Qualcomm introduced Quick charge 3.0 last year and it seems that the company is ready with next version of Quick charge i.e. QC 4.0. As per the company, Quick Charge 3.0 is four times faster than conventional charging and is designed to charge twice as fast as Quick Charge 1.0 and 38 percent more efficient than Quick Charge 2.0.
Now a new rumor suggests that Qualcomm is set to announce the Quick charge 4.0 on 17th Oct in Hong-Kong. With QC 4.0, the maximum power is adjusted to 28W which is 18 W in case of QC 3.0. The QC 4.0 is designed to 5V / 4.7A ~ 5.6A and 9V / 3A, adjusted to a voltage 10mV.
We have already seen some advance charging technology from companies like Oppo which plan to come with Super VOOC charging that can charge a 2500 mAh battery to full capacity in 15 minutes. Oppo is expected to introduce this technology for the first time in their Oppo R9S smartphone scheduled to be announced on October 19.
