How to change the battery icon on Xiaomi: styles and modifications

Owners of Xiaomi, Redmi and POCO smartphones often strive to maximize the personalization of the MIUI or HyperOS interface. The standard charge indicator, although functional, quickly gets boring and looks boring against the background of bright wallpaper. Many users wonder whether it is possible to replace the usual β€œdrop” or percentages with something more original, such as animated graphics or minimalistic numbers.

Fortunately, the MIUI shell provides a wide range of customization options that go beyond just changing the wallpaper, and it can be changed without getting a super-user license (root) and without the complex reprogramming of the system, using an official tool from developers, available to everyone.

In this guide, we will discuss the safe method of replacing icons through the theme editor, you will learn to create your own styles or download ready-made modifications, changing the appearance of the status bar beyond recognition, which will make the interface of your device truly unique.

The principle of operation of indicators in MIUI and HyperOS

The charge display system in Xiaomi smartphones is built on the use of graphical resources that are part of the active theme of the design. The standard set of icons is limited to the default theme, usually β€œClassic” or β€œDefault”, but the theme mechanism allows you to replace these resources on the fly.

When you install a new theme from GetThemes, it can completely overlap system images, including the battery icon. But often pre-made themes only change the wallpaper and application icons, leaving system elements unchanged, and that's where manual editing comes to the rescue.

⚠️ Note: Modification of system files to theme is possible only through special tools. Attempting to directly replace files in the folders of the system without root rights will lead to errors or a cyclical reboot.

The modification uses MIUI Theme Editor (or simply Theme Editor) to unpack any theme, replace the battery graphics file with your own, and pack the result back into the installation package. It doesn't require deep programming knowledge, but it requires attention to detail.

Tools and training required

Before you start creating a custom icon, you need to prepare a workplace. You will need a Windows computer, because mobile versions of the editors of the theme are often limited in functionality or not available in global versions of stores.

The main tool will be MIUI Theme Editor, which can be found on official developer forums or in GitHub repositories, which is legitimate software designed for the modder community, and in addition to the editor, you'll need PNG graphics with transparent backgrounds.

Done: 0 / 4

It's important to think ahead. Icons should be clear and readable against any background. Often users forget that the status bar can be both light and dark, so it's worth preparing options for both modes if the editor allows them to be separated, or choose a universal contrasting color.

  • πŸ–₯️ Windows PC (7, 10, or 11) to work with theme editor.
  • πŸ“± Smartphone Xiaomi/Redmi/POCO with unlocked bootloader (not always necessary, but desirable for debugging).
  • 🎨 Graphic editor (Photoshop, Paint.NET) for creating PNG file.
  • πŸ“‚ File Archivator for working with theme packages if there is no built-in editor.

Search and Creation of Graphic Resources

The most creative step is to find or draw a new icon. The standard battery in MIUI is a set of multiple images for different percentages of charge (100%, 75%, 50%, 25%, 10%). To make the shift work, you need to find or draw a similar set.

Graphics files should be in PNG format with alpha-channel support (transparency).The image size is usually small, about 20-40 pixels in height, but for modern high-resolution screens, it is better to look for larger resources (HD/2K/3K) so that they do not blur.

Where can I get the finished icons?
Many ready-made kits (icons packs) can be found on the 4PDA forum in the MIUI branch, on XDA Developers or in the Telegram channels dedicated to Xiaomi modding.

If you create the image yourself, make sure the proportions match the original. Too wide or narrow icon can "go" in the status bar, overlapping the time or network icons.

Use the Export for Web feature in graphics editors to reduce the weight of PNG files without losing quality, which will speed up the theme and save RAM.

Replacement process through Theme Editor

After you've prepared the resources, you can move to the technical part. Run MIUI Theme Editor on your computer. If you already have a favorite theme that you want to refine a little bit, open its file (usually the.mtz extension) through the File β†’ Open menu.

In the theme structure, find the folder that handles the status bar images. MIUI, But most often it's an image directory or a statusbar. stat_battery_empty.png, stat_battery_full.png Or just battery.png.

