Many Xiaomi smartphone owners sooner or later face a situation where the once-quick device begins to work slowly. MIUI interface, despite its functionality, can eventually become "garbage", and background processes begin to consume resources necessary for smooth operation. Brakes in the system can manifest themselves in different ways, from long application launches to delays in typing.
In this article, we will look at why Xiaomi is lagging and how to get the device back to speed. We will not use complex terms without explanation, but rather look at the real reasons, which lie in both software settings and hardware limitations. Android optimization is a process that requires understanding what exactly loads the processor.
Before you bring your phone to the service, you should try software solutions. Often the problem lies in a crowded memory or a conflicting application. Analysis of the reasons will save you time and money by returning the gadget to a comfortable speed without radical measures.
Internal memory overflow and cache
One of the most common reasons Xiaomi is slowing down is when internal memory is critically filled. 10-15%, The operating system has difficulty creating temporary files and swap data. The system partition no longer effectively manages the flow of information, which leads to noticeable delays.
This is especially true for models with a storage capacity of 32 or 64 GB. High-resolution photos, messenger cache and downloaded video files quickly take up useful space. The threshold of 3-4 GB of free space is critical for the stable operation of MIUI. If you ignore the warnings about the shortage of space, the lags will become permanent satellites of the interface.
To solve the problem, you need to clean the app cache regularly, and this can be done through the standard Security app, which is pre-installed on all smartphones of the brand. Cleaning the cache will not delete your personal data, but will free up space from temporary files accumulated during use.
- 📱 Go to Settings and select Memory».
- 🗑️ Use the built-in “Cleanup” tool to remove garbage.
- 📸 Transfer photos and videos to a memory card or cloud storage.
- 🗑️ Remove apps you haven’t used for more than a month.
Also worth looking at is the Downloads folder, which often stores APK installation files and old documents, which can instantly free up a few gigabytes of storage, and regular memory hygiene is a guarantee of no lag in the long run.
Background processes and application performance
The second major reason for slowing down is the excessive amount of running background processes, and many applications, even if you don't use them right now, continue to run in the background, consuming RAM and CPU resources, and social networks and instant messengers are considered particularly voracious.
In the MIUI shell, there's a memory extension feature that takes some of the internal memory for RAM. However, if the physical memory is full, it can, on the contrary, cause micro-freezes. Virtual memory is slower than the physical memory, so you should rely on it with caution.
To understand what's loading a system, you can use a developer menu or third-party resource monitors. Often, one heavy app is blocking others. Auto-run programs are another enemy of speed that you need to control.
It is recommended to manually disable auto-start for applications that do not need to run constantly, this can be done in the battery settings or through the application menu.
- ⚙️ Open the application settings and find the "Battery" item».
- 🚫 Select “No Limits” mode for important messengers only.
- 🛑 For other applications, install “Energy Saving».
- 🔄 Turn off auto-update apps in the Play Market via mobile network.
Remember that some viruses and miners can disguise themselves as system processes. If the phone warms and lays even in plain, it is worth conducting a full antivirus check.
Problems after MIUI update
Often users notice that the Xiaomi phone began to slow down immediately after the firmware update, which is normal for the first days after the release of the new version of MIUI. The system indexes files, optimizes databases and rebuilds the work of background services for new algorithms.
Optimization can take anywhere from a few hours to a couple of days, depending on the memory capacity and processor model, during which the case may be heated and battery consumption is increased, and the system takes time to adapt, and it is not recommended to interfere with this process.
However, if the lags don't go away after a week, the update may have been installed with an error or contains bugs, and in such cases, resetting to factory settings helps, but only after you have created a full backup. Clean installation often solves problems accumulated over the years using the old version of Android.
Should I go back to the old version?
Also, newer versions of shells often require more powerful hardware. If you have a budget model three to four years ago, the latest version of MIUI may be too heavy for it, in which case custom firmware or on the old version may be the way out.
Hardware restrictions and overheating
You can't discount the physical condition of the device, because over time, the heat paste inside the smartphone dries up, and the cooling system takes away the heat worse, and when it overheats, the processor automatically resets the frequencies to keep from burning, causing FPS and laga to plummet.
This is especially true in games or long-term video shooting, and if the phone is hot to the touch and the interface is late, it's a sign of trotting, and heat throttling is a protective mechanism, but it has a big impact on the user experience.
In addition, battery degradation can lead to unstable voltages, which also affect performance: older batteries can not give current at the desired speed at peak times of load, battery wear indirectly affects the operation of the entire device.
| Symptoms. | Probable cause | Method of decision |
|---|---|---|
| Lags only in games | Overheating or lack of RAM | Lower your schedule, take off your case. |
| Brake the entire interface | Memory overload | Clear the storage, remove the cache |
| Friezes after the calls | Communication module error | Resetting network settings |
| Freezes when charging | Poor quality cable/block | Replace the charger |
If the phone is old, you might want to consider replacing the battery in an authorized service, which can give the device a second life and remove the lag associated with power shortages.
Animation and Visual Effects Settings
MIUI is famous for its beautiful yet heavy animations. On powerful flagships, they are invisible, but on budget models they can create the illusion of slow work. Turning off or speeding up animations is an easy way to make the interface more responsive.
To do this, activate the developer menu. Click 7 times on the build number in the About Phone section. Then, in the advanced settings, look for Developer's. The animation scale is a parameter that we'll change.
Find three items: "Window animation," "Transition animation," and "Duration animation." The default is 1x. Change it to 0.5x or completely disable it. Visual response becomes instantaneous, creating a sense of faster performance.
💡
Disabling animation not only speeds up work, but also saves battery power, since the processor spends less time on rendering intermediate frames of the interface.
Also in the Advanced Settings section, there's a special feature, where you can turn off visuals like shadows, background blur and live wallpaper, and static backgrounds are much faster than dynamic.
- 🎨 Remove the “live wallpaper” and replace it with a static image.
- 🌑 Turn off the dark theme if it works through inversion (on older Android).
- 📉 Reduce the number of widgets on the desktop.
- 🚫 Remove heavy themes from third-party sources.
⚠️ Warning: Disabling system animations completely can make the interface less understandable, as visual cues about transitions between screens will be lost.
Radical measures: Resetting and reflashing
If software methods don't work, the last thing you can do is reset the entire factory, and this action will remove all the data, applications and settings, and put the phone back out of the box. Factory Reset is the most effective way to deal with software debris.
Before the procedure, make sure to back up your contacts, photos and important documents, you can use the Mi Cloud or Google Drive cloud service, and data retention is the number one priority before resetting.
You can reset through the settings menu in About Phone -> Reset. Select "Erase all data." The process will take a few minutes, after which the phone will turn on as new. The clean system will work as fast as possible.
☑️ Preparation for discharge
In some cases, flashing the device through the computer using the Mi Flash utility helps, which allows you to install a clean version of the firmware without system debris, but it requires certain skills and carries risks if you interrupt the process.
⚠️ Warning: Flashing through Mi Flash can unlock the bootloader, which will lead to loss of warranty and inability to use some banking applications without additional manipulations.
