While the batteries that allow us
days of independence are still a mirage, Qualcomm is focusing its efforts on
charging times, reducing considerably in order to allow us to charge our
battery at least quickly. You may have already heard of Quick Charge 2.0, the
name of the technology and today we will explain in detail how it works.
Initially there was the first
version of Quick Charge, which was introduced with the Snapdragon 600, allowing
you to charge faster with a maximum current of 2A with a voltage of 5V.
With Quick Charge 2.0, present on
Snapdragon 200, 400, 410, 615, 800, 801 and 805, we will have a maximum current
of 3A with voltages which may be of 5, 9 or 12 V (but not for smartphones which
keep the 5 volts) reaching a maximum power of 36 watts (usually 15 watts for smartphones),
which should make the phase of faster recharge of at least 40% and up to a
maximum of 75%.
Obviously, to obtain these
results, you will need to attach the cable to the power supply, not to the PC,
the USB ports which still do not attain the same power that Quick Charge is
capable of delivering.
Why do we need a second adapter?
If controlled what you probably will notice that it is capable of delivering
between 1 and 2 A of current, thus not exploiting the possibility of up to 3 A
thanks to this technology. In any case, you can buy any adapter, it's Motorola
or HTC, just that supports Qualcomm Quick Charge.
