I know there have been a lot of threads about the battery life on the ipod touch but I don't remember seeing my question somewhere. after jailbroken my ipod touch with 1.1.1 firmware I thought that the battery life time was quite short even with wifi and ssh turned off. So I thought maybe there was something wrong with my battery. I restored my ipod touch to the official 1.1.2 firmware and now the battery life time is much much better. when my ipod was jailbroken I set the mail app to check email automatically and I would like to know if this could be the reason for the battery to decrease so fast. I think even if you put your ipod in sleep mode it keep the connection alive. anybody experienced the same thing or I am just hallucinating. If I have time I will jailbroke again my ipod but I would like to know if someone else had the same situation and if turning off the automatic mail checking could improve the battery's life time. I miss my jailbroken ipod with mail app.
