Rumors about Apple’s next iPhone have run the gamut from the incredibly vague to the highly specific. The latest to come to our attention is definitely one of the latter, and while it makes for an interesting rumor, it’s just a little bit odd: supposedly, the iPhone 5S could have a display with twice the pixels of the iPhone 5.
Why is that so odd? Well, we’re not talking about doubling the horizontal and vertical pixel counts (like the 3GS-to-4 transition), which would instead lead to a four-fold increase in the total pixel number. Instead, if we’re talking about Apple moving from a screen with 727,000 pixels like it has now up to 1,454,000 pixels, the actual resolution would only grow from 640 x 1136 to somewhere around 906 x 1606.
When Apple moved from the 3GS to the iPhone 4, it could easily deal with the new resolution by scaling-up graphics from old apps – then it was a simple factor of two. For this proposed change, we’d be scaling everything by wacky irrational numbers – it wouldn’t be clean in the least, which makes us hesitant to believe that Apple could really be going down this route.
