battery life and storage

A few suggestions:

Battery Problems?

    Make sure you are turning off the player when you are done listening, not just leaving it on Pause.

    Maybe check your Power Saver Setting.  I use “5 Mins”.  Will autimatically shut off the player if left in pause mode for 5 mins

    Maybe try using a different micro USB charging cable. I always get best charging and data communication results with the micro USB cable that came with my Clip Sport.

2000 Song Limit in Music Database?
    Maybe take a look at all the replies in this long message about beta Firmware 1.28 in the SanDisk Forum for Clip Sport

    I think the 4000 file limit allowed in the beta firmware is a good match for the file capacity of a 32gb micro SD card.
