How to improve the performance of the Xiaomi Redmi 9A phone: an expert guide

Xiaomi Redmi 9A has become one of the most popular budget phones, but over time, even a reliable device can start to work slower. The MIUI shell is known for its functionality, but on entry-level models with limited RAM, it can create unnecessary load on the processor. Users often notice twitching interfaces, long start of applications and sudden closure of background tasks.

In this article, we will explore not only standard cleaning techniques, but also advanced techniques that will make the most of your gadget. System optimization requires a comprehensive approach: from removing system debris to fine-tuning animations, you will learn how to safely disable unnecessary services and prevent overheating, which often causes trolling.

Before we go to radical measures like factory resets, it's worth trying less aggressive methods. A good MIUI setup can do wonders, making slow work comfortable. Let's look at a step-by-step plan to help get your device back to speed.

Analysis and cleanup of system resources

The first step to speed up the Redmi 9A is to clean up the data in depth. Xiaomi's standard "Security" app works well, but often leaves too much. You need to manually check the folders with the cache of messengers and social networks, as they can take up gigabytes of space. The filled memory is the main enemy of the speed of any Android operating system.

Note the Other section in the repository, which often hides remnants of deleted apps and temporary update files, cache cleaning should be done regularly, especially if you are actively using a browser or streaming services, and don't be afraid to delete temporary files, it won't affect your personal photos or contacts.

⚠️ Warning: Don’t use third-party accelerators from Play Market that promise miraculous effects, they consume resources and display intrusive advertising, which only exacerbates the performance situation.

To effectively manage memory, you need to adopt a weekly maintenance habit, which is not time-consuming, but it significantly extends the life of the system.

• 🗑️ Delete. APK-Installation files left over after application updates.
• 📸 Transfer heavy video and photo to cloud storage or computer.
• 📱 Turn off autoboot for rarely used programs in settings.

Once the space is freed, the system will have the necessary margin for temporary operations, which is especially important for models with 32 GB of internal memory, where every megabyte counts.

Customization of interface and animations

The visual smoothness of the Redmi 9A is directly dependent on the animation settings. By default, the system is set to beauty, not speed. The hidden section for developers allows you to change the scale of the animation of the windows, transitions and duration of the animator, reducing these values creates the illusion of a faster response system.

To get to the desired menu, you need to click on the build number several times in the About Phone section. Once the developer mode is activated, go to the Additional → For Developers menu. Find the parameters related to the animation scale, and change them from the standard 1x to 0.5x or even “Disconnected” that will instantly speed up the navigation on the menu.

Also worth paying attention to the theme of design. Heavy themes with live wallpaper and complex widgets heavily load the GPU of a budget smartphone. Standard theme or minimalist wallpaper without animation is the best choice for increasing FPS in the interface.

💡

Use static black wallpaper on AMOLED-screens (if applicable) or simply dark static images to reduce battery and rendering processor load.

Remember that desktop widgets consume resources too, leave only the most essentials, such as hours or weather, and remove bulky news feeds.

Application and Autoboot Management

Control of running processes is key for devices with 2 or 3 GB of RAM, and many applications in MIUI are self-registered, which makes them work all the time even if you're not using them, resulting in fast battery life and a lack of free memory for active tasks.

Go to the battery settings and select each application. Set No Limits mode only for instant messaging messengers. For other applications, such as marketplaces or news aggregators, set background activity limits to prevent them from running in the background.

Pay special attention to the pre-installed software. Redmi 9A often has applications that you will never use, which can be disabled through the application management menu if deletion is not available, which will free up space and reduce the load on the processor when the system boots.

Regularly auditing installed programs helps keep the system clean, and if you don't remember why you need an application, you probably don't need it.

Special features and game settings

For gamers and users who want to be more responsive, there are special settings. You can add even heavy apps to the Game Turbo menu to prioritize their work. However, on Redmi 9A, it is important not to overload the processor, so balancing the graphics settings inside the games themselves is more important than external accelerators.

In the For Developers section, there's also the option "Do Not Save Activities," which if enabled, will destroy background activity immediately after release, which will free up RAM, but may lead to more frequent reboots of applications when you return to them.

Another important parameter is the limitation of background processes: you can manually set a limit on the number of processes, but it is better to leave the value of "Standard Limit" so that the system itself manages resources based on the current load.

⚠️ Attention: Including debugging by USB And changing hidden settings may affect some banking applications or security features.

Experiment with settings consistently, checking the results after each change, which will help you find the optimal balance between speed and stability.

Table of comparison of optimization methods

So that you can choose the most appropriate way to accelerate, we have prepared a comparative table that will help you assess the effectiveness and complexity of each method for your particular situation.

As you can see from the table, simple actions like turning off animations produce a noticeable visual effect without the risk of data loss. Fundamental measures like resetting maximize the gain, but take time to reset.

Radical measures: Resetting and updating

If the software methods don't work, the final frontier is a complete factory reset, and before that, make sure to back up all the important data, which deletes all user files, settings and apps, returning the phone to the "out of the box" state.

Also check for system updates. Xiaomi engineers are constantly releasing patches that fix optimization errors. Go to Settings → About Phone → System Update and check for a new version of MIUI. Sometimes the new firmware is faster than the old one thanks to improved memory management.

After reset, don't install all the applications at once. Start with the basics and observe the behavior of the system, which will help identify the "heavy" application if the problem recurs.

💡

A complete reset is not a panacea, it's a tool, and if the problem is physical memory wear or overheating, a software reset will only have a temporary effect.

Use this method only when other methods have been exhausted, and proper preparation for the reset will save you nerves and time.
