How to connect Xiaomi Mi Band 3 to a smartphone: instructions with pictures and tips

The Xiaomi Mi Band 3 remains one of the most popular fitness bracelets even years after its release. Compact design, 20-day autonomy and a wide range of functionality — from sleep monitoring to notifications — make it a hot choice for beginners in the world of wearable electronics. However, many users have difficulties at the stage of first connection: the bracelet is not determined by the phone, the application does not see the device, or synchronization is interrupted at half the time.

In this article, we will discuss all the ways to connect the Mi Band 3 to Android and iOS smartphones, including solving common errors. We will focus on setting up notifications, updating firmware and optimizing power consumption – these nuances are often missed in standard instructions. If you only unpacked the bracelet or encountered problems after resetting, follow the step-by-step guide below.

Preparation for connection: what to check before starting

Before you start pairing, make sure that the basic conditions for successful synchronization are met, and neglecting these points leads to 70% of connection errors.

• 📱 Smartphone compatibility: Mi Band 3 works with Android 4.4+ iOS 9.0+. On devices with outdated versions of the OS, the Mi Fit or Zepp Life application may not be installed.
• 🔋 Bracelet charge: Battery level must be at least 20%. When the discharge is less than 10%, the bracelet goes into energy-saving mode and does not appear in the list of available devices.
• 📶 Bluetooth and geolocation: On Android, turn on Bluetooth, Geodata and location permission for the app. On iPhone, only activate Bluetooth.
• 🚫 Conflicting apps: Close other fitness trackers (e.g. Google Fit or Huawei Health) that may block the connection.

If you're connecting the bracelet for the first time, remove it from the package and remove the protective film from the sensor on the back. Charging contacts should be clean - wipe them with a dry wipe if necessary. The Mi Band 3 has no physical on button: it activates automatically when connected to the charger or when paired with a smartphone.

Mi Fit or Zepp Life – Which is Best for Mi Band 3

Xiaomi officially recommends Mi Fit, but since 2022, the company has been actively migrating users to a new app, Zepp Life (formerly Amazfit), both of which support Mi Band 3, but there are key differences:

For Mi Band 3, we recommend Zepp Life, as it is optimized to work with new versions of Android and iOS. However, if you are interested in integrating with Google Fit or Apple Health, check the sync settings in your profile – in Zepp Life they can be hidden in the submenu of Accounts → Linked Apps.

⚠️ Note: If you’ve used Mi Fit before, make sure to back up your data in the cloud before you switch to Zepp Life. When you first log in to a new application, the system will suggest moving your activity history, but this process does not always go smoothly.

Step-by-step: how to connect Mi Band 3 to Android

The pairing process on Android takes no more than 5 minutes if you follow the algorithm without skips. Below is the current instruction for Zepp Life (version 6.10.0 and later).

1. Install Zepp Life from Google Play. Avoid third-party APKs - they may contain viruses or outdated versions.
2. Sign up or sign in to your existing Xiaomi/Zepp account. This will be done with your email, phone number or Google/Apple profile.
3. Click Add Device → Select Bracelet → Mi Smart Band 3. If the model is not listed, update the app.
4. Allow the app to access Bluetooth, Notifications, and Geodata (required!) without these permissions, sync will be interrupted.
5. Wait until the bracelet appears on the list of available devices (it can take up to 30 seconds).
6. Once you've successfully connected, the app will offer you to update your firmware. Don't refuse, the new version fixes synchronization errors and adds new features.

If the bracelet is not displayed at the device search stage:

• 🔄 Reboot the Mi Band 3 by holding the touch button for 10 seconds before vibration.
• 📵 Turn off and turn on Bluetooth on your phone again.
• 🗑️ Clear the Zepp Life app cache in Android settings.

💡

If the bracelet plugs in but shuts down immediately, check your phone’s energy saving settings. Add Zepp Life to the battery optimization exception list (on Xiaomi: Settings → Battery → Battery Optimization → All apps → Zepp Life → No restrictions).

Connecting Mi Band 3 to iPhone: nuances for iOS

On the iPhone, the pairing process is similar, but there are 3 key differences:

1. The Zepp Life app requests access to Notices and HealthKit.Without HealthKit permission, steps and sleep data will not sync with Apple Health.
2. When you search for a device, the Mi Band 3 might be defined as MI Band 3 (without "Smart"). That's OK -- choose it boldly.
3. Once connected, go to iPhone → Bluetooth Settings and make sure the bracelet appears as Connected. If status is Not Connected, remove the device and repeat pairing.

iOS 16+ users may experience a "Disconnected" error.

1. Open Settings → Privacy → Geolocation Services.
2. Find Zepp Life and set permission When using it.
3. Restart the application and reconnect.

⚠️ Note: On iPhones with iOS 15 and below, Mi Band 3 may not display notifications from WhatsApp and Telegram correctly.This is a system restriction - Apple blocks access to notifications for third-party applications. Solution: use official messenger clients (not web versions).

Configure notifications and basic functions

After successful connection, adjust the key parameters to the bracelet works as efficiently as possible:

• 🔔 Notifications: In Zepp Life, go to Device Profile → Notifications. Enable the option to Show notifications and select the apps whose aerials will be duplicated on the bracelet. For Android, also activate Allow Autorun.
• 🌙 Sleep monitoring: Enable automatic tracking in Settings → Regimes → Sleep: Set a sleep schedule for accuracy (e.g. 23:00-7:00).
• 🏃 Activity objectives: B Profile → Set a daily rate of steps (recommended value of 8000 for beginners).
• 🔒 Screen lock: In Settings → Lock screen activate unlocking your phone through the bracelet (works only on Android with the help of the device). MIUI or EMUI).

To save charge, turn off unnecessary functions:

• 📊 Continuous pulse: In Settings → Set the measurement interval of 30 minutes instead of 1 minute.
• 📱 Raising your hand to activate: If the screen is switched on accidentally, deactivate the option in Settings → Display.

Firmware Update: Why It Matters and How to Do It Right

The Mi Band 3 firmware affects connection stability, sensor accuracy and support for new features, with the latest official version being 1.6.0.64 (at 2026).

1. Make sure the bracelet is >50% charge and connect it to the charger while you upgrade.
2. Open Zepp Life → Device Profile → Firmware Update.
3. If the update doesn’t appear, check your account region. Some firmware versions are distributed by region (e.g., Europe and Asia have different builds).
4. Do not interrupt!Switching off Bluetooth or closing the application can lead to a "brick" of the bracelet (loss of performance).

The average refresh time is 5-10 minutes, and when it's finished, the bracelet will reboot automatically.

• 🔌 Connect the bracelet to charging.
• 📶 Switch your phone to mobile internet (sometimes Wi-Fi blocks downloads).
• 🔄 Reinstall Zepp Life.

💡

Updating firmware through Zepp Life is safer than through third-party utilities (such as Mi Band Tools).
