Here's how Apple's new $1,000 iPhone XS compares to last year's iPhone X (AAPL)

Every fall, Apple introduces new iPhones. And every fall, many iPhone users wonder: should I upgrade?

Or, if you're looking for a new device, should you go for the cheaper option and buy last year's phone over the new iPhone XS?

This year, the differences between the two phones are minor, but there are still a few things that set the new phone apart. Here's how the iPhone X compares to the iPhone XS.
