How to change the battery indicator Xiaomi MIUI 12

Xiaomi smartphone owners running the MIUI 12 shell often face the desire to personalize the device interface. One of the most noticeable elements of the system is the battery charge indicator, which by default has a standard look. Changing its appearance allows not only to stand out from other users, but also to make interaction with the gadget more aesthetic and comfortable.

Unlike many other manufacturers, the Chinese giant offers a wide range of customization options without having to obtain root access rights. However, the process of replacing an icon can seem confusing for a beginner due to the extensive menu of settings and features of the theme engine. In this article, we will discuss all the available methods, from simple built-in solutions to advanced manipulation of system files.

It is worth noting that the MIUI interface is constantly updated, and the location of some items may vary slightly depending on the firmware version (Global, China, EEA).However, the basic principles of replacing graphic elements remain unchanged.

Standard Replacement Methods through the Topics App

The easiest and safest way to change the look of a battery icon is to use the official Theme app, a built-in tool that is pre-installed on all Xiaomi devices, where users can find thousands of pre-built designs created by both the company and independent designers. It's important to understand that in most cases, it's not a single icon that changes, but the entire visual style of the system.

To get started, you need to open the app and go to the search section. In the input bar, you should type in keywords such as "battery icon", "status bar" or "minimal icons". After that, the system will offer a list of relevant topics. Attention: when downloading themes from third-party sources or regions (for example, India or Indonesia), the functionality can be expanded, but you will need to change the region in the phone settings.

When you choose your favorite option, click Download and then Apply. The system will prompt you to select components for installation. Here, it is critical not to click "Apply All", but to select the option "Configure Theme". In the menu that opens, you can only leave a tick opposite to "Icons" or "Battery Style", if such item is highlighted separately by the the theme developer, this will save your wallpaper and fonts, changing only the necessary elements.

• 🔋 Open the Themes app on the main screen.
• 🔍 Type "battery style" or "battery icon" into search".
• ⚙️ Click Set theme before use to select only the right items.
• ✅ Confirm the change, the system will automatically restart the interface.

Sometimes, after applying a new theme, the battery icon may not change immediately, which requires a complete reboot of the device. Also, it is worth considering that some themes only change the style of displaying the percentages, but not the shape of the battery itself. Always carefully study the screenshots in the description of the topic before downloading.

⚠️ Note: When installing themes from unknown sources, make sure the developer is highly ranked.Poor themes can cause interface lags or incorrect charge display.

Use of third-party launchers for customization

If the built-in MIUI 12 feels limited, third-party launchers come to the rescue, replacing the desktop and notification bar completely, giving you access to hundreds of plugins. The most popular solution in the Android ecosystem is Nova Launcher in conjunction with plugins, or specialized control panels.

However, there is a technical limitation to remember: standard launchers change application icons, but rarely touch the status bar where the battery indicator is located. Deep modification of this particular element will require more sophisticated tools, such as Substratum (requires root) or specialized modules. Without superuser rights, launchers are limited in this aspect.

However, there are launchers with built-in status bar customization features, such as Microsoft Launcher or Smart Launcher. They allow you to change the color and style of some system indicators through their settings. To activate such functions, you usually need to go to Launcher Settings → Appearance → Status Bar.

Using third-party software carries risks, primarily increased RAM consumption, which can be critical for Xiaomi’s budget models, and some launchers may conflict with MIUI navigation gestures, causing inconvenience when controlling one finger.

Configure the display of percentages and styles in MIUI 12

In MIUI 12, developers have focused on visualizing the charge, and in addition to changing the graphical shell, the user can change the way the numerical values are displayed, this is done through a standard settings menu, which ensures the stability of the system, and you do not need to download additional files to access these parameters.

Go to Settings, then select Notifications and Status bar (or just Status String) and there's a "Show Battery" switch on it, and you'll see a few options if you click on it: percentages inside the icon, percentages next to the icon, or just a graphic image, depending on your topic: white digits are better on dark backgrounds, and blacks are better on light backgrounds.

An important aspect is that Dynamic Battery is supported in some themes, and this effect creates an animation of the battery filling by simulating a liquid. To activate this feature, the theme must support the HyperCharge engine or similar Xiaomi visualization technologies.

Remember that too many animations and dynamic elements in the status bar can increase energy consumption slightly, but if you want maximum autonomy, choose static, simple icon styles without complex graphics.

Advanced customization through ADB and system files

For users who want to gain full control over the appearance of their Xiaomi and are not afraid of technical manipulation, there is a method of modifying system resources. battery_stat.xml Or similar resources. But starting with Android. 11 and MIUI 12, Access to these files is limited.

To implement this method, you will need a computer, a USB cable and an installed ADB (Android Debug Bridge) package. First, you need to activate the developer mode on the phone: seven times click on the build number in the About Phone section. Then turn on the USB debugging in the Developer menu.

The process of replacing is this: You plug your smartphone into your PC, open the command line, and type commands to access the file system, and often you need to temporarily grant additional permissions through ADB, because a standard file manager won't let you into the root of the system.

adb shell


pm grant com.android.settings android.permission.WRITE_SECURE_SETTINGS

Once you have the right to replace the system images of the battery with your own, renaming them according to the originals. It is critical to keep the original resolution and format (usually PNG) of the files, otherwise the system will not be able to display them and the indicator will disappear.

⚠️ Note: Any manipulation of system files through ADB An error in the file name or format can cause the charge indicator to disappear or a cyclic reboot.

Solving problems with displaying the battery icon

When experimenting with themes and settings, MIUI 12 users often encounter bugs, the most common being the disappearance of the battery icon or displaying the wrong percentage of charge, which may be due to a theme cache conflict or an error in the code of the installed shell.

The first step in diagnosis should always be to clear the Themes app cache and System UI. To do this, go to Settings → Apps → All apps, find the process you want and click Clear Cache. Don't confuse it with Clear All Data, as this will reset your personalizations.

If the problem persists, try switching the region of the phone. Sometimes theme servers for a particular region (for example, Russia) may have a stripped down directory or bugged versions of popular topics. Switching to the region "India" or "Singapore" often solves the problem of accessing the correct resource files.

It’s also worth checking if power saving mode is on, and in this mode Xiaomi forcibly changes the color of the indicator to yellow and can ignore some visual settings of the theme for the sake of saving CPU resources.

The impact of thematics on system performance

Many users wonder if the complex graphics of the battery indicator affect the speed of the smartphone. In the case of MIUI 12, which is already known for its heaviness, this question is axalen. Dynamic themes using live wallpaper for status bar or complex animation scripts really consume more CPU resources.

If you notice that after the theme change, the phone starts to heat up or discharge faster, the problem may be in the visual elements, especially in high-resolution graphics for screens with a frequency of 90 Hz or 120 Hz. The system is forced to constantly redraw the interface elements.

For owners of budget models such as the Redmi Note series or Poco M, it is recommended to use static themes with a minimalist design.This will not only save battery power, but also make the interface work smoother, eliminating micro-freeze when switching between windows.

• 📉 Dynamic themes can increase battery consumption by up to 5% per day.
• 🚀 Static icons do not affect the performance of the processor.
• 🎨 High-resolution graphics require more RAM.
• ⚡ Animated status bars may conflict with Always-On Display.

💡

Tip: If you want to use a beautiful but heavy theme, turn off the Advanced Optimization mode for background processes in your battery settings, but be prepared for more frequent charging.

In conclusion, the balance between beauty and functionality is a choice for every user. MIUI 12 provides tools for any scenario, whether it be maximum performance or unique design.

💡

The best choice is to use official themes with high ratings that have been tested for compatibility with your version of Android.
