Modern Xiaomi smartphones have powerful batteries, but often the standard settings of the connection to the power supply seem boring or invisible to users. When you connect the device to the network, the system issues a standard notification that is easy to miss in a noisy room. Changing the charging settings allows not only to personalize the gadget, but also to make the process of replenishment more informative and safe.
Owners of MIUI-based devices and the new HyperOS often wonder if you can replace the standard sound of "trills" with a tune from a favorite song or make the screen brighter when you connect the cable. The answer lies not only in the standard settings menu, but also in hidden engineering codes and third-party utilities that extend the functionality of the shell. Understanding these mechanisms will help you fully control the behavior of your smartphone.
In this article, we will discuss all available customization methods: from simple audio file replacement to deep customization. LED-You will learn how to make the phone respond to the cable connection in a unique way, and what to do if standard methods do not work. This guide will be a comprehensive answer to the question of how to make the charging process on Xiaomi as convenient as possible.
Standard sound settings and notifications when connected
The first thing that comes to mind when you want to change your phone's response to the network connection is the standard settings menu. However, the pure "Charging Sound" option is often not available in Xiaomi's global firmware versions. The system relies on the system sounds of the interface. To try to change the standard sound, you need to go to Settings → Sound and Vibration → Additional audio settings. Here you can find items responsible for system sounds, although a direct replacement for "charging sound" may not be depending on the Android version.
If you don't get a change in standard tools, you should pay attention to the design theme, Themes Themes allows you to change the system sounds entirely, and if you download a theme with a unique sound design, you automatically change the network connection sound if the theme author has provided for such a modification, which is the safest way to do so without having to root or install complex software.
For more advanced users, there is the option of manually replacing system files, but this requires caution. Sound files are usually located in the /system/media/audio/ui/ directory. Replacing the Charging.ogg file (the name may vary) with your file with the same name and format can give the desired result. However, without superuser rights (root) this is impossible, and inept actions can lead to a cyclical reboot.
⚠️ Warning: Before any replacement of system files, make sure to make a full backup of the data. An error when editing the system partition can lead to the inoperability of the smartphone.
💡
Use dealer apps to (preview) theme sounds before installing it, so as not to download extra megabytes for the sake of one sound.
Using applications to automate tasks
The most flexible and safe way to change the smartphone’s response to the charger is to use automated applications, the leader in this field is the MacroDroid or Tasker application, which allows you to create scenarios: “If event A (charging connection) occurs, then perform action B (play sound, say text, flash the screen)”.
The process of setting up in MacroDroid is as follows: you add a Power Connected trigger, then select Play Sound, and you select any one. mp3-It's a file from your phone's memory, and it allows you to set up a voice message, a favorite song, a sound effect from a game, and it runs on top of the system, and it doesn't require deep interference with the firmware files.
In addition to playing audio, automation allows you to perform other useful actions, for example, when connected to the network, the phone can automatically turn on Do Not Disturb mode, increase the brightness of the screen or launch an application to monitor the battery, which turns ordinary charging into a smart action that optimizes the use of the gadget.
- 🎵 MacroDroid: Perfect for beginners, has a clear interface and a lot of ready-made macros in the community.
- ⚡ Tasker: The most powerful tool for professionals, allows you to program the most complex logical chains of action.
- 🔋 Battery Charge Notification: A specialty app that not only changes the sound, but also voice reports the percentage of charge.
The secret of long-term work of automatizers
setting up the visual indication and LED-notice
The visual component of the charging process on Xiaomi is also customizable, although the capabilities here depend on the specific device model. On many modern smartphones, the physical LED indicator is replaced by the Always-On Display (AOD) screen. If your device has an LED (usually next to the front camera or in the speaker), its behavior can be controlled.
To adjust the indicator, go to Settings → Screen and Brightness → Notification Indicator (the path may differ). Here you can turn on blinking when charging. The color of the glow is usually fixed hardware (green or orange), but the blinking frequency can sometimes be adjusted through third-party applications such as NotifyBuddy or LED Blinker Notifications. These applications use a flash camera or screen to simulate the operation of the LED if the physical one is not present.
