How do I recover the whatsapp chat data deleted from icloud?

I assume if you go to Settings > Your Name > iCloud that you A) have iCloud Drive enabled, and B) it's showing at least 40GB+ of current iCloud Drive usage (not "iCloud usage, but "iCloud Drive" usage specifically)?

Here is there official guidance:

https://faq.whatsapp.com/iphone/chats/how-to-restore-your-chat-history

They say you are supposed to have over 2x available free space? To me this makes no sense (?), but that would imply you need 80GB free to restore your 40GB backup? Do you have a 128GB or larger iPhone? Or only 64GB or 32GB?

Here is my idea for you:

1. Make a backup of your iPhone to a computer (Mac or Windows PC using iTunes for Windows) using a USB cable. [if possible]
2. Turn off Find My iPhone.
3. Go to Settings > General > Reset > Erase All Content & Settings.
4. When your iPhone restarts do not sign into your Apple ID. Just skip/don't sign in and set it up as a new iPhone so you can get to your home screen and keeping your iPhone completely empty.
5. Then go to Settings > Your Name and sign into your Apple ID but leave OFF all iCloud settings off EXCEPT for "iCloud Drive". You must have "iCloud Drive" turned on. Make sure you are signed into "Media & Purchases" (or iTunes and App Store, same thing) with your Apple ID.
6. Reinstall WhatsApp from the App Store and see if you can now restore your WhatsApp backup on iCloud Drive.

From what I can see this is your absolutely best chance. Please update here though and let me know if this works or not, and let me know if you have other data (and what kind) that you really care about or not (mostly referring to app-specific data).

yes please help.. i am still waiting for help or miracle for my whatsapp!! i reset my all settings & content many time but its showing the same error of "couldn't restore chat history". please help!

If you deleted the backup that the WhatsApp data was on, then it cannot be recovered.

I want to restore my WhatsApp data but every time its showing this message "couldn't restore chat history' I’m restoring the as per the instructions but it’s showing same error, “Couldn’t Restored Chat History”. I have 40+ GB backup of WhatsApp please help to resolve this issue or error.

no i am using same phone & same sim but its E-sim!

Actually i resent my phone because i forgot my passcode all my data has recovered / restored expect my 40gb whatsapp data.

WhatsApp uses iCloud Drive to store its data, but it uses its own encryption key tied to the phone number and SIM card that created the backup. Has your phone number changed? Has your SIM card changed?

So it just appears then that things are messed up with no particular good cause. My best suggestion would be looking at data recovery software for PC or Mac that is designed to pull the encrypted WhatsApp data store from your iCloud Drive. For example, I do see there is this one: https://www.elcomsoft.com/exwa.html although I would imagine there are others.

See, I have lot space empty but I still stuck in to restore the WhatsApp.

oooh hi, it happend to me too.. please lemme know if you already fix it
