I’m in the same boat. Right now, my pre-approval for the upgrade is a iPhone 16 Pro. I’ve always had the bigger phone ever since they were available (iPhone 6 Plus I think?). I do like the size at times, but there are other times where I think it’s awkward to use with one hand. I do love the battery life though.
My wife has always had the smaller versions, and whenever I hold her phone I think “oh this is so nice one handed”. I always went for the bigger phone as for the most part, they’ve had features not available on the smaller counterpart. Now that they’re the same, and the difference between 15 and 16 isn’t that much, I figured I might give the smaller phone a try for a year. Who knows, maybe next year the Max will have a feature or two that’s not available on the regular Pro, then I’m gonna have to go with the Max again. I feel like this is the year to try out the regular Pro for me.
