Earlier quoted context omitted.
As someone that went from 5S to 2016 SE to 2020 SE which is my current phone, I've been very satisfied with the 2020 SE. With each phone I have always taken steps to reduce battery usage, disabled background refresh, and manually turn on low power mode after charging every single time.
Is your hand large enough to handle the phone one-handed and touch anywhere on the screen with ease without risking a drop? If not, do you use some kind of magnet finger-ring case or similar case?
I cannot reach the upper left corner one-handed. Have not tried finger-rings or popsockets yet.
