iPhone 5S or iPhone 6, whatever the nomenclature is, will have around 1.5 million pixels but will have the same screen size as iPhone 5, if the rumors are to be believed. The iPhone 5 has around 730,000 pixels. The bezel is also rumored to be narrower.
The narrow bezel was found in iPad Mini as well, so it won’t be a surprise to find it on new iPhone as well. The production for the new iPhone is expected to be in the month of June, with unveil this September, according to the sources.
