How to reboot Xiaomi Mi Band 4 if it freezes: 5 working ways

Why Mi Band 4 Can Hang Up and When You Need a Reboot

The Xiaomi Mi Band 4 fitness bracelet is a reliable device, but even it sometimes fails. Hanging occurs in different ways: the screen does not respond to touch, the bracelet does not sync with the smartphone, shows incorrect time or stops turning on, most often after a firmware update, prolonged inactivity or mechanical damage (for example, moisture).

Rebooting is the first step to reset, and 80 percent of the time, it solves the problem without going to the service center, but it's important to distinguish between a freeze and a hardware malfunction, and if the bracelet doesn't respond to a reboot, doesn't charge, or if artifacts (strips, flickers) appear on the screen, it could be a damaged battery or controller, and in such cases, diagnostics will be required.

In this article, we will look at all the ways to reboot the Mi Band 4, from standard to forced, and also discuss how to avoid hanging in the future.

Method 1: Software reboot through the bracelet menu

If the Mi Band 4 screen responds to touch, but the device is unstable (e.g., not synced with the Mi Fit app or showing errors), try the standard reboot.

Instructions:

1. Swipe your finger across the bracelet screen from left to right to open the menu.
2. Find the icon. ⚙ Settings (cogs) and tap it.
3. Scroll down the list and select Reboot (or Reboot in English firmware).
4. Confirm the action by touching the tick ✓.

The bracelet will turn off and automatically turn on in 10-15 seconds. If after the reboot the problem remains, move to the next method.

💡

If the menu does not contain the item "Reboot", update the bracelet firmware through the Mi Fit application. In older versions of the software, this item may not be available.

Method 2: Forced button reboot (if the screen is unresponsive)

When the Mi Band 4 is completely frozen and does not respond to touch, a hardware reset will help, using a physical button under the bracelet capsule, which works even with the battery dead (if at least 5% of the charge remains).

Step-by-step:

• 🔋 Remove the bracelet capsule from the strap. To do this, pull it towards the charging contacts (they are located on the back side of the bracelet).
• 👆 On the back of the capsule, find a small recess with the words Reset or a dot next to the contacts.
• 📍 Take a paper clip, toothpick or other thin object and press the reset button for 10-15 seconds.
• 🔄 Release the button – the bracelet should vibrate and reset.

If nothing happens after pressing the button, check:

• ⚡ Charge level (plug the bracelet to charge for 10-15 minutes).
• 🔌 Clean contacts (contaminants can block the button).
• 🛠 Damage to the body (cracks or dents near the button).

Method 3: Reset via charger (if bracelet is not turned on)

If the Mi Band 4 doesn’t respond to touch or reset button, try the charging cycle, which helps wake the device up if it’s gone deep or stuck in the on phase.

How to do this:

1. Connect the bracelet to the original charger (or 5V/1A compatible).
2. Leave it to charge for 30 to 60 minutes, even if the indicator is not on.
3. After an hour, turn off the charging and press the reset button (see Method 2).
4. If the bracelet is not turned on, connect it to charging for another 2-3 hours.

Critical: Do not use chargers with voltages higher than 5V (such as those from smartphones with fast charging) this can damage the power controller of the bracelet.

Method 4: Reset to factory settings (if the reboot didn't help)

If the Mi Band 4 is turned on but not working properly (e.g., out of sync, shows errors, or discharges quickly), a complete reset may be required.This method removes all data from the bracelet, including settings and statistics, and after reset, the device will return to the "out of the box" state.

Instructions:

1. Open the bracelet menu by swiping your finger from left to right.
2. Move to the ⚙ Settings → Reset (or Reset).
3. Confirm the action by selecting ✓ Yes.
4. Wait for the reboot (can take up to 1 minute).

After discharge:

• 📱 Reconnect the bracelet to Mi Fit (re-synchronization required).
• ⚙ Set time, notifications and other settings.
• 🔄 Update the firmware to the latest version (if available).

⚠️ Warning: Resetting to factory settings does not fix hardware problems (e.g. damaged battery or screen) If the bracelet continues to glitch after reset, contact the service center.

Method 5: Flashing through Mi Fit (for power users)

If the bracelet is turned on but is not running smoothly due to a firmware failure, a forced software update will help, a method that requires a smartphone with the Mi Fit app and a stable Internet connection.

How to re-examine Mi Band 4:

1. Make sure that the latest version of Mi Fit is installed on your smartphone (download it to Google Play or the App Store).
2. Connect the bracelet to your smartphone via Bluetooth.
3. Open Mi Fit, go to the bracelet profile and find the Firmware Update section.
4. If a new version is available, click Update and wait until the process is complete (don’t turn off the bracelet!).

It takes 5-10 minutes to run the firmware.

• 📵 Do not use other Bluetooth devices nearby.
• 🔋 Make sure the bracelet is at least 50 times charged%.
• 📶 Connect your smartphone to Wi-Fi (update via mobile Internet may interrupt).

How to avoid hanging Mi Band 4 in the future: 7 tips

To ensure that the bracelet works stably, follow simple recommendations:

1. Update your firmware regularly. Xiaomi releases bug fixes. Check for updates in Mi Fit every 1-2 months.
2. Avoid full discharge. Charge the bracelet at a battery level below 20%. Deep discharge shortens battery life.
3. Clean the contacts. Sweat and dirt on the charging contacts can cause malfunctions. Rub them with alcohol wipes once a week.
4. Do not expose the bracelet to extreme temperatures. The optimal range is from -10 ° C to +45 ° C. Overheating or hypothermia can damage the battery.
5. Reset your settings before selling. If you transfer the bracelet to another user, reset to factory settings to avoid data conflicts.
6. Use original accessories. Non-original straps or chargers can cause unstable operation.
7. Reboot the bracelet once a month, which clears the cache and prevents the accumulation of errors.

💡

The most common reason for Mi Band 4 freezes is firmware failures after an automatic update. Always check reviews of the new version in Xiaomi communities before installing.
