The top charging speeds range from 18W to 68W. Motorola: The company’s TurboPower fast charging technology uses both Qualcomm QuickCharge 3.0 and USB PD, depending on the phone.Google: Pixel phones use USB PD with PPS, with fast charging speeds ranging from 18W to 30W.Most Samsung phones have 25W fast charging support, but some flagships also support 45W charging. Samsung: The company uses Samsung Super Fast Charging and Samsung Super Fast Charging 2.0 technologies, which are based on USB Power Delivery (USB PD) and Programmable Power Supply (PPS).To ensure rapid, energy-efficient charging, check to see if your phone supports one of the modern power standards, then purchase an accessory with the protocol built-in.īelow, we'll explore the fast-charging protocols commonly employed by smartphone manufacturers and the corresponding charging speeds you can anticipate. While practically any charger can juice up your phone, guaranteeing fast charging, especially with a conventional power brick, is uncertain. Which fast charging protocol does your phone use? Not surprisingly, this likely explains why manufacturers like Google and Samsung incorporate PPS technology into their smartphones and tablets. Consequently, reduced power conversion loss and heat dissipation contribute to long-term battery health. PPS was introduced as a supplemental specification to the USB PD 3.0 standard to fix this issue PPS allows devices to request a specific voltage and current to optimize battery charging time. As a result, the voltage difference between what was sent from the charger and what was used by the battery would be lost in the form of unnecessary heat. The device battery would then have to adjust the voltage and current as necessary. Early versions of USB PD lacked support for step-wise voltage variation, causing chargers to provide higher voltage levels than needed by the devices. ![]() That said, EPR chargers and cables are still a few years away from widespread availability.Ĭonventional power bricks and tiny chargers already breathe life into millions of smartphones, tablets, speakers, earbuds, gaming consoles, and laptops. USB PD is excellent, and its latest Extended Power Range (EPR) specification supports up to 240W of power to mobile devices through the USB standard. It comes from the folks responsible for maintaining the USB standard: USB Implementers Forum or USB-IF. USB Power Delivery (USB PD) is one of the fast-charging standards that has gained much recognition over the last few years. If their batteries can't last for days on end, at least we can make them charge rapidly that’s the mantra championed by smartphone designers. ![]() As battery technology lags behind those lightning-fast leaps in smartphone development cycles, manufacturers are forced to innovate. ![]() Inevitably, as with all technology, smartphones get more powerful with every generation.
