Qualcomm’s Quick Charge 5 Announced: 100W+ Speed To Charge Up Batteries From 0 to 50% In 5 Minutes

Qualcomm has introduced the Quick Charge 5 in a bid to reclaim its fast charging king glory. The QC5 supports speeds of 100 Watts and more while helping to keep the battery 10°C cooler and it’s 70% more efficient to boot.


Qualcomm’s tests reveals that a 4,500 mAh battery can get a 50% boost from 0% in just 5 minutes. That type of battery will reach a full charge in just 15 minutes. This occurs in the case of a dual charging solution, which splits the battery into two 2,250 mAh cells connected in series in order to increase their voltage. Triple charge is also supported.


For the support of output voltages between 3.3 and 20 Volts at minimum, with 3.3 or 5 Amps of current or (for the beefier units) 5+ Amps, QC5 power bricks are needed.

The Quick Charge 5 is built on top of USB Power Delivery PPS, but is extended with backwards compatibility with QC2 and later. It can also work with standard USB PD devices as well as Apple gadgets (iPhone 7 and newer).

Qualcomm boasts that its system is safer than plain Power Delivery. It features 8 levels of voltage protection, 3 levels of current protection, 3 levels of thermal protection and 3 timer protections, plus overvoltage protection at 25 V.


Also, the charge controller chips inside the phone won’t blindly trust the charger when it announces its capabilities using the PD protocol. It will measure its characteristics to determine the actual maximum current it can supply while keeping an eye on thermals.

Qualcomm is expectantly set to see Quick Charge 5 in smartphones coming in the third quarter of this year. Two charge controller chips that manufacturers can use were unveiled including: – SMB1396 and MSB1398. They come with the ability to support both wired and wireless input and can be used with 1 cell and 2 cell batteries, depending on the maker’s designs for the phone (1 cell designs will be limited to 45 W charging, which is still pretty quick).

Snapdragon 865 and 865+ already support QC5, though that is not an assurance that current phones will be able to use it (as the chipset needs to be paired with the new SMB chips).
