Why are we talking about turning off radios? The topic is internet connections. People claim that an idle 3g data connection does not affect the battery that much, but with my phone (an old, worn N95-1) there is a big difference. If I only use the data connection when the phone is in my hand and not in my pocket, I will have 3-5 bars on my phone when I charge it at night around 23:30, and if I leave the data connection idling, the battery will be dead at around 19. I tested this with nokia image exchange btw. It does nothing with the connection unless you take a photo, but still leaves it on all the time. People say that N900 will last the whole day with normal use. Well I'd like it to last a whole day with periods of heavy use. And automagically turning off the data connection if it's not being used could help that.
