I bought my wife an iPhone 11 Pro Max in 2020, and, knock on wood, outside of replacing the battery it has been going on like a champ.

I've offered to buy her a replacement phone but at this point I think she's kind of curious as to how much life she can get out of it.

I have an iPhone 13 Pro Max; I bought it in 2023 but it was a refurb so I don't actually know how old it actually is. Regardless, it's still going strong, and I am hoping it can last through whatever RAM crunch is going on.
