My offshoot rant is that it should be easier hold devices at a longevity charge.

I want some gadget that keeps my essential gear in a long-term maintenance mode. Oscillate it 20-80% or keep it at 50%, whatever is optimal.

Every time I've looked into building something like this it seems like there's no standard reporting of charge level over the wire. I would waste a genie wish on this to have it in the USB spec and widely adopted.
