The current entry level iPhone; iPhone SE 2020 with A13 is now faster in Single Threaded performance than ALL current shipping Android, including Flagship Android. And judging by the Qualcomm roadmap, this will likely remain the same in 2021 as well.
This is important if you are doing or using Web Apps like Discourse which requires JS processing. The Cost of javascript is still huge. [1] [2]. And While Mobile Apps are well optimised to take advantage of multiple cores, it will still be bounded by Amdahl's law[3].
And a point on devices size.
Japan, the nation which prefer single handed usage and small size Smartphone, and has a hand size smaller than average, median or general US / EU population, has overwhelmingly voted with their pocket on the 4.7" Devices, and not the previous 4" iPhone SE. Even During the iPhone 7, iPhone 8 era.
So I do suggest before people writing off 4.7" as being large, please try and give it a go first.
Another Point worth pointing out, once the tech for FaceID Shrinks to small enough or could be done under display, a 4.7" Edge to Edge Face ID Design would be exactly the same size as the previous iPhone SE. I believe this could be the long term goal for Apple.
