Qualcomm QC2.0 has not been used yet, and QC3.0 fast charging technology has come

The second half of 2015 seems destined to be the first year of rapid charging technology, a variety of integrated fast charging electronic products have emerged, and fast charging mobile power supply solutions are not lagging behind, and some products are charging and discharging are using fast charging technology. As consumers, not everyone is using this kind of fast charging products, and even some people do not know, Qualcomm QC2.0 fast charging has not yet used, and QC3.0 has been officially released. Quick Charge 3.0, which claims to be 38% more efficient than its predecessor, can charge fast up to 27% faster, while helping to protect the battery's life cycle.

According to Qualcomm, Quick Charge 3.0 first adopted the Intelligent Negotiation for Optimum Voltage (INOV) algorithm, which can achieve optimal power transmission at any time and maximize efficiency.

Quick Charge 3.0 is said to be able to charge a typical mobile phone from zero to 80 percent in about 35 minutes, and traditional mobile devices without Quick Charge usually take about an hour and a half. Compared with the two generation products:

1. Compared with Quick Charge 2.0, it can increase the charging speed up to 27% or reduce the power loss up to 45%.

2, charging speed 2 times faster than Quick Charge 1.

In terms of charging voltage, Quick Charge 2.0 provides four charging voltages of 5V, 9V, 12V and 20V, while Quick Charge 3.0 provides a flexible selection of voltages from 3.6V to 20V with an increment of 200mV. This will allow the phone to get the right voltage to achieve the desired charging current, thereby minimizing power loss, improving charging efficiency and improving thermal performance.

In addition, Quick Charge 3.0 is capable of forward and backward compatibility with previous versions of Quick Charge and chargers (including USB Type-C), and has the same ultra-fast charging speed, as well as independent circuits, providing OEM vendors with more flexible options and UL certification that helps meet quality and safety standards.

The first batch of processors to support Quick Charge 3.0 technology, including Geolong 820, Geolong 620, Geolong 618, Geolong 617 and Geolong 430, are expected to be available next year. Besides, QC3.0 mobile power will soon be on the market.

Qualcomm's QC 3.0 has also brought many improvements: increased flexibility on the basis of QC 2.0, especially in terms of charging options. The QC 2.0 offers four charging voltages of 5V, 9V, 12V and 20V, while the QC 3.0 provides a flexible selection of voltages from 3.6V to 20V with an increment of 200mV. This will allow the phone to get the right voltage to achieve the desired charging current, thereby minimizing power loss, improving charging efficiency and improving thermal performance.

QC3.0 has also upgraded the authentication icon. The details are that the Arabia digital 3 is added to the upper right corner. Finally, the mobile phone with it, there is no support for this fast charging technology of the mobile phone release, and ultimately which mobile phone manufacturer grabbed the first, we will see.
