Just a few days back, I had posted an article on upcoming Apple iphones in 2013. Apple is planning to launch three iPhones this year. One of them being iPhone 5S. As per a recent report published on iLounge, Apple's new iPhone 5S will have new features like snappier processor, fingerprint sensor, better camera and more powerful LED flash. In 2012, Apple had acquired Authentec, one of the dealers of fingerprint sensor technology.

Apple iPhone 5S and other likely upcoming cheaper iPhones from Apple will be very much like iPhone 5 with little modifications. These phones will have a plastic casing and measure 8.2mm around the sides which is different than the present iPhone 5 which has aluminium body and waistline of 7.6mm. Also, these new phones will come in atleast 6 colors something which we have never seen till date from Apple. Regarding camera, the upcoming phone may have Sony's 13MP unit and two prototypes under development are named N51 and N53.

Well, I think we will have to wait and watch before these things turn out to be real. No doubt, Apple has been facing low demand for iPhone 5 to which CEO Tim Cook quoted - 
The supply chain is very complex and we have multiple sources for things. Yields can vary, supplier performance can vary. There is an inordinate long list of things that can make any single data point not a great proxy for what is going on. 

Hope things will get much better for Apple with these new developments..!
