Owners of Xiaomi, Redmi and POCO smartphones often experience a sense of “sluggishness” of the interface, especially on budget models or after updating the MIUI and HyperOS firmware. One reason for the subjective slowdown is the standard duration of transitions between screens, known as window animation. By default, it is set to 100% or even 150%, which is designed to make interaction with the gadget smoother and more pleasant for the eyes, but this time takes precious fractions of a second with each action.
Changing animation settings is a proven way to visually speed up your smartphone without having to get root rights or complex flashing. Android allows you to flexibly adjust the speed of rendering transitions, and in the shells from the Chinese manufacturer this feature is hidden in a special engineering menu. Understanding how this mechanism works will help you adapt the device to your own usage habits.
In this article, we will take a closer look at what Xiaomi’s window animation is all about, where to find hidden settings, and what values are optimal for different use cases. You’ll learn to balance visual smoothness with maximum responsiveness, making your smartphone faster.
What is window animation and how does it affect MIUI?
Windows animation in the context of the Android operating system is a visual effect that is played when you open, close or fold applications, as well as when you switch between desktops. When you click on an icon, the system does not instantly show the content, but smoothly stretches the window image, a process controlled by a system timer that is set in milliseconds or percentages.
On Xiaomi devices with MIUI shell or the new HyperOS, these effects are implemented quite aggressively. The company’s engineers are betting on beauty and smoothness, believing that abrupt transitions will annoy the user. However, in practice, especially on models with entry-level processors (for example, the Redmi Note series or Poco M), long frame rendering creates a sense of lag and input delays.
⚠️ Attention: Complete shutdown of animation (value) 0x) It can make the interface twitchy and less understandable, because the visual link between the action and the result disappears. It is recommended not to remove the effects completely, but only to reduce their duration.
By changing this setting, you are effectively telling the system, “Don’t wait for the standard time to complete the transition, consider the window open right away.” This does not increase the performance of the processor directly, but significantly reduces the waiting time for the interface response, making use of the smartphone more comfortable and faster.
Where to find a hidden developer menu on Xiaomi
Before making changes, you need to access the hidden settings section. In the standard About Phone menu, these options are not available to protect against inexperienced actions. The activation process is the same for all current models, whether it is the flagship Xiaomi 14 or the budget Redmi 13C.
You will need to perform the following sequence of actions:
- 📱 Open the Settings app and go to the About Phone section».
- 👆 Find the line "Version" MIUI» (or "Version" OS» in HyperOS) and quickly click on it 7-10 successively.
- ✅ Wait for the pop-up notification “You became a developer!».
- 🔙 Return to the main settings menu, scroll down and select “More».
- ⚙️ In the list, find the item “For developers».
Once you log in, you'll see a lot of technical options. Don't be afraid of the setup, we're only interested in the specific subsection that renders the interface. Be careful, changing the other parameters in this menu can lead to unstable system operation.
💡
If the “For Developers” item disappeared after the reboot, just repeat the procedure with taps according to MIUI version – this is normal for some versions of the firmware.
Setting the speed of animation: step-by-step instructions
Inside the developer menu, you'll find a setup that's associated with drawing, which is usually at the top of the list or in the middle, depending on the Android version, and we're interested in three key settings that work together.
☑️ Checking the animation settings
The first thing you need to do is find the line "Window animation scale," which is the parameter that controls the speed of opening and closing applications, and the next one is usually "Scale of transition animation" (change desktops) and "Duration of animation" (general system effects).
For optimal operation, it is recommended to set the following values:
- 🚀 0.5x — «The middle ground.The interface gets noticeably faster, but the animations remain fluid and invisible to the eye.
- ⚡ 0x (Off) — Top speed. Animations disappear, windows open instantly. It's good for older devices, but it looks a little sharp.
- 🐢 1.5x or 2x — Slowing down. It's rarely used, for example, to demonstrate the interface or to people with special perceptions.
To change the value, click on the appropriate line. In the list that appears, select the desired ratio. The changes take effect instantly, you don't need to restart the device. You can experiment with settings in real time, opening and closing the menu to find the perfect balance.
Comparison of scaling options
Different users prefer different settings depending on their habits and the power of the smartphone. Below is a table that will help determine the optimal value for your use case.
| Meaning | Visual effect | Impact on speed | Recommendation |
|---|---|---|---|
| 1x (Default) | Standard MIUI smoothness | Basic | For the new flagships |
| 0.5x | Quick, but smoothly. | Tall. | Optimal for everyone |
| 0x (Offline) | Abrupt transitions, no effects | Maximum | For old devices. |
| 1.5x | Slow motion | Low. | For a demonstration |
As you can see from the table, 0.5x is the most versatile solution to speed up the system while maintaining the aesthetics of the interface that Xiaomi designers worked on. Setting a value of 0x can be useful on devices with a memory capacity of 2-3 GB, where every millisecond counts.
The Impact of Animation on Performance and Battery
There's a common myth that turning off animations saves a lot of battery power, and in practice, the effect of this parameter on power consumption is minimal. A graphics processing unit (GPU) spends negligible amounts of energy rendering simple interface transitions compared to a screen, a communication module, or background processes.
But the impact on subjective performance is huge: When animations last 100-200 milliseconds instead of 500, the user gets a response faster, and it creates a sense of a lively and powerful device. On older models like the Redmi 9 or Poco X3 NFC (after years of use), this can extend the comfortable life of the gadget.
⚠️ Note: If the interface starts to work unstable after changing the settings or the applications fly out, just return the scale value to the 1x. It is a software setup that cannot physically damage the device, but can cause software conflicts in rare cases.
Also, you have to consider that in the HyperOS shell, the rendering algorithms have changed, and here the animations are tied to the refresh rate of the screen. If you have 60 Hz mode on, even at a 0.5x scale, the transitions may seem less smooth than 120 Hz.
Frequent problems and their solution
Sometimes users are faced with a situation where a zoom change does not give a visible result or settings are reset, this can be due to the features of a particular firmware version or a conflict of design themes.
Let us consider the main reasons:
- 🎨 Some of the themes from the store. MIUI Themes have their own hard-coded animation options that overwrite system settings. Try to bring back a standard theme.
- 🔄 System errors. Once the software is updated, the developer's settings may be reset.
- 📱 Device model: Some global firmware versions may have menu items that are called differently or hidden deeper.
What to do if the developer menu is gone?
In the rare cases where standard methods fail to speed up, you can use ADB commands, but this requires a computer connection and basic debugging knowledge. For most users, it is enough to set up via the phone menu.
💡
Changing the scale of animation is the safest and most effective way to speed up the Xiaomi interface without losing the warranty and risk of “bricking” the device.
Additional tips for optimizing the interface
In addition to windows, there are other speed-impacting options on the developer menu, such as limiting background processes, but you shouldn't touch them unless you absolutely have to, because it can disrupt messengers and notifications.
It is better to focus on cleaning memory and removing unused applications, which, in conjunction with accelerated animation, will give the best result, and it is also recommended to regularly restart the smartphone, especially after installing major system updates.
Remember, visuals are a matter of taste. If you like how smoothly windows float on standard settings, there's no point in changing them just to chase numbers in benchmarks.
💡
Use desktop widgets with caution. Live wallpaper and heavy weather widgets can negate all efforts to speed up animations by loading the processor in the background.
