CELLPHONE - iPHONE- STUDENTS

THE CHEAPER iPhone, which became available two Fridays ago, is a model that most people, most students should consider buying.

I tested an XR for four days, and here are the highlights:

A BRIGHT AND VIBRANT DISPLAY :
Apple developed a new kind of  LCD to improve color accuracy and squeeze the XR's screen into the the corners of the phone.

The result is what  Apple calls a Liquid Retina display, which looks brighter and more vibrant than the past iPhone LCD screens.

I confess that I struggled to see a difference between the Liquid Retina screen and the OLED on the XS model. The distinction is most evident in blacks :

If you look at a photo taken in the dark, you will notice that the blacks on the XR screen have a little blueglow, which is coming from the blacklight used to illuminate the screen, while  the black on the XS  looks darker and more realistic because the OLED  technology turns off  individual pixels  to make them black.

While browsing Instagram on the  XR  and the  XS, I came across a few photos that clearly looked better on the XS's OLED  screen. One example was a professional photo for a New York Times Cooking article about a cherry season.

In the photo, which shows a variety of cherries in colorful baskets, the reds and cyans looked more accurate on the XS  than on the XR, and some of the red stains on the wood table were more visible on the XS.

These downsides were trivial. The vast majority of your time on a phone will probably be spent looking at amateur photos taken by friends and family, so its worth saving $250 to have this slightly less vibrant screen.
