settings question

On the Sansa Clip under settings-power-auto power I get something that says 1mins with a little bar above it. Can anyone tell me what this means. Also is there anyway to tell how much battery power is left exactly besides the little icon on the top right of the screen.


The setting refers to how many minutes the device stays on before shutting off in the case the music is paused or reaches the end of a list.

You can use WMP11 and right click the device (MTP mode only) to read the device properties and get the estimated percentage battery remaining.
