IPhone naming

iPhones are named with "iPhone" followed by a number, which denotes the iPhone generation, and sometimes a suffix (such as Plus, Pro, Pro Max). The current naming pattern is that "Plus" indicates a physically larger iPhone model of the same generation, sometimes with higher end features (iPhones 6 Plus through iPhone 16 Plus). "Max" indicates the largest model of the premium model (iPhones XS Max). "Pro" indicates the premium model (iPhones 11 Pro through iPhone 16 Pro). "Pro Max" indicates the largest model of the "Pro" line indicated as a premium model (iPhone 11 Pro Max through iPhone 16 Pro Max). "e" indicates the entry-level model (iPhone 16e). Currently, models with just a number (i.e. without a suffix) indicate the flagship of the iPhone (iPhones 11 through iPhone 16).

The suffixes S, R, C and SE were previously used. "S" was used to denote a slight upgrade (iPhone 3GS, 4S, 5S, 6S & 6S Plus, XS & XS Max), but it has since been dropped; iPhone XS and XS Max were the last models to feature the "S". "R" was used to denote the lower-priced iPhone XR, which is the only iPhone with "R" in its name. Similarly, "C" was used to denote the lower-priced iPhone 5C, a variant of the iPhone 5 with similar features and internals, and is the only iPhone with "C" in its name. The "SE" used in the entry-level iPhone SE line stands for "Special Edition".^[1][2] They were all named and marketed as simply "iPhone SE", and can be differentiated by generation suffixes. iPhone X (pronounced "10"), iPhone XR (pronounced "10R") and iPhone XS and XS Max (pronounced "10S") are currently the only iPhones to have been branded with Roman numerals (X).
