Xiaomi smartphones are famous for their excellent price-performance ratio, but over time, even the most powerful flagships can start to work slower. It is a natural process of accumulation of system debris, data fragmentation and weighting shells such as MIUI or HyperOS. Users often notice delays in the interface, long opening of applications or sudden reboots, which significantly reduces the comfort of using the device.
There are many reasons why Redmi or Poco start to slow down: crowded cache, background processes, an outdated version of firmware or even wear of internal memory. In this article, we will discuss effective ways to help return the ache to your gadget without using third-party software, you will learn how to properly configure the hidden developer settings and which shell functions are best to turn off for maximum efficiency.
Before we go to radical measures like factory resets, it’s worth trying software optimization methods. Android has powerful built-in resource management tools that are often hidden from the eyes of the average user. Proper use of these tools allows you to extend the life of the device for several years, keeping its responsiveness at a high level.
Cleaning up memory and removing system debris
The first and most obvious step in speeding up a smartphone is to free up internal storage. When the free disk space runs out, the speed of writing and reading data drops, which leads to lags. The system uses some of the memory as a buffer for temporary files, and if this buffer is full, the RAM begins to work with overload, causing slowdowns.
The MIUI shell has a built-in Security app that automatically scans the device for junk files. However, it's worth doing a deep manual cleaning by going to the storage settings. Pay special attention to messenger folders, as they often grow to giant sizes, taking up gigabytes of space with a cache of images and videos.
💡
Use the Cleanup feature in the Security app once a week to delete temporary system process files and residual files from remote applications.
It's also important to check the installed list, and often users forget about programs that have been off for months, but that continue to hang in the background and consume CPU resources, and removing unnecessary software is an easy way to reduce the CPU load.
- 🗑️ Remove rarely used apps through the settings menu.
- 📂 Move photos and videos to a memory card or cloud.
- 🧹 Clean the browser and social media cache manually.
- 📵 Disable or remove system applications if you have root rights.
Remember that overcrowded memory affects not only the speed of the drive, but also the life of the drive. Constant overwriting of data in the face of space shortage accelerates the wear of memory cells, which in the long run can lead to hardware problems.
Optimizing settings for developers
One of the most effective ways to visually speed up the interface is to change the animation settings. The developer menu has settings that control the speed of transitions between windows and the scalability of elements. By default, these values are set to 1x, but reducing them to 0.5x creates the illusion of faster system operation.
To access this menu, you need to click on the build number several times in the About Phone section. Once the developer mode is activated, go to the advanced settings and find the "Windows Animation Scale", "Scale of Transition Animation" and "Duration of Animation" paragraphs. Changing these parameters does not increase the actual performance of the processor, but makes the system response instantaneous.
⚠️ Note: Do not change the parameters associated with the "Background processes" if you do not understand their purpose. Forced restriction of background processes can lead to incorrect operation of messengers and failures in data synchronization.
What is the limitation of background processes?
Another important parameter is to enable hardware rendering acceleration. GPU. This feature forces the GPU to take over some of the drawing tasks 2D-And on today's devices, this can give you a real boost in smoothness when you scroll through lists and menus.
| Parameter | Default value | Recommended value | The effect |
|---|---|---|---|
| Window animation | 1x | 0.5x | Acceleration of opening/closing |
| Animation of transitions | 1x | 0.5x | Quick screen switching |
| Duration of animation | 1x | 0.5x | Reduction of waiting time |
| Background processes | No restrictions. | No more than 4. | Saving RAM (cautiously) |
These settings are especially relevant for budget models like the Redmi Note series or the Poco M, where iron resources are limited. For flagship models, it’s more a matter of preference in the response speed of the interface.
Managing Autoboot and Background Processes
Many applications tend to run with the operating system and stay active in the background, which leads to constant consumption of RAM and CPU cycles, which directly affects performance. In the MIUI shell, there is a powerful tool for monitoring autoboot that needs to be configured.
Go to settings, find the Apps section, and select AutoRun. Here you will see a list of all the programs that start with your phone. Leave only those that you really need right after you turn on (such as messengers to receive notifications), and turn off the rest safely.
Also, check the power saving settings for each application. The system can aggressively kill processes, but sometimes it allows heavy applications to run without restrictions. Go to Battery and Performance and set No Limits mode for mission-critical tasks only, and for the rest, select Background Savings.
- 🚫 Turn off autoplay for games and heavy editors.
- 🔋 Set up energy saving profiles for each application.
- 📉 Close the background apps through the recent task menu.
- 🛑 Limit background data transfers for rarely used programs.
Regular background checks help keep the system on track, and if you notice that your phone is heating up in your pocket, it's likely that some app is actively operating in the background, consuming resources.
☑️ Background activity check
Update the system and remove beta versions
Relevance of software is a key factor in stability. Xiaomi developers regularly release updates that contain not only new features, but also bug fixes, as well as code optimization. If your device has an old version of MIUI installed, switching to a new one can significantly improve performance.
However, there is also the opposite situation: install beta versions of firmware. Test builds often contain bugs and unoptimized code, which leads to lags and quick battery discharge. If you use a version marked "Beta" or "Dev", it is recommended to return to a stable update branch.
⚠️ Warning: Before updating your firmware, make sure to back up your data. The flashing process can lead to loss of information, especially when switching between Android versions.
You can check for updates in the About Phone section, if you don't get an automatic update, you can use manual installation through the firmware file selection menu, and it's important to download files only from the official website or trusted sources.
Sometimes, after a major system update (for example, the transition from Android 12 to 13), the phone may slow down in the early days. This is normal: the system indexes files and optimizes applications in the background. Usually after 2-3 days of operation, the situation stabilizes.
Resetting settings as a radical method
If software methods fail, the last effective way is to completely reset to factory settings, which removes all user data, settings and applications, returning the phone to the “out of the box” state, often because of the accumulated configuration errors over the years of use cause unstable work.
Before resetting, make sure all important data is saved, photos, contacts and documents are better uploaded to an external medium or to the Google Drive cloud storage, and once reset, the phone will work as quickly as possible, since all software “junk” will disappear.
To perform the reset, go to Settings → About Phone → Settings Reset. Select “Erase All Data.” The process will take some time, after which the device will restart and prompt you to go through the initial setup.
💡
A complete reset is the only guarantee of removing hidden system errors that cannot be corrected by a conventional cache cleanup.
You don't need to install hundreds of apps after you reset, try using a clean phone for a couple of days, if it's fast, it's a software environment, and install the apps gradually, tracking which one comes back up.
Effects of temperature and operating mode
The performance of a smartphone depends on its temperature, and when it's warmed above a certain threshold, it triggers a trottling mechanism that artificially lowers the CPU frequencies to prevent overheating and damage to components, so if the phone is hot, it will run slowly.
Avoid using your phone while charging, especially if you play heavy games or shoot high-resolution videos. Also, don't leave your device in direct sunlight or on your car panel in the summer. Optimal temperature ensures that the SoC (system on a chip) works smoothly.
In the battery settings, you can select the performance mode. For everyday tasks, Balance mode is optimal. Performance mode should only be turned on for a short time when maximum power is needed, since it significantly increases power consumption and heating.
- 🌡️ Watch the temperature of the device body.
- 🔋 Remove the cover if it interferes with cooling.
- 🎮 Do not play during fast charging.
- ⚖️ Use Balance Mode for Daily Use.
Understanding the thermal conditions of your Xiaomi will help to avoid situations where the phone suddenly begins to “dull” at the most inopportune moment.
