Recently my ipod touch 2nd battery's life has been decreasing greatly. From full charger it'll die within 3hrs only listening to music. Anyway now it doesn't turn on at all meaning that it won't go into dfu or restore mode. My comp obviously doesn't recognize it. Plus I don't have warranty and it's jailbroken so I can't take it to apple because it won't let me restore. So is it time for a new battery? or is it something wrong with the ipod itself?
