Hello! I have noticed that my iPod Touch 2G 64gig battery life has recently decreased in length from around 25 hours play time to around 12-13 hours. While this is still an awesome amount of time for an iPod to last, I would prefer it lasted its original length. Let me note the following things: * this does not seem to be related to any recent iOS upgrades * I am extremely anal about battery life and always pay close attention to how long it is lasting * I run the iPod in airplane mode. Always. (therefore wifi is always off). * Currently, I use the iPod for music only. Rare use of games and apps maybe once a month and no App/game usage since I noticed this battery issue. * I have seen this problem on my iPod once before, but the problem disappeared after a firmware upgrade. A recent firmware upgrade did not make the problem go away. * rebooting the iPod does not make the problem go away Anyways, I am wondering if anyone knows a solution to this. Also, has anyone tried "reset to factory settings" on an iPod Touch? I don't know what this feature does. Will it erase my notes or calendar or delete my once-in-a-month Angry Birds progress file?
