drained battery

I used the Fuse continuosly until the battery was drained.  Now it wont power on or recharge.

I plugged it into a usb 2.0 and usb 3.0 port, no luck…

Is this how it ends?  Did I blow this fuse?

It works again.  I plugged the fuse into my notebook and its recharging.  It must be old age.

This might be slightly off-topic, but … My 8 GB Fuze is 2 years old.  I only use it for the FM radio (much better than Sony’s Walkman radio).  It had been working about 20 hours before needing a recharge.  Suddenly it won’t fully recharge, and dies after 4 or 5 hours.  Is this “normal old age” or should the battery still last as long as it did originally?

I can’t help but my fuse is collecting social security and the battery still lasts for 12 hours
