Modern Xiaomi smartphones are famous for their excellent value for money, but over time, even powerful flagships can start to work slower. Users often face delays when switching apps, slowing down the MIUI or HyperOS interface and quickly discharging the battery. This does not always mean that the device has worn out physically; often the problem lies in software accumulation and improper configuration of the system.
Owners of devices with a shell MIUI or new HyperOS should understand that aggressive optimization of power consumption sometimes works against the user, forcibly closing the desired processes. To return the former abruptness to your device, you need to conduct a comprehensive “digital cleaning” and change a number of hidden settings. In this article, we will discuss proven methods that will help significantly improve the performance of your device.
Before you start taking drastic measures like factory resets, you should try less invasive optimizations, which don't require deep technical knowledge and are safe for your personal data, and if you set up the system properly, you can extend the comfortable life of your smartphone by several years without having to buy a new model.
Analysis and release of RAM
One of the main reasons for the slowdown is overflow of RAM (RAM). When free resources become critically scarce, the system has to constantly unload background processes, which leads to delays in launching applications. Owners of models with 4 or 6 GB of memory are especially acutely aware of the lack of resources when working with heavy programs.
To start, you need to remove unused applications and clear the cache of system services. Xiaomi’s built-in Security app provides basic tools, but for deep cleaning, it is better to use specialized utilities or manual cleaning through settings. Freeing even 500 MB of memory can significantly affect the smoothness of animations.
Special attention should be paid to messengers like Telegram and WhatsApp, which tend to accumulate gigabytes of temporary files. Regular cleaning of media files inside these applications is a mandatory procedure to maintain high speed. Remember that a filled internal drive also slows down the recording and reading of data.
- 🚀 Use the built-in accelerator in the notification curtain for quick resetting of background tasks.
- 🗑️ Remove the heavy game cache through the memory management menu in the settings.
- 📱 Turn off automatic app updates in the Play Market if the memory is full.
- 🔄 Reboot your smartphone at least once a week to reset system processes.
⚠️ Warning: Do not install questionable "cleaner" applications from unverified sources. They often consume resources and display intrusive advertising, only making things worse.
There is a myth that constantly cleaning up memory is bad for the device, but in the Android mobile OS, periodic resetting of accumulated errors is necessary. However, you should avoid fanaticism: if you just started a game, you do not need to immediately kill the process to free megabytes.
Customization of animations and MIUI interface
The visuals of Xiaomi’s shell are beautiful, but the plentiful animations can create the illusion of a device running slowly, especially on models from the past. Reducing the length of transitions between screens makes the interface more responsive and “live.” It’s a simple trick that instantly changes the perception of smartphone speed.
To access these settings, you need to activate the developer mode. Search the About Phone menu and click seven times on either MIUI Version or OS Version. Then a new section will appear in the advanced settings where you can find animation zoom options. Changing the value from 1x to 0.5x or completely disabling speeds up the response.
And then we need to rethink the use of live wallpaper and heavy widgets on the home screen, which consume GPU and battery resources even in standby mode, and replacing the dynamic screensaver with a static image is one of the easiest ways to reduce the load on the system.
And the theme is also the theme. Some third-party themes downloaded from Mi Themes may be poorly optimized and heavy graphics. If you notice lags after you change the theme, go back to standard design. The standard Classic or Default theme is always the most stable.
Optimization of energy and battery
Processor performance is directly dependent on battery status and energy saving settings. When the charge drops below 20%, the system automatically limits the clock speed of the processor to extend the running time. In addition, the "Energy Saving" mode can block background synchronization and GPS operation, which affects the functionality of navigators and messengers.
In the battery menu, you can customize the behavior for each application separately. For programs that need to run constantly (such as mail or trackers), you should set a background activity restriction in the “No Limits” mode, which will prevent the application from being forced to close by the system, but can slightly increase the charge consumption.
The use of the original charger and cables also plays a role in the long run: Quick Charge or SuperCharge fast charging must work properly so that the power controller does not experience stress. Overheating during charging is the main enemy of battery chemistry, leading to degradation and voltage drop under load.
| Mode of work | Impact on CPUs | Recommended use |
|---|---|---|
| Productive | Maximum frequency | Games, hard challenges |
| Balanced | Dynamic change | Daily use |
| Saving energy | Strong constraint | Critical battery charge |
| Ultra-savings | Minimum set of functions | Survival regime |
It's also worth checking the battery consumption statistics in the settings. If you see an application that you're not actively using but it's consuming a significant percentage of charge, it's a signal to action. It might be that the process is stalled or that the application has errors that cause the processor to cycle.
