of sleep).
• 💦 Stress level (available on Mi Band) 7/8 Smart Band Pro).

Important: If you use multiple health apps (like Google Fit or Apple Health), Mi Fitness should allow you to share data with them. Go to Profile → Settings → Connected Apps and activate sync.

💡

If notifications come with a delay, try turning off the power saving mode for the Mi Fitness app in your phone settings. On Xiaomi, this is done in the Settings menu → Battery → Application Selection → Mi Fitness → Without restrictions

4. Solving synchronization problems

Even when you set it up properly, the bracelet can stop syncing, and let's look at some of the most common mistakes and how to fix them.

If none of these things worked, try resetting the bracelet to the factory.

1. Open Mi Fitness and go to your device’s menu.
2. Select "Additional settings → Reset to factory."
3. Confirm the action and wait for the bracelet to restart (it will take 1-2 minutes).
4. Reconnect the bracelet as you did when you first used it.

Warning: Reset will delete all data from the bracelet (steps, sleep history, etc.), but it will be saved to the Mi Fitness account if sync has been enabled.

5. Updating the firmware of the bracelet via the phone

Regular firmware updates fix bugs, add new features and improve stability. You can check for updates in the Mi Fitness app:

1. Open the Profile tab and select your bracelet.
2. Go to firmware update.
3. If a new version is available, click "Update".
4. Wait until the process is complete (the bracelet will reboot automatically).

Important nuances:

• 🔋 Make sure the bracelet is at least 60% charged – if charging is interrupted during the upgrade, the device may fail.
• 📶 Connect your phone to stable Wi-Fi – upgrade via mobile internet may interrupt.
• ⏳ If the update is stalled, wait 10-15 minutes. If nothing happens, restart the bracelet and try again.

On some models (e.g. Mi Band 7 Pro), the upgrade can take up to 20 minutes. Don't worry if the bracelet screen goes out - that's normal.

💡

Updating the firmware through Mi Fitness is the only official way. Do not use third-party firmware, it can lead to loss of warranty and unstable bracelet performance.

6. Sync with other Xiaomi devices

If you have other Xiaomi gadgets (such as smartwatches, headphones or speakers), the bracelet can be integrated into a single ecosystem.

1. Make sure that all devices are linked to one Xiaomi account.
2. Open the Mi Home app (if installed) and check that the bracelet appears in the list of devices.
3. In Mi Fitness, allow data sharing with other gadgets (“Profile → Settings → Xiaomi Ecosystem”).

For example, if you have a Xiaomi smart alarm clock, the bracelet can automatically transmit sleep phase data to make the alarm go off at the optimal time, and if you use Xiaomi headphones, the bracelet can show their charge level.

For owners of Xiaomi smartphones (Redmi, POCO, Mi series) additional features are available:

• 🔓 Unlocking the phone on the bracelet (setting in Settings) → Lock screen → Unlocking with the Mi Band device).
• 📷 Removed image – the bracelet can serve as a shutter button for the phone’s camera.
• 🎵 Music management – switching tracks directly from the bracelet screen.

These features only work on smartphones with MIUI 12 shells and later. If you have other firmware (like Global ROM or custom), some options may not be available.

7 Energy saving: how to extend the life of the bracelet

One of the main questions users have to ask is how to reduce battery consumption without losing functionality. By default, the device constantly synchronizes data, measures pulse and monitors activity, which drains the battery in 5-7 days.

Optimization of settings:

• ❤️ Reduce your pulse rate to 1 time every 30 minutes (instead of 5 minutes).
• 🌙 Turn off automatic sleep monitoring if you are not using this feature.
• 📶 Turn off a permanent Bluetooth connection (in bracelet settings, select "Connect only for synchronization").
• 🔦 Reduce screen brightness and backlight time (e.g. up to 5 seconds).

Additional advice:

• 🔋 Use only the original charging cable – cheap analogues can damage the battery.
• 🚫 Do not leave the bracelet on charge for more than 2 hours – this reduces the battery life.
• 📴 Reload the bracelet once a week (hold the 10 seconds button) – this resets the background processes that consume energy.

The Mi Band 8 and Smart Band Pro also have Power Saving mode, which turns off all functions except time display, and it is included in the bracelet menu: Settings → Battery → Power Saving Mode.

💡

With the right settings, the Mi Band 7 bracelet can last up to 15 days on a single charge, and the Smart Band Pro can last up to 14 days (taking into account the use of GPS).
