I must know: Is it bad to let iPod die all the way before recharging?

    I am always getting mixed opinions on this and I would like to know the answer once and for all. Is it better for the battery to simply charge when the Touch says it has 20% or 10% power left, or is it better to let it completely die before plugging it in?

    To be honest if you kept your ipod touch for years and years then i'd be fiddling around with battery draining etc, but seeing as you likely won't use it/will have replaced it in 2 years you will not see any sort of wear/tear that is significant...

    Long story short

    Charge it when you want

    Modern batteries have life estimates based on charge cycles. Charge cycles are defined as full discharge followed by full charge (or vice versa.) A half discharged battery being charged to full again counts as half a charge cycle. So it doesn't matter.

    In the past, there was a problem with "battery memory" and this could be remedied somewhat by discharging and charging in certain patterns. The batteries used in Apple's products don't have the battery memory, but all rechargeable batteries degrade with use.

    Again, it doesn't matter. Charge it how and when you please.

    Letting your battery fully drain is one of the only ways to get accurate power meter readings from items like the iPod touch, or many laptops. It is what they call "calibrating" and doing it every so often is actually a good idea.

    It prevents the device from suddenly powering off (because it's system controller doesn't know the actual status of it's battery power and shut down) or showing inaccurate power meter readings. Some say it helps with battery longevity, but as others have said, it likely doesn't matter.
