How to change the desktop on Xiaomi Poco X3: from standard wallpaper to custom launchers

Xiaomi Poco X3 — One of the most popular smartphones of the budget segment, but even its owners do not always know how to customize the interface as much as possible. MIUI offers much more opportunities than it seems at first glance: from simple change of wallpaper to installation of third-party shells with a 3D-In this article, we'll look at all the ways that you can transform the home screen, from basic settings to advanced tricks that aren't written in the official manuals.

Many users are limited to standard gallery wallpaper, but the Poco X3 based on MIUI 12/13/14 supports dynamic themes, live wallpaper, scrolling animation and even smooth transition between desktops. Moreover, with the help of third-party applications (like Nova Launcher or Hyperion Launcher), you can completely remake the appearance of the system by adding gestures, hidden folders and adaptive icons. We will tell you how to do this without risk “breaking” the phone, and share life hacks to optimize performance after changes.

How to change the desktop on Poco X3: from simple to complex

To start with the basic methods that are available out of the box, MIUI offers several desktop customization options, and most of them don't require additional applications to be installed.

• 🖼️ Standard wallpaper change - through the theme settings or gallery. Supports static and live wallpaper (in format.mp4 or.gif).
• 🎨 Topics MIUI — Ready-made design packages that change icons, fonts, even transition animations.
• 🔄 Reset layout – return to the factory settings of the location of icons and widgets (useful after experiments).
• 📱 Third-party launchers – a complete replacement for the standard shell (Nova Launcher, Lawnchair, Microsoft Launcher).

Each method has its pros and cons. For example, live wallpaper looks beautiful, but can increase battery consumption by 10-15% (according to tests on the Poco X3 with MIUI 13). On the other hand, third-party launchers give more freedom, but sometimes conflict with Xiaomi’s proprietary features (for example, with Second Space or App Lock).

Step-by-step: how to change the wallpaper on the desktop

The easiest way to refresh the look is to change the background pattern. In MIUI, this is done in two taps, but there are nuances with resolution and file formats.

1. Open Settings → Desktop or make a long press in the free place of the main screen.
2. Select the Wallpaper (or Themes) item → Wallpaper, if you use a custom theme).
3. Scroll down to My Wallpaper section – all images you upload will be displayed here.
4. For live wallpaper, go to the Dynamic tab and select animation (e.g. Ocean or Space).
5. Click Apply and specify where you want to change the background: on the desktop, Lock screen or both.

It is important to consider the Poco X3's screen resolution of 2400×1080 pixels (an aspect ratio of 20:9). If you use wallpaper with lower resolution, it will stretch, which will lead to loss of clarity.

• 📏 Download the wallpaper in format 2400×1080 or higher, for example, 4K, but with a pruning ratio).
• 🖼️ For live wallpaper files are suitable.mp4 permittingly 1080p and bitrate not higher than 5 Mbit / s (otherwise lags are possible).
• 🔄 If the wallpaper isn’t fitting in size, use the Wallpaper Engine app (there’s a free version) to trim.

⚠️ Warning: If you have artifacts (blurring, stripes) on your lock screen after changing the wallpaper, try turning off the background blur option in the theme settings. This feature automatically applies the blur effect to the wallpaper, which can spoil the quality in some images.

Installation of third-party launchers: Nova Launcher and alternatives

The standard MIUI launcher is limited in settings: you can't resize icons, remove Google's search bar, or add gestures. The solution is to install an alternative shell. The most popular options for Poco X3 are:

To install a third-party launcher:

1. Download an app from Google Play (like Nova Launcher).
2. After installation, click Home and select a new launcher as the main one (the system will prompt you to do this automatically).
3. In the launcher settings (Long press → Settings) configure:

⚠️ Note: When using Nova Launcher on MIUI 14 may lose access to the Control Center (swipe down). To return the function, turn off the Enable Immersive Mode option in the launcher settings.

💡

If the application icons are missing after installing the launcher, restart the phone. MIUI sometimes resets the launcher cache on the first run.

Dynamic themes and hidden MIUI functions for desktop

MIUI hides a lot of options that are not obvious at first glance, like the smartphone has a built-in feature that automatically changes wallpaper depending on the time of day or the weather, to activate it:

1. Go to Settings → Desktop → Dynamic Wallpaper.
2. Select a theme marked Auto (e.g. Sunrise to Sunset).
3. Set up a schedule or tie it to weather conditions (access to geolocation is required).

Another useful feature is hidden gestures for the desktop. These can be included in Settings → Additional → Gestures:

• 👆 Swipe up – opening the application menu (analogue of the button All applications).
• 👇 Swipe down – quick search (works only with branded launcher).
• ➡️ Double swipe to the right – switch to the previous desktop (if there are several of them).

For advanced users, there's a way to change the animation of the transitions between screens.

1. Activate Developer Mode (7 times click on the MIUI version in your phone settings).
2. Go to Settings → For developers and find options:

Optimizing performance after the launcher change

Third-party launchers and live wallpaper can slow down the Poco X3, especially if the phone has been in use for a year or two.

• 🔋 Limit background launcher activity in battery settings (Settings) → Battery → Optimization).
• 🗑️ Clear the launcher cache once a week (in the app settings).
• 📉 Disable unnecessary widgets – they constantly update data in the background.
• 🔄 Use Easy Mode in Nova Launcher (Settings) → productivity).

If after installing the launcher, the phone began to overheat, check:

1. Is 120Hz animation for live wallpaper included (this puts a lot of work on the processor).
2. Whether the theme is used with transparent elements – they require additional processing of the GPU.
3. Are there other “heavy” applications running in the background (for example, games or video editors).

To check the load on the system, use the CPU Monitor application or the built-in performance monitor in MIUI (Settings → About Phone → System Status). If the CPU load exceeds 50% in idle, this is an excuse to return the standard launcher.

💡

Live wallpaper and animations can reduce battery life by 1-2 hours. If the battery is draining too quickly, go back to static wallpaper or turn off dynamic effects in the theme settings.

How to return a standard desktop if something goes wrong

If after experimenting with launchers or themes, the interface began to work incorrectly (for example, icons disappeared, applications did not open or artifacts appeared), you can return everything back in two ways:

Method 1: Through the MIUI settings

1. Go to Settings → Applications → Application Management.
2. Find the current launcher (like Nova Launcher) and click Clear Data.
3. Return to the home screen and select the standard MIUI launcher as the primary.

Method 2: Resetting the desktop settings

1. Make a long press on the desktop and select Desktop Settings.
2. Scroll down and press Reset layout.
3. Confirm the action – all icons and widgets will return to factory settings.

⚠️ Note: If you have used Second Space (Second Space) MIUI), Resetting the launcher can cause you to lose settings in both profiles.Before resetting, make a backup through Settings → My device. → Backup.
