How to turn off the sound when setting for charging on Xiaomi

Daily use of Xiaomi’s smartphone is often accompanied by intrusive beeps that can be annoying in silence. Especially when you put the device on charge, and it loudly alerts you to the power connection. Owners of budget and flagship models face the same problem: standard audio settings do not always remove this particular signal. Understanding how to turn off the sound when setting up for charging will help restore comfort when using the gadget.

MIUI and the new HyperOS are designed to keep the user as informed as possible about battery status, but it is not always convenient. Sometimes a loud jing wakes up the household at night, and sometimes just distracts from work. In this article, we will discuss all the available ways to eliminate this sound, from simple menu switches to deeper system settings, which often remain hidden from the ordinary view.

It's important to understand that the algorithms for the sound engine can vary depending on the firmware version. What worked on MIUI 12 can be reworked into MIUI 14 or HyperOS. So we'll look at universal methods that cover most use cases, allowing you to choose the right option for your smartphone model.

Standard sound and vibration settings

The first step should always be to carefully research the standard settings menu, and many users skip the obvious options by relying on automated profiles, and you need to go to Settings and find Sound and Vibration, and that's where the main controls for your device's audio output are.

Inside this menu, you should carefully study the Additional settings subsection. In some versions of the Xiaomi shell, the option to turn off system sounds is displayed here. Note the interface sound switch. If it is active, the system will play sounds during any interaction, including connecting the charger.

But there's a caveat: Turning off the interface sounds can make the phone too dumb, by removing keyboard or locking sounds. You need to find a balance. Try turning off only system notifications, keeping the media sounds active, which will keep the functionality, but will remove the unnecessary signals.

• 🔊 Check the system sound volume slider – sometimes it’s enough to just minimize it without completely turning it off.
• 🔇 Make sure that no Do Not Disturb mode is activated with exceptions that system sounds may miss.
• 📱 Check the theme settings – some third-party themes may force sound effects.

⚠️ Warning: Disabling system sounds may cause you to miss important connection error notifications or low charge if the visual indication is also disabled.

Use of the "Do Not Disturb" mode

One of the most effective ways to remove the charging sound at night is to properly configure the Do Not Disturb mode, a tool designed to insulate the user from the noise, but it's much more than just blocking calls. In the Settings menu → Sound and vibration → Don't disturb you can set your schedule.

Set a time slot, for example, from 23:00 to 07:00. In the advanced settings of this mode, find the option "Notification Behavior" or "Visual Mode." Here you can set a rule that all system sounds, including the sound of the power connection, will be suppressed. This is the ideal solution for those who leave the phone to charge overnight.

You can also pay attention to the Auto Turn on feature, so you can set your smartphone to activate Do Not Disturb mode automatically when you charge, if you have such a trigger bundle (often found in automation scenarios) that will provide silence at the right time without you.

Remember that in Do Not Disturb mode, the screen may not light up when charging arrives, which can also be convenient.However, if you want to see the phone start charging, leave the visual indication on by turning off the audio channel only.

Hidden engineering menus and codes

For advanced users who are not satisfied with standard methods, there are engineering menus, accessed through the Phone application by entering special ones. USSD-One of the most popular codes for diagnosing and tuning sound is ##6484## (CIT menu or ##4636##.

V CIT menu (CIT Test) you can find a section related to audio tests. Although there may not be a direct button to turn off charging sound, checking the speakers and settings of audio channels sometimes reveals software failures that cause incorrect sound behavior. MIUI The #3646633## (Engineer Mode) menu allows you to control the logic of sound events.

#6484## - Enter the equipment testing menu
#4636## - Phone and battery information menu

Be very careful when using the engineering menu. Changing unknown parameters in the Audio or Hardware Testing section can lead to the complete disappearance of sound in the device. If you are not sure about your actions, it is better not to change the default values.

Theme settings and personalization

Intrusive sounds are often caused by set themes. In the Xiaomi ecosystem, themes can completely replace system sounds, including charging melodies. If you recently changed the theme and noticed the sound, this is probably the problem.

To check this out, go to the Themes app, click on the profile icon and select My Themes. Apply the standard Classic or Default theme. If the sound is gone, then the third-party theme has its own audio file for the charging event. You can either stay on the standard theme or find another one where that sound is missing or replaced with a quieter one.

Also, in the theme settings (if it supports deep customization), you can sometimes separately manage the sound effects. Look for System Sounds within the theme menu. There may be a separate slider or switch for system events such as locking, unlocking and plugging in the charger.

💡

If you like experimenting with themes, create or download a theme that has a file in it. charge_start.mp3 Replace it with a silence file and rename it accordingly before installation.

Automation through Scenarios

The most flexible and modern way to control smartphone behavior is through embedded scripting, with MIUI and HyperOS having a powerful automation application (often called “Scenarios” or integrated into “Conductor”/“Security”) that allows you to create chains of action: “If event A, do B.”

You can create a new scenario with the condition: "When the power is connected." As an action, select: "Enable Do Not Disturb" mode or "Establish a sound profile"; the second part of the scenario is to make the condition "When the power is turned off" and the action "Stop Do Not Disturb mode" so that the phone will automatically "numb" when charging starts and "come alive" after it ends.

The good thing about this method is that it doesn't require constant manual intervention and works regardless of the current volume you set for music or video. The system itself switches the context of the device's use depending on its state.

• ⚡ Create a “Night Charge” script to automatically turn on the quiet mode from 23:00 to 07:00.
• 🔋 Set up a scenario to turn off Wi-Fi or mobile network when charging if needed to save money.
• 🔔 Add vibration instead of sound in the script to physically feel the connection but not hear it.

⚠️ Note: Scenarios may not work if the automation application has been closed by the system to save energy. Add the Scenarios app to the battery exception list (launch and run in the background).

Third-party applications and Root rights

If Xiaomi's built-in tools fail to solve the problem, apps from the Google Play Store come to the rescue. There are utilities like Sound Assistant or various audio profile managers that can intercept system events, but their effectiveness depends on the Android version and access rights.

Root-righted users have unlimited options. File managers with access to the system partition (e.g., Root Explorer) can find the system audio files, usually along the /system/media/audio/ui/ path. The file responsible for charging is often called PowerOn.ogg or ChargingStarted.ogg.

By replacing this file with an empty audio file (or simply deleting it, although it is less secure), you are guaranteed to remove the sound at the system level. But remember: any interference with the system partition requires superuser rights and can lead to loss of warranty or unstable device operation.

💡

Root rights are a last resort: Before modifying system files, make sure to create a full backup of the data and make sure you know how to restore the device in the event of a crash.
