Modern smartphones like the Xiaomi Redmi 9 offer users the most personalized interface. One of the most effective ways to set your device apart from hundreds of others is to install dynamic background images. Live wallpaper is not just a static picture, but full-fledged animation that responds to touch or time of day, making it more enjoyable to use the gadget.
Budget and mid-budget owners often wonder how much this animation will affect performance. The Redmi 9, which runs the MIUI shell, has a smart optimization that allows even complex visual effects to be used without a critical drop in speed. However, to keep the system running consistently, it is important to understand the differences between embedded tools and third-party solutions.
In this article, we will take a look at all the available methods for activating animated backgrounds. You will learn how to use the built-in store with the ones where to look for quality free options and how to properly configure the system so that the battery does not run out too quickly. This guide will help you make the lock screen and desktop truly unique.
Built-in MIUI features for Redmi 9
The MIUI shell installed on the Redmi 9 out of the box already contains powerful tools to change the appearance. You do not need to download third-party software immediately, since the basic functionality is often sufficient for most users.
The first way is to access a global directory, go to Settings → Wallpaper or find the app of the same name in the Tools folder, and there's a huge selection of both static and animated images that are officially optimized for your device. The official live wallpaper in the MIUI directory does not cause conflicts with the system and is guaranteed to work stably.
It's worth noting that some live wallpapers can be marked as paid or require you to view ads to activate. This is normal practice for free firmware versions. If you choose the ad option, just wait for the video to end and the background will be automatically applied to the lock screen or home screen.
⚠️ WARNING: When downloading live wallpaper through the built-in store, make sure you have Wi-Fi enabled. Animation files can weigh between 10 and 50 MB, which when using mobile traffic can quickly exhaust your data plan.
- 🎨 A huge selection of official topics, divided into categories.
- ⚡ Optimized energy consumption for built-in animations.
- 🔄 Automatic update of the wallpaper collection "Carousel" (if included).
- 📱 Ability to preview animation before installation.
Using the Google Live Wallpaper app
Since Xiaomi Redmi 9 is Google certified and runs on Android, the search giant’s Live Wallpaper system is often installed on board. Even if the icon is hidden in the back of the menu, the functionality is available through standard personalization settings. This is one of the most reliable ways to get quality animations without the risk of virus infection.
To activate this method, go to Settings → Wallpaper → More Wallpaper (or “More Wallpaper”). In the list that opens, select “Live Wallpaper.” Here you will find classic Android animations like floating bubbles, spinning planets or changing colors. These effects are deeply integrated into the core of the system, so they consume minimal CPU resources.
If you don't have a standard set, you can expand the functionality through the Google Play Store. Find the Wallpaper Engine and install it. Once installed, new categories will appear in the same selection menu. Google's system live wallpaper often has speed or color settings, allowing you to fine-tune your visual style.
💡
To save battery power in the settings of live wallpaper from Google, you can often turn off the display of animation on the home screen, leaving it only on the lock screen.
It's important to understand the difference between live wallpaper and wallpaper carousel. Carousel is a feature that changes static images at intervals, whereas live wallpaper is continuous animation. In MIUI, these functions may overlap, but technically they are implemented differently.
Installation of video from the gallery as wallpaper
Often users want to put as a background a specific video downloaded from social networks or shot yourself. standard Xiaomi tools can not do this, as the system supports only image formats and special theme packages.
One of the most popular and proven solutions is the Video Live Wallpaper app, or its analogues, available on Google Play, which is simple: the program takes the selected video file (mp4, webm) and creates a virtual file of live wallpaper from it, which the system perceives as a standard background.
After installing the application, follow the following steps:
1. Open the app and select the video from the gallery.
2. Configure the settings: sound (usually it is better to turn it off), zoom and playback cycle.
3. Press the installation button and confirm the selection in the Android system window.
☑️ Checking before installing video wallpaper

Optimization and Impact on the Battery
The main fear of users when installing a live screensaver is a fast battery drain. Xiaomi Redmi 9 is equipped with a battery capacity of 5020 mAh, which is a great indicator, but the animated background is still an additional consumer of energy. The screen and the processor are forced to constantly process graphics frames, even when you are not using the phone actively.
To minimize the impact on autonomy, follow simple rules. First, avoid using bright, white animations on your own. AMOLED-Screens (although Redmi 9 is a good one) IPS, The brightness principle is relevant, because the backlight will work at maximum. Secondly, use the Dark Theme function in combination with dark live wallpaper - this reduces the overall power consumption of the display.
Also, MIUI has built-in protection mechanisms, so if the battery power drops below 15-20%, the system can automatically turn off the live wallpaper and replace it with a static black or standard image, which is a standard behavior designed to extend the life of the device in a critical situation.
💡
Live wallpaper consumes about 3-5% more battery life per day than static images, provided optimized animations are used.

Addressing common problems
In the process of setting up users of Redmi 9
If the animation is reset, check if the wallpaper provider app is worth the "Clean When Close" list, and make sure that the theme settings don't check "Apply only to the lock screen." Sometimes it helps to completely reinstall the live wallpaper app and reissue all the permissions you requested.
Another problem is desynchronization of sound or lack of response to touch, which can occur if the video file is damaged or has a non-standard codec, in which case try converting the video to H.264 MP4 before installing, and the conversion eliminates encoding errors that can cause rendering failures.
⚠️ Warning: Do not install multiple live wallpaper apps with auto-start function at the same time.This will create a resource conflict, and none of the applications will work correctly, which will lead to a drop in the interface.
- 🔄 Reset the theme settings to standard if the interface starts to glittle.
