The iPhone XS has a 5.8-inch screen and the XS Max features a large 6.5-inch display. Both phones will run on a new A12 Bionic chip with a neural engine. Schiller says the processor can take on "5 trillion" processes per second. The iPhone was already fast, but with iOS 12, iPhone XS and XS Max will be even faster. Apps will apparently open 30% faster.
