Information found inside Apple’s latest Xcode 6 Software Development Kit (SDK) suggests Apple could introduce a higher resolution screen when the iPhone 6 launches. Previous reports claimed Apple was testing a resolution of 1704×960, but the newest files indicate the Cupertino company could move on to a 1472×828 resolution, effectively allowing Apple to include more icons on the 4.7-inch and 5.5-inch devices we believe are coming in September.
9to5Mac has an extensive report explaining the possible screen resolutions. The details were discovered inside of an iOS 8 “Springboard” application, which is another way to describe the iPhone home screen. Apparently the file is optimized for an iPhone with a resolution of 414 (width) by 736 (height).
The iPhone SDK parses hardware resolutions via “point values,” so the actual “Retina” resolution is in fact double (or potentially triple) whatever numbers the SDK presents.
That’s where the 1472×828 resolution comes into play. Through some calculations, 9to5Mac was able to discern the possible display density of both the 4.7-inch and 5.5-inch iPhones at 2x the value. If true, we could potentially see the 4.7-inch iPhone 6 screen have a 359 PPI, while the 5.5-inch iteration will slot in just above 300 PPI, still meeting the requirements for Steve Jobs’ Retina threshold.
If things were bumped up even more and rendered at 3x resolutions, the 4.7-inch iPhone 6 could sport a 539 PPI display, while the 5.5-inch could be at 460 PPI. For context, the Quad HD display found on the LG G3 is 538 PPI, while the beautiful5.1-inch Full HD display on the Galaxy S5 is 432 PPI. It’s unlikely Apple would make such a significant jump in resolution, though it’s certainly possible.
Apple’s iPhone 6 production is reportedly already in full swing, which means the company has already decided on a resolution. At the moment, it seems there are two distinct possibility though, as 9to5Mac notes, the 1472×828 resolution sounds much more likely.
We’ve seen plenty of iPhone 6 parts over the past several months, but have still yet to see a final working version. Apple supposedly has an event scheduled for Sept. 9, however, so it’s only a matter of weeks before we know once and for all.
