Hello. I got this warrant replaced ipod touch a while ago which came with 1.1.3. I upgraded to 1.1.4 for a few months but recently, the battery life has been really bad. I go on the touch for maybe 30 minutes of just playing the occasional game and browsing files and checking installer for updates and the battery life goes to 80%. This has been happening really often now and I even restored and installed only the necessary apps but the battery life is the same. I also have mobile stacks installed FWIW. Also, I have a plastic shell case on the ipod and when charging, the ipod gets warm sometimes. What's is going on? Is this covered by the warranty? thanks.
