How to fix Bluetooth problems on Xiaomi phones

If you've recently noticed dropouts when using headphones or sudden disconnections with your watch, you're not alone: ​​several Xiaomi users are experiencing an annoying Bluetooth bug. Although the Software bugs are usually common on mobile phones and are corrected with patches, this one in particular has become known for causing interruptions during completely normal use.

The good news is that the brand itself has acknowledged the problem and is already working on it: they are preparing a solution via an update. According to reports, it is a system error (not a hardware one) that causes cuts, micro-cuts and loss of stability when connecting Bluetooth devices, and that it can also affect wearables such as bracelets or smartwatches.

What's happening with Bluetooth on Xiaomi phones?

Several users have described the same issue: after pairing headphones or a watch, the audio cuts out, there are random pauses, or the connection drops for no apparent reason. In everyday use, this means the music stops, calls sound choppy, or the fitness tracker malfunctions. loses synchronization more than usualIt's not a widespread problem across all models, but it's frequent enough for Xiaomi to have publicly acknowledged it.

The issue originates from software. In other words, it's not a damaged antenna or a physically defective Bluetooth module. This means the solution will come with a HyperOS system update. On the official forums, moderators and brand staff have indicated that they have already... identified the causes and are working on releasing a corrective patch to normalize the stability of the connection.

Meanwhile, there are a number of steps you can take to reduce outages and rule out hardware failures, including steps to improve wireless connectivity and diagnose the module.

It's worth noting that while having Bluetooth enabled doesn't pose a direct risk, it can lead to slightly higher battery consumption and a constant emission of identifiers. Below we explain why, and how to balance this. comfort, privacy and autonomy without giving up your wireless devices.

Affected models and HyperOS versions involved

Currently, the most consistent reports point to two very popular phones: LITTLE X5 Pro 5G y Xiaomi 11 Lite 5GHowever, that doesn't mean other models are immune to the issue, only that a widespread pattern hasn't been confirmed across the rest. If you have one of these models, check which operating system version you're using.

In the case of the POCO X5 Pro 5G, crashes and interruptions have been reported in the following HyperOS builds: OS2.0.1.0.UMSRUXM, OS2.0.3.0.UMSMIXM y OS2.0.3.0.UMSEUXMThose affected describe micro-cuts with headphones and sporadic disconnections with watches, even with normal use (listening to music, calls or notifications).

For the Xiaomi 11 Lite 5G NE, the warnings point to OS2.0.1.0.UKORUXM, OS2.0.1.0.UKOMIXM y OS2.0.1.0.UKOEUXMOnce again, the pattern repeats itself: quality or stability is lost in communication with Bluetooth accessories, something that is especially noticeable in audio and automatic reconnections.

Xiaomi has confirmed that it is already working on a patch that will resolve the issue at the system level. Once the solution is validated, it will be distributed via an OTA update. Therefore, if your phone appears on the list of older builds, it is recommended to update. Stay tuned for the next version of HyperOS that reaches your region.

In parallel, the company is rolling out minor updates to the Bluetooth services framework that improve compatibility, detection, and stability. This includes expanded support for pop-up pairing headphones, which translates to faster and more robust reconnections In day to day.

Update the Bluetooth version on your Xiaomi

Not everyone knows this, but on many Xiaomi, Redmi, and POCO models, you can check and update Bluetooth-related components from the settings. These small "mini-updates" don't change the entire system, but they do update key parts of the Bluetooth framework. Improve stability, compatibility, and energy.

To check if you have any pending updates, do the following: Go to your phone's Settings, tap on "Bluetooth," and scroll down to "Device Name." In that section, on compatible models, you'll see the "Bluetooth Version" option. Tap it to force a check, and if an available package appears, proceed with the installation. fix minor bugs and increase stability with headphones, speakers or wearables and better understand the .

These updates typically include improvements such as expanding the list of headphones compatible with quick pairing, greater accuracy in detecting third-party accessories, and changes to power management to minimize battery impact. In addition, Xiaomi has been introducing more efficient pairing protocols that streamline the initial connection and subsequent reconnections.

