How to restart the fitness bracelet Xiaomi Mi Band 4: all ways

Xiaomi Mi Band 4

In this article, we’ll look at all the ways to reboot the Mi Band 4, from soft resets to full factory resets, when each method is needed, how to avoid errors, what to do if the bracelet doesn’t respond to commands, and detailed instructions with pictures and videos that will help even beginners.

If your Mi Band 4 is not synced with the Mi Fit app, doesn't show notifications or just "gluts", don't rush to bring it to the service. 90% of the time, the problem is solved by rebooting. But it's important to do it right - otherwise you can make things worse.

When do I need to restart the Xiaomi Mi Band 4 fitness bracelet?

Not every problem requires drastic measures. Before resetting, check if your Mi Band 4 really needs a reboot. Here are the typical symptoms that a reset helps:

• 📱 Bracelet does not sync with the smartphone (error "I failed to connect")
• ⏳ The screen hangs on the Mi logo or does not respond to touches
• 🔋 Battery discharges quickly (less than 2 days of operation)
• 📊 Pedometer or pulsemeter data are reset or not stored
• 🔔 No notifications of calls and messages are received
• 🔄 After updating the firmware bracelet is not working properly

If you see at least one of these signs, try a mild reset (Section 3). In difficult cases, such as when the bracelet is not turned on at all, a hard reset will be required (Section 4).

Important! Don't confuse a restart with a firmware update. A restart doesn't delete data, and a factory reset wipes all the information off the bracelet.

Preparing for the restart: what to do in advance

Before you start resetting, follow a few simple steps to avoid data loss and other issues:

1. Sync your data with Mi Fit or Zepp Life, open the app, wait until the sync is complete, and it will store your activity history, your sleep history, and other metrics.
2. Check the battery. It should be at least 20%. If the bracelet is discharged, plug it into the 10-15 minute charge.
3. Disconnect the bracelet from the smartphone in the Bluetooth settings. This will prevent conflicts when connecting after rebooting.
4. Remember the current settings: alarm clocks, notifications, screen order, and you'll have to reset them once you reset them.

If the bracelet does not respond to touch and does not sync, skip step 1 and immediately proceed to a hard reset (section 4).

Method 1: Soft reboot (without data loss)

This is the safest method, and it works 70 percent of the time, and the Soft Reset doesn't delete user data, it just restarts the bracelet system.

Instructions:

1. Connect the bracelet to the charger (even if the battery is charged).
2. Press and hold the touch button under the screen for 10-15 seconds.
3. Wait for the Mi logo to appear on the screen, then release the button.
4. The bracelet will reset automatically. It'll take about 30 seconds.

If the screen does not respond to the button holding, try an alternative method:

1. Open the Mi Fit application → Profile → Your bracelet → “Disable the device”.


2. Wait 1 minute.




3. Reconnect the bracelet via Bluetooth.

Note: After a soft reboot, all settings (alarm clocks, notifications) will be saved, but data synchronization may be required.

💡

If the bracelet does not respond to the button holding, try holding it. 20-25 Sometimes the device takes longer to react.

Method 2: Hard reset (full reset to factory settings)

This method is used when a soft reboot doesn't work or the bracelet doesn't turn on at all.

• 📅 Activity history (steps, sleep, training)
• ⏰ Settings for alarm clocks
• 🔔 Configuration of notifications
• 🔐 Unblock password (if set)

Hard-dumping instructions:

1. Disconnect the bracelet from the charger (if connected).
2. Press and hold the touch button under the screen.
3. Without releasing the button, connect the bracelet to the charging.
4. Hold the button for another 20-30 seconds until the Reset or Mi logo with the progress bar appears on the screen.
5. Release the button and wait until the process is completed (about 1-2 minutes).

Once reset, the bracelet will automatically reboot, and you will need to reconnect it to the Mi Fit app and adjust all settings.

Solving common errors after restart

Sometimes, after a reset, the Mi Band 4 behaves incorrectly, and here are the most common problems and solutions:

⚠️ If the bracelet fails to turn on after a hard reset or shows an Error 5 error, this may indicate a hardware malfunction.

How to update the firmware after restarting

After reset, it is recommended to update the firmware Mi Band 4 to the latest version, which will fix possible bugs and improve stability.

Step-by-step:

1. Connect the bracelet to charging and make sure the charge level is not below 50%.
2. Open the Mi Fit or Zepp Life app.
3. Go to Profile → Your Bracelet → Update firmware.
4. If a new version is available, click Update.
5. Do not disconnect the bracelet from charging and do not close the application until the process is complete (this will take 5-10 minutes).

Important: During the upgrade, the bracelet will display progress bar. If the process is interrupted, the bracelet may fail and require repair.

If the update is hanging:

• 🔄 Reload the bracelet (Section 3).
• 📱 Reinstall the Mi Fit app.
• 🔌 Try another charger.

💡

Updating your firmware through the official app is the only safe way. Don't use third-party firmware, it can brick the bracelet.

What to do if the bracelet does not respond to reset?

If the Mi Band 4 doesn’t turn on, respond to a button, and reset, try the following methods:

Verification of charging:

• 🔌 Use the original charger.
• 🧼 Clean the bracelet contacts and charging with a cotton swab soaked in alcohol.
• ⏱️ Connect the bracelet to the charger on 2-3 hour (even if there is no indication of charging).

Alternative method of discharge:

1. Connect the bracelet to the charger.
2. Press the touch button 10 times in a row at 1 second interval.
3. For the 11th time, hold the 10 seconds button.

3. Check for hardware damage:

• 🔍 Check the bracelet for cracks or bloating (a sign of battery damage).
• 💧 Make sure there is no moisture inside (even if the bracelet is waterproof, the contacts may oxidize).

⚠️ Attention, if the bracelet fell from a height, got wet or was subjected to mechanical stress, the reset may not help.
