I'm in the same boat!
I was thinking of holding off and getting the iPhone 16 Pro, but bit the bullet and will be trading in my 2018 iPhone Xs Max for the iPhone 15 Pro. I believe Apple raised their trade-in value, and with that news I figured I might as well finally just upgrade. I really want a camera quality upgrade. I also will be trading in my Apple Watch S6 for the S9, and getting the Black Friday deal.
I haven't gotten my iPhone 15 Pro in the mail yet, but I think almost 5 generations apart, you'll notice a difference no matter what. I opted for the smaller size this time around after almost a decade of using the larger sized phones I'm just ready for a change and something a bit more discreet and portable.
I think for me, one of the biggest reasons for the upgrade is the camera quality as well as the ability to record videos with Apple Log footage. I'll be using the iPhone 15 Pro to photograph a full frame camera that I want to sell, and use the money to buy the Sony A7CII. I just didn't want to buy a new full frame camera before offloading the older one.
Long story short, I found a way to justify the purchase lol
Edit: I'm also aware of the overheating and more fragile glass setup; but I always put my phone in a case, and so I opted for a really good case on Amazon's early Black Friday sale
