Increase the voltage, power is up, but efficiency has declined. With each increase in voltage, the efficiency decreased by about 10%, most of this energy into heat, so the 20V voltage files almost no one used, only to retain the 5V, 9V 12V three files. even so, hot or not, Qualicomm also feel 5V to 9V too great strides, is not practical, so can the unit being 0.2V continuously adjust voltage until you find the most appropriate? How much is the most appropriate? Qualcomm has its own unique voltage intelligent negotiation algorithm.
