Buying a new smartphone always causes mixed feelings: the joy of owning advanced technology and slight panic from the need to transfer gigabytes of information accumulated over the years. Migrating to a new Android phone has become much easier over the past few years, but still requires careful consideration so as not to lose important contacts or photos.
Modern ecosystems offer many migration options, from cloud services to direct cable connections. The specific method you choose depends on the brand of your old device, operating system version, and the amount of data you need to move. In this article, we will analyze in detail each of the available options.
Before starting the procedure, make sure that both devices are charged at least 60-70%. The process of syncing and downloading large amounts of data consumes a significant amount of power, and a sudden power outage can result in write errors or file corruption. It is best to leave both devices connected to chargers throughout the entire operation.
Preparing the old device for migration
Successful data transfer is 90% dependent on how well you prepare the old smartphone. The first step is to clear out the junk and remove unnecessary files that you don't plan to transfer. This will not only speed up the copying process, but will also free up space on the new gadget for really important things.
Be sure to check for current updates for the system and key applications. Developers often release patches to improve the stability of backup tools. Go to Settings → System → System update and install available updates, if any.
Particular attention should be paid to banking and instant messenger applications. Some financial apps require you to re-pair your device or deactivate it on your old phone before activating it on your new one. Take screenshots of important settings or save passwords in a password manager so you don’t waste time recovering them.
⚠️ Attention: If you use two-factor authentication (2FA) via SMS or an authenticator application, make sure that the SIM card will work in the new phone immediately after turning it on, or first transfer the access keys to the authenticator cloud service.
Don't forget to check the status of the internal memory. Fragmented data may copy more slowly. Use built-in cleaning tools or third-party utilities to optimize storage before starting the transfer procedure.
☑️ Preparing to transfer data
Using a Google account for cloud transfer
The most universal and reliable way to transfer data between any Android devices is to use a cloud service Google One and system backup. This method is ideal if you don’t have a cable on hand or if the phones are in different places.
First, go to the settings of your old phone and select the section Google → Backup. Here you will see a list of data that will be saved in the cloud: contacts, call history, SMS messages, device settings and application data. Press the button "Start copying" and wait for the process to complete.
When you turn on your new smartphone for the first time, log in to the same Google account. The system will automatically offer to restore data from the latest backup. You can choose which apps and settings you want to return. This process can take from 15 minutes to several hours depending on the Internet speed and the amount of data.
It is worth noting that photos and videos by default are often synchronized through the service Google Photos, and not through a general system backup. Make sure the Google Photos app on your old device has sync enabled and all media files are uploaded to the cloud (cloud icon with a check mark).
Use 5 GHz Wi-Fi to speed up backup downloads. Mobile data may be too slow for gigabytes of data and will quickly exhaust your data limit.
It is important to understand the limitations of Google's free plan, which provides 15 GB of storage. If your archive exceeds this volume, the system will offer to purchase additional space or skip some data. In this case, it is better to use other methods or temporarily clear the gallery.
Direct connection via cable (Smart Switch and analogues)
For owners of Samsung devices and many other brands, the fastest method is to directly connect two phones using a USB-C to USB-C cable (or an adapter). proprietary utilities, such as Samsung Smart Switch, Xiaomi Mi Mover or OPPO Clone Phone, allow you to transfer terabytes of data in a matter of minutes.
The process is as follows: install the transfer application on both devices (on new ones it is often pre-installed). Launch the app on the new phone and select the "Receiver" role, and on the old one - "Sender". Connect the devices with a cable.
After connection, the system will scan the contents of the old device and prompt you to select categories for transfer. You can select everything at once or mark only specific folders, for example, only contacts and messages, leaving heavy videos on the old drive.
| Transfer method | Speed | Required equipment | Reliability |
|---|---|---|---|
| Google Account | Average (depending on Wi-Fi) | Stable internet | High |
| USB Cable | Very high | USB-C cable / Adapter | Maximum |
| Wi-Fi Direct | High | No (built-in module) | Medium |
| SD Card | Low/Medium | Memory card and slots in both phones | High |
The advantage of the cable method is that it copies data locally without using Internet traffic. In addition, some utilities can even transfer the arrangement of desktop icons and alarm clocks, which creates the feeling that you just changed the phone case.
Wireless transfer via Wi-Fi Direct
If you don’t have a suitable cable at hand, most modern smartphones support creating a direct wireless network between devices. Known as Wi-Fi Direct, this technology allows you to transfer files at speeds comparable to a wired connection, but without the hassle of wires.
