Hi I'm new here and I have some questions. I have a 2g ipod touch 4.0 jailbroken. Recently, my iPod's battery has been going crazy. When I fully charged it, it went from 100 to 60 in about one hour. The strange thing is..I probably only used the iPod to drop only about 5%. It seems like the battery constantly drops when the screen is black..you know, when i press the button on the top left. After i start using it, the battery starts to climb back up slowly. What is going on? Is there a way I can fix this? Thanks.
