Step-by-step connection of Xiaomi Mi Band 3 to a smartphone: from pairing to fine-tuning

Xiaomi Mi Band 3 remains one of the most popular fitness trackers due to its combination of affordable price, reliability and wide functionality. However, new users often have questions: how to connect the bracelet to the phone, what applications are needed for this, and what to do if the device is not determined by the system. In this article, we will analyze the entire process from unpacking to first synchronization of data, and also consider typical errors and ways to fix them.

It's important to understand that the Android and iOS connection process has nuances, from the operating system version to the smartphone model, and we'll take all of these things into account to make sure that the instruction is suitable for most devices. If you've tried to hide the bracelet but you haven't succeeded, look at the problem solving section, which contains unique recommendations for resetting the bracelet through a hidden menu that are not in the standard manuals.

What you need to connect

Before you start pairing, make sure you have everything you need. Here's the minimum set:

• 📱 Smartphone on Android 4.4+ or iOS 9.0+ (Older versions of the OS may not support the Mi Fit app).
• 🔋 Charged Mi Band 3 (charge level not lower than 20%, otherwise the bracelet may turn off during settings).
• 📲 The official Mi Fit app (you can download from the App Store or Google Play) is Zepp Life (formerly Mi Fit for some regions).
• 🔌 Bluetooth 4.0 or later (check in phone settings: Settings) → The phone. → Information on the PO).

If you have Android, we recommend turning off the power saving mode and battery optimization for the Mi Fit app, which will prevent connection breakage. On iPhone, make sure that Settings → Privacy → Geolocation Services for Mi Fit enable “When in use” access.

Installation and configuration of the Mi Fit application

The official Mi Fit app is the only reliable way to connect the Mi Band 3 to your phone. Alternative programs (such as Notify & Fitness or Tools & Mi Band) may not work smoothly or support all the features of the bracelet.

Download Mi Fit from the official store:

• 🤖 Google Play for Android
• 🍎 App Store for iOS

After installation, follow the following steps:

1. Open the app and select the language (we recommend English or Russian – other localizations can work with errors).
2. Sign up or sign in through your Xiaomi, Google, Facebook or Apple ID account. Without an account, data synchronization will not work!
3. Press "+" or "Add device" in the upper right corner.
4. Choose from the Mi Smart Band 3 list (not to be confused with Mi Band 4/5/6!).

Now, to the process of connecting, follow the instructions carefully, and skipping a step can lead to an error.

Step 1. Activate Mi Band 3:

• 🔘 Press the touch button of the bracelet - the screen should light up.
• 🔄 Scroll down to the item "Connect" (in English firmware - "Pair»).
• ✅ Confirm the choice by pressing the button.

Step 2. In the Mi Fit app:

• ⚠️ If the update is stalled, wait 10 minutes, then restart the bracelet.

Configure notifications and basic functions

Once you've successfully connected, we'll customize the bracelet to suit your needs.

• 🔔 Notifications: Select which apps will send alerts to the bracelet (calls, SMS, On Android, you may need additional permission in Settings → Annexes → Mi Fit → Notifications.
• 🕒 Alarm clocks: set the vibration alarms right in Mi Fit (up to 10) and they will work even if the phone is turned off.
• 🏃 Activity goals: Set a daily rate of steps (8000 by default, but you can change it to 10,000 or another value).
• 🔋 Screen: Choose whether the bracelet will show the time constantly or only when you raise your hand.

There is a limitation for the iPhone: notifications from third-party messengers (WhatsApp, Telegram) may not come due to Apple's policy: the solution is to use the alternative Notify & Fitness for Mi Band app (but it is paid).

💡

If notifications arrive with a delay, in the Mi Fit settings, turn off the option “Saving energy for notifications”.

We also recommend that you activate automatic synchronization of sleep and step data.

1. Open your profile in Mi Fit.
2. Go to Mi Smart Band 3 → Device Settings → Data Synchronization.
3. Turn on the autosynchronization option and set the interval (e.g. every 30 minutes).

Synchronizing data with other services

The Mi Band 3 can transmit activity data to popular fitness services like Google Fit, Apple Health, Strava, and others, which is useful if you use multiple training apps.

To enable synchronization:

1. In Mi Fit, go to Profile → Settings → Sync with other apps.
2. Select the service you want (like Google Fit) and log in.
3. Allow access to data on steps, sleep, pulse and training.

An important nuance: not all data is synchronized in both directions, such as Google Fit will receive steps from Mi Band 3, but will not relay the workout data recorded in other apps.

💡

To accurately count calories in Google Fit or Apple Health, make sure to include your real weight, height and age in Mi Fit. Without these data, the calculation will be inaccurate.

If the synchronization is not working:

• 🔄 Reboot your phone and bracelet.
• 🔧 Disable and reconnect the service account in Mi Fit.
• 📱 Check if the antivirus is blocking or VPN transmission.
