When a fitness tracker suddenly loses all the data they have accumulated or resets to factory settings, it is always taken by surprise. Users often find the Xiaomi Mi Band 4 no longer synced, time shows the wrong, and the history of steps disappears. This can happen for all kinds of reasons, from banal battery discharge to software failures in the Mi Fit or Zepp Life app.
Don't panic early, because most of the time, the problem is solved without going to the service center. Data resets are often a system defense or a result of loss of communication between the wristband and the smartphone. It's important to understand that the basic information is usually stored in the cloud or on the phone itself, not just in the device's memory.
In this article, we will discuss in detail why your gadget could have hard reset, how to restore synchronization correctly, and what to do if the bracelet went into pairing mode for no apparent reason. We will consider both software solutions and the physical aspects of wearable electronics.
Main causes of data loss and reset
The first thing to analyze is the state of charge. If the device's battery was completely discharged for a long time, the power controller could initiate a forced reset to preserve the integrity of the file system. In the Xiaomi Mi Band 4, there is a small battery, and deep discharge is a common cause of loss of temporary settings.
The second common factor is software conflict: updating the firmware through the Mi Fit application sometimes goes wrong, especially if the Internet connection is interrupted at this point or the smartphone has gone into sleep mode. Synchronization error leads to the fact that the tracker “forgets” the binding to the account and returns to factory parameters.
⚠️ Warning: If you have manually reset your bracelet menu settings hoping to fix the freeze, remember that this action irreversibly removes a local activity history that has not yet been transmitted to your phone.
Although the Mi Band 4 has protection from moisture and dust, strong shocks or static electricity can cause short-term closure of contacts inside the module, which is perceived by the system as a signal to reset or reset.
Checking the synchronization status in the annex
Before you do complex manipulations, you need to make sure the connection status. Open the Zepp Life app (formerly Mi Fit) on your smartphone. If the bracelet is displayed in the list of devices but the data is not updated, try clicking on the profile icon and select Check Updates. Sometimes the system will suggest restoring the backup.
It is important to check whether Bluetooth is active and whether the restriction of background work for the application is worth it. Modern versions of Android aggressively save charge by killing the processes of the tracker. Go to the phone settings, find the Applications section, select Zepp Life and set the No Limits mode in Battery.
- 📱 Make sure that in Bluetooth settings, the Mi Band 4 device does not appear as “Connected” in the system menu, but is managed only through the application.
- 🔄 Try to click the “Sync” button in the main window of the program and wait for the current time to appear.
- 🔐 Check if your Mi Account is logged in, as the history is stored there.
If the app sees the bracelet but says "Device not found" or requires repairing, it means that the connection was indeed severed, in which case the data for the period of no communication may not be saved, but the old records should remain in the cloud.
💡
Before re-pairing, be sure to take a screenshot of the current data in the app if there is any important stats left there that you are afraid to lose.
Step-by-step instructions for reconnecting the bracelet
If the reset has already occurred, the only right solution is to completely re-assign the device, which takes no more than five minutes, but requires care. First, remove the device from the Bluetooth list in the phone settings to avoid addressing conflicts.
Then open the Zepp Life app, go to profile and click Delete device (if it's listed there). Then search for new devices. Mi Bend 4 should appear in the list of available gadgets. Click on it to begin the pairing procedure.
