Just two months before the launch of the next iPhone (according to an advertisement available in China, Apple will launch the new smartphone on the 19 September but the date has not been officially confirmed) Apple has already commissioned the production of over 70 of millions of iPhone 6 units, both 4.7 and 5.5 inches, the deadline for completing this order being 30 December 2014.
It seems that Apple is expecting a fairly high failure rate in terms of production of the new smartphone, the company asking manufacturers to order a sufficient number of components for manufacturing 120 million units to ensure that between them between 70 and 80 million units will be functional. 4.7 inch model will be produced by Foxconn and Pegatron, companies that produced the earlier iPhone models, while 5.5 inch model will be manufactured by Hon Hai. Manufacturing process for the larger screen of the iPhone 6 (called in-cell technology) will be more complicated, touch sensors and will be integrated directly into the LCD, giving up the display to create a new layer, which will be covered with a sapphire crystal, though it is more expensive than glass, is more resistant and more durable.
Although not confirmed anything until now, rumors about us upgrades available on the iPhone 6 talk about a new camera optical image stabilization, outperforms the iPhone 5S, 128 GB storage space, slimmer than their predecessors, greater autonomy of the battery, RAM speeds and support for HD Voice. How many of these will become reality we are probably only after the launch of two iPhone models 6 hopefully in September this year.
