Incorrect. My first point was that the iPhone XR is not the first phone that only has to be charged once or twice a week.
My second point was that you can also extend the life of any phone with a battery case. And yes, after you install a batter case that uses pass-through charging there's essentially no difference.
> I believe this line of reasoning also explains your other points satisfactorily.
OK and I'll assume that your misreading, your misunderstanding and your incomplete response to my points stem from an intentionally weak interpretation.
