KGI Securities' Ming-Chi Kuo has said that he has found proof that the next iPhone's added thickness will have less to do with battery life or bendiness than making space for the Force Touch electronics that will be one the new phone's chief selling points.

Kuo's track record on Apple specs is pretty good. He got the iWatch spec right, and no one believed it would be THAT pointless. He also predicted that the iPhone 6s this fall will come in only two sizes: 4.7-inch and 5-inch.

For years now Apple has been marketing the fact that its phones have been getting thinner. Then with the iPhone 6 it suddenly realised that at a certain point they become structurally unsound.

Of course it did not tell anyone that. In fact it, at the Tame Apple Press denied that it was possible to bend the iPhone 6 despite lots of video's appearing on YouTube proving it.

Apple's senior vice president for marketing Phil Schiller told Daring Fireball  that thinness as a tradeoff and no longer a feature.

"If you want a product that's thicker with a bigger battery it's also heavier, more costly, takes longer to charge... We model every thickness, every size, every weight and try to figure out what the tradeoffs are. I think we've made great choices there."

Paraphrasing this means "we could not make it any thinner without making it flacid" we decided to market something else instead and hope no one noticed.
