Changing a smartphone is always an exciting process, but most often it is overshadowed by the thought of how to now drag all the content accumulated over the years to a new device. Fortunately, the ecosystem Android offers many convenient tools that eliminate the need to connect gadgets with wires or manually transfer files. Using cloud storage is one of the most reliable and universal migration methods, which works even if you don’t have a computer or cable at hand.
In this article we will analyze in detail the mechanisms of cloud synchronization, starting from basic Google accounts and ending with third-party solutions from manufacturers. You'll learn how to properly prepare your old phone so that no important contacts or photos get lost in the process. Modern operating systems make this process almost transparent to the user, requiring only minimal participation on your part.
Before delving into the technical details, it is worth noting that the success of the entire operation depends 90% on preparation. An unstable Internet connection or an outdated software version can be a serious obstacle. So we'll start by checking the initial data and setting up an account, which will be the key to your digital treasures on your new device.
Preparing a Google account and basic synchronization
The foundation for transferring data in the Android ecosystem is your account Google. It is the one that connects all your devices into a single network and stores key information on the company’s servers. Before you begin the transfer, make sure that your old phone is fully synchronized. To do this, go to the menu Settings → Accounts and select your Gmail profile.
Here you will see a list of services whose data can be stored in the cloud. Typically this includes contacts, calendar, notes, and application data. It is important to make sure that the switches opposite the desired items are active. If you see a refresh icon or a Sync button, click it to ensure that the latest information is uploaded to the server.
- 📸 Photos and videos: Make sure that the Google Photos app has the Backup and Sync feature turned on.
- 📞 Contacts: Make sure that contacts are saved to your Google Account and not to memory phone or on a SIM card.
- 📅 Calendar and Tasks: This data is synchronized automatically when your account is active, but it is worth checking their availability in the web version.
⚠️ Attention: If you use multiple Google accounts on your old device, make sure you synchronize the data exactly from the profile that you plan to use on your new smartphone. Data from different accounts is not automatically combined.
Particular attention should be paid to where your contacts are physically stored. Often, out of habit, users save numbers to the device’s memory, which makes them unavailable for cloud synchronization. In this case, before transferring, you need to export them to your Google account through the Contacts application. This will take a couple of minutes, but will save you from losing important numbers.
Backup settings and application data
In addition to media files and contacts, it is critical to save system settings and data from installed apps. In modern versions of Android, this feature is built deep into the system and is called Google Backup. It allows you to save Wi-Fi passwords, screen settings, system language, and even the home screen layout.
To initiate the creation of the last backup before changing your phone, go to section Settings → System → Backup. Here you will see the status of the last copy and the time it was created. If the date does not suit you, click the "Start copying" button. The process may take some time depending on the amount of data and Internet speed.
☑️ Ready for backup
It is worth noting that not all applications support full data recovery via the cloud. Developers themselves decide what data can be uploaded to Google servers. Games with progress are usually saved through services like Google Play Games, and instant messengers often have their own backup systems, which we will discuss below.
What exactly is saved in a Google backup?
The backup includes: a list of installed applications, system settings (brightness, sound, sleep mode), Wi-Fi passwords, data from most applications (if the developer has allowed), call history and SMS (on some models). Not saved: files in the "Downloads" folder, music downloaded from third-party sources, and data from applications that use their own encryption.
Multimedia transfer: photos, videos and documents
The largest block of data is your photos and videos. For their transfer, the service remains the most effective tool Google Photos. Unlike standard system backup, this service creates a separate library in the cloud, accessible from any device under your login.
The process is extremely simple: install the application on your old phone, log in to your account and wait for the download to complete. Synchronization status is displayed at the top of the feed. After all the photos appear in the cloud, just log into the same account on a new smartphone, and the entire gallery will become available instantly.
| Option | Space saving (High quality) | Original quality |
|---|---|---|
| Compression photo | Yes (up to 15 MP) | No (full size) |
| Video compression | Yes (up to 1080p) | No (original) |
| Space limit | Free (within 15 GB) | Spends space out of 15 GB |
| Print quality | Excellent up to A3 format | Professional |
If you prefer to store files in their original form without any compression, you will have to monitor the amount of free space in your Google storage. The standard 15GB often fills up very quickly, especially if you're actively shooting 4K video. In this case, it makes sense to consider a Google One subscription or use of alternative clouds.
Use the Free up space feature in the Google Photos app after syncing is complete. It will safely delete copies of photos from the phone's memory that are already in the cloud, freeing up gigabytes of space.
Migration of messenger data (WhatsApp, Telegram, Viber)
Messengers are a separate category of applications, since they store correspondence and media files locally or on their own servers, ignoring the standard Android backup. To transfer chat history, you must use the built-in functions of each specific application.
In the case of WhatsApp, the process requires explicitly creating a backup copy on Google Drive within the settings of the messenger itself. Log in Settings → Chats → Chat backup and click "Backup". Only after the current date and time of the copy appears, you can restore the data to a new phone when installing the application for the first time.
⚠️ Attention: When transferring WhatsApp to a new phone with a different operating system (for example, an iPhone), the standard method via Google Drive will not work. In this case, you need to use a special cable or paid utilities from phone manufacturers.
Telegram it is designed differently: the entire correspondence history is stored on the messenger servers. You don't need to copy anything manually. You just need to install the application on a new Android smartphone, enter your phone number and verification code. All chats, channels and files (except secret chats) will be loaded automatically.
Use of manufacturers' proprietary clouds
Many smartphone manufacturers create their own add-ons for Android and offer alternative clouds services that are sometimes more convenient than standard solutions from Google. For example, device owners Samsung can use Samsung Cloud, and users Xiaomi — Mi Cloud.
These services often allow you to make deeper backups of the system, including the location of icons on the desktop, specific interface settings and even design themes. However, they have one significant drawback: brand attachment. If you change Samsung to Xiaomi, you won’t be able to transfer data from Samsung Cloud.
However, if you stay within the same brand, a branded cloud can be an excellent addition to your Google account. It allows you to quickly deploy a clone of your old phone on a new device. Typically, the setup is offered immediately when you turn on a new gadget for the first time in the initial setup wizard.
Branded clouds are convenient when changing a phone to a model from the same manufacturer, but for a cross-platform transition (between different brands) it is more reliable to rely on the Google ecosystem.
Data recovery on a new device
When the old phone is prepared and all backups have been created, the most important stage begins - setting up a new smartphone. When you turn on your new device for the first time, the system will prompt you to copy data and settings. Select the "Next" option and connect to the Wi-Fi network.
At the sign in stage, enter the same Google data that you used on your old phone. The system will automatically detect available backups. You will be offered a list of backups indicating the date and model of the device from which they were made. Select the latest version.
Settings → System → Additional settings → Recovery and resetAfter selecting a copy, the process of downloading applications and settings will begin. The phone may reboot several times. Do not interrupt this process and keep the device connected to charging, since active data downloading and indexing consume a lot of battery power.
⚠️ Attention: Menu interfaces and item names may vary slightly depending on the version of Android and the manufacturer’s shell (MIUI, One UI, ColorOS). If you do not find the specified path, use the search for settings by entering the word “Recovery” or “Backup”.
When the process is complete, check for contacts, photos and basic settings. Applications will be downloaded in the background, so their icons may appear on the desktop gradually. To log into some banking applications or social networks, you will need to re-authorize for security purposes.
