Just to keep track of similarities and differences for my working device, I use argon2id also, with settings m=256, t=2, p=3. On a check right now, available RAM on my iPad and iPhone are similar, about 185GB. Working RAM on an iPhone 15 Pro is 8 GB while the older iPad has 6GB. Currently I have enabled biometrics.
Anything else anyone dreams up for me to check or compare, let me know.
An earlier version of this post said I had PIN enabled also. That was incorrect.
