Hi, sometimes when I connect my 11 Pro Max to the charger, it beep twice. As far as I know, this double beeps indicate fast charging if you are using 3rd party chargers. However, I am using the charger that came with the iPhone and sometimes it beeps twice, sometimes just once. Is it a bug? Is my charger defect? Or my phone?

P.S: I am on iOS 13.3.

It’s just a glitch. It’s Just like sometimes when there’s a delay with the ‘charging tone’ when you first plug in the iPhone, and then when you hit the power button, you hear the chime. It’s nothing to be concerned with, it’s probably something that needs to be rectified through an iOS update.

At some point last year, one of the iOS updates messed up this feature. It used to beep twice to indicate fast charging but after one of the updates it now randomly may beep twice or only beep once. I'll chalk it down to a bug but rest assured if you are using the charger that came with the 11 Pro you are getting fast charging.
