The power indecator doesn't decrease over time of operation.

It reads full power then after a while of operation it reads empty, but still works usually I turn unit off wait a minute turn on again. Reads ok till it isn't. Again I reset. When it does this I don't idle when not moving I turn off. I wish I had a better more mechanical register maybe connecting through charger port.

Any one have a clue of what im talking about?
