The Xiaomi Mi Band 3 fitness bracelet remains one of the most popular trackers even years after its release, thanks to a balance of functionality, sensor accuracy and affordable price. However, many users face difficulties when connecting or configuring the device for the first time. Unlike new models (Mi Band 7 or Smart Band 8), the three have their own nuances, from synchronization features with outdated versions of the Mi Fit app to compatibility limitations with modern smartphones.
This article will help you understand how to properly link the bracelet to your phone, adjust the basic functions (stepmeter, pulsemeter, notifications), and solve typical problems β from lack of communication to data display failures. We will look at current ways for Android and iOS, and give recommendations for optimizing the device in 2026.
Preparing for Connection: What to Check Before Starting Setup
Before you start syncing, make sure your smartphone and bracelet are ready to go, and problems often arise from small things like a dead battery, outdated software, or an incompatible version of an application.
Here is the mandatory checklist before connecting:
Charge the bracelet to 100% (charge indicator β flashing symbol of the battery on the screen)
Make sure your phone has the latest version of Mi Fit (or Zepp Life for new firmware) installed.
Enable Bluetooth and Geodata on your smartphone
Disable other wearable devices in Bluetooth settings (they can create conflicts)
Check Compatibility: Mi Band 3 is running Android 4.4+ iOS 9.0+, But on the new iPhone (series 15) may be limited-->
Pay special attention to the firmware versions of the bracelet. If the device was lying unused for a long time, its software could become outdated, in which case, after connecting, you will need to update the firmware through the application, otherwise some functions (such as monitoring sleep or notifications) may not work properly.
β οΈ Note: On iOS, you may need to allow Mi Fit to access Health and Notices when you first connect. Without it, the bracelet will not be able to sync your steps and pulse data.
How to connect Mi Band 3 to your phone
The process of pairing the bracelet with the phone takes no more than 5 minutes, if you follow the algorithm. Let's consider two options: for Android and iOS.
For Android.
1 Download and install the Mi Fit app from Google Play. The alternative is Zepp Life (formerly Amazfit), but it doesn't support all the three-piece features.
2. Sign up or sign in to your Xiaomi account (required! without an account, the bracelet will not sync).
3. Turn on Bluetooth on your phone and start Mi Fit. Click Profile β Add Device β Bracelet β Mi Smart Band 3.
4. The bracelet should appear in the list of available devices. Click on it and confirm the connection on the tracker itself (touch the bracelet screen when the request appears).
For iOS (iPhone)
The iPhone algorithm is similar, but there are nuances:
- π± Mi Fit app can request access to Notifications β allow, otherwise the bracelet will not vibrate when calling.
- π After connecting, go to the iPhone Settings β Bluetooth and find Mi Band 3 in the list. Click on the "i" icon next to the device and enable Contact Sync (if you need call notifications).
- π« On iOS 16.+ Notifications from some messengers (e.g. Telegram) may not work, which is a restriction of Apple, not the bracelet.
If the bracelet is not present, try:
- π Reboot the bracelet (press the touch button for 10 seconds until the Mi logo appears).
- π± Restart Bluetooth on your phone.
- π Remove the bracelet from the list of devices in Mi Fit and reconnect.
Customization of the main functions: pedometer, pulse, notifications
Once you've successfully connected, you need to customize the bracelet to suit your needs, and let's look at the key functions and their configuration.
1. Monitoring activity (steps, calories, distance)
By default, the bracelet counts steps and calories, but the accuracy depends on the correct settings:
- π In Mi Fit go to Profile β Mi Smart Band 3 β Steps and specify your height, weight and step length (default 70 cm for men and 60 cm for women).
- π Enable Activity Autodetermination (Walking, Running, Bicycling Recognition).
- π Set a daily goal (8000-10,000 steps recommended).
2. Measurement of pulse and sleep
The Mi Band 3 can measure your heart rate manually and automatically (including during sleep).
- β€οΈ Turn on pulse automonitoring in bracelet settings (interval: every 30 minutes or 1 hour).
- π΄ Activate Sleep Monitoring β the bracelet will track sleep phases (deep, light, awakenings).
- π In Mi Fit you can see the charts of heart rate and sleep for a week / month.
π‘
If the bracelet miscalculates steps (e.g., in transport), turn off Activity Autodetermination and use manually starting workouts through the bracelet menu (More β Training).
3. Notifications of calls and messages
To make the bracelet vibrate when incoming calls and messages:
- In Mi Fit, go to Notifications β Notification Management.
- Turn on Show notifications and select apps (such as WhatsApp, Viber, SMS).
- On Android, allow Mi Fit to access notifications in your system settings (Settings β Applications β Mi Fit β Notifications).
β οΈ Note: Some Xiaomi smartphones (e.g. Redmi Note) 10/11) Notifications may not come due to energy saving settings. Add Mi Fit to the AutoRun list and turn off battery optimization for this app.
Firmware Update: Why It Matters and How to Do It
Mi Band 3 firmware affects the stability of the work, the accuracy of sensors and compatibility with new versions of Mi Fit. If the bracelet is glitzy (for example, does not sync data or discharge quickly), the first thing to do is to update the software.
How to check and update the firmware:
- Open Mi Fit and go to Profile β Mi Smart Band 3 β Firmware Update.
- If a new version is available, click Update. During the update, do not turn off Bluetooth or remove the bracelet from the range of the phone - this can lead to the "bricking" of the device.
- Wait until it is completed (usually 5-10 minutes) and the bracelet will reset automatically.
Up-to-date firmware versions for Mi Band 3 (June 2026):
| Firmware version | Release date | Major changes |
|---|---|---|
| 1.6.0.54 | November 2023 | Corrected bugs with sleep synchronization, improved accuracy of the pulse meter |
| 1.5.1.48 | March 2023 | Added support for new smartphones on Android 13 |
| 1.4.0.36 | July 2022 | Optimized power consumption, corrected errors with notifications |
What to do if the update is suspended?
Resetting settings and problem solving
If the bracelet is unstable (not synchronized, not showing notifications, quickly discharged), a factory reset can help.This will delete all data from the device, but often solves software failures.
How to Reset Mi Band 3:
- On the bracelet, go to More β Settings β Reset (or Reset).
- Confirm the action by pressing the screen.
- After restarting, reconnect the bracelet via Mi Fit.
Typical problems and their solutions:
| Problem. | Possible cause | Decision |
|---|---|---|
| The bracelet is not synchronized. | Outdated firmware or conflict with another device | Update, remove other bracelets from Bluetooth |
| No notifications coming. | No access to notifications on the phone | Check your Mi Fit settings and permissions in the system |
| The battery goes down fast. | Frequent auto-monitoring of the pulse or outdated firmware | Reduce the interval of pulse measurement or update the software |
| Wrong step counting | Incorrectly specified height/weight or bracelet worn loosely | Update the data in the profile and tighten the strap |