Replace the standard files with your pre-made images. Make sure the file names match one to one, including the letter register. After the replacement, save the project. The editor will suggest that you reassemble the topic β€” confirm this action.

The main principle of modification is to replace the graphical resource inside the theme container without violating the file structure and name.

The resulting theme file (.mtz) is to be transferred to your smartphone. Connect the device via USB, select the file transfer mode and copy the theme to the MIUI/theme folder or simply to the root of internal memory. Then go to the Themes app, go to the profile and apply the new file.

Compatibility table and file formats

Not all shell versions work with the same resources, and here is a table that helps you navigate file types for different MIUI versions.

MIUI versionFormat of the topicBattery locationSupport for PNG
MIUI 10-12.mtzimages/statusbarComplete.
MIUI 13-14.mtzimages/statusbar_iconComplete.
HyperOS 1.0.mtzstatusbar/batteryLimited.
Global ROM.mtz /.mthemeDepends on the region.Complete.

Note that new versions of HyperOS may make the theme structure more difficult to protect against modifications, and in some cases, the editor may not open the theme correctly, so it makes sense to download the basic theme for your model and modify it, rather than the existing one.

Alternative methods and widgets

If editing system files seems too complicated or risky, there is an easier way to visually change them, which is to use widgets, which don't change the status bar icon itself, but overlap or sit next to it, creating the illusion of a new design.

There's a Widgets section in the GetThemes store, and you can find hundreds of battery displays, from retro indicators to futuristic scales, and you can put a widget on your desktop, and it's the centerpiece of the interface, and it's going to take your attention away from the standard icon.

There are also aggregator apps like KWGT Kustom Widget Maker, which is a powerful tool that allows you to create a battery widget of any shape and color from scratch, so you can draw your graphics and tie the system charge parameter to it.

  • πŸ“² Widgets from the theme store – fast, safe, but takes up space on the screen.
  • 🎨 KWGT Kustom – complete freedom of creativity, takes time to set up.
  • βš™οΈ Modification.mtz – changes the system icon, requires PC and caution.

⚠️ Note: Third-party applications for changing system icons (not through themes) that require access rights ADB Or, Root, can cause system instability, and use it only if you understand the risks.

Solution (Frequent problems)

During the replacement process, users may find that after applying the theme, the battery icon is gone or has become a black square, which means that the file name does not match the expected system or the image format is not supported (for example, JPG substitutes PNG).

Another problem is the percentages are out of sync, and you've replaced the icon, but the percentages of charge are displayed on top of it incorrectly or side-shifted, so you open the topic in the editor and find the description.xml or similar configuration file that spells out the coordinates of the items and adjust them.

If the theme doesn't apply and writes "Installation Error," check the region of the device. Themes created for the Chinese version of MIUI may not work on global firmware and vice versa. In the phone settings, change region to "India" or "China" (temporarily) to allow installation.

What to do if the phone goes into a bootloop?
If after installing the modified theme, the phone stopped booting, boot into Safe Mode (usually by pressing the volume button when turned on) or via Recovery (Wipe Data) to remove the problematic theme.

Don't be afraid to experiment, but always have an original kickback theme at hand.Personalization is the path to creating a device that reflects your character, and replacing the battery icon is just the first step in that direction.

Is it safe to change theme files through the editor?
Yes, it is safe if you are using the official MIUI Theme Editor and don't edit system files directly in the phone's memory. you only change resources inside the theme container, which can be easily deleted.
Do I need Root rights to change my badge?
No, to replace the battery icon by creating or modifying the theme (.mtz) superuser rights are not required.
Why did the interest disappear after the icon was replaced?
You may have used an image that completely covers the text area, or in the theme configuration file, you may have a mapped coordinate. Try using PNG with transparency only around the battery circuit, leaving the center blank.
Can I make an animated battery?
Yes, but it's more complicated. You'll need to create a frame set (sprit list) or use video formats if the MIUI version supports dynamic themes, and most animations are done through complex widgets rather than a system icon.
Where to find the source code of the stock theme?
Officially, the source code is not distributed, but there are lots of stock themes (Stock Theme Extract) on the Internet. Download this theme, open it in the editor, and use its files as a base for your experiments.
