I can already predict I'm going to be annoyed when the iPhone 15 Pro and iPhone 15 Pro Max inevitably arrive on stage at the Apple September event. Because if the rumored periscope telephoto camera is only on the Pro Max model as claimed, it'll be another product that's fallen victim to Apple's inconsistency.
As a general rule, when Apple makes a Max or Plus variant of something, the only difference is body size, which affects the display and battery, and a slightly higher price. All other functionality should in theory be identical. Except when it isn't.
