Owners of Xiaomi, Redmi and Poco devices often face a situation where the once-quick device starts to work slower. MIUI or HyperOS interface hangs, applications open with a delay, and games turn into slideshows. This is not always a sign of breakdown or the need to urgently buy a new gadget. In most cases, the problem lies in software conflicts, cache overflows or incorrect system settings.
An analysis of the Android operating system in the shell from the Chinese manufacturer shows that the brakes are often caused by aggressive optimization of background processes. The system tries to save battery power by forcibly shutting down the programs you need, which when you restart causes a load on the processor. Understanding these mechanisms is the first step to restore the speed of your device without losing data.
In this article, we will take a closer look at the technical causes of slowdown, software cleaning techniques, and hidden features for advanced users: you will learn how to properly manage RAM and ROM, turn off extra animations, and prevent overheating. A comprehensive approach will return the phone to factory sharpness even after several years of operation.
Overflow of internal memory and application cache
One of the most common reasons Xiaomi is slowing down is because internal memory is critically filled, and when the free space in the ROM partition (permanent storage) runs out, the system has no place to create temporary files for swaps and caching operations, which causes even simple actions like typing to start to be executed with a noticeable delay.
The speed of work is particularly affected by overflow of messenger cache. Telegram, WhatsApp and Viber tend to accumulate gigabytes of media files that are not formally necessary for the application to work, but take up space. The MIUI shell has a built-in tool “Cleanup”, but it often acts superficially without affecting the deep folders of the social network cache.
For deep cleaning, you need to manually analyze the storage. Go to the settings and find the partition responsible for memory. The system will show you the usage schedule, where you can see which applications have eaten the most gigabytes. Deleting old videos from the gallery and cleaning the cache of heavy games is a mandatory procedure to maintain performance.
⚠️ Note: When manually cleaning folders through a file manager, do not delete files with the.obb extension or system directories with packet names (for example, com.android...) unless you are sure about their content.
There's an effective way to speed up formatting, and if you haven't done a complete reset in a long time, the fragmentation of the file system could have reached a limit, and copying important data to a computer and then resetting it to factory settings often works wonders, bringing the phone back out of the box.
- 📱 Check the Download folder regularly by removing installations. APK-file.
- 🗑️ Use the Deep Clean function in the standard Security app".
- 📸 Move photos and videos to the cloud or to your computer, freeing up local space.
💡
Free space less than 10% of the total memory is guaranteed to cause micro-freezes of the interface and slow down the camera.
Aggressive battery optimization and background processes
The philosophy behind MIUI and the new HyperOS is to maximize energy savings, and the algorithms ruthlessly kill background processes that AI believes are not in use right now, but this often backfires: when you go back to an application, it loads again, consuming the peak CPU life, which is perceived by the user as lag.
The problem is compounded by heavy apps that start right after the phone is turned on, creating a queue of requests to the CPU, and in the first minutes after the smartphone is turned on, animations can slow down, and sensor response can be delayed, and you need to manually adjust the behavior of each important application.
To solve this problem, you need to go to the battery settings and find a specific application. Change the energy saving mode from "Saving" to "No restrictions." This will allow the program to work in the background fully. It is also worth turning off "Memory Extension" on older phones, since using part of the ROM as RAM (virtual memory) often works slower than the physical and causes interface jerks.
Settings → Applications → All Applications → [Select App] → Battery → No LimitationsAnother hidden resource eater is advertising in system applications. msa (MIUI System Ads) is constantly hanging in memory, waiting for commands to display ads, and turning it off significantly reduces the load on the processor in the background.
- 🔋 Turn off "Memory Extension" in the "Advanced Settings" section if you have less than 6 GB of RAM.
- 🚫 Turn off ads in password and security settings to stop the msa service.
- 🔄 Reboot your phone at least once a day. 3-4 day to reset accumulated errors in memory.

Impact of MIUI and HyperOS Updates on Performance
Often, users notice that the phone started to brake immediately after the arrival of the update system. MIUI/HyperOS The system indexes files and optimizes databases during this period (usually during the process). 2-3 The phone can warm up and work slowly.
