Many may think talking about the iPhone 7 barely days after the release of iPhone 6s and iPhone 6s Plus is weird but that's what technology industry works, as planning for a big device starts pretty early. It is reported that Apple has started working on its future flagship smartphone which is much superior than its predecessor in terms of specifications.

Apple is expected to release its upcoming device dubbed as the iPhone 7 in September 2016. The company rarely reveals release date of its devices but it has the tradition of unveiling its flagship smartphone after its predecessor completes a year cycle in the market.

It is reported that Apple has a big plan for its iPhone 7 -- much bigger than the recently released iPhone 6s.

Here are expected specifications of the iPhone 7:

Display: Apple's upcoming smartphone is expected to be as thin as the iPod Touch and iPad Air 2. According to DigiTimes, analyst Ming-Chi Kuo of KGI Securities has said in a note to investors that thickness of the future iPhone, possibly iPhone 7, will be between 6.0 and 6.5 mm.

Processor: The iPhone 6s is powered by A9 chip but Geek has reported that Apple has started "placing orders for iPhone 7 parts" and mass production of A10 chip may begin in March 2016 with Taiwan Semiconductor Manufacturing Company (TSMC) securing exclusive supply contract.

Camera: The iPhone 7 is likely to come with a camera much superior to its predecessors. According to Business Insider, a source close to Apple's supply chain has said that the company is ordering six-element lenses for its future iPhone, perhaps iPhone 7. The iPhone 6s has five-element lenses.

According to a report by PCAdvisor, the iPhone could come with a price tag of £539 for 16GB version, £619 for 64GB, and £699 for the 128GB. However, it is just guess work after considering Apple's pricing of its devices in the last few years.
