The Mi Band series fitness trackers are deservedly considered one of the most popular wearable devices in the world due to their availability and functionality. However, like any complex electronics, the Xiaomi Mi Band 4 can face software glitches, freezes or synchronization problems with a smartphone. Often the only effective solution is a complete data reset, returning the gadget to the state of “out of the box”.
Many users are afraid to clean up for fear of losing statistics or locking the device forever. In fact, the process of returning to factory parameters in the Mi Band 4 is as simple as possible and takes only a few minutes. In this article, we will discuss all the available methods, from regular menu functions to forced reboot.
Before you start taking action, it is important to understand that resetting erases all local data stored directly in the wristband memory.This includes unsaved training data, dial settings and alarm clock settings. Synchronizing with the Mi Fit (or Zepp Life) app before starting the procedure is a must-do step to save your activity history.
Preparation of the device for the cleaning procedure
Before you start the reset process Xiaomi Mi Band 4, There are a number of preparatory steps that need to be taken, and ignoring this stage can cause you to lose important health data that can't be uploaded to your cloud profile. 20-30%, so that the device does not turn off at a critical moment.
Open the Mi Fit or Zepp Life app on your smartphone and go to the main profile page of the tracker. Click on the Sync button (usually a circle arrow or a swipe down) and wait for the data transfer to end. Only after you see the current date and time of the last sync, you can proceed to the next step.
⚠️ Warning: If you plan to sell the device or transfer it to another person, make sure to unbind the app before resetting.This will break the connection with your account and allow the new owner to link the bracelet to their profile without errors.
It’s also worth checking for firmware updates. Sometimes the problems you’re trying to solve with a reset have already been fixed in the new version of the software. Check Profile → Mi Band 4 → Check for updates. If an update is available, it’s best to install it before cleaning.
Method 1: Reset via the tracker's own menu
The fastest and most affordable way to bring the Xiaomi Mi Band 4 back to factory settings is to use the device’s built-in menu, which is ideal in situations where the smartphone is unavailable, the app is not working correctly or Bluetooth communication is temporarily lost.
To start, unlock the tracker screen by touching the touch area. Swipe left or right, find the menu item "Additional" (three-dot icon or gear, depending on the firmware version).
- 📱 Tap the screen to activate the sensor.
- 🔄 Fly the menu with swipes until you find the item “Reset».
- ✅ Press and hold the touch button to confirm.
- ⏳ Wait for the Mi logo to signal a reboot.
Once confirmed, the screen will go out, and in a few seconds the tracker will turn on again with the initial language and time settings, and all steps and pulse data not transmitted to the phone will be permanently deleted, which does not require an active Bluetooth connection at the time of reset.
⚠️ Note: When resetting through the bracelet menu, the detachment from the account in the application may not occur automatically. If you change the owner of the device, after the reset, be sure to go to the application and remove the device from the list of associated ones, otherwise the new user will not be able to connect it.
If the problem lies in deep firmware damage, a more radical approach through the application may be required.
Method 2: Uncoupling and cleaning through the Mi Fit application
The second, more software-based method, is the official Mi Fit app (or Zepp Life, which is preferred because it ensures that all background synchronization processes are completed correctly before cleaning, and the algorithm is slightly different and requires a stable Internet connection.
Run the app on your smartphone and make sure the bracelet is connected. Go to the device profile by clicking on your Mi Band 4 image. In the settings menu that opens, look for Unbind. The system will warn you that the data will be deleted from the device but will remain in the cloud.
Once the detachment is confirmed, the tracker will automatically reset. If this does not happen, the bracelet settings menu often has a separate button inside the app, "Reset" or "Factory Reset", and using this menu item will force the device to clear the memory.
The advantage of this method is that the application controls the data transfer process itself, and the application sends a command to clean up only after making sure that all the telemetry is downloaded to Xiaomi servers, which minimizes the risk of losing statistics over the past days.
| Parameter | Reset via the bracelet menu | Resetting through the application |
|---|---|---|
| The need for a smartphone | Not required | I'll be sure. |
| Risk of data loss | High (no synchronization) | Low (autosynchronization) |
| Account untied | No (manually required) | Yes (automatically) |
| Difficulty | Minimum | Medium |
Forced reset when getting stuck
There are situations when the Xiaomi Mi Band 4 interface completely stops responding to touch, and a standard reset through the menu is impossible to perform. The screen may burn, but the swipes do not work, or the device shows a black screen while remaining on.
This process is similar to rebooting your computer with the Reset button. You have to put the bracelet on the charger. Connect to the power source (USB-The computer port or Power Bank often causes the power controller to reset hardware by itself, resulting in a system reboot.
What to do if the bracelet is warm?
If the charging connection doesn't help, the "discharge" method. Leave the tracker to lie down until the battery runs out completely and the device shuts down. Then put it on charge. When turned on after full discharge, the system often resets temporary errors.
There is also a “secret” method of rebooting through the debugging menu, but it is only available on some firmware versions and requires a PC connection. For the average user, the most effective way is to wait for a full discharge or connect to the charger followed by a long hold on the touch button (if it reacts).
⚠️ Warning: Do not attempt to disassemble the body of the Mi Band 4 to retrieve the battery for reset.The device capsule is monolithic, sealed and not intended for maintenance.The autopsy is guaranteed to disrupt the water protection and lead to breakage.
Solving typical problems after resetting
Once you have reset, the device can behave unpredictably for an inexperienced user, most often problems with re-pairing. The phone can "see" the bracelet, but refuse to connect, giving a pairing error.
The first thing to do in this situation is to remove the old device from the Bluetooth list in your smartphone settings. Find in the Mi Band 4 or MI Band 4 list, click on the gear icon or "i" and select "Forget the device" or "Cancel pairing".
- 🔍 Remove the device from the Bluetooth list in the OS settings.
- 📲 In the Mi Fit app, click "Add device».
- 🔋 Make sure the bracelet is near the phone (no more than 1 meter).
- 🔄 If the search does not give results, restart the smartphone.
Another common problem is time desynchronization: After resetting, the Mi Band 4 resets the clock to factory value (usually 2015 or 2016). This is normal. The time will update automatically immediately after a successful connection to the application and initial synchronization.
☑️ Checklist after reset
If the bracelet is not turned on or is constantly restarted in a bootloop after all the manipulations, this may indicate a hardware malfunction or critical damage to the file system, in which case the software methods are powerless, and a service center is required.
Set up the tracker again: basic steps
Once the cleaning process is complete and the device is successfully connected to the smartphone, you will have to set up the initial setup, and you should not ignore this step, since the correct configuration of the Xiaomi Mi Band 4 directly affects the accuracy of measurements and autonomy of operation.
First of all, the app will ask you to choose the interface language and adjust the dial. It is recommended to choose a minimalist dial without complex animations, if you want maximum battery life. Bright and complex wallpaper consumes the screen faster.
Next, you need to configure notifications. Notifications are one of the key functions of the tracker. Go to the "Application Notifications" section and select only those services that are really important (calls, SMS, messengers), the excess notifications will constantly wake the screen and consume energy.
💡
For maximum accuracy in step counting after reset, re-enter your height, weight, and step length in your user profile, which are critical for calorie and distance algorithms.
Be sure to activate the wrist lift function to turn on the screen if you need one. It is also worth checking the pulsemeter settings: it is recommended to set the frequency of measurements "Every minute" or "Automatically" to avoid missing sudden pulse surges during training.
💡
Properly adjusting notifications and pulse measurements after reset can increase the battery life of the Mi Band 4 by up to 20%.
