How to remove the problems Xiaomi Redmi 9: advertising, lags and unnecessary applications

Owners of budget smartphones often face intrusive advertising and pre-installed garbage. Xiaomi Redmi 9 model was no exception, offering rich functionality for an affordable price, but requiring competent customization. Immediately after purchase, the device can seem overloaded with unnecessary services that consume resources and annoy users.

Fortunately, MIUI provides a wide range of customization options, so you can turn off most ad units, remove unnecessary Chinese apps, and optimize your CPU, making your gadget a fast, clean tool for everyday tasks.

In this guide, we will look at proven methods of cleaning the system, we will look at both standard tools and more advanced ways to remove system debris.

Disabling system advertising in MIUI

The first step to comfortable use is blocking embedded advertising. Xiaomi has introduced a special service called msa (MIUI System Ads), which is responsible for displaying banners in system applications, and turning it off is a priority for any user.

To start, you need to go to your account settings. Open Settings → Passwords and security → Access to personal data. In the list that opens, find msa and turn off the access slider. The system will ask you to wait 10 seconds, after which you will require confirmation of action.

⚠️ Note: If you failed to turn off the service the first time, repeat the procedure 3-4 Servers can be overloaded and the timer can reset, but persistence usually leads to success.

After a successful shutdown, msa is recommended to deny access to data for other suspicious services such as Mi Credit or Mi Video if you do not use them, which will significantly reduce the number of pop-ups and background activity.

Removal of pre-installed garbage (Bloatware)

The standard set of applications often includes games, markets and services that are not needed by the user in the CIS. It is not always possible to remove them in the usual way through the desktop, since many of them have the status of system.

For deep cleaning, you can use the built-in application hide-and-seek function or third-party utilities, but the most effective method is to use ADB (Android Debug Bridge), which allows you to remove even those packets that are hidden from the average user.

• 📱 Enable Developer Mode by clicking 7 times on the build number in the About Phone section.
• 🔌 Activate debugging on USB on the Developer Menu.
• 💻 Connect your smartphone to your PC and use the command to remove packets.

The list of safe packets for removal includes com.miui.videoplayer, com.miui.player and various marketplaces like com.xiaomi.mipicks. Be careful: removing system components like com.android.phone can lead to loss of communication.

Optimizing energy consumption and background processes

The battery in Redmi 9 has a capacity of 5020 mAh, but background processes can negate this advantage.MIUI aggressively manages memory, but sometimes manual intervention is required to extend autonomy.

Go to Battery and Performance and select Balanced Mode, and in advanced settings, you can limit background activity for specific applications, which is especially useful for social networks that are constantly updating the feed.

It is also worth disabling the function Expansion of memory, if it is available in your version of firmware and you do not experience an acute lack of RAM. Virtual memory uses the drive, which can reduce the overall response rate of the system on older models.

💡

Use Do Not Disturb mode at night so that apps don’t wake up the screen and consume charge in the background.

Customize the interface and remove unnecessary elements

Visual noise on the screen is distracting and creates a cluttered feeling. The MIUI desktop allows you to flexibly customize widgets and tapes. First, remove the widget tape on the left (Google Discover) if you don't need it.

To do this, pinch your two fingers on your desktop, go to the settings and turn off the widget tape, and you can also change the icon grid to make them look larger or smaller.

Another important element is the Tools folder, which has all the system utilities in it by default, so you can take the apps you want to get to your desktop and delete or hide the folder, which will speed up access to the functions you use.

• 🧹 Use the "Cleaning" widget for quick cache cleaning.
• 🎨 Set a dark topic for AMOLED-screens (although in Redmi 9) IPS, It saves your eyes).
• 📉 Reduce the font size to display more content.

⚠️ Warning: Do not remove the system launcher without installing an alternative.This can lead to a freeze in the interface and the need to reset settings.

Accelerating work and animation

The Helio G80 processor in Redmi 9 handles everyday tasks, but heavy MIUI animations can create the illusion of slow work.

In the Developer menu, find the Drawing section, and there are three parameters: window animation scale, transition animation scale, and animation duration scale. Set 0.5x or even Off for instant response.

You can also activate the GPU Acceleration option (if available in your Android version), which will force the system to use the GPU more actively to render the interface, unloading the main cores.

💡

Reducing the scale of animations to 0.5x visually speeds up the smartphone by 30-40% without losing performance in games.

Reset and return to factory settings

If software methods have not helped to remove deep bugs or lags, the radical method remains: a complete reset, which will return the device to the state of “out of the box” by removing all user data and settings.

Before the procedure, make sure to back up. Use Mi Cloud or local save in Advanced Settings menu → Reset settings. Select Erase all data and confirm the action.

It's gonna take about 10-15 When you reboot, you get a clean system, and the recommendation is not to restore all the applications from the backup, but to install them again, so as not to bring back old conflicts and debris.
