Resetting Mi Band 4: A Complete Recovery Guide

When Xiaomi Mi Band 4 suddenly resets to factory settings, it can take anyone by surprise: notifications stop coming, activity statistics are zeroed, and the device begins to behave as if it has just been unpacked, most often after a failed firmware update or loss of communication with the smartphone, but panic early.

Restoring the health of the gadget is not a difficult process if you act consistently and understand the logic of the Mi Fit system. In this article, we will analyze all possible scenarios, from simple re-binding to complete reset, and bring your tracker back to life.

Reasons for resetting the tracker configuration

Before we can reanimate the device, we need to understand what caused the problem: data synchronization could be interrupted at a critical moment, or the Bluetooth module of the smartphone temporarily lost connection to the bracelet, sometimes the culprit is the application itself, which could update and “forget” the old pairing parameters.

Another common reason is the critically low battery charge: If the battery was depleted during a workout or upgrade recording, the device could be forced to restart by resetting temporary configuration files, and the human factor should be considered: a random long press on the touch button could activate a hidden reset function.

The software errors of the bracelet operating system itself should not be excluded, the firmware may contain bugs that manifest themselves under certain operating conditions. If the failure occurred immediately after the installation of the new version of the software, there is a high probability of file conflict.

⚠️ Note: If the bracelet resets continually, even after re-binding, this may indicate a physical malfunction of the memory module or battery wear.

Understanding the cause will help avoid a repeat of the situation in the future, for example, if it was a question of unstable Bluetooth, it is worth checking the settings of the phone's energy saving.

Primary diagnosis and connection verification

The first step should always be basic diagnostics. Make sure that Bluetooth on your smartphone is on and running correctly. Try to find the device in the list of gadgets available for connection. If the Mi Band 4 is displayed but not connected, it may still be hanging in the phone's memory as an active device.

Check the bracelet status in your phone's system settings. Go to Settings → Bluetooth → My devices (name may vary depending on your smartphone model). If you see your tracker there, click on the gear or information icon and select "Forget the device" or "Cancel pairing."

📊 How often do you have a Mi Band failure?

Rarely, once every six months.

Constantly after updates

Only when the battery is discharged.

Never encountered it.

Once you've turned off the phone, restart the phone itself, clearing the Bluetooth cache and eliminating any software conflicts, and only after you've turned the phone on fully can you move on to the bracelet itself.

Instructions for re-binding through Mi Fit

The main tool for managing the tracker is the Mi Fit app (or Zepp Life), and if the bracelet resets, it will likely need to be removed from the profile and added again. Don't worry, your historical data, if it was previously synced, will be stored in the cloud.

Open the app and go to the device profile. Find the "Untie" or "Unbind" button. Confirm the action. Now the bracelet screen should show a message about readiness for (conjugation). If the screen is black, tap the sensor to wake up.

Now, click Add Device in the app and select Mi Band 4 from the list. The tracker screen will show a vibration and ask you to confirm pairing. Press the touch button. The process takes no more than 30 seconds.

Once the connection is successful, automatic synchronization will begin, at which point the current firmware version can be installed on the bracelet, do not interrupt the process and keep the devices nearby.

⚠️ Note: During synchronization and firmware updates, it is strictly not recommended to open other heavy applications on a smartphone, so as not to overload the Bluetooth channel.

Full reset to factory settings

If a simple re-binding didn’t help and the glitches persisted, a hard reset would be required, which would put the Xiaomi Mi Band 4 back out of the box by removing all local data and settings, a last resort, but often the only one that works.

To reset the bracelet itself (if available): swipe across the screen to the More section. Find System or gear icon. Select Reset from the options list and confirm the action with a long press.

Alternatively, through an app, the device profile in Mi Fit sometimes has a "Factory Reset" option. If the bracelet menu is not available due to freezing, you can try to discharge the device completely before turning off and then put it on charge. When you turn on at low charge, some versions of the software allow you to reset.

Once reset, the device will require re-tuning the language, time and activity goals, which is standard initialization.

Recovery of activity and health data

The most painful issue for users is data loss, and it's important to understand how the storage architecture in Xiaomi's ecosystem works, and locally, the bracelet only stores temporary buffer information from the last days, if there's no synchronization.

All the basic metrics — steps, pulse, sleep, exercise — are stored on the company’s servers immediately after successful synchronization with the phone, so when you link a “new” bracelet to your Mi Account, the app will pull the entire story from the cloud.

What to do if the data is not restored?

If the story is empty after linking, check if you are logged in to the same account. It is also possible that the data did not have time to load due to poor Internet. Try pulling the list down in the application for forced updates.> However, if you do not sync the bracelet for several weeks, the data for this period will, alas, be lost irrevocably, since the overflowing memory buffer of the tracker is overwritten with new readings. To minimize the risks, you should set up automatic synchronization. Go to the profile settings in the application and make sure that it is ticked "Syncronize the "Sync for this period, this period, the Mi Band will be allowed to reset the application returns, so that after the application is allowed to the list of the application, after the launch of the notification 4, it will be resetting the application. "After the new application, it will be resetting the new application will be resetting the notifications will be sent to the new application. Go to Profile. → Mi Band 4 → Notification settings. Here you'll see a list of all the apps installed on your smartphone. Activate the switches in front of the ones you want: WhatsApp, Telegram, calls, SMS. Without this setting, the bracelet will only vibrate when the call is in, ignoring the messages. It's also worth reconfiguring the dial. Go to "Digitals", select your favorite style and click "Install." Custom dials can be downloaded from the gallery, creating a unique design. Don't forget to check your wrist lift settings. If the screen doesn't light up when you raise your hand, increase sensitivity or turn off the "Do Not Disturb" mode, which could have activated automatically. ⚠️ Warning: After resetting the alarm clocks on the bracelet are also removed. be sure to reset them through the app, as the standalone alarm clock works even without a phone. To prevent a reset from happening again, you should follow a few simple rules of operation: Regularly update the Mi Fit app and the tracker itself. Developers are constantly releasing patches that fix stability errors. Keep an eye on the battery, though, the lithium polymer battery in the Mi Band. 4 Keeps the charge long, deep discharge is bad for electronics. Try to put the device on charge when there is a leftover 10-15%. 💡Stability of Mi Band operation 4 on 90% It depends on the quality of the Bluetooth connection and the version of the intermediary application on the smartphone. Avoid using third-party, informal applications to control the bracelet. They may not work properly with data protocols, causing desynchronization and subsequent failures. If you plan to change your phone, remember to unplug the device correctly in the app before switching to a new gadget. This will preserve the integrity of your account database.
