The listings have since vanished as Apple took the online Apple Store offline - customary before its live events - ahead of the new devices being officially unveiled in California on Wednesday evening.
Like the XS and XS MAX, the XR has a new Depth Control slider feature that lets you adjust the depth-of-field in Portrait Mode photos after they're captured, going from maximum bokeh at f/1.8 to maximum depth-of-field at f/16.
Camera-wise, the iPhone Xr packs a single-lens rear camera - the same wide-angle camera that is installed on the iPhone Xs. The iPhone XS has a 5.8-inch (14.7-cm) screen. The iPhone remains its biggest product, and the company is ready to make it even bigger. The iPhone Xs Max is the Supersized Big Mac and fries phone for an era of healthier digital diets.
It basically stuck with the same design from 2014's iPhone 6 models to last year's iPhone 8. In reality, the LCD display on iPhone XR is really good.
The XS Max features the largest screen and battery that Apple has ever used for an iPhone, a landmark reflected by a £1,099 starting price, which rises to £1,449 for the 512GB storage version. The XS will start from $999 in the USA and €1,149 ($1,226) in Germany.
The pair have a similar design and features to the existing iPhone X - including its much-hyped Face ID unlock system - with a few key additions.
Not only did Apple discontinue last year's iPhone X, it also got rid of the older (and smaller) iPhone SE and iPhone 6s, two of Apple's cheapest devices, and the last ones supporting the upcoming iOS 12 software update.
The new piece of kit is 50 percent more energy-efficient and faster than the previous processor, with apps loading 30 percent faster, too. But that's $250 less than the starting price for the XS, and XR comes with a bigger screen. It's available in six colours - white, black, blue, yellow, coral, and red - and its edges are made of aluminium rather than the iPhone XS' "surgical grade steel".
What can you do with all that handsome iPhone Xs Max screen? This is actually a pretty great improvement as the new screen feels a lot more pronounced.
"Health care products on ubitquitous [sic] devices, like smart watches, may help users seek treatment earlier and will truly empower them with more information about their health", Gottlieb and Shuren said. As far as the processor is concerned, the iPhone XR is powered by the same A12 Bionic chipset.
And, Schiller said, the XS line-up features 'the most lovely iPhone we've ever made'.
