Owners of Xiaomi, Redmi and POCO smartphones often face situations where the device loudly alerts them to a power connection.This beep, built into the MIUI shell or the new HyperOS, can be useful for controlling connectivity, but at night or in quiet places it becomes an annoyance. Unfortunately, there is no slider in the standard volume settings menu that completely disables the system charging sound.
Many users mistakenly believe that the problem is solved by putting the smartphone in silent mode, but this is only part of the solution that does not always work correctly. Android and its modifications from the Chinese manufacturer are designed so that the power connection event is considered an important system notification. To effectively deactivate this sound, you need to apply a comprehensive approach that affects notification settings, operating modes and, in some cases, system parameters.
In this article, we will discuss all the known ways to make the charging process silent. We will look at the standard methods available to each user, and also touch on the deeper settings that will help you customize Xiaomi for yourself. It is important to understand that the interface may vary slightly depending on the version of the operating system.
Why Smartphones Make Sound When Connecting a Cable
The audio accompaniment of the charging process is not a bug, but a feature laid down by engineers for feedback. When you insert a USB cable into the connector, the power controller detects the voltage and sends a signal to the operating system. In response, Android generates a system audio file. On Redmi and POCO devices, this sound is often louder than on pure Android, due to the aggressive notification policy of MIUI.
To make matters worse, the sound is classified by the system as a system event, rather than media content or a call. That is why adjusting the volume of music through the side buttons often does not affect the volume of the welcome charging signal. The shell logic suggests that the user should hear the connection confirmation, especially if the cable or port has contact defects.
But in modern firmware versions, algorithms have become smarter, so if a smartphone is in Do Not Disturb mode or flipped down, the sound may not play, and understanding this logic chain allows us to find workarounds to achieve silence without losing the functionality of the device.
β οΈ Warning: Disabling system sounds completely through special applications may cause you to stop hearing other important system notifications.Be careful when installing third-party audio management software.
Set-up of sound and vibration modes
The first and most obvious step is to check current sound profiles, and in the MIUI shell, audio profile management is placed in a separate menu, accessible through the notification curtain or settings. Go to Settings β Sound and Vibration. Here you need to pay attention to the current active profile.
If you have the maximum volume Sound mode on, the system signals will play back at full strength. Switching to No Sound or Vibration mode often solves the problem, but it also turns off incoming calls. A finer setup is available in the Sound and Vibration Settings menu. Find the Additional Settings (if available in your version of MIUI) and check if there is a System Sound check box.
It is also worth checking the vibration settings. Often the charging sound is accompanied by a short vibration response. If your goal is complete silence and no tactile sensations, make sure that the Settings menu β Sound and vibration β Vibration switches off the effects when touching and entering, although this does not directly affect the charging sound, but creates a general acoustic background.
βοΈ Checking the sound settings
Importantly, on different versions of HyperOS, the location of the sliders can vary. In some cases, the volume of the system sounds is combined with the volume of the alarm or ringtone. Experiment with reducing these parameters to find the optimal balance.
Use of the "Do Not Disturb" mode
Do Not Disturb is the most effective tool in the system to block unwanted sounds, including charging sounds. Unlike normal silent mode, it allows you to flexibly adjust exceptions. To activate it, swipe down from the top of the screen to open the control center, and click on the icon with the month.
However, just turn on the mode is not enough. You need to go to its settings along the way Settings β Sound and vibration β Do not disturb. Here you should pay attention to the section "Behavior." Make sure that you prohibit the sounds of events. In some versions of MIUI there is a separate "System Sounds" switch inside the Do Not Disturb settings, which you need to deactivate.
