Changing a smartphone is always stressful, especially when it comes to preserving your digital communication history. Unlike instant messengers, which store all data exclusively on servers, WhatsApp uses a hybrid storage system, where media files and a database of key conversations are located directly in the memory of your device. That is why simply logging into an account on a new phone does not guarantee the automatic reappearance of old correspondence without prior preparation.
The process of migrating data between devices based on Android has become much easier with the release of security system updates and integration with cloud services. However, many users still encounter errors when restoring or losing some of their attachments. Below we will analyze in detail the official transfer methods, hidden file system settings and nuances that are rarely written about in standard references.
Preparing an old device for data migration
Before starting the procedure, you need to make sure that your current device is completely ready to create a digital copy. The operating system Android requires an active account Googleas it serves as the access key to the cloud storage. Without being linked to Gmail, automatic creation of a backup copy in the cloud will be impossible.
Go to the messenger settings and check the current data safety status. To do this, open the menu Settings → Chats → Chat backup. Here you will see the date of the last save and the size of the archive. If the date is too old, force start the process by clicking on the button Backup.
- 📶 Make sure that the smartphone is connected to a stable network Wi-Fisince loading gigabytes of photos and videos over the mobile data may take hours or exhaust your data plan.
- 🔋 Connect the device to a charger to ensure the battery level does not drop below 50% while creating an archive.
- 📁 Check your free space on Google Driveas the backup does not count towards storage quota only if it was created recently and complies with the service rules.
⚠️ Attention: If you use encryption of backups with a password or 64-digit key, be sure to write them down. Without this data, it will be technically impossible to restore chats on a new phone, even knowing the password for your Google account.
Before creating a copy, remove large unnecessary video files from chats - this will speed up the process of uploading to the cloud and save disk space.
Method 1: Classic transfer via Google Drive
This is the most reliable and recommended method by developers that minimizes the risks of data loss. The principle of operation is to upload an encrypted archive to Google servers, from where it is subsequently downloaded to a new device upon authorization. It is important to understand the difference between a local backup and a cloud backup: the first is stored only in the phone’s memory, the second is accessible from anywhere in the world.
On the new smartphone, perform the initial system setup and log in to the same account Googlethat was used on the old device. Install the latest version WhatsApp from the store Google Play. When you first launch the application, it will automatically detect the presence of a backup in the cloud and offer to restore it.
The recovery process can take from several minutes to an hour depending on the speed of the Internet connection and the amount of data. During this time, do not minimize the application or lock the screen. The system will sequentially unpack the SQLite database and begin to pull up media files.
| Parameter | Local copy | Cloud copy (Google) | Manual file transfer |
|---|---|---|---|
| Speed | High (local network) | Depends on the Internet | Average |
| Reliability | Average (risk of phone breakdown) | High | Low (risk of errors) |
| Complexity | Low | Low | High |
| Requirements | Access to files | Google account | PC or cable |
Method 2: Local transfer without using the cloud
Sometimes users do not want or cannot upload personal data to the cloud for privacy reasons or due to the lack of fast Internet. In such cases, you can use the method of directly copying database files. This method requires a deeper understanding of the file system Android.
On the old device, use the file manager to find the directory where the databases are stored. In modern versions of Android, the path usually looks like Android/media/com.whatsapp/WhatsApp/Databases or classic WhatsApp/Databases at the root of the internal memory. Find the file named msgstore.db.cryptXX, where XX is the encryption version number.
Copy this file to your computer or directly transfer it to a new smartphone via Bluetooth, Wi-Fi Direct or USB cable. On the new device, place the file in the same directory to installation and launch of the messenger. When installing the application, it will detect a local file and offer to restore history from it, ignoring the cloud copy.
Nuances of encryption versions
Database files have the extension .crypt14, .crypt15, etc. The number indicates the version of the encryption algorithm. If you're transferring a file from an old phone to a very new one (or vice versa), there may be a version conflict. In this case, the recovery will not take place automatically. Solution: Update WhatsApp on both devices to the latest version before copying the file.
⚠️ Attention: When manually copying, make sure you do not rename the database file. The file name must remain unchanged, otherwise the application will not be able to recognize it as a valid backup copy.
Data transfer when changing SIM card and number
A frequent scenario is that buying a new phone is accompanied by a change of telecom operator and, therefore, the phone number. Many people mistakenly believe that when they change their number, their chat history is lost. In fact, the account WhatsApp is linked to the number, but the data is stored separately. The key step here is the function of changing the number inside the application itself.
The procedure must be started on the old device, if it is still in working order. Go to Settings → Account → Change number. Enter your old and new phone numbers. The system will offer to notify contacts about the change of number and transfer information about groups and settings.
After performing this operation, create a fresh backup copy. On the new phone, insert a new SIM card, install the application and log in, indicating the new number. Since you completed the number change procedure on your old device, the servers will recognize the continuity of the account and offer to restore chats from the latest copy.
- 📱 Make sure that the new SIM card is active and capable of receiving SMS or calls to confirm the registration code.
- 🔄 Do not delete the application from the old phone until the transfer to the new device is complete.
- 📞 If the old phone is unavailable, it is impossible to restore chats to a new number without first changing the number in the application - registration of a new clean account will begin.
☑️ Checklist before changing your number
Solving problems with two-factor authentication
One of the most common reasons for blocking the recovery process is forgotten PIN two-factor authentication. This security feature requires you to enter a six-digit code when registering a number on a new device. If you don't remember the code, the chat recovery process will be paused.
If you have associated an email address with two-step verification, you can reset your PIN via an email with a reset link. Otherwise you will have to wait 7 days. During this period, you will be able to use the application, but will not be able to verify the number on a new device with history restored.
It is worth noting that waiting 7 days will not lead to the deletion of your cloud backup unless you delete the account completely. However, old local copies on the phone may be overwritten by new, empty databases when attempting to register, so proceed with caution.
ℹ️ Information: Security settings interfaces may vary depending on the version of Android and the manufacturer's skin (for example, MIUI or OneUI). Always check the location of menu items with the current version of the application at the time of setup.
Two-factor authentication protects your account from theft, but requires discipline: always remember the PIN code or use a password manager to store it.
Frequently asked questions (FAQ)
Is it possible to transfer chats from Android to iPhone?
Direct transfer via Google Drive is not possible, since the systems use different encryption formats. To migrate from Android to iOS, you need to use a cable (Lightning/USB-C) and the “Transfer data to iOS” function when initially setting up your iPhone, or third-party paid utilities for your computer.
What to do if the recovery is stuck at 99%?
Most often this is due to an unstable Internet connection when downloading media files. Try switching from Wi-Fi to a mobile network or vice versa. If that doesn't help, delete the app, clear the cache, and try restoring the copy again, making sure you have enough free memory on your phone.
Will my groups disappear after the transfer?
No, information about groups is stored in the chat database. After recovery, you will automatically return to all groups in which you were a member. However, you will remain an administrator of the group only if you did not voluntarily leave it before the transfer.
Are privacy settings transferred?
Yes, settings like “Who sees my status”, “Profile photo” and “Visit time” are tied to the account and will be restored automatically. The exception is notification settings for specific chats, which sometimes need to be configured again.
Do you need to delete WhatsApp from your old phone?
It is recommended to do this only after you make sure that all chats and media files are restored correctly on the new device. Simultaneous operation of one account on two phones is impossible - when activated on a new device, the session on the old one will be terminated.
