Fast charging technology is a really helpful feature for the heavy mobile user. Qualcomm announced its new Quick Charge 3.0 technology, promising a number of improvements over its previous generation speedy charging circuitry.

What is Quick Charge?
your smartphone charges up faster than it would without Quick Charge technology.
However, both the phone and the charger must be compatible with the same charging voltages and currents. Your phone may support charging at 9V/2A, but if you only have a 1A charger then the process will take longer. Likewise, plugging a 2A charger into a phone that can only accept 0.7A won’t make it charge any faster.

It is also possible to charge a compatible device quickly just by using a similarly high current charger, but non-certified products obviously aren’t guaranteed to work efficiency.
Qualcomm boasts that it can charge some devices up to 80 percent in just 35 minutes, but it’s very rare for the company to talk about total charge time, because it is simply less impressive. Power transfer in the latter stages of battery charging is much lower regardless of the charging tech used, hence why Quick Charge can boost your battery to 50 percent or more rather quickly, but will still take over an hour to fully charge your smartphone.

Quick Charge 3.0

Qualcomm boasts a fourfold increase in charging times over conventional chargers with Quick Charge 3.0, up from the 40 percent speed increase offered by its first generation technology. However, one of the interesting things to note is that Qualcomm isn’t touting massive increases in charging times over version 2.0, instead the company is focusing on improved efficiency this time around.

Version 2.0 supported four modes at varying power levels, 5 volts/2amps, 9V/2A, 12V/1.67A, and a 20 volt option. Quick Charge 3.0’s INOV communicates with the device to request any voltage between 3.2V and 20V at 200mV increments, allowing for a wider selection of voltages.
