Hi, i bought my 8gb ipod touch 4days ago and i jailbroken mine right away but i noticed that the battery runs out reallllllllly fast. I never watch videos, i dont search on web, i dont look at photos, i dont go to itunes, the ONLY things i do are listen to music and play isnake. I would listen to music for like 1.5hr and play game for like 30min and the battery is half gone. Is my ipod a defect? or is it because i jailbroke mine... and also i never turn off my ipod. i put it in sleep mode <--is that a good idea? plzzzzzz helppp!!!!!
