How to reboot Xiaomi Mi Band 4: everything from soft reset to forced reboot

The Xiaomi Mi Band 4 fitness bracelet has become a real bestseller thanks to its combination of affordable price and rich functionality. However, even such a reliable device sometimes requires a reboot — whether after a firmware update, when the screen freezes or to fix minor software glitches. Unlike smartphones, where reboots are intuitive, with smart bracelets, it is not so obvious: there are no physical buttons, and the touch screen may not respond to touch.

In this article, we'll look at all the ways you can reboot the Mi Band 4, from standard soft resets to forced methods that can help even if you freeze completely. You'll learn how to perform the procedure correctly without risking damage to the device, what errors users most often make, and what to do if the bracelet does not respond to any actions. And for those who are afraid of losing data, we've prepared a unique guide to save statistics before reset.

Why you might need to reboot Xiaomi Mi Band 4

Rebooting the bracelet is not just about turning it off and on, it helps solve a number of problems that Mi Band 4 owners face.

• 🔄 Screen freeze – the bracelet does not respond to touch, shows the same screen or does not turn on at all after pressing the button.
• 📱 Synchronization problems – step, pulse, or sleep data is not transmitted to the Mi Fit or Zepp app despite a stable Bluetooth connection.
• 🔋 Fast battery discharge – the bracelet discharges in a few hours instead of the promised 20 days, which is often due to background firmware failures.
• 📲 Errors after the update – incorrect operation of new functions or complete inoperability of the device after installing the latest version of the software.
• 🎯 Sensor failures – the pulsemeter shows inadequate values (for example, 220 beats per minute at rest), and the pedometer resets the data.

Interestingly, many users mistakenly think of reboot and factory reset as the same thing, but they are different procedures: a reboot simply restarts the system without affecting user data, whereas a reset removes all the information from the wristband. In 80% of cases, it is enough to reboot, it is less radical and does not require reconfiguration of the device.

⚠️ Warning: If your Mi Band 4 stopped responding to touches after falling or getting moisture, rebooting is unlikely to help.In this case, the problem is likely hardware - you need a diagnosis of contacts or a display.

Method 1: Soft reboot through the bracelet menu

This is the safest and most recommended method to try first, which does not require a smartphone connection and is performed directly on the bracelet, and is suitable for cases where the Mi Band 4 reacts to touch, but works unstablely.

To perform a soft reboot:

1. Swipe your finger across the bracelet screen from left to right until the More menu (three-dot icon) appears.
2. Slip the Settings (cog) icon.
3. Scroll down the list and select Reboot (circular arrow icon).
4. Confirm the action by tapping the tick or OK button.

The bracelet will start the reboot process, which will take about 10-15 seconds, the Mi logo will appear on the screen, and then the device will return to working condition, all your data (steps, pulse, alarm settings) will be stored.

Make sure the bracelet is at least 20% charged | Disable the Bluetooth bracelet in the phone settings | Close the Mi Fit/Zepp app on your smartphone | Prepare data for synchronization after rebooting-->

If problems persist after the reboot (for example, the bracelet still doesn’t sync), try a forced reboot or reset via the app. It’s also worth checking the firmware version – an update may be needed.

Method 2: Forced reset (if the bracelet is getting stuck)

When the Mi Band 4 completely stops responding to touch, and the screen either freezes in one image or does not turn on at all, a soft reboot through the menu is not available, in which case a hardware reboot that simulates battery extraction (although it is, of course, non-removable in the bracelet) will help.

For forced reboot:

1. Remove the bracelet from your hand and place it on a flat surface with the screen up.
2. Find charging contacts (two metal strips) on the back of the device.
3. Connect the bracelet to the charger (you can use the original cable or any pogo-pin compatible connector).
4. Hold your finger on the touch button (under the screen) for 10-15 seconds until the bracelet vibrates and reboots.

If the bracelet doesn’t respond to this, try an alternative method:

• 🔌 Connect the bracelet to charging and leave for 30-60 seconds.
• 🔄 Turn off the cable and reconnect it – sometimes it works as a “push” to start.
• 📱 If there is a reaction but the screen is not turning on, try syncing the bracelet with the Mi Fit app – sometimes this helps to wake up the device.

⚠️ Warning: Do not use foreign objects (clips, needles) for forced reboot - this may damage contacts or the screen.

