Wait for Better Displays
According to a noted leaker, the 2020 iPhones might come with faster 120Hz 'ProMotion' displays.
The information comes from Ice Universe who is well-known for leaking accurate information about Android phones ahead of launch.
He claims that Apple is, as of right now, considering a switchable 60Hz/120Hz refresh rate screen on the iPhone in 2020" and that it's currently in discussions with Samsung and LG.
The faster refresh rate would lead to a smoother experience (more fluid scrolling, better responsiveness, faster motion) on the display.
His report has been backed up by hit-or-miss publication Digitimes. According to Digitimes, the 2020 iPhones will come with 120Hz screens. If that's something that interests you, think about waiting.
The iPhone 11 Pro and iPhone 11 Pro Max both come with beautiful OLED displays (they're two of the best screens ever made) while the cheaper, more colorful iPhone 11 comes with an LCD display. This could change in 2020.
According to The Wall Street Journal, Apple is planning to ditch the LCD display in 2020 and use OLED panels across the board.
This isn't the first time we've heard this rumor so it's trending in the right direction. A more recent report from Digitimes backs this up. So does a report from Kuo.
The iPhone 11's LCD display is good enough for many people, but the OLED display is the clear winner between the two.
