Buying a new smartphone always causes mixed feelings: the joy of owning a modern gadget and anxiety about the safety of data accumulated over the years. Photos, contacts, correspondence in instant messengers and application settings - all this makes up the user’s digital identity, which must be kept intact. Fortunately, the ecosystem has evolved significantly in recent years, offering several reliable tools for migration. Previously, the process of transferring information resembled a complex quest using a computer and many third-party apps. Today, device manufacturers build special utilities directly into the system, and services Android has evolved significantly in recent years, offering several robust migration tools.
Previously, the process of transferring information resembled a complex quest using a computer and many third-party apps. Today, device manufacturers build special utilities directly into the system, and services Google allow you to restore a backup in a couple of clicks. However, the choice of a specific method depends on the condition of the old device, the speed of the Internet connection and the amount of stored information.
In this article we will analyze in detail all the current methods of data migration, from classic cloud backup to direct cable connection. You will learn how to avoid common mistakes, what to do with encrypted data, and how to properly prepare both devices for the procedure so as not to lose a single important file.
Preparing devices for data migration
Before starting any copy process, it is critical to complete a number of preparatory steps. Ignoring this step often leads to failures in the middle of the procedure or partial loss of information. First of all, check the battery level on both smartphones.
The optimal solution is to connect both devices to a power source. If the battery shows 80%, a sharp jump in power consumption during active data transfer via Wi-Fi or processor operation can turn off the phone. Make sure that your new smartphone has enough free space to accept all the files.
⚠️ Attention: Before you start migrating, be sure to update the operating system on both devices to the latest version available. Differences in versions Android may lead to incompatibility of backup formats or errors in the operation of system transfer utilities.
It is also recommended to delete temporary files and application cache on the old phone. This will speed up the backup process and reduce the amount of data transferred. Go to Settings → Storage and clean out unnecessary garbage.
☑️ Preparing to transfer data
Method 1: Using a Google account and cloud storage
The most universal and simple method that works regardless of the brand of your smartphone. The ecosystem Google automatically synchronizes key data: contacts, calendar events, notes and system settings. First, go to the settings of your old phone and select the section Accounts.
Make sure that synchronization is enabled for all necessary items. Pay special attention Google Photos and Google Drive, since they store media content separately from the system copy. Start manual synchronization by clicking the update button to make sure that all the latest data is sent to the cloud.
On the new device, during initial setup, the system will prompt you to log in to the same account. After authorization, the setup wizard will ask if you want to restore your data from a backup. Select the latest version of the backup from your old device.
- 📱 Contact and phone numbers are restored almost instantly after logging into your account.
- 📸 Photos can be loaded gradually in the background as you use the phone.
- ⚙️ Wi-Fi passwords and lock screen settings are often transferred automatically via Google Smart Lock.
This method is ideal for basic migration, but has limitations on free storage. If you have terabytes of video, you will have to buy more space or use other methods. Remember that some applications do not save their internal data to the Google cloud, but require a separate backup.
If you are running out of space in Google Drive, temporarily delete old backups of other devices in the "Backups" section to make room for a new phone.
Method 2: Manufacturer's proprietary utilities (Samsung, Xiaomi, Huawei)
Large vendors understand the importance of a seamless transition and are developing their own powerful tools. For example, owners Samsung use the application Smart Switch, which is considered one of the most reliable on the market. It can even transfer the arrangement of icons on the desktop and alarm clocks.
Users Xiaomi and Redmi can use the built-in application Mi Mover. It works on the principle of creating a temporary Wi-Fi hotspot between two phones. The process is launched through the menu Settings → About phone → Mi Mover.
For devices Huawei and Honor application intended Phone Clone. The principle of operation is similar: scanning a QR code on an old device with a new phone establishes a direct connection. Such utilities often work faster than cloud methods, since they do not depend on Internet speed.
| Brand | Utility name | Connection type | Features |
|---|---|---|---|
| Samsung | Smart Switch | Cable / Wi-Fi | Move screen layout |
| Xiaomi | Mi Mover | Wi-Fi Direct | High transfer speed |
| Huawei | Phone Clone | Wi-Fi Direct | Support for iOS and Android |
| OnePlus | Clone Phone | Wi-Fi / Cable | Deep integration with OS |
The use of native software guarantees maximum compatibility of data formats. System settings specific to the manufacturer's shell (for example, themes or control gestures) will be transferred correctly only through these tools.
Proprietary utilities allow you to transfer not only files, but also specific interface settings that are not available when using standard Google tools.
Method 3: Direct connection via USB-C cable
If wireless transmission seems unstable or too slow, use a physical connection. Modern smartphones are often equipped with adapters USB-C to USB-C in the box. This is the fastest way to transfer gigabytes of data.
Connect both phones with a cable to each other. The new device's screen may ask you to allow access to your old phone's data. Confirm the action and select the file transfer mode (MTP) or a special copy mode, if offered by the system.
