Apple's upcoming iPhone 6 is soon to be released around September 2014 and new developments have also leaked from a schematic in China. It reveals two variants of iPhone 6 having 4.7 and 5.5 inch models with higher resolution implicating new upgrade cycles.

New Schematics from China

French Web site Nowhereelse caught a copy of iPhone 6 schematics from China and it reveals the dimensions of two variants having larger screen displays compared to iPhone 5S and previous iPhone models.

1. iPhone Phablet - Measures 150 mm long with wideness of 85 mm which is bigger compared to 123 mm and 58.6 mm of the current iPhone 5S. If compared, it has a similar size with Samsung Galaxy Note 3 having 5.7-inch display. Schematic also revealed at least 5 inches of screen dimension diagonally.

2. iPhone Handset - Probably the flagship release which features 4.7-inch display screen contrast to the 5.5-inch phablet variant.

New schematics from China remain rumoured information and even though it has the Apple logo and affix designs for iPhone devices, there is no way to tell for sure if real or another fake documentation leaking online.

Mother lode and Upgrade Cycle

iPhone 6 4.7 inch and 5.5 inch models are going to become the new mother lode of upgrade cycles for Apple's smartphone pride starting in 2014. Brian Marshall at ISI tipped out that having larger screen displays for iPhone will bring bigger sales from existing customers and even attract those device users of Android or Windows Phone.

"Large-screen envy is prevalent among the iPhone installed base and we believe a 5 inch form factor iPhone would spark a massive upgrade cycle as well as many Android switchers returning back to the iPhone," said by ISI according to Business Insider.

With the growing competition among smartphones, iPhone 5S looks smaller and cramped compared with HTC One M8, Samsung Galaxy S5 and Sony Xperia Z2 having at least five inches of screen display.

Moreover, Samsung's foundation on phablet devices called Galaxy Note features more than just bigger screens but also unique functions using the S Pen for live editing, multimedia and office related tasks.

According to Nikkei, iPhones having larger screen display will also come with higher display resolution and probably at least 1080p full HD if not 2K.

The iPhone 6 is expected to be released around September 2014 and will run the upcoming new iOS version 8 which may appear at Apple Worldwide Developers Conference starting from June 10th to 14th.
