Mine is 4 years old and still works perfectly fine. I did start looking at some phones with a better camera recently, because my wife got a new one not so long ago and the difference in picture quality is almost absurd. But then I have also started looking at getting an actual camera to remedy that, for the price of a flagship phone you can get some amazing digital camera's.

Same. I guess I'm hard on my phones, because usually I start having microphones, speakers, and buttons start failing at about the 2 year mark. My last phone was still perfect at the 2 year mark, but I dropped it on carpet from 2 feet off the ground and the touchscreen didn't work anymore. I was leaving on a trip like 3 days later, so I didn't have time to get it repaired.

So I'm pretty consistent about getting a new phone every 2 years.

I usually get mid-range phones, though. Like the cheap ones from high end brands. My current phone is the entry level pixel 7, which I got for $500. I don't really mind spending $500 every other year.
