Joining a growing number of analysts, if not the public sentiment at large, Chinese analyst Sun Changxu recently said that she anticipates the iPhone 6 will feature a 4.7-inch display. What's more, Changxu also anticipates that Apple will release an even larger screened device with a 5.7 inch display. That, of course, would take Apple into phablet country.
Notably, this isn't the first we've heard of Apple looking to increase the size of the iPhone in future models. Historically, Apple has been extremely slow to change the form factor of the iPhone. Indeed, it wasn't until the iPhone 5 that Apple finally increased the screen size from 3.5 inches to 4.
While larger screen sizes may have seemed gimmicky at first, brisk and impressive sales of Android devices like the Galaxy Note prove that there is a market for big, shiny displays. While perhaps not religiously tied to the notion of smaller screens, Apple CEO Tim Cook has previously stated that bigger screens often come with user tradeoffs - such as decreased battery life - that Apple isn't comfortable making.That said, if a bigger screen iPhone is in the works, you can be safe in assuming that battery life on the device won't take a huge hit.
Interestingly enough, when Tim Cook was in China last week to commemorate the iPhone/China Mobile deal, he was asked point blank if users can expect bigger iPhones in the future.
Naturally, Cook wasn't going to spill the beans, answering: "We never talk about future things. We have great things we are working on but we want to keep them secret. That way you will be so much happier when you see it."
