I have a 16 GB ipod on FW 2.2.1 jailbroken, and the is a major issue with the battery life. when listening to music, the battery life is tolerable, but still drains much faster than usual (lasts around 4-5 hours), but if i watch a video or play any game for more than 5 minutes, the battery meter shoots to red and shuts itself off. If i quit playing when the meter is red, after a while the battery meter shows green again, close to 100%. if i let my ipod go to red and continue playing and it shuts off automatically, the battery meter shows green again as well. so, I am unable to use my ipod for anything other than music. SSH, wifi, etc is off as well. my brightness is always at the lowest possible setting too. Any help?