Special attention should be paid to the lock screen. In the shell of MIUI there is a function "Effect on charging." Go to Settings → The screen is always on and the lock screen → The effect when charging. Here you can choose the animation that will be played when you connect the cable. This can be a numerical display of percent, flying particles or the brand logo.
| Model/Series | Type of indicator | Possibility of colour change | Support for AOD |
|---|---|---|---|
| Xiaomi Redmi Note (budget) | Virtual (screen) | No (software only) | Partially. |
| Xiaomi Mi / Mi Mix | Hidden LED | No (hardware) | Yes. |
| Xiaomi 13 / 14 Pro | Screen + LED (in camera) | Yes (programmatically) | Complete. |
| Poco F/X Series | Virtual | No. | Yes (with limitations) |
💡
The visual effects of charging consume extra power. If you charge your phone at night, it's best to turn off the screen animations so you don't waste power.
Engineering menus and hidden codes for diagnostics
For users who want to dig deeper than standard settings, there is the Xiaomi Engineering Menu, which is a hidden part of the system designed to test hardware components, accessed through a set of special code in the Phone app. Enter the code ##6484## or ##4636##. The second code opens the testing menu where you can see detailed information about the battery.
In the 4636 (Testing) menu, select Battery Information. This shows the actual battery temperature, voltage level, health status, and cause of discharge. While you can't directly change the charging sound from here, this menu is critical for diagnosis. If the phone is acting strangely when charging (heating, slowly gaining charge), this is where you'll find the answer to whether the problem is software or hardware.
Some versions of the shells allow you to calibrate the approach sensor or screen through the engineering menu, which indirectly affects the operation of the screen during charging (for example, prevents false switching of the screen in your pocket).
⚠️ Warning: Never change the values in the engineering menu unless you know exactly what a particular parameter is responsible for.
Optimizing fast charging and maintaining the health of the battery
Not only can you change charging visually or soundly, but you can also optimize the energy input. Quick Charge and Power Delivery, which are used in Xiaomi smartphones, allow you to quickly fill the battery, but generate a lot of heat. In the battery settings (Settings → Battery → Battery Protection), you can turn on the option of optimized charging.
This feature is trained in your habits. If you normally charge your phone overnight, the system will bring the charge to 80% and pause the process to complete it just before you wake up. This greatly reduces the degradation of the lithium polymer battery. It's also worth paying attention to the cables: using certified cables labeled 5A or 6A (for 120W charges) is critical.
Cheap cables may not support fast charging protocols, which will cause the phone to charge slowly, and you won't see the "Mi Turbo Charge" or "HyperCharge" logo on the battery menu. Replacing the cable with a quality one is also a kind of charging change that changes the experience.
- 🌡️ Temperature control: Remove the case during fast charging to avoid overheating above 40 degrees.
- 🔌 Original Adapter: Use only native power supplies to activate maximum speeds (67W, 90W, 120W).
- 🔋 Flight mode: To accelerate charging in emergency cases, turn on the air mode, disabling the search network.
Problem Solving: Why the sound or indication doesn't change
Often users are faced with a situation where all settings are applied, but the phone is silently charged. The first reason is a conflict of topics. If a third-party theme is installed, it can block system sounds. Try temporarily switching to a standard theme Classic or Default in the Themes app and check the work.
The second reason is Do Not Disturb or No Sound. In some MIUI builds, the system charging sounds are muted if silent mode is on. Check the sound profile. The third reason is a bug in the operating system itself. After major Android updates, the sound settings may be reset or conflict.
If nothing works, you can try clearing the cache of the Themes and System UI application. Go to Settings → Applications → All applications, find the system processes you want, and click Clear Cache (not data, specifically cache). This is a secure procedure that often solves problems with graphics and interface sound.
