The difference between fast charge and flash charge is:
1, the charging speed is not the same, flash charging is faster.
2, the voltage is not the same when charging, flash charging is low voltage fast charging, fast charging is high voltage fast charging.
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.
4, the security of the mobile phone is not the same when charging, flash charging is safer. Now fast charging is basically divided into two categories: 1, low voltage fast charge: represents OPPPO VOOC flash charge. 2, high voltage fast charge: are Qualcomm's universal free program, on behalf of MOTO turbo fast charge, Vivo dual engine flash charge, the basic Qualcomm chip also supports fast charge. Low voltage and high current mode: in the case of a certain voltage, increase the current, you can use the parallel circuit to shunt, under constant voltage, the smaller the pressure shared by each circuit after the parallel shunt, and the same processing in the mobile phone, the smaller the pressure endured by each circuit. High voltage constant current mode: The charging process of the general mobile phone is to first reduce the 220V voltage to 5V charger voltage, 5V charger voltage and then to 4.2V battery voltage. During the whole charging process, if the voltage is increased, heat energy is generated, so when charging, the charger will heat up, and the phone will heat up. And the greater the power consumption, the greater the damage to the battery. VOOC flash charging technology belongs to low voltage and high current fast charging, and other fast charging belongs to high voltage and low current fast charging. High voltage charging, mobile phone temperature is relatively high, relatively speaking, VOOC flash charging security is very high. Therefore, the damage to the mobile phone battery and the motherboard of the vooc flash charge is much smaller than that of the high-voltage fast charge
