"Quick Charge 5, our fastest and most versatile charging solution, will enable consumers to enjoy their devices for longer periods of time, without worrying about the time required to recharge. We are proud to expand our technology portfolio and make accessible 100W+ charging a commercial reality," Ev Roach, VP Product Management, Qualcomm Technologies, Inc. said.
According to tests carried out by Qualcomm, a 4,500 mAh battery can be charged from 0% to 50 in just 5 mins, while 15 mins will be enough to fully charge the battery. This is same as a dual charging solution, which splits the battery into two cells connected in series to increase their voltage.
Qualcomm's Quick Charge 5 power bricks are required to support output voltages between 3.3 and 20 Volts at minimum, with 3.3 or 5 Amps of current or 5+ Amps. QC5 is built on top of USB Power Delivery PPS, though its compatible with QC2 and later. It also works with standard USB PD devices and as well as Apple devices(iPhone 7 and newer).

The company unveiled two charge controller chips which manufacturers can use, namely; SMB1396 and MSB1398. They both support wired and wireless input and can be used with 1 cell and 2 cell batteries, though 1 cell will be limited to 45 W charging, which is still pretty much quick.
Qualcomm expects phone manufacturers to start using Quick Charge 5 in smartphone in Q4 of this year, though Snapdragon 865 and 865+ both support QC5.
