Xiaomi’s smart activity trackers have proven to be reliable companions for sports and everyday life, but even the most stable technique sometimes requires user intervention.If your Mi Band 4 has stopped responding to touch, doesn’t sync with your smartphone, or you just decide to sell the device, it becomes necessary to perform a complete reset.
Many owners mistakenly believe that it requires complex manipulation of the code or disassembly of the case. In fact, the MIUI architecture for wearables allows you to solve most software conflicts with regular means. It is important to understand the difference between a simple restart and a complete reset to factory settings, because the consequences of these actions are completely different.
In this article, we will take a look at all the available methods for restoring tracker performance. We will look at software methods through the official application, manual methods for cases when the screen does not respond, and answer questions about data loss. Make sure that the bracelet is charged at least 50% before starting any operations to avoid critical discharge in the process.
When a complete tracker reset is required
Before you start taking drastic measures, it’s worth analyzing the current state of your device. Often users are looking for a way to reset the Xiaomi 4 bracelet when the problem is solved with milder methods.
One of the most common reasons is a change of ownership: If you plan to sell a gadget or give it away, deleting your personal data is a security issue; when paired, a new user will have access to your sleep history, pulse, and routes if you don't clean it up, and a reset is necessary when you sell the device to a store or service center.
Another case is critical software errors, where if the tracker is stuck on the logo, does not respond to touches of the sensor or stops displaying notifications, this may indicate damage to system files, in which case a reboot may not help, and a complete memory cleanup is required.
It’s worth noting that periodic Bluetooth failures may also require intervention. If a device is permanently losing touch with a smartphone for no apparent reason, resetting connection settings often resolves driver conflict, especially after a phone operating system update.
Preparation of the device for the procedure
An unprepared reset can result in the loss of important statistics you have been collecting for months.Before you click the cleanup button, you need to make sure your activity history is stored in the cloud.The Zepp Life app (formerly Mi Fit) or Mi Fitness automatically syncs the data, but it's best to check this manually.
Open the app on your smartphone and go to the home screen. Pull the list down for forced synchronization. Make sure the steps, heart rate and sleep indicators are updated to the current time. If the cloud icon is on or spinning, wait until the process is complete. This ensures that your activity profile is not lost.
- 🔋 Make sure that the battery is at least 50-60%, So that the device does not turn off at the most inopportune moment.
- 📱 Keep your smartphone with the installed app next to the bracelet at a distance of no more than 1 meter.
- 📶 Check the stability of the Internet connection on your phone for successful synchronization of the data archive.
- 🔐 Remember or write down. PIN-the drop screen unlock code if it was installed (although it will still be deleted when reset).
It is also recommended to check for firmware updates before reset. Sometimes the problem you are trying to solve with the reset has already been fixed in the new version of the software. Go to the device profile in the application and select "Verify Updates." If a new version is available, install it - this can fix the bugs without losing data.
💡
Before resetting, take screenshots of important dial settings or activity targets to quickly restore them after resetting.
Method 1: Reset via Zepp Life
The safest and most correct way to return Xiaomi Mi Band 4 to factory settings is to use the official mobile application.This method ensures the correct removal of all pairing profiles and clearing the cache without risking damage to the system partition of the device.
Run the Zepp Life app on your smartphone. On the home screen at the bottom of the interface, select the Profile tab. On the My Devices list, find your tracker (usually labeled Mi Band 4) and click on it. The device management page will open.
Scroll down to the end of the menu, and you'll find "Untie" or "Unbind" (depending on the interface language), click on it, the system will issue a warning that all data will be removed from the bracelet, confirm the action by entering a confirmation code if necessary, and then the tracker vibrates and reboots to its original state.
☑️ Checklist of proper untiing
It is important to understand that after this procedure, the bracelet will become a “clean slate”. All accumulated steps that were not synchronized before the button was pressed will be lost. However, if you followed the recommendations from the previous section, your statistics are already stored in your Xiaomi account.
Method 2: Remove via Bluetooth settings
Sometimes the application is unavailable or not working properly, and in such cases you can try to break the connection through the system settings of the smartphone operating system, which is less preferable, since it does not always initiate a complete data reset on the tracker itself, but often helps solve connection problems.
Go to your phone's settings and select the Bluetooth section. From the list of available and paired devices, find the Mi Band 4 entry. Click on the gear icon or information icon next to the device name. From the menu that opens, select "Forget the device" or "Cancel pairing."
⚠️ Note: This method removes encryption keys only from the phone side. The data on the bracelet itself may remain. Complete deletion of information will still require the use of the application or reset via the tracker menu itself (if the model supports the device).
After removal from the Bluetooth list, you need to restart the smartphone. This will clear the cache of Bluetooth services and allow the system to re-discover the device when you try to re-pair. If the bracelet continues to glow in the list of devices, try turning off and turn on the Bluetooth module on the phone.
Method 3: Hardware Reset and Device Menu
Unlike a full-fledged smartwatch, the Mi Band 4 doesn't have a hidden button combination to enter Recovery mode or factory reset through physical impact. The touchpad is the only control. However, if the device is getting stuck, there is a method of forced reboot.
If the screen doesn't respond to touch, plug the tracker into the charger. 90 percent of the time, connecting to the power source triggers a restart. If that doesn't work, you can try the zero-discharge method. Leave the device to lie down until the battery is completely exhausted, then charge it to the end. This often eliminates software wedges.
In the menu of the bracelet itself (if it responds), you can find the item "Reset" or "Reset" in the "System" or "Advanced" section. The path may vary depending on the firmware version. Usually this: Additional → System settings → Reset. Pressing is confirmed by long-term retention of the touch zone.
