Bought my iPhone XR at the end of last year, and I don’t think upgrading from the XR to the iPhone 11 would actually give me any more than I already need!
Sure, if you’re heavily into iPhone photography then the 11 looks a good choice, but other than that, I’m afraid not!
I’ll probably wait to see what next year brings.
I don’t think I am in any position to upgrade or have the budget for a new phone. I just got my iPhone 6 last Christmas as a gift so I’m guessing that I’ll be stuck with what I got even though it won’t be able to get IOS 13 since mine is not a S.
