Is the mobile phone fast charging technology really good? Is it related to the data line?

In this age of communication, what is the most used thing in one day? Presumably I don’t say that everyone knows it. It’s a mobile phone. The mobile phone can say that now. For today’s people, it’s equal to the second wife. The mobile phone is much more used and used for a long time. The problem naturally follows. The most people’s headaches are. It should be that the battery is very short of electricity, and the charging is troublesome. Usually it takes a few hours to complete. Many cell phone manufacturers will work hard on batteries and data cables. The recently introduced mobile fast charging technology - the fastest one minute full, which greatly reduces the user's charging time, this advantage is good, but in the data line manufacturers technical department for more than 10 years, I need to publish their own Personally, I personally think that the disadvantages are more prominent than the advantages. Here are some points for everyone to analyze:

1. Low-voltage, high-current mode: In the case of a certain voltage, the current can be increased, and the shunt can be shunted using a parallel circuit. Under a constant voltage, the pressure shared by each circuit after parallel shunting is smaller, which is also performed in the mobile phone. In the same way, the pressure on each circuit is smaller.

2, high voltage and high current mode: This method increases the current and voltage at the same time, so from the previous formula P = UI, we can know that this way is the best way to increase power, but increase the voltage At the same time, more heat is generated, so that more energy is consumed therein, and the voltage and current are not increased arbitrarily without restriction.

3, high voltage constant current mode: the general mobile phone charging process is to first 220V voltage down to 5V charger voltage, 5V charger voltage and then down to 4.2V battery voltage. During the entire charging process, if the voltage is increased, heat energy is generated, so when charging, the charger will generate heat and the mobile phone will also generate heat. And the greater the power consumption, the greater the damage to the battery.

The definition of fast charging technology is: In the charging process of a mobile phone, the charger is required to dynamically adjust the output voltage and current according to parameters such as battery voltage, power and temperature, so this fast charging technology is not associated with the data line.
