I just purchased one (IPod touch) 5th generation (pink color) last week. I have already updated to the latest OS (6.1.3 I believe). Definitely there is a battery problem. I do not have any apps on it, First time charged the device, 8h later dead!. Turned off location services, bluetooth, WIFI everything, reseted the device, charged back on, same thing, after 8h, dead. I also tried this: Charged the device completely at around 10 PM, turned it off, in the morning, I could not even turn it on, it is dead! I am not going to exchange, because how am I going to know if the one they give me would work! I am taking it back to the store!!
