Have you tried turning off iCloud drive on the phone in

Settings, your name, iCloud.

then in Files app make sure there are no files hanging around when you browse iCloud Drive.

Then restart the phone.

Thanks for getting back to us, felipeglima. The section in the article titled "Delete folders or files in iCloud Drive" is where you would want to check to see if there are more files than you expect there. If you can only see the files you expect, and they don't add to 10GB or what is showing in your iPhone, then we advise continuing with the steps below to rule out any errors on the iPhone causing the behavior:

1. Restart your iPhone
2. Update your iPhone, iPad, or iPod touch
3. Close an app on your iPhone or iPod touch (close the iCloud Drive app)

Once those steps are taken, please recheck the space allocations and let us know if that's cleared it. Also, make sure to consider other devices saving files to the Drive as well. Take care.
