Apple iPhone 7 rumours continue to emerge, revealing key details about the upcoming flagship's specifications and release date. A recent leak suggested Apple won't include the industry-standard 3.5mm headphone jack in its iPhone 7, which has been one of the most persistent rumours about the new iPhone.

Rumours of Apple ditching the 3.5mm headphone jack in iPhone 7 have been doing rounds for a while now, but a recent investigation into the iOS 9 source code seems to confirm that will indeed be the case. iOS jailbreaker @kyoufujibaya discovered a reference in Apple's recent iOS 9.3 beta, which states "'Headphones.have.%sinput.NO.", linking it to ongoing rumours.

Apple hasn't revealed any plan that confirms the rumours. Apple iPhone 7 is not due till September, which is usually when the Cupertino-based tech titan launches flagship iPhones of the year. Like last year, two iPhones — iPhone 7 and iPhone 7 Plus — are expected to be launched later this year.

Several rumours about possible specs and features of the upcoming iPhones have emerged in recent months. Reports about a jack-less iPhone 7 have sparked outrage among Apple fans, who went ahead and started an online petition to stop Apple from proceeding with the change.

If the new iPhone 7 comes without a headphone jack, Apple is rumoured to introduce new Bluetooth earphones or set up a connection via Lightning port, which will render the existing headphones useless. A headphone adapter may resolve the issue, but it will become a challenge if users wish to listen to music while charging the device.

The iOS 9.3 beta software code also revealed an interesting addition in the new iPhone. According to the jailbreaker @kyoufujibaya, Apple will integrate new Li-Fi technology in the iPhone 7 that will make wireless transfer speeds much faster. Li-Fi is said to be 100 times faster and transfers more data at extreme speeds compared to Wi-Fi.

Other possible changes expected in the iPhone 7 include a waterproof and dustproof design, larger battery, 3GB RAM, slimmer body, dual-camera zoom lens, a 256GB variant and a new A10 chipset.
