If you've recently noticed that your wireless headphones If the connection cuts out, the clock unexpectedly disconnects, or the music skips, you're not alone: ​​several users have detected this. Bluetooth issues on some Xiaomi phonesThe good news is that, as is often the case with software errors, most can be fixed with a patch or fine-tuning, provided there is no physical damage to the wireless module.
Specifically, annoying behavior has been identified with cuts and interruptions during Bluetooth connections in certain models. The company is already aware of the problem and is working on a fix. While we wait for a permanent solution, here's everything you need to know: which phones are affected, how to update, how to diagnose whether it's a hardware or software issue, and a range of tips to prevent Bluetooth from turning on by itself or becoming unstable.
What's happening with Bluetooth on Xiaomi phones and which phones are involved?
The most common symptom is micro-cuts between the phone and the device Connected via Bluetooth. In headphones, this is perceived as pauses and clicks; in watches or bracelets, as sporadic disconnections that prevent a smooth experience when receiving notifications or syncing data.
According to user reports, the problem appears with a completely normal use This affects headphones, wearables, fitness trackers, speakers, and other wireless accessories. While a widespread issue across the entire product range hasn't been confirmed, two models account for the majority of reported problems.
The phones identified to date are the following, along with the HyperOS versions where the interruptions have been observed:
- LITTLE X5 Pro 5G: OS2.0.1.0.UMSRUXM, OS2.0.3.0.UMSMIXM and OS2.0.3.0.UMSEUXM.
- Xiaomi 11 Lite 5G: OS2.0.1.0.UKORUXM, OS2.0.1.0.UKOMIXM and OS2.0.1.0.UKOEUXM.
It has been mentioned in the official forums that it is a software flaw already identified A fix update will be released. If you own one of these models, keep an eye on upcoming HyperOS releases and install the patch that stabilizes the connection as soon as possible.
The official way: HyperOS updates that improve Bluetooth
In addition to the specific patches that fix bugs, Xiaomi has released improvements aimed at expanding compatibility and strengthen Bluetooth stability. These updates positively impact sound quality, speed up accessory recognition, and optimize power consumption.
Among the most interesting changes are the following: more stable and faster connections, support for a larger number of headphones (including quick connection with pop-up window), improved detection of third-party accessories, refined power management and pairing protocols more efficient.
To take advantage of these improvements, some devices allow you to review and install the bluetooth version You can do it directly from the settings, without waiting for a full system update. If your phone supports it, the process is very simple.
- Open Settings and go to the section Bluetooth.
- Below the device name, look for the option Bluetooth version.
- If an update is available, tap to install the latest version.
Note that this option is not available on all models or builds, but when it appears, it allows you to incorporate minor improvements without changing system versionIf you don't see it, don't worry: updates will still arrive through System Settings.
Diagnosis: Rule out a hardware failure using the CIT menu and the engineer code
Before taking further steps, it's advisable to rule out a damaged Bluetooth module. MIUI and HyperOS include a internal testing menu (CIT) which will help you check the hardware status and clear up any doubts in a minute.
To access the CIT from your Xiaomi settings, do the following and you'll see if there's a physical error or if everything points to a software issue:
- Go to Settings > About phone.
- Sign in All specifications.
- Press 5 times in a row on Kernel version until the CIT menu opens.
Once inside, locate the evidence of Bluetooth and run it. If the test passes, you're most likely dealing with a software problem (configuration, permissions, interference) and not due to a physical failure of the chip.
You can also open the engineering menu using the phone's dialer: * # * # * # * # 6484From there you have access to tests for Wi-Fi, camera, color, software version, and, of course, Bluetooth. It's a quick way to check the status without going to a repair shop.
Why does Bluetooth turn on by itself and how to prevent it?
A very common trigger is interaction with Wi-Fi: activate or deactivate the wireless networkGoogle services are activated that search for nearby devices and, consequently, force the use of Bluetooth. This is not by chance: it occurs when the system attempts to locate and pair devices in the vicinity.
In addition, there are apps that, with expanded permissions, can enable Bluetooth in the background Without asking you to do anything. Even if you installed them from Google Play, they can use system services to turn it on. If Bluetooth suddenly appears to be on, this could be the reason.
Start by checking if any recent app is causing the ignition and who has the hand to manage the connection:
- Sign in Settings> Bluetooth.
- Opens Additional adjustments and check which services last activated it.
- Sign in Settings > Apps > Permissions and check the Bluetooth permission, in addition to the Autostart in the background.