The feature of this mode on Xiaomi is the ability to adjust the schedule, you can set the automatic turn on "Do Not Disturb" at night (for example, from 23:00 to 07:00), which ensures that at night the phone will not beep with every accidental touch of the charging cable.
| Parameter | Sound mode. | Vibration mode | Don't disturb mode. |
|---|---|---|---|
| Sound of charge | There is. | No (usually) | No. |
| Incoming calls | There is. | Vibration. | Locked down* |
| Notification of annexes | There is. | Vibration. | Locked down. |
| Alarm clock | It's working. | It's working. | It works (by default) |
*In Do Not Disturb mode, you can configure exceptions for selected contacts to avoid missing an important call.
Using this mode is a trade-off between silence and accessibility, and if you want your phone to be silent when charging, but you don't want to miss calls from loved ones, set up the "Do Not Disturb" menu exceptions, which will only block system sounds, leaving the channels open.
Disabling the sounds of the MIUI interface
In the back of the system settings, there are hidden parameters that are responsible for the voice of user actions. Although there is no direct "Charge Sound" switch, disabling related functions can help. Go to Settings β Sound and Vibration β Additional settings (the path may differ depending on the model, for example, Redmi Note or POCO F).
Find "Touch sounds" or "Lock sounds." Disabling these options makes the interface quieter. Some users note that once the screen lock sounds are turned off, the sound accompanying the battery icon appears when the power is connected disappears, which is because the charging event often triggers the animation and blocker sound.
It's also worth checking the theme settings. Third-party themes with MIUI can have their own sound packages that replace standard system sounds. If you've recently changed the design, try going back to the standard theme "Classic" or "Standard" to see if the intrusive sound disappears.
The impact of design themes on sound
Remember that system updates can return resets. After a major update to HyperOS or MIUI, it makes sense to recheck these points, as the priorities of sound streams may have changed by developers.
Resetting sound settings through the engineering menu
For advanced users who are confident in their actions, there is an option to reset audio profiles, which is not a complete reset of the phone, but only a return of the sound settings to factory values, which can help if the charging sound appeared after some kind of failure or installation of a conflicting application.
You will need to open the Phone app and enter a special code. However, newer versions of Android have closed the engineering menu, and codes like ##6484## (CIT) may not open the full audio settings. However, enter the code ##3646633## (powered by MediaTek processors) or use the Play Market's Engineer Mode app for Snapdragon devices.
If you can get into the engineering menu:
- πΉ Go to the Hardware Testing or Audio tab.
- πΉ Find the Audio Debugging section.
- πΉ Try to find a Reset option or check the volume levels for system events.
Be very careful: changing unknown parameters in the engineering menu can lead to the complete disappearance of sound in the phone, which will have to be restored by flashing.
A safer method is to reset special features. Sometimes the charging sound sticks because of errors in accessibility services. Go to Settings β Advanced Settings β Special features and check if there are active services that can interfere with the sound.
β οΈ Warning: Do not use third-party apps from the Play Market with names like "Volume Control" or "System Sound Enabler" without checking reviews. They may request excessive permissions and contain advertising, and their effectiveness on new versions of Android is questionable.
Third-party applications and automation
If the regular tools don't work, automation apps come to the rescue, and the way they work is that they track the Power Connection event and instantly put the phone into silent mode, and when they shut it down, they put the settings back in, which creates the illusion that the charging sound is off.
A popular tool is MacroDroid or Tasker. MacroDroid can create a macro: "Trigger: Power is connected" β "Action: Sound Mode (No Sound/Vibration)" This works more reliably than manual switching, since it happens automatically.
Another approach is to use equalizer apps that have system sound management. However, starting with Android 10 and up, Google has restricted apps' access to the system sound stream, so older methods may not work on the Redmi Note 12 or more newer models.

Use the Digital Well-being app to create Sleep mode, which allows you to set up automatic shutdown of system sounds and schedule notifications to solve the problem of night charging.
Automation via IFTTT or built-in scripts in MIUI (if your version supports "Scenarios" in the "Security" or "Conductor") is another option. You can create a script: "If it's 23:00 to 07:00 and the phone is charging β Enable Flight Mode or No Sound."
