Quick Answer
For same OS transfers (Android to Android or iPhone to iPhone), back up to Google Drive or iCloud on the old phone, install WhatsApp on the new phone, sign in with the same number, and choose Restore from backup.
For cross platform transfers (iPhone to Android or Android to iPhone), use Apple s Move to iOS app or the official WhatsApp transfer flow inside Samsung Smart Switch.
The newer wireless QR code transfer works between two devices on the same Wi Fi without any cloud step. Settings, Chats, Transfer chats, scan the code, done.
Before you start: must do prep
- Charge both phones to at least 50 percent or keep them on chargers.
- Connect both to the same Wi Fi network. Cellular data works but is far slower and costs you data.
- Make sure your phone number is portable to the new device. WhatsApp ties account identity to the number.
- Update WhatsApp on both phones to the latest version. Older versions can fail mid restore.
- Back up before you start. Even if you are using a wireless transfer, a fresh cloud backup is your insurance policy.
Method 1: Android to Android (Google Drive backup)
- On the old phone, open WhatsApp, tap the three dot menu, choose Settings, Chats, then Chat backup.
- Tap Back up and wait for the upload to finish. Include video if you want media restored.
- Install WhatsApp on the new phone from Google Play.
- Open WhatsApp, agree to terms, enter the same phone number, and verify by SMS or voice call.
- Sign in to the same Google account used for the backup.
- Tap Restore when prompted. Wait for chats and media to download.
Method 2: iPhone to iPhone (iCloud backup)
- On the old iPhone, open WhatsApp, tap Settings, Chats, Chat Backup, then Back Up Now.
- Make sure iCloud Drive is enabled and you have enough free iCloud storage.
- On the new iPhone, sign in to the same Apple ID used on the old phone.
- Install WhatsApp from the App Store, agree to terms, enter the same phone number, verify with SMS.
- When prompted, tap Restore Chat History.
Method 3: Wireless QR code transfer (same OS)
This 2023 era feature avoids the cloud entirely.
- Install WhatsApp on the new phone.
- Open WhatsApp, agree to terms, enter the same number, and verify.
- When the app prompts to transfer, tap Start.
- On the old phone, go to Settings, Chats, Transfer chats, then scan the QR code shown on the new phone.
- Keep both phones unlocked and on the same Wi Fi until the transfer completes.
Best for: avoiding cloud storage limits, transferring multi GB media archives quickly.
Method 4: iPhone to Android (cross platform)
This requires Android 12 or later and a brand new or factory reset Android device.
- On the iPhone, install Move to iOS...wait, the reverse: download Samsung Smart Switch on the new Galaxy, or use the built in Move to Android flow during initial setup on a Pixel.
- Connect the iPhone to the Android with the included USB C to Lightning cable.
- When prompted, open the WhatsApp transfer step.
- Sign in to WhatsApp on the iPhone, follow the on screen QR code, and authorise the transfer.
- Complete the Android setup, then install WhatsApp on the Android, verify your number, and import the transferred chat history.
Method 5: Android to iPhone (cross platform)
- On the new iPhone, during initial setup choose Move Data from Android.
- On the Android, install Apple s Move to iOS app from Google Play.
- Connect both devices to the same Wi Fi.
- Follow the iPhone s on screen instructions; a six digit code links the devices.
- Choose to transfer WhatsApp data along with contacts, photos, and other content.
- After setup, install WhatsApp on the iPhone, verify your number, and import the transferred chats.
What does and does not transfer
- Transferred: all chats, group memberships, media, voice notes, starred messages, and profile photo.
- Not transferred: call history and your WhatsApp display name only (you set it again on the new device).
- End to end encrypted backups: if you enabled the 64 digit encryption key, you must enter it on the new phone before the restore can begin. Do not skip writing this key down before changing devices.
Troubleshooting
- Restore stalls at 99 percent: usually a weak Wi Fi connection. Move closer to the router and retry.
- Backup not found: double check that the Google account or Apple ID on the new phone matches the one that created the backup.
- Verification SMS not arriving: use the Call me option, or wait 10 minutes and try again. Carrier delays are common during number ports.
- Old phone shows registered to another device: WhatsApp is single device per number for the primary account. Once activated on the new phone, the old phone is logged out.
FAQs
Will my chats stay encrypted during the transfer?
Yes. All transfer methods preserve end to end encryption. Backups are also encrypted if you turned that on under Settings, Chats, Chat backup, End to end encrypted backup.
Can I keep WhatsApp running on the old phone?
No, not for the same phone number on the same account. Use WhatsApp s linked devices feature to keep your tablet or laptop signed in alongside the new phone.
How long does the transfer take?
Small accounts (under 1 GB) finish in 5 to 10 minutes. Large accounts with years of video can take 30 to 90 minutes. Keep both phones unlocked the entire time.
What if I lose my phone before transferring?
If you have a recent cloud backup, install WhatsApp on the replacement device, verify the same number, and restore from cloud. Without a backup, chats are lost; WhatsApp cannot recover them.
The takeaway
Back up first, match the cloud account on both sides, and let the official WhatsApp transfer flow do the work. The wireless QR code transfer is the cleanest option for same OS moves, and the official cross platform tools now handle iPhone to Android without third party hacks.
