I have a 4 month old gen 7 iPod nano that is loosing charge whether the device is on or not. After a full charge I can turn it on and watch the battery drain from full to about 30% within 10 minutes and thats just having the device turned on; No music playing or anything. One thing I've noticed that hasn't been the norm prior to this. When I go to shut the iPod off completely as I always do when not using it, the little boot up wheel indicator spins as normal then the screen goes black indicating it's off. When I go to turn it back on I Hold the on/off/standby button until the Apple logo appears then the iPod boots up. When I turn it on after shut down now, the iPod goes straight to ON mode (home screen pops up immediately) instead of the boot up Apple logo. This tells me the iPod isn't shutting down at all. Still, the excessive battery drain is another strange issue. I'm guessing this is a software issue that just popped out of no where. I've done a hard reset. I've wiped the device via iTunes and did a reset, etc. Nothing seems to fix the issue. The only thing I've done differently is I used my moms car for a bit this afternoon and hooked the iPod up to listen to music while driving. Her car is an older model that requires use of the headphone jack instead of the 30pin/lightning connector for audio. I had the headphone jack and the lightning connector attached (to keep the iPod charged). This doesn't seem like it should cause issues but it's the only thing I've done differently with this device since I've had it. Sorry for the long winded post but any help is greatly appreciated.
