The modern rhythm of life often requires the separation of digital space into personal and work, but carrying two smartphones is not always convenient. The owner of the flagship Xiaomi Mi 9T can easily solve this problem using the built-in capabilities of the MIUI shell, which allows you to run copies of popular programs in parallel with the main one.
The process of creating duplicates on this device is as simple as possible for developers and does not require root rights or complex system flashing. Unlike many other Android smartphones, where you have to download dubious software, everything works at the kernel level, ensuring stability and energy efficiency. Let's figure out how to activate this feature correctly and what to do if the desired application is not on the list of supported.
Built-in dual application function in MIUI
The main tool for solving this problem is a system utility called Double Applications, which is hidden in the depths of the settings menu and is designed to create an isolated container where a copy of the program works independently of the original, which means that you can receive notifications even when the main application is closed or running in the background with restrictions.
To activate the function, follow the Settings → Applications → Dual Applications path. The list that opens will display all programs that support cloning on your Xiaomi Mi 9T. These are usually social networks, instant messengers and some gaming platforms that require authorization.
Once the switch is turned on next to the name, a new icon with a yellow badge in the second corner will appear on the desktop, a visual marker that helps you not to confuse the main account with an additional one, and the system automatically synchronizes contacts and permissions for a new copy, creating a full second environment.
⚠️ Note: When you delete the main application, the clone will also be automatically deleted by the system, so you should not delete the original if you want to save the second account.
💡
If you delete the main application by accident, the clone will disappear without the ability to restore data, so always keep the original installed.
Step-by-step instructions for activating cloning
To ensure that the process is successful and data is not lost, it is recommended to adhere to a certain algorithm of actions, especially for users who have previously used third-party launchers or modified system files, the standard procedure takes no more than a minute and does not require restarting the device.
First, open the standard settings menu of your Xiaomi Mi 9T and find the section responsible for managing installed software. Inside you will need to find a subsection called “Dual Apps.” If the search for settings does not work, make sure that your version of MIUI is updated to the current one, since in older builds the menu could be located differently.
In the list that opens, you'll see switches opposite compatible programs. Click on the switch to activate the clone. The system can request confirmation or show you a brief statement of how the new copy will work. Once activated, the icon will appear on the desktop, and you can launch it to log into the second account.
☑️ Algorithm for incorporating cloning
It’s important to understand that each copy consumes additional RAM resources. On the Xiaomi Mi 9T with its 6 or 8GB of RAM, this won’t be a problem for most scenarios, but with heavy gaming and a lot of background processes running at the same time, the system can begin to aggressively clear the memory.
List of supported applications and limitations
Not all software can be cloned by standard means. The list of software supported is formed by the developers of MIUI and depends on the technical features of each application, most often on the list are popular social networks, banks and delivery services, where the separation of accounts is most popular.
Below is a table with examples of apps that are guaranteed to work in cloning mode on the Xiaomi Mi 9T, and their support status:
| Annex | Type | Status of cloning | Features |
|---|---|---|---|
| messenger | Full support | Push notifications are working | |
| Telegram | messenger | Full support | Not required, there is a built-in function |
| Social network | Full support | Rare notification failures are possible | |
| VKontakte | Social network | Full support | Stable work |
| Sberbank Online | Finance. | Partial support | May require re-binding |
It is worth noting that some banking applications may block the work in cloned mode for security reasons, in which case the system may warn about potential risks or simply not show the application in the list available for cloning.
Use of the Second Space Mode
If built-in cloning isn't enough or the app is not on the supported list, Second Space comes to the rescue, a deeper level of isolation that creates a virtual second user profile with its own set of apps, passwords and settings.
Unlike simple cloning, Second Space requires separate authorization to Mi Account or setting up a new pin code to log in.Switching between the main and second space takes place through a notification curtain or a special shortcut on the lock screen, which simulates using two different phones.
To activate, go to Settings → Second Space and follow the instructions of the customization wizard, you can move some applications from the main profile or install them again, which is ideal for the complete separation of work and personal life, when you need to hide the presence of certain programs from prying eyes.
⚠️ Switching between spaces takes longer and consumes the battery faster than using conventional dual applications, as the two environments actually work.
Alternative methods through third-party utilities
When Xiaomi Mi System Tools 9T If you don't do it, or you want to clone an application that's not officially supported, you're turning to third-party solutions, 2Accounts Multiple Accounts, or Multiple Accounts, create a virtual environment within itself to run copies of the account.
Installing these gates requires permissions, requesting access to almost all of the phone’s functions, which can raise concerns about data privacy, but for insecure accounts (such as gaming or test accounts), this is a viable option.
When using third-party cloners, it is worth considering that they work as a “shell” inside the shell, which puts additional strain on the Snapdragon 730 processor. This can lead to faster battery discharge and heating of the case during prolonged operation.
Why are some apps not cloned?
Optimization of the work of cloned applications
To ensure that dual applications are stable and do not “fly” in the background, you need to properly configure power management. MIUI is known for its aggressive policy of closing background processes to save charge, which can interrupt the work of messengers in the second profile.
It's recommended to go to the battery settings, find the cloned app, and set the "No Limits" mode, and it's also useful to pin the app to the running task menu by pulling the card down so that the system doesn't clear its memory when it auto-clears.
Periodically check for updates to the apps themselves via Google Play or GetApps. Developers often optimize code for multi-window and in-screen devices like the Xiaomi Mi 9T, eliminating interface display bugs.
💡
Setting up the power saving mode for each clone is a must-do step to ensure real-time notifications are received.
