Modern smartphones like the Xiaomi Redmi 9 offer users not just utilitarian features, but deep interface personalization. One of the most striking and dynamic features of the MIUI system is a wallpaper carousel that automatically changes the background image on a locked screen every time a device wakes up. This turns the usual notification check process into visual pleasure, allowing you to see hundreds of quality photos of nature, architecture or abstract art.
However, despite the popularity of this feature, many owners face difficulties in its initial activation or subsequent configuration. Often users can not find hidden switches in the menu, or the system blocks the service due to aggressive optimization of power consumption. In this article, we will discuss in detail each step necessary to ensure that the wallpaper carousel works on your gadget consistently and without errors.
We will not only look at the standard way of turning on, but also the nuances of working with the theme of the design, which is a prerequisite for the functioning of the slideshow, and will also address the issues of battery saving, since the constant download of images over the network can affect the autonomy if you do not configure the settings correctly.
Compatibility check and basic requirements
Before you go into the settings, make sure your Redmi 9 software is ready to work with multimedia content.The carousel function is closely integrated with the system components of MIUI, and it requires an up-to-date firmware version to work correctly.Outdated builds may not contain the necessary libraries or have bugs that prevent images from loading.
It is important to understand that the wallpaper carousel is not just a set of pictures, but a full-fledged service that requires Internet access and system permissions. Without a stable connection to the global network or Xiaomi Chinese servers (depending on the region of the firmware), the tape may not be updated. Make sure that the device is on data or connected to the Wi-Fi network.
⚠️ Note: If you use a custom theme other than the standard one, the carousel function may be forced off by the theme developer.
Also worth checking is the availability of free storage space in the device. The image cache can take up a significant amount of space, especially if you plan to store hundreds of high-quality images in a buffer.
Activation through the “Themes” app
The main visual style management tool in the Xiaomi ecosystem is the pre-installed Themes app, which is where the master switch that triggers the image change mechanism is hidden. The switching process requires several actions to be performed consistently, since the option is not always in sight.
First, open the Themes app on the home screen or in the Tools folder. In the lower right corner, you'll see the profile icon(s) clicking on it will open your account menu and personalization settings, and you'll need to find an item that could be called Wallpaper Carousel or Wallpaper Carousel.
Once you go to the menu, the system may suggest you download an additional data packet or update the service component. Accept installation, as this is a critical module. Then activate the wallpaper carousel slider. From now on, when you lock the screen, the images will start to change.
☑️ Activation checklist
If the lock screen remains the same after the slider is turned on, try unlocking and locking the device several times.Primary booting can take time, especially if the network connection is unstable.Rebooting the smartphone also often helps to apply changes if they do not take effect instantly.
Configure update parameters and categories
Once the basic function is successfully activated, a wide range of settings are available to the user to adapt the service to their personal preferences. Standard settings may not suit everyone, so the system provides flexible content management tools.
In the carousel menu, you'll find the "Refrequency" section, where you can choose how often the image will change: at each lock, once per hour, once per day or when you connect to a charge. For maximum visual diversity, select "At each lock" mode, but this can increase traffic consumption.
Category filtering is also available, and you can eliminate unnecessary topics, like leaving only "Nature" and "City" by removing "Abstraction" or "Technology," through the subscription management menu inside the carousel section.
| Setup parameter | Description of function | Impact on the battery |
|---|---|---|
| Frequency: Lockdown | Change the picture with each screen quenching | High. |
| Frequency: Daily | One new image per day | Low. |
| Only Wi-Fi. | Content uploading only via wireless network | Average. |
| HD quality | Uploading images at maximum resolution | High (traffic) |
Keep in mind that the high-resolution (HD) option consumes more mobile traffic. If you have a limited plan, it’s best to activate the download option only via Wi-Fi.

Solving loading and display problems
Quite often, users are faced with a situation where the feature seems to be on, but the images do not change or are displayed with errors, this can be caused by permission conflicts or system restrictions, first of all, check whether the Themes application and Carousol service have permission to access the network and storage.
Go to Settings → Apps → All apps. Find Wallpaper Carousel on the list. Go to Permissions and make sure that you have access to Storage and the Internet. Without memory, your phone won't be able to save new images for display.
The second common cause is aggressive energy saving, and MIUI is known for its tight control of background processes, so if the system puts the carousel to sleep, the new images stop loading, you have to lock the app in memory.
- 🔋 Open the menu of running applications and find the “Themes” or “Carousel” window».
- 🔒 Press and hold your finger on the window, then select the lock icon to prevent cleaning.
- ⚙️ In the battery settings, select the "No Limits" mode for system design components.
⚠️ Attention: Cleaning the cache of the Themes app can reset all carousel settings and delete uploaded images. Use this feature only if the carousel is running with critical errors.
If problems persist, try resetting the app itself through the storage menu, but keep in mind the consequences. Sometimes switching the system language to and from English helps, which restarts some system services.

Use the Preview feature in the carousel settings to see exactly how your slideshow will look before applying the changes to all lock screens.
The impact of the carousel on the autonomy of Redmi 9
Owners of Redmi 9, which features a MediaTek Helio G80 processor and a 5020 mAh battery, often wonder about the impact of dynamic wallpaper on the time of operation. Although the screen is the main consumer of power, the constant activity of the processor for decoding images and the communication module for downloading them contributes to the overall consumption.
The greatest energy expenditure occurs when a new image is uploaded on the mobile network and when it is rendered on the display. If you use the “on lock” change mode and check your phone often, the consumption can be noticeable. In the “daily” or “on charging” modes, the impact on autonomy is minimal and almost invisible in other applications.
For optimization, it is recommended to use Wi-Fi to download content. 4G/LTE It will not be activated to download data, which will save charge, and you should also avoid using live wallpaper at the same time as the carousel of static images, as this will create a double load on the graphics accelerator.
Analysis of battery statistics in the settings will show the real percentage of consumption. If System UI or Themes consume more than 5-7% of the charge per day, it is worth reviewing the frequency of updates or disabling the boot in high resolution.
Alternative ways to personalize the screen
If Xiaomi’s standard carousel doesn’t fit you for some reason or seems too limited, there are third-party solutions.The Google Play Store offers a variety of apps that can replace system functionality, giving you access to millions of images from a variety of sources.
Popular launchers and widgets allow you to create complex scenarios of background change. However, it is worth remembering that third-party applications require wider resolutions and may work less stable in the background due to the optimization of MIUI. System carousel still has the advantage of deep integration.
For those who want maximum performance, you can use static wallpapers of high quality, they don't use the CPU to decode, they don't require an Internet connection, and the choice between performance and efficiency is left to the user.
💡
System wallpaper carousel is a balance between visual appeal and optimization, as it is built into the core of the system and does not require the installation of additional heavy software.
In conclusion, setting up the carousel on Redmi 9 is a simple but effective way to bring the interface to life. By following the recommendations for setting resolutions and energy saving, you will get a beautiful lock screen without compromising the performance of the device.
