The fastest way: back up to Google Drive or iCloud before you switch

WhatsApp stores your message history on your phone, not in the cloud by default. To move everything to a new phone, you back up your chats first, then restore them on the new device. The backup lives in Google Drive (Android) or iCloud (iPhone) — services you may already use for photos and documents.

The process takes about 10 minutes if your backup is current, and you do not lose any messages, photos, or voice notes from your chats. If you do not back up before switching phones, those conversations are gone.

The steps differ slightly between Android and iPhone, and between moving within the same operating system versus switching from one to the other. The key is doing the backup on your old phone before you set up the new one.

Key Takeaways

  • Back up WhatsApp on your old phone to Google Drive (Android) or iCloud (iPhone) before you get a new device.
  • On Android, go to Settings > Chats > Chat backup and tap "Back up to Google Drive" — choose which Google account and how often.
  • On iPhone, go to Settings > Chats > Chat Backup and tap "Back Up to iCloud" — you need an iCloud account with enough free space.
  • After you sign into WhatsApp on your new phone with the same phone number, the app will find your backup and ask if you want to restore it.
  • If you switch from iPhone to Android or Android to iPhone, you cannot transfer your backup directly — you will need to use a third-party tool or accept starting fresh.

Android: backing up to Google Drive

Open WhatsApp and tap the three dots in the top right corner. Go to Settings > Chats > Chat backup. You will see "Back up to Google Drive" with a button that says "Back up." Tap it.

WhatsApp will ask you to choose which Google account to use — pick the one you use most often, because you will need to sign into that same account on your new phone. Then choose how often you want automatic backups: daily, weekly, or monthly. Daily is safest if you use WhatsApp a lot. Tap "Back up" again to start the backup right now.

The backup includes all your chats, photos, videos, voice messages, and call logs. It does not include your profile photo or status updates — those are tied to your phone number and will reappear when you sign in on the new phone. The backup size depends on how many messages you have; most people's backups are between 50 megabytes and a few gigabytes.

iPhone: backing up to iCloud

Open WhatsApp and tap Settings in the bottom right. Go to Chats > Chat Backup. You will see "Back Up to iCloud" with a toggle switch. Turn it on.

WhatsApp will ask you to sign into your iCloud account if you are not already signed in. Make sure you have at least as much free iCloud storage as your backup will need — you can check this in Settings > [Your Name] > iCloud > Manage Storage. If you do not have enough space, you can buy more iCloud storage (50 gigabytes for $0.99 per month) or delete old photos and videos to free up room.

Once iCloud backup is on, WhatsApp backs up automatically every night at 1 a.m. if your phone is plugged in and connected to Wi-Fi. You can also tap "Back Up Now" to start a backup when ready. The backup includes all your chats, photos, videos, voice messages, and call logs.

Restoring your chats on the new phone

When you set up WhatsApp on your new phone, use the same phone number you used on the old phone. WhatsApp will recognize that you have a backup and ask if you want to restore it. Tap "Restore" and wait for the process to finish — this can take a few minutes if you have a lot of messages.

Your chats, photos, and messages will appear in the order they were on your old phone. Your contact list and groups will also restore. Anything you sent or received after the backup was created will not be there — so if you back up on Monday and switch phones on Friday, messages from Tuesday through Friday are lost.

For this reason, back up as close to the moment you switch phones as possible. If you are keeping your old phone for a few days, you can do a second backup on the new phone once you have restored the first one, but WhatsApp does not let you merge two backups — the second one overwrites the first.

Switching from iPhone to Android or Android to iPhone

WhatsApp backups are not compatible across operating systems. An iCloud backup cannot restore to Android, and a Google Drive backup cannot restore to iPhone. If you are switching from one system to the other, you have two options: use a third-party migration tool, or start fresh with a new chat history.

Third-party tools like Samsung Smart Switch (for Samsung phones) or specialized apps can sometimes transfer WhatsApp data between systems, but they are not made by WhatsApp and do not always work perfectly. They cost money and require technical steps that are straightforward to get wrong. Many people find it simpler to accept that they will lose their old chat history and start fresh on the new phone.

If you want to keep important conversations, you can screenshot them or forward key messages to yourself before you switch. Some people also use WhatsApp's "Export Chat" feature (available on both Android and iPhone) to save individual conversations as text files, though this does not preserve photos or videos.

What happens if you do not back up

If you switch phones without backing up, your WhatsApp messages are gone. WhatsApp stores chats on your phone's internal storage, not on WhatsApp's servers. Once you sign into WhatsApp on a new phone, the app creates a new, empty chat history.

You cannot recover deleted messages unless you have a backup. WhatsApp does not keep a copy of your chats on its servers for you to retrieve later. This is actually a privacy feature — it means WhatsApp itself cannot read your messages — but it also means you are responsible for backing them up.

Common mistakes that lose your messages

The most common mistake is backing up to the wrong account. If you back up to one Google account on your old phone, but sign into a different Google account on your new phone, the backup will not be found. Write down which account you used before you switch phones.

The second mistake is not leaving enough time for the backup to finish. If you back up and then when ready turn off your old phone, the backup may not complete. Wait at least five minutes after you tap "Back up" before you power down.

The third mistake is signing into WhatsApp on the new phone with a different phone number. WhatsApp ties your account to your phone number. If you use a new number on the new phone, WhatsApp treats it as a new account and will not find your old backup. If you are changing phone numbers, you can transfer your WhatsApp account through WhatsApp's "Change Number" feature in Settings > Account > Change Number before you switch phones.

Frequently Asked Questions

Can I back up WhatsApp while I am using it?

Yes. You can use WhatsApp normally while a backup is running in the background. The backup does not interrupt your chats or calls. However, any messages you send or receive after the backup starts will not be included in that backup — they will be included in the next one.

How much does it cost to back up WhatsApp?

Backing up to Google Drive or iCloud is free if you have free storage space available. Most people have enough free space (Google gives 15 gigabytes free, Apple gives 5 gigabytes free). If you run out of free space, you can buy more, but the backup itself does not cost anything.

What if my backup is too old?

If your last backup is several weeks old, you will lose all messages from that point forward. You can create a new backup right before you switch phones to capture recent messages. On Android, tap "Back up" in the Chat backup settings. On iPhone, tap "Back Up Now" in Chat Backup settings.

Will my WhatsApp groups restore?

Yes. All your groups, group chats, and group members restore with your backup. You will rejoin the groups automatically when you restore. However, you will not receive messages that were sent to the group while you were switching phones.

Can I restore a backup to multiple phones?

No. Each WhatsApp account is tied to one phone number, and you can only have WhatsApp active on one phone at a time with that number. If you restore a backup to a second phone, WhatsApp will deactivate on the first phone. You cannot use the same account on two phones simultaneously.
