The situation when Xiaomi Mi Band 4 stops responding to touches after forced reset often puts the owner in a baffle.It seems that the device has failed, however, in most cases it is the normal behavior of the security system or a temporary failure of the software. the gadget goes into deep waiting mode for energy saving, waiting for command from the conjugated smartphone.
Understanding the logic of the tracker helps avoid panic and missteps that can make the problem worse. Once reset, the fitness bracelet software shell reboots and takes time to initialize the internal modules. If you don't see the familiar welcome logo, it doesn't mean the screen or battery breaks.
In this guide, we will discuss in detail the device activation algorithms, forced reboot methods and methods for correcting common errors. It is important to act consistently, checking each stage of connection and charging to return the tracker to full life.
Reasons for the lack of reaction after resetting
The first thing to do is to understand why the Mi Band 4 isn't behaving as expected, and often it's not the reset itself, but the battery drain when it's rebooted or the software conflict, and when you initiate a factory reset, the device consumes more power to clean up the memory.
If the charge was low at that point, the bracelet could simply turn off and now it does not turn on in the standard way, and it is worth considering that after the reset, the binding to the account disappears, and the device goes into a waiting mode for new synchronization.
- 🔋 Full discharge of the battery during system restart.
- 📱 No active Bluetooth connection with Mi Fit or Zepp Life.
- ❄️ Software freeze of the power management module.
- 🔌 Oxidation of contacts on the charger, preventing the supply of current.
In some cases, the problem lies in the malfunction of the app itself on the phone. The app cache may contain old profile data that conflicts with the "clean" state of the bracelet, so it is important not only to monitor the status of the tracker, but also to check the settings of the smartphone.
Primary activation and charging of the device
The most reliable way to wake up Xiaomi Mi Band 4 is to connect to a power source. Even if the indicator does not light up immediately, the current can start to flow into the battery in a few minutes. Use only the original cable or certified counterpart, as the voltage must be strictly 5V.
Insert the tracker into the charger and connect it to USB-Note the location of the contacts: they should fit tightly to the metal pads on the bottom of the capsule.
☑️ Connection check
If the screen remains black, don't be in a hurry to turn off the device. Leave it on charge for at least 15-20 minutes. In some cases, the deep discharge protection system blocks the on-set to dial the minimum charge level.
💡
Wipe the contacts on the bracelet and charge with an alcohol napkin before connecting - oxides often interfere with the passage of current.
After the device gets enough power, the Mi logo should appear on the screen. If this does not happen, try to slightly tap the touch area or swipe your finger on the screen up and down.
Forced system reboot
When standard methods fail, a more stringent intervention is required in the tracker's operating system. Forced reboot allows static electricity to be discharged and the power controller to restart. There is a special combination of actions for the Mi Band 4.
You need to connect the bracelet to the charger. While charging, you need to touch the touch area and hold your finger for 10-15 seconds. In some firmware, multiple quick pressing on the sensor (5-7 times in a row helps.)
⚠️ Warning: Do not use sharp objects to press on the screen, so as not to damage the matrix or protective glass.
If the screen blinks or the image appears, release the sensor immediately. The device will start the boot procedure. In the process of restoring system files, the screen can go out and light up again, which is normal behavior.
In rare cases, cyclic charging helps, so you plug the bracelet into a 10 second charge, then turn it off for 5 seconds, and reconnect it, and repeat it 3-4 times, which helps to rock the chemical processes in the battery.
The Mi Fit/Zepp Life app is available.
Once the screen is successfully turned on, the Xiaomi Mi Band 4 will require re-assignment.Setting reset deletes all data about the previous user.You'll need the Zepp Life app (formerly Mi Fit) or Mi Fitness on your smartphone.
Open the app and go to the profile section. Click Add Device and select your bracelet from the list. It's important that the smartphone has Bluetooth and GPS enabled, as Android requires this to find devices.
| Phase | Action. | Expected output |
|---|---|---|
| 1 | Searching device | The list includes "Mi Band 4". |
| 2 | Request for pairing | On the screen of the bracelet vibrates the icon |
| 3 | Confirmation | Touch the sensor on the bracelet |
| 4 | Synchronization | Downloading data and updating time |
If the app says "Device already added," you need to remove it from the list in your profile first. Click on the bracelet name, scroll down and select "Unplug." Only then you can start the search again.
What to do if the bracelet is not in place?
When you pair, you'll see a confirmation request on the tracker screen, which is protection against random connection of other devices, and you'll touch the touch button, and the data will start to be transmitted.
Solving Connection Problems
Sometimes it's successful, but it's impossible to synchronize data, which may be due to the limitations of the smartphone operating system, especially on Android 11, 12 and later.
Check the permissions for Zepp Life or Mi Fitness. Make sure the app is allowed to run in the background, access Bluetooth and location. Without these rights, stable communication with the fitness tracker is impossible.
- 📍 Turn on geolocation (GPS) time-search.
- 📡 Restart the Bluetooth module on your smartphone (turn off/on).
- 📲 Clear the app cache in the phone settings.
- 🔄 Remove the device from the list of conjugated in Bluetooth settings.
It is also worth checking the firmware version of the app itself. Older versions may not work properly with new firmware bracelet updates. Update the app via Google Play or App Store to the latest available version.
If nothing helps, try connecting the bracelet to another smartphone, which will allow you to understand whether the problem lies in the Xiaomi device itself or in the settings of your main phone.
Specificity of the touch screen
Users often forget that the Mi Band 4 is equipped with a new version. OLED-It's a touch-controlled display, but it doesn't have physical buttons, and all navigation is done by swipes and touches, and once it's reset, the sensor's sensitivity may temporarily decrease.
To activate the screen, it is usually enough to raise the wrist or touch the surface. If the screen goes out too quickly, check the settings in the application: there you can set the backlight time of 5 seconds, 10 seconds or 15 seconds.
⚠️ Warning: The screen may not respond to touch with wet hands or gloves.Wash the surface with a dry cloth before use.
And in rare cases, you see a dead zone effect on the edges of the screen, which is a design feature of the model, and try to touch the center of the display to activate it.
💡
If the sensor does not respond even after restarting, it may be necessary to calibrate through the engineering menu or replace the module.
