Your iPhone is, as well as software updates (new versions of iOS), receiving regular firmware updates.

But there is another layer in most devices and that is firmware, partway between hardware and software there is firmware, neither hard nor soft. Firmware are chips which act like hardware but their code is adaptable. And that’s what happens when the manufacturer updates the capabilities of the device, as part of the package you get software but you also get firmware.
