just make normal sized cellphones again, please!
They can’t even fit in a headphone jack in the large phones. A small phone would require a SIM adapter and external battery if they ever make one.
They don’t want to fit a headphone jack. See the Asus ZenFone it’s smaller than usual yet still has a headphone jack and expandable storage
Not possible at the moment. Without the large size, you can’t fit an adequate battery to last a day or longer.
Not to mention that many people want good cameras on their phone, an they need space as well.
Display needs a lot of battery, less of it and you dont need such a big one. Than make it two millimeters thicker and the problem is solved.
That is a factor, but not a big one anymore. Not as big as the communication chips (bluetooth, wifi, 4g/5g). Also rendering apps and websites is excessively expensive, specially if you want to have HiDPI and 60Hz or more.
