How can I make my iPod touch battery longer?
Keep running your battery full to empty I don't know how but it works, also turn your brightness below half and turn all notifications and things like that off
Why would you want to make it longer? I'm sure when apple designed it they made it the correct length to fit properly in your device.
By a battery operated charger there sold at office max and ya just put it on your iPod werever since it's battery operates and it'll last forever lol;)
Turn on Auto-Brightness.Turn Off Location ServicesTurn off Equalizer
Double click the home button, hold down on one of the boxes until they all shake, and close out of all of them.
I say turn the brightness down a little bit
