With a bigger iPhone(s appl) this year looking increasingly likely, the question then becomes what kind of resolution is that outsized screen going to pack? According to a new report from 9to5Mac, the answer is 1704 x 960.
That resolution, which is exactly 50 percent larger than the current 1136 x 640 display on the iPhone 5S, will require changes by both Apple and its developers, although it won’t be an excessively terrible transition. My colleague Kevin Tofel pointed to this exact resolution as a logical choice for Apple back in January.
Because of the way Apple handles Retina displays through pixel doubling, most developers work with a 568 x 320 effective resolution. 1704 x 960 is exactly three times as large as that base resolution. This would mean that current iPhones will run at 2x resolution, as is currently the case, and the newer unannounced iPhones would run in a “pixel-tripling” mode.
It appears like Apple has made the decision to stick with the 16 x 9 aspect ratio on the iPhone, which it adopted with the iPhone 5. Previously, our best guess for the newer iPhone resolution would have been 1440 x 960, which would have been exactly 150 percent of the 960 x 640 displays on the iPhone 4.
Most importantly, at any screen size between 4.7 and 6.5-inches, this resolution will qualify as Retina, according to Apple’s definition, which is 300 pixels per inch.
While this reported resolution remains a rumor, it makes a whole lot of sense, and we’ll most likely learn more at WWDC in June, where we’ll be on-hand.
