According to the official information from Apple this function will be available only on iPhone 6s, iPhone 6s Plus, iPhone SE, iPhone 7 and iPhone 7 Plus. Workers from Cupertino did not disclose the reasons for such a significant limitation, however, journalists and experts have their own opinions on this subject.
It is possible that such limitation took place due to the presence of the M9 (and the newer ones) coprocessor built directly into the Apple A9 chip. This processor is built-in only in iPhone 6s, iPhone 6s Plus, iPhone SE, iPhone 7 and iPhone 7 Plus. Thanks to it, Siri digital assistant is always active on Apple smartphones of the current generation.