Make sure your device is sufficiently charged before updating, and if you use a lot of software, update your device. apps that rely on Bluetooth (health, sports, or music), also check in Google Play if there are updates for those apps. Keeping everything updated greatly reduces the likelihood of... unwanted outages and disconnections when you switch between apps or change environments (for example, when turning Wi-Fi off/on).

An extra step that can help with audio is adjusting the Bluetooth codec from the developer options or the headphone manufacturer's app, provided your device allows it. This can improve latency or quality, although the underlying problem we're discussing here is resolved with the HyperOS system patch.

Testing and diagnostics: CIT menu and hidden codes

Before blaming the software, it's worth ruling out a physical problem with the Bluetooth module. Xiaomi includes an internal diagnostic tool (CIT) that allows you to run hardware tests and verify if everything is working correctly. If the test passes, you're most likely dealing with a solvable software fault with an update or with a settings reset.

To access the CIT menu: Settings > About phone > All specifications. Once there, tap five times in a row on “Kernel version” until the hidden menu opens. Inside you will see various tests (SIM, storage, LED…). Go to the Bluetooth section to launch the specific testIf the test confirms that the hardware is working correctly, you will see a message indicating this; in that case, tap "OK" and continue with the steps in this guide.

In addition to the CIT, there's a dial code that also takes you to an engineering menu with connectivity tests: open the Phone app, go to the dialer, and enter * # * # * # * # 6484From there you can run tests for Bluetooth, Wi-Fi, camera, and other functions, which will help you to isolate the source of the problem.

If the tests point to software issues, focus on permissions, automations, and resets. If they detect a hardware failure, it's best not to waste time: gather the information and contact support or the help desk. Official technical service so that they can assess the warranty repair.

Why Bluetooth turns on by itself and how to prevent it

A fairly common issue is that Bluetooth may appear as active even after you've manually disabled it. This usually happens when you turn Wi-Fi on or off because, at that moment, Google services and the background "search" function come into play to locate nearby devices. Therefore, if you don't need it, disable the option. “Wi-Fi and Bluetooth search” within Location.

To do this: Settings > Location > Wi-Fi and Bluetooth. There, turn off the Bluetooth option. This will prevent the system from activating the radio in the background to scan for devices and reduce the conflict between your manual command and the services that try to... force the connection in each change of state.

Another source of automatic startup is apps with advanced permissions. HyperOS has incorporated finer controls for managing permissions and restrictions. Go to Settings > Apps > Permissions and check which apps can access nearby devicesUse Bluetooth or run in the background. Revoke unnecessary apps, especially those that shouldn't manage the connection.

In that same section, you'll find "Background Autostart." Limit autostart to what's essential: if an app you don't use frequently launches itself and searches for devices, it can reactivate Bluetooth without you noticing. If you have questions about a specific app, you can start your phone in safe mode and check if the automatic ignition temporarily disappears.

Don't forget to check for "focus modes" or automatic profiles that activate/deactivate connections based on time or location. Sometimes these are pre-configured or activated accidentally. Go into the special features settings and check if any of these modes are enabled. Making changes to Bluetooth when it is activated.

MIUI and HyperOS also include automations and routines. Look in the Security app or in Settings > Special features > Automation. Look for rules like “when plugging in the charger,” “when opening a music app,” or “when arriving at a location,” and check if they include Bluetooth actions. Deleting or modifying these routines prevents the connection from being interrupted. turn it on without your permission.

Restart the connection and reset network settings

If the problem persists after adjusting permissions and automations, it's time for a "surgical reset" of the connection stack. This option clears Wi-Fi, mobile data, and Bluetooth preferences without affecting your photos or files. It's an effective way to clear caches and pairings that may be corrupted.

Path: Settings > Connection and sharing > Restart Wi-Fi, mobile networks and Bluetooth. Accept in “Recover settings” and confirm with your configured security method. When finished, wait a couple of minutes without activating anything to allow the system to complete the process. restart internal processes from scratch.

