New Rumor Suggests iPhone 7 Won't Include Smart Connector After All
The Smart Connector, first introduced with the iPad Pro, is a new type of port designed to transfer both data and power between the iPad Pro and accessories like the Smart Keyboard. It's never been clear what purpose a Smart Connector would serve on an iPhone, but speculation ranged from battery cases to wireless charging.
Hints that a Smart Connector would be included on the iPhone 7 and iPhone 7 Plus first surfaced in an image said to be of the iPhone 7 Plus shared by a Chinese website in March. It is still not clear whether that image depicts an actual iPhone 7 device, a mockup based on design schematics, or a counterfeit device. A Smart Connector was also depicted in design drawings created by Mac Fan, but those drawings are often largely based on circulating rumors.
Mac Otakara suggests Apple decided to shelve the Smart Connector after considering it as an included feature, but given the questionable nature of the original rumor, it's possible a Smart Connector was never planned for the device. Rumors about the iPhone 7 are still uncertain with a lot of conflicting information surfacing, so the final design and features of the device continue to be up in the air.
Rumors have disagreed on features like waterproofing, the removal of the headphone jack, the thickness of the iPhone 7, stereo speakers, whether the camera will protrude, and more, but it's likely a clearer picture of the iPhone 7 will emerge in the months leading up to its prospective fall release.
