Every time you connect your smartphone to a power source, the usual system sound is heard. For many users of Xiaomi, Redmi and POCO devices, this signal becomes intrusive, especially if the device is charging at night or in a quiet office. A standard tune can seem too loud or just annoying, and the desire to replace it with something more pleasant or completely turn off arises in most owners.
Fortunately, MIUI and its modern version of HyperOS provide flexible personalization tools that not only turn off the audio of the connection completely, but also replace it with any audio file in your collection. In this article, we will discuss in detail all the available ways to manage audio notifications when charging, from standard settings to using the themes of the design.
It’s important to understand that the menu interface may vary slightly depending on the firmware version and model of your gadget. However, the logic of the system remains the same for the entire ecosystem of the brand. We will look at the algorithms of actions that are relevant for both the budget models of the Redmi Note series and the flagship Xiaomi 13 or 14 series.
Standard settings of sound notifications of the system
The first and most obvious way to control sounds is to go to the basic operating system settings. In the Xiaomi shell, the path to the desired parameters may not be hidden in an obvious place, like in "pure" Android. You will need to go to the Settings menu, then select the Sound and Vibration section, and this is where the main volume sliders and melodies selection are concentrated.
Inside this section, look for the Advanced Settings or search for System Sounds category right away. In some versions of MIUI, this switch is at the bottom of the list of basic audio settings. When you click on it, you'll see a list of all system events that may be accompanied by an audio signal: locking the screen, touching the keyboard, and of course, connecting the charger.
Here you can simply move the slider opposite the Charging item to the inactive position if you want silence. If your goal is to replace the melody, you can't always do that with standard means, because MIUI often tightly ties system sounds to the chosen theme. However, new versions of HyperOS have the ability to select standard sounds from the list without changing the whole theme.
💡
If the charging sound slider is not on the menu, try switching the sound mode from No Sound to Sound, as in quiet mode, system confirmations are often blocked automatically.
And the thing to note is that the changes are instantaneous, and you just have to take the cable out and plug it back in to see if you're not comfortable with the standard set of sounds, and then you go to more advanced customization methods that allow you to use your own customization. mp3-file.
Using the Themes app to change the melody
The most effective way to change the charging sound to a particular track is to use the built-in Themes app. This is Xiaomi's standard tool that allows you to deeply modify the interface, including graphic elements and soundtracks. You don't need to be a designer or programmer to use this method.
Open the Topics app on your device. At the bottom of the screen, look for a profile icon (usually a person or avatar image). Going to the profile, you will see My Pages or My Topics, which stores all the designs you uploaded, as well as the standard themes preinstalled by the manufacturer.
Choose any theme you like visually, or use the standard Classic theme if you don't want to change the wallpaper and icons. Click Apply. After you use the theme, the system will suggest customizing its components. Select Sound or Ringtone. In the list that opens, you can choose the charging melody from the suggested ones or add your own from the phone's memory.
☑️ Checking before changing the topic
Once you select the right track, the system will only apply the sound package of the chosen theme, leaving the wallpaper and icons unchanged (in most cases), which allows you to create a unique configuration where the visual style remains familiar and the sound design is fully personalized to your preferences.
Creating a custom theme with your own sound
If standard themes don't contain the sound you want, or if you want to use a particular snippet of your favorite song, you'll have to create a minimalist theme. This may seem complicated, but in practice, the process takes no more than 10 minutes. You'll need a computer or a smartphone with a file manager.
The idea is to take a simple theme, unpack it, replace the charging audio file with your own and pack it back. charge_start.mp3 Or it has a similar name inside the theme archive. You can find ready-made theme templates on Xiaomi fan forums.
To replace the file on the phone itself, you can use file managers with support for working with archives, such as ZArchiver. Find a folder with a theme, open it as an archive, find a folder sounds or audio and replace the existing charging file with your own, renaming it the original name.
⚠️ Warning: When editing system theme files, always back up the original theme. An error in the archive structure or audio file format may cause the theme to fail or not work properly.
This method gives you complete freedom of creativity. You can make the charging sound a quiet whisper, a cheerful signal or even a voice message, the main thing is to follow the file format (usually MP3 or OGG) and duration (no more than 5-7 seconds for performance).
Setting up scenarios and automation
For users who like full control of the device, a great solution is to use embedded scripts or third-party automation applications such as MacroDroid or Tasker. MIUI has a built-in Scripts (or Automation) application that allows you to create chains of action.
You can create a script that will work when you have a Power Connected event, and you can choose "Play Sound" as your action, and you can specify any file from memory, and the advantage of this method is flexibility: for example, one tune can play during the day, and a silent vibration can be activated at night.
To create this scenario, go to Tools → Scripts. Press the add new script button. As a condition (If) select Charge → Start Charging. As an action (To), select Multimedia → Play Sound. Here you can select a file from the list.
| Setup parameter | Standard method | Through the Topics app | Scenarios (Automation) |
|---|---|---|---|
| Difficulty | Low. | Medium | Tall. |
| Flexibility of sound selection | Only systemic. | Any MP3. | Any file + conditions |
| Impact on the system | Absent. | Minimum | Requires background work |
| Schedule capability | No. | No. | Yeah (day/night) |
Automation is especially useful if you want the sound of charging to change depending on the context, like silence at work and a fun tune at home, which makes interacting with your smartphone more intelligent and convenient.
Solving problems with lack of sound
Sometimes users have the opposite problem: they want to hear the connection sound, but they don't. This can be caused by several factors. First, check whether the mode is "Do Not Disturb" or "No Sound" In this mode, Android prioritizes blocking system sounds, even if the slider is on.
Second, make sure the theme file you're using isn't corrupted. If you've recently changed design, try going back to a standard Xiaomi theme and checking if sound has emerged. Often third-party themes downloaded from unverified sources may not contain a full set of audio files.
⚠️ Warning: If the sound is gone after the system update, check the application access settings. Sometimes, after the update, permissions are reset for system services responsible for playing media events.
It's also worth checking the connection of headphones or Bluetooth devices. If wireless headphones are connected to the phone when you charge, the sound can be played in them, rather than through the smartphone speaker. Turn off Bluetooth for verification.

Features of work in HyperOS mode
With the release of the new HyperOS shell, which gradually replaces MIUI on new Xiaomi 14, Redmi Note 13 and others, the structure of the audio menu has changed, now the management of audio profiles is taken to a more prominent place, and the system itself has become more modular.
HyperOS has introduced the Sound Effects feature, where you can not only change the tunes, but also adjust their spatial sound (if supported by speakers). When you connect the charger, you can now display more beautiful animations, which can also be accompanied by a sound that depends on the selected "Showcase" (Always On Display).
Users should look at the Personalization in Settings section, which brings together all the tools to change the look and sound in one place, making it easier to find the right setting, making it more logical for a new user who may have previously been entangled in the wilds of the MIUI menu.

The most reliable way to get the desired sound is to install a finished theme from the directory that already contains the desired melody, which eliminates the risk of errors when manually editing files.
In conclusion, managing the charging sound on Xiaomi devices is a simple process that makes it easier to use your smartphone. Whether it’s completely turning off annoying squeak or setting up your favorite tune, you can always tailor the device to your needs using the built-in tools of the system.
