Xiaomi smartphone owners often face a situation where a once-quick device suddenly starts to work slowly. MIUI or HyperOS interface slows down, apps open with a delay, and games turn into slideshows. This phenomenon, known as friezes or lags, can be caused by a variety of factors, from overflowing memory to software conflicts.
There is a misconception that you can speed up your phone only by resetting to factory settings, but this is not always the case. Often it is enough to properly optimize the system, disable unnecessary services or clean the cache of system processes. In this article, we will look at proven methods that will help return the performance of your device without radical measures.
Before we get to the tricky part, we need to understand the nature of the problem, because the brakes can be caused by physical wear and tear on the drive, overheating of the processor or a trivial lack of RAM, and we can analyze the situation to choose the most effective way to solve it.
Analysis of the causes of braking of the system
The first step in the struggle for performance is diagnostics. MIUI has built-in monitoring tools, but they don't always show the full picture. Often the user doesn't notice how background processes eat up all the CPU resources. You need to check which applications consume the most power and memory.
One of the main reasons is that internal memory overflows, and when disk space runs out, data write and read speeds drop dramatically, especially for eMMCs, which are often installed in budget smartphones, and if you have more than 90 percent of the memory, the lags are almost guaranteed.
Age is also important, as the database of contacts, messages and call logs grows over time, slowing down system services, and app updates may not be optimized for the old hardware.
- 📉 Check the storage capacity in the menu "About the phone».
- 🔋 Analyze the battery consumption in the section "Safety».
- 📱 Pay attention to the heating of the body during simple work.
- 🔄 Think about the last time the firmware was updated.
💡
Use the built-in Security → Cleanup app to quickly diagnose major memory and cache problems.
Memory Cleanup and Storage Optimization
Freeing up space is a base. Delete unnecessary files, duplicate photos and old downloads. MIUI has a useful garbage cleanup feature, but it doesn't always remove the cache of heavy apps like Telegram or Instagram. These programs need to be manually cleaned through their internal settings.
It's important not just to delete files, but also to structure the remaining data. Moving photos and videos to the cloud or to the computer will significantly offload the system, and it's also worth removing unused applications that may have background services.
☑️ Cleaning up memory
There is a hidden feature in the developer menu that allows you to force the background processes to close, but you need to use it with caution, and a constant reboot of services can, on the contrary, increase battery consumption.

Customization of animations and MIUI interface
The visuals of Xiaomi’s shell are beautiful, but resource-intensive. Transition animations, window openings, and app folding put a strain on the GPU; reducing the scale of animations or turning them off completely will visually speed up the interface.
To access these settings, you need to activate the developer mode, and this is done by repeatedly clicking on the build number in the About Phone menu, and then the Developer option will appear in the advanced settings.
In this section, we are interested in the parameters of "Scale of window animation", "Scale of transition animation" and "Scale of animator duration." Changing the value from the standard 1x to 0.5x or Disabled makes the system response instantaneous.
| Parameter | Standard value | Recommended value | The effect |
|---|---|---|---|
| Window animation | 1x | 0.5x | Quickly open applications |
| Animation of transitions | 1x | 0.5x | Instant screen switching |
| Duration of the animator | 1x | Out. | Removes delays in input |
⚠️ Warning: Completely disabling animations can make the interface less pleasant and sharp to perceive, try the value first 0.5x.
Disabling Advertising and System Garbage
MIUI advertising services (MSA) consume Internet traffic and processor resources even in the background, and turning off ads will not only remove pop-ups, but also reduce the load on the system, which is especially important for budget models.
To remove ads, you need to disable msa from the Passwords & Security menu → Access to Personal Data. It is also recommended to disable receiving recommendations in the settings of each system application separately.
Also, it’s worth checking for auto-run applications, many programs are prescribed to boot without the user’s knowledge, and limiting auto-runs to unnecessary services (such as marketplaces or games) will free up RAM immediately after the phone is turned on.
- 🚫 Shut down the service. MSA privacy settings.
- 📵 Ban Auto-Run for Social Media and Gaming.
- 📉 Turn off “Get recommendations” in the themes and security settings.
- 🔍 Turn off personalized ads in your Mi Account.
💡
Disabling system advertising is not only comfort, but also a real way to save battery power and processor resources.
Using Developer Mode for Gamers
For mobile gamers, MIUI features a special Game Turbo, but there are hidden settings that can improve performance in specific scenarios, and the developer menu features the option of Accelerate Graphics Performance (4x MSAA), but it can lead to increased heat.
Also, you should pay attention to the limitation of background processes, if you play a heavy game, you can temporarily set the limit of background processes to "No more than 2", which ensures that all resources are given to the game.
If the hardware doesn’t pull the game, software crutches can lead to unstable performance.
adb shell settings put global window_animation_scale 0.5
adb shell settings put global transition_animation_scale 0.5
adb shell settings put global animator_duration_scale 0.5⚠️ Attention: Enabling the option 4x MSAA It can cause a quick discharge of the battery and overheating of the device in the summer.
Cardinal measures: Resetting and flashing
If software optimization doesn't work, the last resort is a full reset to factory settings (Wipe Data), which will delete all user data, so you need to back up beforehand. Reset eliminates file system errors and conflicts accumulated over the years of use.
In some cases, flashing the device to an easier build or returning to a stable version of the software if the current version is a beta version helps, but firmware through Fastboot requires caution and the presence of an unlocked bootloader.
Before reset, make sure that the battery is at least 60%. interruption of the reset process can make it impossible to turn on the phone (brick).
