That's how we both (me and the iPhone iOS tech) came to the conclusion as we are accountable for data destruction on all smart devices, because we can't DBAN an iPhone. The chances of that happening is pretty nil. So unless you have a death wish against the NSA, 5 eyes, 9 eyes and 14 eyes spy agencies, no one would really be inclined to see what's in any soccer mom's former iPhone. We used to have a client and she was an investigative reporter to expose the 5 eyes secrets and not only her iPhone and Macbook got hacked through breaking crypto (they managed to get the keys) and compromised her security and work and threats to her own and family. The tools available are used to recreate the cypher keys necessary to access the data, but this is HARDER than you think and you really need heavy duty computing power which only government agencies possess like the NSA or the 5 eyes, 9 eyes and 14 eyes agencies also possess. So when you reset an iPhone, you are essentially destroying the cypher keys necessary to access the user data.

Important: Don’t use the “Erase all content and settings” option until device has been backed up, as there is no way to recover the erased data.' Therefore, it’s an ideal way to be sure all personal information is removed from a device before giving it to somebody else or returning it for service. The “Erase all content and settings” option in Settings obliterates all the keys in Effaceable Storage, rendering all user data on the device cryptographically inaccessible. Since you can't do that for iPhones, all you can do is to de-authorize the AppleID on the iPhone (we asked the donor to do this prior to dropping off their old phones) and then we reset them according to iOS security recommendation.
