hey guys i just got my ipod touch 4g a week ago and i am really dissapointed in my ipod touch's battery life. it's supposed to go like 20 or something hours just listening to music right? but when i listen to music it asts like 4 hours max. i set teh brightness on low, i turned off wifi, i turned on airplane mode. i used backgrounder to make sure that no apps are running in the background and it still sucks. i was listening to s song then i stopped it and put it in sleep mode b/c i had class then when i turned in on 1hr later, the battery life was down 5%, just on sleep mode. i am very dissapointed, my zune 30g first generation has better battery life that was playing music AND VIDEOS. i am only using this for playing music and it don't even lasts long. does it last long for anyone else? edit: i am jailbroken btw, but i don't have alot of addons on the ipod, i mean if it ws supposed to last 20 something hrs with music playing, then at worst it should last maybe 7 hrs. but it don't even reach 4 hrs for me.