However, sometimes the update does contain software bugs that are not optimized for a particular Snapdragon or MediaTek processor model. In such cases, the lags can be observed constantly. Check the forums and feedback from other users of your model: if the problem is massive, it may be worth rolling back to the previous version of the firmware or waiting for a patch.
It is important to distinguish between scheduled optimization and crash. If more than a week has passed since the update and the phone is still unstable, try clearing the system partition cache. This is secure and will not delete your personal data, but will reset temporary update files.
| Android version | Optimization type | Duration of deceleration | Recommendation |
|---|---|---|---|
| Android 11 → 12 | Complete re-indexation | Up to 48 hours. | Leave on charging at night |
| MIUI 13 → 14 | Renewal of libraries | 12-24 hour | Active use |
| HyperOS (Beta) | Unstable assembly | Constantly. | Firmware rollback |
| Security patch | background | Not too much. | Not required |
If you use a beta version of firmware, remember that it is not designed for everyday stable use. bugs in code can cause memory leaks and endless service restart cycles, which directly affects the response rate of the screen.
Animation and Visual Effects Settings
Beautiful graphics are Xiaomi’s calling card, but they require graphics accelerator resources. If your smartphone doesn’t have flagship hardware, complex transitions between windows can cause frame-per-second (FPS) drops. Visually, it looks like slowing down when swiping and opening menus.
In the developer section, you can find the animation scale settings. The standard value is 1x. Reducing this to 0.5x or completely turning off animation makes the interface visually sharper and faster. The phone starts to respond to touches instantly, since the system does not need to waste time drawing transitions.
Also worth noting is wallpapers and widgets. Live Wallpapers and widgets with constant content updates (weather, news) load the processor every second, and replacing them with a static image is an easy way to reduce the load on the GPU.
Settings → About Phone → (7 times click on the version of MIUI) → Advanced settings → For developers → Animation Scale⚠️ Warning: Disabling animations completely can make the interface less understandable, as the visual link between the window transitions will be lost. 0.5x.
- 🎨 Use static wallpaper instead of living.
- 📉 Reduce the scale of window animation, transitions and animator duration.
- 🗑️ Remove unnecessary widgets from your desktop, especially those that require internet access.
💡
Turn on Game Turbo, even for regular applications, if they are slow, and this will force them to devote more CPU resources.
Hardware limitations and processor overheating
You can't discount the physical condition of the device. Trottling is a mechanism to protect the processor from overheating. When the core temperature reaches a critical point, the system forcibly reduces the frequency of the processor, at which point the phone starts to brake terribly to cool down, which often happens when you use the navigator in the sun or while charging.
Battery wear also affects performance, and if the battery is degraded and can't deliver the right current at peak load times, the processor goes into energy-saving mode, even if the charge is formally high.
In addition, cheap chargers can give unstable voltage, which causes interference in the touchscreen (so-called "phantom presses" or loss of sensitivity).
- 🌡️ Remove the case while charging or playing to improve heat sink.
- 🔌 Use only original or certified cables and charging units.
- 📉 Avoid using navigation in bright sun without additional cooling.
Hidden debugging features for advanced users
For those who aren't afraid to experiment, there are deeper optimization methods, and there's a "Do Not Activity" item in the developer menu, and if you turn it on, the system will completely unload the application from memory as soon as you fold it, which will free up maximum RAM, but when you return to the application, it will boot again, which can be inconvenient.
You can also limit the number of background processes. The default is "Standard Limit," and setting a limit to, say, 2 or 3 processes will make the system more tightly control multitasking, which is useful for older models with 3-4 GB of RAM.
☑️ Checklist of fast optimization
Another nuance is to disable unused Google services or system components via ADB (Android Debug Bridge), which requires a connection to a computer but removes the bloatware that cannot be removed in the usual way.
adb shell pm disable-user --user 0 com.google.android.videosBe careful, however: disabling critical system packages can result in a cyclical bootloop.Always check the destination of the packet before removing or freezing it.
