Modern Xiaomi, Redmi and Poco smartphones are known for their price-performance ratio, but even powerful devices can become unstable over time. Users often face a situation where the interface reacts with a delay, applications close on their own, and the phone suddenly freezes. This is annoying, but in most cases the problem is solved without going to the service center.
The causes of the operating system's instability may be software or hardware, most often the culprit is a crowded internal memory, background processes, or update conflict, and understanding the nature of the problem is the first step to restoring your gadget's performance.
In this article, we will take a comprehensive approach to diagnosing and eliminating bugs. We will look at both simple cleaning methods and more complex actions, such as resetting. If your Xiaomi has started to behave strangely, do not panic - follow the instructions below.
Primary diagnosis: analysis of symptoms
Before we start taking drastic measures, we need to understand exactly when a failure occurs. Symptoms can range from periodic twitching of the screen to full locking of the device. If the phone only glitches in heavy games, the problem can be in the overheating of the processor.
Notice the frequency of errors: random hangings once a week and constant lags every five minutes require very different approaches to solving, in the first case, you just need to optimize the system, in the second - look for deep conflicts of software.
- 📱 The screen stops responding to touch for a few seconds.
- 🔄 Applications close with an error or “fly out” to the desktop.
- 🔋 The device quickly discharges and warms up in downtime.
- 📶 Wi-Fi or network disappears for no apparent reason.
If you notice that the phone freezes immediately after installing a particular application, it is likely that it conflicts, in which case, removing the problematic software often solves the issue instantly.
⚠️ Note: If the phone is buggy immediately after purchase, do not try to fix it yourself - it may be a factory defect that requires replacement under warranty.
It's also worth checking if the case is overheating.The high temperature causes the Xiaomi processor to reset frequencies, leading to a severe performance drop and lags.
Cleaning up the system's memory and cache
The most common reason Redmi or Poco is slowing down is a lack of storage space, and when internal memory is more than 85-90% full, the system lacks resources for temporary files and swap files, causing critical delays.
Start by removing unnecessary files: photos, videos, and duplicate applications. The built-in Cleanup tool in the MIUI or HyperOS shell helps to quickly free up space, but don't rely on it alone. Manually checking folders in the file manager often gives the best result.
Pay special attention to the cache of applications. Over time, messengers and browsers accumulate gigabytes of temporary data, which slows down the work, Clearing the cache will not delete your correspondence, but will speed up the launch of programs.
Use the built-in Security app. Go to Cleanup and run the scan, and the system will prompt you to remove the debris that is taking up space.
Optimization of MIUI and HyperOS settings
Xiaomi shells are rich in features, but some of them can waste resources. Animations, live wallpaper and desktop widgets put a strain on the GPU. If the phone is getting glitzy, try simplifying the visual interface.
Go to the settings and find Advanced Settings → Special Features → Visual Effects, where you can turn off animations or reduce their duration, not only will the system respond faster, but also visually make the smartphone work faster.
