How to turn off the sound when charging Xiaomi Redmi

Many Xiaomi and Redmi smartphone owners face a situation where connecting a device to a power source is accompanied by a loud system sound. This can be extremely inconvenient, especially at night when you put your gadget on charging before bed and a sharp signal breaks the silence or wakes up the household. In the shells of MIUI and the new HyperOS, developers have provided several ways to control audio notifications, but it is not always obvious to hide the sound of the start of charging.

The problem is that the standard settings menu doesn’t always have a direct Charging Sound switch, often tied to the system’s lock-screen or security notification sounds. Understanding the alert structure in Android allows you to find workarounds and set the device up to charge silently. In this article, we’ll look at all the available methods, from simple volume settings to using special modes.

It’s worth noting that the behavior of the system can vary depending on the firmware version and model of your smartphone. On older versions of Android, charging sound was often part of the system sounds that could not be turned off individually without root rights. However, modern versions of the MIUI 12, 13, 14 and HyperOS shell provide much more flexibility in managing audio profiles. We’ll look at current solutions that will help you make the charging process quiet.

Use of standard volume settings

The easiest and most affordable way to remove an annoying signal is to control the overall volume of system notifications. In most cases, the sound that Xiaomi makes when connecting the cable is classified by the system as a system notification or lock sound. To check this option, you need to go to the audio settings menu and reduce the corresponding slider to a minimum before connecting the charger.

However, this method has a significant disadvantage: by reducing the volume of system sounds, you can stop hearing other important notifications, such as alarm clocks or timer signals, if they are also tied to this channel.

Some firmware versions have the option of fine-tuning the volume for different types of events. If your smartphone supports Advanced Sound Settings, try to find a separate slider for system effects. Turning off vibration when charging is also often bundled with an audio signal, making this a dual-pronged solution.

• 🔊 Press the volume button and select the gear settings.
• 📉 Drop the “System Sounds” or “Notifications” slider to zero.
• 🔌 Connect the charger and check the result.
• 🔙 Return the volume to the previous level if the method works.

⚠️ Warning: Remember to return the volume level of system notifications after charging, otherwise you may miss important system alerts or alarms throughout the day.

Setting up the "Do Not Disturb" mode

The most effective regular tool to turn off all sounds at a certain time is Do Not Disturb, which is a mode in MIUI and HyperOS that has flexible settings to create schedules, and you can set it up automatically at night when you normally put your phone on charge, which will automatically drown out the connection sound.

To set up, go to the Sound and Vibration section and find the Do Not Disturb option, and it's important not just to turn on the mode, but to set the exceptions. Make sure that the exceptions are not marked in front of System Sounds or Locking Sounds, and if this option is available, turning it off ensures that even when you're active, Do Not Disturb, the phone will be completely quiet when you connect the power.

The advantage of this is that it's automated, you don't have to manually switch profiles every night, and the smartphone will know that it's time for silence, and when you plug in the charger, it won't make a sound, and this is especially true for users who charge devices in the bedroom or the nursery.

Application of automation scenarios

The MIUI shell has a powerful automation tool built in that is often overlooked, and with the Security app or the Scenarios app (depending on the firmware version), you can create a rule that changes the sound profile when you connect the charging, the most elegant solution that doesn't require third-party software.

To create this scenario, open the Security app, scroll down to the Battery section, or find a separate Scripts app. You need to create a new automatic script with the condition “When connecting the charger.” As an action, select “Sound Mode” and set the value “No Sound” or “Vibration.” You can also add a condition to turn off this mode when you turn off charging.

This approach allows you to keep the volume of notifications during the day at a high level, but automatically "muffle" the phone at the time you start charging, this eliminates the need to change the settings each time, and scripts can work even in sleep mode, providing complete silence.

⚠️ Note: When creating scripts, make sure that the Security or Scripts app has all the necessary permissions to change system settings, otherwise automation will not work.

Disabling the screen lock sounds

Often, the sound that the user perceives as “charging sound” is actually the sound of unlocking or locking the screen. When you plug in the phone, the screen lights up and the system can play the lock sound. At Xiaomi and Redmi, these sounds are often tied to the theme of the design, but they can be controlled through system settings.

To turn off, go to Settings → Sound and Vibration. Find Additional Sound Settings (may be called Advanced Settings). This often hides the Screen Lock Sound switch. Disabling this setting will make the screen on and off, as well as activating it when charging, silent.

If there is no such item in the standard menu, try changing the theme to a standard one ("Classic" or "Default"). Third-party themes from the MIUI Themes store often contain their own sound packages that can ignore the system settings of silence. The sound charging file in custom themes is often of high priority and can be played even in vibration mode.

Use of third-party applications

If MIUI's built-in tools don't seem flexible enough, you can always turn to third-party developers. There are many audio profile management apps on the Google Play Store, such as "Volume Control" or "Sound Profile," which allow you to create more complex rules than standard Xiaomi scripts.

However, be careful when installing these applications, which require extensive permissions to access the system, which can affect device autonomy or data security. Before installing, carefully read reviews and check the list of permissions requested. Often these applications run in the background, constantly monitoring the battery status.

An alternative is macro-building applications like MacroDroid or Tasker, which can write a script that says, "If battery is connected → Set media volume to 0 → In 2 seconds, turn volume back," which will allow you to hear a short notification (if necessary), but will immediately drown out music or video if they were turned on.

Specifics of work in HyperOS

With the release of the new HyperOS operating system, which replaces MIUI, the menu structure has changed somewhat. The approach has remained the same, but the names of items may differ. HyperOS has increased its emphasis on the ecosystem, so the audio settings can sync with other Xiaomi devices if the corresponding function is enabled.

Owners of HyperOS devices should pay attention to the “Sound Effects” section in the settings, there may be a separate switchboard for System Sounds, which includes charging sound, and the updated interface allows you to quickly switch audio profiles through the control center (curtain).

The key difference is that the new system is more aggressive with background processes. If you use a third-party app to turn off the sound, make sure that you have permission to “Start” and removed the restrictions on the background in the “Battery and performance” section, otherwise the system can “kill” the automation process immediately after the screen is turned off.

💡

If the charging sound appears after a firmware update, check the settings of a new theme design – often the update resets the theme to a standard, but saves the sound package from the old theme, causing conflicts.

The most reliable way to remove the sound is to create an automatic script in the Security app, which puts the phone into silent mode when you connect the cable.
