Switching phones is exciting until you realize your WhatsApp history is still on the old one. Years of chats, photos, and voice notes live inside the app, and they do not move by themselves. A backup made before the switch carries all of it to the new phone in minutes.
WhatsApp backup works differently on Android and iPhone, and the two systems do not share backups with each other. This guide covers both paths, plus the media and storage details that catch people out at the last moment.

How WhatsApp Backup Works
WhatsApp stores your chat history in a backup file, separate from the app itself. On Android, that file goes to Google Drive. On iPhone, it goes to iCloud.
The backup includes messages, and it can include:
- Photos
- Videos
- Voice notes if you choose
Media makes the backup much larger, so the backup settings let you leave videos out. Text-only backups are small and fast, while full media backups can take a long time on slow Wi-Fi.
Backups are tied to your phone number and your cloud account. You must use the same phone number and the same Google or Apple account on the new phone. A different number or account means the new phone cannot find the backup at all.
Backing Up on Android
Open WhatsApp, go to Settings, then Chats, then Chat backup. Choose the Google account for the backup, and tap Back Up to start a manual backup right now. Do not rely on the automatic schedule alone, because the last automatic backup may be days old.
Decide whether to include videos before you start. Videos are the largest part of most backups, and leaving them out can turn a two-hour backup into a ten-minute one. If the videos matter, include them and run the backup overnight on Wi-Fi.
Check the backup size and the date shown on the same screen when it finishes. The date must be today, and the size should look plausible for your chat history. A backup that reports zero or a tiny size means something failed, so run it again before you touch the old phone.
Backing Up on iPhone
On iPhone, open WhatsApp, go to Settings, then Chats, then Chat Backup, and tap Back Up Now. WhatsApp uploads the backup to iCloud, and the same screen shows the date and size of the last backup. Make sure iCloud Drive is turned on in the iPhone settings, or the backup will fail silently.
iPhone backups also let you exclude videos, and the same advice applies. Videos bloat the backup and eat into your iCloud storage, and many people keep their important videos in the camera roll anyway. Exclude videos unless you know you need them in WhatsApp itself.
Watch your iCloud storage before you start. A full iCloud account stops the backup partway through, and WhatsApp may not warn you clearly. Free up space or buy a month of extra storage if the backup size is close to your remaining iCloud space.
If the backup stalls, check the Google account storage before you retry. A full Google account stops the upload silently, and freeing space or removing old Drive files lets the backup finish. The backup screen shows the account and the used space, so the cause is easy to spot.
Moving Between Android and iPhone
Moving between Android and iPhone needs a transfer, not a backup, because Google Drive and iCloud backups do not cross over. WhatsApp offers a built-in transfer that moves chats directly from one phone to the other during setup. Both phones must be nearby and connected to the same Wi-Fi network.
On Android to iPhone, start the Move to iOS app on the Android phone during iPhone setup, and choose WhatsApp when it asks what to transfer. On iPhone to Android, connect the phones with a cable during Android setup and choose WhatsApp in the transfer options.
Do the transfer before you start chatting on the new phone. New messages sent on the new phone before the transfer will be overwritten by the restored history. Set up the transfer first, then send your first message from the new phone.
Verifying the Restore on the New Phone
Install WhatsApp on the new phone, verify the same number, and accept the restore prompt when it appears. The restore downloads the backup and rebuilds your chat list, which can take several minutes for a large backup. Keep the app open and the phone on Wi-Fi until it finishes.
Open a few old chats and check that photos and voice notes are there. Text usually restores first, and media follows in the background. If photos show as grey boxes, wait a few minutes and check again before concluding the restore failed.
Keep the old phone untouched for a day after the switch. If something is missing, the old phone still has the original chats, and you can run a fresh backup and restore again. Wipe the old phone only after you are sure everything arrived safely.
A second backup costs little and removes the risk entirely. Copy the phone chat database to a computer with a USB cable before the switch, and keep it until the new phone is verified. Two copies mean one failure never loses a conversation.
