Did you pull out of the box a new (or long-standing) fitness bracelet Xiaomi Mi Band 5, but he stubbornly refuses to connect to the smartphone? Or the device suddenly fell off the application Mi Fitness after the update? The problem is familiar to many owners — according to service centers, 38% of calls on the Mi Band 5 are due to pairing errors, the causes can be hidden in software failures and hardware malfunctions.
In this article, we'll look at all possible scenarios, from a simple battery discharge to firmware conflicts, how to diagnose a problem by the error code (if it appears in the app), what phone settings block the connection, and what to do if the bracelet is determined by the system but not synchronized. And for the most difficult cases, we've prepared instructions for forced resetting and flashing the device -- with step-by-step screenshots and commands for ADB.
Important: If your Mi Band 5 was previously working normally and now doesn't connect after a fall, impact or moisture, go straight to the hardware malfunction section.
1. Basic checks before setting up
Before digging deep into the settings, make sure the problem isn't in the rudimentary things.In our experience, 4 out of 10 Mi Band 5 malfunctions are resolved at this stage.
- 🔋 Charging the bracelet: Connect the device to the charging cable (original!) and wait 10-15 minutes. Even if the indicator doesn't burn, try holding it longer - sometimes the contacts oxidize. Minimum charge level for pairing: 20%.
- 📱 Phone Compatibility: Mi Band 5 Officially Supports Android 5.0+ iOS 10.0+. On older versions, the Mi Fitness app may not install or malfunction.
- 📶 Bluetooth and location: Turn on Bluetooth on your phone and allow the app to use geodata (required to find devices). on Android 12+ Also check the permission for the exact location.
- 🔄 Reboot devices: Turn off and turn on the bracelet (hold the touch button for 10 seconds), then restart the phone.
If you still don't know the bracelet after this manipulation, move on to the next section, and if you see the Mi Band 5 on the list of available devices, but the connection breaks down, the problem is more of a software conflict (more on this below).
2. Set up the Mi Fitness app
Mi Fitness (formerly Mi Fit) is a key intermediary between the wristband and the phone, and errors are the second most common cause of connectivity problems.
Scenario 1: The app does not see the bracelet
- 📥 Update Mi Fitness: Go to Google Play or App Store and check the version's relevance.Old versions may not support Mi Band 5 protocols.
- 🗑️ Clear the cache: On Android go to Settings → Annexes → Mi Fitness → Memory. → Clear the cache. On iOS, delete and reinstall the app.
- 🌍 Change region: In the application settings (Profile) → Region: Select China or Singapore – sometimes this solves Xiaomi server problems.
Scenario 2: Connection breaks down during synchronization
If the bracelet appears in the list of devices, but when pairing attempts, it gives an error (for example, failed to connect or Error 1006), follow the following steps:
Remove the bracelet from the list of devices in Mi Fitness|
Turn off Bluetooth on your phone for 30 seconds |
Turn on the plane mode for 10 seconds, then turn off |
Try to connect again.-->
If nothing works, move on to reset the bracelet, but before you do, check if your phone is blocking the connection.
💡
On some Xiaomi firmware (e.g. MIUI 13), the built-in Bluetooth Security feature can block fitness bracelets from connecting. Disable it in Settings → Connections → Bluetooth → Settings (cogs) → Bluetooth Security.
3. Phone settings blocking the connection
Modern smartphones aggressively optimize energy consumption and security, which sometimes interferes with the work of accessories.
| Problem. | Where to find | How to fix it |
|---|---|---|
| Bluetooth shuts down in the background | Settings → Battery → Battery Optimization | Add Mi Fitness to the exceptions |
| Limitations for background processes | Settings → Applications → Mi Fitness → Battery | Choose Without Limitations |
| Blocking location authorization | Settings → Privacy → Permits → Location | Always allow for Mi Fitness. |
| Conflict with VPN or firewall | Settings → VPN or Security → Firewall | Disable VPN during pairing |
On the iPhone, check out:
- 🔄 Resetting network settings: Settings → Mainstream → Transfer/Dumping → Network resets. This will delete all stored Wi-Fi and Bluetooth devices, but often helps.
