Xiaomi’s current smartphones, which run on the shells of MIUI and the new HyperOS, offer users tools that are often undervalued, one of which is to create an isolated environment inside a single device, not just a folder, but a full-fledged clone of the system that allows you to hold two different accounts, apps and photo galleries at the same time.
Many phone owners face the need to separate their personal and work lives, but they don't want to carry two gadgets with them. This is where Second Space comes on the scene, which creates a digital boundary that is inaccessible to prying eyes without a special password or fingerprint.
In this article, we will discuss in detail how this technology works, why it can be useful for you, and what real users think about it after long-term use, and we will also touch on the technical nuances that will help avoid common customization errors.
What is the Second Space and How Does It Work Technically?
At its core, this feature is an analogue of a guest profile, but with advanced functionality. When you activate the mode, the system creates a separate file structure and database. Applications installed in the main profile do not see the data of the second, and vice versa.
The data isolation here is implemented at the file system level, which means that if you download a virus in one profile, the probability of it entering another is minimal, although the underlying system will remain common.
Technically, it requires resources. RAM is shared between two active environments if they are running, which can affect the performance of budget models. However, for modern Snapdragon and MediaTek processors, this is a standard operation, causing no noticeable delays.

Use scenarios: who and why it is necessary
The most obvious application is the separation of work and leisure, you can install corporate messengers in the Second Space, and leave personal ones mostly, and at the end of the workday, you just log off the profile, and notifications from the boss no longer bother you.
The second popular scenario is increased security, where you can store bank apps, photo documents and confidential correspondence in an additional profile, and even if the phone falls into the wrong hands and is unlocked, the attacker will only see a clean main screen.
- 🔒 Hidden Access: The ability to assign a different fingerprint to enter the main and hidden profiles.
- 🎮 Children's Mode: Install games and YouTube Kids in second space with limited time and purchases.
- 📱 Testing: Safe installation of doubtful APK-files or beta versions of programs without risk to the main system.
And remember, you can have two accounts in one app, and while the full-time App Clone does that, Second Space allows you to clone any program, even those that aren't supported by a standard cloner.
Step-by-step: how to create and configure a profile
The process of activating the feature is as simple as possible by the developers of Xiaomi. You do not need superuser rights or a connection to a computer. Everything is done through the standard settings menu, which is available on most current models.
You first need to go to Settings. Then scroll down and find Second Space. In some versions of MIUI, it may be inside the Advanced Settings or Special Features menu, but most often it is placed in a separate category.
☑️ Profile-building algorithm
Once you press the power button, the system will suggest you choose a switching method, which can be a separate shortcut on the desktop, a combination of buttons, or, most conveniently, a fingerprint, and by assigning your left hand to the main profile and your right hand to the hidden one, you can instantly change the environment when you unlock the screen.
⚠️ Note: When creating a new space, the system may request permission to access contacts and a gallery for possible data transfer. If you plan to be completely isolated, refuse to import so as not to leave digital traces.
Feature comparison: Second space vs. App clone
Many users confuse the two functions as identical, but there is a fundamental difference in architecture and purpose between them, and understanding these differences will help you choose the right tool for your tasks.
The app clone works at the level of a single user profile. It creates a copy of a specific user profile. APK-It's a lightweight solution that consumes minimal resources, but doesn't provide complete isolation.
| Characteristics | Second space | Apps clone |
|---|---|---|
| Level of isolation | Complete (separate OS profile) | Partial (within one profile) |
| RAM consumption | High. | Low. |
| Number of copies | One extra space | Multiple cloning (depending on the model) |
| Secrecy | High (password/finger required) | Low (Icons are visible on the menu) |
If you want to just run a second WhatsApp or Telegram, you better use a full-time cloner, but if you want to hide the fact that certain programs are being used or separate working documents from personal ones, Second Space is unparalleled.
💡
The main difference: the second space is a separate operating environment with its own settings, and the application clone is only a shortcut copy within the current system.
Problems, bugs and reviews of real users
While useful, the feature is not without its drawbacks: Analyzing the forums and feedback from Xiaomi owners for 2026-2026, we can highlight a number of typical problems that users face.
One of the biggest complaints is battery consumption: since background processes can continue in both profiles, battery life is reduced by 10-15%, and some banking applications may be blocked if a second space is running (detected), considering this as a sign of emulator or hacking.
Users also note the difficulty of notifying, and sometimes messages in the second profile don't arrive while you're mostly in the background, and vice versa, due to the aggressive energy savings of MIUI, which "sleeps" the background profile.
- 📉 Performance: On models with 4GB of RAM or less, the phone may start to slow down when switching.
- 🔔 Notifications: Calls and messages can be duplicated or lost.
- 💾 Memory: Two sets of cache and data take up a significant amount of internal memory.
⚠️ Note: When you delete the Second Space, all the data inside it (photos, contacts, files) will be permanently destroyed.
Removal and Control: How to Get Out of the Second Space
If the function is no longer relevant, it can be easily deactivated, and you need to go to the settings of the Second Space itself (usually through a shortcut or swipe in the lock menu) and select the delete point.
The system will require the password of the primary owner to be verified, an important security measure to prevent accidental or malicious deletion of data, which takes anywhere from seconds to minutes, depending on the amount of information being deleted.
Settings → Second Space → Menu (three dots) → Delete Second SpaceAfter deleting the free space on the drive will be available for use, it is recommended that after this procedure, the device is restarted so that the system correctly redistributes resources and clears temporary files.
💡
Expert advice: Before deleting your profile, use the Move Files feature to move important photos and documents to the main space, which will take a couple of clicks and save your data.
