Many users of Xiaomi, Redmi and POCO smartphones face a situation where a sudden beep when connecting a charger causes discomfort, this is especially true at night or in quiet rooms, when a loud alert can disturb the peace. Standard settings of the MIUI shell or the new HyperOS do not always allow you to easily and quickly solve this problem through a regular menu.
In this article, we’ll look at all the possible ways to turn off the charging sound on your device.We’ll look at both the standard methods for setting up the system and more advanced options for power users who want to gain full control over their gadget’s behavior.
It’s worth noting that the interface and availability of features can vary depending on the version of the operating system, so it’s important to keep a close eye on menu items, which may vary slightly across different smartphone models.
Why Smartphone Makes Sounds When Connecting a Cable
The audio tracking of the charging process is a standard feature of the Android operating system, which was adapted by Xiaomi developers for their shells. The main purpose of such a notification is to inform the user about the successful start of the energy storage process. However, the implementation of this feature in MIUI is often redundant: in addition to standard sound, the phone can emit additional signals when a certain percentage of charge is reached.
System sounds can be annoying if you use your smartphone as an alarm clock or a media center in your bedroom, especially when the volume of the charging notification is not regulated by the media slider or the call, but depends on the overall level of system sounds, and understanding the nature of these signals helps you choose the right method to turn them off.
⚠️ Warning: Shutting down system sounds completely may cause you to miss important notifications about critically low battery or connection errors.
In addition, some smartphone models have hardware features in which the power controller initiates an audio signal regardless of the software settings, in which cases the software shutdown may be incomplete or require the use of special tools.
Disconnection through standard sound settings
The easiest and safest way to remove annoying sound is to use the built-in audio profile settings, which require no third-party software installation and are completely reversible, but it has one major drawback: other system notifications can also be disabled along with the charging sound.
To perform the settings, go to Settings, then select Sound and Vibration. In the menu that opens, you should find the Additional Settings or System Sounds section, and there are switches for various system events, including connecting the charger.
- 🔊 Find the “Charging Sound” switch and put it in an inactive position.
- 🔇 If there is no separate switch, try turning off System Sounds or Lock Sounds».
- 📱 On some versions of HyperOS, you need to press the gear next to the volume slider for detailed tuning.
- ⚙️ Check if no sound or no disturb mode is activated, which also affects playback.
It is important to understand that these items may differ from firmware to firmware, so if you don’t find the right switch right away, search for settings by typing “charging” or “system sound.”
If standard methods didn’t work, it’s possible that your charging sound is part of the theme, so you’ll need to change the theme to a standard one or choose a theme that doesn’t have a sound file for the event.
Use of Do Not Disturb and Sleep modes
An alternative solution that saves system sounds during the day and disables them at night is the use of automated modes. The MIUI and HyperOS shell implements a powerful task planning tool that can change the sound profile on a schedule.
You can set Do Not Disturb mode to activate automatically at night, and in this mode, most audible notifications, including charging sound, are blocked. To set up, go to Settings → Sound and Vibration → Do Not Disturb.
You can set a schedule for activation, for example, from 23:00 to 07:00, and it is also worth checking the exception settings to avoid missing important calls from contacts from the favorite list.
| Parameter of regime | Description of action | Effect on charging sound |
|---|---|---|
| Planned. | Automatic time-onsetting | Blocks the sound at a given time |
| Repeated calls | Passing a second call from one number | It does not affect system sounds. |
| Visual effects | Screen blinking at notifications | It can be used as a substitute for sound. |
| Allow notices | List of exclusion annexes | Systemic sounds are not usually on the list. |
The use of automation allows you to flexibly control the behavior of your smartphone without having to manually switch profiles every evening, which is especially convenient for users who put the phone on charge at the same time.
💡
Use the “Sleep Mode” feature in the Digital Well-being app to automatically turn on the “Do Not Disturb” mode and change the wallpaper when going to bed.
Setup through the “Themes” app
Often the cause of intrusive sound is not the system itself, but the set theme. Themes in the Xiaomi store may contain their own audio files for system events that replace standard sounds.
To check if a theme is the source of the problem, go to the Topic app. Click on the profile icon in the lower right corner and select the Topics section. If you have a third-party theme installed, try temporarily switching to a standard Classic or Default theme.
If the sound is gone after the theme change, it means the audio files were the problem, so you can continue using the standard theme or search for another one in the store, after reading the reviews about the presence of system sounds.
⚠️ Note: When you change the theme, all the audio settings can be reset to the values set by the theme's author.
Also, some themes have the option of customizing sounds separately, go to the settings of a particular theme (if this option is supported) and see if it is possible to turn off the sound effects of the interface.
Advanced Methods: ADB and System Commands
For users who aren’t afraid to work with USB debugging, there’s a more radical method of turning off the sound, which involves using a computer and an ADB (Android Debug Bridge) utility, which allows you to interact directly with system settings databases.
Before you start, you need to activate the developer mode. To do this, seven times click on the build number in the About Phone section. Then in the Additional → For developers menu, turn on Debugging over USB.
Connect your smartphone to your computer, install drivers and ADB. Open the command line on your PC and enter the following command to check the connection:
adb devicesOnce the connection is confirmed on the phone screen, you can try to change the system sound value. The command can look like this (the path may differ depending on the version of Android):
adb shell settings put system sound_effects_enabled 0This command turns off all the interface sound effects, including the charging sound. Be careful, because this is a global change. To get it back, replace 0 with 1.
What if the ADB can’t see the phone?
Third-party applications for sound management
If the built-in tools don’t work, Google Play Store apps come to the rescue, and there are many audio profile management tools that have more flexible settings than a standard Android.
Applications like Volume Control or Sound Assistant allow you to create separate volume profiles for different events, some of which can intercept a charging connection event and automatically reduce the volume of system notifications to zero.
- 📲 Volume Control: Allows you to create automation scenarios.
- 🔇 Mute Notification Sound: Specializes in turning off notification sounds on a schedule or event.
- ⚙️ MacroDroid: A powerful automation tool where you can create a macro: If power is connected → Set the system volume to 0».
Using these applications requires special permissions, including access over other windows and access to system settings, which can slightly increase battery consumption, but gives maximum control.
☑️ Checking before installing third-party software
Frequently encountered problems and their solution
Even after all the settings are done, the sound may be saved, this may be due to bugs in a particular firmware version or software conflict, in which case it is recommended to reset the sound settings to factory values or check for system updates.
Sometimes it's not the phone that makes the sound, but the connected device, like a Bluetooth headset or a car system, and check if the sound is being played through an external audio device, and also make sure that the charging socket is free of moisture or dust, which can cause the contacts to short and the sound signal to falsely fire.
⚠️ Warning: If the charging sound is accompanied by vibration of the body or heating in the connector area, immediately stop using the device and contact the service center.
In rare cases, cleaning the Settings app cache or resetting all settings to factory settings (without deleting personal data) can help, but the latter method should only be used as a last resort.
💡
If no software method has helped to remove the sound, the problem may lie in the hardware or damage to the speaker, which requires diagnosis by a specialist.
