A larger display (but not too big)
Apple made the bold move of increasing the size of the iPhone 5 with a larger 4-inch display, an improvement from its predecessor, the smaller iPhone 4s. But additional reporting and rumors suggest Apple could be coming out with an even larger display — as much as 4.7-inches or 5.5-inches diagonally — pushing the already super-sharp display to 401 pixels per inch. That would be one of the highest resolutions on any smartphone ever produced.
A stronger, sapphire crystal-based glass
Later iterations of the iPhone came with a glass front and back panel. The iPhone 5 and iPhone 5s onwards landed with a metal backing — the iPhone 5c came with a plastic shell. But the fragility of the glass display, although still stronger than regular glass, would still shatter if dropped from a height. Reports point to a sapphire-based screen that would be one of the strongest materials used on a phone's display to date. It's further proof that while accidents happen, Apple knows it.
