Modern smartphones, including the popular Xiaomi Redmi 9, have become an integral part of our lives, providing instant access to information. However, the constant stream of messages, notifications from games and system services can turn the device from an assistant into a source of irritation, especially when the phone begins to vibrate or make sounds at inappropriate moments, such as during a meeting or rest.
Redmi 9 owners often face the need to fine-tune MIUI, which is set to maximize user awareness by default.This means that a lot of pre-installed apps and services try to grab your attention every minute. Fortunately, Xiaomi’s shell offers flexible tools to manage these processes, allowing you to fully control the sound and pop-ups.
In this article, we will take a look at all the ways to disable notifications, from fast locking a particular application to deep system setup that will make your phone really quiet, learn how to distinguish between system sounds and app alerts, and learn about hidden features that will help save battery power and nerve cells.
Basic sound and vibration settings through the menu
The first step to silence is to properly configure the basic sound profiles. In Xiaomi Redmi 9, basic parameters are controlled in a separate menu where you can customize the behavior of the device in various situations. Don’t ignore this section, since this is where the switches responsible for system sounds, which are often confused with messenger notifications, are hidden.
To start, you need to go to Settings → Sound and Vibration, and here you will see sliders for adjusting the volume of the call, media, alarm clock and, most importantly, notifications. Make sure that the notification slider is moved to the far left position if you want complete silence, or set it to a comfortable level. Also worth paying attention to the item "Locking Sound" and "Touch Sound", which can create unnecessary noise when using the interface.
Not only does Do Not Disturb Mode feature deserve special attention. Unlike a simple turn off of the sound, this mode allows you to create a schedule where the phone will ignore incoming calls and messages, except those that are marked as important. On Redmi 9, this mode can be activated manually or set up automatically on at night, which is especially useful for quality sleep.
⚠️ Note: When you turn on Do Not Disturb mode, make sure that no contacts are added in the exceptions that you really want to miss unless your goal is complete isolation.
Remember that the physical sound switch (if you have one in your modification or through the program buttons) changes the profile at once for all types of sounds, unless otherwise configured. Therefore, for spot work, it is better to use the software settings described above, rather than simply turning down the overall volume with buttons on the case.
Managing Notifications for Specific Applications
The most common source of noise is social media and instant messengers, and MIUI has a powerful tool to manage the rights of each app installed separately, allowing you to leave audio notifications for WhatsApp, for example, but completely disable them for games or news aggregators.
To access these settings, go to Settings → Notifications and Status bar → Notification Management. You will see a list of all apps that have permission to display information on the screen. Choose the desired application, such as Instagram or Telegram. Inside you will see the Allow Notifications switch, which completely blocks any signals from the program.
However, a more flexible approach is to configure notification categories within the app, and by clicking on the app name in the list, you can see the details: “Incoming messages”, “Calls”, “Advertising” or “Shipping Status”.
- 🔇 Sound: Choose a melody or put “No sound».
- 📳 Vibration: Turn on or off tactile response.
- 🔔 Pop-up notification: Allow or disallow windows over other apps.
- 📉 Importance: Change priority, which affects the display in the status bar.
This approach allows you to keep the app functional by removing only annoyances, such as leaving the vibration for private messages, but removing the sound for news channels, and this is especially true for users who use Redmi 9 as their primary working tool.
☑️ Checking the application settings
Disabling system notifications and advertising in MIUI
The MIUI shell installed on Xiaomi Redmi 9 is known for its built-in services that can generate its own notifications, which can be recommendations from the Security app, offers from Explorer, or news from Mi Browser. Often users do not know how to turn off these system pop-ups, believing them to be a virus or error.
To turn off ads and recommendations in system applications, you need to go to the settings of each of them separately. For example, in the Security app, click on the gear in the upper right corner and find the item "Receive recommendations." Similar settings are present in Downloads, Music and Topics. Disabling these options will significantly clear the notification curtain from information noise.