When setting up a new phone, Android often automatically suggests finding the nearest device to transfer data to. A QR code or request to create an access point will appear on the screen. The old phone must connect to this temporary network created by the new device.
After the connection is established, the interface will prompt you to select data to transfer. This method is especially useful when moving between devices from different brands, where branded cables may not fit and the cloud is crowded. However, make sure that the phone screens do not go dark during the transfer.
⚠️ Attention: When using the wireless method, do not move too far from the router and devices. Although the connection is direct, strong interference from other Wi-Fi networks in the apartment building can slow down transmission speeds or cause the connection to drop out.
Some manufacturers implement their own protocols on top of Wi-Fi Direct. For example, Huawei Phone Clone or Motorola Migrate create a secure tunnel for data transfer. The principle of operation is similar: scanning a QR code and automatically transmitting data packets.
What to do if the wireless connection is constantly interrupted?
Try switching one of the phones to airplane mode, leaving only Wi-Fi on. This will prevent the device from trying to switch to the mobile network or Bluetooth, which can interfere with the data transmission channel.
Manually transferring files via a computer and SD card
Sometimes automatic systems fail, or the user only needs to transfer specific files, for example, heavy video projects or document archives. In such cases, the good old manual method via a computer or memory card remains the most reliable solution.
Connect the old phone to the PC via a USB cable and select the file transfer mode MTP in the notification shade. Copy the necessary folders (DCIM, Download, Documents) to your computer’s hard drive. Then connect the new phone and drag the files into the appropriate directories.
If both smartphones have a memory card slot microSDthe process is simplified even more. Insert the card into the old phone, transfer all media files to it, then remove and insert into the new device. The file manager of the new device will immediately see all the data.
This method gives complete control over what exactly ends up on the new device. You can audit your files directly on your computer, deleting duplicates or bad pictures before recording to a new phone. This is an excellent opportunity to put things in order in your digital household.
Manual transfer via a PC or SD card is the only way to guarantee transfer of files that are not supported by automatic migration utilities, for example, caches of certain games or system logs.
Transferring WhatsApp and Viber messages
A separate headache for many users is to transfer the history of correspondence in instant messengers. Standard Google backup often does not save complete media archives or chat settings as desired. WhatsApp and Viber have their own built-in mechanisms.
In WhatsApp you need to go to Settings → Chats → Chat backup. Make sure the copy is created in Google Drive and not locally on your phone. When installing WhatsApp on a new device and entering the same phone number, the application itself will offer to restore history from the cloud.
For Viber the procedure is similar: More → Settings → Account → Viber backup.
There are nuances when moving between different operating systems (for example, from iPhone to Android), but within the Android ecosystem the process is usually seamless. If automatic recovery does not work, you can try creating a local copy on your old phone, transferring the database file via PC to a folder /Android/media/com.whatsapp/WhatsApp/Databases on your new phone before launching the application for the first time.
⚠️ Attention: Restoring a WhatsApp backup is only possible when installing the application for the first time. If you have already activated WhatsApp on your new phone without restoring, you will have to uninstall the app, clear the data and install it again to see the restore button.
Frequently asked questions (FAQ)
Will data be deleted from the old phone after the transfer?
No, standard data transfer procedures work in copy mode, not cut mode. All your files, contacts and applications will remain intact on your old device. You can erase them manually only after you make sure that the new phone works correctly.
What to do if some applications are not installed on the new phone?
This can happen if the application has been removed from the Google Play Store or is not compatible with the version of Android on the new device. You will have to search for and install such applications manually via APK files or find their modern analogues in the store.
Is it possible to interrupt the data transfer process and start over?
Yes, you can interrupt the process at any time, but this may lead to partial data loss or errors in the operation of applications. If the transfer is stuck, it is better to restart both phones, reset the network settings and start the migration procedure again from the very beginning.
Are alarm settings and alarm clocks transferred?
When using a full backup via Google Account or proprietary utilities (for example, Smart Switch), alarm settings are usually saved. However, if you transfer manually or use only cloud contact syncing, your alarms may reset and will have to be set again.
How long does it take to transfer 100 GB of data?
Time varies depending on the method. Via a USB 3.0 cable the process will take about 15-20 minutes. Via Wi-Fi Direct - approximately 40-60 minutes. When using the Google cloud, the time will depend on the speed of your Internet channel and can take several hours.
