How to turn off the audio of the connection to charging on Xiaomi: all the ways (including hidden)

The sound of charging on Xiaomi, Redmi and POCO smartphones can be annoying - especially at night when you plug your phone in silence. By default, MIUI plays a loud signal every time you connect the cable, even if the device is already charged or in silent mode. Fortunately, there are several ways to fix this, from standard settings to hidden engineering menu features.

In this article, we will discuss all the current methods of disabling charging sound on Xiaomi devices (including models from 2023-2026) running MIUI 12-14 and Android 11-14. You will learn how to remove sound through system settings, third-party applications or even physical modification of the firmware. Importantly, some methods require root rights or unlock the bootloader – we will warn about the risks in advance.

Why Xiaomi does not allow you to turn off the charging sound through standard settings?

The manufacturer intentionally limits the ability to turn off the charging connection sound for several reasons:

• 🔊 User feedback: signal confirms that the cable is connected correctly and charging has started. USB-C, where the connector is symmetrical, but can be inserted loosely.
• 🛡️ Protection against counterfeit accessories: Xiaomi uses sound as part of a notification system for uncertified chargers (for example, if the cable power is below the permissible limit).
• 📱 Unified user experience: the company aims to unify the interface across all devices, and turning off the sound could create confusion for beginners.

However, the latest versions of MIUI 14 have a hidden option to turn off the sound through the engineering menu – it is not in the public documentation, but it works on most models (except the budget series Redmi A and POCO M).

⚠️ Note: On some devices (e.g. Xiaomi) 13 Ultra or Redmi Note 12 Pro+) charging sound is rigidly spelled out in the system file /system/media/audio/ui/Charging.ogg. Disabling it without root rights can cause failures in other sound notifications.

Method 1: Disconnect via audio settings (works on 30% of devices)

The easiest method is to check if your version of MIUI has the option to turn off the charging sound in standard settings. Unfortunately, it is not available on all models, but it is worth trying:

1. Open the Settings app (cog icon).
2. Go to the section Sound and vibration.
3. Scroll down to the System Sounds block.
4. Look for the Charging Connection Sound or Charging Notice.
5. If there is a point, move the slider to the off position.

On most devices (e.g. Xiaomi 12T or POCO F5), this option is not available, so move on to the following methods, and if the item is present, but after the audio is turned off, it still plays back, then it is duplicated in another system file (more on this below).

Method 2: Use the engineering menu (#3646633##)

The hidden engineering menu (Engineer Mode) allows you to change the system settings that are not available in the normal interface. On some Xiaomi devices, you can turn off the charging sound through it:

1. Open the Phone app and enter the combination: ##3646633##.
2. If the code doesn't work, try ##4636##.
3. In the menu that opens, select the Hardware Testing tab (or Hardware Testing).
4. Go to the Audio section → Normal Mode.
5. Find Charging Sound or Power Connect Sound and set Disable.
6. Save the settings and restart the device.

This method works on devices with Qualcomm Snapdragon processors (for example, Xiaomi 11T Pro, POCO X4 Pro). On smartphones with MediaTek chips (for example, Redmi Note 12), the engineering menu may not contain the desired item.

Method 3: Disconnect via ADB (without root rights)

If standard methods don’t work, you can use Android Debug Bridge (ADB), a debugging tool that allows you to change system settings without obtaining root permissions, which is suitable for most Xiaomi devices on Android 10 and later.

You'll need:

• 🖥️ Computer with installed Xiaomi drivers and program ADB.
• 🔌 USB-cable (preferably original).
• ⚙️ Included debugging by USB on a smartphone (Settings) → The phone. → Version. MIUI → 7 times press to unlock the developer mode, then Settings → Additionally. → For developers → Debugging by USB).

Instructions:

1. Connect the phone to the PC and confirm the debugging permission.


2. Open the command prompt (Windows) or terminal (macOS/Linux) in the folder with ADB.




3. Enter the command:




adb shell settings put global charging_sound_enabled 0




4. Reset the device.

If the team doesn’t work, try an alternative:

adb shell settings put system charging_sound_enabled 0

⚠️ Note: On some devices (e.g. Xiaomi Mi) 11 Lite after use ADB The charging sound may turn off, but instead it will be a vibration. To remove it, additionally, perform: adb shell settings put global settings. charging_vibration_enabled 0

Method 4: Delete the system sound file (requires root)

If none of the previous methods worked, the radical solution is to delete or replace the system audio file responsible for the signal playback, which requires root rights and is only suitable for advanced users.

Instructions:

1. Install a file manager with root support (such as Root Explorer or Solid Explorer).
2. Go to /system/media/audio/ui/.
3. Find the files: Charging.ogg (main charging sound), PowerConnect.ogg (alternative), WirelessCharging.ogg (for wireless charging).

.bak

Charging.ogg.bak

Reset the device.

If you delete the sound, it's still playing, it's duplicated somewhere else.

• /system/media/audio/notifications/,
• /system/media/audio/alarms/,
• /vendor/media/audio/ (on some devices)

⚠️ Note: Deleting system files without backup can result in a cyclic reboot or loss of other sounds (alarm clock, notifications). TWRP Or OrangeFox Recovery.

💡

If you don't want to delete files permanently, you can replace them with an "empty" sound file. Download any silent.ogg file (such as from Zapsplat) and rename it to Charging.ogg, then upload it back to the system folder.

Method 5: Using third-party applications (without root)

If you don't want to dig into settings or risk firmware, you can use third-party apps that block the charging sound at the software level.

• 📱 MacroDroid – allows you to create macros that automatically turn off sound when you connect a charge. Example rule: Trigger: Connect charging, Action: Set the volume of notifications to 0%, Limit: Only when the screen is off..
• 🔇 SoundAssistant (from Samsung, but runs on Xiaomi) – gives extended control over system sounds, including charging sounds.
• 🛠️ Tasker is an advanced automation tool. To turn off sound, create a Media Volume task. → 0 at the Power Connected event.

The downside of this method is that applications need permissions to access notifications and special features, which can affect autonomy, and some programs (such as MacroDroid) require payment to unlock all features.

💡

Third-party apps are the safest way to go, but they can conflict with MIUI optimization. If you have lags after installation, add the app to the exclusion list (Settings → Battery → Battery Optimization).

Method 6: Flashing on custom firmware (for advanced)

If you're willing to take drastic measures, you can install custom firmware (like LineageOS, Pixel Experience, or ArrowOS) that has the charging sound turned off by default or is easily customizable, a method that works for devices with an unlocked bootloader.

Pros:

• ✅ Complete control of system sounds,
• ✅ No restrictions. MIUI,
• ✅ Possibility of fine tuning through Magisk modules.

Cons:

• ❌ Loss of guarantee,
• ❌ Risk of "bricking" of the device,
• ❌ Certain functions (e.g, IR Blaster or cameras may not work properly.

If you are considering this step, follow the instructions on the XDA Developers or 4PDA forums for your model.

• Pixel Experience is a pure Android with minimalist design.
• LineageOS is a stable, open source firmware,
• crdroid is the balance between productivity and customization.

Frequent problems and solutions

Even after the charging sound is turned off, users face unexpected difficulties, and here are the most common ones and how to solve them:

If none of these methods helped, check:

• 🔍 Are there third-party launchers (such as Nova Launcher or Hyperion) that can block system sounds.
• 🔊 Is not activated mode Do not disturb with exceptions for notifications.
• 📲 Does any application conflict with the system (check Settings) → Annexes → Permits → Special access).
