Are you trying to connect Bluetooth 5.2 headphones to Xiaomi, but you're not sure if your smartphone is compatible? Or are you trying to see if the seller is cheating on the old model for the new? The Bluetooth version is a critical parameter that affects data speed, connection stability, and even power consumption. Unfortunately, Xiaomi (like most manufacturers) doesn't always specify this information in the device's specifications or on the box.
In this article, we will discuss 7 ways to accurately determine the Bluetooth version on any Xiaomi, Redmi, POCO or Black Shark smartphone – from standard settings to hidden engineering menus and ADB commands. You will learn which models support Bluetooth 5.0/5.1/5.2/5.3, how to circumvent the limitations of MIUI, and why even official data can sometimes lie.
1. Verification through Android Standard Settings (MIUI)
The most obvious, but not the most reliable way, is that Xiaomi often hides the Bluetooth version in the interface, especially on budget models.
- Open the Settings. → The phone.
- Find the Device Characteristics section or All the parameters.
- Scroll down to the Communication or Wireless Networks block.
If you're lucky, there's a Bluetooth version string, but more often than not, you'll see only one. MAC-address or status On/Off. POCO F3, This is the case, but the Redmi Note 10 Pro is not.
⚠️ Attention: On some firmware MIUI (Especially global) the About phone section may display a flawed version. For example, instead of Bluetooth 5.1, 5.0 will be written, although the chipset supports a newer specification.
If there is no data in the settings, proceed to the next method.
2. Use of diagnostic applications
Specialized utilities often show more information than the standard interface. We tested 5 popular applications — here are the best ones:
- 📱 AIDA64 — It shows a Bluetooth version, chipset model, and even supported code (SBC, AAC, The free version is enough to check.
- 🔍 CPU-Z — In the System section, there's a Bluetooth Version bar.
- 🛠️ DevCheck is a minimalist interface with accurate data. LMP (Link Manager Protocol, which can indirectly determine the generation of the module.
How to check in AIDA64:
- Install the app from Google Play.
- Go to the System section → Wireless networks.
- Find the Bluetooth string and there will be a version (e.g. 5.1 (LE)).
Important: If the app shows version 4.2, but your smartphone is on Snapdragon 865 (like Mi 10), it's a bug. Try updating your firmware or using other software.
3. View through the engineering menu (#4636##)
The hidden Testing menu is available on all Xiaomi, but access to it may be blocked on some firmware.
- Open the Phone app.
- Enter the combination: ##4636## (no call).
- Select the Phone Information (or Phone Information) section.
- Scroll down to the Bluetooth block.
Here you'll see:
- 📡 Bluetooth address — MAC-address.
- 🔄 Bluetooth version – version of the protocol (e.g. 5.0).
- 🔋 Bluetooth power – current status (on/off).
⚠️ Note: On some models (Redmi) 9A, POCO M3) This menu may be missing or require root rights. If nothing happens after you enter the code, try using the menu. ADB (method).
What if the #4636## code doesn’t work?
4. Analysis of the characteristics of the chipset
If the software methods didn't work, determine the Bluetooth version by processor. Each chipset supports a specific generation of module:
| Chipset | Xiaomi models | Bluetooth version | Notes |
|---|---|---|---|
| Snapdragon 8 Gen 2 | Xiaomi 13 Ultra, POCO F5 Pro | 5.3 | Support for LE Audio and LC3 codec. |
| Snapdragon 888/870 | Mi 11, Black Shark 4 | 5.2 | Maximum speed is 2 Mbit / s. |
| Dimensity 1200 | Redmi K40 Gaming | 5.2 | Problems with aptX Adaptive on some firmware. |
| Snapdragon 778G | POCO F3 GT, Redmi Note 11 Pro+ | 5.2 | Limited support for dual Bluetooth. |
| Helio G96 | Redmi Note 11S | 5.0 | No support for LE Audio. |
To find out your chipset:
- Open Settings → About the phone → Characteristics of the device.
- Find the processor or the SoC model.
- Check the table above.
If your model isn't on the list, check the specifications on Qualcomm's official website or Mediatek. For example, the Snapdragon 695 (in POCO X4 Pro) supports Bluetooth 5.1, although 5.0 may be displayed in the settings.
💡
On Qualcomm, type the name of the chipset into a search — the specifications will indicate the Bluetooth version. For Mediatek, use this page.
5. Check through ADB (for advanced users)
If none of the previous methods worked, the Android Debug Bridge (ADB) remains, and this method requires a computer, but gives a 100% accurate result.
What you need:
- 🖥️ Computer with ADB Tools.
- 📱 Included Debugging by USB on a smartphone (Settings) → The phone. → Version. MIUI — Tap 7 times, then return to the additional → For developers).
- 🔌 USB-TypeC Cable (preferably original).
Instructions:
- Connect the phone to the PC and confirm the debugging permission.
- Open the command line (Win) + R → cmd) and enter: adb shell dumpsys bluetooth_manager
- Find the output line getAdapterVersion or mAdapterVersion.
Example of output for Xiaomi 12T Pro:
mAdapterVersion: 5.3 (LE)⚠️ Attention: On some firmware MIUI The dumpsys command can be blocked. Alternative command: adb shell settings get global bluetooth_version But it doesn't work on all devices.
Enable debugging on USB|Install drivers ADB PC-only|Connect your phone to the original cable|Run the command line on behalf of the administrator-->
Verification by smartphone model (official data)
If you're too lazy to dig into the settings, use Xiaomi's database. Each model has a fixed version of Bluetooth that depends on the chipset. Here's a quick guide to popular devices:
| Model | Chipset | Bluetooth | Features |
|---|---|---|---|
| Xiaomi 13 Pro | Snapdragon 8 Gen 2 | 5.3 | Support for LE Audio and LC3. |
| POCO F4 GT | Snapdragon 8 Gen 1 | 5.2 | The maximum range is 200 m (in theory). |
| Redmi Note 12 Pro+ | Dimensity 1080 | 5.2 | Problems with aptX HD on some firmware. |
| Xiaomi 11T Pro | Snapdragon 888 | 5.2 | Support for dual Bluetooth (2 devices at the same time) |
| Redmi 10C | Snapdragon 680 | 5.0 | No support for LE Audio. |
The full list can be found on Xiaomi’s website (Specifications for each model) or on GSMArena.Please note: sometimes the specs indicate the maximum possible version, but the real version may be lower due to firmware limitations.
💡
If the site says Bluetooth 5.1 and the phone's settings say 5.0, it's not always a mistake.
7. Definition of supported codecs
The Bluetooth version has a direct impact on the audio codecs available, and if your smartphone supports modern formats, then the module is not older than a certain generation:
- 🎵 SBC — Basic codec, works on all versions.
- 🎧 AAC — Bluetooth 4.0 requires+.
- 🔊 aptX - version 4.0 is needed+, but it's 5.0.+.
- 🎶 aptX HD — Bluetooth 5.0 only+.
- 🆕 LC3 — Bluetooth 5.2 requires+ (standard LE Audio).
How to check supported codecs:
- Connect Bluetooth headphones with support for aptX or LDAC.
- Open Settings → Sound → Bluetooth audio quality.
- If you have aptX Adaptive or LDAC, your Bluetooth is no older than 5.0.
On Xiaomi with Bluetooth 5.2+, this menu should have a LE Audio or LC3 option. If it is not available, but the chipset supports (for example, Snapdragon 888), then the firmware is outdated.
