How can you restore WhatsApp backup from Google Drive to iPhone?

Unfortunately, it's not possible to restore a WhatsApp backup from Google Drive directly to an iPhone because Google Drive is a service provided by Google, which is a competitor to Apple's iCloud service. WhatsApp backups created on Google Drive can only be restored on Android devices.

However, if you have previously backed up your WhatsApp chat history on iCloud, you can restore it on your iPhone by following these steps:

1. Uninstall WhatsApp from your iPhone.
2. Reinstall WhatsApp from the App Store.
3. Open WhatsApp and verify your phone number.
4. When prompted, tap "Restore Chat History" to restore your chats from iCloud.

If you don't have a backup of your WhatsApp chat history on iCloud, you won't be able to restore it on your iPhone. In this case, you can consider using a third-party tool or service to transfer your WhatsApp chat history from Google Drive to iCloud, but be aware that these tools may not always work as expected and may compromise the security and privacy of your data. It's recommended to always use official channels and services to transfer or backup your data.
