Are you sure? The differences between say Samsung J3 and iPhone 6 are negligible (iPhone 8 is even slightly fatter). About 1.5mm thickness and that mostly because plastics have to be thick to survive falls and not because of removable battery. If it were made partly of steel it could be a match. The size is different (J3 is bigger) and materials are a bit better in the iPhone... But we're comparing a budget phone with a flagship here. Oh, and the battery is also bigger.