We recommend you revoke unnecessary permits Block apps that shouldn't manage nearby devices (sports, health, automation, media players), and disable their auto-start if you don't need it. Keep all your apps updated to avoid behaviors already fixed by their developers.
Another source of "phantom" ignitions are the modes of concentration or profiles that, when activated, execute predefined actions. If any of these profiles are instructed to connect or disconnect Bluetooth, it will alter your settings. Go into the mode settings and remove any automations related to this connection.
Finally, disable the constant device search, which can generate a struggle between your manual order and the system's orderThe exact route is:
- Go to Settings.
- Sign in Location.
- Opens Wi‑Fi and Bluetooth Scanning.
- Turn off the bluetooth search automatically.
Adjustments and practical solutions without deleting your data
If you still experience instability after trying the above, it's a good idea to... reset network preferencesThis clears caches and removes previous links that might be corrupted, without deleting photos or files.
To do it in MIUI/HyperOS, follow these steps:
- Sign in Settings.
- Go to Connect and share.
- press Restart Wi-Fi, mobile networks, and Bluetooth.
- Confirm in Recover settings.
After the network restart, Bluetooth is disabled. turned off for a couple of minutes This will restart all processes from scratch. If you want to be more precise, restart your phone as well and wait another couple of minutes before reactivating the connection.
Regarding whether it's bad that Bluetooth turns on by itself: it doesn't pose a direct safety hazard Because, for someone to connect, manual pairing is required. Even so, it's best to avoid this to prevent wasting battery power or emitting a signal unnecessarily.
In terms of privacy, remember that even without being paired, Bluetooth periodically issues an identifier (UUID) This allows other devices to recognize you. In theory, this information could be used to locate the device, which is why many users prefer to turn it off when they don't need it.
Advantages of turning it off? Besides slightly improving the autonomyThis prevents accidental pairings. However, if you frequently use headphones, a watch, or a speaker, the convenience of having it active or in quick connection mode outweighs the need to keep it switched on throughout the day.
You updated and it's still failing: latest steps, reset, and support
There are cases in which Errors appear after updating to a new version of MIUI/HyperOS or a security patch. If this has happened to you, try the options above in that order. If you don't see any improvement, you have three options left: wait for a new patch, leave Bluetooth always on as a temporary solution, or reset phone.
A factory reset erases all your data, so first perform a Backup (in the cloud, on a computer, or both), including chats from apps like WhatsApp. Once you have that, do the following:
- Go to Settings.
- Sign in Over the phone.
- Choose Factory reset.
- press Delete all data and confirm with your credentials.
If your phone didn't come with the operating system version you updated to, it might be carrying over old files that could cause problems. In that case, a hard reset from recovery mode leave the installation clean:
- Turn off the phone.
- hold power + volume up until you see the Xiaomi logo.
- Browse with volume up to Clear data / Wipe Data and confirm with the power button.
- Finally choose Reboot System Now.
If this doesn't fix the problem, it's time to contact the Xiaomi technical support to assess repair. If there is a hardware defect, the device may need to be opened. Pay attention to the guarantee conditionsImpacts or liquid damage usually exclude coverage, but in most cases of non-induced failure, repair is covered.
Extra tips and useful notes
To improve the audio you can adjust the Bluetooth codec If your phone and headphones allow it, switching to a more stable or efficient codec can improve both quality and latency, especially if you're experiencing interference.

FAQs
Why does my Xiaomi turn on Bluetooth on its own?
Two causes stand out: the option of Wi‑Fi and Bluetooth Scanningwhich keeps the scan active even if you manually disable the connection, and the applications with special permissions (or Google services) that can turn on Bluetooth to locate nearby devices without notifying you.
Does it pose a security risk if it activates automatically?
It is not serious in itself, because You cannot match without your actionEven so, when it's on it consumes slightly more battery and emits an identifier (UUID) that, in theory, could be used to track the device. If you don't need it, it's best to keep it turned off.
How do I check if it's a hardware failure?
Use the CIT modeGo to Settings > About phone > All specifications and tap Kernel version five times. Run the Bluetooth test. You can also check * # * # * # * # 6484 in the Phone app to access the engineer menu and launch the corresponding test.
If you experience intermittent Bluetooth disconnections or random activations on your Xiaomi device, Check if your HyperOS model and version are affectedInstall available updates (including the Bluetooth version if your phone offers it), rule out physical problems with the CIT, check permissions, automations, and device discovery, and reset the networks if the problem persists. For stubborn cases after updating, consider the path of restoration Or contact official support; keeping up with HyperOS patches is often the key to restoring a stable, uninterrupted connection.
