iPod touch 5thgen losing battery while turned off??

I've noticed upon receiving my new 5th Gen iPod touch that the battery life seems ridicuously poor. I have to charge it almost every day even with no apps running in the background, bluetooth off, no fetching, wifi off when not in use and only playing music for about 40 mins a day. Another wierd thing is that my ipods Usage says 15,740 days, 23 hours and Standby says 15,741 days, 10 hours ... I only got this ipod at christmas time!! Also, my messages app sometimes freezes after a few seconds of typing and I have to reset again and again to ever get the message out.

Some help would be greatly appreciated 🙂
