Owners of Xiaomi Redmi 8 smartphones often encounter intrusive sound when connecting a power cable. Standard MIUI settings require notifying the user when charging using a characteristic melodic signal. For some, it is a useful feature to control contact in the connector, for others – a source of irritation, especially at night or in quiet rooms.
Unfortunately, the standard Xiaomi Redmi 8 audio settings menu lacks a separate slider that would allow you to turn off the charger’s connection sound only while retaining the system sounds of the interface, which creates the illusion that you can’t solve the problem without obtaining root rights. However, there are several effective methods to circumvent this limitation with the regular Android operating system.
In this article, we will discuss in detail all the available ways to eliminate the sound notification, we will look at both simple changes in the sound profile and more complex manipulations of the engineering menu if the standard methods are not effective enough for your version of the firmware.
Standard sound settings and profiles
The first step in solving the problem is to carefully check the basic settings of the audio profile. The MIUI system installed on the Xiaomi Redmi 8 groupes different types of notifications, and sometimes the charging sound can be tied to the overall volume level of the system effects. You need to go to Settings → Sound and vibration and carefully study the available options.
Often users don't notice that the vibration mode or silent mode is activated, but when the power is connected, the phone still makes a sound. This is because the charger connection event in some versions of the firmware is classified as a high-value system warning. Try switching the sound profile to "No Sound" and check the device's response.
If a simple profile switch doesn't work, you should pay attention to the detailed volume settings. By clicking on the volume button and selecting three dots or a gear, you will be taken to the extended menu. Here, it's important to make sure that the "System Sounds" or "Other Sounds" slider is kept to a minimum, although this can affect the locking sound of the screen.
⚠️ Warning: Disabling system sounds completely can cause you to stop hearing screen lock or password error, which reduces the user experience.
Use of the "Do Not Disturb" mode
The most effective standard method for temporarily or permanently turning off the charging sound is to use the Do Not Disturb mode. Unlike the usual silent mode, this profile allows you to more flexibly adjust the exceptions and rules of behavior of the smartphone. For the Xiaomi Redmi 8, this often becomes the only working solution without installing third-party software.
To set this mode, go to Settings → Sound and Vibration → Do Not Disturb. You need to activate the function and go to additional settings of the schedule or rules. The key is to prevent the playback of any sounds other than calls from favorite contacts. In this mode, the event of the charger connection is often ignored by the audio system.
You can set up automatic Do Not Disturb mode when you connect the charger, although in stock MIUI, this trigger connection is not always implemented in a straight line, and most often users simply leave this mode on at night, which solves the problem of nighttime sound signals.
☑️ Setting up the "Do Not Disturb" mode»
It's important to understand the difference between modes. A normal silent mode can only block incoming calls and messages, leaving system sounds active. Do Not Disturb mode operates at a deeper level of notification priorities, suppressing most interruptions, including interface and peripheral events.
Configure through the menu of special features
In the arsenal of the Android operating system, which runs Xiaomi Redmi 8, there is a section "Special features" that hides features designed for people with hearing or vision impairments, but they can be useful in our case. Some audio profiles in this section can redefine the standard behavior of the sound card.
It is worth checking the Settings section → Advanced settings → Special facilities → If in your version MIUI If you have a "monoaudio" or "balance of sound" option, try playing with these settings. Although they don't directly turn off the charging sound, changing the audio stream sometimes causes the system sample to simply not play due to a conflict of channel priorities.
Also in the special features section is often the "Hear the screen" or TalkBack function. Activation and subsequent deactivation of these services can reset the cache of audio settings, which in rare cases helps if the charging sound was played due to a software error or "stick" of the audio driver.

Automating tasks with applications
If the Xiaomi Redmi 8’s built-in tools don’t work, automation apps come to the rescue. MacroDroid or its Tasker counterpart is the most popular and powerful tool, and these programs allow you to create scenarios that respond to system events, such as power connections.
The idea is to create a macro: "If power is connected → Set No Sound mode." After a few seconds, when the charging has already started, you can automatically return the sound profile to its original state. For the user, this process will occur instantly and imperceptibly, and the charging sound will simply not have time to play or will be cropped.
To implement this method, perform the following actions:
- 📲 Download MacroDroid from Google Play Store.
- ⚡ Click “Add macros” and select the trigger “Power connected».
- 🔇 In action, select "Sound Mode» → «No sound».
- ⏱ Add a 2-second delay and the action "Sound Mode» → «Normal».
Using third-party automatizers gives you flexibility not available in standard firmware, you can customize different reactions for different scenarios, for example, turn on vibration instead of sound only during the day, and at night completely turn off any notifications when charging.
System table of sound events
Understanding how Android handles sounds will help you better navigate your settings. Below is a table describing the main types of audio events in the system and their dependence on sound profiles, as exemplified by the Xiaomi Redmi 8.
| Type of event | Profile dependency | You can turn it off separately. | Impact on charging |
|---|---|---|---|
| Media | Independent slider | Yes. | No. |
| Alarm clock | Always sounds. | No. | No. |
| Systemic sounds | Depends on the settings. | Partially. | Yes (basic) |
| Notifications | Depends on the profile. | Yes. | No. |
| Touch sounds | Sound settings | Yes. | No. |
As you can see from the table, the charging sound is most often classified as system sounds, which is why simply turning down the volume of media files does not solve the problem, you need to influence the system channel or use the software profile switching described above.
In some custom firmware or after obtaining superuser rights, you can edit the system files responsible for linking sounds to events. However, for an ordinary user of Xiaomi Redmi 8, this carries the risk of losing warranty and possible “bricking” of the device, so this method is not considered as recommended in the article.
💡
If you use a third-party theme, try changing it to a standard one. Some themes may contain altered audio files or conflict with audio system settings, causing incorrect charging behavior.
Frequently encountered problems and solutions
Even after you have done all the settings, users may find that the sound is coming back, which may be due to a MIUI update that resets the user settings, or an application conflict. If the charging sound comes on suddenly after the update, check the settings again.
Another reason could be a malfunction of the USB Type-C or Micro-USB charging connector itself (depending on the Redmi 8 modification). If the contact is poor, the phone can constantly reconnect, making a new sound every time, in which case the software methods are powerless, you need to clean the connector or replace it.
Also worth mentioning is the Accessories Connect Sound feature, which is put in a separate menu in some regions and firmware versions. Check the Settings path → Advanced Settings → Accessories Sound. If you have one, just uncheck it. It's the most direct way, but unfortunately, it's not available in all software builds.
⚠️ Warning: If the charging sound is accompanied by a vibration that you also want to turn off, be sure to remove the “Vibration When Connected” tick from the same menu, if available, or use the “Do Not Disturb” mode».
Concluding recommendations
To sum up, the most reliable way to turn off charging sound on the Xiaomi Redmi 8 is to combine Do Not Disturb mode with proper system audio tuning. If these methods don’t work, using the MacroDroid automator app is a guaranteed solution.
Remember that the software is constantly updated, and the menu layout may change slightly in new versions of MIUI. Always check the relevance of the paths in the menu after a major system update. Careful attitude to the sound settings will make using the smartphone more comfortable.
💡
Using MacroDroid automation is the most flexible way to control charging sound, allowing you to create complex scenarios that are not available in standard Android settings.
Don’t be afraid to experiment with audio profile settings. Understanding the logic of your system is the key to complete control of your device. Importantly, the charging sound on the Xiaomi Redmi 8 is software-related to system notifications, so it can only be completely turned off through system noise suppression or automation.
