When listening to music, slide the hold switch to On. This disables power to your iPod’s controls, saving battery life.
Step 2.
Disable equalizer
Disable the equalizer. Go to “Settings,” then “EQ,” and choose “Off.” The equalizer optimizes sound quality, but it also drains your battery.
Step 3.
Turn off backlight
Turn off the backlight. Go to “Menu,” “Settings,” “Backlight Time,” and select “Off.”
Step 4.
Create playlists
Create playlists in iTunes and listen to them on your iPod. That way you won’t waste precious battery power manually selecting the songs you like.
You can create a playlist on the fly right on your iPod. Choose a song title and hold down the center button until the title flashes—it’s just been added to your On-The-Go playlist.
Step 5.
Put iPod to sleep
Put your iPod to sleep when you’re not using it. Just hold the “Play” button until the screen turns off.
The idea for the battery grew out of Count Luigi Galvani’s experiments on frog legs in the late 1700s.
Another tip to save battery life that the video didn't mention is to make sure that "Sound Check" is turned off. This feature makes it so all your songs are about the same volume, but it also using quite a bit of battery life.
If you set equalizers on specific songs in iTunes, setting the equalizer on the iPod to off will use those settings. Set it to flat to disable the equalizer altogether.
