How To Extend Your IPod's Battery Life

PCWorld has uploaded a video about How To Extend Your IPod's Battery Life. Apple claimed that IPod can be used for about 24 hours (up to) before it needs to be recharged (fully empty), but after some time, it will degrade. You won't get 24 hours again, but probably less than that. The video shows you some tips on how to extend your IPod's battery and maximize it between charges. But, look at the notes below:

Rechargeable batteries have a limited number of charge cycles and may eventually need to be replaced. Battery life and the number of charge cycles vary by use and settings. See www.apple.com/batteries for more information.

There's also some tips on Apple's website (here and here) on how to extend your IPod's battery (actually IMHO, PCWorld's video is based on what information is given here, but they made in visual form).
