Airplane mode vs. no notifications, no mail fetch

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.

 

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!
