I have an iPhone 6s, I’m thinking of upgrading to the iPhone XS or iPhone 11 Pro (equiv. of X/XS). A recommendation is that you do not upgrade your iPhone every year, since you will waste money on practically the same phone. That is why Apple didn’t sell the XS WITH the X, otherwise the X would outsell the XS since the XS is the same thing but better. I will update to the 11 Pro in 2020. I will still get the the iPhone 12 (2020 iPhone) in 2021 since it has the iPhone SE style. Afterward I will wait until the next iPhone has a big change in it that everyone will want to buy. (EG, no one is really buying the 11 series since the 2020 iPhone will be the best iPhone on sale since the 6).
