What is best for the iPod and battery life... Pressing the sleep button or turning it off? For now when I'm done using it and am not playing music, I just press the sleep button, but I'm afraid that doing that will suck up battery.
Turning the iPod off is by the far the most power efficient than just putiing it in sleep function.
The sleep will put the iPod in a very low power state therefore consuming less power, but leaving it in long states of sleep will eventually drain the battery