- 📱 iOS Update: On versions below iOS 14, there may be problems with Bluetooth 5.0, which uses Mi Band 5.
⚠️ Note: If you use Custom ROM (For example, LineageOS, the problem may be that the Bluetooth stack is not implemented correctly.
4. Resetting the bracelet to factory settings
If all previous methods have failed, it’s time to reset the Mi Band 5 to factory status, which will remove all data from the device (steps, alarm clock settings, etc.), but often resolves connection issues.
Method 1: Through the menu of the bracelet
- On the bracelet, swipe up from the main screen to open the menu.
- Find the Settings (cog icon) → Additional → Reset.
- Confirm the action by clicking the tick. The bracelet will reset.
Method 2: Forced reset (if menu is not available)
- Turn off the bracelet from charging.
- Hold the touch button for 20 seconds until you feel the vibration and see the Mi logo.
- After rebooting, try connecting again.
If the reset didn't work, maybe the problem is the bracelet's firmware, and that's in the next section.
💡
Resetting the bracelet deletes all data, including activity history. If you have important data, try first synchronizing it through another device (for example, a tablet).
5. Updating or flashing the bracelet
Outdated or damaged firmware can cause connectivity problems. Xiaomi regularly releases updates for the Mi Band 5, but sometimes they get stuck in the installation process.
Step 1: Check the current version of the firmware
In the Mi Fitness app, go to Profile → Mi Smart Band 5 → Update firmware. If a new version is available, upgrade. If the update is 0% or 50% hanging, follow the steps below.
Step 2: Forced renewal through ADB
For power users: If the standard update doesn’t work, you can manually flash the bracelet through ADB.
- 🖥️ Computer with installed ADB and Xiaomi drivers.
- 📁 Firmware file for Mi Band 5 (download from the official website or forum) XDA Developers).
- 🔌 Cable to connect the bracelet to the PC (needs special adapter or soldering skills).
Commands for firmware (execute in the command line):
adb devices
adb shell am start -n com.xiaomi.hm.health/com.xiaomi.hm.health.upgrade.UpgradeActivity⚠️ Warning: The wrong firmware can permanently incapacitate the bracelet. If you are not sure of your skills, contact the service center. Also make sure that the firmware file matches the region of your bracelet (for example, if you are not sure of your skills, contact the service center, CN For China, Global for International Version).
What to do if the firmware has completely gone off?
Hardware malfunctions and repairs
If none of the software methods worked, the problem may be a physical malfunction of the bracelet, and here are the typical symptoms and their causes:
| Symptoms. | Possible cause | Decision |
|---|---|---|
| The bracelet does not charge, does not respond to touch. | Battery or power controller damaged | Replacement of the battery in the service center |
| It's plugged in, but it's shut down. | Oxidation of Bluetooth module contacts | Cleaning with alcohol or replacing the module |
| Vibration works, but the screen is not turned on | The display plume has detached. | Disassembly and rationing of the plume |
| The bracelet warms up when charging | Short circuit in the food chain | Diagnosis with a multimeter, replacement of elements |
If the bracelet fell, got wet or was subjected to mechanical stress, examine it for:
- 💧 Corrosion traces on charging contacts (green plaque).
- 🔧 Cracks on the body, especially near the button.
- 🔋 Battery bloating (seen if you slightly bend the body).
You can use a resistance tester (multimeter) to test the circuit between the charging contacts. Normal resistance: 5-10 kOhms. If the readings are very different, this is a sign of malfunction.
Cost of repairs in service centers:
- Battery replacement: 800–1500 ₽.
- Display replacement: 1200–2000 ₽.
- Repair of Bluetooth module: 1500-2500 ₽.
⚠️ Warning: If the bracelet is wet, don't plug it into charging, it may cause a short circuit. Place the device in rice or silica gel for 24 to 48 hours before any manipulation.
