The Air has an Pi unit and an amp. Neither of which should be draining battery when unit is off. These batteries are large, should not be draining themselves just sitting on a shelf unplugged. There is no way to turn it on via an app, or Wake on Lan so what's using the power?
Also, I can smell when these units are charging. If you leave them plugged in, there's a distinct smell, and the battery is warm.
Typically, with Lithium you don't want the battery charging unless its drained. I'm worried about how long these things will last. I keep one of my Air's plugged in 24/7 because we use it a lot, but why is the battery constantly charging? like a trickle charge. I could understand say every 3 or for days maybe the battery tops itself up, but this is daily. Like what is using the battery when it's plugged in? and not plugged in and off?
