How to reboot Xiaomi Mi Band 4: from soft restart to reset to factory settings

The Xiaomi Mi Band 4 fitness bracelet is one of the most popular wearables due to its combination of functionality and affordable price. However, even such a reliable technique sometimes fails: the screen stops responding to touch, the data does not sync with the smartphone, or the bracelet completely freezes on the Mi logo. In 80% of cases, these problems are solved by a simple reboot, but not all users know how to do it correctly without risking losing accumulated data about training and sleep.

In this article, we’ll look at all the ways you can reboot the Mi Band 4, from a standard soft restart to a forced reset that can help even if you’re stuck, and how to distinguish between a temporary glitch and a serious malfunction, and what to do if the bracelet doesn’t respond to any manipulation, and the instructions are suitable for all firmware versions, including the latest updates from 2023 to 2026.

When do I need to reboot Xiaomi Mi Band 4?

Rebooting is not a panacea, but it often helps to get the bracelet back to normal without going to the service center.

• 📵 The bracelet does not sync with the Mi Fit or Zepp Life app (errors like “Device disabled” or “Unable to connect»).
• 🖥️ The screen is getting stuck on the Mi logo or shows a white/black screensaver for more than 5 minutes.
• 🔄 Touch Display does not respond to swipes or taps (or reacts with a delay).
• 🔋 Fast battery discharge (bracelet discharges in a few hours instead of the standard 10-15 days).
• 📊 Step, pulse, or sleep data are reset or displayed incorrectly.

If the problem is systemic (e.g., the bracelet is not switched on at all or is physically damaged), a reboot is unlikely to help, requiring a diagnosis at a service center, but in most cases, a restart eliminates software failures caused by:

• 📲 Firmware update conflict (especially if the update is interrupted).
• 🔌 Unstable Bluetooth connection with smartphone.
• 📱 Failures in the Mi application Fit/Zepp Life.
• 🔋 Critical battery discharge (if the bracelet is turned off to zero»).

⚠️ Warning: If the bracelet has stopped responding after falling, getting moisture or mechanical impact, do not try to reset it yourself. This can aggravate the damage.

Method 1: Soft reboot (restart via menu)

This is the safest method, and it doesn't cause data loss, and it's good if the bracelet is on and it's partially responsive to touch, but it's unstable.

1. Swipe your finger across the Mi Band 4 screen to the left or right until you find the Other (it is marked with three dots).
2. Slip on More, then scroll down to the Reboot point (on some firmware - Restart).
3. Confirm the action by clicking on the tick or OK button.

The bracelet will turn off and automatically turn on in 10-15 seconds. After the reboot, check if your data (steps, pulse, training) is stored - it should not be reset.

Turn off the bracelet from charging (if it is connected)

Make sure the charge level is above 20%

Close the Mi Fit/Zepp Life app on your smartphone

Wait 1-2 minutes after restart before connecting to the phone-->

If Reboot is not on the menu, your firmware does not support this option, then move to the next method.

Method 2: Forced reset (hard reset)

This method is used when the bracelet is completely frozen and does not respond to touch, or if a soft restart does not help.Forced reboot resets all temporary data in the device's memory, but does not delete basic settings and statistics (they are stored in the application on the smartphone).

Instructions:

1. Remove the bracelet from your hand and place it on a flat surface with the screen up.
2. Find the touch button below the screen on the case (it is located below the display, but is not a physical key).
3. Press the area under the screen (where the button is) and hold it for 10-15 seconds until the bracelet vibrates and goes out.
4. Release the button. In a few seconds, the Mi logo will appear on the screen, which means a successful reboot.

If the bracelet doesn't vibrate or turn off, try repeating the action while simultaneously touching the screen at the top (where the time is displayed), which sometimes helps with deep freezes.

⚠️ Warning: Don't confuse forced reset with factory reset (discussed below) Hard reset doesn't delete your data, whereas reset erases all bracelet settings.

💡

If the bracelet does not respond to the hold of the button, connect it to charge for 5-10 minutes, then try again. Sometimes the discharged battery blocks the execution of commands.

Method 3: Reset to factory settings (full reset)

This method should only be used as a last resort if the first two methods did not work.

• 🔄 Account binding Mi/Zepp.
• ⏰ Settings of alarm clocks and notifications.
• 🏃‍♂️ Personal data (height, weight, target number of steps).
• 🔋 Data on the last workouts (if they are not synchronized with the phone).

Statistics already stored in the Mi Fit or Zepp Life app will remain intact, but unsynchronized data will be lost.

Resetting instructions:

1. Make sure that the bracelet is charged at least 50% (otherwise the reset may be incorrect).
2. Go to the bracelet menu, swiping left/right to the item Still.
3. Select Reset (or Reset factory settings).
4. Confirm the action by clicking the tick. The bracelet vibrates and reboots.

After the reset, you will need to re-assign the bracelet to your account through the app.

1. Open Mi Fit or Zepp Life on your smartphone.
2. Go to the Profile section → My devices.
3. Click Add Device and follow the instructions on the screen.

💡

Factory reset is the last option when other methods have failed. Always try a soft or forced reset first.

What to do if the bracelet is not reloaded?

If none of these methods worked and the Mi Band 4 still doesn’t respond, try the following steps:

1. Check the charging: 🔌 Connect the bracelet to the original charger for 30 to 60 minutes. Sometimes a deep discharge blocks any action. 🔋 Try another charger or USB-port (for example, from a computer instead of a socket).
2. Clear the contacts: 🧴 Gently wipe the charging contacts on the bracelet and cable with a cotton swab soaked in alcohol. ⚠️ Do not use sharp objects – it can damage your contacts.

Check for physical damage:

• 🔍 Inspect the body for cracks, dents or traces of moisture.
• 💧 If the bracelet is wet, put it in rice or silica gel for 24 hours before trying again to turn on.

If after these manipulations the bracelet still does not show signs of life, perhaps the problem is in the hardware:

• 🔋 Failure of the battery (swelling, short circuit).
• 📱 Damage to the motherboard (for example, after a fall).
• 💧 Corrosion of contacts due to moisture.

In such cases, self-repair is not recommended - contact the authorized service center Xiaomi. the average cost of diagnosis is 500-1000 rubles, and repair (for example, replacing the battery) will cost 1500-2500 rubles.

How can we avoid disruptions in the future?

To minimize the risk of hanging out and the need for frequent reboots, follow these guidelines:

• 📱 Update your firmware regularly through Mi Fit or Zepp Life. Updates often include fixes for critical bugs.
• 🔋 Don't let the bracelet run completely - charge at a battery level below 20%.Deep discharge shortens battery life.
• 📵 Turn off unnecessary notifications. Excessive alerts can overwhelm the bracelet system.
• 🚿 Avoid prolonged contact with water despite the claimed level of protection of 5. ATM. After swimming or shower, wipe the bracelet with a dry cloth.
• 📲 Reload the bracelet every 1-2 months to clean the cache (even if there are no failures).

Important: If you use informal firmware (such as Amazfit or custom modifications), the risk of failure increases 3-4 times.

Also note the compatibility of the smartphone. bracelet Mi Band 4 works optimally with phones on Android 6.0+ or iOS 10.0+. On older versions, there may be problems with synchronization, which are mistaken for bracelet failures.
