How to change the charging sound on Xiaomi: a step-by-step guide

Many Xiaomi, Redmi and POCO smartphone owners are faced with the desire to personalize their device by making its response to the network unique. The standard system signal that we hear every time we insert a cable becomes familiar and even annoying over time. Fortunately, the MIUI shell and the new HyperOS provide ample opportunities for changing audio notifications, including system events.

Unlike many other manufacturers, the Chinese giant allows users to replace standard audio files with their own compositions, whether it is an excerpt from a favorite song or a funny sound effect. However, this process is not always obvious, since the standard audio settings menu often lacks direct buttons to select a file to charge.

Next, we’ll go through a few proven techniques that will allow you to change the sound of your charger connection.We’ll look at both standard ways through the theme store and more advanced methods for power users wanting complete control of their gadget.

Features of the sound system in MIUI and HyperOS

Understanding how Xiaomi’s operating system manages audio files is the first step to successful customization. Unlike the pure version of Android, where files are in open folders, the manufacturer’s shell strictly regulates access to system resources, this is done for the security and stability of the device, but creates certain difficulties for those who want to make changes.

The system divides sounds into several categories: call melodies, application notifications, system interface sounds, and event sounds (locking, unlocking, charging), which often require access to hidden partitions or the use of special theme designers. A standard file manager doesn’t always allow you to copy. MP3-file in the system folder and expect it to work without additional manipulation.

⚠️ Note: Attempting to directly replace system files in the root directory without superuser rights (Root) can lead to interface errors or data loss.

It is important to note that with the release of security updates by Google and Xiaomi itself, some loopholes for direct file replacement may close, which is why the method associated with creating or downloading a special theme remains the most relevant and safe way to change the charging sound on Xiaomi in 2026-2026.

Audio file preparation: requirements and formats

Before proceeding with the technical part of the replacement, you need to prepare the audio file itself. The system will not accept any arbitrary track, especially if it is too long or has an unsupported codec. The optimal format for system sounds is MP3 or WAV, as they provide the best compatibility with the audio subsystem of the smartphone.

The duration of the sound is also critical. The charging sound should not be long, otherwise it will be interrupted or superimposed on other system events.The ideal duration is 1 to 3 seconds. If you take a passage from a song, make sure it starts and ends smoothly, without sharp cliffs that may sound unpleasant.

💡

Use online services or audio editor apps to trim the track to the desired length and normalize the volume before installation.

You can use simple applications like MP3 Cutter or built-in voice recorder functions to edit, if they allow you to save files in the desired format. After preparing the file, you need to save it in the device's memory, preferably in the Downloads or Music folder, so that it is easy to find during the setup process.

• 🎵 File format: It is recommended to use MP3 with a bitrate of 128 kbit/s or higher for clean sound.
• ⏱️ Duration: The optimal audio file size is no more 5 seconds, ideally 2-3 seconds.
• 📂 Location: Save the file in an easily accessible folder so you don’t search for it long when selecting from the menu.

Method of installation through the application "Themes"

The most reliable and officially supported way to change the charging sound is using the standard Themes app. It is through this tool that Xiaomi allows you to embed custom sounds into the system. You do not need to be a designer or programmer, just find a ready-made theme designer or create your own in a few minutes.

First, open the Themes app on your smartphone. In the search box, type in the "Charge Sound" or "Charge Sound" query. You'll see a variety of themes, often called "Charge MP3," "Custom Charge Sound," or just "Sound." Select any high-ranking free theme and install it.

Once you apply the theme, the charging sound will change to the one in the theme, but our goal is to put your file. Without removing the theme, go to the user profile (the person icon in the corner) and select the Settings or My Pages section, and you need to find the item that adjusts the sounds within the theme, or use the Create Theme feature if you want to do it manually.

A simpler path that works in most versions of MIUI: After installing a theme (such as “Make your own ringtone” or similar), go to Settings → Sound and vibration → Notifications. Sometimes the system allows you to select a local file in this menu, if a certain theme is active. If there is no direct replacement, the the theme serves as a “bridge” that allows you to access system sounds.

⚠️ Note: Some topics may contain advertisements or require subscriptions. Read the terms carefully before downloading and select themes marked "Free" (Free).

Use of third-party applications for customization

If the built-in tools seem too complex or limited, Google Play apps come to the rescue. There are a number of utilities designed specifically for Xiaomi and Redmi owners that automate the process of replacing system sounds. These apps often have a friendlier interface than standard tools.

One of the most popular solutions is the application. MIUI Sounds or analogues with names like Custom Charge Sound, and the way they work is to create a temporal theme on the fly. mp3-And this is a file from its gallery, and the app packages it in the theme format and it applies the configuration.

When using third-party software, it is important to pay attention to the permissions requested. The program will require access to storage (to read your audio file) and access to the theme system (to apply changes). Once the sound is installed, the application can often be removed, but the theme will remain active.

• 📲 Utility: Apps allow you to quickly change sounds without deep immersion in the system settings.
• 🔒 Security: Only download programs from a trusted Google Play store, avoiding APK-files from questionable sites.
• ⚙️ Compatibility: Not all apps work equally well on newer versions of HyperOS, check the date of the last program update.

Advanced adjustment and problem solving

Sometimes, after you set a new tune, users find that the sound is not playing, the standard one is playing, or the phone is just vibrating, this may be due to power saving settings or a conflict of profiles, first of all, check if you have a "No Sound" or "Do Not Disturb" mode that can block system sounds.

Also, make sure that the volume of system sounds is not reduced to a minimum. On many Xiaomi smartphones, the volume of media and the volume of system events are adjusted separately. Press the volume buttons and press three dots (or gear) to deploy the full mixer and check the level of the Sistema or Notifications slider.

If you upgraded to HyperOS, the menu structure may have changed. The path to settings often looks like Settings → Sound and Vibration → Additional → System Sounds. In some firmware regions, these items may be hidden, which requires changing the region in the phone settings (for example, India or Indonesia), where the functionality is more widely disclosed.

The following table shows the problems and ways to solve them:

The stability of sound modifications depends on the firmware version and region, so the method with the theme is the most universal solution.
