The smart flash charge function mainly refers to the fast charging function of the mobile phone.
< br >
Battery life is a major problem in the use of mobile phones, and the way to solve the battery life problem is to use fast charging technology to quickly charge the mobile phone battery, also known as flash charging function.
< br >
If you want to achieve the flash charge function, you need the charger to meet sufficient output current and output voltage.

Categories of fast charging technologies:

1. VOOC flash charge
< br >
There are two ways to improve the charging speed: increase the voltage and increase the current. Increasing the voltage will increase the heat generated during charging, accelerate battery aging and may bring safety risks, so the actual effect is not good. By contrast, raising the current is more realistic.

VOOC flash charging technology adopts low voltage and high current mode to ensure the safety of charging process.

2. Qualcomm Quick Charge 2.0
< br >
Qualcomm's Quick Charge 2.0 technology is an upgraded version of Quick Charge 1.0 with a new specification. The charging speed is improved by increasing the current and voltage at the same time.

3. Mediatek Pump Express Plus
< br >
Mediatek's new fast-charging technology, the Pump Express, is built into PMIC's power management integrated circuit. The charger is allowed to determine the initial voltage required for charging according to the current, and the PMIC sends a pulse current command through the USB Vbus to the charger, and the charger adjusts the output voltage according to the command, and the voltage gradually increases to up to 5V to achieve the maximum charging current.
Smart flash charge refers to realme's own super flash charge technology, 4000mAh battery only 3 minutes to flash 33% of the power, this technology is called smart flash charge.
