Installing live wallpaper on Xiaomi MIUI 12: The Complete Guide

Xiaomi’s current MIUI 12 smartphones offer users incredibly flexible personalization capabilities. Lock screen and desktop are no longer static images, becoming dynamic spaces that respond to touch and time of day. Installing live wallpaper is the easiest way to differentiate your device from the mass of identical gadgets and give it a unique character.

However, despite the seeming simplicity, the customization process often raises questions from owners of Xiaomi Redmi and Poco. Standard methods may differ from the usual in Android One, and the built-in theme store sometimes hides really high-quality animations behind paid access. In this article, we will discuss all the nuances of how to make the screen background live and optimize its operation.

It's worth noting that live wallpaper is not just a beautiful picture, but full-fledged code that is constantly executed by the processor. Understanding this fact will help you to correctly approach the choice of content, so as not to turn the flagship into a "brick" with a battery that has died in three hours. We will consider both standard tools and third-party solutions.

Integrated personalization tools MIUI 12

MIUI 12 has received significant visual updates, including a new live wallpaper management system, which, unlike previous versions, divides animations into two categories: lock screen and desktop, allowing complex scenarios where, when unlocked, one picture flows smoothly into another or changes depending on the time of day.

You don't need to download any additional apps to access the basic settings. The system already contains a set of pre-installed animations that are optimized for the hardware of your smartphone. To activate them, just go to the Settings menu. → Wallpaper. Here you'll see the "Block" and "Desktop" tabs, which change the context of the settings.

It is important to distinguish between the themes and wallpapers in the Xiaomi ecosystem. The themes section is a global interface change that includes icons, fonts and system sounds. The wallpaper section works exclusively with background images and animations. To set a standard live background, select your favorite preview and click Apply.

⚠️ Warning: Some built-in live wallpapers may automatically turn off when you turn on Power Savings mode. If the animation is lost after charging the device, check the energy saving settings.

And the special thing that we're looking at is the Super Wallpaper feature that came out of this version of the firmware, which is complex animations of planets or abstract worlds that scale from lock screen to desktop, and they create a depth and three-dimensional space effect, but they require more graphics accelerator resources.

Using the “Themes” application for extended selection

If you don't have a standard set, the main source of content is Themes, an aggregator where millions of authors from around the world publish their work, and to find the actual wallpaper, rather than the full topic, you need to use the search filters in the app correctly.

Open the Themes app and go to the Profile tab, then select Wallpaper. There's a huge catalog. To find animated options, use keywords in the search bar, such as "Live", "Animation" or "Video", the system will offer options that are compatible with your Xiaomi model.

The installation process from the directory is slightly different from the system one. After you choose the option you like, click Download, wait until the download is over, and then click Apply. Note that some authors make their work paid or available only to users with a certain status in the Mi Account community.

• 🔍 Use the “New” or “Trend” tags to find fresh work optimized for the latest updates MIUI.
• ⭐ Pay attention to the rating and number of downloads – popular works are usually better optimized and use less battery.
• 📱 Check compatibility: Some complex wallpapers may not display correctly on low-resolution screens or drop-shaped cutouts.

There is also the option of importing local files, and if you downloaded wallpapers from the Internet in.mp4 or Xiaomi specific format, you can add them through the Import button in the theme app, which opens up thousands of free animations not featured in the official directory.

💡

Before installing a heavy theme or wallpaper from a third-party source, back up important data, as poor-quality code can cause a cyclical launcher reboot.

Installation of video wallpaper through third-party applications

Xiaomi's regular tools make it difficult to set up random video from the gallery as a background. For this purpose, specialized applications from Google Play, such as Video Live Wallpaper or Wallpaper Engine, are best suited. These programs take the rendering of the video file and transmit it to the system as a static but changing background.

Once you install this application, the action algorithm is the same for all models: you select a video file from the phone's memory, adjust the framing and volume settings (if you need sound), and then the application asks for permission to use as wallpaper.

But here's the big nuance of MIUI 12: An aggressive energy-saving system can kill the wallpaper-reproducing process immediately after you turn off the screen or after a few minutes of downtime, and to avoid that, you have to manually configure exceptions for the player application you select.

Go to Settings → Apps → All apps, find your live wallpaper player and go to Battery. Select No Limits mode. Only then will the system allow the application to run in the background constantly, providing smooth animation on the desktop.

⚠️ Attention: Installation of high-resolution video wallpapers (4K) can lead to heating of the smartphone body in the camera area, as video decoding falls on the video core of the processor.

Optimization and Impact on Autonomy

The use of dynamic backgrounds inevitably affects battery life. Unlike static images that are simply stored in memory, live wallpaper requires periodic access to the processor and, in some cases, motion sensors or a gyroscope to create a parallax effect.

The most resource-intensive are the "Super Wallpaper" and scenes from the Wallpaper Engine, where the rendering takes place in real time. If you are critical to autonomy, but want to give up beauty, it is recommended to use short video cycles with dark colors. On AMOLED screens, which are equipped with many flagships Xiaomi, black means off the pixel, which saves energy.

You should also turn off the parallax effect (background movement when tilting your phone) if it is not critical. This can be done from the Settings menu → Wallpaper → Settings of live wallpaper (the path may vary depending on the version).

Another important aspect is RAM: Heavy live wallpaper can be uploaded from memory first if you run a heavy game or navigation app, which will cause you to see a static picture when you return to your desktop until the animation restarts.

• 🔋 Use dark themes and videos with a predominance of black to save charge on the Internet. AMOLED-screen.
• 🚫 Turn off the live wallpaper on the lock screen if the smartphone discharges too quickly in standby mode (pocket).
• ⚙️ Make sure that the developer settings do not include background process limitation, which may conflict with the work of the wallpaper.

The Solution: Why Live Wallpaper Doesn't Work

Users often experience a situation where, after installation, beautiful animations turn into a static image or disappear altogether. The most common reason in MIUI 12 is the work of a memory optimizer, the system considers the running wallpaper process unnecessary and ends it to free up resources.

To solve the problem, you need to fix the application in memory, open the list of running applications (multitasking menu), find the card of your launcher or wallpaper application, pin it with your finger and press the lock icon, which will prevent the system from forcibly completing the process.

The second reason could be a version conflict: If you upgraded from MIUI 11 to MIUI 12 through Recovery, old live wallpaper files may conflict with the new system, in which case cleaning the cache of the Themes app through the Settings menu → Apps → Topics → Memory → Clear the cache helps.

If the live wallpaper is slowing down or causing a "friest" interface, try to lower the quality of the video or choose less complex animations. An overloaded interface is not only unpleasant visually, but also makes using a smartphone impossible. In extreme cases, it is worth returning to static but high-quality images.

💡

The stability of the live wallpaper on MIUI 12 directly depends on the correct settings of energy saving and fixing the process in RAM.
