    Hi everyone,

    I wanted to know if battery life is affected equally the same whether my iPod Touch (4th Gen.) is in airplane mode or if it's not in airplane mode but notifications are off, there is no mail fetch going on, nor are there any apps running that would be using WiFi (i.e. accessing the internet)(but WiFi itself is still left on). It would seem to me that if the iPod is in standby and is not accessing the internet it would use the same amount of battery than if it was in standby with airport mode on (And I suppose it would be the same for the iPad too?). I'd like to stop having to use airplane mode, that's why I ask!

    Thanks.

    When in airplane mode all radios are turned off. So nothing will be fetched, this includes WiFi. You battery life should increase in airplane mode as you are not using the radios.

    I assume that you are only using airplane mode on a plane right? If that is the case then use it or turn it off as directed by the flight crew.

    Thanks for the reply. I put the iPod in airplane mode almost all the time, mainly to save battery power. But I noticed that if I don't put it in airplane mode, but have notifications off and mail fetch off, then the wireless signal icon takes a moment to reappear when the iPod comes out of standby mode. This had led me to believe that maybe the wireless radio also goes quiet or turns off in a way, when it is not being used, even though wireless is on and the airplane mode is off.

    Sorry if that's confusing!

    It doesn't go completely quiet. It will still send and receive packets occasionally to let the base station know its alive.

    Not from what I have seen. WiFi is totally off and is not connected to any base station. I have tried this with my 3G and it stayed disconnected.

    Source?
