iPod 4th Generation Battery Life
I have had my iPod 4th Generation since its release date. I've had no problems with it whatsoever and have taken good care of it resulting in minimal scratches and similar markings, no water damage or overheating or shock damage etc etc. However recently the battery life has become a problem. Usually I will charge my iPod and other Apple products sometimes overnight but also throughout the day, but even after a full night of charge my iPod's battery life won't even last the length of a song without claiming to have "no charge".
I understand that my warranty is way, way out of date, but as this is a manufacture's fault and not damage caused by myself, is there anything Apple could do to help render this issue?? Any kind of software I can download to it or some kind of repair procedure I can send it away on? Thanks!
