Hi sorry for this really stupid question but just wanted to clarify something. When I plug in my XR and say remove the lightning cable after 5 seconds, there is a delay of about a second before the phone recognises that its no longer being charged. That's not the case with my iPhone 7 that instantly shows that its no longer charging. Can someone please verify if this is normal? Just plug in the XR for 5 seconds or so and then unplug - does the battery indicator instantly show its not charging or takes a second?
