Xiaomi smartphones are famous for their functionality, but users often face limitations in customizing the interface. Owner Redmi 9 Pro may notice that the standard animation of the connection to the power supply remains unchanged, despite the presence of third-party themes. Changing the visual charging style is not just a matter of aesthetics, but also a way to personalize the device to your taste, making it recognizable.
In this article, we will take a closer look at all the available methods of changing the screensaver and animation when connecting the cable. We will look at both the built-in capabilities of the MIUI shell and third-party solutions that require a deeper dive into the system settings. You will learn which tools are safe and which can lead to unstable operation of the gadget.
Before experimenting, it’s important to understand the architecture of the GUI in Android. Standard tools don’t always allow you to replace the system animation on the fly without installing additional applications or themes. However, there are proven ways to get around these limitations and achieve the desired result.
Standard settings Always On Display and locks
The first step to personalization is learning what’s already built into your Redmi 9 Pro. The MIUI shell offers a feature called “Always On Display,” which can display time, date and notifications even when the phone is in sleep or on charge.
To activate this function, you need to go to the settings menu. Navigating the system requires care, since points can be hidden in the submenu. Go to Settings, then select the Lock Screen section. Here you will find Always On Display and the screen lock.
Inside this menu, you have a style store where you can download new designs, some of which change the look of the screen during downtime, and if the phone is connected to the network, these settings often continue to work, creating the effect of a modified screensaver.
- 🔋 Enable Always On Display to display information in standby mode.
- 🎨 Use the built-in theme store to download new lock styles.
- ⏱️ Set up a screen schedule so that it only lights up at night or during the day.
- 📱 Make sure that the screen does not burn out pixels during prolonged display of a static picture.
⚠️ Continuously working on Always on Display AMOLED-screens (if supported by your modification) or even on the screen IPS-Redmi 9 Pro matrices can lead to accelerated battery discharge and potential burnout of static image elements.
Using Thematics through the “Themes” App
The most effective and safest way to change the visual design of the system, including elements related to charging, is to use the official Themes app. Xiaomi developers allow themes authors to implement their own graphic elements that replace standard icons, fonts and, importantly for us, system animations.
The process of finding the right topic can take time. In the search bar of the Topics app, it is recommended to enter keywords such as "charging", "animation" or "battery." downloaded themes apply completely, but some of them allow you to select only certain components, for example, only wallpaper or only lock style.
Once the theme is installed, the system may need to reboot to correctly display all elements. If the charging animation hasn’t changed after applying the theme, it may not support modifying that particular system process on your version of MIUI.
☑️ Checking before setting the topic
It is important to note that not all themes work equally well.Some may cause interface lags or conflict with other personalization settings.Always read comments from other users before installing to avoid device performance issues.
Installation of your own images through third-party applications
If the built-in tools don't meet your needs, Google Play Store apps come to the rescue. There are many programs that layer on top of the system interface and simulate the charging process with user graphics.
One popular solution is to use launcher applications or special charging utilities, and once you install the software, when you plug in the cable, the image or video you choose will automatically open on the screen, creating the effect of completely replacing the system screensaver.
But it has its own peculiarities: an application must have permission to run over other windows and access to the battery status, without these permissions, functionality will be limited, and such programs can consume additional CPU life.
| Annex | Type of content | Impact on the battery | Difficulty setting up |
|---|---|---|---|
| Battery Charge Animation | Video/Gifts | Average. | Low. |
| Charging Battery Screen | Images | Low. | Low. |
| Custom Charging Screen | Video 4K | High. | Medium |
| Amoled Backgrounds | Statics | Minimum | Low. |
Security of Third Party Applications
Advanced customization through the engineering menu
For power users who aren't afraid to experiment, there's access to hidden system settings. The Redmi 9 Pro's engineering menu allows you to test various components, including the display. While there's no direct replacement of the charging animation file, you can calibrate the proximity and color sensor, which indirectly affects how you perceive the picture when you charge.
The engineering menu is logged in via a special code set in the Phone app. Enter the combination ##6484##. The CIT menu will open. You can check the screen performance here, but be careful: changing unknown parameters can reset the touchscreen.
Some users try to find system animation files in the root directory of the system. This requires superuser rights (Root). Animation files are usually located in the directory /system/media/ or /system/product/media/. Replacing system files is a risky operation.
⚠️ Note: Making changes to system files without having a backup and understanding the structure of Android can lead to a “bootloop” (cyclical reboot) of your Redmi 9 Pro.
💡
Before any manipulation of system files, make sure to make a full backup of the system partition via Recovery (TWRP) or create a restore point.This is the only way to guarantee that the phone will be brought back to life in case of an error.
The solution: why the screensaver does not change
Often users are faced with a situation where seemingly all settings are applied, but when connecting the charging, a standard lightning appears. This may be due to the caching of graphic elements by the system. MIUI aggressively manages memory and can block the work of third-party applications that replace the charging screen.
You need to check the power saving settings for the application that should display your screensaver. Go to Settings → Applications → All applications, find the desired program and select Activity Control. Set the value No restrictions. This will allow the application to run in the background and activate when a power connection event occurs.
The problem may also be a conflict of topics: If you have a theme from the store and an app installed to change the screensaver, priority may be given to the system theme. Try to return the standard theme "Classic" and check the third-party software.
- 🚫 Check if Do Not Disturb mode is enabled or energy saving is turned on, blocking animations.
- 🔄 Clear the cache of the “Themes” and “System” application UI» through the storage settings.
- 📲 Make sure the charging cable is in good working order and transmits data, not just current (for some features).
- 🔒 Remove the screen lock and check if the lock widget does not block the charging animation.
Optimization and Impact on Productivity
The use of complex animations and video screensavers while charging certainly loads the Redmi 9 Pro processor and graphics accelerator. Although the device is charged from the grid, the additional load can lead to heating of the case.
If you notice that the phone has become more hot than usual while charging with a new screensaver, it is better to abandon the use of video animations in favor of static images.
In addition, the constant operation of a bright screen with high detail can reduce the life of the matrix. It is recommended to use screensavers with a predominance of black, especially if you have a model with a high-resolution screen. AMOLED-A screen where the black pixels are simply turned off and do not consume energy.
💡
The optimal balance between beauty and performance is to use static, high-resolution dark wallpaper instead of heavy video animations.
