I have noticed no difference but I'm also one of those users who only sync while their phone is charging (especially because I have a synced computer on less than half the time, so it's a waste of energy to have my phone constantly seek for my other devices online), so I don't know if my experience is relevant if your syncing is constant.

I like to fine-tune my control based on charging in case I experience data loss once in a blue moon, to eliminate panic about the loss immediately daisy-chaining to other devices. I guess I don't understand/trust how file retrieval through the trash system works...
