I’m not sure I understand this argument. Why can’t users simply use the mouse wirelessly even if it’s possible to use in a wired way. Are you claiming that people would end up leaving the mouse plugged in, like they do with the trackpad? If the point is that using a wireless mouse is a better experience, then why wouldn’t people use it wirelessly except to charge?

I have an Apple keyboard and trackpad that I use at my TV wirelessly but have benefited from the ability to use while charging a few times when the battery died. Doesn’t stop me from using it wirelessly 99% of the time because the experience is better.

By the way, I have an older phone I leave plugged in all the time by my bed, the battery life on it has deteriorated but it works perfectly for music.
