Xiaomi smartphone slows down: what to do and how to speed up

The situation when the once-quick Xiaomi or Redmi suddenly begins to react to latency touches is familiar to many owners. MIUI or HyperOS interface, despite its functionality, over time becomes overgrown with cache, background processes and system debris, which inevitably affects performance. This is not always a sign of hardware failure, often the problem lies in software conflicts or overflow of storage.

Before you bring your gadget to a service center or think about buying a new model, it is worth conducting a comprehensive diagnosis and optimization. There are many hidden settings and proven methods that allow you to return to the previous speed even budget devices. In this article, we will discuss step-by-step actions that will help eliminate lags and friezes without losing personal data.

The first thing to do is to understand the nature of the brakes: whether they are permanent or only in heavy applications. If the interface is even in the settings menu, then the problem is likely to be overcrowded memory or system processes failure. If the delays are only noticeable in games, the emphasis should be on settings for graphics and freeing RAM.

Analysis of memory and storage occupancy

The most common reason Xiaomi is slowing down is critical internal memory filling: When less than 10% of the total is free, the system cannot use buffering effectively, leading to a sharp drop in performance. You can check the current state in the Settings β†’ Memory menu, where detailed usage statistics will be displayed.

Particular attention should be paid to the folder DCIM/Camera And the cache of messengers like Telegram or WhatsApp, which can take up tens of gigabytes, and the built-in cleaning tool often doesn't see these files, so it's recommended that you manually delete old videos or transfer them to your computer. It is also worth checking the β€œDownloads” section where installation files could have accumulated. APK and unnecessary documents.

⚠️ Warning: Do not fill the device's internal memory to the end. For stable operation, the file system always needs free space for temporary files and caching write operations.

For quick cleaning, you can use the standard Security app, which has a built-in Cleanup tool. However, for deep analysis, it is better to use third-party utilities or file managers, such as Files by Google or Total Commander, which allow you to see the real folder structure and remove duplicates.

Optimization of MIUI and HyperOS interface

Xiaomi’s shells are famous for their visual richness, but the abundance of animations and live wallpaper can overload the processor, especially on models of the past. To speed up the response of the system, you can reduce the scale of animation in the developer menu, which will create the illusion of faster work, as transitions between screens become instantaneous.

To access hidden settings, you need to activate the developer mode by quickly clicking seven times on the build number in the About Phone section. After that, in the extended menu, find the "Scale of Windows Animation", "Scale of Transition Animation" and "Duration of Animation" items. Set 0.5x or completely disable them.

Another resource-intensive element is the Memory Extension function, which disables part of the internal storage for RAM. paradoxically, on smartphones with fast flash memory UFS 2.1 or 2.2, this feature can even slow down due to a lower read/write speed compared to real RAM. Try to disable this option in the settings to see if the system becomes more responsive.

Why does animation affect productivity?
Every movement of the interface requires rendering by a graphics accelerator. On older models, the GPU may not be able to handle frame rates of 60 or 120 Hz with open heavy applications, creating a task queue and causing micro-freezes.

Managing Autoboot and Background Processes

Many apps in the Android ecosystem tend to run with the system and stay active in the background for notifications or content updates. On Xiaomi smartphones, this process is controlled by MIUI Optimizer, but often users allow unnecessary programs to be constantly active, which leads to the fact that RAM is occupied with unnecessary tasks.

Follow the Settings β†’ Apps β†’ Autostart and carefully study the list. Leave only instant messengers and alarms on, which are critical to instant work. Social networks, games and stores can be safely turned off - they will start when you want them to.

πŸ’‘

Use App Sleep mode in battery settings for programs you rarely use, which will prevent them from doing any background activity until the next manual start.

App permissions are also worth checking. Often programs request access to geolocation or microphone for background work, which consumes the CPU resources. Under Settings β†’ Security & Security β†’ Permissions, you can restrict the rights for suspicious or rarely used utilities.

⚠️ Warning: Do not disable system services with unknown names or logos Xiaomi/Android in autoboot, as this can disrupt the stability of the phone and lead to cyclical reboots.

Cleaning the cache and removing system debris

Accumulating temporary files is a natural process, but it can become a problem over time. Cache speeds up the loading of frequently visited pages and features used, but bloating it to gigabyte sizes causes the opposite effect. Standard cleaning through the Security menu is the first step, but not always sufficient.

