The topic mentioned the charger choice 5w or 20w, in fact, is entangled in the fast charge is not an impact on battery life.

For Apple, since the iPhone 8 began to support wired PD fast charging and wireless charging, Apple has also brought the iPhone into the market of fast charging and wireless charging. iPhone 12 release, Apple in accordance with the practice in the introduction of the official website did not say that the iPhone support PD fast charge, only said that half an hour can charge 50%, need to use 20W or more power charger. But Apple is not equipped with a high-power charger, can only choose separately. This also shows that Apple's PD protocol supports fast charging.

Fast charging does not affect battery life
Relatively speaking, 20w hurts the battery. 5W is more protective of the battery, because the charging speed is relatively slow, you can better protect the battery. With Apple's original 20W charger as an example, the power can reach 20W, but if it is 5W, it is only 5W during operation, so relatively speaking, 5W can protect the battery.

In the process of use, the battery will also be lost, such as the mobile phone needs electricity when the screen is lit, it will always be in the stage of loss, the battery itself is a kind of loss, and if there is no special detection, the mobile phone is estimated to be able to use about 1 to 2 years.
Apple's 5 - and 20-watt chargers don't actually hurt the battery,
Our change is that we must pay attention to the mobile phone when charging, do not play with the mobile phone while charging, which will affect the battery life and the normal mobile phone charging.
If an abnormal situation occurs in the charging type, it is to the point, because it is particularly stuffy and heart. It worked, right?
At present, only Apple 8 and above models support 18w fast charge, and the pd protocol must be used. Not any charging head 20w to charge the Apple phone can reach 18w. Therefore, the Apple fast charge and 5w fast charge have the same battery loss.
