I really like the magnetic charging port plug adaptors for situations like that, but personally, if I’m jumping up and down from my desk at work or something and have my phone plugged in, I’ll just leave it on my desk while I’m away. And if I’m not coming back to it for a good bit, the extra half second it takes to unplug my phone is more than worth the more efficient power transfer, imo.
But to each their own.
I think eventually storage density will scale beyond data size growth and we will reach a point where even videos are nothing and then distributed video hosting will be possible, but it’s probably a ways off. Think about how much it took to just store text files or music like 30 years ago vs now. We aren’t there yet but it may happen.