Many modern shells Android automatically recognize the connection of the second device and launch the migration wizard. All you have to do is select the categories of data to copy: messages, call logs, applications and media files.
⚠️ Attention: When using a cable, make sure it supports data transfer and not just charging. Cheap "charging only" cables will not allow you to establish a connection between devices.
The advantage of the cable method is the stability of the speed. You don't have to worry about Wi-Fi interference or the connection dropping because the user goes to another room. The process proceeds linearly and predictably until completion.
Transferring WhatsApp and Telegram correspondence
Messengers often become the most painful point when changing a phone, since their data does not always end up in the general system backup. For Telegram the situation is simple: the entire correspondence history is stored on the service's cloud servers.
All you need to do is install the application on a new device and enter the phone number. All chats, channels and media files will be loaded automatically. The only exception is secret chats, which are tied to a specific device and cannot be transferred.
With WhatsApp everything is more complicated. Here you need to create a local or cloud backup within the messenger settings before changing your phone. Go to Settings → Chats → Chat backup and click the "Create a copy" button.
- ✅ Google Disk: Select this option for WhatsApp so that the copy is linked to your Google account.
- 💾 Local: Saving to the phone memory is important if you transfer files manually via a computer.
- 🔐 Encryption: When creating a backup, you can enable end-to-end encryption, but do not forget to remember the password!
What to do if WhatsApp does not see the backup?
Make sure that on the new phone you are signed in to the same Google account as on the old one. Also check if the Google Play Services app is installed and updated to the latest version. Sometimes clearing the cache of the WhatsApp application itself before restoring helps.
When you launch WhatsApp for the first time on a new smartphone, the system will automatically detect an available copy and offer to restore it. You cannot refuse this offer if you want to return your message history, so the process will have to be completed completely.
Manually transferring files via computer
Sometimes automatic systems fail, or the user needs to transfer only specific folders, for example, downloaded documents or music. In this case, the good old method with a computer remains the most reliable.
Connect the old phone to the PC via a USB cable and select file transfer mode. Copy the necessary directories (usually DCIM for photos, Download for downloads, Music) to your computer’s hard drive.
Then disconnect the old device, connect the new one and copy the files to the appropriate folders in the internal memory. This method is good because you can immediately audit the files and not copy digital junk to a new device.
Folder structure for manual copying:/DCIM/Camera - photos from the camera
/WhatsApp/Media - media files from the messenger
/Download - files from the browser
/Music - audio recordings
However, it is worth remembering that the manual method will not transfer application settings, browser bookmarks or passwords. This solution is exclusively for media files and documents. For complete migration, it is better to combine it with cloud synchronization of your Google account.
Frequent problems and their solutions
Despite the smooth running of the processes, users may encounter difficulties. One common problem is that the process gets stuck at a certain percentage. This is often due to overheating of devices or unstable connections.
If the transmission is interrupted, do not panic. Check to see if one of your phones has power saving mode enabled, which may limit the operation of the Wi-Fi module. Disable it and try to resume the process from where it stopped, if the utility allows it.
⚠️ Attention: Never reset your old phone to factory settings until you are sure that all data on the new device works correctly. Keep the old device in working condition for at least a week after the transition.
Another difficulty arises with banking and security applications. Due to being tied to a specific Device ID, they may require re-authorization or even complete re-registration. Have your card details and support code words handy.
In some cases, applications are not installed automatically from a backup. This may be due to the fact that the application has been removed from the store Google Play or is incompatible with the new version of Android. You will have to search for and install such apps manually.
After transferring the data, go to the settings of each important application and check the permissions. Sometimes after migration, access to the camera or microphone is reset for security reasons.
Is it possible to transfer data if the screen of the old phone is broken?
Yes, it is possible, but it is more difficult. If the sensor does not work, but there is an image, connect a USB mouse via an OTG adapter for control. If the screen is black, but the phone responds to presses, try connecting it to the computer and managing it through apps like ADB or_scrcpy_, if USB debugging was previously enabled.
Will passwords from sites saved in the browser be transferred?
Yes, if you used synchronization in the browser (for example, Chrome). Just log into your Google account in the browser on your new phone, and all saved passwords, history and bookmarks will be downloaded automatically. Locally saved passwords that are not linked to an account are more difficult to transfer.
What to do with the SD card when changing your phone?
Physically move the card to the new slot. However, if the card was encrypted as internal storage (Adoptable Storage) on the old phone, the new phone will not be able to read it without formatting, which will lead to data loss. In this case, the data must first be copied to a computer.
How long does a complete data transfer take?
The time depends on the amount of information and the transfer method. 64 GB of data can be transferred via cable in 15-20 minutes. Over Wi-Fi, this process can take 40 minutes to an hour. Cloud recovery highly depends on the speed of your Internet connection.
Do you need to delete your Google account from your old phone before selling it?
Absolutely! Simply resetting is not enough. Before selling or transferring your device, go to your accounts settings and delete your Google profile. This will disable FRP (Factory Reset Protection), otherwise the new owner will not be able to activate the phone.
