The lock screen of the Xiaomi Redmi 9T with dynamically changing wallpaper can be annoying — especially when the background automatically updates after each unlock or after a certain period of time.This feature, built into the MIUI shell, is often activated by default after updates or when using themes from the Mi Themes store. Unlike static wallpapers, dynamic backgrounds not only consume additional energy, but can also slow down the unlock animation on budget models like the Redmi 9T.
Complicating the problem, some versions of MIUI 12.5-14 have hidden or no deactivation options in the menu, and users are faced with a situation where, after changing the theme or resetting the settings, dynamic wallpaper returns without being able to remove them through the usual interface. In this article, we will discuss all working methods, from official to alternative, including editing system files for power users.
Why do Redmi 9T have changing wallpapers?
Dynamic wallpaper on the lock screen Xiaomi Redmi 9T is part of the functionality of the shell MIUI, which automatically loads the backgrounds from several sources:
- 🎨 Themes from Mi Themes: Many free and paid themes include animated or cyclically-changing wallpapers. Even if you have a static theme, some elements (such as the lock screen) may remain dynamic.
- 🔄 Super Wallpapers: Xiaomi’s built-in “super wallpapers” (such as space or Earth) have animations and a change of angles by default when unlocking.
- ⚙️ Settings MIUI Launcher: In some firmware versions, the wallpaper change option is tied to the launcher, not to system settings.
- 📱 Updates: After major updates MIUI (For example, from 12 to 13) wallpaper settings can be reset, and the system again activates dynamic backgrounds.

Budget devices don’t support smooth animations from Super Wallpapers, so instead it uses a simplified version – changing static images at fixed intervals (usually once every 1-12 hours), which creates the illusion of “dynamicity”, but in practice just loads the processor and consumes battery power.
