For instance, would you carry an iPhone the size of a shoebox if the rest of the space was a battery? Would you even be willing to carry one of the 80s phones that had a satchel?
I don't mind a large phone as long as it fits in my pocket. My first phone was the original Galaxy Note, which people thought was extreme at the time but now looks normal. My current phone is the Pixel Fold, which has smaller dimensions than most of my other phones but is twice as thick due to the folding aspect. Unfolded it's a small tablet bigger than any phone I've had, but folded it's actually pretty compact if you get over the thickness.
