Does anyone know how the new overnight battery conservation feature works if you, e.g., briefly use your phone to listen to a podcast to go back to sleep at 3 AM?

The new feature where your phone will only charge to 80%, and stay there, only topping off to 100% right before you usually pick up your phone in the morning, is very cool.


However I sometimes have insomnia and while messing with your phone at such times is almost always a very, very bad idea in general, sometimes I will put on headphones and listen to a dull podcast or lecture to go back to sleep. I am wondering if that messes up the charging algorithm, if anyone has an insight into how it works.
