Fast charging of mobile phones can cause certain damage to the battery, but it is not absolute. Fast charging technology typically increases charging current and voltage to shorten charging time. This can make the battery fully charged in a shorter time.
However, high current and voltage may cause the battery to heat up or even overheat, which has a negative impact on the battery life. In addition, changes in voltage and current during the fast charging process can also have a certain negative impact on the chemical reactions inside the battery.
Therefore, it should be noted that fast charging should not be excessively used. It is recommended to use original chargers as much as possible, as they have undergone strict testing and certification to ensure compatibility with mobile phones and reduce fluctuations in battery and voltage. In addition, overcharging and excessive discharge should also be avoided, which can have a negative impact on battery life.
