There are different ways for smartphone makers to differentiate their flagship models. But size shouldn't be a prerequisite for other features, as it is so often.
Case in point, the newly announced Google Pixel 7 series, which just started shipping to the first customers this week. When you examine the Pixel 7 and Pixel 7 Pro series side-by-side, there are several notable differences between the two: the Pro has a larger (and curved) display, a larger battery, more RAM, and a telephoto lens, and it supports one major feature, Macro Focus, that isn’t available on the lower-end Pixel. Those differences are the justification for the $300 difference between the two smartphones: the Pixel 7 starts at $599 and the Pixel 7 Pro starts at $899.
