First of all, we have to learn about how fast is the real sense of fast charging. According to the statement on spec page for Apple’s latest phones, there is a single line saying fast charging can add up to a 50 percent charge in 30 minutes.

When you use adapters not fast enough or even fast wireless charging pad, you won’t hear the second DING. The second DING comes a second after the first.
