Quick Charge 2.0 Technology

In addition, Qualcomm's Quick Charge 2.0 technology, its core technology is to reduce the charging current by increasing the charging voltage, thereby reducing the power consumption on the charging line, there will be a corresponding step-down circuit on the mobile phone side, the circuit will be high voltage low The flow is converted to a low pressure and high flow. Therefore, in essence, flash charging and Quick Charge 2.0 are the same, by supplying a large charging current to the mobile phone battery at the beginning of the battery, and gradually reducing the charging current as the battery voltage increases.

Advantages and disadvantages, Quick Charge 2.0's biggest advantage is its technical compatibility and inheritance is better, its external interface uses the universal USB standard, no need to buy a dedicated cable, but the phone without fast charging function is using Quick Charge When the 2.0 charger is charged, it is charged in the usual way.

Its disadvantage is that the side of the mobile phone has a relatively large heat relative to the flash-filled mobile phone, and the charging speed is slightly slower. From a technical point of view, flash charging is actually better than Quick Charge 2.0, because it has adjusted the various aspects of charging, but to be popular, simply looking at the technology itself is unrealistic.

From the development point of view, because of the nature of the integrated chip, Quick Charge 2.0 is more suitable for popularization, and many high-end models have already adopted this technology, which has basically formed an ecological environment, and the driving force of the giant will arise. To a big role.
