Bull. I am doing it right now with the real hardware on a daily basis. It's the whole point of the device. Nokia said "our goal is to make it last a full day" and it does. Our technology is already at a point where we can enable this.

Go ahead and file the bug if you want. It'll just get closed as invalid anyways.

And you already can disable the 3G radio at will. It just doesn't do it automatically when your last open app is closed. Besides, there are other apps in the background still using it - e-mail, IM, phone, etc...

No. It wouldn't go over well....which is why their message is radically different - they're saying that you can remain online all day.

What experiences have you had? How long does your battery last, and under what conditions (usage patterns)?

Oh yes, it easily survives the day with radios on. Definitely better than the fruity or green-robotic competition.

At the summit my device lasted only until just after lunch with wifi on all morning. Granted though I was using the screen on a lot at the summit.

Now that I am at home my device had used almost half its battery by 3PM with "frequent" 2.5G/Wifi usage. Not abysmal, but it could be better.

remember pre-release software that could all change on the final shipping version

There's a chance that wifi had to be set to a lower power saving mode. I know at home that I had to set it to intermediate power saving instead of maximum because of problems with the connection... even though my old tablets on maximum weren't an issue.

The vision you propose is very compelling zerojay. The only problem is our technology is not at a point where we can enable this. The battery simply will not last a full day with the radios on and hence the N900 still has to act like everybody else it is competing with and disable unused devices.


So, back to the original point in this thread. Is there a way to automatically disable radios or should I file a bug?
I must be missing something here. Last I checked on my Android MyTouch there's always a connection open. My BlackBerry Bold requires an active GSM or Wi-Fi connection for internet and Push services since they all go through BIS, Windows mobile 6.5 disables the data features until an application requests them, but the Radio is still on with an active connection on EVDO in this case. The only time I can think of any smart phones completely disabling the radios is when your BlackBerry gets below 5% battery.

I understand there are power saving features on these things but they're never completely disabled unless there is user input, or am I just confused, it sounded like if you weren't using the radio for something you want it completely disabled?

While I agree with the idea on some level...that would be a lot of calls to voicemail and late SMS messages.

I have an ARM SBC with GSM modem. I've set it up so that the pppd daemon is always on and ppp0 interface is there. Whenever there are ip packets to be sent the pppd daemon initiates the chat script and activates the GPRS connection. There is also timeout after which the pppd shuts down the connection. See pppd "demand" and "timeout" parameters.

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.
