Modern Xiaomi smartphones, which are based on the shells MIUI or the new HyperOS, have huge potential, but over time, even flagship models can start to work slower. The accumulation of system debris, background processes and proliferation of app cache are natural processes that inevitably affect the response of the interface. Users often notice that after a year or two of active use, the device begins to open programs longer or slow down in games.
However, it is too early to rush to replace a gadget or to reflash a complex one. In most cases, the situation can be radically corrected with the help of competent software optimization. Acceleration of the smartphone is possible without the use of root rights and third-party software, if you understand the principles of the Android operating system. We will look at proven methods that will help return your device to factory friction.
It's important to understand that a comprehensive approach will give you better results than a one-time action. You need to consistently go through all the settings, paying attention to detail. Reducing the refresh rate of the screen to 60 Hz can double the battery life, but visually slow down the feeling of smoothness of the system, so for maximum speed, this parameter is better left at 120 Hz or "Auto." Let's break each step in detail.
Cleaning up memory and removing system debris
The first step to speed up is freeing up disk space, and Xiaomi’s internal memory is designed to make writing and reading speeds critically slow when it fills more than 85-90% of its capacity, because of the way flash memory works, which requires free space to distribute files efficiently.
Xiaomi’s built-in Security app has a powerful algorithm for finding temporary files, but it’s better to use specialized analysis tools to clean up deep, and don’t rely on standard cleaning, as it often leaves behind “heavy” remnants of remote applications.
- 🗑️ Use the built-in Cleanup tool in the Security app to remove cache.
- 📂 Manually delete the folders DCIM/.thumbnails, If you have a huge library, because there are miniatures.
- 📱 Turn off auto-update apps on Google Play if you have little space to prevent the system from downloading packets in the background.
- 🔄 Reboot your smartphone at least once a week to reset temporary processes.
Special attention should be paid to the Telegram messenger, which by default stores all the media files viewed in the device memory. This can take dozens of gigabytes. Go to the application settings in the Data and Memory section and set a media storage limit, for example, up to 3 days or 1 week.
⚠️ Warning: When cleaning folders through the file manager, be careful not to delete system directories whose names you do not know.
Optimization of animations and MIUI interface
The visuals of MIUI and HyperOS are often overloaded with animations that create the illusion of smoothness, but in fact only processor resources. For users who appreciate instant feedback, it is recommended to change the animation speed parameters through the developer menu.
To get into this menu, you need to go to Settings → About Phone and quickly click on the MIUI version 7 times. After the “You became a developer” label appears, you will access the advanced settings in the “Additional” or “Extended settings” section.
In the developer menu, find the Drawing section, and here we're interested in three things: "Scale of window animation," "Scale of transition animation," and "Scale of animator duration." These are set to 1x by default. Change them to 0.5x or turn them off completely (0x).
The effect of this change will be noticeable instantly: windows will open in jerks, but much faster.This creates a subjective sense of high performance of the Xiaomi smartphone. It is also worth turning off the function of “Augmented memory” if you have less than 6 GB of RAM, as using part of the storage for virtual RAM can slow down the system.
Background Process Management and Autoboot
One of the main reasons for battery drain and performance declines is the uncontrolled operation of applications in the background. MIUI shell is known for its aggressive energy saving policy, but some applications still manage to bypass restrictions.
To control it, you have to go to the battery settings and check the list of applications that consume the most power, and if you see programs that you rarely use, you have to limit their background activity, and that will free up RAM resources for your current tasks.
- 🛑 Turn off auto-start for all apps except messengers and alarm clocks.
- 🔋 In the battery settings, select Performance mode for gaming, but in normal mode use Balanced mode».
- 📵 Remove or freeze system applications you do not use (e.g. Mi Video, Mi Music, if there are alternatives).
- 🚫 Turn off personalized ads in password and security settings to reduce network load.
☑️ Background cleaning checklist
It is also recommended to disable Virtual RAM on models with 6GB of RAM or less. While marketing claims it speeds up work, in practice, using slow UFS flash memory as an adjunct to fast LPDDR often results in micro-lags of the interface.
Comparison of processor modes
Understanding how your CPU works in different scenarios helps you choose the right usage strategy. Today's Snapdragon and Dimensity chips have multiple cores at different clock speeds. The system dynamically distributes tasks, but the user can influence this process.
In Game Turbo mode, you can prioritize performance, which forces the system to keep the CPU frequencies at maximum, ignoring the heat generation within reasonable limits, and in normal mode, you better rely on automatic control.
| Parameter | The "Economies" regime | The Balanced Regime | |
|---|---|---|---|
| Clock frequency | Limited by minimums | Dynamic. | Maximum |
| Background processes | Hardly constrained. | Standard. | Permitted. |
| Screen brightness | Reduced. | Auto/User | Maximum |
| Impact on FPS | Strong decline | Stable. | Maximum FPS |
Using Performance mode in everyday tasks like social media or reading makes no sense and only warms the device, but for heavy tasks like video rendering or demanding games, it does increase FPS and frame stability.
System update and resetting
Xiaomi regularly releases security and optimization updates. Often patches fix errors that cause memory leaks, so keeping firmware up to date is a basic rule of thumb for keeping a smartphone healthy.
However, if you haven't updated in a long time and have accumulated a lot of system bugs, a simple update may not help. In such cases, an effective, albeit radical, method is a complete factory reset, which removes all user debris and returns the system to its original state.
⚠️ Warning: Before performing a Hard Reset, make sure to back up your data to the Mi Cloud or your computer. All photos, contacts and files will be permanently deleted.
The reset procedure is done through the Settings menu → About Phone → Reset. After that, the phone will work like a new one. Many users note that after resetting, even the old models start flying again, which is the most effective way if the software methods did not help.
Special features and hidden functions
Android and MIUI have features that not everyone knows about, such as turning off unused Google Play services or limiting background activity on specific services can give you speed gains on older models.
Also worth paying attention to is the Game Turbo or Accelerate, which adds even heavy work applications to this list, allowing the system to allocate more CPU resources to them and prohibit background cleaning.
- 🎮 Add frequently used apps to Game Turbo to prioritize resources.
- 🔍 Turn off Google Search on your desktop if you’re not using it, as it’s always hanging in your memory.
- 📶 Turn off Wi-Fi and Bluetooth if not in use so that the communication module does not interrupt the processor.
- 🌡️ Watch the temperature: when overheating, the system automatically resets the frequencies (trottling).
Remember that the physical wear and tear of the battery also affects the processor, so if the battery is worn out and can't produce the voltage it needs, the system artificially slows down to avoid a sudden shutdown, in which case software optimization will only have a temporary effect.
