How to reboot Xiaomi Smart Band 9: all the ways and tips

When do you need to reboot Xiaomi Smart Band 9?

The Xiaomi Smart Band 9 fitness bracelet is a reliable device, but even it sometimes crashes. Screen getting stuck, data display incorrectly or synchronization problems are signals that the gadget needs to reboot. Unlike smartphones, the smartwatch does not have an on button, so the restart process raises questions among users.

Rebooting helps in 80% of cases when the bracelet does not respond to touch, shows a synchronization error or suddenly discharges. But it is important to distinguish between a soft restart (without loss of data) and a hard reset (with a return to factory settings), the first option is safe and recommended for regular maintenance, the second is extreme measure for serious failures.

If the bracelet is just slowing down, try first to disable and reconnect it to the Mi Fitness app.This often solves sync problems without fully restarting.

Method 1: Soft reboot through the bracelet menu

The safest method, which does not require a connection to a smartphone, is suitable if the Smart Band 9 screen responds to touch, but the device is unstable.

Instructions:

• 📱 Swipe your finger up the bracelet screen to open the main menu.
• ⚙️ Find the Settings icon (cog) and tap it.
• 🔄 Scroll down to Reboot (or Restart in English version).
• ✅ Confirm the action by selecting OK.

The bracelet will turn off and automatically turn on in 10-15 seconds, and all data (steps, pulse, notifications) will be stored.

Turn off the bracelet from charging.

Make sure that the battery is > 20%

Close the Mi Fitness app on your phone

Place the bracelet on a flat surface-->

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

When the Xiaomi Smart Band 9 touch screen freezes and does not respond to touch, a hardware reboot will help.

Algorithm of action:

1. 🔋 Remove the bracelet from your hand and place it on the table with a screen up.
2. 🖕 Find the power button on the sidebar (a small recess next to the charging connector).
3. 🔘 Press and hold the button for 10-15 seconds until the screen goes out.
4. ⏳ Wait 5-7 seconds and press the switch again.

If the bracelet does not respond to the button holding, check:

• 🔌 Is it connected to the charger (when charging, the forced reboot is blocked).
• 💧 Is there any moisture in the connector (if the bracelet has recently come into contact with water).

Method 3: Reboot with the Mi Fitness app

If the bracelet is synchronized with a smartphone, you can initiate a restart remotely, a technique that is useful when physical access to the device is limited (for example, if it is in a case).

Step-by-step:

• 📲 Open the Mi Fitness app on your phone.
• 🔍 At the top of the screen, select your Smart Band 9 from the list of devices.
• ⚙️ Go to Device Settings (three dots in the upper right corner).
• 🔄 Find the item Reset the bracelet and confirm the action.

It takes up to 30 seconds, and when you restart, the bracelet automatically connects to the phone.

Once a week.

Only when it fails.

Never rebooted.

I don't know how to do that.-->

Important! If Mi Fitness doesn’t have a reboot option, upgrade to the latest version on Google Play or the App Store.

Method 4: Reset to factory settings (last resort)

If the bracelet has stopped responding to any commands, shows infinite boot or produces critical errors, a complete reset may be required.

• 📊 Activity statistics (steps, sleep, exercise).
• ⚠️ Notification and alarm settings.
• 🔒 Authorization data (re-association to Xiaomi account will be required).

Resetting instructions:

1. 🔋 Charge the bracelet to at least 50%.
2. ⚙️ Go to Settings. → System system → Resetting settings.
3. 🗑️ Choose Delete all data and confirm.
4. ⏳ Wait for the process to be completed (up to 2 minutes).

⚠️ Warning: Once reset, the bracelet will return to factory settings. It will be impossible to recover deleted data.

Method 5: Reboot via charger (alternative method)

A little-known but effective way is to use a charging cable to force a restart, which is suitable if the power button is not working and the screen is not responding.

How to do this:

• 🔌 Connect the bracelet to charging (use the original cable!).
• ⏱️ Hold the power button for 20 seconds (even if the screen is not changing).
• 🔄 Turn off the bracelet from charging and wait 10 seconds.
• 🔋 Connect back – the device should start loading.

This method works in 60 percent of cases where standard methods don't work, and if the bracelet still doesn't turn on, it could be the battery or the motherboard.

💡

Before using this method, make sure the charging connector is clean. Dust or moisture can block contact and prevent rebooting.

Frequent Reboot Errors and How to Avoid Them

Many users make critical mistakes when trying to reboot the Xiaomi Smart Band 9, which leads to aggravation of the problems.

Interruption of the discharge process

If you have started a hard reset (Method 4), do not unplug the bracelet from charging or press the buttons until the process is complete, which can lead to a blink (complete failure) of the device.

2. Use of non-original chargers

Cheap cables often don’t provide stable voltage, which causes reboot failures. Always use Xiaomi’s proprietary cable or certified counterparts.

⚠️ Note: If the bracelet shows an error after restarting 0x1234 Or similar code, it indicates that the firmware is damaged. You can't solve the problem yourself, you need to flash it in the service center.

Ignoring the level of charge

Trying to reboot a device with less than 10% battery power can cause it to shut down completely and lose data.Always check the charge level before manipulation.

💡

If the bracelet does not turn on after all attempts to reboot, the problem is more hardware (battery, board).In this case, self-repair is not recommended - contact the authorized Xiaomi service.
