iPod Touch 4 既電量問題.. (( 20點

to save energy, you can turn your brightness lower, sound lower and charge for a full cycle( 0-100%) every month, the ipod shows full charge but it still has a lot of space, you should charge for 2-3 hour everytime.

With your games, ios4 has multitasking so it does run in the back, to shut it, you cant do it like how the first answer taught you, you can do it by pressing the homebutton twice(fast) so the multitasking bar comes out, hold one of the apps for a longer time( like how you do it when u rearrange ur apps in the front screen) and you will see the app icons shake, press the red button on the corner of the app and it will shut it down. this helps keeping battery life also becuase multitasking is not inuse.

hope you understand it!
