There is a lot of talk and anticipation for the next Apple Inc. (NASDAQ:AAPL) iPhone. Whether it will be the iPhone 5S or iPhone 6 remains to be seen, for now we can only speculate what to expect with rumors and remembering the past.

iPhone 5s or iPhone 6?

It’s still highly speculated that Apple will release the iPhone 5S later on this year and save the iPhone 6 for next year. Given Apple’s history, the iPhone 5S will most likely be a small upgrade whereas iPhone 6 should feature better upgrades. There are numerous reports regarding both phones and nothing has been confirmed yet by Apple Inc. (NASDAQ:AAPL), but we can make educated guesses for what to expect.

iPhone 5s may look like iPhone 5

It’s estimated that the iPhone 6 will have a large display size and more improved design. Since Apple’s chief executive officer Tim Cook has knocked the current big screens with high-resolution displays, it’s highly unlikely this screen will feature a huge display. It is predicted the iPhone 5S  will look a lot like the iPhone 5 with a four-inch display. We might also see a new display, most particularly Sharp IGZO. This could give the phone a better design and improved battery life.

Gotta Be Mobile added, “Even though Tim Cook is currently slamming bigger displays on smartphones, we could see Apple Inc. (NASDAQ:AAPL) introduce one on the iPhone 6 in 2014 alongside claims it is the best display since Retina. An iPhone 6 prototype reportedly came with a 4.8-inch display with a higher than Retina Display resolution. Couple this with advances in high-resolution large screen displays like the new bright LG 5.2-inch super thin 1080P display and there is an opening for a new screen size.”

iPhone 5s may feature four inch Retina Display

Although there are no iPhone 6 design leaks, there are concept ideas which include a wraparound design and waterproof design. As for possible features, it’s likely the iPhone 5S will feature a four inch Retina display, Apple Inc. (NASDAQ:AAPL) A7 processor, 2GB RAM, 12-13 MP rear camera, fingerprint reader, and iOS 7.  The iPhone 6 is likely to feature Apple A8 processor, a larger screen, fingerprint reader, and iOS 8.
