I'd much rather have a smaller thicker phone than a larger thinner one. The fetish for making electronic devices ever thinner is another one that passes me by. In my book 'thinner = more fragile"
And, when it comes to 'pocketability' I find pockets generally trend to expand depth-wise to accommodate thicker items. I've yet to find a garment with pockets that expand length- or width-wise to accommodate larger items
