According to a report by TomsGuide, the standard models of the iPhone 15 series are expected to maintain the same 20W fast charging capability as their predecessors. However, rumours suggest that the iPhone 15 Pro variants might offer an enhanced charging capacity of up to 27W, indicating potentially faster charging rates compared to the standard models. Faster charging will allow users to rapidly charge their iPhone batteries, which is particularly useful when they need to quickly reach a minimum battery level before heading out for important tasks. Another report from MacRumors suggests that the iPhone 15 may support 15W wireless charging with third-party Qi2 chargers, expanding compatibility for faster wireless charging.