Removal of system debris and advertising
MIUI is known for its built-in advertising that not only annoys but consumes Internet traffic and CPU resources to load ad units. Disabling personalized advertising is an important step not only for comfort, but also to increase overall interface responsiveness, through Mi Account service settings.
In addition to advertising, the system is littered with error logs and temporary update files. Built-in cleaning utility copes with basic tasks, but sometimes manual intervention is required. For example, the Download folder is often filled with APK installation files, which are no longer needed after installing programs.
It is also recommended to disable automatic recommendations in system applications. In Explorer, Music and Topics, there are Receive recommendations switches that should be put into an inactive state, which will remove unnecessary requests to servers and speed up the launch of these applications.
- 🔒 Shut down msa service (MIUI System Ads in Authorization and Advertising Settings.
- 📂 Check the Downloads folder regularly for old installers.
- 🚫 Stop apps from showing notifications over other windows in special features.
- 🧹 Use the Cleanup feature in the Security app once a week.
⚠️ Note: Be careful when deleting files in Android system folders. only delete the one you are sure of, so as not to disrupt the system.
Disabling unnecessary system services, such as Google or Xiaomi services you don’t need (such as Mi Video if you don’t use them), also helps, but it’s important not to overdo it and disable critical components that run the app store or sync contacts.
☑️ Checklist of fast optimization
System update and resetting
Often performance issues are related to software bugs in the current firmware version. Xiaomi developers regularly release updates that contain security patches and code optimization. Checking for updates through Settings → About the phone should become a regular habit.
If the phone started to slow down after the last update, there may be a conflict of files of the old and new system, in such cases, it helps to clear the update cache or completely reset to factory settings. Before reset, be sure to back up your data in the cloud or on your computer.
The Wipe Data procedure puts the phone back into a boxy state, a radical but often the only way to get rid of the deep-seated software bugs that have accumulated over the years. After a reset, you don't have to install hundreds of apps at once, you'd better do it gradually, tracking each one's impact on speed.
Settings → About Phone → MIUI Version (7 times) → Advanced Settings → ResettingIt is important to note that after a major system update (for example, the transition from Android 12 to 13), the phone can run slowly for the first 1-2 days, during which time there is a background indexing of files and optimization of applications for the new version of the random.
Use of Extended Functions for Developers
For advanced users, the developer menu provides access to fine-tuning the processor and memory, where you can limit the number of background processes, which will free up RAM for active tasks, but use these functions with an understanding of the consequences.
One useful feature is to disable hardware acceleration for interface rendering (GPU) if graphic artifacts are observed, although this is rarely required on modern devices.More relevant is Minimum Width Scale (DPI) management, but changing this parameter can make the interface unreadable.
Also on this menu is the Wi-Fi Aggregation setting, which theoretically speeds up the internet using both Wi-Fi and mobile network, which can lead to increased traffic and battery consumption, so only switch on when the connection is unstable.
⚠️ Warning: Changing the settings in the Developer Menu can cause system instability. Write down your changes to get things back to normal if necessary.
And don't forget the "Don't keep activities" feature, which is sometimes advised to speed up, which causes the system to kill the application as soon as you leave the screen, which gives a false sense of speed, but causes the processor to constantly restart applications, which ultimately consumes more energy and time.
Hardware factors and device care
You can't ignore the physical condition of the smartphone, too. Overheating is one of the main enemies of performance. When the CPU temperature reaches critical values, trottling kicks in and the phone starts to brake very badly. Using cases that disrupt the heat sink in hot weather can exacerbate the problem.
The wear and tear of the memory storage is another factor: Flash memory has a limit to overwriting cycles. If the phone is 4-5 years old and has been in active use, the read/write speed may have dropped physically, in which case software optimization will only have a temporary effect, and the only solution is to replace the device.
Regularly restarting at least once a week helps to reset errors in communication modules and memory controllers, a simple procedure that is often forgotten when you keep your phone on for months, and it is also worth keeping an eye on the free space: a drive that is more than 90% full is much slower.
- 🌡️ Remove a thick case while playing or charging for better cooling.
- 💾 Keep it at a minimum. 10-15% internal memory for proper operation of the system.
- 🔋 Avoid using your phone while charging fast so as not to cause overheating.
- 📱 Use original charging accessories to avoid voltage surges.
In conclusion, a comprehensive approach to serving your Xiaomi will allow you to enjoy the fast operation of the device for many years. The combination of software cleaning, the right settings and gentle physical handling works wonders even with budget models.
