Some people say that PD fast charger can damage the battery. For a long time after use, it will cause lower conversion rate for the lithium battery of the mobile phone. The battery will be short-life and aging faster than using ordinary chargers. Therefore, some people have a strong aversion to PD fast charger, unless their phones are in a hurry to be charged. So will PD fast charger damage the battery?

Let’s talk about the reasons why battery is aging.

1.Overcharging and over-discharging. Overcharging will accelerate the loss of lithium ions, damage the battery, and lead to the age the battery to age. While when the battery runs out, the freedom ions will be trapped, which will lose the battery capacity gradually.

2.Temperature extremes

Besides overcharging and over-discharging, temperature extremes can also affect battery life. When we play big games or run other power-hungry programs, the frequent discharge will heat that the battery temperature is too high during actual use. Likewise, when the temperature is cold, lithium ion is less active, and then the battery performance and charging performance are heavily reduced. The battery life will also be affected if still being charged compulsively.

3.The current is too high

The charging current also affects the battery life. When the battery is charging, higher current will cause serious harm to battery, even cause short circuit, explosion, combustion, etc. The charging protection circuit controls the battery charging current to be too large. Generally, the original products of manufacturers have guard circuit for charging, which controls the charging current not to be high. However, some fake chargers are not added with protection mechanism may result in serious consequences.

In general, the current fast charging technology won’t accelerate the aging of battery. While the root reason is caused by our bad charging habits.
