Faster Charging
Wireless charging is currently not especially fast. Apple’s iPhones can draw up to 7.5 watts of wireless charging power from properly Qi-certified chargers, and while some competing smartphones can pull 9–10 watts, this still falls short of the high-speed charging that’s possible with an 18-watt USB-PD adapter (like the one Apple now includes with the iPhone 11 Pro).
Much of the reason for these slower charging speeds is due to issues around heat generation and the impact it has on battery life, and Apple’s choice to stay at 7.5 watts is likely conservative for this reason. However, since Apple would be designing a charger primarily for its own devices, some of its intelligent charging enhancements could also allow for safer high-speed charging.
