Why you need a second space in Xiaomi Redmi: the complete guide

Xiaomi and Redmi smartphone owners often face the need to separate personal and work information, but not everyone knows about the built-in feature called Second Space, which allows you to create a completely isolated environment inside the same device, which radically changes the way you manage data, you get virtually two different smartphones in the same case, each with its own set of applications, files and account settings.

Using this technology solves a variety of problems, from the clutter of the desktop to ensuring the privacy of correspondence. Spaces work independently of each other, which means that notifications from one profile will not bother you in another, and running processes will not conflict, this is especially true for those who are used to keeping work chats and personal social networks in strict separation.

Many users mistakenly believe that it is enough to simply use the Guest mode or the App Cloning function to separate accounts, but the second space offers a much deeper level of isolation. In this review, we will take a closer look at the architecture of this feature, its advantages over third-party counterparts, and walk through the activation and fine-tuning process Step-by-step.

The concept of isolation: how it works technically

Technically, the Second Space in the MIUI or HyperOS shell is implemented at the Android operating system level using multi-user profile mechanisms. When you activate this feature, the system creates a new, clean data folder that does not have access to the files, cache and database of the main profile, it is not just a folder with a password, but a full-fledged virtual machine with its own user ID.

It's important to understand that CPU and RAM resources are shared between two active environments, even though visually you only see one. Insulation ensures that applications installed in the second space cannot read data from the first without your direct permission, creating a strong barrier to potential information leaks if one of the applications turns out to be malicious.

Each space has its own system settings, including wallpaper, calls, widget location, and even connected Google or Mi Account accounts. You can log into your work profile with corporate email, and use your account in person, and the notification systems of these services will never overlap.

⚠️ Attention: System resources (RAM) are more intensive when activated in Second Space; on low-cost models with less memory, this may lead to more frequent unloading of background applications from the main profile.

From a file system perspective, the second profile data is stored in a secure directory that is restricted to superuser rights for normal applications, meaning that even if you connect your phone to your computer in file transfer mode, you won’t see the contents of the second space without unlocking the smartphone itself and switching the profile.

Key use cases for different categories of users

The main purpose of the Second Space is to segment the digital života. Consider the most popular scenarios where it is most beneficial. First of all, it is the separation of work and leisure. By installing work messengers (Telegram Business, Slack, Zoom) in the second profile, you can completely turn it off after hours, leaving the main phone free for personal contacts.

The second popular scenario is privacy, where you can store bank apps, crypto wallets, and photo galleries in a second space, protected by a separate password or fingerprint, and even if you hand an unlocked phone to a friend to show a photo from their primary profile, they can't switch to a hidden profile without additional authorization.

• 🔒 Security: Isolating financial applications from potentially dangerous games or programs from unknown sources.
• 💼 Operating Mode: The ability to have two different accounts on the same app (like two WhatsApp or Instagram) without using the cloning feature, which sometimes works unstablely.
• 👶 Parental Controls: Creating a safe environment for children where there is no access to your personal correspondence, browser history or the ability to make purchases.
• 🧪 Testing: Installation of doubtful APK-files or beta versions of programs in an isolated environment to avoid clogging the main profile.

It's also useful for people who have multiple projects or hobbies, such as one profile that can be set up solely for creativity with relevant drawing and note-taking apps, and another for entertainment and social media, switching between them in seconds, changing the context of the device's use.

Step-by-step: activation and initial setup

The process of turning on the feature takes no more than a minute and does not require complex manipulations. First, you need to go to the main settings menu of your Xiaomi or Redmi device. Find the section, which is usually called About Phone or Advanced Settings, depending on the version of the MIUI shell. However, in most current versions, the path looks like this: Settings → Second Space.

Once you log in, the system will prompt you to review a brief description of the feature. Click on “Enable Second Space” and then start the process of creating a new profile, which can take anywhere from 30 seconds to several minutes, depending on the speed of writing your smartphone drive.

The system will suggest you set up a second space, and here's an important security feature: you can assign a separate password, a pattern lock, or you can attach a separate fingerprint to enter the second profile, and that allows you to switch between spaces directly from the lock screen, just by attaching the corresponding finger.

Once you have completed the setup, you will be in a clean interface that resembles the phone you just bought, and you will need to re-set the basic setting: select a language, connect to Wi-Fi, and log into your Google account. Don't miss this step, because without an account binding, many functions of the applications may not work properly.

⚠️ Note: When you first start the second space, the system may request permission to access the contacts or gallery of the main profile.

Application management and data transfer between profiles

One of the main features of the Second Space is that it allows you to manage data portability flexibly, so you don't have to install all applications manually again, but you have a "Data Transfer" feature in the second space settings (available via swipe right or system settings).

This tool allows you to select specific applications from the main profile and install copies of them in the second one, and it is important to note that these are copies: game progress or messaging history in messengers by default are not carried over if the application does not support cloud sync. You get a clean installation of the application.

To share files (photos, videos, documents), you use a special shortcut in the gallery or file manager. When you take a photo in the second space, it is stored in the local gallery of this profile. To show a photo to someone in the main profile, you need to click the "Show in the first space" button (the icon with arrows), after which the file will appear in the corresponding folder of the main profile.

Deleting apps in the second space is standard and doesn't affect the main profile, so if you delete Instagram in the second space, it stays functional in the first space, and that gives you complete freedom to experiment with the software.

Tip: Use the Quick Switch feature in the notification curtain to instantly change your profiles without going through the lock screen every time.

Security setting and hiding the second profile

Security is a priority №1 when using split environments. Xiaomi provides multiple layers of protection. The most reliable method is using biometrics. Set up the fingerprint input so that the thumb of the right hand opens the main profile, and the finger of the left hand (or any other) immediately switches the phone to the second space.

In addition, you can completely hide the presence of the second space, you can activate the option “Hide the second space” in the settings of the function, in which case the icon of the application “Second space” will disappear from the menu of the main profile settings, you can enter the hidden profile only through a specially created shortcut on the desktop or a combination of actions known only to you.

Remember, passwords. Even if you use a fingerprint, install a complex digital code or a pattern lock. It's an insurance policy in case the fingerprint sensor fails or gets damaged. The password for the second space must be different from the password for the main one to prevent random login.

You should also pay attention to the permissions for specific applications. Even in the second space, check what rights you give to new programs. Although the isolation is strong, the application that accesses the microphone or camera in the second profile will use these hardware components, and the activity indicator may be less noticeable if you do not follow the status bar.

⚠️ Note: If you forget the password from the Second Space, it will be almost impossible to restore access to data inside it without resetting the entire phone.

Impact on productivity and autonomous operation time

There's a myth that having two spaces kills a battery, and the reality is that if the second space is running and applications are running, they consume energy, but if you just create a profile and rarely log in, the impact on autonomy is minimal, because the processes in it are frozen by the system.

The main burden falls on RAM. System services must serve two sets of settings and background processes. on Xiaomi’s flagship models with 8 GB or more of memory, this is completely invisible. On budget devices with 3-4 GB of memory, you can see more aggressive downloading of applications from memory when switching between spaces.

To minimize the impact on performance, it’s a good idea to avoid having heavy apps in the second space that you don’t need right now, for example, if you’re using the second profile only for banking once a week, don’t keep your navigators or games running there.

However, for most users, the trade-off between a slight decline in performance and a gain in privacy is entirely justified, and the stability of the system does not suffer, since the feature is a native part of the MIUI shell.
