The iPhone 5S and iPhone 5C may be little more than one month old, but that hasn't stopped rumours of the next iPhone, dubbed iPhone 6, from surfacing on the web. Reiterating whispers from earlier this year, a new report claims that Apple is working on a bigger iPhone ready for a September 2014 launch.

Macotakara has summarised a report published in Japanese magazine Mac Fan, which claims that Apple will be shipping an iPhone 6 in September 2014 with a 1920 by 1080 pixel 5in 440ppi display. The iPhone 5s has a 4in display with a resolution of 1136x640 at 326ppi.

The report suggests that the iPhone 6 could be promoted by Apple as the first device in the 'phablet' category that can be operated using one hand, thanks to side bezels that are "as thin as possible."

Talk of a bigger iPhone has been circulating for a while now, but there has been some doubt about whether such device is actually in the pipeline following comments from Apple in April.

CEO Tim Cook said during an earnings call earlier this year that the company wouldn't ship a bigger iPhone while trade-offs such as resolution, colour quality, white balance, brightness, reflectivity, screen longevity, power consumption, portability and app compatibility.

However, Cook didn't rule out the iPhone completely. Perhaps Apple has figured out ways to avoid these trade-offs, and has therefore decided to increase the size of the iPhone.

Several analysts certainly seem to think Apple is working to make the screen size of the iPhone bigger. In September, KGI securities analyst Ming-Chi Kuo said that Apple is likely to launch an iPhone with a 4.5in or 5in screen next year, noting that Apple is unlikely to go bigger than 5in because of its "unwavering principle of one handed use."

Also in September, Cantor Fitzgerald analyst Brian White said that Apple would launch a "Mega iPhone" in 2014 to expand its reach in China and the rest of Asia, and reiterated his prediction in October following a meeting that left him "confident" that a 5in iPhone is coming.

DisplaySearch analyst David Hsieh has also suggested that the bigger iPhone will arrive in the second quarter of 2014 with a screen size between 4.7 and 5.7in.
