>A final note: all of this is about software support - none of this is actually about useful lifespan. Two years ago my phone crapped out on me and I used a friend's old iPhone SE (1st generation, 2016) for a couple months - it was trending hard towards a trash can. The battery lasts about 2 years before it needs replacement, the glass screen breaks easily and aftermarket replacements have touch input issues, and running the latest iOS on it had things moving slower than LA traffic. The screen doesn't break that easily unless you drop it face down on a sidewalk or accidentally close it in a rat trap (don't ask). Tip for buying screens if they do, get working pulls or buy from a vendor that does high quality refurbs on OEM screens. I've had good luck with the 'premium refurbished' from injuredgadgets, their batteries have held up (even if the battery health % never goes down) as well. Ifixit's aftermarket screen had poor colors and one of my batteries turned into a spicy pillow in about a month of use, so I can only recommend them for guides and tools. As for speed, I don't use them as a primary anymore but unless your battery is shot and iOS is throttling it, maps and payments don't seem to lag. Data speeds will be unimpressive, it can't aggregate carriers. Otherwise it works fine. For me it's a great utilitarian secondary device, basically the phone that always 'just works'. Absolutely usable, in fact there are use cases where it excels simply because it can be used with wired headphones while plugged into a charger at the same time and I can't think of any other supported device on the market able to do that.
