Apple is ramping up on two bigger 
devices, said the people, who asked not to be identified because the 
plans are private. One model will have a 4.7-inch display, compared to 
the 4-inch screen of the current iPhone 5s, that may be available to 
ship to retailers around September, said two of the people. A 5.5-inch 
version is also being prepared for manufacturing and may be available at
 the same time, the people said.
The new iPhones 
will also be rounder and thinner than previous models, said one of the 
people. Production of the 5.5-inch model is more complicated than the 
smaller version, resulting in lower production efficiency that must be 
overcome before manufacturing volume can be increased, said the person.
Apple
 is getting ready for its annual unveiling of new iPhones after rivals 
including Samsung and HTC released smartphones with displays that are as
 large as 5.7 inches. Consumers have been gravitating toward 
larger-screen devices — in China, 40 percent of mobile gadgets based on 
Google's Android operating system that were sold in 2014 had display 
sizes of more than 5 inches, according to an estimate from Forrester 
Research.

Chief Executive Officer Tim Cook is under pressure to 
reignite Apple's sales growth and the iPhone, which generates more than 
half of the company's annual revenue, remains his chief weapon. Last 
year, the smartphone produced $91 billion in revenue alone, more than 
the total sales of Oracle, Yahoo, Facebook and Twitter combined.
Natalie Kerris, a spokeswoman for Cupertino, California- based Apple, declined to comment.
