The Xiaomi Mi Smart Band 4 fitness bracelet remains one of the most popular wearables thanks to its combination of functionality, design and affordable price. However, even such a reliable device sometimes has problems turning on β especially after prolonged downtime, discharging or resetting. If your bracelet does not respond to presses, does not show the screen or behaves unstable, do not rush to carry it to the service center.
In 90% of cases, the problem is solved independently in 5-10 minutes. In this article, we will discuss all possible ways to enable Xiaomi Smart Band 4, from basic to advanced, and explain why the bracelet may not turn on and how to avoid this in the future.
Before you start, make sure you have a charging cable (original or compatible), a smartphone with Mi Fit app (at least 4.6.0) and a little patience. Next are step-by-step instructions with explanations for each case.
1. Standard on: button and sensor
If the Xiaomi Smart Band 4 bracelet is completely discharged or has been manually turned off, it can be turned on in the standard way.
- Connect the bracelet to charge for 10-15 minutes. Even if the indicator does not burn, this does not mean that charging is not going; sometimes it takes time to activate the power controller.
- Press and hold the touch button (the area under the screen) for 5-7 seconds.
- If the screen doesnβt respond, try touching the screen β sometimes the bracelet turns on after just touching.
If the bracelet doesn't turn on after this, move on to the next method. Importantly, don't press the button for longer than 10 seconds, which can lead to a forced reboot, which in rare cases exacerbates the problem.
2. Forced reset (Hard Reset)
If the bracelet is getting stuck, doesn't respond to touch, or shows a black screen, but it vibrates when you connect to a charge, forced rebooting will help, a technique that resets temporary system errors without deleting data.
Instructions:
- Connect the bracelet to the charger (required!).
- Press the touch button for 15-20 seconds until you feel a double vibration.
- Release the button β the bracelet should reboot and show the Mi logo.
If the reboot didnβt work, try repeating the procedure 2-3 times at 1 minute intervals, sometimes the system needs to be βwarmed upβ after a deep discharge.
Connect the bracelet to charging
Make sure the cable is in good working order.
Press the button for 15+ seconds
Wait for the double vibration

β οΈ Warning: Don't confuse Hard Reset with Factory Reset. Forced reset doesn't delete data, whereas factory reset wipes all the information off the bracelet.
Initiation via charger
One of the little-known ways to reanimate Xiaomi Smart Band 4 is to use an alternative power source. If the original cable doesn't work, try:
- π Connect the bracelet to a power bank or other USB-Sometimes the voltage in the socket is insufficient.
- π Use charging from another Xiaomi device (e.g., Mi Band 3 or Mi Band 5) if the connector matches.
- β‘ Place the bracelet on charge for 30 to 60 minutes, even if the indicator is not on".
If the bracelet still does not respond, check the charging contacts for oxidation or contamination. Gently wipe them with an alcohol napkin or a soft brush.
| Symptoms. | Possible cause | Decision |
|---|---|---|
| The charging indicator is not on. | Faulty cable or power supply | Try another cable/charging |
| The bracelet vibrates, but does not turn on | Firmware getting stuck | Hard Reset (method 2) |
| The screen flashes and goes out. | Unstable nutrition | Connect to a stable source (not USB 3.0!) |
| The bracelet warms up when charging | Short circuit or bloated battery | Turn it off immediately, contact the service. |
4. Factory Reset (Factory Reset)
If previous methods have failed, the last option before you go to the service is a complete reset, which removes all data from the wristband, including pairs with your phone, settings and statistics, and only use it as a last resort!
How to make Factory Reset:
- Connect the bracelet to the charger.
- Press and hold the touch button for 10 seconds until the menu appears.
- Release the button and quickly press it 5 times in a row - this will activate the reset mode.
- Confirm the action by touching the screen (a tick will appear).
Once reset, the bracelet will reboot and return to factory settings, and you'll need to re-connect it to the Mi Fit app and adjust the settings.
What to do if the reset does not help?
β οΈ Note: Do not try to disassemble the bracelet yourself if you do not have experience with microelectronics. Xiaomi Smart Band 4 is assembled on glue and latches, and it is very easy to damage the screen plume or battery when you open it neatly.
5.Verification through the Mi Fit app
Sometimes the bracelet may be turned on but not displayed on the screen (for example, due to a failure of the display driver).
- Open Mi Fit on your smartphone and go to Profile β Mi Smart Band 4.
- If the bracelet is connected, you will see its status (charge level, firmware version).
- Press Disable the device, then pair again.
- If the bracelet doesnβt appear in the list, try updating the firmware through the app menu.
If the app doesn't see the bracelet, but it vibrates when you connect to the charger, the problem may be in the Bluetooth module of the gadget.
- π± Reboot your smartphone.
- π Turn off and turn on Bluetooth again.
- π² Remove the bracelet from the list of conjugated devices in the phone settings.

If the bracelet connects to Mi Fit, but the screen remains black, try updating the firmware through the app. To do this, go to Profile β Mi Smart Band 4 β Firmware update. Even if the version seems relevant, forced updating sometimes solves problems with the display.
6. Diagnosis of malfunctions: when to contact the service
If none of these methods worked, the bracelet probably has a hardware breakdown, and here are some signs you should consult a specialist.
- π₯ The bracelet warms up when charging or in normal mode.
- π§ On the screen or under the case, traces of corrosion are visible (infection of moisture).
- β‘ The charging indicator flashes red and goes out.
- π The bracelet emits a squeak or crackle when connected to charging.
- π The battery will run out in a few hours (even after full charge).
The cost of repairing Xiaomi Smart Band 4 in service centers usually does not exceed 1000-1500 rubles (replacement of the battery or plume).However, if the gadget is older than 2-3 years, it is economically more feasible to consider buying a new model (for example, Mi Band 7 or Mi Band 8).
