The USB-C Standardized Future: PD 3.1 and AVS Explained
The iPhone 17 utilizes PD 3.1 (Power Delivery) and a specialized protocol called AVS (Adjustable Voltage Supply) to manage high-speed energy transfer safely. AVS is a smart communication layer that allows the iPhone to request precise voltage adjustments in 100mV steps from the charger, rather than jumping between rigid, fixed power levels.
This handshake between the phone and the brick ensures faster, cooler top-ups because it reduces the amount of voltage conversion the phone has to do internally. Less internal conversion means significantly less heat generation, which is the primary enemy of lithium-ion batteries. By adopting the open USB PD 3.2 standard, Apple has ensured that high-quality third-party chargers can perform just as well as official accessories.
