The Xiaomi Mi Sport fitness bracelet (also known as the Mi Band 1S or Mi Band Pulse) remains a popular activity tracking device despite the release of new models, its main advantages are simplicity, long battery life and an accurate pulsemeter. However, many users have difficulties with the first connection, especially if it is a old version of firmware or incompatible smartphones.
In this article, you will find detailed instructions on how to connect Mi Sport to Android and iOS phones, including solutions to common bugs like βdevice not foundβ or βdata cannot be synchronized,β and we will also discuss which apps are best used for different versions of the bracelet and how to update the firmware if standard methods do not work.
If you bought a used bracelet or it was lying without use for a long time, be sure to reset it to the factory settings before connecting - hold the button 10-15 seconds before vibration. This will delete old data and simplify synchronization.
1.What models belong to the Xiaomi Mi Sport line?
The Xiaomi Mi Sport is often referred to as a number of first- and second-generation devices, and here are the key differences:
- π Mi Band 1S (Pulse) is the first version with a pulseometer (2015), compatible only with Mi Fit versions up to 4.6.
- π Mi Band 2 β Added a OLED- screen and touch button, requires Mi Fit 4.7+ or Zepp Life.
- π Mi Band HRX (India) - Modification of Mi Band 2 with different branding, connects similarly.
Important: Mi Band 3/4/5/6/7 is a different line, and you need different instructions for it. If your bracelet doesn't have the Mi Sport or 1S label on it, check the model in the documentation.
For the Mi Band 1S, there is a problem with modern smartphones, for example, on Android 12+ or iOS 15+, the original Mi Fit app may not see the device, in which case alternative software will be needed - read about this in the app section.
2. Preparation of the bracelet for connection
Before syncing with your phone, do the basic steps:
Charge the bracelet to 100% (the indicator is lit green)
Make sure your phone is on Bluetooth 4.0+
Reset the bracelet to factory settings (hold the button 10-15 seconds)
Remove old versions of Mi Fit or Zepp Life apps
Check the compatibility of the OS (Android 4.4+/iOS 9+)
-->
Pay special attention to resetting, if the bracelet has already been paired with another phone, the new data will not sync.
- Disconnect the bracelet from the charger.
- Find a physical button on the case (the Mi Band 1S has it hidden under the lid).
- Hold it until you feel three vibrations in a row (about 15 seconds).
- After resetting, the indicator flashes red - this means that the bracelet is ready for a new setup.
If the button doesn't respond, check the battery power. If it's below 10%, the reset may not work. Connect the bracelet to charge for 20 to 30 minutes and try again.

How to update the firmware on Mi Band 1S in 2026?
β οΈ Warning: If the bracelet stopped turning on after the firmware update (no vibration or indication), try resetting it by holding the button for 20 seconds. If this does not help, you will need to flash it through nRF Connect (you need skills with a Bluetooth debugger).
6. Alternative applications for Mi Sport
If the official software is not suitable (for example, due to the new version of Android), use third-party applications:
- π± Notify & Fitness for Mi Band β supports Mi Band 1S/2, works without registration, but requires manual notification settings.
- π± Mi Bandage is open source, compatible with older bracelets, but without cloud synchronization.
- π₯οΈ Gadgetbridge - for PC (Windows/Linux), allows you to flash the bracelet and customize it without a smartphone.
For installation of Notify & Fitness:
- Download APK from the official website.
- Allow installation from unknown sources in Android settings.
- Open the app and select "Add Device β Mi Band 1S".
- Follow the instructions on the screen (similar to Mi Fit).
Advantages of alternative applications:
- β Works on newer versions Android/iOS.
- β More settings (e.g. custom vibrations for notifications).
- β There is no binding to a Xiaomi account.
β οΈ Warning: Third-party apps may misread steps or calories due to the lack of original Xiaomi algorithms. For medical purposes (such as heart rate monitoring), it is better to use official software.
7. How to check the performance of the bracelet
If the bracelet is connected, but you doubt its serviceability, perform tests:
- Vibration test: In the app, select βFind the braceletβ β it should vibrate.
- Pulsemeter test: Put a wristband on your wrist and start measuring your pulse in Mi Fit. Normal values are 60-100 beats per minute.
- Pedometer Test: Take 20 steps β the counter in the app should be updated.
- Notification test: Send SMS or call your phone - the bracelet should vibrate.
If any of the tests are not passed:
- π Check the battery power (at a charge below 20%, some functions are turned off).
- π Reconnect the bracelet to the phone.
- π οΈ Update the firmware (if available).
The Mi Band 1S has a problem with false pedometer positives (such as when driving in a car) to reduce the error:
- Put the bracelet tighter on your wrist.
- In the Mi Fit settings, turn off the "Auto-Detection of Activity" option.
- Use manual mode to record training.
