Qualcomm wants to regain the title of king of fast charging by introducing Quick Charge 5. This is a big leap with QC4, supports speeds of 100 W and above, keeping the battery at 10 ° C cooler and 70% more efficient at startup.

According to Qualcomm's tests, the 4,500mAh battery can be charged from 0% to 50% in just 5 minutes. It takes 15 minutes to fully charge this battery. This is the case with the dual-charge solution, which divides the battery into two 2250mAh cells to increase the voltage. Triple charging is also supported.

QC5 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 (for the beefier units) 5+ Amps.

Quick Charge 5 is built on top of USB Power Delivery PPS, but it extends it 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 claims its system is safer than plain Power Delivery too. It features 8 levels of voltage protection, 3 levels of current protection, 3 levels of thermal protection and 3 timer protections, plus over-voltage protection at 25 V.

Qualcomm expects to see Quick Charge 5 in smartphones coming in the third quarter of this year. While faster charging sounds great, we’re still not sure on how 100W or greater wattages will impact battery longevity.

Snapdragon 865 and 865+ already support QC5, though that doesn’t mean that current phones will be able to use it (as the chipset needs to be paired with the new SMB chips).
