The differences between the iPhone 4S and the iPhone 4 are not limited to the hardware, Siri and the camera, because apparently the loudspeaker of the new device has a greater power than the one implemented in the iPhone 4. clip above we have a short demonstration regarding the audio power of the two terminals and noticed that the 4S is the one that offers a clearer and stronger audio quality. The difference between the speaker power of the 2 devices seems to be about 6 decibels and I don't even think that a decibel measuring device was needed because the difference would have been obvious anyway.
The first terminal tested is the iPhone 4, the second is the iPhone 4S and for now we are finding out little by little what is hidden behind the case of the new device. Apple does not make any reference to this difference on its website, nor will you find any reference elsewhere, and many other minor changes could be hidden in the new terminal.
