Samsung’s new Galaxy S20 series of flagship phones are the first phones to be certified by the USB Implementers Forum as compatible with the new Certified USB Fast Charger industry standard.
Phones and chargers certified under the program must use USB-C connectors, support USB-PD (Power Delivery) 3.0, as well as the new Programmable Power Supply (PPS) feature of USB-PD 3.0. PPS allows the phone to specify the precise voltage and current required for optimal charging throughout the charge cycle, enabling faster charging speeds than are possible with USB-PD alone.
“Galaxy S20 series has been certified to be compliant to the USB standards which means Galaxy S20 has met the highest standards in the industry.” Said Kisun Lee, VP of Power Solution at Samsung. “We believe that a convenient user experience is the most important value and using a robust and inherently safe USB PD standard ensures interoperability and an optimized charging experience.”\
“The Samsung Galaxy S20 series certification announcement is yet another testament to the wide-ranging benefits that the USB-IF Certified USB Charging Initiative provides to the mobile industry, which includes reliable USB Fast Charging capabilities,” said Jeff Ravencraft, USB-IF President and COO. “USB-IF compliance means that products were certified to be compliant to the appropriate USB specifications and have been tested for interoperability with other USB products.”
Certified USB Fast Chargers are backwards compatible with older USB-C and USB-PD devices. Many current USB-C phones implement fast charging using older USB-PD standards, various versions of Qualcomm’s Quick Charge technology, or proprietary technology specific to that manufacturer. The USB Implementers Forum hopes to standardize wired fast charging with this new certification program.
