Xiaomi Mi Band 5 doesn’t connect to phone: a complete troubleshooting guide

Why does Mi Band 5 refuse to connect to a smartphone?

Xiaomi Mi Band 5 fitness bracelet is one of the most popular wearables due to its combination of price and functionality. But even proven gadgets crash, and the problem with connecting to the phone is most common. Are you trying to synchronize data, and the bracelet is persistently not determined in the Mi Fit or Zepp Life app? Or the connection is constantly broken after a few seconds?

There are many reasons, from the banal discharge of the battery to the software conflicts between the firmware of the bracelet and the version of the application. In this article, we will analyze all possible scenarios, including the rare cases when the bracelet is not the fault, but the settings of the phone or even the operating system. It is important to understand that the algorithm of the decision depends on the stage at which the failure occurs: the bracelet is not visible in the list of devices, connects but immediately turns off, or sync is suspended at 0%.

Before you go to radical measures (like resetting the bracelet to factory settings), check the basic parameters: battery power, Bluetooth enabled, no interference from other devices. Sometimes the problem is solved in literally 30 seconds - just reboot both the phone and the bracelet.

If standard methods don't work, don't rush to the service center, 90 percent of the time, the malfunction is software, and you can fix it yourself, and then you can take the step-by-step instructions for each of the possible causes.

1. Checking the basic connection conditions

Start with the obvious, users often miss the basics that make the bracelet unable to connect.

Charge Mi Band 5 to at least 20% | Turn on Bluetooth on your phone | Make sure the bracelet is near your phone (no further than 1 meter) | Close all background applications that use Bluetooth (earphones, speakers, etc.)

-->

Pay special attention to the charge level. If the bracelet battery is discharged to 5% or below, it can turn on, but will not appear in the list of available devices. Connect the Mi Band 5 to charge for 10-15 minutes, even if the indicator shows residual charge.

Also check if other Bluetooth devices are connected to your phone, for example, if you're trying to sync your bracelet and wireless headphones at the same time, you may have a channel conflict.

⚠️ Note: On iPhone (iOS) after upgrading to version 17+ Sometimes you reset permissions for applications. Go to Settings. → Confidentiality → Bluetooth and make sure that Mi Fit or Zepp Life has access to the connection.

2.Reboot the bracelet and smartphone

The classic off-and-off method works with wearables, starting with the Mi Band 5 reboot:

Remove the bracelet from your hand and place it on a flat surface.
Find on the bracelet screen the Settings item (cog icon).
Scroll down to the Reboot (or Reboot) option and confirm the selection.
If the screen is not responding, perform a forced reboot: connect the bracelet to charging and hold the touch button for 10-15 seconds until the Mi logo appears.

When you reboot the bracelet, make sure you restart your smartphone. On Android, hold the power button and select "Reboot." On your iPhone:

❄️ For models with Face. ID: Press and hold the side button and one of the volume buttons at the same time until the turn off slider appears.
🔘 For the iPhone. SE (2nd generation) or older: hold the side button.

After the double reboot, try reconnecting. If the problem persists, move on to the next step.

💡

If the bracelet does not respond to touch, check if moisture or sweat has fallen under the screen. Rub the surface with a dry wipe and let the device dry for 10-15 minutes.

3. Update of the application and firmware of the bracelet

An outdated version of Mi Fit or Zepp Life is one of the most common causes of connectivity problems. Developers regularly release patches to fix synchronization errors, so check the relevance of the software:

📱 On Android: Open the Google Play Store, find Mi Fit or Zepp Life and update if a new version is available.
🍎 On iOS: go to the App Store, go to the “Updates” section and check for updates for the app.

If the app is updated, but the bracelet still does not connect, check the firmware version of the Mi Band 5 itself:

Open the Mi Fit/Zepp Life app.
Go to the bracelet profile (usually the device icon at the top of the screen).
Select the Firmware Update (or Firmware Update).
If a new version is available, plug the bracelet into charging (the battery must be at least 50% charged) and wait until the process is complete.

⚠️ Attention: Do not interrupt the firmware update! If the bracelet turns off during the process, it may stop turning on. The average refresh time is 5-10 minutes. If the process is stuck at 0%, restart the bracelet and try again.

After the firmware update, the bracelet will automatically restart. Wait for the full load (the main menu will appear) and try to connect again.

What to do if the firmware update is suspended?

If the update process stalled for a few minutes and the indicator doesn’t move: 1. Turn off the bracelet from charging. 2. Reboot it forcibly (hold the touch button for 15 seconds). 3. Connect to charging and repeat the update. If the problem repeats, try updating the firmware through another smartphone (preferably on another OS – for example, if you have an iPhone, use Android, and vice versa).

4. Reset bracelet settings to factory

If previous methods have failed, it's time for a hard reset, which will remove all the data from the bracelet (steps, pulse, settings), but often helps restore performance.

On the bracelet, go to Settings → About the device.
Scroll down to Reset (or Reset).
Confirm the action by clicking the tick.
The bracelet will reset and return to factory settings.

After discharge:

🔄 The bracelet will be displayed as a new device in the app.
📱 You will need to re-link it to your Xiaomi account.
⚙️ All personal settings (alarm clocks, notifications) will have to be configured from scratch.

