How to Speed Up Xiaomi Redmi 9: A Complete Optimization Guide

Owners of the popular budget smartphone often face slowdown of the interface after a year or two of active use. the Redmi 9 model, released on the processor MediaTek Helio G80, was originally positioned as a reliable device of the middle segment, but over time, the accumulation of system debris and update applications can significantly reduce performance. Understanding the causes of the slowdown is the first step to restore the former sharpness of the device.

There are many software methods to extend the life of a gadget without the need to buy new hardware. In this article, we will detail the safe ways to clean up memory, adjust animations and control background processes that will return your Redmi 9 performance.

Analysis of the causes of low productivity

Before we take decisive action, we need to understand what exactly is loading the system. The Android-based MIUI operating system has its own resource management features that differ from pure Android. Often users install heavy widgets themselves or leave dozens of apps in autoboot, which critically affects RAM.

One of the main reasons is internal storage overflow: When disk space falls below 10-15%, data write and read speeds drop dramatically, causing micro-freezes when running programs, and it is worth considering that modern versions of social networks and instant messengers are becoming increasingly demanding on the processing power of the processor.

⚠️ Warning: Don't install questionable accelerator apps from Play Market that promise "instant power gains." Most often, they consume resources and display intrusive advertising, only exacerbating the problem.

It's also important to check the battery status. Battery degradation can lead to trottling, a forced processor frequency reduction to prevent a sudden shutdown. If your Redmi 9 has been around for a few years, it may be because of the wear and tear of the battery.

Cleaning the system and memory management

The most efficient and safe way to get back up is to clean the system of temporary files in depth. The MIUI has a powerful tool built in to do this, which is often ignored by users. Regular use of a regular cleaner helps keep the system in good shape.

To start, you need to open the standard Security app and select Cleanup. The system will analyze the files and suggest removing the cache, remnants of deleted programs and advertising debris.

β˜‘οΈ Checklist for quick cleaning

Done: 0 / 4

Special attention should be paid to the cache of social networks such as Telegram and WhatsApp, which can accumulate gigabytes of data that are not visible during normal file browsing, and inside the settings of each messenger there is a section "Data and memory", where you can safely clear the cache without losing correspondence.

  • πŸ—‘οΈ Remove old screenshots and downloaded files from the Download folder, they often take up the lion’s share of the space.
  • πŸ“± Turn off auto-update apps via mobile network in Google Play settings so as not to waste processor traffic and resources.
  • πŸ”„ Reboot your smartphone at least once a week to reset temporary processes and clean RAM.

Remember the recently deleted folder in the gallery, where the files you deleted are stored for 30 days, taking up precious space on the built-in drive, and cleaning up the cart completely can free up a few gigabytes instantly.

Optimization of MIUI settings and animations

The visual component of Xiaomi's interface also consumes graphics accelerator resources. Beautiful transitions and blur effects create smoothness, but on budget processors can cause delays. Disabling or accelerating animations is a proven method of visual acceleration.

To access hidden settings, you need to activate the developer mode. To do this, go to the Settings β†’ About menu and quickly click on the MIUI version seven times. After that, a new section for developers will appear in the advanced settings.

In the menu that opens, find the animation scale settings. You need three items: "Window animation," "Jump animation," and "Animation duration." The default is 1x. Change it to 0.5x or completely turn off the animation for maximum performance.

Hidden Developer Settings
In the developer section, you can also find the item "Background processes." Set a limit "No more than 4 processes" if you are not using multiple applications at the same time. This will free up RAM for the active task.

Another important feature is RAM expansion, and newer firmware versions for Redmi 9 include Memory Extension, which is part of the internal memory for virtual RAM, which can help, but only if you have enough free RAM.

  • βš™οΈ Reduce the scale of animation to 0.5x for instantaneous interface response.
  • 🚫 Turn off the live wallpaper, they heavily load the processor and consume battery power.
  • πŸ“‰ Remove unnecessary widgets from the desktop, especially those that are updated in real time (weather, news).

It's also worth checking the screen settings. If you have "High Brightness" enabled or the automatic adjustment is not working properly, it can cause overheating and subsequent performance decline. Adjust the brightness manually to the light conditions.

