My Ipod won't charge before complete discharge, and it work only one hour with full charge: battery dead
The repair took aproximatively half an hour, most of this time was spent to open the Ipod. I follow all the steps on the Ifixit manual (on an android device) and all goes approximatively good. The plastic tools are not suffiscient to open the ipod i use a metallic tool but be carrefull it's easy to damage the device.
Be carrefull at the ribbon cable when you unstick the battery, it looks very "fragile"!
Sorry for my english (I'm french)
