Conversely, I always use Apple's iPhone case and have broken ~2 iPhone 15 Pros and four iPhone 14 Pros, so I would very much appreciate a more durable phone.
I actually used their cases for year until the iPhone 13, when the back glass cracked on day one in their case. Now I just rely on the Apple plastic case for grip and AppleCare for protection.
Similar. Been no case since the iPhone 6. I have no idea how, but I’ve only broken one screen and across our family of four (kids only starting with iPhone X, others preferring cases), we’ve broken 2 iPhone screens and one iPod screen in that time. One iPhone screen was a flex-based breakage where the screen developed a defect while the glass was intact. For all I know, plastic screens might be more subject to that failure.
Each screen replacement cost me around $75 to replace DIY.
In exchange, I have 4 3-6 year old phones that look and function as new. If you hold them just right you can see fine scratches in the light, but at a casual glance, they appear unblemished. That would not be the case if the cases were plastic. I also get the convenience of wireless charging (not possible in metal cases).
