The situation when the once-fast Xiaomi suddenly starts to work slowly, is familiar to many users: the screen reacts with a delay, applications open longer than usual, and interface animations turn into a ragged slideshow. This is not necessarily a sign of hardware breakdown, most often the problem lies in software conflicts or memory overflow.
The Android operating system that runs the MIUI or HyperOS shell is becoming increasingly overgrown with temporary files and cache. Digital garbage is a natural process, but it requires periodic intervention. If you notice your smartphone is slowing down, don't rush it to the service center.
In most cases, you can restore normal speed by yourself by following a series of simple optimization steps, and we will discuss effective methods to help bring the device to life without losing personal data.
Analysis of memory and storage occupancy
The first thing to look out for when the phone starts to slow down is the free space in the internal memory. When more than 85% of the storage capacity is full, the Android system can't effectively manage paging files, which leads to severe delays. Delete unnecessary videos, heavy files from messengers or transfer them to a microSD card or to the cloud.
Special attention should be paid to the cache of applications. Social networks and browsers can take up gigabytes of temporary data. Go to Settings → Apps → All applications, select the most voracious programs and click the “Clean” button. This is secure and will not delete your logins or correspondence, but will free up space for the system to work.
- 🗑️ Remove rarely used games that take up a lot of gigabytes.
- 📸 Check the Recycle Bin folder in the gallery, often deleted photos are stored there.
- 💬 Clear the cache in Telegram and WhatsApp through the settings of the application itself.
There is a common misconception that cleaning up memory always solves the problem, but if the situation has not changed since the release of 10-15 GB, then it is not the volume, but the fragmentation of data or file system errors, in which case it helps to restart the device, which forcibly closes the suspended processes.
Optimization of MIUI and HyperOS interface
Xiaomi shells are known for their functionality, but they also consume significant processor resources. If the phone is lagging, try to reduce the visual load. Turn off live wallpaper and heavy themes with active animation by going to the Themes app. Standard black or gray backgrounds often run faster.
Another important aspect is the speed of the window animations, and you can scale the animation from 1x to 0.5x on the developer menu, and it doesn't make the processor work faster, but it makes the interface more responsive visually. You have to click 7 times on the build number in the About Phone section to access these settings.
⚠️ Warning: Do not turn off system services in the Apps menu unless you know exactly what they are responsible for, which can cause communication to work unstable or notification icons to disappear.
☑️ Quick optimization of the interface
It's also worth checking the background processes. Some applications may be misbehaving after an upgrade, wasting resources. Go to the Battery and Performance section and see the consumption statistics. If you see an application that you didn't use but it ate the charge, force it to stop.
Managing Autoboot and Background Processes
Many users are unaware of how many programs run with the smartphone on. Autoloading a dozen apps loads RAM in the first minutes of operation, causing slowdowns. Limit this list to only the most essential messengers.
To manage your boot, go to Settings → Apps → Permissions → Autorun. Here you will see a list of all programs that start automatically. Leave only those that you need instant notifications from, such as Viber or Telegram, on.
| Type of application | Recommendation | Impact on speed |
|---|---|---|
| Messengers | Leave it on. | High (notification required) |
| Social media. | Shut down. | Medium (background synchronization) |
| Games | Shut down. | Low (not needed in the background) |
| Shops | Shut down. | Average (Update check) |
Why do you need a Memory Extender?
Also, keep an eye on desktop widgets: constantly updating news feeds, weather or currency rates requires constant access to the network and the processor, and if the phone is old, removing excess widgets can significantly improve performance.
Updating the system and applications
Xiaomi developers regularly release updates that often include bug fixes and code optimization. If your gadget is slowing down, check for new versions of the software in the About Phone section. Sometimes the problem is known to engineers and already solved in the patch.
But there's a downside: on very old models, newer versions of MIUI can work harder. If you upgrade and your phone gets worse, consider rolling back or resetting your previous version. It's also important to update all apps through Google Play or GetApps.
Outdated versions of apps may contain memory leakage bugs. Enable automatic updates in the app store settings to always have up-to-date and optimized versions of programs. This is especially critical for the system components of Google Play Services.
💡
Before a major system update, be sure to back up important data to your computer or the cloud to avoid losing information in the event of a crash.
Specificity of advertising and system debris
One of the reasons for the strain on Xiaomi phones is the built-in MSA (MIUI System Ads) advertising process, which consumes Internet and processor resources, and disabling this feature can slightly unload the device.
To remove ads, you need to turn off msa from the app menu. Go to Settings → Passwords and Security → Access to data, find msa and prevent data transfer. It is also recommended to turn off “Receive recommendations” in the settings of each system application (themes, music, Explorer).
- 🚫 Turn off personalization of ads in your Mi Account settings.
- 🧹 Use the built-in Security app to clean the cache.
- 📵 Remove pre-installed apps that you don’t use.
You don't need to install third-party accelerators from the app store. They often work on the principle of "wedge kicking out", loading the system even more with their background processes. Xiaomi's built-in tools are enough to maintain the cleanliness of the system.
Radical measures: reset to factory settings
If none of the above has worked and the phone continues to run slowly, the last effective method is a complete reset, which will return the device to the “out of the box” state, removing all the accumulated registry errors and file conflicts over the years.
Before you do this, be sure to save all the important data, as it will be permanently deleted. Go to Settings → About Phone → Reset → Erase all the data. The process will take a few minutes, after which the phone will turn on as new.
⚠️ Warning: Make sure that the battery level is at least 50% before resetting. interruption of the process during the formatting stage may result in the inability to boot the system.
💡
A complete reset is the most effective way to programmatically speed up an old smartphone, unless the problem is related to physical component breakdown.
After reset, take your time to install all the applications at once. Try running on a clean system for a couple of hours. If the speed is good, start slowly returning programs by observing the behavior of the device. Often, it is one particular application that is the source of all the problems.
When the problem is in the hardware
Sometimes software methods are powerless, and the reason lies in the physical wear and tear of the components. The main culprit here is the battery. Over time, the battery loses its ability to produce peak current, and the system artificially lowers the frequency of the processor so that the phone does not turn off under load.
It's also worth checking the temperature of the case. If the smartphone overheats, trottling (protective performance decline) will turn on, which can be caused by a dried thermal paste inside or a tight cover that interferes with the heat sink, in which case replacing the battery or cleaning internals in the service will help.
If the phone started to brake immediately after a drop or moisture, the software tips will not help, in this case, the plumes or memory contacts could be damaged, and diagnostics at an authorized Xiaomi center will help to accurately determine the condition of the iron.
