How to remove lags on Xiaomi: an expert guide to speeding up a smartphone

Xiaomi, Redmi and POCO are popular for their excellent price-to-performance ratio, but even powerful devices are slowing down over time. Users often experience interface slowdowns, long app launches and sudden hang-ups, which is especially annoying in the dynamic rhythm of life. The main reason lies in the accumulation of system debris, memory fragmentation and the peculiarities of the MIUI or HyperOS shell.

Before you bring your gadget to a service center or think about buying a new model, you should conduct a comprehensive software optimization. In most cases, eliminating lags does not require deep technical knowledge, but only careful follow the instructions for cleaning and configuring the system.

In this article, we’ll look at proven methods to help you get your phone back on track, and we’ll look at both standard cleaning tools and hidden Android features that not all owners know about.

Diagnosing the causes of low productivity

The first step to solving the problem is understanding it, which can be caused by a lack of RAM, overcrowded internal storage or background processes that eat up CPU resources. MIUI shell is known for its functionality, but the abundance of widgets and services sometimes comes with performance costs, especially on low-cost models with low RAM.

A common mistake of users is to ignore updates or, conversely, install “heavy” beta versions of firmware on weak iron. Also, it is worth considering the physical wear of the drive: after several years of active writing and reading data, the speed of their processing can significantly decrease, which directly affects the speed of the entire system.

⚠️ Warning: If the smartphone starts to heat and brake at the same time, the problem may not be only software.

To pinpoint the bottleneck, you can use built-in tools or third-party tools like CPU-Z or AIDA64 to show the current core load and temperature, which will help you choose the right lag control strategy. If the processor is constantly loaded 80-90% even in a simple one, then some process requires your intervention.

Basic cleaning of system and cache

The easiest and safest way to remove lags on Xiaomi is to use the built-in Security app. Despite some experts’ skepticism about embedded cleaners, in the Xiaomi ecosystem, this tool is deeply integrated into the system and effectively deletes temporary files that are not visible when manually checking folders.

Start an app, select Clean up, and wait until the analysis is complete, and the system will prompt you to delete the cache of applications, remnants of deleted programs and advertising files, and it's important not just to click the cleanup button, but to analyze the list: sometimes there are cache cards or offline music that you plan to use.

  • 🗑️ Delete the cache of heavy apps (social networks, browsers) regularly, as they can grow to several gigabytes.
  • 📂 Check the Download folder – installations often accumulate there. APK-files and forgotten documents.
  • 📸 Free up gallery space: A full storage (over 90%) critically slows down the file system.

Remember, the Acceleration feature in the same app, which forces the background to close, freeing up RAM. While Android can manage memory itself, on shells with active background activity, this tool gives a tangible increase in performance “here and now”.

Optimization through Developer Settings

For more advanced users, hidden Android features are open to make the interface work both visually and in fact faster. To get into the developer menu, you need to click on the build number several times in the About Phone section, and then a new “Developers” option will appear in the advanced settings.

In this section, we're interested in animation options. Find the paragraphs "Window animation", "Endover animation" and "Duration of animation." By default, they are set to 1x. Changing the value to 0.5x or completely disabling (0x) makes the interface visually faster, as it reduces the time of rendering transitions between screens.

Setting a limit of background processes to a value of “No more than 4 processes” can significantly free up RAM on devices with 3-4 GB of RAM, but this will lead to more frequent reboot of tabs in the browser.

Also, you should pay attention to the switch “Speed up work”. GPU» (Force GPU rendering. This function shifts some of the rendering tasks. 2D-On older models, this can be an increase, but on modern chips, the effect may be invisible or even lead to increased battery consumption.

Should I include a "Strict mode"?
Enabling Strict Mode highlights flashing red squares when the app loads the main stream, which is useful for developers, but the average user will only create visual noise and will not speed up the phone.

Managing Autoboot and Background Processes

One of the main reasons why Xiaomi’s phone starts to lag some time after purchase is the uncontrolled auto-run of apps. Many programs prescribe themselves to start-up to constantly hang in memory, send notifications or collect data, which creates a constant load on the processor.

In the battery and performance settings (or in the "Security" -> Battery app), you can adjust the behavior of each application. It is recommended to manually disable autorun for all programs except messengers and alarm clock, which will prevent the situation when after a restart the phone starts "thinking" for several minutes, running dozens of services.

  • 🚫 Turn off auto-start for games, shops, and rarely used utilities.
  • 🔋 Set the power saving mode “No restrictions” only for important messengers so that messages arrive on time.
  • 📉 Use the Advanced Memory Cleaner in the Developer Settings to Force Service Closure.

Special attention should be paid to the Memory Extension feature, which is available in newer versions of MIUI and HyperOS. It uses some of the permanent memory as virtual RAM. If you have little physical RAM (4 GB or less), turning on this feature can help, but if the storage is full, it is better to leave it off so as not to slow down the reading of data.

💡

Check the Usage Statistics section in your battery settings periodically, if the app you weren't using was a lot of power, it's a sure sign of malicious activity or a failure that needs to be removed.

Comparison of optimization methods

There are many ways to improve the response of the system, but their effectiveness depends on the specific model and version of the firmware. Below is a table that will help you choose the most suitable method for your situation, assessing the risks and the expected outcome.

As you can see from the table, radical measures are better, but they require preparation. Easy methods, such as tuning animations, are safe and give an instant, albeit subjective, acceleration effect. Combining methods allows you to achieve the best balance between speed and stability.

You don't want to go for benchmarks, but the goal is to be comfortable, and if the interface is smoother and apps are faster, then the optimization has been successful, regardless of the numbers in the tests.

Radical measures: resetting and reflashing

If the software cleaning doesn’t work, the final argument in the struggle for performance is a complete reset (Wipe Data), which will return the smartphone to the “out of the box” state by removing all accumulated software debris, conflicting settings and remnants of remote applications.

Before the procedure, it is critical to back up data. In Xiaomi smartphones, this can be done through the Mi Cloud cloud or locally, saving the data to a computer or external drive. Once reset, the phone will work as quickly as possible, as the file system will be cleaned and defragmented.

⚠️ Warning: Full reset deletes ALL data, including photos, contacts and apps. Make sure you have an up-to-date backup before clicking the "Erase Everything" button».

In extreme cases, when even the reset does not help (for example, hardware problems or damage to system partitions), it may be necessary to flash the device through the computer using the Mi Flash Tool utility. This is a complex process that requires unlocking the bootloader, and beginners should contact specialists so as not to turn the phone into a “brick”.

💡

Full reset (Factory Reset) is the most effective means of combating software lags caused by prolonged operation and accumulation of errors in the system.

Frequently Asked Questions (FAQ)

Why does the new Xiaomi stop immediately after purchase?
In the first days after the switch on or update, the system indexes files and optimizes applications in the background, which can last from a few hours to 2-3 days of active use.
Does installing accelerators from the Play Market help?
Most of the time, it's not. Android and MIUI are built-in memory management, and third-party boosters often consume resources and display ads to make it look like they're working.
Does memory overflow affect the speed of work?
Yes, it's critical. 10-15% from the total amount of internal memory, the speed of writing and reading data drops at times, which causes strong lags throughout the system.
Should I turn off system updates for speed?
Updates often contain security patches and performance optimizations, and by disabling them, you risk running into vulnerabilities and bugs that have already been patched in the new version.
How often should I reboot my Xiaomi smartphone?
For stable operation, it is recommended to restart the device at least once a week, which allows you to clear the RAM from “stuck” processes and update system services.
