Fast charging is to increase the charging voltage and speed up the charging speed. The flash charge is to increase the charging current and speed up the charging speed. The essence of both methods is to improve the charging power, the greater the power, the shorter the charging time. In addition, the low voltage and high current of flash charging will have a higher safety factor than the high voltage and low current of fast charging, but the versatility is poor, and only official accessories can be used.
Of course, it should be noted that fast charging and flash charging are safe after reasonable optimization by the manufacturer. However, flash charging has a certain advantage in technical principle, thus improving the safety of charging.
However, flash charging also has some disadvantages. In order to achieve greater current, 2 pins are added to the charging line to achieve 7 stitches. Although the charging speed is improved, it also leads to the flash charger is not compatible with other brands of chargers, resulting in poor versatility and high hardware costs.

1. Charging speed is not the same, flash charging is faster;
< br >
2. The voltage of charging is not the same, flash charging is low voltage fast charging, fast charging is high voltage fast charging;
< br >
3. The heating degree of the mobile phone is not the same when charging, the flash charging temperature is low, and the fast charging temperature is high;
< br >
4. The security of the mobile phone is not the same when charging, and the flash charge is safer.
vivo fast charge is less damaging to the battery, and flash charge is more damaging to the battery. Just charge it up.
