The upcoming iPhone 15 series is expected to bring some significant changes for Apple. One major change is the introduction of USB-C ports for charging, replacing the Lightning ports that have been used for almost a decade. The Pro models will feature a titanium frame and an Action Button for specific actions. The standard models will have a 48 MP camera and a Dynamic Island replacing the notch. The Pro Max model may have a periscope lens for improved zoom capabilities. The Pro models are also expected to be priced higher than previous versions.
