My DD is going into KS4 next year and i promised her a new iphone. She has been using iPhone SE 2022 but I would like to buy the iPhone 13 for her however by then they will have released the iPhone 16. I want her to use it to at least she ends school so i don't want it to be discontinued very soon but the new 14 and 15 are expensive. PS: I'm buying outright from BackMarket to reduce carbon footprint plus she doesn't need a brand new phone. Any model tips? She doesn't want an old model too as she has been lately embarrased of her current phine. Any tops?
