Battery Mini Blender My IPod Mini Battery Has Gone From The Sublime To The Ridiculous?

My iPod mini battery has gone from the sublime to the ridiculous? - battery mini blender

This is one of the first generation. Mini. Calculate I for four hours until it is full. Can I give it to the computer thought it will load and connect the charging reconnect! I do not know in the middle of the load disconnect period, as I have heard that the ruins of the battery. But then he still has to complete four hours, if I have not heard it all free!
And if she does pay some. one hours. Sometimes less.
Is it me or is it pathetic?
