Among may rumors, one of them is about removing 3.5mm headphone port from iPhone 7 series devices. A twitter user reported that iOS 9.3 Beta 1.1 makes this rumor strong considering its coding, and also believe that newer model may not feature a headphone port.
So Apple may supply a wireless headphone along with iPhone 7 and later model. This rumor has gone wild when iPhone 6s water test showed a surprising result. Apple has not said anything about being water resistant of iPhone 6s, but it survived after a 30 mins of test. So iPhone 7 and 7 plus are also expected to be waterproof and dustproof.
The same Twitter user also shared the iOS 9.1 code informing that Apple is testing Li-Fi technology that can be used in iPhone 7. Li-Fi is also based on Wireless Technology, but it has the ability to provide higher speeds compared to Wi-Fi.
In case of iPhone 6s and 6s Plus, Apple has been criticized for Samsung vs TSMS Apple A9 Chip. Now there is rumor that TSMC would be the only manufacturer to Supply Apple A10 chip for iPhone 7 and 7 Plus.
Another rumor is about the physical home button that is expected to be removed. 3D display allows users to switch to different app by pressing on the edge of the display, and it can also be done by pressing physical home button twice, but that’s optional now. So the physical home button got just one primary task to do; work as Finger Print Scanner. So Apple may incorporate Finger Print Scanner within display, but this is not likely to happen this year.
However, have a look at the concept video of iPhone 7 made by iPhone-Tricks that shows the device without Physical Home Button
