Apple's 2018 iPhone lineup may literally be its biggest ever. According to Bloomberg in a Monday report, Apple is designing what would be its largest iPhone ever, an upgraded edition of 2017's iPhone X and a cheaper iPhone that would keep the iPhone X design while making concessions for a lower price.

Citing "people familiar with the products" who spoke anonymously, Bloomberg says Apple is running production tests with suppliers involving the three new iPhone models. Previous rumors have pointed to the possible existence of three 2018 iPhone models, but this latest report includes many details about the specs and improvements that might be on the way.
