Apple CEO Tim Cook has said that the company won't be launching a bigger iPhone until building one doesn't require any 'trade-offs' in order to accommodate a larger display. 

Speaking at Apple's quarterly earnings call on Tuesday, Cook said: "My view continues to be that the iPhone 5 has the absolute best display in the industry. We always strive to create the very best display for our customers."

"Some customers value large screen size, others value also other factors, such as resolution, colour quality, white balance, brightness, reflectivity, screen longevity, power consumption, portability, compatibility apps, many things," he continued.

"Our competitors have made some significant trade-offs in many of these areas in order to ship a larger display," Cook said. "We would not ship a larger-display iPhone while these trade-offs exist."

 

So, while Cook hasn't ruled out a bigger iPhone completely, it looks like we won't be seeing one any time soon, despite rumours that a 4.8in iPhone could launch this year.

Earlier this year, Barclay's Capital analyst Ben Reitzes said that Apple should launch a bigger iPhone, which he dubs 'iPhablet', because he expects the larger phone market to dominate smartphone shipment growth into 2015.

Apple's iPhone 5 has 4in screen, which is already bigger than the 3.5in display found in previous models, but many competing smartphones are launching with even bigger screens.

Apple rival Samsung's upcoming Galaxy S4, which is said to be released on 27 April, has a 5in display, while the company's new Galaxy Mega has a 6.3in display.

On Tuesday, Cook did reveal that Apple is working on "amazing" new products for an autumn launch, with "exciting new product categories" coming in 2014.
