That's good to know, and wow! Awesome usage. I think my last phone lasted 3 years. I ended up having to upgrade due to the charge port no longer working.
I have young kids, they end up smashing my screens :( they need a perspex version for youngins 🤣
I'm fortunate, I guess, to be a little farther down the road, so phones like the ones we have now weren't available when my kids were growing up. I do get to live it vicariously through my sons and their children, though. I don't know what you all do to keep a) kids from being on the screens all the time, but hopefully you're finding a way because b) screens don't need to be smashed very often. They're awfully expensive to replace. :)
I'm pretty happy that we got that much out of them. I think they could have gone on for a while, but at some point, and I think it's next year, Apple stops supporting them with their latest updates. So, it was pretty much time.
