What is wrong with my poor little I-Pod shuffle?
All ipod rechargeable batteries have a cycle life. This means they can only be charged and discharged a certain number of times. If this ipod shuffle is a couple years old, it is very likely that your have reached the end of its cycle life. Otherwise if it is newer, then it may be a battery malfunction. This can be caused by any number of things, and is often (in apple products) cause for a recall. The would most likely do a “soft recall” where they post about it on a semi-obscure page on the official apple site in hopes that most people experiencing the problem will not find that it has been recalled. It is this same principle on which Apple makes their ipod batteries non user replaceable — so you have to buy a new ipod when something like this happens. So anyways, do a google search for potential recalls of the generation of ipod shuffle you have and see what turns up. More than likely though it is just simply time to buy a new one.
