The fastest way to move your WhatsApp messages
WhatsApp stores your messages in encrypted backups that live on Google Drive (Android) or iCloud (iPhone), not on WhatsApp's own servers. When you install WhatsApp on a new phone with the same phone number, the app asks whether you want to restore from that backup. If you say yes, your messages, photos, and voice notes come back — but only if you use the same type of phone (Android to Android, or iPhone to iPhone) and the same account that created the backup.
If you are switching from iPhone to Android or Android to iPhone, WhatsApp does not restore messages automatically. You will need to export your chats as files and move them manually, which is slower and does not include media files by default. The backup method works because WhatsApp encrypts the backup with a key only your phone can read, so even WhatsApp cannot see what is inside.
Key Takeaways
- Backups on Google Drive (Android) or iCloud (iPhone) restore automatically when you sign in to WhatsApp on a new phone with the same number, as long as you use the same operating system.
- Switching between iPhone and Android requires exporting chats as text files, which does not include photos or videos unless you move them separately.
- Your backup is encrypted with a key stored on your phone, so WhatsApp staff cannot read it even if they wanted to.
- Before you switch phones, check that your backup is recent and that you have enough storage space on Google Drive or iCloud for the backup to complete.
How to restore messages when staying on the same operating system
The easiest path is when you are moving from one Android phone to another Android phone, or from one iPhone to another iPhone. Your backup already exists on Google Drive or iCloud — you just need to sign in on the new phone and let WhatsApp find it.
On Android: Install WhatsApp from the Google Play Store. When you open it, enter your phone number. WhatsApp checks Google Drive for a backup linked to that number. If one exists, you will see a "Restore" button with the date of the most recent backup. Tap it. The restore takes a few minutes to an hour depending on how many messages you have. Do not close the app or turn off your phone while it is restoring.
On iPhone: Install WhatsApp from the App Store. When you open it, enter your phone number. WhatsApp checks iCloud for a backup. If one exists, you will see a "Restore Chat History" button. Tap it. Like Android, the restore can take several minutes. Stay in the app until it finishes.
Your messages, group chats, and media files (photos, videos, voice messages) all come back in the order they were sent. Your contact list does not restore — WhatsApp uses the phone's contacts, so you need those separately. Starred messages and chat wallpapers do restore.
What to check before you switch phones
A backup only restores if it is recent and complete. Before you move to a new phone, open WhatsApp on your old phone and go to Settings > Chats > Chat Backup (on iPhone) or Settings > Chats > Chat Backup (on Android). Look at the date next to "Last backed up". If it is more than a few days old, tap "Back Up to Google Drive" (Android) or "Back Up to iCloud" (iPhone) to create a fresh one.
Check your storage space on Google Drive or iCloud. A backup of thousands of messages with photos and videos can be 500 MB to several GB. On Android, go to Google Drive > Settings > Manage Storage to see how much space you have left. On iPhone, go to Settings > [Your Name] > iCloud > Manage Storage. If you are running low, delete old photos or videos from your phone first, then back up again.
Make sure you know your phone number and have access to the phone number you used to set up WhatsApp. WhatsApp sends a verification code to that number when you sign in on the new phone. If you are keeping the same number, this is automatic. If you are switching to a new number, you can change it in WhatsApp settings on your old phone before you move, or change it on the new phone after you restore.
Moving messages from iPhone to Android or Android to iPhone
WhatsApp does not offer a direct restore when you switch operating systems. Instead, you export your chats as text files and move them to the new phone. This method preserves the words in your messages but not the photos, videos, or voice notes — those require a separate process.
On iPhone: Open WhatsApp, go to Settings > Chats > Chat Backup. Tap "Export Chat" and choose which chats you want to export (you can do all of them or pick individual ones). WhatsApp creates a text file and offers to send it via email, Messages, or cloud storage. Send it to yourself or to an email account you can access on your new Android phone. The file is a plain text document with timestamps and names, but no media.
On Android: Open WhatsApp, go to Settings > Chats > Chat Backup > Export Chats. Choose which chats to export. Android creates a text file and lets you send it the same way. Again, this is text only.
Once you have the text files on your new phone, you can read them in any text editor or email app, but WhatsApp itself will not import them back into your chat history. Your new WhatsApp installation starts fresh with no message history. Some people keep the exported files as a record but accept that their new phone will not show old conversations in the app.
Moving photos and videos when switching operating systems
If you want to keep the media files (photos, videos, voice messages) from your old phone, you need to move them separately because WhatsApp does not include them in the text export.
On iPhone: Open the Files app or iCloud Drive. Navigate to WhatsApp > Media. You will see folders for Photos, Videos, and Voice Messages. Select the files you want to keep and either email them to yourself, upload them to Google Drive or Dropbox, or use AirDrop if you have another Apple device nearby. Then read them on your Android phone.
On Android: Open the Files app (or your phone's file manager). Navigate to WhatsApp > Media. You will see the same folders. Select the files and email them, upload them to Google Drive, or use a file-sharing app to move them to your new phone. Once they are on your Android phone, you can save them to your photo library or keep them in a folder for reference.
This process is manual and time-consuming if you have thousands of files. Many people choose to keep only the most important photos and videos, or accept that they will lose access to old media when they switch phones.
Why your backup is encrypted and what that means
WhatsApp uses end-to-end encryption for messages in transit (when they travel between phones) and for backups at rest (when they sit on Google Drive or iCloud). The encryption key lives on your phone, not on WhatsApp's servers or Google's or Apple's. This means WhatsApp staff, Google staff, and Apple staff cannot read your messages or your backup, even if they wanted to or were ordered to by a court.
The trade-off is that if you lose your phone and forget your Google or iCloud password, you cannot recover your backup. The encryption key is gone. This is why WhatsApp asks you to set a backup password (optional on Android, built into iCloud on iPhone) — it adds a second layer so that even if someone steals your Google or iCloud account, they still cannot read your WhatsApp backup without the password you set.
If you are concerned about someone accessing your backup, you can turn off automatic backups in WhatsApp settings and back up manually only when you choose to. You can also delete old backups from Google Drive or iCloud to reduce the amount of data stored there.
Frequently Asked Questions
What happens to my messages if I do not restore from backup?
They stay on your old phone. Your new phone starts with an empty WhatsApp. If you do not restore within a few weeks, Google Drive or iCloud may delete the backup automatically (timing varies by provider), so restore soon after you set up the new phone.
Can I restore a backup from one Google account to a different Google account?
No. The backup is linked to the Google account that created it. If you are switching Google accounts, you will need to export your chats as text files instead. The same applies to iCloud accounts on iPhone.
Will my backup include messages from group chats?
Yes. Group chats, one-on-one chats, and broadcast lists all restore from backup. You will rejoin the groups automatically when you restore, and you will see the full message history.
How long does a backup take to restore?
It depends on the size of your backup and your internet speed. Small backups (under 100 MB) usually restore in a few minutes. Large backups (over 1 GB) can take 30 minutes to an hour. Make sure you have a stable WiFi connection and do not close the app while it is restoring.
Can I back up WhatsApp to both Google Drive and iCloud at the same time?
No. Android phones back up to Google Drive only, and iPhones back up to iCloud only. You cannot use both services for the same WhatsApp account.
