They do last longer than a couple of years, and _are_ supported too: I have an iPhone 6s around the house that I use to play music over Bluetooth, and it just got the iOS 15 update. iPhone 6s was released in 2015. The only problem with it is the battery. It could use a replacement, but since I don't use it as the main device, I don't much care. Otherwise, it works perfectly fine.
