Data portability to Xiaomi Poco X3: the full guide

Buying a new smartphone, especially one as powerful as the Poco X3, always evokes mixed feelings: the joy of owning a fresh gadget and the slight anxiety of the need to migrate all the data accumulated over the years. The process of transitioning from an old Android device to the Xiaomi platform can seem like a complex maze of settings, but in fact modern technology allows you to do it as quickly and painlessly as possible for the user.

In this article, we will discuss in detail all available ways of information migration, from using the proprietary Mi Mover utility to classic cloud services. You will learn how to save the folder structure, not lose important dialogs in messengers and correctly configure a new device so that it immediately starts working in the usual mode.

Whether you had a phone before, whether it was Samsung, Honor or Realme, the principle of data transfer remains similar, but there are nuances specific to the shell MIUI or HyperOS. We will pay attention to them to avoid the typical mistakes that beginners face when first starting a device.

Preparing devices for data migration

Before you run any copying software, you need to do basic training on both smartphones, which is a critical step, as an unstable connection or lack of space can interrupt the process in the middle, which will lead to corrupt files or loss of information.

Make sure both devices have a battery level of at least 60-70%. Active data transfer, especially over Wi-Fi Direct, can be a significant energy drain. Also check for free space on the Poco X3: the amount of memory available should exceed the size of the data you plan to transfer.

💡

Before you start the transfer, clean the old phone of temporary files and app cache – this will speed up the process and eliminate the transfer of digital garbage.

Both smartphones must be connected to the same Wi-Fi network if you plan to use cloud methods or LAN transmission. However, the Internet is not necessary to work with Mi Mover, since the application creates a direct connection between devices.

• 🔋 Charge both smartphones to at least 60% or connect them to a power source.
• 📶 Make sure that Wi-Fi and Bluetooth are activated on both devices.
• 💾 Check the free space on the internal Poco drive X3.

It is also important to update the system software on your old phone to the latest available version, which minimizes the risk of compatibility conflicts when transferring contact and messaging databases.

Using the Mi Mover app for quick migration

The most effective and native way for Xiaomi ecosystem is to use the pre-installed Mi Mover app, which is designed specifically to transfer data from android to android Xiaomi with minimal losses and maximum speed.

On the new Poco X3, the app is usually already installed in the Tools folder. Launch it, accept the terms of the agreement, and select the "I am the recipient" role. On the old device, you will need to download Mi Mover from Google Play or the official site if it is not there, and select the "I am the sender" role.

After selecting roles on the screen of the new phone will appear QR-Scan it with the camera of the old device, and the devices will connect over a secure channel, and you will see a list of data categories available for transfer. The system will offer you to select contacts, messages, call history, photos, music, videos and even installed applications.

The Mi Mover is a feature that tries to save not only the files themselves, but also their structure. However, it is worth considering that the settings of some specific applications may not be transferred due to the security limitations of Android. After selecting categories, click the "Send" button and wait for the process to be completed. Transfer speeds can vary from 5 to 20 MB / s depending on the quality of the Wi-Fi modules.

Synchronization through Google Account and Cloud Services

If you’re already deeply integrated into Google’s ecosystem, the data transfer can be done automatically when you activate Poco X3 for the first time, ideal for those who want a clean system while retaining all the important personal records and settings.

When you first turn on your new smartphone, the system will prompt you to log in to your Google account. By entering the same login and password as on the old device, you will get access to synchronized contacts, calendar events and notes. Photos and videos, if the old phone was enabled to sync Google Photos, will appear in the gallery automatically as you download from the cloud.

For apps, this method works like a shopping list: the phone will “remember” which programs were installed and prompt you to download them again, and the data inside the applications (game progress, correspondence) will only be saved if the applications themselves support backup in the Google Drive cloud.

⚠️ Note: Google sync does not transfer files lying in arbitrary folders of internal memory (for example, downloaded files from Telegram or music downloaded from a browser) unless they are in standard media libraries.

Manual transfer of files via computer

For users who are used to having complete control of the file system, or to transfer hundreds of gigabytes of data if necessary, the best choice is to use a PC, a method that allows visually sorting information and avoid duplicates.

Connect your old smartphone to your computer through USB-In the notification curtain, select the mode of operation USB «File transfer» (MTP). Open My Computer on your PC, find the device and copy the folders DCIM (Photos and videos), Download, Documents and other required directory to your computer's hard drive.

Then connect Poco X3. It's important to choose the right port. For fast transfer of large amounts of data, use the original cable and USB 3.0 port (usually blue) on your computer. Copy the saved folders into the internal memory of the new smartphone, observing the directory structure.

After copying media files, remember to transfer the messenger database separately if the automatic methods did not work. For WhatsApp, for example, you can create a local backup on an old phone, transfer the msgstore.db.crypt file to the new phone to the WhatsApp/Databases folder and restore it when you first install the application.

Transfer of messages and call history

One of the most delicate tasks is to keep the history of SMS and call logs, and standard Android tools are hard to do, but the Mi Mover app that I mentioned earlier does a great job of doing that, and if you use a different method, you'll need specialized software.

We recommend using the proven SMS Backup & Restore app. Install it on both phones. On the old device, back up, select save on Google Drive or locally. The backup file will have the.xml extension.

If you saved a file locally, transfer it to Poco X3 in any convenient way (Bluetooth, messenger, cable). Launch the application on a new phone, specify the path to the file and click Restore. The system will request permission to install the application by default for SMS — agree, otherwise the recovery may not be correct.

• 📱 Install an assistant app on both devices.
• 💾 Create a full backup copy SMS and MMS old-phone.
• 🔄 Transfer the backup file to Poco X3.
• ✅ Recover the data and check for all numbers.

⚠️ Attention: When restoring SMS On the new device, old messages can be duplicated if synchronization is performed. SIM-The maps have already happened. It is recommended to do a full backup before experiments.

Solutions and adjustments after transfer

Once the data is moved, the Poco X3 can run slower for a while than usual. That's okay: the system indexes files, optimizes databases, updates the app cache, and let the phone lie on a charger with the lock screen on for about an hour.

Check key applications. Some banking applications or secure services may require re-authorization or reconfiguring biometrics for security reasons, a standard procedure for Android to change the hardware identifier of the device.

💡

After migrating, be sure to check notification settings for important applications, as in MIUI they may be limited by default to save charge.

You should also go to your Mi Account settings and make sure that your Xiaomi Cloud sync is enabled for contacts and notes, which will create an additional restore point in case you lose your device in the future. Remember to remove your old device profile from your trusted list in your Google account if you no longer plan to use your old phone.
