What to do if the phone Xiaomi is very much lagging: an expert solution

The situation when the once-fast smartphone suddenly starts to work slowly, familiar to many owners of Xiaomi equipment. Sudden friezes of the interface, long opening of applications and delays in typing can turn using the device into a real test, most often the problem lies not in hardware failure, but in software conflicts or overflow of system partitions.

The current MIUI shell (and its new version of HyperOS) has powerful features that require significant resources to run smoothly. If you notice that your Xiaomi Redmi Note or Xiaomi 13’s flagship has started to slow down, don’t rush to bring it to the service center. In most cases, the situation can be fixed by software methods.

In this article, we will discuss a step-by-step algorithm that will help restore the device to its former speed, and we will look at both standard cleaning tools and hidden developer settings, which are often ignored by users.

Diagnosis of the problem: why the smartphone slows down

Before you start to act, you need to understand the source of the problem: lags can be caused by overheating of the processor, lack of RAM or errors in the operation of system processes. Overheating is one of the most common causes, because when the temperature rises, the processor forcibly resets the frequencies to avoid damage.

Also worth noting is the background activity of apps, which is that many programs continue to work even after they are closed, consuming resources and Internet traffic, and this is especially true for social networks and instant messengers, which are constantly updating content.

• 🔥 Overheating of the body and throttling of the processor
• 📉 Overflow of the section "Memory" (more than 90% occupied)
• 📱 Unoptimized or "heavy" versions of applications
• 🐛 Errors after firmware update MIUI

If your phone gets hot even when it's not, it might be a faulty battery or a short circuit on the board, and then software cleaning won't help, and you'll need a diagnostic in the service.

⚠️ Note: If the lags appeared immediately after the system update, wait 24-48 The system indexes files and optimizes applications in the background, which temporarily reduces performance.

Check the battery usage statistics in your settings. If an application consumes a disproportionate amount of power or CPU time, it may be the one that is responsible for the brakes.

Basic cleaning of system and cache

The easiest and most efficient way to speed up work is to free up disk space. Android requires free space to create temporary files and swaps. If a partition is crowded, the speed of reading and writing data drops dramatically.

Use Xiaomi's built-in Security app, which can find and remove system debris that accumulates as your browser and social media work, but don't rely on automatic cleaning alone.

Pay special attention to instant messengers. Telegram and WhatsApp often take up gigabytes of space, saving all the photos and videos you viewed. Go to the settings of these applications and find "Memory Use" to delete old files.

It also makes sense to remove unused apps, even if you don't use them, they can run background services, remove games you've long abandoned and heavy apps you use once a year.

• 🗑️ Removing duplicate photos and screenshots
• 🧹 Cleaning the cache through Settings → Annexes
• 📂 Transferring media files to your computer or cloud
• 🚫 Removal of pre-installed software (bloatware)

Don't forget to clean the Download folder regularly.APK installer files, old documents and saved images from the internet often lie dead weight there.

Optimization of MIUI and HyperOS interface

Visual effects make the interface enjoyable, but they also consume GPU resources. If the phone is old or has a weak processor, turning off animations can greatly improve the responsiveness of the system.

To access hidden settings, you need to activate the developer menu. → About the phone and quickly press 7 times on the item "Version" MIUI" (or "Version". OS"). After that, a new section will appear in the settings menu "Additional" →"For developers".

In this section, find the animation zoom options, change the values of "Window animation", "Jump animation" and "Duration animation" from 1x to 0.5x, or completely disable them, which will make switching between screens instantaneous.

⚠️ Note: Do not change the settings associated with debugging USB Or the processes that you're not sure about, if you're not sure what they're going to do, and that can cause the system to be unstable.

It’s also worth checking the RAM expansion settings, which uses a portion of the internal memory as virtual RAM. On older and slower drives, turning on this option can, on the contrary, slow down the phone due to the slow read speed.

Managing Autoboot and Background Processes

Many apps tend to start right after the phone is turned on, which slows down the system load and consumes battery power. Xiaomi has a powerful tool in its shell to monitor autoload.

Go to the Security app, select Permissions → Auto Start. Leave only those apps that need to come by notification instantly (like messengers or alarm clocks) on.

Also, check the list of applications that are allowed to run in the background. To do this, go to Settings → Apps → All apps, select an unnecessary program, and find “Activity Control.” Set a background activity restriction.

• 🚫 Disabling Autoplay for Games and Stores
• ⛔ Limiting background work for rarely used programs
• 🔋 Configure energy saving for each application
• 📵 Disabling Synchronization in the Background for Cloud Services

An effective strategy is to manually close heavy apps after use. While Android can manage memory itself, on devices with a low RAM capacity (up to 4 GB), manually closing maps, navigators and video editors helps avoid lag.

Impact of Advertising and System Services on Productivity

One of the features of MIUI is the availability of advertising services (MSA – MIUI System Ads), which are constantly working in the background, collecting data and downloading advertising content, which can put strain on the processor and network.

To improve performance, it is recommended to disable personalized advertising. Go to Settings → Passwords and Security → Access to personal data and find the msa process. Turn off the switch and wait 10 seconds, then confirm the action.

💡

Expert advice: Turn off My Reviews and Screenshot Receiver services in the same menu if you don't use them, too, which will reduce the number of background tasks.

Also worth checking is the list of running services. Some system applications, such as Scanner, Cleanup, or Mi Browser, may be hanging in memory. They can be stopped through the application menu, but they will run again the next time you use them.

Disabling these services will not only speed up the phone, but also extend the battery life, and you will notice that the device will become less heated in standby mode.

Radical measures: resetting and reflashing

If the software cleanup didn’t work, it may have accumulated critical file errors or conflicts after a lot of updates, in which case the solution would be a full reset.

Remember: make sure to back up all important data to your computer or cloud before reset, as the phone will be cleaned completely.

To perform the reset, go to Settings → About Phone → Settings Reset → Erase all data. The process will take about 10-15 minutes. Once turned on, you will get a clean system that works like the first day of purchase.

In extreme cases, when even a reset does not help or the phone "catch a cyclical reboot", you need to flash through the computer using the Mi Flash Tool utility. ADB-team.

If you are not sure of your abilities, it is better to consult specialists. Wrong firmware can turn a smartphone into a “brick”, recovery of which is possible only at the hardware level.

💡

Complete data reset eliminates 95% of software lag caused by garbage accumulation errors and update conflicts.
