Leaks leading up to the release of Apple's iPhone 7 can be interesting as well as confusing because of the contradictory claims made by various sources. It's now being reported that the upcoming flagship smartphone will have the same dimension as that of the iPhone 6s.

The Cupertino giant's next-generation smartphone will come with the same height and width as that of its predecessor, the iPhone 6s, Apple Insider reported, quoting Japanese blog Mac Otakara. It may be mentioned that the current flagship device has a dimension of 138.3 x 67.1 x 7.1 mm.

However, this report is in complete contrast with the claim made by Analyst Ming-Chi Kuo of KGI Securities (via DigiTimes) in a note to investors that Apple is planning to make its upcoming iPhone, possibly the iPhone 7, between 6.0 mm and 6.5 mm thick.

Mac Otakara also claimed the iPhone 7 will not have a new waterproofing as reported earlier but come with the same water resistance features seen in the current flagship device.

Apple fans will love to see a slimmer iPhone 7 with waterproofing feature, but they will be in for a disappointment if these features are not seen in the device when it is launched.

Apple is expected to release two variants of iPhone – iPhone 7 with a 4.7-inch display and iPhone 7 Plus with a 5.5-inch display. According to KGI analyst Ming-Chi Kuo's note to investors obtained by Apple Insider, one variant will house a single camera, while the other have a dual-camera with optical image stabilisation and zoom. He went on to say that Apple had to scrub its plan to incorporate the dual-camera technology in the iPhone 6s due to technical issues.

According to reports that have surfaced so far, the upcoming iPhone 7 will be powered by an A10 chip, come packed with 2/3GB RAM, and has features like sapphire glass, waterproof and wireless charger. It is also reported that the company's iconic Home button will be discarded in the upcoming next-generation device.

Apple is expected to release the next-generation device along with its bigger sibling, the iPhone 7 Plus, in September this year, by the time the iPhone 6s completes a year-cycle in the market.
