How to fix the application in the memory Xiaomi Redmi 9T: From standard methods to hidden chips MIUI

You’ve noticed how your favorite app is on Xiaomi Redmi. 9T So suddenly it flies out of memory, causing you to waste time restarting? This is a typical problem with 6 to 8 GB of RAM, where the system aggressively clears the background processes (RAM). This approach not only speeds up the switching between tasks, but also prevents data loss in instant messengers or games.

In this article, we will understand 5 Proven methods – from built-in functions MIUI to manual settings through ADB. Important: Not all methods are equally effective, and some require unlocking the bootloader or superuser rights.We will be honest about the risks and limitations of each option so you can choose the best one for your Redmi model. 9T (version NFC and Global/China ROM).

Let us dwell in detail on:

  • πŸ”§ The built-in "Applications Attachment" in MIUI (work-in)
  • πŸ“± Hidden Developer Settings for Memory Management
  • πŸ–₯️ ADB-commands for forced fixation of processes
  • πŸ› οΈ Magisk modules for advanced users
  • ⚠️ Possible consequences: overheating, fast battery discharge, lag

⚠️ Note: Attach more than 3-4 applications simultaneously on Redmi 9T Snapdragon 662 processor may cause system slowdown due to lack of free-of-charge RAM. It is optimal to fix only critical services (for example, Telegram or navigator).

  3. Swipe down the app icon and a menu will appear.
  4. Select the item "Secure" (icon with a pin).

After that, the application will remain in memory even when cleaning. RAM There are limitations to the method, however, through the Clear Menu button:

  • πŸ”„ Works only until the device is restarted - after turning on the fixation will have to be repeated.
  • πŸ“΅ Not all system applications (such as Mi Video) support anchoring.
  • πŸ”‹ Can increase battery consumption by 5-10% when fixing heavy applications (games, social networks).

Open the multitasking menu|Check the version. MIUI (less than 12.5)|Make sure the application is not system-based|Clean up RAM before fixation-->

To verify the success of the consolidation:

  1. Launch the app.
  2. Get back on the main screen.
  3. Open Settings β†’ About the phone β†’ Memory status.
  4. Check if the app is still on the Active list after 5-10 minutes of inactivity.

⚠️ Note: Some of the Redmi firmware 9T With custom cores, the fix function may not be available. MIUI Up to the latest stable version via Settings β†’ Updating the system.

2 Developer settings: limiting processes in the background

If the standard method didn't work, you can manually limit the number of background processes so that the system can lessen the number of applications it needs to unload, and this requires activation of the developer mode.

Steps to set up:

  1. Activate Developer Mode: Go to Settings β†’ About the phone, tap 7 times on the version MIUI. Enter your Xiaomi account password if required.

How do you know? UID applications?
1. Connect your phone to the PC and open it. ADB. 2. Enter the command: adb shell dumpsys package [name packet] | find "userId" (for Windows) or adb shell dumpsys package] | grep userId (for example, for macOS/Linux). 3. In the conclusion, find the line of the userId=10123 β€” That's it. UID.

To cancel the fixation, execute the command:

adb shell am broadcast -a android.intent.action.RUN --ez lock false --ei uid [UID_ of the appendices]

4.Magisk modules for permanent fixation

If you're ready to unlock the bootloader and install Magisk, you can use dedicated memory management modules, which give you maximum control over the processes, but requires technical skills.

Popular modules for Redmi 9T:

  • πŸ”’ RAM Optimizer – allows you to manually select applications for fixation.
  • πŸš€ Swift Installer – optimizes the use of RAM and cache.
  • πŸ›‘οΈ App Systemizer – converts user applications into system applications (protects from unloading).

Installation instructions:

  1. Unlock the bootloader through the Mi Unlock Tool (the official Xiaomi tool).
  2. Install custom recovery (TWRP or OrangeFox).
  3. Sweep through Magisk (the latest version from GitHub).
  4. Download the module (for example, RAM Optimizer and install it through Magisk Manager.

Magisk modules give maximum control over the RAM, But they require unlocking the bootloader and they pose a risk to system stability.

5. Alternative methods: Greenify and Automatic Optimization

If previous methods seem complicated, you can use applications to manage background processes, one of the most effective is Greenify (requires root for full functionality).

How to set up Greenify on Redmi 9T:

  1. Download Greenify from Google Play.
  2. Provide root access (if any) or activate special features to work without root.
  3. Add apps to the list of β€œEutrifications” (e.g. Facebook, TikTok).
  4. Enable the option Aggressive Euthanization for critical applications.
  5. Activate automatic hibernation in the settings.

The benefits of Greenify:

  • πŸ”‹ Reduces battery consumption by 10-15%.
  • πŸš€ Accelerates the system by cleaning up unnecessary processes.
  • πŸ›‘οΈ Works without root, but with limitations (for example, can not fix system applications).

You can use MacroDroid or Tasker to automate the process:

  • πŸ€– MacroDroid: Create a macro to run Greenify when you lock the screen.
  • βš™οΈ Tasker: Set up a cleaning task RAM every 2 hours (Time profile) β†’ Every 2H).

FAQ: Frequent questions about attaching applications to RAM

❓ Can system applications be fixed (for example, Settings or Phone)?
No, system applications. MIUI This will require Magisk and the App Systemizer module, but this can lead to unstable operation of the phone.
❓ Why do fixed applications disappear from memory after reboot?
It's a feature. MIUI β€” When you restart, the system resets all the temporary fixations. ADB-flag-bearing --persistent or Magisk modules with autoboot.
❓ How to check how much memory is occupied by the fixed application?
Go to Settings. β†’ The phone. β†’ Status of memory β†’ Memory usage: This shows detailed statistics for each process. AIDA64 DevCheck.
❓ Will the fixing work on custom firmware (for example, Pixel Experience)?
Yeah, but the mechanism might be different. AOSP (For example, LineageOS or Pixel Experience, use the built-in Lock app in memory in the Magisk developer settings or modules.
❓ Can I play the game (e.g. Genshin Impact or PUBG)?
Technically yes, but it's highly discouraged. Games take up to 1-2GB RAM, And fixing them will lead to system lags. Instead, use Game Turbo in the game. MIUI to optimize productivity.
