How to Reboot Xiaomi Smart Band 9: 5 Proven Ways

The Xiaomi Smart Band 9 fitness bracelet became one of the most popular gadgets of 2026 thanks to a combination of affordable prices, stylish design and advanced health monitoring features. However, even the most reliable technology sometimes fails: the screen stops responding to touch, data synchronizes with errors, or the device simply “hangs” on the logo. In 80% of these cases, the usual reboot helps – a procedure that many users are afraid to perform for fear of losing data or breaking the device.

In fact, the Smart Band 9 reboot is the standard diagnostic procedure provided by the manufacturer. It does not delete your personal data (steps, pulse, sleep) if done correctly, but allows you to “reset” temporary software errors. In this article, we will discuss all the current ways of rebooting, from soft restart to forced reset, and also explain how to avoid typical errors that can turn a simple procedure into a serious problem.

When do you need to reboot Xiaomi Smart Band 9?

Before you start to act, it is important to understand whether your bracelet really needs to be reset, and here are the key symptoms that indicate a restart is needed:

• 📵 The screen does not respond to touch or responds with a delay of more than 3 seconds.
• 🔄 The bracelet is constantly reloaded on its own (cyclic loading).
• 📱 Mi Fitness (or Zepp Life) app doesn't see the device, though Bluetooth is enabled.
• 🔋 The battery charge indicator shows incorrect values (for example, 100% → 1% per minute).
• 🚨 There are errors in data synchronization (steps, pulse, sleep do not persist).

If you see any of these signs, it's likely that the bracelet software has failed, and 95% of the time, a soft reboot helps, it doesn't affect user data and takes less than a minute, but if the problem recurs regularly, it can indicate a deeper problem that requires a firmware update or even a service center.

⚠️ Note: If the Xiaomi Smart Band 9 bracelet doesn’t turn on at all (no vibration, no screen lights), rebooting won’t help.In this case, check the charger and cable, and also try to connect the bracelet to another power source. The problem may be a dead battery or a damaged port.

Method 1: Soft reboot through the bracelet menu

This is the safest and most recommended method by the manufacturer, and it doesn't affect the stored data, and it's good for minor failures.

1. Check that the bracelet is on and the screen responds to touch.
2. Swipe your finger up the screen to open the main menu.
3. Find the icon. ⚙️ Settings and tapping on it.
4. Scroll down to System → Reboot.
5. Confirm the action by pressing OK.

The bracelet vibrates and starts the reboot process, which takes about 20-30 seconds. Once turned on, all your data (steps, pulse, settings) will remain in place. This method works even if the bracelet is connected to the phone via Bluetooth.

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

Make sure your battery level is above 10%

Close the Mi Fitness/Zepp Life app on your phone

Do not press buttons during reboot-->

If the Reboot item is not in the menu (this happens after firmware updates), try an alternative way:

Settings → About the device → Reboot

Method 2: Forced button reboot (hard reset)

If the bracelet screen doesn't respond to touch, or if the device is stuck on the Mi logo, you'll have to use hardware reboot, which resets all the time processes, but doesn't delete user data. Here's how to do it:

1. Remove the bracelet from your hand and place it on a flat surface.
2. Find a physical button on the case (it is located below the screen, on the right).
3. Press the button for 10-15 seconds until the bracelet vibrates and starts to reboot.
4. Release the button and wait for the full switch on (the Mi logo will appear).

This method works even if the bracelet is discharged or does not respond to the sensor. However, do not use it more often than 1 time a week - frequent forced resets can lead to wear of the button or malfunction of the firmware.

⚠️ Warning: If the bracelet freezes on the logo again after a forced reboot, this may indicate firmware damage, in which case you will need to reflash the device through official software (instruction below).

💡

If the button of the bracelet is recessed or not pressed, try using a thin object (such as a paper clip) to gently press it.

Method 3: Reboot with Mi Fitness or Zepp Life

If the bracelet is synchronized with the phone, you can initiate the reboot remotely through the official application, this method is convenient when the sensor of the bracelet is unstable, but the Bluetooth connection is active.

1. Open the Mi Fitness app (or Zepp Life for newer versions).
2. Go to the Profile section → Choose your Smart Band 9.
3. Slap the icon. ⚙️ Settings of the device.
4. Scroll down and find the Reboot Device item.
5. Confirm the action.

The bracelet will receive a command and reboot automatically, which is the most gentle way, because it eliminates mechanical pressure on the button. However, it only works when the Bluetooth connection is active. If the bracelet does not connect to the phone, use one of the previous methods.

Method 4: Reset to factory settings (last resort)

If the Xiaomi Smart Band 9 bracelet continues to glittle even after a few reboots, a complete reset may be required.This procedure deletes all user data (steps, settings, activity profiles), but often resolves serious software glitches.

Resetting instructions:

1. Open on the bracelet Settings → System system.
2. Select Resetting (or Resetting Factory Settings).
3. Confirm the action by pressing OK.
4. Wait for the process to be completed (the bracelet vibrates and reboots).

Once reset, you'll have to re-synchronize the bracelet with the Mi Fitness app and configure it as a new device. All historical data (steps, sleep, pulse) will be lost unless it's pre-synchronized with the cloud.

Method 5: Flashing the bracelet (for experienced users)

If the Smart Band 9 bracelet does not work properly after rebooting or resetting, its firmware may be damaged, in which case manual software updates will help. This method requires caution, since improper actions can permanently disable the device.

Here's how to re-flash the bracelet:

1. Download the latest firmware for Xiaomi Smart Band 9 from the official Xiaomi website or a trusted source (e.g. MIUI forum).
2. Connect the bracelet to your phone via Mi Fitness.
3. Go to the device settings → Software update.
4. Click on the icon. ⋮ (three dots) in the upper right corner and select Local Update.
5. Select the downloaded firmware file (usually with the.fw or.bin extension).
6. Wait until the process is complete (the bracelet will reboot several times).

It takes 5-10 minutes to run the firmware. Don't disconnect the bracelet from your phone or interrupt the process! After a successful upgrade, all the features should work properly.

⚠️ Note: Do not use firmware from other bracelet models (e.g. Smart Band 8 or Smart Band 7) this will cause permanent damage to the software and void the warranty.

Flashing is a last resort, and before you do it, try all the other ways to reboot and call Xiaomi for support.

• 💦 Press the reset button with wet or dirty hands, moisture can get inside the body.
• 🔋 Reset at a charge level below 10%, the bracelet may turn off during the process and not turn on again.
