Owning two SIM cards has become the standard for many smartphone users, especially those who share personal and workspace. However, while voice calls and SMS are clear, installing instant messengers is often difficult. Owners of Xiaomi, Redmi and POCO devices are in a better position, as the MIUI shell (and its new version of HyperOS) offers powerful built-in tools for managing multiple accounts.
The problem is that the standard WhatsApp app is tied to a phone number and doesn't allow you to log in to a second account. Trying to register a new number on an already active app will lead to an exit from the first profile. Fortunately, the company's engineers have made it possible to clone the apps, which allows you to run two independent copies of the messenger at the same time.
In this article, we will discuss in detail all available methods, from regular system tools that do not require the installation of third-party software, to alternative options for specific cases. You will learn how to properly configure notifications, avoid blocking from messenger servers and optimize battery performance when using two active profiles.
Use of the built-in Dual Apps feature on MIUI
The most reliable and energy-efficient way to launch WhatsApp to number two is by using the system’s Dual Apps feature, which is built directly into the MIUI shell and operates at the core level, which ensures stability and instant notifications, you do not need to download suspicious programs from unverified sources.
To activate this feature, you need to go to the smartphone settings. The path may vary slightly depending on the firmware version, but the logic remains the same. Find the section responsible for managing installed programs and select the clone creation function. The system will offer a list of applications that support duplication.
You'll see a standard WhatsApp icon and a clone on the list, and when you turn on the slider, you'll see a second messenger icon, usually marked with a special icon or a yellow frame, which is a full-fledged app with its own database, contacts, and correspondence history.
☑️ Setup of Dual Apps
It is important to understand that cloning consumes additional RAM resources. If you have a budget model of a smartphone with 3 or 4 gigabytes of RAM, the system can aggressively unload the background processes, in which case it is worth limiting animations or closing heavy games before activating a second account.
Step-by-step instructions for cloning WhatsApp
The second number setup process takes only a couple of minutes, but requires careful input, make sure that the second SIM card is installed in the phone and receives an SMS, or that you can take a voice call for verification.
Follow the algorithm to avoid errors:
- 📱 Open the settings of your Xiaomi device.
- 📂 Go to the Apps section (Apps).
- 🔁 Find the item Cloning applications (Dual Apps).
- ✅ Find in the WhatsApp list and turn on the switch next to it.
- 🆕 Wait for the copy to be created and find a new icon on your desktop.
Once the second icon appears, launch it. The messenger will ask you to accept the terms of use and ask you to enter the phone number. Enter the number of the second SIM card. The confirmation code will come to the standard message application if the SIM cards are not confused in the settings.
💡
If the code does not arrive in the SMS, select the option "Call me." The system will dial the number itself, and the robot operator will dictate the activation code.
The only way to recover the history of the second clone is from a backup of Google Drive, which was made specifically for this number. If you haven't previously saved the second number to the cloud, you'll have to start with a clean slate. You can't transfer chats from one phone to a clone inside the same device by standard means.
Alternative methods: Parallel Apps and third-party solutions
Some firmware versions or some POCO models may call it something else, like in game shells or lightweight versions of MIUI, the name Parallel Apps is used. The operating principle is identical, but the menu layout may be different, and sometimes this item is hidden in the Advanced Settings section.
If, for some reason, system cloning is not available (for example, on very old models or global firmware with cut-out services), you have to resort to third-party solutions. There are special container applications, such as Parallel Space or 2Accounts, which create a virtual environment inside themselves, where you can run a second WhatsApp.
But there are serious flaws in this method: It requires broad permissions, consumes more battery and often displays ads, and WhatsApp may view running in a virtual environment as a violation of the rules and temporarily suspend an account.
Risks of using third-party cloners
Also worth considering is the official WhatsApp Business app, which is designed for entrepreneurs, but works great as a second messenger for personal use, you can install a regular WhatsApp for one number and WhatsApp Business for the second, which is completely legal and developer-supported.
Set up notifications and energy saving
After installing the second messenger, users often face a problem: notifications come with a delay or do not arrive at all, this is due to Android’s aggressive policy to save battery power, the system “kills” the background processes of the second application, considering them unimportant.
To fix this, you need to manually configure the power saving settings for the cloned application:
- 🔋 Go to Settings. → Annexes → All applications.
- 🔍 Find a WhatsApp clone (it will be marked with an icon).
- ⚡ Select Saving Charge and set No Limits.
- 🔔 Also check notification settings and allow display on the lock screen.
Another important thing is auto-start. There's a separate Auto-Start menu in the MIUI shell, and find a second WhatsApp menu there and let it run with the system, which ensures that the messenger will work immediately after the phone is turned on, without waiting for the first manual launch.
💡
Without setting “No Limits” in the battery section, the second WhatsApp will not work stable and messages will only come after opening the app.
Do not forget to periodically check the updates of both applications in Google Play. Developers are constantly improving the messenger on two SIM cards, and the current version of the software is the key to stable communication.
Comparison of methods of launching the second account
To make it easier for you to choose the right option, we have prepared a comparison table that will help you weigh the pros and cons of each method depending on your needs and smartphone model.
| Method | Stability | Impact on the battery | Security |
|---|---|---|---|
| System Dual Apps | Tall. | Low (optimized) | Maximum |
| WhatsApp Business | Tall. | Medium (separate process) | Maximum |
| Parallel Space | Medium | High (double load) | Medium |
| Root-mods (not rivers) | Low. | Depends on fashion. | Low (ban risk) |
As the table shows, Xiaomi’s regular funds and the official Business app are the leaders, and the use of third-party “crutches” is justified only in extreme cases when the phone does not technically support cloning.
When choosing a method, you should also consider the amount of internal memory: a cloned application takes up space not only for the installation file, but also for media files. If you actively share photos and videos, memory can run out faster than expected.
Frequent problems and ways to solve them
Even with reliable system functions, there can be failures, and one of the common problems is that you can't verify it, and the server can write, "Time on the phone doesn't match," and then you go to the date and time settings and turn on synchronization over the network.
Another common situation is that the second WhatsApp stops connecting to the Internet, although the first one works normally. VPN Check if the static is installed. IP-address in the Wi-Fi settings for a cloned app, or try switching to mobile internet for diagnostics.
⚠️ Warning: Never try to install modified versions of WhatsApp (like GBWhatsApp or WhatsApp Plus) to solve cloning problems.This is a direct path to locking your number down by messenger servers.
If notifications are missing after a HyperOS firmware update, try resetting your network settings. Go to Settings → Connection & Sharing → Reset Wi-Fi, mobile networks and Bluetooth. This won’t delete your data, but will restart network modules, which often solves the problem of a suspended connection.
