Battery charging is divided into: fast charging, normal charging.

Mobile phone battery fast charge is mainly divided into three categories: VOOC flash charging fast charging technology, Qualcomm Quick Charge 2.0 Fast Charge Technology, MediaTek Pump Express Plus fast charging technology.

Rapid charging technology are:

VOOC flash charge

Increase the charging rate method has two direction: one is to increase the voltage, the second is to improve the current. Increasing the voltage increases during charging heat, accelerated battery aging and may pose a security risk, so the actual effect of the poor. In contrast, increasing the current is more realistic.

VOOC flash charging technology uses low-voltage, high-current mode, the charging process to ensure safety.

Qualcomm Quick Charge 2.0

Qualcomm Quick Charge 2.0 technology is Quick Charge upgraded version 1.0, using the new specification. By simultaneously increase the current and voltage charging method to improve the speed.

MediaTek Pump Express Plus

MediaTek rapid charging technology built into the PMIC Pump Express power management ICs. Allow charger charging current is determined according to the initial voltage required, issued by the PMIC pulse current command by transmitting the Vbus to the USB charger, in accordance with this directive modulation output voltage, 5V voltage is gradually increased up to the maximum charging current.
