My guess is that Sandisk is using a tiny battery in the player. The battery in the Fuze is just 550 mah. Why are they using a micro usb connector? While micro usb is better than proprietary, mini usb is much more convenient.
I wonder if the design team of these players actually use them? If so, why design players with such skimpy battery life just to save a few mm of thickness?
Imo mid sized players the size of the Fuze should have at least 50 hours of battery life, While smaller players around the size of the Clip+ should have 25+ hours of battery life.
