The Xiaomi Mi Band 4 remains one of the most popular fitness bracelets even years after its release, but over time, the device can start to glittle: not sync with the phone, not display data correctly or stop responding to touch altogether, and in 90% of these cases, a complete reset to factory settings helps - a procedure that returns the bracelet to its original state, as after purchase.
In this article, you will find three working reset methods (including hidden service mode), a table with reasons for resetting, and instructions for recovering data after the procedure. We will analyze the nuances for different versions of the firmware and warn against typical errors that can turn the bracelet into a βbrick.β If your Mi Band 4 freezes, does not turn on or simply requires βcleaningβ, read on.
When you need to reset Mi Band 4: 5 clear signs
Factory resetting is not a panacea, but in some cases it is the only way to bring the bracelet back to life.
- π The bracelet does not sync with the Mi Fit or Zepp Life app (errors like βDevice disabledβ or βUnable to connectΒ»).
- π± The screen does not respond to touch or reacts with a delay (even after rebooting).
- π Fast battery discharge (bracelet sits down in a few hours when fully charged).
- π Steps, pulses, or sleep are not displayed correctly (e.g. 10,000 steps in 5 minutes).
- π Bracelet blocked after failed firmware or phone change.
If your Mi Band 4 is just βslowing downβ, try rebooting it first (hold the 10 seconds button).
Method 1: Reset via Mi Fit or Zepp Life (official method)
This is the safest and most recommended method, as it does not require manipulation of buttons or hidden menus.
Instructions:
- Open the Mi Fit app (or Zepp Life for newer versions).
- Go to the Profile section β Mi Smart Band 4.
- Scroll down and select Untie the device.
- Confirm the action - the bracelet will automatically perform the reset.
β οΈ Warning: If the bracelet does not reset after detachment (the screen continues to burn), perform a forced reset: hold the button for 15 seconds until the Mi logo appears.
Make sure the bracelet is at least 50% charged.
Disconnect it from other devices (if connected to multiple phones)
Remember or take pictures of your current settings (alarm clocks, notifications)
Update the Mi app Fit/Zepp Life to the latest version-->
Method 2: Hardware reset via button (if bracelet does not respond)
If the Mi Band 4 is getting stuck, not activated or detected in the app, hard resetting through a physical button will help, which works even on a discharged bracelet (if at least 10% of the charge remains).
Step-by-step:
- Remove the bracelet from your hand and place it on a flat surface.
- Find the touch button below the screen (not to be confused with the charging connector!).
- Hold the button for 20 to 25 seconds until you feel the vibration and see the Mi logo.
- Release the button and the bracelet will start the reset process (it will take ~1 minute).
πΉ Signs of a successful reset: the screen blinks, the bracelet vibrates 3 times, then reboots with factory settings (the default language is English).
What if the bracelet does not respond to the button holding?
Method 3: Hidden Service Mode (for Power Users)
This method is suitable if the standard methods did not work or you need to reset the settings without detachment from the account. The service menu allows you to reset the bracelet at the firmware level, but requires accurate actions.
How to enter service mode:
- Go to the bracelet menu by swiping the screen to the right to More (or βMoreβ).
- Slip on the Settings icon.
- Scroll down and click About ("About the device").
- Slip the firmware number 5 times in a row (the inscription Developer mode enabled should appear).
- Return to the main menu and hold the screen at More 10 seconds, the hidden menu will open.
- Select Factory Reset and confirm the action.
β οΈ Note: Do not change other options in the service menu (such as Test Mode or Calibration) β this may result in loss of sensor calibration or firmware failure.
1. Remove it from the device list in the phone's Bluetooth settings.
2.Reinstall the Mi Fit/Zepp Life app.
3. connect from another phone (for verification).-->

| The bracelet is not synchronized. | Bluetooth or software failure | Yes (unless the reboot worked) | Reinstall the application, change the phone |
| The screen doesn't respond to touch. | Firmware getting stuck | Yeah (hard reset) | Waiting for the battery to run (sometimes helps) |
| Fast battery discharge | Background processes or sensor failure | Yes (unless calibration helps) | Disable unnecessary notifications |
| Incorrect steps/pulse data | Sensor failure | Yes (with subsequent calibration) | Reset statistics in the app |
| Bracelet locked after firmware | Incompatible version of the software | Yes (required) | Remove the firmware through Mi Band Tools |

Typical Resetting Mistakes and How to Avoid Them
Even a simple reset procedure can go wrong, if you don't take into account the nuances, and here are the most common user errors:
- β‘ Reset on discharged bracelet - if the charge is below 20%, the device can turn off in the process and "brickle." Solution: charge up to 50% before reset.
- π΅ Interrupting the process (e.g., turning off Bluetooth or closing the application) Solution: Do not touch the phone until the bracelet restarts.
- π Use of outdated versions of applications (Mi Fit below) 4.6.0 Or Zepp Life below. 5.0). Solution: Update the app on Google Play/App Store.
- π Attempt to reset via third-party utilities (e.g. Notify & Fitness) Solution: use only official methods.
If the bracelet does not turn on after reset or is stuck on the logo, try:
- Connect to charging for 1 hour (even if the indicator does not burn).
- Hold the button for 30 seconds on charging.
- If nothing helps, contact the service (may be a memory problem).
