Portrait mode, an extra front-facing camera, an improved display resolution made people fall in love with this phone instantly. However, as Apple removed the phone's home button, they did get some occasional dirty looks.
A little pricey, but proving itself to be worth the price, this phone had it all. There were several iterations of this basic model. The iPhone XS and XS Max were released on September 21, 2018. These had a Super Retina HD display, awesome looks, and an awesome camera. However, Apple did take the 7 ate 9 jokes quite literally, as there was no iPhone 9, ever. Regardless, the A12 Bionic chip increased these phones' efficiency and battery life.
The iPhone XR was another version of this model. Released only a month later, October 26, 2018, it was announced with the iPhone X. This phone was smaller than the XS and XS Max but was bigger than the 7 and 8 plus. It wasn't as ground-breaking or as special as the X or the XS, but a colored, more affordable option, which did succeed, but everyone agreed it wasn't as good as the X, XS, or the XS Max.
