QC3.0 Technical analysis - fasttest charging tech for your smartphones

"In fact, QC2.0 has basically solved the problem of charging power, if you increase the charging power may lead to serious problems of mobile phone, so the starting point of QC3.0 is to solve the mobile side of the receiving efficiency." Zhong Jianpeng introduced.

According to reports, Qualcomm QC3.0 compared to QC2.0 has increased the " Intelligent Negotiation for Optimum Voltage" (Intelligent Negotiation for Optimum Voltage, INOV) algorithm, you can 200mV for a step for intelligent adjustment, from 5V to 20V Voltage of the flexible choice (the original QC2.0 only supports 9V, 12V, 20V three stalls). This phone can be in different charging stage, get the right voltage, to achieve the expected charge current, making the power loss is minimized. In other words, QC3.0 can achieve the best transmission power at any time, to maximize the charging efficiency and improve the heat situation.

Qualcomm official claims, QC3.0 charge efficiency than QC1.0 increased 1 times, compared with QC2.0 increased by 38%, 4 times the ordinary charging technology, in about 35 minutes will be a typical mobile phone from zero Charge to 80%!

We can easily find QC3.0 and QC2.0 in the charge on the gap is mainly reflected in the first 45 minutes. In the 45th minute, the power gap between the two is the largest, reaching 13%. QC3.0 than QC2.0 charging speed of 18.57% faster.
In addition, QC3.0 and the previous version of the same, also supports parallel charging program, the two lines parallel charging, can improve efficiency while reducing heat.
The same to a 2750mAh battery capacity of the smart phone charge to 50%, QC3.0 parallel charging program only 19 minutes, compared to single-way charging speed close to 20%.

In addition, the power consumption, Qualcomm data also shows that QC3.0 power consumption is smaller than the previous QC2.0. And the reduction in power consumption, naturally will make the charging heat reduce.
