If you own a Xiaomi smartphone, you've probably noticed that there are two sections in the customization settings: "Themes" and "Wallpaper." At first glance, it may seem like they're the same thing -- just different ways to change the look of the phone. But in fact, these features are radically different in terms of capabilities, depth of customization, and even the impact on the performance of the device.
In this article, we will discuss in detail what the topics are. MIUI They differ from traditional wallpapers, how they work under the hood of the system, and why the choice between them depends not only on aesthetic preferences, but also on the technical nuances of your Redmi, POCO You'll also learn how to avoid common mistakes when setting what resources they consume, and why some wallpapers can eat up battery life faster than others.
Before we jump into the comparison, let's be clear: if you want to just change the background on the lock screen or desktop, you'll have enough wallpaper. If you want a complete interface transformation (icons, fonts, animations, sounds), then you can't do it. And here the pitfalls begin...
1. Wallpaper on Xiaomi: what it is and how it works
Wallpaper (or background images) is the most basic element of smartphone customization. They are static or dynamic images that are displayed on:
- 📱 Desktop (where application shortcuts are located)
- 🔒 Lock screen (including the option with the clock)
- 📂 Inside folders (in some versions) MIUI)
In Xiaomi wallpaper is divided into three types:
- Static -- normal pictures (JPG, PNG) with a resolution adapted to the smartphone screen.
- Dynamic (Live Wallpapers) – animated background images that respond to gestures (for example, the paralax effect when tilting the phone).
- System - wallpaper by default from MIUI, Optimized for a specific model (for example, Xiaomi 13 Ultra or POCO F5).
The main advantage of wallpaper is its lightness, it doesn't really load the processor, it doesn't use any extra energy (except for the dynamic options), and you can set the wallpaper in a number of ways:
- 🖼️ Through the gallery: select a photo → "Set up how" → "Wallpaper"
- 🎨 Through Settings. → Wallpaper (available collections from Xiaomi)
- 🌐 Download from Google Play (apps like Wallpapers Craft or Zedge)
⚠️ Attention: Dynamic wallpaper with 3D-effects (e.g., "Ocean" or "Space" in the MIUI) They can increase battery consumption by 5 to 15 percent because of the constant operation of the graphics accelerator. If you notice that the phone has become more discharged, check if such a background is installed.
2. Topics MIUI: deep-customization of the interface
Themes in Xiaomi are not just background pictures, but full-fledged design packages that change:
- 🎨 Application icons (form, color, style)
- 🔤 Fonts (including system fonts)
- 🎵 Notification sounds and signals
- 🖥️ Style of menus and panels (color of status bar, navigation buttons)
- ⚡ Animations of transitions between screens
Unlike wallpaper, themes require installation through the official Themes app (available in Settings). → Themes or as a standalone app. They are downloaded from Xiaomi’s cloud storage, which features thousands of options ranging from minimalist to futuristic.
It is important to understand that themes may conflict with some system applications, especially if they are poorly optimized, for example, after installing dark design in some versions. MIUI 14 Users Complain Unreadable Text on Google Chrome or WhatsApp Due to Overlaying Color Schemes.
| Parameter | Wallpaper. | MIUI themes |
|---|---|---|
| Depth of change | Only the background. | Icons, fonts, sounds, animations |
| Impact on productivity | Minimum (except Live Wallpapers) | Average (depending on the complexity of the topic) |
| Battery consumption | Low. | Low to High (Animated Themes) |
| Source of installation | Gallery, third-party annexes | Official Annex Topic |
| Compatibility | Universal (works on any Android) | Only for MIUI (They may not support older versions) |

3. How wallpaper and themes affect productivity

- ⚡ Dynamic (Live Wallpapers) use OpenGL or Vulkan to render animation, which can be loading. GPU 10-30% in the background.
- 🔋 Nana AMOLED-In the case of the Xiaomi 12 Pro, dark wallpaper reduces battery consumption because the pixels are simply turned off.
Topics:
- 🖥️ Simple themes (Icons only) + fonts) have little impact on productivity.
- 🎭 Complex themes with animations, transparency and effects can add to the load on the environment. CPU 15-20%, especially on budget models (Redmi) 9A, POCO M3).
- 🗑️ Some themes set additional services in the background (for example, to change wallpaper time of day).
To check how the theme or wallpaper affects your Xiaomi, open Settings → Battery → Use the battery and see how much power the com.android.systemui process (responsible for the interface) or the Wallpaper/Themes app consumes.
