Xiaomi Smart Band 9 is one of the most popular fitness trackers of 2026, but even such an advanced gadget has situations when it needs to be completely turned off.Someone wants to save charge before long storage, someone faces a screen freeze, and someone just needs to reboot the device to eliminate errors. Unlike smartphones, where the power button is always at hand, Xiaomi smart bracelets have a shutdown process hidden in the menu and has its nuances.
In this article, we will discuss all the official and alternative ways to turn off the Smart Band 9, including forced reset if the gadget does not respond to commands. You will also learn how to properly prepare the bracelet to turn off to avoid data loss, and what to do if you experience synchronization errors after turning on.
Why do you need to turn off Xiaomi Smart Band 9?
At first glance, the fitness bracelet does not need to be turned off regularly, its battery is designed for 14-21 days of battery life, but there are several scenarios when a complete shutdown becomes necessary:
- 🔋 Savings in charge during long-term storage (for example, if you do not plan to use the bracelet for several months) When the battery is turned off, it discharges 10-15 times slower.
- 🔄 Fixing software failures: screen freeze, synchronization errors with Mi Fitness, incorrect data display.
- ⚡ Preparation for firmware updates (in rare cases, the manufacturer recommends restarting the device before installing a new version of the software).
- 🛠️ Battery repair or replacement – some service centers require the device to be turned off before intervention.
It is important to understand that the Smart Band 9 does not support a “hot” reboot (like smartphones).Any power outage leads to a complete shutdown, after which the bracelet is restarted with the sensors checking and connection to the phone. This takes up to 30 seconds.
⚠️ Note: If you turn off the bracelet to save more than 3 months, we recommend charging it to 50-60% before storage. Full discharge or, conversely, 100% charge during prolonged downtime can reduce the battery life.
Method 1: Turn off via the bracelet menu (official method)
This is the most reliable and recommended method by the manufacturer, and it works on all versions of the Smart Band 9 firmware and does not require a connection to a smartphone.
- Wake up the bracelet screen by touching it or pressing a physical button (if you have one in your modification).
- Flick the menu to the right or left (depending on the settings) until you find the Settings icon (cogs). ⚙️).
- In the settings menu, select System → Turn off (or Disable Power in English firmware).
- Confirm the action by clicking the tick ✅. The bracelet vibrates and turns off in 2-3 seconds.
Have you recorded the latest training data in the Mi Fitness app?
Are notifications synchronized (if you use this feature)?
Battery charge not lower than 5% (otherwise the bracelet may not turn on without recharging)
Are alarm clocks turned off (so they don’t work during storage)-->
If the "Stop" option is not on the menu, your firmware is outdated. Update it through the Mi Fitness app (Device Profile → Software Update).
Method 2: Forced button shutdown (if the bracelet is getting stuck)
If the Smart Band 9 doesn’t respond to touching the screen or is “obsessed” with the Xiaomi logo, you can use hardware reboot.This method is also useful if the settings menu is not available due to a failure.
Instructions for forced disconnection:
- Find a physical button on the body of the bracelet (located on the side, under the top of the strap).
- Press it for 10-15 seconds until the screen goes out and the bracelet vibrates three times.
- Release the button. The device will turn off.
⚠️ Warning: Forced shutdown does not store unsynchronized data (steps, pulse, exercise) if the bracelet hovers while recording the workout, the information will be lost. To minimize the risks, try connecting the bracelet to charge for 5-10 minutes before using this method – sometimes this “freezes” the system.

Method 3: Turn off via Mi Fitness (remote)
Few people know, but the Xiaomi Smart Band 9 can be turned off remotely via the official app, which is convenient if you don't want to interact with the wristband menu or have limited hand mobility, but it only works when you're actively connected via Bluetooth.
Step-by-step:
- Open the Mi Fitness app on your smartphone.
- Go to the Profile section → Choose your Smart Band 9.
- Slap the icon. ⚙️ (Settings of the device).
- Scroll down and select Turn off the bracelet.
- Confirm the action in the pop-up window.
Note that in some regions (e.g. the EU), this item may be called Restart device due to restrictions on remotely disabling gadgets under local safety regulations.

Method 4: Deep Sleep (alternative to shutting down completely)
If you need to save charge but still be able to wake up the bracelet quickly (for example, for an alarm clock), use deep sleep mode. In this state, the Smart Band 9 consumes minimal energy, but remains partially functional:
- ⏰ The alarm clocks are triggered at a given time.
- 📶 Bluetooth connection is turned off (up to 80% charge savings).
- 🔋 The battery is discharged at speed ~1% per month.
- 🚫 All sensors (pulse, SpO₂, pedometer.
How to activate deep sleep:
- Go to the bracelet menu: Settings → System → Sleep mode.
- Choose a deep sleep (not to be confused with Do Not Disturb!).
- Set an automatic wake-up timer (for example, at 7:00) or leave manual mode.
| Regime. | Consumption of charge | Functionality | Time to wake up |
|---|---|---|---|
| Total shutdown | ~0.1% per month | Absent. | Handheld (button) |
| Deep sleep. | ~1% per month | Alarm clocks, basic notifications | Auto/manual |
| Flight mode. | ~5% per week | All sensors are active, but without Bluetooth | Instantly. |
| Regular regime | ~10-15% per week | Full functionality | No. |
💡
If you use Smart Band 9 to monitor sleep, sync the data with the app before activating deep sleep, in which the bracelet does not record sleep phases, and gaps in the statistics can distort weekly reports.
What if the bracelet does not turn on after switching off?
In 90% of cases, the problem is solved by connecting to the charger for 10-15 minutes, but if the Smart Band 9 does not show signs of life (no vibration, no charging indicator), try the following steps:
- Check the cable and adapter: use the original Xiaomi cable or a certified counterpart. Some cheap cables don't provide enough current to initialize charging.
- Clean the contacts: wipe the metal contacts on the bracelet and charger with an alcohol wipe. Oxidation or contamination can block power.
- Forced reboot: Connect the bracelet to charge. Press the physical button for 20 seconds. If the screen blinks, release the button, the device should start loading.
- Reset via Mi Fitness: Open the app, go to Device Profile → Settings → Reset. Select Restore Factory Settings (the bracelet must be connected to your phone via Bluetooth).
⚠️ Note: If the bracelet does not turn on even after reset, this may indicate a hardware malfunction of the battery or power controller.In this case, contact the Xiaomi service center!
💡
If the bracelet does not respond to charging, but is warm to the touch, this is a sign of a short circuit.
How to keep Xiaomi Smart Band 9 in the off state?
If you plan to avoid using the bracelet for more than a month, follow these guidelines to keep the battery and functionality:
- 📦 Packaging: Use the original box or antistatic bag.Do not store the bracelet with metal objects (keys, coins) that can damage the screen.
Every 3-4 months, turn on the bracelet for 10-15 minutes to discharge / charge the battery to 50%. This prevents deep discharge, which can make the battery unusable.
