The recently-discovered iPhone 7 Pro is of the same size as iPhone 7 Plus but features dual rear cameras and a magnetic connector on its back. It may also feature stronger specifications than iPhone 7 Plus but that is not a confirmed fact as of now.
iPhone 7: Definitely maybe!
What we know as of now about the upcoming iPhones is that they will feature redesigned antenna lines as well as significant internal improvements which should bring their benchmark scores closer to existing flagships like Samsung Galaxy S7 and HTC 10.
As per 9to5Mac, apart from featuring dual cameras, redesigned antenna lines and a very similar design as iPhone 6s, iPhone 7 and 7 Plus may also feature capable A10 chips with faster CPUs and GPUs, 3GB of RAM, storage option of 256GB and will be the first iPhones to be completely waterproof. In terms of camera setup, a leaked image of a rear case of the upcoming iPhone 7 Plus suggested that the phablet may feature dual rear cameras.
iPhone 7 to launch with 32GB as base storage: WSJ
The Wall Street Journal recently revealed that Apple will keep 32GB as the base storage in iPhone 7 and will also launch 64GB and 256GB variants for those with high storage requirements. The report also said that iPhone 7 will not feature a 3.5mm headphone port, will be thinner and water resistant and will feature 'substantial camera improvements.'
Macotakara, a Japanese tech news website, has also reported that Apple may not include the 3.5mm headphone jack in iPhone 7 but will ship the handset with 3.5mm ear pods with lightning adapters. 'At Computex Taipei 2016, many manufacturers showcased their new Lightning audio adaptors, and it seems there has been rumors that the EarPods with Remote and Mic to be included with the new iPhone 7 series will still come with its own headphone jack as usual, and that a Lightning headphone jack adaptor will also be included in the package,' said the website.
