I didn't want to bother anyone with my doubts and suspicions so I ran a test on my 3g iPod for a week and here are the results. When in sleep mode, my ipod fully drains the battery in less then 30 hours. I didn't notice this earlier 'coz I used it a lot realy so it didn't ever sleep for that long for me to notice that and I charged it regularly. Now this concerns me a lot. Looks like the battery is givin up on me and it's just about two years old. When playing though, the battery life is OK. Anyone has the same issue?
