Hey, I got my ipod touch in december 2008 and I jailbroke it recently. However, the battery wasn't lasting very long; it lasted around 4 days. In these 4 days, for 3 of the hours, it was being used constantly. I installed SBSettings and decided to turn off SSH and the wi-fi when I'm not using the ipod. How long should a battery last in sleep mode? Thanks.
