Besides, thermal constraints would make 240W (or anything close to it) impractical and unnecessary for a handset anyway.
Key facts
- USB PD 3.1 raised the maximum supported power to 240W, while USB PD 3.2 is the spec's latest revision
- Meanwhile, Google's Pixel 11 models use USB-C PPS charging to reach their fastest advertised speeds, with the Pixel 11 Pro designed for a 45W PPS charger
- Samsung and Google flagships have similar features: Battery Protection on Samsung phones, and Charging Optimization (including Adaptive Charging and an 80 percent limit) on Pixel phones
- Samsung's Galaxy S26 Ultra uses PPS as part of its 60W "Super Fast Charging 3.0" system
Summary
"Fast charging" has become a catch-all term that can mean many different things. Years ago, USB charging was a slow trickle of power. To be clear, USB-C itself doesn't tell you much: A device with that port doesn't necessarily support fast charging. Getting the absolute most out of fast charging usually means matching the device with the right cable and charger. Today, USB Power Delivery (USB PD) is the closest they have to a universal standard.
