    I want to charge my iPod touch 5g overnight. Will this wear out the battery in anyway or will the iPod not accept the power?

    It will just charge normally like it's used to, nothing to worry about. However, it's usually better to run down the battery to red (<20%) before charging. Furthermore, ensure that you completely drain the iPod once a month (use it to 0%), to ensure a power cycle charging.

    What you said is true except for the part about running it down to red. Batteries wear out a little whenever they are discharged then charged, so running it down then charging it is not good. The point of running it to 0% once in a while is to calibrate it.

    i read somewhere that you shouldn't let the battery goes down to 0% or at the point that you couldn't turn it on.

    Little below 20% when it starts warning you. Go recharge, dont wait until the lighting signal appears, its not good for the battery. Nevermind the charge counts.

    Lithium batteries, like those in modern laptops and iDevices, should not be fully discharged. Doing so causes them to basically "eat" themselves. When they do this they permanently loose some of their total capacity. The longer they sit empty, the more loss there is. The older styled nickel based ones are the only ones that should be fully discharged between charges.

    i'm trying to adhere to the 80% / 20% rule for longevity.

    Fully discharged as it the iPod's internal clock stops. iDevices have a built in safety that turns off the device at about 25mha to prevent this. If you ever go through that last 25mha, you risk damaging the iPod's battery.

    those tips of batteries create a memory over time and if you charge it from say %50 it will become the new %0 but this happens over a long time

    People have a misconception of lithium batteries. Lithium batteries do not have the memory effect and do not require the deep discharge. Any reduced capacity over time is due to aging.

    The Batteryuniversity site is a great site that talks in great detail about all things battery. Including memory, differences between types of batteries, charging protocols for each, etc.

    It is worth a read if you are really interested.
