Xiaomi Mi Band 5 bracelet doesn’t connect to phone – what to do?

Xiaomi Mi Band 5 remains one of the most popular fitness trackers due to the balance of price and functionality, but even reliable devices have crashes. Most often, users experience a problem when the bracelet stops connecting to the phone - the indicator on the screen flashes, and the Mi Fit or Zepp Life application appears an error "Can not find the device" or "Connection is broken", the causes can be hidden in software failures and hardware malfunctions.

In this article, we will look at all possible scenarios, from commonplace errors (such as a Bluetooth disconnect or a dead battery) to complex cases where you need to reset your bracelet or reinstall your application. You will also learn how to distinguish a software failure from a communication module failure and when to contact the service center. All instructions are tested on current versions of the software (2026) and are suitable for Android and iOS smartphones.

1. Checking the basic connection conditions

Before you start complex manipulations, make sure that the minimum requirements for synchronization are met, and 60% of the time the problem is solved at this stage.

• 📱 Bluetooth is enabled on your smartphone (check notification panel or settings).
• 🔋 The bracelet is charged (minimum charge level for connection is 10%).The Mi Band 5 screen should display the battery indicator.
• 📲 App Updated: Use the latest Mi Fit (for old bracelet firmware) or Zepp Life (for newer ones).
• 📡 The distance between the devices does not exceed 10 meters (optimally up to 1 meter when you first connect).

Pay special attention to app permissions. On Android 10+ and iOS 14+, systems actively block access to geolocation and Bluetooth in the background. Go to your phone's settings, find the Mi Fit/Zepp Life app and turn on:

• 📍 Geodata (necessary for the correct operation of the pedometer and GPS).
• 🔄 Auto-run (so that the application does not close when folded).
• 🛡️ Ignoring battery optimization (on Xiaomi, Samsung, Huawei).

A critical feature of the Mi Band 5 is that the bracelet does not support simultaneous connection to multiple devices. If it was previously paired with another phone or tablet, first perform the decoupling in the application settings.

2.Reboot the bracelet and smartphone

The simplest but most effective method is to force both devices to restart, which clears the Bluetooth cache and resets temporary connection errors.

For the reboot of the Mi Band 5:

1. Connect the bracelet to the charger.
2. Press and hold the touch button under the screen for 10-15 seconds until the Mi logo appears.
3. Release the button and wait for the full load (about 30 seconds).

On your smartphone, a standard reboot is enough. If you use Android, go to Settings before rebooting → Applications → Mi Fit/Zepp Life → Memory → Clear the cache.

⚠️ Warning: If the bracelet shows endless loading after rebooting (the Mi logo does not disappear for more than a minute), this indicates damage to the firmware).

3. Update of the bracelet firmware and the application

Outdated software is a common cause of connectivity problems. Xiaomi regularly releases updates for the Mi Band 5 to fix Bluetooth connection errors.

1. Open the Mi Fit or Zepp Life app.
2. Go to the profile of the bracelet (stamp its icon on the home screen).
3. Select firmware update (if the item is missing, firmware is already relevant).
4. Confirm the boot and wait until the end (the bracelet will reboot automatically).

If the update is suspended during the Preparation for Update stage, follow the following steps:

• 🔌 Connect the bracelet to charging (update requires at least 50% charge).
• 📶 Connect your phone to Wi-Fi (mobile internet updates may be interrupted).
• ⏳ Do not interrupt the process – even if the indicator on the bracelet does not change for 5-10 minutes.

If the update doesn't start, try uninstalling and reinstalling the app. On Android, clear the app data in your phone's settings before you delete it. On iOS, standard deletion is enough and then reinstall from the App Store.

4. Reset bracelet settings to factory

If previous methods didn’t work, perform a hard reset of the bracelet, which will remove all data from the device (steps, pulse, settings), but often solves connection problems.

Instructions for Mi Band 5:

1. Open the menu on the bracelet by swiping up the screen.
2. Go to Settings → More → Reset (icon with wrench).
3. Confirm the action by tapping the tick.
4. Wait for the reboot (the bracelet vibrates and shows the Mi logo).

After discharge:

• 🔄 Reboot your smartphone.
• 📱 Remove the bracelet from the list of Bluetooth devices in your phone settings.
• 🔗 Launch the application and re-attach.

⚠️ Note: Some Mi Band 5 firmware may require re-activation via reset QR-If the app asks you to scan the code from the bracelet screen, but it doesn't appear, reboot the bracelet again.

5. Bluetooth problems: Diagnostics and solutions

If the bracelet is not detected by the phone at all (not displayed in the list of available devices), the problem may lie in the Bluetooth module of the smartphone or bracelet.

Step 1: Checking Bluetooth on your phone

• 📱 Test with another device: try connecting your phone with headphones or other headset. If they don't, you'll see a malfunction in your smartphone module.
• 🔄 Reset network settings (on Android): Settings → System system → Reset → Reset Wi-Fi, mobile network and Bluetooth.
• 🛠️ Update drivers (for Windows when connecting through Android emulators).

Step 2: Checking the bracelet

• 🔍 Visual inspection: On the back of the body of the Mi Band 5 is a Bluetooth chip (near the pulse sensor.
• 🔋 Test with another phone: try connecting the bracelet to a friend's device. If it doesn't, a malfunction in the bracelet.
• 📡 Signal check: Hold the bracelet close to the phone (1-2 cm) If the connection appears only at this distance, the antenna of the bracelet is damaged.

On Android, you can use a Bluetooth Scanner app (like nRF Connect) to check the bracelet signal, and if the device doesn't show up in the scanner, it's a hardware problem.

💡

If you have a Xiaomi/Redmi smartphone, turn on the developer mode and activate the Bluetooth debugging option in the settings, which will help diagnose connection errors through logs.

6 Conflicts with other devices and applications

Mi Band 5 can conflict with other gadgets or programs that use Bluetooth.

• 🎧 Other Bluetooth devices: If you have a headphone, speaker or car system connected to your phone, they can block the connection to the bracelet.
• 📱 Duplicate apps: If both Mi Fit and Zepp Life are installed on your phone, remove one of them).
• 🛡️ Antivirus and VPN: Programs like Avast, Kaspersky, or NordVPN can block Bluetooth access.
• 🤖 Battery optimizers: on Xiaomi/Redmi/Samsung Apps like Security or Device Care aggressively shut down background processes. Add Mi Fit to exceptions.

If you use custom firmware (like LineageOS or Pixel Experience), the problem may be that the Bluetooth stack is not working properly.

• 🔄 Refuse the Bluetooth module through TWRP (Find the right.zip for your phone model).
• 📱 Install official firmware (if the bracelet is critically important).

7. When to contact the service center

If none of the methods worked, but the bracelet:

• 🚫 It does not turn on even after charging.
• 📡 Not detectable by any device.
• 🔥 It overheats or gives off an unpleasant smell.
• 💧 Was exposed to moisture (despite the claimed water resistance, salt or chlorinated water can damage the contacts).

These are signs of hardware failure, and in these cases, professional diagnostics are required.

Official Xiaomi service centers in Russia and CIS provide warranty repairs in the presence of a check.

Before the service visit:

• 📄 Keep a check or a warranty card (if you bought the bracelet less than a year ago).
• 🔋 Charge the bracelet to 100% – this will speed up the diagnosis.
• 📱 Remove the bracelet from the application so as not to block the binding to the test device of the wizard.

💡

If the bracelet is warranty, DO NOT open it yourself - this will void the warranty.
