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.