To clean it up, you can use Recovery mode, turn off your smartphone and press the Volume Up + Power button combination (on some models Volume Down + Power). In the menu that appears, select Wipe Cache (don't confuse it with Wipe Data!), which will delete temporary system files without affecting your personal data.

If the smartphone is slowing down after a firmware update, it makes sense to clear the cache of a particular problem application or the entire system through the developer settings. In the Developer section, find the "bootloader" or "Cache Reset" option if it is available in your version of the software.

  • 🧹 Regularly clean the browser cache, which often grows to incredible sizes.
  • πŸ“± Remove Remnants of Remote Applications Using File Manager.
  • βš™οΈ Drop the cache DNS In the settings of the network, if there are problems with the Internet.

Deep cache clearing via Recovery is safe for user data, but requires turning off the phone and logging into a dedicated download menu.

Specific problems of advertising software and viruses

One of the hidden reasons why Redmi or Poco might slow down is the aggressive MSA (MIUI System Ads) advertising integration. Ads modules consume Internet traffic and processor resources to download and display banners in system applications, a feature that makes life much easier for the device.

To remove ads, go to Settings β†’ Passwords and Security β†’ Access to personal data. Find msa in the list and turn off the switch. The system will repeatedly offer to wait 10 seconds before turning off β€” agree and click β€œCancel.” Also, turn off receiving recommendations in the settings of each system application (themes, music, video, Explorer).

In rare cases, the cause of lags are malware, miners or Trojans that disguise themselves as harmless utilities. If the phone warms and slows even in simple, check the list of installed applications for suspicious names or programs with administrator rights.

Radical measures: Resetting and reflashing

If software optimization fails, the last effective method is a complete factory reset, which will remove all data, applications and settings, returning the smartphone to the β€œout of the box” state.

You can reset via the Settings menu β†’ About Phone β†’ Settings reset β†’ Erase all data. Once rebooted, the system will be clean, without accumulated debris and conflicts. The first 30-60 minutes after turning on the phone can work slowly, as file indexing and application background optimization are normal.

What is Clean Install?
This is a reset of firmware through a computer with full memory partition cleaning, which is more difficult than a regular reset, but ensures that any system errors and remnants of old versions of software are removed.

In some cases, you need to flash the device through the Mi Flash Tool, which is true if the phone is locked on a wrong global firmware or Chinese version with unstable translation, but for the average user, a standard reset is enough that solves 90% of performance problems.

⚠️ Before performing a full reset, make sure that the battery level is at least 50%, and remember the passwords from Mi-account and Google, otherwise it will be impossible to unlock the device.

Hardware limitations and wear

The physical wear of components cannot be ruled out, as flash memory has a limited life of overwrite cycles, and over time its reading speed can fall, which manifests itself in the long opening of applications, and the cause may be the degradation of the battery, which is not able to produce the peak currents required by the processor to operate at high frequencies.

Overheating is another factor that causes the system to artificially lower the CPU frequencies (trottling). If the smartphone brakes during games or video shooting, check if the speaker's holes are filled with dust, and if you use a case that prevents heat sinking.

If none of the software methods worked, and the reset only had a short-term effect, the problem may be the hardware, and you should contact an authorized service center to diagnose the motherboard and replace the thermal interface.

Why does the phone start to slow down after an Android update?
After a major system update (for example, the transition from Android 12 to 13), the first days may experience a decrease in performance, this is due to background optimization of databases and re-indexing files for the new version of the kernel, usually after 2-3 days of active operation, the situation stabilizes.
Does Power Saving Mode Help Speed Up Your Phone?
No, energy saving mode, on the contrary, limits the performance of the processor and background activity to extend the running time, and for games and heavy tasks, it should be turned off, switching to Balanced or Performance mode.
Do I need to install third-party antiviruses on Xiaomi?
In most cases, the built-in scanner in the Security app is sufficient. Third-party antiviruses often consume a lot of resources themselves and can conflict with system optimization of MIUI, causing additional lags.
How often should I reboot my smartphone?
Modern operating systems do not require daily restarts, but simply reboot the device once a week or when there are obvious signs of instability to clear the memory of accumulated errors.
