HD icon on Xiaomi phone: decryption, causes and ways to eliminate

Why is the HD icon on Xiaomi and what does it mean?

If you see a small HD icon in your Xiaomi status bar on your screen, don't panic -- it's not a system bug or a virus. It signals the High Definition Audio that's activated automatically when you plug in your headphones, speakers, or when you make phone calls. But for many users, it's always on, even without connected devices -- and that's a reason to figure out why.

HD Audio was first introduced in MIUI 12 firmware and has become standard for all subsequent versions. The developers wanted it to improve the quality of sound playback through hardware optimization. But in practice, users are faced with the fact that the icon does not disappear after the headphones are turned off, and sometimes even affects battery autonomy — especially on budget models like the Redmi Note 10 or POCO M4 Pro. In this article, we will discuss in detail what lies behind this icon, why it can burn for no reason and how to remove it once and for all.

Official decoding of the HD icon on Xiaomi

According to Xiaomi’s documentation, the HD icon in the status bar indicates the operation of one of three modes:

• 🎧 HD Audio for headphones – activated when connecting wired or Bluetooth headphones with support for high-quality sound (aptX codecs, LDAC, AAC).
• 📞 HD Voice for calls – turn on while talking on the network 4G/5G (VoLTE technology or VoNR).
• 🔊 HD Output for speakers – optimizes sound when played through built-in speakers (not available on all models).

Ideally, the indicator should automatically go out after the call is completed or the headphones are turned off. If this does not happen, the problem lies either in a system failure or in the forced activation of the mode through hidden settings. For example, on Xiaomi 12T or Redmi K50, users often find that the icon remains active due to a bug in the Bluetooth or Telephony module.

Reasons for the permanent display of the HD icon

If the HD indicator doesn’t disappear even after the phone is restarted, check the following points:

1. Active Bluetooth profile. Sometimes the system forgets to turn off HD Audio mode after the headphone connection is broken. Try manually deactivating Bluetooth in the settings.
2. Calling by VoLTE/VoNR. If your operator supports you HD Voice, the icon may burn until the session is over (sometimes required until the end of the communication session). 5 minute).
3. The com.android.phone service is a failure, and this system process is responsible for telephony, and its errors often lead to the sticking of indicators.
4. Custom firmware or modified cores: On devices with MIUI EU, Pixel Experience or other unofficial builds, the feature may not work properly.

On some models (for example, Xiaomi 11 Lite NE 5G), the problem is related to a hardware feature – the Qualcomm Snapdragon chip can force HD Audio to be activated for internal speakers, even if you do not notice it, in which case you can only turn off the icon through the engineering menu.

💡

Before you go through the settings, check to see if the HD icon only burns in certain apps (like YouTube or Spotify), some programs that activate high-quality audio via the Android API.

How to remove the HD icon on Xiaomi: step-by-step methods

How to remove an indicator depends on the reason it appears, start with the simplest solutions and move on to the complex ones only if the previous ones didn't work.

Method 1: Reset and reset sound settings

Restart your phone (hold the power button for 10 seconds)

Turn off and turn Bluetooth back on in Settings → Connections

Check active calls (sometimes a VoLTE session “hangs”)

Reset the sound settings to Settings → Sound → Reset-->

Method 2: Disabling HD Audio in the settings

Some models (Redmi Note 11 Pro+, Xiaomi 13) have a separate switch for this feature:

1. Open the settings → Sound → Sound quality.
2. Find the HD Audio option or High Sound Quality.
3. Turn off the slider and restart the device.

Method 3: Network reset (for VoLTE/VoNR)

If the icon only appears during calls, the problem may be in the settings of the mobile network:

1. Go to Settings. → SIM-maps and mobile networks.
2. Choose yours. SIM-map → Resetting network settings.
3. After the reboot, check if the icon has disappeared.

Method 4: Engineering menu (for power users)

If the standard methods didn't work, you can try to turn off the indicator through hidden settings.

Instructions for Qualcomm devices:

1. Open the phone app and enter the code: ##4636##
2. Go to the tab Information about the phone.
3. Scroll down and find the Set Audio HD (or similar) item.
4. Select Disable and save the changes.

For MediaTek chips, the code may differ:

##36446337##

Hardware Testing → Audio

💡

On devices with MIUI 14 and later, the engineering menu can be blocked, in which case only resetting to factory settings or firmware via Fastboot will help.

Xiaomi models, which are most often lit by the HD icon

Analysis of user reviews shows that the problem is most common on the following devices:

On flagship models (Xiaomi 13 Ultra, Mix Fold 3), the problem is less common due to more stable firmware, but on budget models (Redmi A1, POCO C50), the icon can burn constantly due to the savings in resources for software optimization.

Does the HD icon affect the phone?

The HD indicator itself does not load the system and does not consume an additional battery.

⚠️ Attention: On devices with MIUI 12.5 and older, permanent activation HD Audio can lead to an increase in charge consumption by 5-10% due to the operation of additional DSP-a processor (digital signal processor) that optimizes sound.

• 🔋 Battery: On Redmi 9A or POCO M3 with weak processors (Helio) G25/G80) The system can reduce the time of autonomous operation on 1–2 hour.
• 🎵 Sound quality: In some cases, forced on HD Audio for speakers leads to distortion at high volumes.
• 📶 Network: With active VoLTE, mobile internet speeds may deteriorate (especially on congested towers).

If you don’t use high-quality headphones or call VoLTE, turning off the mode will not only remove the annoying icon, but also slightly extend battery life.

Frequent mistakes when trying to remove the HD icon

Users often make the following mistakes when trying to get rid of the indicator:

1. Delete system applications: Some people try to disable the icon by removing com.android.phone or com.miui.player through ADB, resulting in loss of call or music functionality.
2. Resetting to factory settings without backup. It's a last resort, and without backup, you'll lose all the data.
3. Using "optimizers." Apps like Clean Master or DU Speed Booster not only don't help, but they can make the problem worse.
4. A rollback to the older version of MIUI. On some devices (such as the Xiaomi 12S), this results in a bootloader lock.

⚠️ Note: If you choose to use ADB To disable the icon, never enter commands such as pm uninstall -k --user 0 com.android.phone is going to completely break the phone. Instead, use secure commands like settings put global. audio_hd_enabled 0
