How to turn off the sound of the battery discharge Xiaomi: all ways

Owners of Xiaomi, Redmi and POCO smartphones often encounter an intrusive and loud beep that is activated when the battery is reduced to critical values. This system squeak, which is heard when it reaches 20% and 5%, is intended to alert the user, but in many situations it becomes an annoying factor, especially when hearing a sharp beep in the theater, at a meeting or during a night’s rest.

Unfortunately, with standard MIUI shells or the new HyperOS, it is not possible to completely turn off this system sound, as it is part of low-level security warnings. However, there are proven workarounds to silence this sound or change it to a less noticeable one. In this article, we will discuss effective methods for solving the problem.

We will discuss both the software settings and the use of third-party utilities that will help you get rid of unnecessary noise, and it is important to understand that by disabling the notification, you take responsibility for controlling the level of charge, so as not to be left with a discharged device at the wrong time.

Reasons for the appearance of sound notification

System discharge sound is not a bug, but a specially implemented feature of Android and shells based on it. Xiaomi developers implemented this mechanism to ensure that the user pays attention to the need to charge the device. The logic is simple: visual notification in the status bar may not be enough if the screen is off or the phone is lying down.

The sound is activated automatically when it reaches the thresholds that are hard-coded in the system files, usually in two stages: the first signal sounds at 20% charge, suggesting to turn on the power saving mode, and the second, more persistent, at 5%, warning about an imminent shutdown, the volume of this signal is often independent of the overall volume of the media, which makes it special.

Some users confuse this sound with app notifications, but if the sound is heard even when closed programs and a clean desktop, it is the Battery Saver system warning. Understanding the nature of this sound helps to choose the right method of blocking it.

⚠️ Warning: Ignoring discharge warnings may cause your phone to suddenly shut down at the time of an important call or loss of unsaved data.

Setting the volume of system notifications

The easiest way, though not always effective on all firmware versions, is to lower the volume of system notifications. Unlike the volume of music or a call, the Notifications or System Sounds setting directly affects the volume of interface alerts, including the battery signal.

To do this, you need to press the side button to increase or decrease volume. When a slider appears on the screen, click on the setting icon (usually three dots or a gear) to expand the menu, and here you will see several scales: media, bell, alarm and notifications.

Lower the notification slider to a minimum, which will make the system squeak barely audible or completely silent, while keeping the ringtone volume for incoming calls, a method that works normally and does not require the installation of additional software.

💡

If the Notifications slider doesn’t affect the sound of the battery, try also turning off the vibration sound in the same volume settings menu.

It is worth noting that after the device is restarted, the settings can reset, so this method requires periodic checks, but for many users this becomes a temporary but effective solution to the problem.

Use of "Do Not Disturb" regimes

The Do Not Disturb feature in Xiaomi smartphones has a wide range of sound filtering capabilities, and by activating this mode, you can prevent the playback of any sounds other than those added to exceptions, such as calls from favorite contacts.

To set up mode, go to Settings → Sound and vibration → Do not disturb. Here it is important to configure the settings correctly. Under Allow notifications or Sounds, you must uncheck all points except critical ones. The system sound of battery discharge is often classified as a normal system notification.

You can set this mode to automatically turn on on schedule, for example, set the activation from 23:00 to 07:00 so that the night squeak at 20% does not wake you up, this is the most civilized way to combat obsessiveness without deep interference with the system.

• 🌙 Total silence: The mode blocks all audio signals, including system.
• ⏰ Automation: The ability to set the exact time on and off mode.
• 📞 Favorites: Keeping the ability to hear calls from loved ones.
• 🔋 Visual control: The battery indicator will still show discharge, even without sound.

This mode is especially relevant in cinemas or business meetings, where no extraneous sound is allowed, but remember that in this mode you can miss other important notifications from messengers.

Application of third-party silencer applications

Since the standard methods to completely remove the system file sound can not be root-rights, come to the rescue specialized applications from Google Play. the most popular and effective solution is the utility Disable Low Battery Sound or its counterparts, such as No Low Battery Alarm.

The principle of such applications is to create a constant background process that monitors the level of charge. At the moment when the system tries to reproduce a standard sound warning file, the muffler application instantly reduces the volume of the media channel to zero or replaces the sound file with an empty one.

To work properly on MIUI and HyperOS, you need to give them advanced resolutions. The aggressively system kills background processes, so you need to lock the application in memory and remove battery restrictions.

Once set up, it becomes a subtle assistant, it doesn't require constant interaction, and it reliably prevents annoying squeaks from appearing, and it's the most radical software solution for those who don't want to get into system files.

Replacement of the system sound file

For advanced users who are ready for more complex manipulations, there is a method of replacing the sound file itself, which is responsible for the warning, which requires a file manager with access to system partitions, such as MT Manager or Root Explorer.

The low-charging warning sound file is usually located along the path /system/media/audio/ui/ or /system/media/audio/notifications/. The file may be called LowBattery.ogg, PowerOff.ogg, or have a similar name depending on the Android version.

The idea is to create an empty audio file in.ogg format and rename it to the system file name, and then, by replacing the original with an empty file, you will have the system "reproduce" silence when the event occurs.

⚠️ Warning: Root rights are often required to replace system files. Careless handling of system files can lead to unstable device operation or cyclical restart.

This is the most reliable method, because it eliminates the cause of sound at the file system level, rather than simply masking it, but it requires technical literacy and caution when dealing with root rights.

Comparison of methods of switching off sound

The right method depends on your technical background and goals. If you just need to survive a night or a movie, do not disturb mode is enough. To constantly solve the problem without installing extra software, adjust the volume of notifications will do. If you want to forget about the problem forever and do not fear difficulties, replacing the file or using silencers will be optimal.

The table below compares the main characteristics of the methods considered so that it is easier for you to choose the right option.

💡

The optimal balance between safety and efficiency for most users is to use specialized jammer apps from Google Play.
