The Xiaomi Mi Band 2 fitness bracelet remains a popular gadget among Android smartphone users due to its simplicity, reliability and affordable price. However, connecting the device to a Xiaomi phone (especially on custom firmware such as MIUI) sometimes causes difficulties, from synchronization errors to problems with displaying notifications. In this article, we will analyze the step-by-step instructions for connecting the Mi Band 2 to Redmi, POCO and other Xiaomi phones, and consider common errors and how to fix them.
If you just purchased a bracelet or experienced problems after resetting, this guide will help you set up your device from scratch. We have taken into account all the nuances of working with MIUI, including the limitations of the background for applications and the features of Bluetooth connection.
1. Connection Preparation: What to Check Before Synchronization
Before you start connecting the Mi Band 2, make sure your smartphone and bracelet are ready to sync, and skipping this step often leads to errors like “Disconnected” or “Not detected bracelet.”
First, check out the Android and MIUI version on your phone. Mi Band 2 officially supports Android 4.4 and higher, but Android 6.0+ is recommended for stable operation. Xiaomi smartphones with MIUI 12/13/14 may have problems with the background work of the Mi Fit application - we will discuss this later.
Second, make sure the bracelet is at least 20% charged. The charge indicator on the Mi Band 2 lights up when connected to the charger. If the indicator doesn't blink, try another one. USB-port or cable – sometimes the problem lies in a faulty connector.
- 📱 Android version: minimum 4.4, optimally 6.0+
- 🔋 Bracelet charge: at least 20% (at 5% and below synchronization may be interrupted)
- 📲 Free space: The phone must have at least 500MB to install Mi Fit and cache
- 🔄 Bluetooth: enabled and visible for other devices (check Settings) → Bluetooth)
If you have previously used another fitness bracelet (such as Mi Band 3/4), remove it from the Mi Fit app before connecting Mi Band 2.
2. Installation and configuration of the Mi Fit application
The official Mi Band 2 management app is Mi Fit (Humami developer), which can be downloaded from Google Play or AppGallery (for Huawei devices), but Xiaomi smartphones with MIUI are better off using the version from Google Play, as it is less likely to conflict with system restrictions.
After installation, follow the following steps:
- Open Mi Fit and select the language (Russian is available).
- Click on “Sign in” or “Sign in” if you already have a Xiaomi account.
- Enter the login details (email or phone number) and confirm with the code from SMS.
- After authorization, click "Add device" and select "Breasure" → "Mi Smart Band 2".
Note: If you don’t have a Mi Account, you can create it directly in the app, but for full-time work (for example, synchronizing data with Mi Cloud), you need to link to the account.
☑️ Preparing Mi Fit for Connection
On Xiaomi phones with MIUI 12+ after installing Mi Fit, you must manually allow the application to work in the background:
- Go to Settings → Applications → Application Management → Mi Fit.
- Select "Permissions" and turn on "Location", "Bluetooth", "Storage".
- Go back and press "Battery" → "No restrictions".
- Activate the Auto Start option (this will allow Mi Fit to work after the phone is restarted).
3. Step-by-step connection of Mi Band 2 to Xiaomi phone
Now, to the synchronization process itself, follow the instructions carefully, and skipping even one step can cause a failure.
- Activation of the bracelet: Press the touch button Mi Band 2 (under the screen) before vibration.
- Device search: In the Mi Fit app, click "Plug in" and wait for the phone to find the bracelet. If the Mi Band 2 doesn't appear in the list, update the search or restart the Bluetooth on the phone.
- Pair: The phone will have a code identical to the one on the bracelet. Confirm pairing on both devices.
- Firmware update: Once connected, Mi Fit will offer to update the bracelet firmware.Agree only if the Mi Band 2 charge is above 50% - interrupting the update can bring the device down.
If at the interface stage there is an error "Can not connect", try the following actions:
- 🔄 Reboot Bluetooth on your phone (Settings) → Bluetooth → Off./On.).
- 📱 Remove Mi Band 2 from the list of conjugate devices in Bluetooth settings and reconnect.
- 🔌 Reset the bracelet: plug it into charging, wait for vibrations, then turn it off and try to connect again.

4. Set up notifications and basic functions
Once you've successfully connected, customize the Mi Band 2 to your needs.
| Function | How to set up | Recommendations |
|---|---|---|
| Call notifications | Profile → Notifications → Incoming calls | Turn on vibration and screen lights for important contacts |
| Messenger alerts | Profile → Notifications → Applications (select the right ones) | Disable unnecessary applications to avoid wasting charge |
| Alarm clock | Profile → Alarm clocks → Add an alarm clock. | Set up repeated alarm clocks for work days |
| Activity targets | Profile → Goals → Steps / Calories / Sleep | Set realistic goals (e.g., 8,000 steps a day) |
| Lock screen | Profile → Unlock the phone | It only works on Android 5.0+ and MIUI without Root |
On Xiaomi smartphones with MIUI, notifications may not arrive due to battery optimization.
