Not exactly what you're asking but I went from a big Android phone to an iPhone (regular one, not mini or max). Also, I got the non-pro version so it weighs less, and I don't use a case - again for the size/weight.

It's awesome. To get the most important thing out of the way - I don't notice the smaller screen at all. And it's not even "I got used to it and now I don't notice it," there was never a need to get used to it.

Otherwise, few other upsides to using the smaller phone:

• It fits in every pocket, not just in my big pockets
• It's smaller, so my fingers don't tire from being 'stretched'
• It's much lighter so my wrist doesn't care how long I hold it

I definitely recommend upgrading to a more portable phone. It's worth it.
