I recently got a new iPod Touch 4G and quickly updated it to the newest version of iOS. I know that most devices do not actually get there rated battery life, but my touch doesn't seem to get anywhere near the rated 40 hours for audio. I unplugged it the night before after it was fully charged and the next morning took it with me to school and by the time I got home that night I was already getting the "Less than 20% Battery Left" message. I basically only used it for music, on and off for most of the day. Wifi was on the whole time so maybe that is why and I did play some games for a bit. Is this normal battery behaviour or is there something wrong with my battery? Sorry for another thread about battery life.