Hidden settings for developers
To access hidden features, go to About Phone and click on Version 7 times. MIUI». In the “For Developers” menu, find the “Scale of Animation” item and set the value 0.5x Or turn them off completely.> Also worth checking is the boot list. Many applications are prescribed to start without the user's knowledge. Turn off auto-run for those programs you don't use immediately after you turn on the phone. 🚫 Turn off the “Always on display” if the battery is weak. 📉 Reduce screen resolution in display settings to boost FPS. 🔇 Remove the widgets from the home screen. Remember, live wallpaper is one of the main users of resources. GPU. Replacing them with a static image often works wonders with older smartphone models. Update or rollback system The issue of software updates is dual. On the one hand, new firmware versions contain security bug fixes and bug fixes. On older devices, installing a heavy new OS can cause brakes. → If a new version comes out, try updating. However, if the phone starts to glittle right after the update, you might want to consider rolling back on the previous version or patching (OTA) Safe, saves data May not solve deep errors Recommended Manual Firmware Complete cleaning of the system Difficult, risk of data loss For experienced users Beta New features before all Instability, bugs Not recommended If you use beta firmware, transition to a stable branch (Stable) ROM) often eliminates most glitches. Beta testing is designed to find errors, not to work comfortably on a daily basis. ⚠️ Warning: Before any update or flashing, be sure to back up important data to the cloud or your computer. 💡System stability is more important than having the latest features. If the current version works well, don't rush to upgrade. Sometimes it helps to completely reset after an update, because old system files can conflict with new ones. This takes time, but gives a clean system. Removing viruses and malware, although Android and MIUI have built-in protection, the risk of infection still exists, especially if you install applications from third-party sources (APK-Miner viruses or ad modules can quietly load the processor, causing strong lags. The built-in scanner in the Security app uses Avast databases or AVL It's good at dealing with basic threats. You can use Dr.Web Light or Kaspersky to do deep vetting. 📊 Where do you most often download apps?Google Play StoreThird-party sites and forumsAPK-Pay attention to the behavior of the system: if an ad pops up on the desktop or menu, it means that a malicious application is lurking in the system. Often it is disguised as a system process or has a transparent icon. Go to your app settings and look carefully at the list, look for programs without a name or with suspicious access rights, and removing such software will return the phone to normal speed. 🛡️ Enable “Fraud Protection” in your security settings. 🚫 Prohibit the installation of applications from unknown sources. 🔍 Check the access rights of the installed games and utilities. If you can't remove the virus in the usual way, you may need to completely reset to the factory settings, this is guaranteed to remove any software other than the system. If nothing works, you have a heavy artillery, a complete reset, and it will bring your phone back out of the box by removing all your data, accounts and apps, and it's the most effective way to combat software glitches. Before the procedure, make sure that the phone is at least 60 percent charged. → The phone. → Resetting settings → Erase all the data. It takes 5 to 15 minutes. Recovery menu: 1. Turn off the phone. 2. Press Volume Up. + Power. 3. Select Wipe Data → Wipe All Data. 4. Confirm and wait until the end. Once reset, the phone will run fast like a new one, however, if the problem was hardware (e.g., flash memory degradation), the glitches may return even after a clean system installation. ⚠️ Warning: Do not interrupt the reset process or force the phone to turn off, otherwise the device may turn into a brick and require recovery through the computer. Restore from a backup is best done selectively, without installing all applications at once. This will help identify the culprit behind the slowdown if the problem recurs. Hardware problems and component wear Don't forget that a smartphone is a physical device. Over time, components wear out. A bloated battery can put pressure on the board, causing contact failure. Overheating of the processor due to dried thermopaste also leads to trottling and lagams. If the phone falls or is exposed to moisture, the hardware is more likely to be affected, and in such cases, the software methods are powerless and a diagnosis is required at a service center. 💥 Battery bloating (phone lying unevenly on the table). 🌡️ Strong heating of the lower part of the body for simple tasks. 📡 Interference with the speaker or microphone, it also matters the age of the device. 4-5 In the years to come, modern versions of apps and websites may be too heavy for its processor, in which case only the “light” version of the OS or a change of device will help. There are applications for overclocking the processor, but on Android they often backfire, causing instability and rapid battery wear. Don't use them. Frequently asked questions (FAQ) Why Xiaomi phone is glitching after the update? After the upgrade, the system performs background optimization of applications, which can take up to several hours. Also, the new version can be heavier for the old hardware. If the lags do not pass through the day, try resetting. How to clear the cache on Xiaomi without losing data? Use the built-in Security application → Cleanup. This will delete temporary files, but save your photos, contacts and correspondence in messengers. Can the virus cause freezes? Yes, miners and ad viruses are heavily loading the processor. Check the phone with antivirus and remove the newly installed applications from the "Clean" if the device is not updated from the screen, it needs to fix the physical source. It doesn’t speed up the processor, but turning off animations in the developer menu makes the interface visually more responsive, hiding rendering delays.
