Xiaomi's modern smartphones are famous for their functionality, but sometimes over-automation causes discomfort. When you open a case and the phone itself searches for and connects the headphones or car taper that are forgotten in the bag, it's familiar to many owners. It not only drains the battery, but also creates unnecessary background connections that can interfere with the operation of other devices.
The problem is that the MIUI shell or the new HyperOS is set to maximize user experience by default, and it remembers the last successful pairs and seeks to restore the connection at the first opportunity when the Bluetooth module is activated, but for many use cases, this algorithm is redundant and even annoying.
In this article, we’ll look at all the ways you can manage your automatic connection, look at standard system settings, application rights, and hidden engineering menus, and learn to control when your smartphone should communicate with the periphery and when it’s best to stay offline.
Why Xiaomi is automatically connecting devices
The fundamental reason is the logic behind the Android operating system that Xiaomi uses. Bluetooth was originally designed to allow seamless connection between devices. When you pair gadgets, a record of trusted devices is created. The system believes that if the module is on, then the connection to the trusted device should be established immediately.
The second reason is background services. Various applications, especially those that manage audio or fitness trackers, may have priority on connectivity. For example, Xiaomi Wear or a headphone app can constantly scan the airwaves for their device, forcing the connection even against the user's wishes at the moment.
⚠️ Warning: Disabling automatic connectivity completely may result in you having to manually confirm pairing each time you remove the device from the forgotten list.Be prepared for the "out of pocket - music playing" convenience to disappear.
Also worth considering is the A2DP and HFP profiles. The phone can automatically switch the audio stream to the last active device, even if you didn't plan to use it, which often happens when you move out of Wi-Fi coverage when the system tries to switch channels.
Basic Bluetooth configuration in MIUI and HyperOS
The first and most obvious step is to work with a standard interface, and although there's no direct "disconnect auto" button on the menu, there are a number of settings that affect how the module behaves, and the first thing you need to do is check the list of connected devices, and often there are gadgets that you haven't used in a long time, but the phone keeps looking for them.
To manage the list, go to Settings → Bluetooth, which shows all previously connected gadgets. Click on the gear icon or arrow next to the device name. In the menu that opens, you can often find the option “Auto Connect” or “Automatic Connect” option. If it is worth the tick, you need to uncheck it.
- 🔹 Open Bluetooth settings and find the problem device in the list of My Devices».
- 🔹 Click on the information icon (cog) to the right of the name.
- 🔹 Look for the Auto Start or Auto Connection switch and deactivate it.
- 🔹 If there is no switch, try pressing “Forget the device” and pairing again, carefully reading the requests on the screen.
It's important to understand that new versions of HyperOS may have different interfaces, some of which are moved to Connected Devices. If you don't get autostart by standard methods, you should check the application rights. Sometimes third-party software intercepts Bluetooth control.
Managing Application Rights and Background Services
Often, the culprits of intrusive connectivity are not system settings, but specific applications. Music services, navigators, or smart home programs may have permission to use Bluetooth in the background, which allows them to initiate the connection regardless of the user’s actions.
To limit your appetite, go to Settings → Apps → All Apps. Find the app that supposedly controls your device (such as the Sony, JBL, or fitness bracelet app). Go to its settings and select Permissions.
In the permission list, look for "Bluetooth" or "Bluetooth Device." Here you can deny the app access to the module or limit it to the background mode only, and it's also helpful to check the battery settings for that application.
| Type of permit | Recommended action | Impact on autoconnection |
|---|---|---|
| Location | Only when used | Reduces scanning frequency |
| Bluetooth | Prohibit/Inquire | Blocks the initiation of communication |
| Auto-start | Shut down. | Prevents the start of service |
Pay special attention to the system service Bluetooth MIDI Service or Bluetooth Share. In some cases, resetting these system components through the menu "Apps" helps to clear the cache of errors that cause the phone to "stuck" in an attempt to connect the device.
☑️ Checking of application rights
Using Developer Mode for Fine Customization
For advanced users who lack standard tools, there is a Developer Menu, and there's a deep setup of communication protocols, and to get there, you have to click seven times quickly on the build number in the About Phone section.
After activating the developer menu, go to Additional → For Developers. Scroll down to Network or Bluetooth. Here you can find options that affect the behavior of the module. For example, “Bluetooth AVRCP Version” – changing this version may reset some profiles of automatic media management.
Another useful feature is "Switch off absolute volume." While it doesn't directly prohibit connectivity, it changes the way you interact with audio devices, which sometimes helps break unwanted automatic connections when controlling volume.
⚠️ Attention: Changing the settings in the developer menu can lead to unstable Bluetooth connection.Write down the initial settings to be able to return everything as it was.
Also in this section, you can find the item "Show all AVRCP devices." Inclusion of this optics allows you to see more details about the connected devices, but not always available on all versions of MIUI. Experiment should be careful, checking the result after each change.

Automation Scenarios as an Alternative
Instead of fighting the system, you can outsmart it with built-in automation tools. Xiaomi’s smartphones have an Auto Tasks app (or built-in Security app) that allows you to create rules that will govern Bluetooth depending on the conditions.
You can create a scenario: "If it's 23:00 to 7:00, turn off Bluetooth." Or a more complex one: "If you have home Wi-Fi, turn off Bluetooth." So you don't ban auto-connection globally, but you limit it to places and times where you don't need it.
To create a rule, go to the Safety → Autotasks app. Click Add, select a condition (trigger) and action. Select Bluetooth → Turn off as an action. This is a more flexible approach than turning off the feature completely.
- 🔹 Open the Security app on the home screen.
- 🔹 Go to the tab "Autotasks" (lightning icon or robot).
- 🔹 Press «+» create a new task.
- 🔹 Select a condition (e.g., “Application is running” or “Time”) and the action “Bluetooth off».
Using scripts is especially useful if the problem only occurs in situations such as when the phone is in your pocket or bag, which allows you to maintain functionality but remove irritants.
💡
Use geofences in scenarios: Set up an automatic Bluetooth shutdown when the phone detects you are at home or in the office to avoid connecting to nearby devices.
Resetting network settings and extreme measures
If none of the software methods worked, there may have been a build-up of configuration errors in the system, in which case a network reset might be an effective solution, not to delete your personal photos or contacts, but to clear all stored Wi-Fi passwords and Bluetooth pairs.
To perform the reset, go to Settings → Connection and Sharing → Reset Wi-Fi, mobile network and Bluetooth. Click Reset button at the bottom of the screen. The system will warn of the consequences - confirm the action.
Once you reboot, the phone will be clean in terms of network connections, you'll have to pair all the devices you need again, and often when you pair it again, the system asks for permission to automatically connect, at which point you can immediately refuse it if you request it.
| Action. | What's persisting | What's removed |
|---|---|---|
| Resetting network settings | Photos, contacts, annexes | Wi-Fi passwords, Bluetooth pairs, APN settings |
| Deletion of the annex | System settings | Data from a specific application |
| Total reset | Nothing. | All data and phone settings |
In the rarest cases where the problem persists even after a reset, the cause may be a hardware conflict or a bug of a particular firmware version. Then consider rolling back on a previous version of Android or waiting for an update in which the manufacturer will fix the error.
⚠️ Note: Before resetting your network settings, make sure you remember passwords from important Wi-Fi networks, as it will not be possible to restore them automatically.