- Go to Settings → Applications → Application Management → Mi Fit → Battery.
- Select "No Limits" and turn on "Stop".
- In Settings → Notifications → Mi Fit, allow notifications to be displayed on the lock screen.
💡
If notifications come with a delay, turn off the power saving mode in Mi Fit: Profile → Additional → Energy saving → turn off the option.
5. Common mistakes and their solutions
Even with the right connection, Mi Band 2 users face typical problems, and let’s look at the most common ones and how to fix them.
⚠️ If the bracelet is no longer responsive to touch after the firmware update, reset it to factory settings: press the touch button 10 seconds before vibration.
| Problem. | Possible cause | Decision |
|---|---|---|
| The bracelet is not synchronized. | Conflict with another device in Mi Fit | Remove all devices from your account and reconnect Mi Band 2 |
| Notifications don't come in. | MIUI Limitations for Background Processes | Set up Auto Start and Turn Off Battery Optimization for Mi Fit |
| Bracelet discharges quickly | Too frequent synchronization or lighting on | Turn off unnecessary notifications and reduce screen brightness |
| Wrong time on the bracelet | Failure to sync with the phone | Reconnect the bracelet or update the firmware through Mi Fit |
If Mi Band 2 is connected but the data is not updated (steps, sleep, pulse), try:
- 🔄 Reboot your phone and bracelet.
- 📱 Remove the Mi Fit app cache (Settings) → Annexes → Mi Fit → Warehouse → Clear the cache).
- 🌐 Switch from Wi-Fi to mobile Internet (sometimes problems are caused by blocking Xiaomi servers in the local network).
On phones with MIUI Global, sometimes changing the region to India in the phone settings (Settings → Additional → Region) helps. This is due to the peculiarities of Xiaomi servers in different countries.
6. Alternative applications for Mi Band 2
If Mi Fit is unstable or you lack features, you can use third-party apps. They offer advanced notification settings, widgets and even support for Google Fit.
The most popular alternatives are:
- 📊 Notify & Fitness for Mi Band – Supports custom notifications, widgets and sync with Google Fit.
- 🔧 Mi Band Master – allows you to adjust vibrations, lock screen and alarms flexibly.
- 🌐 Tools & Mi Band – a utility for firmware bracelet and changing fonts.
Important! When using third-party apps, turn off automatic sync in Mi Fit to avoid conflicts, and be careful with firmware from third-party developers - they may deprive the bracelet of warranty.
To install an alternative application:
- Download APK from the official website (for example, Notify & Fitness).
- Allow installation from unknown sources (Settings → Applications → Special Rights → Installation of Unknown Applications).
- Connect the bracelet through the new app by following the instructions on the screen.
💡
The side of the app may offer more features, but official support and firmware updates are only available through Mi Fit.
7. Optimize the Mi Band 2 to save charge
Mi Band 2, when used actively, holds a charge for about 10–14 days, but if the settings are wrong, it can discharge in 3–5 days.
- 🔋 Turn off unnecessary notifications: leave only calls and important messengers (WhatsApp, Telegram).
- 🌙 Reduce synchronization frequency: In Mi Fit, set automatic synchronization once every 30 minutes instead of 5.
- 📵 Turn off the screen lighting: in the bracelet settings, select "No backlight" or "Short".
- 🏃 Use the power saving mode: in Mi Fit, activate the option "Energy saving" (limits background processes).
Also make sure that the bracelet is not in the zone of strong electromagnetic interference (for example, near the router or microwave) – this can lead to frequent reconnections and battery consumption.
If the bracelet discharges in less than 3 days, check it for physical damage (such as moisture falling under the body), in which case it may be necessary to replace the battery.
8.Reset Mi Band 2 to factory settings
If the bracelet is unstable (it doesn’t sync, doesn’t respond to touch), you may need to reset to factory settings.This will delete all data from the device, so pre-sync it with the Mi Fit.
Method 1: Through the Mi Fit application
- Open the Mi Fit and go to the bracelet profile.
- Click "Device Settings" (Icon) ⚙️).
- Select "Resetting" and confirm the action.
Method 2: Hardware reset
If the bracelet is not connected to the phone:
- Connect the Mi Band 2 to the charger.
- Press the touch button for 10-15 seconds before vibration.
- Release the button and the bracelet will reset and reset.
⚠️ Attention! When you reset, the bracelet will go back to the default firmware. If you upgraded it with Mi Fit, you'll have to do it again.
💡
If the bracelet doesn’t connect after reset, try connecting it to another phone (such as friends or relatives) to help identify a problem in your phone or bracelet.
