The iPhone 16 series will arrive in 2024, but it's already been in the news for a long time now. All the models of the iPhone 16 lineup will feature the Action button and an extra capacitive button with a distinctive functionality. The iPhone 16 Pro Max is tipped to rock a super periscope camera while the iPhone 16 Pro model may house a tetraprism lens. Also, Apple is planning to over overheating issues with the adoption of a graphene thermal system and a metal shell over the battery.
