Wait for New Screen Sizes
It looks like we could see some new screen sizes in 2020.
According to hit-or-miss publication Digitimes, Apple is working on three new 2020 iPhones that are smaller, and larger, than the current models.
The site claims Apple will launch three OLED iPhones next year with screen sizes measuring 5.42-inches, 6.06 inches and 6.67 inches.
Analyst Ming-Chi Kuo believes Apple will launch two high-end models with screens measuring 5.4-inch and 6.7-inch models (both with OLED displays) and a lower end 6.1-inch model with an OLED display.
The 2018 iPhones feature 5.8-inch (iPhone XS), 6.5-inch (iPhone XS Max), and a 6.1-inch (iPhone XR) displays. The 2019 iPhones are rumored to have the same screen sizes.
JP Morgan analyst Samik Chatterjee believes Apple will launch four new iPhones in 2020. He expects three top-of-the-line iPhone models and a budget model that borrows from the iPhone 8 series.
A report from Chinese-language Economic Daily News states that Apple will indeed release a new version of the 4.7-inch iPhone 8 in the early part of 2020.
The device will reportedly feature a 4.7-inch LCD display, A13 processor, single-lens rear camera, and 128GB of storage.
So if the current sizes aren't big enough or you're interested in a smaller iPhone, think about waiting for the 2020 iPhones.
