Smartphones have evolved and the iPhone isn’t as novel as it used to be. If Apple wants to change the game again, here are six techs it should be looking at.

What will Apple’s next iPhone be like? If rumors are to believed, it’s going to be a radical redesign from previous models, mining some of the best features from the current crop of mobile-phone technology. (For a rundown of the most prevalent—and wildest—rumors, check out our roundup here.)

But that’s almost a given. With competitors offering things like OLED screens, NFC communication for mobile payments, and 4G connectivity, Apple has to be at least considering including those things for iPhone 5 (or the iPhone 4S, or whatever it’s going to be called). But what about those wild cards, the things on the outskirts of current mobile tech, which could give the next iPhone an edge over all comers?

Apple’s pulled high-tech rabbits out of its hat before. With the iPhone 4, it introduced two unexpectedly novel features: the so-called retina display and the external antenna. While the iPhone 4’s retina screen still reigns as phone display on the market with the highest pixel density, the external antenna made headlines for all the wrong reasons, leading to “antennagate” after several users posted evidence of the phone’s “death grip.”

Questionable antenna designs aside, there’s no shortage of bleeding-edge phone technologies that could be game-changers. Some have already begun to appear in phones, while others have only been seen in prototypes or laboratories thus far. In either case, their benefits and abilities would give any phone that integrates them an boost in the rapidly evolving world of mobile.

There isn’t a phone manufacturer on the planet right now that’s making plans around NFC and 4G. But how many would introduce radically different screen or camera technologies, a new type of connector, or solar charging? We know almost certainly these features won’t be in iPhone 5, but we can still dream… of iPhone 6.
