You have headphones on in your car, listening to music, while you’re driving? I hope you’ve checked your local laws because that is illegal in quite a few countries. It’s also a very niche example as most people would use the car stereo instead of headphones.

How often do you charge your phone and listen to music at the same time? And is that really something you cannot compromise on?
One example - I charge it when using it for navigation in the car while at the same time listening to music.
