iPod less than 1 year old battery life My less than 1 year old iPod touch (A1421) lasts about 8 hours with no use other than listening to podcasts. 

Is this level low enough to justify an in-warranty battery replacement? 

If so, do I need to do anything to provide proof or will they just set it to play and see the power gone after 8-9 hours?
It may be worth backing up your iPod and performing a factory restore. We recently had an iPad that would discharge to flat in around 8 hours, where the rest of the set would still be going strong a couple of days later. Restarting the unit made no difference. The last thing we decided to try before returning the iPad to our supplier was a factory restore, and it was this that returned the iPad power consumption back to normal.
