The issue is not safety as lithium ions batteries and chargers are usually

Those smartphone users trying to conserve lithium ion batteries will not
charge above 80% or so. A Dyson doesn't offer the same degree of control
but leaving it on charge the whole time continually keeps topping up in
the most stressful way.

Citation? I don't doubt that the wall-wart feeding the bracket is very
basic, but doesn't the clever control stuff live inside the battery?
