There's a lower limit to the length of a phone and still have the capability of a phone which is the mean distance between peoples' ears and mouths. You also can't make a phone too small or else the screen won't be readable. Even if you could get the iPhone 15's electronics to fit a chip the size of a grain of rice the body of the phone needs to fit a head and needs a screen for an interface. The antenna would still need to be sized such to be tuned for the right cellular frequencies. That's not to say candy bar phones are the perfect form factor. It's just ergonomics and physics will play a part in devices no matter how compact the technology.