You should also check your Mi Account settings. Sometimes Xiaomi services may send notifications about new features or promotions. To disable them, go to Settings → Mi Account → Account settings and uncheck the items associated with marketing mailings. This action will not affect the operation of cloud services, but remove unnecessary reminders.
⚠️ Warning: Do not disable system services called System Updates or Framework Services unless you are sure of their purpose.
Another source of sound is the interface. Screen lock, charging and keyboard touching sounds can be turned off from the Settings menu → Sound and vibration → Additional. This also includes the “Charge Connection Sound” setting, which often surprises users with a sudden melodic signal.
Hidden system sounds
Use of working hours and timetables
Xiaomi Redmi 9 offers advanced automation tools through Modes. These are not just audio profiles, but entire phone usage scenarios. You can create a Work mode that turns off all notifications except calls from favorite contacts, and Home mode, where all sounds are allowed.
To create your own mode, go to Settings → Special Features → Modes (the path may vary slightly in different versions of MIUI). Here you can adjust the rules: if it is from 23:00 to 07:00, then turn on Do Not Disturb mode and turn down the brightness. This eliminates the need to adjust the phone every evening.
Of particular interest is the Notifications in Your Pocket feature, which prevents the screen from turning on and sounds when the phone is in your pocket or bag. If this feature is not working properly and the phone continues to make noise in your pocket, try calibrating the proximity sensor or temporarily disabling this option in the lock screen settings.
| Type of regime | What's blocking | What's missing | Indication |
|---|---|---|---|
| Normal. | Nothing. | All right. | Sound + Vibration + Screen |
| No sound. | Sounds. | Vibration and Screen | Just vibration. |
| Don't disturb. | Sound and vibration | Only selected (by setting) | Screen only (optional) |
| Just an alarm clock. | All except the alarm clock. | Alarm clock | No. |
Using schedules to switch modes is the most effective way to maintain a digital hygiene balance.You don't have to remember to switch your phone to silent mode before bedtime or meeting, Redmi 9 will do it automatically.
💡
Set up automatic Do Not Disturb mode from 23:00 to 07:00 to ensure that morning news or app updates don’t wake you up ahead of time.
Setting up the LED indicator and lock screen
Even if the sound is turned off, a flashing LED or a lighting screen can be uncomfortable, especially at night. In the Xiaomi Redmi 9, the LED indicator can signal missed calls, messages and low battery power. You can control this through the Settings menu → Lock screen.
Here's the light display, which you can turn off completely, or you can set the blinking to specific events only, for example, it's useful to leave the blinking at low battery power, but remove it for social media messages so you don't get distracted by every new email.
You should also pay attention to the Raise to Wake feature, which means that if the phone is on the table and you touch the surface, the screen can light up, showing notifications, and turning it off in the same Lock Screen menu will save battery power and eliminate unnecessary visual stimuli.
For users who prefer minimalism, it is possible to disable the display of notification content on a locked screen, in which case you will see only the app icon and the text of the New Notice, which preserves privacy and reduces visual noise.
⚠️ Warning: A complete lighting shutdown may cause you to miss an important call if the phone is lying down screen and in silent mode.
Advanced settings for advanced users
For those who want to gain absolute control over the Xiaomi Redmi 9, there are advanced settings available through the developer menu or special commands. However, be careful: changing system settings can affect the stability of the device.
One useful feature is Notification Monitoring. In some versions of MIUI, you can see which application wakes up the screen most often or uses the network in the background. Go to Settings → Battery and Performance → Charge consumption to analyze application activity. If you see an application that you rarely use but is constantly active, you should limit its background activity.
You can also use it. ADB-commands to clean the system more deeply from preset noise, but that requires a connection to a computer. For most users, the standard tools described above are sufficient. If you choose to use third-party apps to manage notifications, make sure they have the necessary permissions and are not the source of advertising.
It is important to check system updates periodically. Xiaomi engineers are constantly improving MIUI algorithms, and new versions may come with more convenient tools to manage notifications or fix bugs that cause false positives.

Regularly reviewing installed apps and their notification rights is the best way to prevent information noise on your smartphone.
