Apple has released its second-generation iPhone X in the United States, but its predecessor was released earlier in 2016.
The XS model has a new design, more aggressive design language, and a much bigger battery.
The iPhone Xs Max is a slightly larger version of the X with a slightly different design language and a slightly bigger battery (1,500mAh compared to the X’s 800mAh).
Both of those changes are the result of Apple taking a step back from its flagship smartphone line.
The new iPhone X models are also slightly thicker than the iPhone X, and are now available in a variety of sizes, including 4.7-inches and 5.5-inches, the company says.
Here’s what to know about the Xs, XS, X and X Plus.
