SanDisk clip sport Equalizer and Battery life Also Firmware Release

Does the SanDisk clip sport Equalizer drains the battery faster on Custom Equalizer settings?

PS. Is there anymore firmware updates yet?

Very unlikely to be much difference.  Most likely its the same EQ just with slightly different coefficients loaded in custom mode to account for the changed frequencies.