Next, restart your phone and re-pair the devices. Ideally, avoid restoring old pairings if the system offers them; a fresh pairing is better. Then, observe for a few hours to see if the disconnections return or if the problem has resolved. definitely resolved.

If you use many apps that interact with Bluetooth (health, fitness, music, smart home), make sure they are all up to date. Often, an outdated app can cause conflicts when managing permissions or routines, so continue with the diagnosis without updating them. lengthens unnecessarily the problem.

After an update: what to do if the problem persists

Some users have noticed these dropouts right after updating from one MIUI version to a newer one or after installing a security patch. In those cases, Xiaomi usually releases a fix soon, so it's worth waiting for the next OTA update. In the meantime, you can try leaving Bluetooth always on if that improves stability, or follow the instructions. indicated restorations in this guide.

If nothing works, consider a factory reset. Remember to back up your photos, videos, and documents, as well as chats in apps like [app name missing]. WhatsAppTo begin the process: Settings > About phone > Factory reset > “Erase all data”. Confirm with your PIN or pattern and wait for the phone to complete. term of forma tearThen set everything up as new and test Bluetooth before restoring apps.

For persistent cases, a “deep clean” from recovery (hard resetThis might be the best way, especially if your phone didn't come with the current version of MIUI/HyperOS pre-installed and you've accumulated older system files. With the device powered off, press and hold the power button and volume up button until you see the Xiaomi logo. In the recovery menu, navigate using the volume up button to... “Wipe Data”Confirm with the power button and then select “Reboot System Now”.

After any of these resets, avoid restoring old Bluetooth settings. Pair the devices again and observe the situation. If the problem persists, it's time to gather evidence (videos, screenshots, CIT report) and contact support. official Xiaomi support to expedite a warranty solution.

Security, privacy and consumption: what you should know

Bluetooth turning on by itself isn't inherently dangerous. For someone to connect to your phone, they need to manually pair it and grant permission. However, keeping it on means the phone periodically emits identifiers (like the UUID) to facilitate pairing, which could theoretically be used for track the presence of the device in certain environments.

Furthermore, although the power consumption is small, having the radio on continuously drains the battery. If you don't use accessories often, turning off Bluetooth will give you some extra battery life and improve privacy. Conversely, if you rely on headphones or a watch throughout the day, constantly turning it off and on will be inconvenient. more cumbersome than useful.

The key is to adjust permissions and automations so the system doesn't turn it on without your permission, keep Bluetooth components updated, and consider turning it off when you're not using it for extended periods. These are simple changes that, combined with Xiaomi's patch, will make the experience... much more stableIt is also advisable to learn to protect your Android to improve privacy and permission control.

Car Bluetooth: clears memories and pairs from scratch

If your connection drops mostly occur in the car, it's best to start fresh on both sides. First, delete the Bluetooth devices saved on your phone, especially those you no longer use. This helps avoid pairing conflicts that cause... failed reconnections or mid-journey audio profile changes.

Next, clear the Bluetooth memory of your car's infotainment system. Each manufacturer has its own menu, so follow your vehicle's manual to delete old or duplicate phone numbers. Once cleared, turn the car unit off and on again to ensure the system is working correctly. Reset your Bluetooth batteryIf you also use Android Auto, check how to fix Android Auto is not working to avoid further conflicts.

Finally, update the device list and pair again. In some cars, it's best to initiate pairing from your phone, and in others from the vehicle's screen, so check your manual to follow the manufacturer's recommendations. After pairing, verify that the audio and call profiles are activated and that the car has the necessary permissions. Access contacts and registration if you need it.

1. Delete from mobile all car pairings that you no longer use.
2. Clean in the car the list of linked phones following your manual.
3. Match from scratch starting from the recommended side (mobile or car).

The Bluetooth experience on your Xiaomi should return to normal: between the HyperOS patch Xiaomi is preparing, specific Bluetooth framework updates, permission adjustments, and a network stack reset where appropriate, it's possible to put the dropouts behind you. Gain stability with headphones and wearables and keep automatic activation under control without sacrificing autonomy or privacy.
