You can get a lot of used iPhone for $500. I bought my XS maybe 3 years ago for a little less than 500€. I’m still using it. The battery starts to age but not enough for a replacement (it generally finishes the day but I have no more extra buffer). Other than that, I can’t imagine what could make me buy anything else.
I would totally love an iPhone mini because i find the Xs too big but i don’t feel like it’s worth spending money. I would also totally buy a non-googled Android (because I don’t like nowadays Apple mentality) that I could keep updated for years but it just doesn’t exists.
So here I am, with my Xs, which honestly, feels like, to me, an exceptional phone for 2022: beautiful, fast, updated, nice picture quality, reliable, and totally cheap. It would be a total dream if the App Store wasn’t a dictature or if side loading was possible.
