I forecast for my next phone will be the iPhone 14 pro (or similar) I currently have a iPhone 11 pro and this is a good phone, never crashes, battery is still good. I have another year on the contact and this runs out September 2022. I think I will get the new iPhone 14 pro at that stage (as this is around the time apple release the new gadgets) on another contact. I could probably get £150 for my old phone.
