Xiaomi’s Redmi line of smartphones are famous for their flexibility in customization, allowing owners to turn a standard device into a unique gadget. One of the most noticeable elements of personalization is the battery charge indicator, which is located in the status bar at the top of the screen. The standard look of the icon can seem boring or merge with wallpaper, which is especially true for the Redmi 9 model, which runs on the shell of MIUI versions. Changing the appearance of this element not only pleases the eye, but also helps to read the power status of the device more quickly with a glance.
There are several proven ways to change the display style of the percentage and the shape of the battery, ranging from built-in system functions to installing third-party themes. You do not need to be an expert in programming or get root rights to achieve the desired result. In most cases, it is enough to simply activate the desired option in the developer menu or download the design file from the official store. Below we will discuss in detail all available methods, their pros, cons and technical nuances of implementation on a device with a Helio G80 processor.
Use of built-in design themes in the Topic app
The easiest and safest way to change the look of a battery icon is to use the regular Theme app, which is preinstalled on every Xiaomi smartphone. The store has thousands of free and paid designs that completely replace system icons, including status indicators. To get started, open the app and search for queries like “Battery”, “Charge” or “Minimal”.
Once you have selected the right theme, you don't have to use it fully if you like your current wallpaper and fonts. Just click Apply and then select the option to Set up the theme. Here you'll see a list of components: lock screen, wallpaper, system icons and most importantly, status bar icons. Make sure the tick is only on the right elements so as not to disturb the overall style of the MIUI interface.
Why do some things not change the battery?
It is important to understand that using a third-party theme can affect the autonomy of the device, as some graphic elements require more resources to render. However, on Redmi 9 with its optimized system, this effect is minimal. If after installing the theme, the battery icon becomes unreadable or disappears, just return the standard "No Limits" theme through the same menu.
Configure the percentage of charge in the battery menu
Many users confuse changing the shape of the icon with setting the display of the numerical value of charge. In the shell of the MIUI, there is a separate menu that allows you to flexibly manage how exactly the energy information is shown. To get there, go to Settings, then select the Battery item and click on the gear icon in the upper right corner of the screen. Here is the Charge Percentage switch.
When you activate this setting, you'll have three options: "Inside the Battery Icon," "Near the Icon," or "Do Not Show." Choosing the "Inside the Icon" option visually changes the icon itself, making it more informative, as the numbers appear directly in the indicator container. This is especially convenient on the 6.53-inch Redmi 9 screen, where there is enough space at the top of the screen to read the information comfortably.
💡
If you have chosen to display a percentage inside the icon but the numbers are not visible on the light wallpaper, try changing the background to a darker one or use a battery widget with contrasting text color.
It is worth noting that this setting is system-based and does not require additional software installation. It guarantees stable operation without the risk of interface bugs. However, customization options are limited only by the position of the numbers; changing the color or shape of the container itself through the standard Settings → Battery menu will not work.
Activate advanced settings through the developer menu
For more advanced users who want to access hidden features, there is a developer menu. Some versions of MIUI firmware for Redmi 9 provide additional formatting options for the status bar. To activate this mode, you need to quickly click 7 times on the build number in the About Phone section. Once you have the message "You became a developer", a new option will appear in the settings menu.
Inside the developer menu, look for sections related to UI-Although there may not be a direct replacement for the battery icon, interface scaling or pixel density settings are often available (DPI), This visually changes the size of all the elements, including the charge icon. Be careful: changing too complex parameters can lead to incorrect display of text in other applications.
⚠️ Warning: Do not change the values in the developer menu unless you are sure of their purpose. Resetting to factory settings may be necessary to restore stable operation of the system.
This method is recommended only if the standard methods do not meet your visual adjustment needs. For most users, the themes store and standard battery menus are sufficient. Experiments with USB debugging and other engineering functions are best done at your own risk.
Installation of modified system fonts
An unobvious but effective way to change the appearance of the battery icon is to install special fonts. Some custom fonts for Android contain replaced system characters, including the battery icon. You can download such fonts through the Themes app in the Fonts section or from third-party verified sources.
Once the font is installed and the device is rebooted, the system will tighten new graphic elements, making the icon thinner, bolder, or reshaped without heavy themes. However, compatibility of this method depends on the version of MIUI: in new security updates, Xiaomi often blocks the replacement of system icons through fonts.
If the battery icon is missing or appears square after applying the font, return the standard MIUI font immediately. This indicates that the resource part of the font does not fully match your version of the operating system.
Comparison of methods of change of indicator of charge
To make it easier for you to choose the right way, we have systematized the basic methods in a table, each of which has its advantages depending on what is more important to you: stability, appearance or minimalism, analyzing the characteristics will help you avoid unnecessary actions and get the desired result immediately.
| Method | Difficulty | Security | Variability |
|---|---|---|---|
| Annex Topics | Low. | Tall. | Very high. |
| Battery settings | Low. | Tall. | Low. |
| Developer menu | Medium | Medium | Medium |
| Systemic fonts | Medium | Medium | Depends on the typeface. |
As you can see from the table, using the Themes app remains the leader in the combination of security and capabilities. This is the best choice for Redmi 9 if you want to radically change the style of the interface. The method with battery settings is suitable for those who only care about functionality and a clear understanding of the level of charge.
Frequent problems and their solution
Users may encounter various technical difficulties in customization, such as the battery icon becoming transparent or disappearing after installing a theme, often by simply restarting a smartphone or cleaning the theme app cache through the application management menu, and the problem may be a conflict between Android versions and theme resources.
Another common situation is that the battery icon doesn't change color depending on the energy saving mode, which is a regular behavior of the system that is difficult to change without deep code intervention. If you notice that after the changes, the phone starts to drain faster, delete the last topic you installed and check the consumption statistics in the Battery section.
☑️ Diagnostics of Icon Problems
In rare cases, visual bugs can be caused by corrupting system files. If standard recovery methods don't work, it makes sense to reset settings, saving important data beforehand. Remember that the stability of Redmi 9's work is more important than the beauty of the interface.
Optimizing battery life on Redmi 9
Once you have adjusted the look of the indicator, you should think about the energy efficiency. A beautiful icon should not distract from the real state of the battery. In the MIUI settings, there is a function of Optimization of memory and background management, which helps to extend the life of the device.
It is recommended to periodically check the list of applications that use the most energy, turning off background activity for rarely used programs will positively affect autonomy, and do not ignore system updates, as they often contain patches that improve power algorithms.
💡
Competent adjustment of visual elements should not be at the expense of performance and time of operation of the device.
Use Energy Saving mode at night or when you are in a bad grid area, which will help keep you charged, even if you actively use bright and heavy themes during the day. Balance between aesthetics and functionality is the key to comfortable smartphone use.
Additional opportunities for customization of the status bar
Changing the battery icon is just the beginning of the Redmi 9 personalization journey. The status bar allows you to change not only the charge icon, but also the style of the watch, notification icons and signal grid. By combining different themes and fonts, you can achieve a unique look that will distinguish your smartphone from thousands of others.
Remember that too much detail can overload visual perception. Try to be minimalist by choosing themes that do not distract from the main content on the screen. A well-chosen battery style should fit harmoniously into the overall design concept of the desktop.
⚠️ Warning: When installing themes from unverified sources, there is a risk of malware getting into the system. Use only the official Xiaomi store or trusted resources.
Experiment with settings, but always leave the possibility of a quick return to the original state. MIUI system is flexible enough to satisfy the needs of most users, providing tools for both beginners and advanced enthusiasts.
