The situation when the once-quick Xiaomi suddenly starts to slow down is familiar to many users. Yesterday the interface flew, and today opening a gallery or messenger turns into torture with long expectations.
Most often, the problem lies in software conflicts, crowded cache or aggressive optimization of MIUI and HyperOS. Understanding the reasons allows you to eliminate lags without visiting the service center. In this article, we will discuss all the methods, from simple reboots to deep tuning of hidden parameters.
Before you panic, even flagship models can slow down after a major operating system update, while optimizing applications in the background can take hours to days, and if the problem persists longer, user intervention is needed.
Primary diagnostics and system updates
The first step is always to reboot the phone in a simple but effective way, and many people ignore this advice, but it is the reboot that cleans the RAM of the dead processes and temporary files. If the phone hasn't turned off for a long time, the RAM accumulates "digital garbage" that directly affects the speed of the processor.
The second critical point is software version control. Often, the bugs that cause friezes are fixed in security patches. Go to Settings → About your phone and click on the MIUI or HyperOS version. The system will check for updates itself.
💡
If you don’t get an automatic update, try changing your region to India or Singapore, sometimes the servers in these locations give up the firmware faster.
However, if you’ve just upgraded and your phone is starting to glittle, the problem may be that the old version of Android is not compatible with the new shell, in which case it’s advisable to wait 2-3 days for background optimization or consider resetting.
⚠️ Do not interrupt the process of installing updates and make sure that the battery charge is above 50%, otherwise there is a risk of turning the smartphone into a brick".
It's also worth checking if the device is overheating. At high temperatures, the processor artificially lowers the frequencies (trottling), which causes severe lags. Remove the case and let the gadget cool if it's hot to the touch.
Memory Cleanup and Storage Optimization
A full internal drive is one of the main reasons why Xiaomi is slowing down: when it is less than 10-15% free, the speed of writing and reading data drops, which affects the entire system.
Run the scan through the built-in tool and click "Clean" and pay special attention to the "App Cache" and "Big Files" section, often forgetting about downloaded videos or old APK installation packages.
☑️ Cleaning memory in 5 minutes
Remember messengers. Telegram and WhatsApp tend to grow to giant sizes, saving every photo and video you see. Inside the settings of these apps, find the "Data Use and Storage" item and clear the media cache.
| Type of data | Impact on speed | Recommended action |
|---|---|---|
| System cache | High (slows launch) | Cleaning up through Security. |
| Photos and videos | Average (seat occupation) | Transfer to the cloud or PC |
| Annexes | High (background processes) | Removal of unused programmes |
| Files.apk | Low (just taking up space) | Remove after installation |
If built-in tools are scarce, you can use disk space analyzers to visually see which folders occupy the most megabytes, which can help you find forgotten downloads or error logs.
Managing Autoboot and Background Processes
MIUI is famous for its aggressive energy-saving policies, but sometimes it works the other way around, forcing applications to hang in the background and consume resources.
Go to Settings → Applications → All applications. Select heavy programs (social networks, marketplaces) and find the "Start" option. Turn it off for anything that shouldn't be turned on by itself. This will reduce the load on the processor when you turn on the screen.
It is also useful to limit background activity. In the charge saving menu, you can set a limit for each application "No restrictions" only for messengers, and for the rest - "Limit background activity."
The Virtual RAM feature, which takes some of the permanent storage into RAM, is a feature that, paradoxically, can reduce performance on older models with slow eMMC memory. Try turning it off in the "Advanced" settings.
⚠️ Warning: Disabling system processes like “Mi Cloud” or “Xiaomi Services” can lead to unstable synchronization and theme store.
Customization of animation and MIUI interface
Visual smoothness is often perceived as speed, and if the animations are too heavy or too complex, the phone will seem slow, and you can speed up the rendering of windows in the developer menu.
To access hidden settings, you need to click on the build number 7 times in the "About Phone" section, and then the "Developers" section will appear in the advanced settings.
- 🎨 Window animation
- 🔄 Transition animation
- ⏱ Duration of the animator
Set a 0.5x or even Off value for all three, and the interface will be sharper and more responsive, especially for the Redmi and Poco budget models.
How to turn on the developer mode without a menu?
Another important aspect is the refresh rate of the screen. If you have a model that supports 90 Hz or 120 Hz, make sure that the screen settings select the default or 120 Hz mode, not 60 Hz. However, if the battery goes down too quickly, reducing the hertz can extend the life of the device, although it will make the picture less smooth.
Using themes and live wallpaper also loads the GPU, and if the phone is old, switching to static black wallpaper and a standard theme will make life much easier for the system.
Combating System Advertising and MSA
Xiaomi Advertising Services (MSA — MIUI System Ads not only annoy, but consume CPU traffic and resources to load targeted ads.
You need to turn off ad personalization. Go to Settings → Passwords & Security → Access to Personal Data. Find the msa process and turn off the slider. The system will ask you to wait 10 seconds, then confirm the disconnect.
You should also go through the built-in apps: Music, Themes, Explorer, Downloads. In the settings of each of them (usually in the corner three dots or gear) you need to find the item "Receive recommendations" and turn it off.
⚠️ Attention: After disconnection MSA Advertisements may not disappear immediately, but within 24 hours.
Disabling unnecessary notifications from system applications will also unload the processor, check the notification center and prevent ads from showing for applications you rarely use, which will reduce interruptions and background downloads of content.
Resetting and radical measures
If the software methods didn’t help and Xiaomi continues to slow down, the final software argument is a complete factory reset, which will delete all data, so be sure to back up important contacts and photos.
💡
Hard Reset eliminates 90% of the software errors and conflicts accumulated over the years of using a smartphone.
Go to Settings → About Phone → Reset. Select "Erase All Data." It takes a few minutes to make the phone look like new, and often after that, even the older models start to work noticeably faster.
In extreme cases, if the problem is in the hardware (degradation of flash memory or overheating of the processor), the software methods will be powerless, in this case, only the soldering of memory in the service or replacing the device will help. However, before buying a new one, you should try flashing through the computer (Fastboot ROM), which is a deeper cleaning than a conventional reset.
Regular maintenance, no crowded memory and a competent setup of animations will allow your Xiaomi to stay fast for many years.Do not ignore the first signs of slowing down, as it is easier to fix the problem early.
