The new iPhone 13 Pro Max with a Terabyte of storage still only has USB 2.0 on its sole lightning port. If we assume only 5% overhead /error correction on the entire transfer, that would take over 5 hours to transfer or backup the device.

Might be faster even with additional overhead to transfer wirelessly

Airdrop uses Bluetooth 4.0 to setup an adhoc (peer to peer) Wifi connection. In theory it should be a gigabit per second or so. I have never seen speeds like that though. 802.11ax <----> WiFi 6
