How to transfer all data from one Android to another

Buying a new smartphone is always a joyful event, but it is inevitably associated with a routine migration procedure. You have to transfer contacts, photos, chat history and, most difficult, installed applications while maintaining their settings and account logins. Fortunately, the ecosystem Android has made this process as automated as possible in recent years, eliminating the need for the user to manually restore each app from the store.

There are several basic ways to complete this task, each of which has its own advantages depending on the brand of your device and the condition of the old phone. The most universal method is associated with an account Google, which is present by default on any certified device. Alternative solutions from manufacturers, such as Samsung Smart Switch or Xiaomi Mi Moverare often faster when connected directly. The choice of a specific tool depends on how deeply you want to integrate into the brand’s ecosystem or whether you prefer standard system tools.

In this article we will analyze in detail the algorithms of actions for each method, paying special attention to the nuances of transferring banking applications and two-factor authentication. You'll learn how to avoid losing important files and why simply copying folders through your computer may not work for modern apps. Be prepared for the process to take anywhere from 30 minutes to several hours, depending on the size of your digital life.

Preparing devices for data migration

Before beginning any transfer process, it is critical to ensure that both devices are operational and ready to sync. Charge both smartphones to at least 80%, since actively transferring large amounts of data via Wi-Fi or cable significantly consumes battery power. If one of the devices turns off during the migration process, this may result in database corruption or incomplete transfer of system settings.

You will also need to free up space on the new device. Even if you bought a phone with a large amount of memory, check whether the space is occupied by system updates or pre-installed software. Delete unnecessary files in advance so that the process is not interrupted during the copying of media files. Make sure that Wi-Fi and Bluetooth are turned on on both devices, as they are often used to discover each other's devices.

⚠️ Warning: If your old device has a lock screen (PIN, pattern, or fingerprint), be sure to remember it or keep the device unlocked. Some data transfer protocols require security confirmation on the receiving end, and locking the screen may interrupt the connection.

Check your operating system version. Although modern tools are cross-platform, working between devices with very different versions Android (for example, between version 8 and version 14) may require additional time to convert data formats. It is advisable to update both smartphones to the latest available software version before starting the procedure.

Using a Google account for backup

The most reliable and universal way to transfer data is to use cloud backup through services Google One. This method allows you to save not only your contacts and calendar, but also a list of installed applications, Wi-Fi passwords, and even desktop settings. To get started, go to the settings of your old phone and find the section System → Backup.

Activate the "Upload to Google Drive" switch and click the "Start copying" button. The system will analyze the installed applications and determine which of them support saving data in the cloud. Please note that some banking applications and instant messengers may not save chat history through this method for security reasons, requiring separate export within the application.

The backup process can take considerable time when using the mobile data, so it is strongly recommended to connect to a stable network Wi-Fi. Once completed, you will see the time of the last successful copy. On a new device, during initial setup, simply sign in to the same account Google, and the system will offer to restore data from the last available save point.

• 📲 Contacts and calendar events are synced instantly after logging into your account.
• 📸 Photos and videos are saved through the Google Photos service, if enabled autoload.
• 🔑 Passwords saved in the Google password manager will be automatically downloaded to the new browser.
• 📱 A list of applications will be downloaded from the Play Market, but their installation will begin only after connecting to Wi-Fi.

Direct transfer via cable (Cable Transfer)

If you have the ability to physically connect two smartphones, using a special adapter or USB-C to USB-C cable is the fastest migration method. This method, often called Cable Transfer, does not depend on the speed of your home Internet and allows you to transfer gigabytes of data in a matter of minutes. Modern versions of Android (starting from version 12) support this protocol at the system level without installing additional software.

First, connect the cable to both devices. The new phone will ask you to copy data from your old device. Follow the setup wizard and you'll need to confirm the connection on your old phone, possibly by entering a PIN. The system will automatically scan the contents of the old drive and prompt you to select categories of data to transfer.

Unlike the cloud method, cable transfer copies actual files, not just links to them. This means that your full-resolution photos, downloaded maps and offline music will be transferred directly to the internal memory of the new gadget. This is especially useful if you have limited traffic or slow Internet.

Data type	Transfer speed (approximate)	Reliability	Requirements
Contacts and SMS	Instant (< 1 min)	High	Any cable
Photo and Video (50 GB)	10-15 minutes	Very high	USB 3.0 cable
Applications (20 pcs)	5-10 minutes	Average	Stable connection
Settings systems	Instant	High	Android 12+

After the transfer is complete, the cables can be disconnected. A new phone may require a reboot to apply all system settings. Make sure that all application icons appear on the desktop before erasing data from the old device.

What to do if the cable is not detected?

If the system does not see the connection, try using the original cable that came with one of the phones. Cheap third-party cables often only support charging and not data transfer. Also check the connectors for dust.

Branded utilities of manufacturers (Samsung, Xiaomi, etc.)

Large smartphone manufacturers develop their own migration tools, which often work more efficiently than standard Android tools, especially when moving between devices of the same brand. For example, owners Samsung can use the application Smart Switchthat comes pre-installed on most of their devices. It allows you to transfer even the arrangement of icons on the desktop and alarm settings.

Users Xiaomi, Redmi and Poco should use the utility Mi Mover. The principle of operation is similar: install the application on both phones (or find it in the settings of the new one), create an access point and connect the devices. The peculiarity of such utilities is that they can often transfer data from system applications that are closed to standard Google backup.

⚠️ Attention: Branded utilities may not work correctly when transferring data from third-party devices. For example, Smart Switch may refuse to transfer system settings from a Huawei or Honor phone, limiting itself to only media files and contacts.
