How to turn on and configure the fitness bracelet Xiaomi Mi Band 3: full instructions in Russian

Xiaomi Mi Band 3 remains one of the most popular fitness bracelets even years after its release, thanks to a combination of affordable price, reliability and wide functionality. However, new users often have questions about how to properly turn on the device, sync it with a smartphone and avoid typical configuration errors.

Unlike the newer models (Mi Band 4/5/6), the third version has its own features: a different way to connect to the application, limited firmware support and unique control gestures. We will discuss each step in detail, from unpacking to solving synchronization problems, as well as give tips on extending battery life and optimizing the operation of sensors.

If you have just purchased a bracelet or pulled it out after a long downtime, this guide will be your guide, and we will pay special attention to the first turn on, updating the firmware and adjusting notifications - these are the points that cause the most questions for owners.

1.Preparation for the first turn on: what to check before launch

Before you press the button on the bracelet, make sure everything is ready for the device to work properly. Xiaomi Mi Band 3 requires minimal preparation, but skipping even small parts can lead to failures.

First, check the completeness: the box should contain the bracelet itself, the charging cable (no power supply!), and a brief instruction in several languages (Russian may not be available). If the cable is not, it is a fake or used device. The original cable has a magnetic connector and Xiaomi markings.

Second, prepare your smartphone:

• 📱 Operating system: Android 4.4+ or iOS 9.0+. On older versions, the Mi Fit app will not install.
• 🔋 Battery charge: A smartphone should have at least 20% charge – synchronization consumes energy.
• 📶 Internet: To download the application and firmware bracelet you need stable Wi-Fi or mobile Internet.
• 🚫 Restrictions: Disable VPN, ad blockers and energy saving modes – these can interfere with the connection.

Also worth considering is that the Mi Band 3 doesn’t have built-in GPS — it uses smartphone data to track routes. If you’re interested in autonomous navigation, consider the Mi Band 5 or later.

2. How to turn on Xiaomi Mi Band 3: step-by-step instructions with a photo

The process of turning on the bracelet is extremely simple, but there are nuances that are not written about in the short guides.

1. Charge before first turning on. Connect the bracelet to the charging cable (the magnetic connector should stick to the back panel). The charging indicator will light up red. Wait until it turns green (about 1-2 hours). Do not turn on the bracelet while charging - this can cause calibration of the battery to fail.
2. Activate with a button. After charging, press the single physical button under the screen and hold it for 3-5 seconds. The Mi logo will appear on the screen, then the main menu.
3. Select the language. Swipe the menu up/down (a gesture for all Mi Bands), find a item with the Russian flag or the words "Russian" and confirm the choice with the press of a button.
4. Time synchronization: The bracelet will automatically request time data when you first connect to your phone. If time is lost, check your time zone settings in Mi Fit.

If the bracelet does not respond to the button:

• 🔌 Check if it is sufficiently charged (the indicator must be green).
• 🔄 Try restarting the device: plug in to charge, hold the button for 10 seconds, then turn it off and turn it on again.
• 📱 Make sure that the smartphone is enabled Bluetooth (the bracelet connects only on it).

3. Connection to a smartphone: Mi Fit installation and synchronization

Without the Mi Fit app (or its alternatives, such as the Mi Band Master), the bracelet will only work like a pedometer clock.

1. Installation of the app: 📥 Download Mi Fit from Google Play or the App Store. 📝 Sign up or sign in via your Xiaomi account (you can use Google/Facebook). 🔄 Update the app to the latest version - older versions may not support Mi Band 3.
2. Adding device: 🔍 In Mi Fit, click Profile → Add Device → Bracelet → Mi Smart Band 3. 📱 Allow the app to access notifications, contacts and location (necessary for proper operation). 🔗 The bracelet will request connection - confirm it with the click of a button.

Profile setting

• ⚖️ Specify your weight, height, age and gender for accurate calorie and sleep counts.
• 🏃 Select your goals by steps (we recommend starting with 6,000–8,000 per day).
• 🔔 Set up notifications: In Device Profile → Notifications, select applications that will duplicate the alerts on the bracelet.

If the bracelet is not connected:

• 🔄 Reboot both the bracelet and the smartphone.
• 📱 In your smartphone’s Bluetooth settings, remove all previously saved Mi Band devices.
• 🔌 Try connecting from another phone – this will help to identify the problem (in the bracelet or smartphone).

💡

If after connecting the bracelet constantly vibrates - reset it to factory settings: in Mi Fit go to the Device Profile → Additional → Reset.

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

The Mi Band 3 firmware affects the stability, accuracy of sensors and support for new features. Xiaomi regularly releases updates, but they are not always installed automatically.

1. Check the current version: 📱 Open Mi Fit, go to Profile → Mi Smart Band 3 → Firmware Update. 🔍 The current version is displayed at the top of the screen (e.g. 1.6.0.54).
2. Search for updates: 🔄 Click on "Check Updates." If a new version is available, the Update button will appear. 📶 Make sure the smartphone is connected to Wi-Fi - the update weighs 5-15 MB.

Installation process

• ⏳ It's going to take 5-10 minutes to update, and don't turn off the bracelet or close the Mi Fit.
• 🔋 The bracelet must be at least 50% charged, otherwise the upgrade will be interrupted.

The latest stable firmware for the Mi Band 3 is 1.7.1.44 (at 2026).If your version is lower, upgrade by all means: new firmware fixes errors with:

• 🩺 Accuracy of pulse measurement (older versions had false positives).
• 🔔 Loss of communication with the phone (the bracelet stopped vibrating at notifications).
• 🕒 An alarm clock malfunctions (sometimes not working).

5. Basic features and setup: what does Mi Band 3 know

Xiaomi Mi Band 3 offers a wide range of functionality despite its budget positioning.

Activity tracking:

• 🚶 Stepmer: automatically counts steps. Accuracy can be improved by specifying the step length in Mi Fit → Profile → Pedometer settings.
• 🏃 Training modes: running, cycling, swimming (waterproof bracelet up to 50 meters). To activate swipe up on the home screen and select the sports icon.
• 💤 Sleep monitoring: captures the phases of deep and superficial sleep, and for accurate data, wear a bracelet on your non-working arm.

💡

To measure your pulse accurately, wear a wristband 2-3 fingers above your wrist and tightly but without squeezing your skin. Measurements in motion (such as running) may be less accurate.
