How to speed up the application to Xiaomi: the complete guide

Modern Xiaomi smartphones, which are based on the shells MIUI or the new HyperOS, have huge potential, but even powerful hardware does not always guarantee smooth operation of the software. Users often face a situation when a particular application is launched for a long time, runs in jerks or suddenly shuts down, which is especially annoying during games or video calls.

Owners of Redmi, POCO, and Xiaomi know that MIUI is notorious for its resource gluttony and complex permission management system. Optimizing applications requires a holistic approach, from customizing developer settings to manually managing the power consumption of each individual process, and ignoring these settings means that even the top-end Snapdragon or MediaTek processor can’t reach its potential.

In this article, we’ll look at proven techniques that will help you eliminate lags and improve performance.We won’t offer installing questionable accelerators from the Play Market, as they often harm the system.Instead, you’ll learn to competently manage Android’s built-in tools and proprietary shell features to make even heavy programs fly.

Analysis of the causes of low productivity

Before we take any drastic action, we need to understand what is causing the slowdown, and most often the culprit is a crowded app cache that accumulates gigabytes of temporary files that prevent quick access to data. Over time, the database inside the program grows, the indexes are lost, and the system takes longer to find the information it needs.

Another common reason is a lack of free RAM: MIUI and HyperOS shells actively use the memory compression mechanism, but if you run a dozen background applications, the current window simply does not receive enough CPU resources. Background processes can eat up to 60% of the available power, especially if it is heavy messengers or navigators.

If the smartphone body is hot, the system automatically reduces the processor frequency (trottling) to avoid damage to components, in which no optimization will help until the temperature drops to normal values.

• 🔥 Overheating of the processor due to prolonged load or use in the sun.
• 🗑️ Overcrowded storage with less than 10% of the space available.
• 📉 An outdated version of the app that is not optimized for the current Android.
• ⚡ Aggressive energy saving settings that kill background services.

Importantly, on older smartphone models, newer versions of apps may be slower simply because of the increased system requirements of software developers, in which case only finding lighter versions of programs or rolling back to previous versions of APK helps.

Cleaning the cache and application data

The easiest and safest way to speed up the program is to force the cleaning of accumulated garbage. Unlike the standard cleaning through “Security”, deep cleaning through settings allows you to remove exactly those files that slow down a particular software. To do this, go to the Settings menu → Apps → All applications and find the desired program in the list.

On the app information page, you'll see the "Clean" button. When you click on it, select "Clear Cache" -- this action is safe and won't delete your logins or game progress. However, if the problem persists, you can try a more radical method, "Clean all data."

⚠️ Warning: Clear All Data will reset the application to a state immediately after installation, you will lose saved passwords, in-program settings, and local saves if they are not synced to the cloud.

Once cleaned, the system will restructure the application file structure, which often solves problems with friezes when scrolling through tape or opening heavy pages, and doing this routine once a month helps maintain high speed.

💡

Before completely clearing the data of an important application (such as a messenger), be sure to back up through Google Drive or the internal chat export function.

Configuring autonomy and energy saving

MIUI and HyperOS have very aggressive energy saving policies that by default limit the background activity of applications, which is done to increase battery life, but often causes the application to fall asleep and wake up for a long time, creating the illusion of braking. To speed up the response, you need to change the battery settings for a particular application.

Go to Settings → Battery and Performance (or simply “Battery”) and find a list of applications. Select a problem program and find “Energy Saving”; the default is often “Energy Saving” or “Smart Savings.”

You need to switch mode to "No Limits" so that the app can use the processor at full power and run in the background without artificial delays, and you should also enable auto-run for those programs that you use all the time.

After changing these settings, the system will stop “smothering” the application’s background processes, which is especially critical for navigators, pedometer trackers and instant messengers, which must work constantly.

Use of the “No Limits” regime

The new versions of HyperOS and MIUI 14 have a separate feature that allows you to completely remove the restrictions on background work. It is not the same as battery setup, it is a deeper level of control over the system. You can find it by Settings → Apps → Settings → Special features (the path can vary depending on the OS version).

By enabling unlimited mode, you ensure that even when memory is scarce, the system will be the last to shut down the application, which is useful for heavy games or video editing programs, where process stability is important.

• 🚀 Priority allocation of processor cores.
• 🛡️ Protection against forced closure by the system.
• 🔋 Permit to work in the background without restrictions.
• ⚙️ Reduced frequency of context switching.

It is worth remembering that turning on this mode for a large number of applications can lead to a faster battery discharge, as the system will stop optimizing their operation.

Optimization through the Developer Menu

For advanced users who want to make the most of their Xiaomi, there are hidden developer settings that allow you to manage animations and background limits at the system level, and to get there, you need to click 7 times on the build number in the About Phone menu.

In the developer menu, find the Drawing or Hardware Acceleration section, where you can turn off window and transition animations, which will visually speed up the interface and application response, and the Background Process Limit option is also useful, setting a value of No More than 2 Processes to free up memory for an active task.

Special attention should be paid to the 4x MSAA option (if available on your device), it improves graphics in games, but can reduce performance. To speed up older games, you can try to turn it on, but for heavy novelties, it is better to leave it off.

Path to menu: Settings → About phone → 7 clicks on "Version MIUI" → Additional settings → For developers

Be careful with the settings in this section: changing the rendering settings or DPI scale can make the interface unreadable or cause system failures.

💡

Disabling animations in the developer menu is the fastest way to visually speed up the interface without losing functionality.

Comparison of optimization methods

So that you can choose the most appropriate way to solve the problem, we have prepared a comparative table of methods, each of which has its own advantages and risks that should be considered before applying.

As you can see from the table, the safest and most effective method for regular use is a combination of cleaning the cache and setting up energy savings, and radical measures should be applied only in case of serious failures.

Additional Tips and Game Turbo

For gamers, the MIUI shell features a Game Turbo tool that automatically detects running games and redistributes system resources, disabling notifications and clearing memory. Make sure your app is added to the list of games in the Security app.

It’s also worth checking for updates to the system itself and Google Play Services. Often, performance issues of specific apps (especially Google Maps or YouTube) are due to bugs in Google services that are patched.

If nothing helps, consider installing an alternative launcher or resetting your network settings, as slow internet is often perceived by the user as the brakes on the app itself.