Method 3: Reboot via Mi Fit or Zepp

If the wristband is touch-sensitive, but you prefer to control it via your smartphone, you can reboot it remotely, and this is convenient because it doesn't require manipulation of the device itself, it's done through the app, but it only works with a stable Bluetooth connection.

Instructions for Mi Fit:

1. Open the Mi Fit app on your smartphone and wait for synchronization with the bracelet.
2. Go to the Profile section → Xiaomi Mi Smart Band 4.
3. Slap the icon. ⋮ (three points) in upper right corner.
4. Select the Reboot device and confirm the action.

For the Zepp app (if you use it instead of Mi Fit):

1. Launch Zepp and select your bracelet from the list of devices.
2. Go to the Device Settings → Additionally.
3. Find the Reboot option and confirm its execution.

The advantage of this is that you can save data before you reboot by syncing it to the app, but if the problem is that there's no connection between the wristband and the phone, it won't work, you'll have to use hardware reboot.

💡

Before restarting through the app, check if your smartphone is Bluetooth enabled and if the bracelet is within range (not more than 10 meters). If the sync is not working, try reconnecting the device in Bluetooth settings.

What to do if the bracelet is not reloaded

In rare cases, the Xiaomi Mi Band 4 can “hang so hard” that none of the methods described help. This can occur due to serious firmware failures, hardware damage, or conflicts after a failed update. If the soft and forced reboot did not work, try the following steps:

If none of the methods worked, and the bracelet still shows no signs of life, there may have been a loader failure or damage to internal memory, and there are two options:

• 🔧 Manual firmware through special utilities (e.g. Mi Band 4 Tools) This method requires experience and can lead to complete loss of performance if executed incorrectly.
• 🛠️ Contact the service center, especially if the bracelet is warranty. Xiaomi often meets and restores the device even after a failed firmware.

⚠️ Attention: Do not try to disassemble the bracelet yourself - its body is glued together, and when opened, you risk damaging the tightness, which will lead to moisture and final failure.

How to save data before rebooting or resetting

One of the biggest fears users have when rebooting the Mi Band 4 is losing the statistics they've accumulated -- steps, sleep, workouts. Fortunately, a soft reboot doesn't delete data, but if you're planning a full reset or firmware, you should take care of backup. Here's how to do it:

Methods of data retention:

• 📲 Synchronization with Mi Fit/Zepp — Before you restart, open the app and wait for full sync. The data will be stored in the cloud and restored after you connect the bracelet.
• 📊 Export statistics – Mi Fit can export data in the format CSV or GPX (for training) through the Profile section → Settings → Export of data.
• 🔄 Backup of settings – some third-party applications (for example, Notify & Fitness for Mi Band) allow you to create a backup of user settings (dials, alarm clocks).

Important: If you reset to factory settings, all data on the bracelet itself will be deleted, but the information already synced with the application will remain in the cloud. After reconnecting the bracelet, the statistics for the previous days will be restored automatically (provided that you use the same Xiaomi account).

Frequent Reboot Errors and How to Avoid Them

Many users make the same mistakes when trying to reboot the Xiaomi Mi Band 4, which only makes the problems worse.

• ⏳ Holding the sensor too short — in a forced reboot, you have to hold your finger for at least 10 to 15 seconds, not 2-3, as many people do.
• 🔋 Reboot at low charge – if the battery level is below 10%, the bracelet may not complete the process correctly and “block.
• 📱 Use of non-original chargers – cheap pogo-pin cables can communicate poorly or provide unstable voltage, leading to failures.
• 🔄 Interrupting the process – if the bracelet has started to reboot, do not turn it off from charging and do not press the sensor until it is complete (until the main screen appears).
• 🛠️ Self-repair – attempts to open the case or “reflash” the bracelet without experience often end in final breakdown.

Another common mistake is ignoring firmware updates. Many of the Mi Band 4 malfunctions are fixed by installing the latest software. Check the firmware relevance in the Mi Fit app (Device Profile → Firmware Update) If a new version is available, update the bracelet before restarting - this can solve the problem without additional manipulation.

💡

If the bracelet has been frozen after a firmware update, don't panic, that's normal. Give it 5-10 minutes to complete the internal processes. If there's no reaction after that time, do a forced reboot.