Application and Autoboot Management

Many apps run automatically with a smartphone and continue to hang in the background, consuming resources. MIUI has a rigid permission management system that needs to be configured correctly. Autoboot control is a key point of optimization.

Go to the Security settings β†’ Permissions β†’ Autorun. Here you will see a list of all the programs that start when you turn on your phone. Leave only messengers (for notifications) and antivirus on.

Type of applicationRecommendationImpact on RAM
Messengers (WhatsApp, Telegram)Leave in autoload.Average.
Social media (VK, Instagram)Disable autostartHigh.
GamesStrictly shut downHigh.
Xiaomi ServicesDon't turn it off.Low.

Also, use the application freeze function or limit background activity for rarely used programs. Each application settings have an activity control option where you can select the no background mode, which will cause the application to close completely after you leave it.

πŸ’‘

Use Game Turbo mode for more than just games, add heavy apps that you use all the time, and prioritize the processor resources for those applications.

Deleting the system applications (bloatware) is a riskier step. Although Redmi 9 has a lot of pre-installed software, removing some components can disrupt the system, it is better to simply disable unnecessary services from Google or Xiaomi in the application settings, if this is possible.

System update and resetting

Often performance issues are caused by software errors in the current firmware version. Xiaomi regularly releases security and optimization updates. Check for updates in the Settings menu β†’ About the phone.

However, if the phone hasn't been updated for a long time or, on the contrary, it has become worse after the upgrade, you may need a complete reset. Data formatting removes all the accumulated registry errors and file conflicts over the years of use, this is a radical, but the most effective method.

Before you reset, make sure to back up your important data to the Mi Cloud or your computer, and the process will completely clear your internal memory, bringing your phone back out of the box.

Once reset, you don't have to restore all the applications from the backup at once, set the minimum and test the work, and it often turns out that one particular application caused the entire system to conflict.

⚠️ Warning: Before resetting, make sure the battery is at least 60% and the phone is connected to a stable Wi-Fi network.

Additional technical recommendations

There are more advanced methods available to power users, such as disabling debugging by USB, if it has been previously included, or the use of ADB-commands to remove system debris, but for most users, the steps above are enough.

Also worth paying attention to the temperature of the case. If the Redmi 9 is constantly hot, it may have dried the heat paste or clogged the speaker with dust, in such cases, software optimization will only give a temporary effect, and you will need a physical cleaning.

Using lightweight versions of apps (Lite) is a great strategy for budget devices. Facebook Lite, Skype Lite versions or using web versions of social networks through the browser significantly reduces the load on the processor and memory.

πŸ’‘

The comprehensive approach, which includes memory cleaning, disabling animations and autoboot control, can extend the comfortable life of the Redmi 9 for another 1-2 years without replacing the device.

Don't ignore the state of the network. Slow internet can create the illusion of a slowing phone, where pages or content in apps just load for a long time. Check the connection speed and reset the network settings if necessary.

Comparison of optimization methods

If your phone starts to brake suddenly, try cleaning. If the degradation has been gradual over the years, only a complete reset will likely help.

Questions and Answers (FAQ)

Why did Redmi 9 start to slow down after the MIUI update?
After a major update, the system indexes files and optimizes applications in the background, which can take anywhere from a few hours to 2-3 days, during which time the phone can warm and run slower, give the device time by connecting it to charging and Wi-Fi overnight.
Is it safe to use third-party accelerators like Clean Master?
Xiaomi does not recommend using such programs; the built-in MIUI system itself effectively manages memory. Third-party accelerators often impose advertising, collect user data and create additional load on the processor, working in the background.
Will memory expansion help speed up games?
Memory Extension is part of RAM (Flash) memory. Since the speed of the built-in drive is lower than that of real RAM, the gains in games will be minimal or imperceptible, which will help keep more applications open in the background rather than increase FPS.
Can I overclock the processor on Redmi 9?
Theoretically, this is possible through the acquisition of Root rights and the use of special cores, but for the Redmi 9 model with a Helio G80 processor, this does not make practical sense. Overclocking will lead to critical overheating and rapid battery degradation, and the performance gains will be offset by trottling.
