I had an extensive run on the RR today. I sent a freight engine down the line and left it running for about and hour or so as I was typing a report for work. I decided to end the run and grabbed my remote. It had powered down on almost a full charge??? After I turned it back on the engine responded normally, and I brought the train to a stop at the intended station. 
Is this normal for a CAB2 remote to go into a power saving mode?
