The iPod uses a lithium-ion battery. Any battery, including the iPod’s, will eventually wear out and no longer provide the power it once did. In my research, most lithium-ion batteries are rated for 300–500 charges. In this context, a charge can’t be precisely defined, but it does include a full discharge and then a full recharge. A partial charge doesn’t “count” as much, but the precise relationship between amount of charge and how much that charge “counts” can’t be specified. Batteries like that in the iPod actually last longer if you don’t let them fully discharge before you recharge them. Frequent “topping off” will not reduce the battery’s life and in fact is better for your battery than letting it run very low on power before you recharge it.
Every 30 recharges or so, do run your iPod until it is completely out of power and then perform a full recharge. This will reset the battery’s power gauge, which tends to get more inaccurate if the battery is never fully discharged.
It doesn’t hurt the battery to do frequent and short recharges, such as by placing the iPod in a Dock every day after you are done using it.
However, you should make sure to run the iPod on battery power for significant periods of time. If you constantly run the iPod from the power adapter or while it is in the Dock connected to a power source, the iPod’s battery’s performance will degrade.
