Xiaomi Redmi Note 9 is a popular smartphone with powerful hardware, but even it sometimes encounters hanging apps: some programs “hang” due to errors, others continue to work in the background and eat the battery, others block the screen altogether. In this article, we will discuss all the ways to stop the application from basic to advanced, including forced closure through ADB and hidden MIUI functions.
It's important to understand that simply swiping an application from the multitasking menu doesn't always stop it completely. Many services (such as instant messengers or games) continue to run in the background, consuming resources, and we'll show you how to completely shut down the program, including system processes that cannot be closed down by standard methods.
The instructions are valid for all Redmi Note 9 modifications (including Note 9 Pro, Note 9S, Note 9T) based on MIUI 12-14 and Android 10-13. If your smartphone runs on an older version of the firmware, some menu items may differ - we will warn you about this separately.
1. Standard Closing Through Multitasking
The easiest way is to use the recent app menu, which is suitable for most user programs (social networks, games, browsers), but does not guarantee a complete stop — some processes may remain active in the background.
How to do this:
- 📱 Click the Multitasking button (square in the bottom navigation bar) or swipe up from the bottom edge of the screen and hold your finger for 1 second.
- 🔍 Find the desired application in the list and swipe it up (or sideways, depending on the version). MIUI).
- ⚡ To close all applications, immediately click on the “Close Everything” icon (cross or trash can).
⚠️ Note: This method does not work for system applications (e.g. com.miui.home) and services with administrator rights.
2. Forced stop through Android settings
If the application is frozen or does not close through multitasking, use the built-in Stop feature in the settings. This is guaranteed to interrupt all the processes of the program, but can reset unsaved data (for example, drafts in messengers).
Step-by-step:
- Open Settings → Applications → Application Management.
- Find the app you want (use the search at the top if there are many).
- Then, tap it and choose to stop (or force it).
- Confirm the action in the window that appears.
🔹 What if the Stop button is inactive? It means that the application is system or has administrator rights:
- 🔐 Go to Settings. → Passwords and security → Administrator rights and disable permissions for this application.
- 🛠️ System programs (such as Google Play Services) may need to be disabled via ADB (let's take it down).
☑️ Preparations for forced suspension
3. Stop through "Battery and Performance"
MIUI has a hidden tool for controlling background processes, the Battery and Performance partition, where you can not only stop the application, but also limit its activity in the future.
How it works:
- Go to Settings → Battery and Performance → Battery Management.
- Select the App tab and find the desired program.
- Slip on it and choose to limit background activity or stop.
| Option. | What's he doing? | Suitable for |
|---|---|---|
| Stop it. | Forcedly closes all application processes | Hanging programs, games |
| Limit background activity | Blocks auto-start and work in the background | Social networks, messengers that eat the battery |
| Allow auto-start | Start/disable the start at system start | System applications that are not needed |
⚠️ Attention: Restricting background activity for system applications (such as Mi Cloud or Google Play Services) can cause smartphone malfunctions.
4.Using the "Distractless" (DND) mode
If the app is not only hanging in the background, but also constantly sending notifications (for example, banner ads), it can be blocked through the Do Not Disturb mode.
How to turn on:
- 🔔 Go to Settings. → Notifications and status bar → Don't disturb.
- 📵 Select the Applications and add the desired program to the blacklist.
- 🔕 Activate Do Not Disturb via the notification panel.
🔹 Pros of the method: does not require root-rights, works for all applications, including system.
🔸 Cons: Does not stop background processes, only blocks notifications.
💡
If the app continues to send notifications even in DND mode, check its rights under Settings → Notifications → Special Access. Some programs (such as Facebook) bypass standard restrictions.
5. Advanced methods: ADB and USB debugging
For power users, there is a way to stop any application, including system ones, via Android Debug Bridge (ADB).This requires connecting the smartphone to the computer, but gives you complete control.
Step-by-step:
- Turn on Developer Mode: Go to Settings → About Phone. Tap 7 times on MIUI Version until the notification “You’ve become a developer” appears.
USB debugging
Settings → Additional → For Developers
ADB-driver
adb shell am force-stop com.example.app🔹 How to find out the name of the application package?
- 📦 Use the adb shell pm list packages command | grep "name" (e.g. grep "facebook").
- 🔍 Or install the App Inspector app from Google Play.
⚠️ Warning: Stopping system applications (e.g. com.android.phone) can cause communication loss or smartphone reboot. Use this method only if you understand the risks.

Extreme measures: reset and discharge
If the app has blocked the screen or the smartphone does not respond to touch, radical methods remain:
- 🔄 Forced reboot: Press the Power button for 10-15 seconds until the device shuts down and starts to boot again, which will stop all the processes, but will not delete the data.
- ⚙️ Safe Mode: Press the Power button, then hold your finger to Turn off until you have a suggestion to go to Safe Mode. It only runs system applications.
- 🗑️ Reset to factory settings: last resort if the smartphone is completely locked. Use Settings → The phone. → Resetting settings or a combination of power buttons + Volume up when loading.
🔹 How to avoid data loss? Regularly back up through Settings → Additionally. → Backup and reset or use Mi Cloud.
💡
Forced reboot is the most reliable way to stop a hanging application, but it doesn't solve the problem forever. If the program is constantly hanging, delete it or update it.
