Can I use my old iPhone accessories?

Question

I'm considering changing my old iPhone 4S to 6, will my old accesories work with with the new model?

Answer 1

As you can imagine, Apple is determine to get as much profit from accessories and some of them won`t be compatible

Since iPhone 6 is bigger than the other iPhones, the old case you have used is a matter of history, maybe the Lightning Adapter will work or the headphones

Answer 2

iPhone owns all new and modren accesories with all new features.Data cable and charger is different than old ones similarly headphones are also different.You have to purchase a new case for it as its bigger in size than 4s.
