I switched from 11 to the 13 mini. It feels way easier to hold and type with one hand. I use a phone case so I don’t have the problem with having the blocky side. However, the smaller screen also makes content viewing and gaming experience not as enjoyable as its larger brother.
I also enjoy taking pictures with my phone. While having a brighter screen makes it easier to see my viewfinder much easier, its smaller size also make me more difficult to see what I’m capturing.
The more efficient A15 but smaller battery lead to similar battery life between the two, which is not very satisfactory to be honest, for user like me who uses the phone frequently for content consumption.
