It is wrong to focus on just the notch size with iPhone 13. This standard 13 model has a 6.1" Super Retina XDR OLED screen with Dolby Vision, now with higher brightness, the most powerful mobile chip to date - the Apple A15 Bionic, and three nicely capable 12MP cameras - two at the back and one at the front. Apple has used a new, larger sensor for the main camera and has the sensor-shift stabilization from last year's 12 Pro Max has trickled down across the entire iPhone 13 lineup.
