Smart gadget owners often wonder how to turn off Bluetooth on Xiaomi’s fitness bracelet to save battery power or solve connectivity problems. However, the Mi Band architecture is designed in such a way that completely turning off the radio module without turning off the device itself is impossible. This is done to ensure constant data synchronization and instant notifications.
However, there are software-based ways to minimize wireless activity: you can cut off your smartphone, activate Do Not Disturb, or force your device to shut down, and understanding these mechanisms will allow you to flexibly manage the power consumption of your wearable device.
In this article, we will take a closer look at all the available connection management methods, and we will look at the settings in the Mi Fitness and Zepp Life app, and explain why the standard bracelet menu does not include the “Switch off Bluetooth” button.
Bluetooth Low Energy Architecture in the Mi Band
Xiaomi fitness trackers run on Bluetooth Low Energy (BLE) protocol, a technology designed specifically for low-power devices. Unlike classic Bluetooth in headphones or speakers, BLE consumes minimal energy even in an active standby state.
When you see the bracelet connected, it doesn't transmit data continuously. It only communicates in short pulses when you synchronize or when you receive a notification, which is why trying to turn off Bluetooth manually often doesn't give you any visible boost in autonomy compared to normal operation.
Xiaomi Wear system software does not provide user access to control the radio module, this is a restriction laid down at the firmware level to prevent situations where the user accidentally breaks the connection and stops receiving important health data or calls.
⚠️ Warning: Attempts to flash the device to obtain root rights to disable Bluetooth can lead to irreversible firmware damage and loss of warranty.
It’s also worth noting that constantly searching for a smartphone device can drain your phone’s battery power. If you want to save energy on your phone, it’s easier to temporarily turn off Bluetooth in the settings of the smartphone itself than to try to manipulate the bracelet.
Use of the "Do Not Disturb" mode
The closest analogue to disabling active communication functions is the Do Not Disturb mode, which, when activated, stops vibrating when incoming calls and messages are sent, although the background connection to the application can be maintained to synchronize steps.
To activate this mode on the device itself, you need:
- 📲 Wake up the bracelet screen by touching or raising the wrist.
- 🔍 Swipe your finger across the screen to the “More” menu or settings icon.
- 🌙 Find the icon "Do Not Disturb" (usually depicted as a month or crossed out bell).
- ✅ Click to activate by confirming the choice.
In this state, notifications are blocked, which reduces the activity of the vibrator and the backlight of the screen. This is the main way to make the bracelet "quiet" without losing the functionality of the activity tracker.
You can also set a schedule for this mode. In the Zepp Life app, go to the device profile, select "Do Not Disturb" and set time intervals, for example, from 23:00 to 07:00, during which time the screen of the gadget will go out faster and the vibration will turn off.
💡
Use Do Not Disturb in theaters or meetings to keep the bracelet screen from lighting up with every hand movement, saving up to 15% of your charge per day.
Breaking the connection via Mi Fitness and Zepp Life app
If your goal is to completely stop the exchange of data between the wristband and the phone, the most effective way is to break (pairing) in the application settings, which effectively disables Bluetooth communication until the moment you reconnect.
The procedure for disconnecting the link is as follows:
- 📱 Open the Mi Fitness (or Zepp Life) app on your smartphone.
- 👤 Go to the “Profile” tab or click on the image of your device.
- 🔻 Scroll down the menu to the bottom of the item "Untie" or "Delete device".
- 🗑️ Confirm the action in the dialog window that appears.
After this operation, the bracelet will go into search standby mode, it will broadcast the signal for connection, but will not transmit health data or notifications, which can be considered a conditional shutdown of Bluetooth functions.
It's important to understand the difference between turning off your phone's settings and undocking in your app. If you just turn off Bluetooth in the curtain of your phone, the bracelet will keep trying to connect, using its charge. The undocking in the app gives you a cleaner disconnect.
Forced shutdown of the device
The only way to guarantee a 100% shutdown of the Bluetooth module is to turn off the fitness bracelet completely. When switched off, the radio module neither consumes power nor emits a signal.
To perform this operation on the Mi Band 6, Mi Band 7 and later models:
- 💡 Activate the device screen.
- ⚙️ Swipe right or left to the "Settings" (cog icon).
- 🛑 Find the "System" or "Switch off" option immediately".
- 👆 Press and hold the off icon during 3-5 seconds.
On older models, such as the Mi Band 4, the menu may be different, so you need to find System -> Power off. Once turned off, the MI logo may appear on the screen, and then the screen will go out.
It also turns on by long pressing the touch button or connecting to the charger, the only regular method that physically shuts down the communication module.
☑️ Pre-off check
Comparison of methods of connection management
To make it easier to choose the best way to control your gadget, we have compiled a comparative table of different methods, which will help you to understand which option is best suited for your particular situation.
| Method | Battery consumption | Receipt of notifications | Synchronization of data |
|---|---|---|---|
| Active regime | Standard. | There is. | Automatic. |
| Don't disturb. | Downsized. | Visual only. | Automatic. |
| The gap in the annex | Minimum | No. | Absent. |
| Shutting down the device | Absent. | No. | No. |
As you can see from the table, Do Not Disturb mode is the middle ground for those who want to save charge but are not willing to sacrifice the functionality of the tracker.
Using energy-saving mode (if available in your firmware version) can also limit background processes, although it doesn't directly disable Bluetooth.This mode often turns off constant heart rate monitoring and increases synchronization intervals.
Managing Notifications to Save Energy
Frequent vibration and screen lighting are the main energy consumers after the radio module itself. By turning off unnecessary notifications, you will significantly reduce the activity of the Bluetooth channel, since the bracelet will not need to wake up often to receive data packets.
Set up the app list in the app notifications menu in Zepp Life. Leave only critical messengers like Telegram or WhatsApp. Turn off notifications from social media, games and news feeds.
⚠️ Attention: Disabling system notifications Android/iOS This can cause the bracelet to stop vibrating even when incoming calls are made, unless an exception is configured.
It is also recommended to disable the function "Raise the wrist to turn on the screen", which will reduce the number of false activations of the screen and, as a result, the frequency of access to the sensors and communication module.
