Who was it that said while you tablet is connected too your TX or (Remote control) it will not drain power from it...
I have the new HTC Nexus 9 LTE and it go's into charging status upon connection too TX therefore draining it's power.
Awesome pad but dose get hot underneath sometimes though.
I have the same issue. Does not seem to affect all tablets (iOS tablets for example don't enter charge mode). The nvidia shield does.
