Smartphone owners in China often face a mysterious section in their settings called “Savengershow,” which many users confuse with desktop wallpaper, but in the MIUI ecosystem and the new HyperOS, the concept has a deeper technical meaning: it is essentially dynamic content that can change automatically, offering not just a static picture, but a whole gallery of images, often tied to a specific time of day or location.
Understanding the difference between static wallpaper and functional screensaver allows you to greatly expand the possibilities of personalizing your device. Instead of spending weeks looking at the same photo, you can set up automatic background changes, get news reports or create artwork directly on a locked screen. It's not just decoration, but a way to make the interface more lively and informative without installing third-party apps.
In this article, we will explore in detail what lies behind this term, how to manage image sources correctly, and where to look for quality files that won’t look stretched or pixelated on your display, explain why standard galleries may not be updated and how to solve this problem.
The difference between the screensaver and the usual wallpaper in MIUI and HyperOS
The first thing that a Xiaomi, Redmi, or POCO user needs to learn is the fundamental difference in the architecture of displaying graphics. Wallpaper is a static image file that you choose manually and attach to your desktop or lock screen. It doesn't change until you decide to replace it. The screensaver in the context of shells from Xiaomi is often a dynamic mechanism or subscription to a service that automatically loads new content.
The screensaver's mechanism is tied to a system service that periodically accesses the company's servers or local gallery, which allows you to implement the "Wallpaper Carousel" feature, where the image changes every time the screen wakes up, and this functionality turns the smartphone into a digital photo frame that shows landscapes, architecture or high-resolution abstractions.
⚠️ Attention: Activation of online screensavers can lead to increased mobile traffic consumption unless a Wi-Fi-only download limit is set.
In addition, the screensavers in Xiaomi firmware often have interactive elements. The lock screen can display time widgets, pedometers or quotes that are integrated into the screensaver layer, rather than the launcher, this creates an effect of depth and layered interface, not available when using simple JPG or PNG files.
Types of screensavers: Carousel, Video and Statics
The personalization system in Xiaomi devices offers several content formats, and understanding their features will help you choose the best option for your use case, the main division is by the type of media file and how it is played.
Static screensavers are a set of high-quality images that can be stored locally in the device's memory or downloaded from the cloud, which is the least demanding of processor and battery resources. Video screensavers, on the contrary, use short videos that are played in a loop. They look spectacular, but require more powerful hardware for smooth playback.

- 🎥 Video wallpaper is a dynamic background with moving elements, often used for the lock screen.
- 🎨 Art collections – special sets from designers, available through the “Themes” app».
- 📸 Personal Gallery – Using your own photos in slideshow mode.
The video wallpaper feature deserves special attention, unlike the standard Android system, where video backgrounds often require third-party live wallpapers. MIUI However, it is worth considering that the constant decoding of a video file even in the background can affect the autonomy of the device, especially on models with a high-performance system. AMOLED-screens where each pixel burns individually.

To save battery power, use video screensavers only on the lock screen, and leave static images of dark colors on the desktop.
How to set up automatic image change
Set up a carousel or auto-saverser change is a simple process, but requires attention to menu details. The interface may vary slightly depending on the firmware version, but the logic remains the same. You will need access to system customization settings.
To start, you need to go to the settings menu. Find the section that deals with the look. In newer versions of HyperOS, the path may look like Settings → Wallpaper and personalization. In older versions of MIUI, it can be a separate Themes app or a item in the general settings called Wallpaper.
☑️ Setting up wallpaper carousel
Once activated, you'll be asked to choose the source of the images, and the system can offer popular categories: nature, cities, technology, art, you can choose multiple categories at once to diversify the visual range, and you can adjust the frequency of the change, whether you turn on the screen or at certain intervals.
The important thing is to manage the cache, because images are uploaded from the network, they take up space in memory, and it is recommended that you periodically clear the cache of the Themes app or the system cache if you notice a slowdown in the interface, which is especially true for devices with a small amount of internal memory.
Where to download quality screensavers for Xiaomi
If standard collections aren’t enough, the Internet offers a huge amount of resources for downloading content. However, it’s important to understand what formats and resolutions your device supports to avoid loss of quality. The optimal resolution for modern Xiaomi smartphones is 1080x2400 pixels and higher, which corresponds to the format of FullHD+ and QHD+.
The official and most secure source is the Themes app, and inside it is the Wallpaper section, where content is moderated, and you can find both free and paid sets from professional designers, and the advantage of this source is that it guarantees compatibility and there is no malicious code.
Third-party resources are also popular among enthusiasts, with dedicated forums and channels where users share screensavers ports from flagship models to older devices. When downloading from unverified sources, beware: files with the.mtz extension (MIUI theme format) may contain scripts.
| Source | Type of content | Security | Requires installation |
|---|---|---|---|
| Annex Topic (Official) | Statics, Videos, Fonts | Tall. | No (embedded) |
| Google Wallpaper | Statics (Pixel, Planet Earth) | Tall. | Yes (via Play Market) |
| Third-party APKs (MTZ) | Modified themes | Medium/Low | Yeah (theme installer) |
| Image-based websites | Static images | Depends on the site. | No (save to the gallery) |
When using third-party launcher or wallpaper widget applications (such as the Wallpaper Engine), make sure they are given the appropriate permissions in the system. Without the right to “Map on Other Windows” or “Autostart”, the dynamic shift will not work.
Problems with loading and displaying content
Users often experience screensavers that stop updating or are not displayed correctly, and the most common reason is the aggressive energy saving policy of the Android system, which simply kills the background process of updating the wallpaper to save charge.
To fix this, you need to find the wallpaper application in the battery settings (often “Themes” or “System UI”) and prevent it from limiting background activity. The path usually looks like this: Settings → Battery and Performance → Application Management → Themes → Autostart. The switch must be activated.
⚠️ Note: If the screensavers are missing after the firmware update, the servers in the region you have chosen may not support this feature.
Another problem may be a lack of space: image cache can grow to several gigabytes. If the device's memory is critically filled, the system will stop downloading new files. Check the free space in the Settings → Memory section and clear unnecessary files.
Sometimes the problem is in the file format. If you downloaded an image in HEIC (standard for iPhone) or WebP, the old version of MIUI may not be able to process it as wallpaper. Convert the file to a universal JPG or PNG before installing.

Effect of dynamic screensavers on the battery
The use of complex visuals does not go unnoticed by the battery. Dynamic screensavers, especially video format, make the processor and graphics accelerator work in enhanced mode, even when the phone is in your pocket and the screen is turned off (when notifications arrive or the phone is raised).
The greatest energy expenditure is seen on AMOLED screens, where pickles are simply turned off to display black. If your screensaver contains many bright, light elements, it results in significant current consumption. Static dark wallpaper, on the contrary, helps to save charge.
There's a myth that live wallpaper discharges a phone in a matter of hours. In reality, modern Snapdragon and MediaTek processors are easy to do, and the rate of increase is about 3-5% per day when used actively, but on low-end models with a small battery, this percentage can be more noticeable.
- 🔋 Optimize – Use dark themes and static images for maximum autonomy.
- ⏱️ Timeout – set up a quick screen damping so that the video screensaver does not work longer than necessary.
- 📉 Upgrade Frequency – Reducing the screen refresh rate to 60Hz will also extend battery life when using animations.
If you notice that the phone has started to warm or discharge quickly after installing a new theme, try turning off the animation feature in the developer settings or go back to the standard static wallpaper for diagnosis.
💡
Balance between beauty and performance: Video screensavers are best used only on the lock screen, leaving the desktop static for energy conservation.
