USB PD, especially its PPS feature, now underpins fast charging on most major phones, including Apple's iPhone 17 and Android flagships like Samsung's Galaxy S26 Ultra and Google's Pixel 11 series. Qualcomm Quick Charge, once dominant, has largely folded into USB PD compatibility, while brands like OnePlus, Oppo and Xiaomi still rely on proprietary systems such as SuperVOOC and HyperCharge for their fastest speeds.
