what is the main difference between iphone xr and xs?
The biggest difference between the XR and XS is the display. The iPhone XR comes with a 6.1-inch Liquid Retina LCD panel, while the XS uses Super Retina OLED tech. It's also available in two sizes: 5.8-inch and 6.5-inch. It's clear, if you've got the two phones side-by-side the OLED panel looks noticeably better.
