The situation when the once-quick Xiaomi smartphone suddenly starts to hang, open applications for a long time or react to touches with a delay is familiar to many owners. This is not always a sign of hardware failure or failure of the gadget. Most often the cause lies in software conflicts, cache overflow or the peculiarities of the MIUI shell and the new HyperOS.
Before you bring your device to the service center, you should do a number of diagnostic procedures yourself. Optimizing the system can restore the former agility even to models of the past. In this article, we will discuss effective methods that will help eliminate the lags and improve the performance of your device.
Remember that ignoring the first signs of slowdown can lead to more serious software problems. A critical factor is often filling the system partition by more than 90%, which causes file indexing to fail.
Analysis of the causes of slowing down of the system
The first step in solving the problem is to understand what exactly is causing the strain on the processor and RAM. The Android operating system that underlies the shell is prone to accumulating temporary files. Over time, this turns into “digital garbage” that slows down the reading of data from the drive.
Often the culprits are background processes, apps may not shut down completely, but they may continue to consume resources even when you don't use them, especially social networks and instant messengers that are constantly updating content.
- 📉 Overflowing internal memory is the main enemy of data writing speed.
- 📱 Unoptimized or “heavy” versions of apps (such as Facebook or Instagram).
- 🌡️ Processor overheating causing trottling (forced frequency reduction).
If the battery is worn out and cannot produce the required current under load, the system can artificially limit performance to prevent sudden shutdown.
Cleaning up memory and removing system debris
The easiest and most efficient way to get back to speed is to free up space. The built-in Cleanup tool in the Security app is the first thing to start with. It deletes the app cache, the remnants of deleted programs and temporary files.
But automatic cleaning doesn't always find it all redundant: manually check the Download and DCIM folder. Often it stores old APK videos, screenshots, and installation files that you don't need anymore. Deleting even 1-2 GB of data can significantly improve interface response.
☑️ Checklist for quick cleaning
Pay special attention to messengers. Telegram and WhatsApp tend to grow to giant sizes, preserving all media history. Go to the storage settings inside these applications and clear the cache without deleting important correspondence.
⚠️ Note: Do not delete files from Android system folders and MIUI, If you're not sure what they're doing, it could cause the system to malfunction or the application data to be lost.
Optimization of the interface and animations
The visual smoothness of MIUI and HyperOS is achieved through animations, so if the phone is slowing down, turning off or accelerating these effects will create the illusion of faster work, and this will require access to the developer's advanced settings.
To activate the developer menu, go to Settings → About Phone and quickly click 7 times on the MIUI Version (or OS Version). After the notification “You became a developer” appears, open Additional Settings → For developers.
Find the section related to drawing and change the following parameters:
- 🎨 Windows animation - install 0.5x or "No animation».
- 🎞️ Transition animation - install 0.5x.
- ⏱️ Duration of animation - set 0.5x.
The changes take effect instantly. The interface will become more twitchy, but the response to commands will seem instant, and this is especially true for low-end models with entry-level processors, where every bit of the processor counts.
💡
If the interface twitches too much after changing the animation settings, return the 0.5x value – this is the optimal balance between speed and visual comfort.
Managing Autoboot and Background Processes
Many applications are prescribed to boot, starting immediately after the phone is turned on, which consumes RAM and charges the processor with tasks that you don't need right now, and controlling this process gives you a tangible increase in performance.
In the Developer menu, look for the Background Process Limit, the default is Standard Limit, you can limit the number of processes to 2-3 or choose No Background Processes, but beware: this can disrupt the notifications from messengers.
A softer method is manual control of autostart:
- Open the Security app.
- Go to the Permissions section → Auto-start.
- Disable all applications that do not need to work constantly (navigators, stores, games).
Leave auto-run only for messengers and alarms on, which will free up the system resources for active user tasks.
Comparison of acceleration methods
Not all methods are equally effective for different models. For older devices, cleaning memory is critical, and for new ones, adjusting animations. Below is a table that helps you choose a strategy based on your symptoms.
| Symptoms. | Probable cause | Method of decision | Efficiency |
|---|---|---|---|
| Long-term applications open | Lack of RAM | Cleaning up memory and cache | Tall. |
| Lacking menus and desktop | Heavy shell graphics | Shutdown of animations | Medium |
| The phone is warming and slowing down. | processor trottling | Resetting or replacing the battery | Tall. |
| The Internet disappears in the background | Aggressive energy conservation | Auto-start setup | Medium |
Use this table as a diagnostic tool, and if your case doesn't fit into any category, it may be deeper, in hardware or in system file corruption.
💡
A comprehensive approach combining memory cleaning and visual effects shutdowns delivers the best results on the Redmi and Poco budget smartphones.
Advanced settings and reset
If the software methods didn't work, you can try more radical measures, resetting the settings to factory (Wipe Data) puts the phone back out of the box, and this is guaranteed to remove all the software errors accumulated over the years of use.
Before the procedure, be sure to back up your data in the Mi Cloud or on your computer. Reset will delete all photos, contacts and applications. After the reset, do not restore the backup of the applications immediately - better install them again to avoid returning junk files.
How to make a complete reset (Hard Reset)
There is also a myth of “overclocking” through third-party apps, which experts do not recommend using booster programs that promise to speed up the phone in one click, often they themselves are a source of advertising and background load, making things worse.
⚠️ Note: Using third-party programs to deep clean the registry or system files on Android can lead to a “brick” of the device. MIUI.
