"Standby mode not working properly on iPhone 15 since updating iOS to 18.4.1: Standby mode is no longer working when charging on a MagSafe power bank. It certainly used to. It only works now if the charging cable is directly plugged into the phone. That’s annoying as I have a flip up power bank which doubles as a nightstand."
