What did you eyeball to get 2 GB? Remember the iOS can use up ~2 GB.
To be certain, on your iPhone go to Settings>General>Storage & iCloud Usage>(Storage)*Manage Storage and you will see a list of all the apps that are consuming some of your 12 GB. Some of them may allow you to trim down what they are consuming.
*Pick "Manage Storage" from the "Storage" portion, not the iCloud portion.
On a Mac since 1984.
Currently: 24" M1 iMac, M2 Pro Mac mini with 27" BenQ monitor, M2 Macbook Air, MacOS 14.x; iPhones, iPods (yes, still) and iPads.
