Why Mi Band 4 Bracelet Doesn't Turn On After Resetting and What to Do
Resetting the settings on Xiaomi Mi Band 4 is a standard procedure when selling a device, fixing bugs or preparing for a new firmware, but after that, many users face a problem: the bracelet stops responding to pressing, does not turn on or sync with the smartphone, 80% of the time it is due not to a breakage, but to the wrong sequence of actions on the first launch.
In this article, you will find step-by-step instructions on how to turn on the Mi Band 4 after reset, what buttons to press, how to connect it to the phone and what to do if the screen remains black, we will also analyze typical errors (for example, endless loading or no vibration) and give tips for restoring health without contacting the service.
If your bracelet is dead before reset or has been bugged, the algorithm will be different – read about this in the section “Recovery after critical failures.” First, check if your situation is one of these:
- 🔋 The bracelet vibrates when charging is connected, but the screen does not light up.
- 📱 Mi Fit (or Zepp Life) app doesn't find the device.
- 🔄 The Mi logo appears on the screen, but no further downloads.
- 🔌 Charging is going, but after disconnecting the bracelet immediately turns off.
Step 1: Check the battery before turning on
The most common reason for not turning on the Mi Band 4 after reset is a discharged battery. Even if the bracelet showed 20-30% charge before reset, the procedure for cleaning the memory and restarting the system can completely exhaust the energy reserve.
How to check if the charge is going:
- 🔌 Connect the bracelet to the original cable (or a certified USB-Type A).
- 🔋 The screen should show a battery icon with lightning (if the charge is going) or a red indicator (critically low charge).
- 📌 If the screen is not responding, try to easily tap the case near the connector - sometimes the contacts oxidize.
⚠️ Note: Do not use chargers with output current more 1A, it could damage the power controller of the bracelet. USB-port of the computer or adapter 5V/0.5A.
If after 30 minutes of charging the screen does not catch fire:
- Unplug the cable and wait 10 seconds.
- Reconnect – sometimes the controller’s “cold start” is triggered.
- Try another cable or power supply.
Step 2: Forced reset of the bracelet
If the bracelet is charged but does not respond to touch, try to force it to restart.
- Disconnect the device from charging.
- Press and hold the touch button (the area under the screen) for 10-15 seconds.
- Wait for the vibrations – this is a signal to start a reset.
After the reboot, the Mi logo should appear on the screen, followed by the language selection menu.
- 🔄 Repeat the procedure 2-3 times with an interval of 30 seconds.
- 🔋 Connect the bracelet to charging for 5 minutes, then reboot.
- 📱 Make sure your phone is enabled with Bluetooth and geodata permission (needed for synchronization).

Step 3: Connect to the phone via Mi Fit/Zepp Life
After a successful reboot, the Mi Band 4 bracelet will be ready to be tuned.
- Download the latest version of the application: 📱 Mi Fit (for old firmware) – Google Play / App Store. 📱 Zepp Life (recommended for new firmware) – Google Play / App Store.
Xiaomi
Add the device → Bracelet → Mi Smart Band 4
Follow the instructions on the screen (allow access to notifications, contacts, etc.).
If the app does not find the bracelet:
| Problem. | Decision |
|---|---|
| The bracelet is not displayed in the list | Reboot your bracelet and phone, check Bluetooth |
| The "failed to connect" error | Remove the bracelet from the Bluetooth device list in your phone settings and try again |
| The application freezes at the synchronization stage | Update the application and firmware of the bracelet through Settings → Software Update |
| The bracelet is connected, but the data is not updated | Reset the app cache (Phone Settings → Apps → Mi Fit/Zepp → Memory → Clear the cache) |
⚠️ Note: If you use custom firmware (such as Notify & Fitness), make a full reset via the bracelet menu before connecting to the official app: → Reset → Confirm. Otherwise, data conflicts may occur.
Step 4: Setup the bracelet after resetting
After successful connection, you need to configure the main parameters:
- Language selection: Scroll down to the desired language (Russian is usually marked RUS).
- Account Connection: Enter your Xiaomi account details (if you haven’t done so in the app).
- Data Synchronization: Wait until the synchronization is complete (it can take up to 5 minutes).
- Set up notifications: In the app, allow access to: 📞 Call and SMS. 📧 Notifications from messengers (WhatsApp, Telegram, etc.). 📅 Calendar and alarm clocks.
If notifications are not displayed on the bracelet after synchronization, check the power saving settings on the phone: some manufacturers (for example, Xiaomi, Huawei) block the background work of Mi Fit by default.
💡
To ensure that notifications come without delay, add Mi Fit or Zepp Life to the battery optimization exception list. On Xiaomi, this is done in Settings → Battery → Battery Optimization → All Apps → Select Mi Fit → No Limits.
Step 5: Recovery from Critical Failures
If the Mi Band 4 bracelet does not turn on even after charging and restarting, there may have been a software failure (for example, an interrupted firmware update or deep discharge), in which case the disaster recovery will help:
- Connect the bracelet to charging and wait for the indicator to appear (even if the screen does not light up).
- Hold the touch button for 20-30 seconds until double vibration is the signal to reset to factory settings.
- If the bracelet is not vibrating, try an alternative method: 1. Turn off charging. 2. Press and hold the button. 3. Without releasing the button, plug the charging. 4. Hold for another 10 seconds.

Step 6: Update the firmware after resetting
After resetting, it is recommended to update the bracelet firmware to the latest version, this will eliminate possible bugs and improve stability.
- Open the Mi Fit or Zepp Life app.
Important nuances:
- ⏳ Do not interrupt the process!Switching off the bracelet or phone during the upgrade can lead to "bricking" (complete inoperability).
💡
Updating your firmware through the official app is the safest way, as files are tested for compatibility with your bracelet model. Avoid manual firmware through third-party utilities if you don't understand the technical details.
Frequent mistakes and their solutions
Even after successful inclusion, users face problems, and here are the most common ways to fix them:
| Mistake. | Reason. | Decision |
|---|---|---|
| Bracelet discharges quickly | Background processes, outdated firmware | Update the software, disable unnecessary notifications, reset statistics |
| Data is not synchronized | App cache failure | Clear the Mi Fit cache and reboot the phone |
| The screen doesn't respond to touch. | Sensor contamination, calibration failure | Wash the screen with an alcohol napkin, perform a reset |
| The bracelet doesn't vibrate. | Vibration turned off in the settings | Check the settings → Vibration in the application |
| The wrong time. | Failure to sync with the phone | Reconnect the bracelet to the app |
If none of these methods worked, try contacting Xiaomi support via the official website or contact the service center. 90% of the time, the problems are solved software, but if the bracelet is physically damaged (for example, after a fall or water hit), repair may be necessary.
