The iPhone 17 Pro felt like a brick. I had just gotten used to the featherweight feel of Apple's new iPhone Air after several days of use, but it was time to switch to the iPhone 17 Pro.

I watched Apple perform a bend test on the iPhone Air, and it was able to withstand more than 130 pounds of force with no damage.
