Hey guys. Im really confused and overwhelmed by the charger situation.
1. What is the difference between samsung's pd pps standard vs other brands pd standard?
2. Do all usb c to usb c cable support these charging standards?
3. Is the battery deterioration better with these new fast charging standards? My s7 edge after 3 years have only 70% battery health.
I'm wondering whether to buy new chargers and cables or use the old quick charge 2.0 chargers that i have right now with usb a to usb c cables.
I'm no expert in this but here's what I know for question number 1.
The 25W super fast charging is achieved by delivering fixed 2.77A(9V) (PD) or 2.25A(3.3-11.0V) (PPS). With PPS, the power can be varied by adjusting the voltage to achieve a specific power while for PD, both current and voltage is fixed at certain value.
So, you will not get super fast charging with any 45W PD3.0 charger without PPS as that charger cannot adjust to get that specific 25W. You will only get fast charging at 15W 3A(5V).