If the reset didn’t help, try an alternative method:

Turn off the bracelet from charging.
Hold the touch button for 20 to 25 seconds until the vibration and the Mi logo appear.
This is a forced reset that works even if the bracelet screen does not respond.

💡

Factory reset is a last resort, and try all other methods before you do, because after resetting, you will lose all the unsynchronized data (steps, sleep, workouts).

5. Bluetooth problems: diagnosis and solution

If the bracelet doesn't show up on the list of available devices or connects but shuts down immediately, the problem may lie in the phone's Bluetooth module.

Symptoms.	Possible cause	Decision
The bracelet is not visible on the list of devices	Bluetooth is disabled or is not operating smoothly	Turn on Bluetooth, restart your phone, check your energy saving settings
Connection breaks down in 1-2 seconds	Conflict with other connected devices	Disable all other Bluetooth gadgets (earphones, speakers)
The bracelet is connected, but the data is not synchronized	Outdated Bluetooth cache	Clear the module cache (instruction below)
The connection is only established after several attempts.	Interference from other wireless devices	Remove from sources of interference (Wi-Fi routers, microwaves)

For Android phones, an additional step is to clean up the Bluetooth cache:

Go to Settings → Applications → All applications.
Find Bluetooth (or Bluetooth Share).
Press Warehouse. → Clear the cache.
Reboot the phone.

On iPhone, the Bluetooth cache clears automatically when you restart, but if the problem persists, try removing the bracelet from the device list:

Go to Settings → Bluetooth.
Find Mi Band 5 in the list and click on the "i" icon next to the name.
Choose Forget this device.
Reboot your iPhone and try to connect again.

💡

If you have Android 12+, turn on developer mode and turn off the option Automatic Bluetooth Disconnection in the settings. This will prevent the connection from breaking due to battery optimization.

Conflicts with applications and OS

Sometimes the problem is not the wristband, but the software on the phone, and here are the most common scenarios.

🛡️ Antiviruses or firewalls block the connection. Try temporarily disabling the protection and check the connection.
🔋 Power saving modes limit Bluetooth. On Android, add Mi Fit to the optimisation exception list.
📱 Incompatibility of OS versions. For example, Mi Band 5 may not work correctly with Android 14 or iOS 17 without a firmware update.
🗃️ Damaged application data. Delete and reinstall Mi Fit/Zepp Life.

If you are using Android, check the permissions for the app:

Go to Settings. → Annexes → Mi Fit/Zepp Life → Permits.
Make sure it's on: 📍 Location (required for Bluetooth) 📱 Storage (for data storage) 🔔 Notifications (for synchronization of alerts)

On the iPhone, check:

Settings → Privacy → Geolocation Services – the application must have access When used.
Settings → Notifications → Mi Fit/Zepp Life – Enable Alert Permissions.

Before contacting the service center, try the last test:

Connect the bracelet to another phone (preferably on another OS).
If the connection on the second device was successful, the problem is in your smartphone.
If the bracelet is not connected to any device - a malfunction in the gadget itself.

Critical information: If the Mi Band 5 stopped connecting after falling, hitting or contacting water, don’t try to disassemble it yourself.

📅 Date of last successful synchronization.
📱 Phone model and OS version.

FAQ: Frequent questions about connecting Mi Band 5

🔹 The bracelet is plugged in, but it doesn't show notifications?

Check the notification settings in the Mi Fit app: Open your bracelet profile. Go to Notifications. Turn on the switch for the right apps (calls, SMS, instant messengers). On Android, also check the permissions for Mi Fit in your phone settings. If notifications still don't come, reboot the bracelet and phone.

🔹 Can you connect Mi Band 5 to two phones at the same time?

Officially, no. The bracelet is tied to one Xiaomi account and one device. But there's a workaround: Connect the bracelet to the first phone and sync the data. Untie it in the app settings. Connect it to the second phone. But note: when you reconnect, some of the data (like sleep history) can reset.

🔹 After the firmware update, the bracelet quickly discharged?

Yes, newer firmware versions sometimes optimize features, which can affect power consumption. Give the bracelet a 2-3 full charge/discharge cycle - the battery will "stall down." If the problem persists: Turn off unnecessary functions (for example, constant pulse monitoring). Reduce the brightness of the screen. Check if background sync processes (for example, with Google Fit) are running.

🔹 The bracelet vibrates when you plug it in, but it shuts off immediately?

This is a typical sign of Bluetooth conflict. Try: Remove the bracelet from the list of conjugated devices in the phone settings; clear the cache of the Mi Fit app (Android) or reinstall it (iOS); disable the VPN or firewall, which can block the connection; if it doesn't help, try connecting via another phone, this will help localize the problem.

🔹 Can I manually flash Mi Band 5 if the automatic update doesn't work?

Yes, but it's risky. Xiaomi doesn't officially provide firmware for manual installation, but enthusiasts post it on forums (like 4PDA). Instruction: Download the firmware for your version of the bracelet (check model number in Settings → About device). Install the Mi Band 5 Tools app (required Android). Connect the bracelet and follow the instructions in the app. Warning: Incorrect firmware can turn the bracelet into a "brick." Do this only if you'relied!
