Double tap the home button (round button on the front) each time your done using an app and a bar should come up then tap and hold the icons on the bar and a delete sign will come up delete the apps off the bar (IT WILL NOT DELETE THE APP!! It just closes out off it completely!!) that will save you battery mostly and turn down your brightness almost all the way only having the brightness on a little still shows the screen in the sun and turn off your iPod when you sleep! Hope this helped!!
