Xiaomi smartphone owners often want to personalize their device’s interface to make it look unique and reflect their individual style. One of the most visible elements of the MIUI system, which catches the eye every day, is the battery charge indicator. The default default icon provided by developers can seem boring or just familiar, which encourages users to look for ways to replace it. On the Redmi 9 model, which runs on Android with the shell of MIUI, the process of changing the appearance of the system elements has its own peculiarities and nuances.
There are several proven methods to transform the visual display of energy levels, from simple settings on the menu to using third-party software. Some methods require minimal effort and take a couple of minutes, while others involve deeper interference with the file system of the device. It is important to understand that customization of the interface is not only about aesthetics, but also about the correct management of system resources. Incorrectly selected themes or fonts can sometimes affect the stability of work, so the choice of tools for modification should be approached responsibly.
In this guide, we will take a look at all the options available to change the battery icon, evaluate their safety and effectiveness. You will learn how to use the built-in shell capabilities, what applications from the official store can help with the task, and also touch on advanced methods for power users. Changing system files without a backup always carries the risk of data loss or interface disruption. Let's look at what tools are at your disposal right now.
Standard display settings in MIUI
Before you resort to installing third-party apps or themes, you need to learn the basic features that the operating system itself provides. The MIUI shell on the Redmi 9 smartphone allows the user to choose from several standard display styles of the charge indicator. This is the most secure method that is guaranteed to not lead to errors in the device or the appearance of bugs.
Go to Settings → Battery → Battery Indicator. Here you will see a list of available options, which can vary depending on the firmware version. Usually the system offers a choice between displaying the percentage of charge inside the icon, next to it or completely hiding the digital value. Also, the option to change the color of the icon depending on the energy saving mode can be available, for example, it can turn yellow or green when energy saving is activated.
While the standard menu is limited, it ensures that all system processes work smoothly, if you just need to see percentages or change color, you don't need to have a deep intervention, but if the goal is to replace the icon form with a non-standard one, you'll have to use other methods.
- 📱 Standard menu allows you to switch modes of displaying percent.
- 🎨 The color of the indicator can change automatically in saving mode.
- 🔒 This is the only method that does not require additional software installation.
Using the Themes app to change style
The most popular and effective way to dramatically change the look of the battery icon on Xiaomi Redmi 9 is to use the built-in Themes app. The Mi Store theme store contains thousands of free and paid designs that replace not only app icons, but also system elements, including status bar indicators. When choosing a theme, it is important to pay attention to the description and screenshots to make sure that the battery design is right for you.
The installation process is quite simple: open the Themes app, search for keywords such as "Battery", "Charge" or "Minimal." Once you download your favorite theme, the system will suggest applying it completely or selectively. In the theme preview menu, find the section responsible for the system icons or status bar.
It is worth noting that some themes may not be fully compatible with your version of MIUI, which may lead to incorrect display of some elements, in which case it is recommended to either choose a different theme or use the component mixing function. You can take your favorite battery design from one theme, and leave the rest of the interface elements standard or take from another source.
- 🔍 Theme search is carried out by keywords in the Mi Store.
- ⚙️ The application of the theme can be complete or selective (Icons only).
- 🔄 Ability to combine elements of different themes for unique design.
💡
Before applying a new theme, be sure to take a screenshot of your current desktop and icons so you can quickly return to your familiar look if you don’t like the new design.
Customization through font installation
Many users are unaware that installing third-party fonts on Xiaomi often entails changing system icons, including the battery icon. Font designers often include graphic elements in the file package that replace standard Android images. This is because the font on the system is not only letters, but also a set of characters used by the interface to render various elements.
To do this, you have to go to the screen settings and select the Font. You can find a lot of options in the font store that you open that change the style of numbers and system icons when you install them. Once you load and use the font, the system automatically restarts the interface and you see changes. If the battery icon changes with the font, then the font author has provided this opportunity.
However, be careful: some fonts may not be optimized well for Redmi 9 screen resolution, which will lead to fuzzy image or shifting interface elements. If after installing the font you notice problems with text readability in other applications, it is better to return the standard font. This method is good in that it changes the entire visual style of the device, creating a harmonious image.
What to do if the font caused failures?
Advanced Methods: MTZ Theme Editor
For users who want complete control of the design and don't find the right solution in the standard store, there is a tool called MTZ Editor or similar theme editors. This method requires connecting a smartphone to a computer or using file managers with advanced rights. The essence of the method is to manually replace the graphic file responsible for rendering the battery inside the theme archive.
You will need to find the theme file with the.mtz extension, unpack it and locate the file. status_bar_battery.png or similar, depending on the version MIUI. By replacing this file with your own image (size and format), you can reassemble the theme and install it on the device, which gives you absolute freedom of creativity, but requires carefulness and compliance with the technical parameters of the images.
It is important to understand that incorrect replacement of system files can cause the charge indicator to disappear completely or be displayed incorrectly (for example, with a white square). Before starting manipulations, it is strongly recommended to create a full backup of data. Also make sure that the battery image has a transparent background (PNG format), otherwise it will look like an inserted spot on the interface.

Possible problems and solutions
During customization, users of Xiaomi Redmi 9 may face a number of typical problems, such as when a new theme is installed, the battery icon may become invisible on a light or dark background, which often happens if the theme writer has not provided an alternative rendering option for different display modes, the solution may be to change the wallpaper to contrast or return to a standard theme.
Another common problem is the increased charge consumption after installing heavy themes with live battery animation. Although the icon itself is static, some themes add charging effects that strain the processor. If you notice that the phone has become discharged faster after changing the design, try turning off the live wallpaper or pick a lighter theme.
It is also possible to create image artifacts if the resolution of the graphics in the theme does not coincide with the pixel density of the screen of your device, in such cases, it helps to reset the theme settings to factory values.
- 👻 The indicator has become invisible: change the theme or wallpaper to contrasting.
- 🔋 Fast discharge: abandon those with live animations and widgets.
- 🖼️ Artifacts on the screen: check the resolution of the theme of the phone model.
⚠️ Warning: If after installing the theme, the phone stopped responding to touches or got stuck on the screensaver, try booting into Safe Mode by holding the off button at start, and remove the problematic theme app.
💡
The safest and most effective way to change the battery icon is to use official themes from the Mi Store, as they are tested for compatibility with MIUI.
