Does wifi always stay on?

[Dougfnj]

just curious If wifi is on in settings does it always stay on until you turn it off whether you are connected to the network or not? I seem to lose a lot of battery life quickly unless I manually turn of off in settings, whether my touch is turned on or not.

If you put your iPod Touch to sleep, the wireless connection will turn off automatically after about 30 seconds or so (you can ping your iPod Touch and verify). However, if you have Mail set to automatically check, it will of course kill the battery using Wi-Fi. If you're in an area where you do not have a wireless connection, you should turn Wi-Fi off. Otherwise, it will waste power just trying to search for a hotspot.

i believe it turns off when the device goes into sleep mode....thats what mine appears to do.
