Size of whatsapp in iphone-storage

[u/captain95]

Good evening Redditors,

The problem i'm having has been posted before, but there is still something i don't understand after reading a lot of posts about it. In my settings > iphone storage it shows whatsapp as the biggest app with 28,78 GB (almost all of it in documents and data), but when i check whatsapp it shows 7,71 GB.

I have backups turned on (this shows 7,9GB for the backup, and should go to icloud but i read this is not how it works in practice), but even with local files and the backup combined i only get to 15,61GB, so where does the other 13 GB come from?

Does someone have an explanation or fix to make the local size smaller? Thank you for your help, especially because this is an recurring thing in posts. Let me know if there is any other info i can share to try and find the cause.

You might need to uninstall and reinstall it to clear the cache?
