I have a sansa fuze v2 (purchased it refurbushed a few months ago). The battery seem to need to be recalibrated, When fully charged, the battery drops from 100% to 10% in about 15-20 minutes, but then takes around 15+ hours to drop to 0%
Is this an issue with calibration, or does the battery need to be replaced.
if a replacement is neede, does sandisk sell replacement batteries?
I have no issues with desoldering and soldering.
