Why you need Bluetooth in Mi Band 3
The 2018 Xiaomi Mi Band 3 fitness bracelet is still popular with users due to its combination of functionality and affordable price, but many owners are faced with the question of how to turn on Bluetooth on this device if there is no explicit option on the menu to activate the module.
Unlike modern models (such as Mi Band 7 or Mi Smart Band 8), where the communication setting is made in a separate menu, the third version of the bracelet is as simple as possible - but this is often confusing. In this article, we will discuss not only the standard way of connecting, but also the solution to typical problems: why the bracelet is not visible in the list of devices, how to reset the communication settings and what to do if the Mi Band 3 refuses to sync with the Mi Fit or Zepp Life application.
Particular attention will be paid to the hidden pairing mode, which is activated when you press the touch button of the bracelet for a long time - this technique is not known by all users, although it often helps in cases where the standard connection does not work.
Preparing for Connection: What to Do Before Turning On Bluetooth
Before you try to turn on Bluetooth on the Xiaomi Mi Band 3, make sure the basic conditions for successful pairing are met.Neglecting these steps is the main reason why the bracelet doesn't connect to the phone.
- 📱 Install the official application: Mi Fit (for the Android/iOS) You can download only from Google Play or the App Store — third-party sources may offer outdated or modified versions.
- 🔋 Charge the bracelet: the charge level should be at least 20%. with low charge, the Mi Band 3 may not appear in the list of available devices.
- 📶 Turn on Bluetooth on your smartphone: check that the module is active in the phone settings (path: Settings) → Connections → Bluetooth for Android or Settings → Bluetooth for iOS).
- 🔄 Update the bracelet firmware: outdated software can cause conflicts when pairing. Check the relevance of the version in the application.
Also worth considering that Mi Band 3 supports Bluetooth 4.2, so for stable operation it is recommended to use a smartphone with a Bluetooth version at least 4.0. On very old devices (for example, with Bluetooth 2.1), connection problems may occur.
Standard way to turn on Bluetooth: step-by-step instructions
In Xiaomi Mi Band 3, Bluetooth activates automatically when you first connect to your phone. You don't have to look for a separate option in the bracelet menu, just pair it through the app. Here's how to do it:
- Open the Mi Fit or Zepp Life app and log in (if you haven’t already).
If it's a success, the bracelet vibrates, and the app will have a master panel with the data, and now Bluetooth on the Mi Band 3 is on and will automatically connect to the phone when they approach.
☑️ Preparation for interface
Importantly, if the bracelet has already been paired with another phone, it must first untie it from the old device, either through the app on the old smartphone (in the bracelet settings) or by resetting the Mi Band 3 to the factory settings.
Alternative method: forced Bluetooth on via hidden menu
In some cases, standard pairing doesn't work -- for example, if the bracelet was previously connected to another phone but not untie correctly -- then the hidden mode of forced pairing will help:
This method works in 90% of cases when the bracelet is not visible to the phone, and if it does not help, the problem may lie in a software failure, then you will need to reset the settings.
What if the bracelet does not respond to prolonged pressing?
Why Bluetooth on Mi Band 3 doesn’t work
Even after successful pairing, users sometimes find that the connection between the wristband and the phone is interrupted or not established at all.
| Problem. | Possible cause | Decision |
|---|---|---|
| The bracelet is not visible on the list of devices | Bluetooth is disabled on your phone or the bracelet is discharged | Charge Mi Band 3 to 50%, turn on Bluetooth on your phone, reboot both devices |
| The connection is interrupted at the confirmation stage. | Conflict with other connected devices | Disconnect all unnecessary Bluetooth devices from your phone, try again |
| The bracelet is connected, but the data is not synchronized | Outdated firmware bracelet or application | Update Mi Fit/Zepp Life and Mi Band 3 firmware through the app |
| Bluetooth is turned on, but communication is unstable | Interference from other wireless devices | Remove the bracelet from the phone’s device list and pair again |
If none of these things worked, try resetting the bracelet to the factory.
- Go to the bracelet menu (swipe up on the main screen).
- Find More → Reset (may be called Reset in Russian).
- Confirm the reset by pressing the touch button.
⚠️ Warning: Resetting will remove all data from the bracelet, including steps, sleep history and alarm settings. After reset, you will need to reconfigure the Mi Band 3 through the app.
Compatibility with different smartphones: nuances for Android and iOS
While Xiaomi Mi Band 3 officially supports both platforms, there are differences in the connection process and stability of the work:
Connecting to Android
Most smartphones running Android 6.0 and later pair without problems, but custom firmware devices (e.g. MIUI, ColorOS) may have conflicts over optimizing power consumption to avoid communication breaks:
- 🔄 Add Mi Fit to the battery optimization exception list (path: Settings) → Battery → Optimizing the battery → All applications → Mi Fit → No restrictions).
- 📴 Turn off the energy saving mode during pairing.
- 🔗 In Bluetooth phone settings, enable Visibility for all devices (at connection time).
Connection to iPhone (iOS)
On the iPhone, the pairing process is easier, but there are limitations:
- 🍎 Call and message notifications on Mi Band 3 only work for standard applications (Phone, Messages). WhatsApp, Telegram and other messengers will need to enable notifications in iOS settings (Settings). → Notifications → Select an application → Allow notices).
- 🔒 After the iOS update, you may need to re-conjugate the bracelet.
- 📱 On iPhone, you can not change the melody of the alarm clock on the bracelet – only standard signals are available.
💡
If the iPhone bracelet connects but doesn’t sync data, try disabling the VPN or changing the App Store region to China (temporarily), which helps in cases where Xiaomi servers are blocked in your region.
Firmware Update: Why it’s important for stable Bluetooth
Many Bluetooth issues on the Mi Band 3 are solved by a firmware update. Xiaomi regularly releases patches that fix pairing errors, especially for international versions of the bracelet (with firmware 1.0.9.14 and later).
To update the firmware:
- Open the Mi Fit or Zepp Life app.
- Go to the profile of the bracelet (stamp its icon on the home screen).
- Select the firmware update (if the option is available).
- Confirm the boot and wait for the process to be completed (the bracelet will reboot automatically).
Important: during the upgrade, do not disconnect the bracelet from the phone and monitor the charge level (should be at least 50%).
⚠️ Warning: If the bracelet has stopped responding to touch or is not turned on after the update, perform a hard reset: connect it to charging and hold the touch button for 20-30 seconds until the Mi logo appears.
💡
Regular firmware updates not only improve Bluetooth stability, but also add new features (e.g. support for additional languages or fixing data synchronization errors).
