“September 6th is the best suggested time by which to have sold your old iPhone. Waiting could cost you as much as $104 by September 20th, which the iPhone 14 Pro Max 1TB model had lost in 2023 by the time the iPhone 15 hit stores.” SellCell
The big question is, what will you do for a phone between tomorrow and the September 20th release date of the new iPhone 16 series? Some phone buyers will let you lock in a price for up to 30 days which will allow you to sell your older iPhone, get close to the top price for it, buy your new iPhone, receive your new iPhone 16 model, and mail your old phone to the buyer.
