My iPod Nano 4th generation will not charge correctly.

Hi

I know how you feel,iv had the same thing happen to me a couple times and I found that replacing the battery usually fixes it

Once these old iPod lithium battery’s are dead for some time they don’t like to wake up very much

Just to confirm it’s the battery I would try and restore using iTunes and if that doesn’t work

Replace the battery however in these iPod nanos it is easier said than done by not Impossible if your up for a challenge and you know how to solder

Hopefully this answers your question

Thanks:-)
