Are there any kind of apps for an ipod that can boost your battery so it doest die as fast?
No, you have to take precautions yourself. Dim brightness, disable 3G, keep in moderate conditions, close background apps, bring portable chargers, etc.
i've been searching and haven't found any
No but there are apps that give tips on saving battery life
Yeah it's called Battery Boost Magic and it cost $0.99
There's nothing for it, the only way is upgrade your iPod or iPhone every time... The new software it's out.
Might want to change the brightness in settings to save some of the battery. I am told you can buy a new battery if the current battery you have has gone bad.
