Despite little verifiable information, Apple may already have a big hit on its hands with the iPhone 6. According to a new survey from 451 Research’s ChangeWave service, interest in a larger and faster iPhone is hitting an “unprecedented level,” out pacing the previous iPhone 5s and iPhone 5.

When ChangeWave asked more than 4,100 people, mostly in North America, about their interest in the iPhone 6, 40 percent of respondents said they are “very likely” or “somewhat likely” to buy an iPhone with a “larger screen size” and a “faster processor.” Current rumors suggest that the next iPhone will come in two sizes, a 4.7-inch version and a 5.5-inch version. Both will most probably possess the A8 processor, the next-in-line processor for Apple’s A-series system-on-a-chip.

"This is the highest level of demand for an unannounced Apple model in a ChangeWave survey -- stronger than we've seen in previous years for the iPhone 5s and iPhone 5 models prior to their announcements," Andy Golub of 451 Research stated. "Speculation over a larger screen iPhone is clearly striking a chord with consumers."

The iPhone 5s showed very little interest when polled in March 2013, with only 26 percent of people interested in it. While interest may have boomed since last year, the most of it has come courtesy of the “somewhat likely” category, which grew 9 percentage points year over year. The “very likely” interest segment was up 5 percentage points since 2013, but was still down 1 point since 2012.

Users of the popular social network Reddit posed the question, “How many of you actually want a bigger iPhone?” Respondents were both in favor of a larger smartphone from Apple, but stated that the iPhone 5 is still conveniently sized. Users stated that the size of a phone is just a personal preference.

“I'm 6'3" and would be fine with a bigger phone as long as it fits my pocket well and I can use it one-handed most of the time,” stated user PairOfMonocles2. “That said, the 5s works fine for me so I wouldn't ditch the iPhone if a bigger one doesn't appear.”
