iPhone 12 iPhone erase data duration

[MaiKAimer]

I am about to trade in my old iPhone 12 so I decided to erase all settings and >60GB content on the phone. I followed the instructions in settings and clicked Erase iPhone.

The white Apple logo appeared and the whole erasing process finished in like, 1-2 minutes? After this super short period of time the "Hello" set up screen appeared.

Is it even normal that a full erase finishes this quick? Are my data securely erased?

Any advice would be appreciated.

Your data isn't technically erased in the traditional sense. All your data is stored encrypted and your key is in the Secure Enclave. When you erase your phone, the key is destroyed so your data cannot be decrypted. This is why it's so quick.
