Guest Adeboy Posted March 8, 2004 Report Posted March 8, 2004 Trying to get some brownie points from my boss here. He's just bought a MPx200 running on Voda. :) I want one! He gets webpages via GPRS but when he closes the web page the GRPS connection doesn't drop. Any way to setup phone so that closing lid or closing web page shuts down the GPRS connection. He's not bothered about cost, just that GPRS saps the battery. Ideas?! www.msmobilenews.com Rocks!
Guest Shuflie Posted March 8, 2004 Report Posted March 8, 2004 Tell him to press the red hang-up button, that cuts the active GPRS connection. And dont worry about the BIG 'G' shown at the top of the screen, that just means GPRS is available, not that you are connected to it. When a GPRS connection is active a 'G' appears on the signal strength meter on the home screen, when GPRS is available you have the big 'G' on its own at the top of the homescreen and on the signal strength meter on the external LCD.

Guest scott2eyes Posted March 8, 2004 Report Posted March 8, 2004 He's not bothered about cost, just that GPRS saps the battery. I could be wrong, but I don't think that having a GPRS session open actually uses the battery when you're not sending/receiving data- at least, not any more than having the phone receiving a signal but not in a call (ie. the state the phone is in when you've ended the session.)

But then again, perhaps because of the nature of GPRS extra battery drain would occur - GPRS sessions can have a tendancy to drop off (round here they do anyway) and the information that feeds the display indicating that GPRS is available might be constantly updating. :? I think I've just changed my mind. :wink: Matt.
Guest awarner [MVP] Posted March 9, 2004 Report Posted March 9, 2004 Being connected to GPRS will drain the batery faster than not connected at all. As with making a call the phone is connected and still has to ping to confirm this.
Guest scott2eyes Posted March 9, 2004 Report Posted March 9, 2004 Being connected to GPRS will drain the batery faster than not connected at all. As with making a call the phone is connected and still has to ping to confirm this. But it has do do that any time it's in service, as it's checking which cell it's connected to, whether it's the best one available, seeking service when it loses signal etc. etc. I would think that keeping a GPRS session open (or checking for GPRS availability) would be a straightforward part of this, as it's still a part of the same GSM signal (isn't it?)
Guest awarner [MVP] Posted March 9, 2004 Report Posted March 9, 2004 Don't forget when using GPRS you are constantly connected and the ping is the data charge. In normal GSM mode you re not, it only scans the network connection at intervals.
Guest scott2eyes Posted March 9, 2004 Report Posted March 9, 2004 The thing is, GPRS uses virtual connectivity, which (as I understand it)means that you're not "connected" just because you've got a session open. Check this site, under "Spectrum efficiency"; http://www.gsmworld.com/technology/gprs/intro.shtml#2b Now, admittedly, I don't know nuthin' about nuthin', but the implication to me is that not only does having a GPRS session open not use more battery, but in immigrating traffic from circuit-switched data it might actually use slightly (and I do mean very, very slightly) less battery... :shock:
Guest martin Posted March 9, 2004 Report Posted March 9, 2004 Once you know what 'always-on connection' means it makes a lot more sense :) You are right scott2eyes. When surfing the web there is no dedicated connection across the GPRS network. Also having an active PDP context (small G) won't mean the battery will be used any more than normal. This is because of something called mobility state which will drop to standby after a short time (ceases cell update). Non active PDP context+standby and active PDP+standby are much the same. Only location areas are updated. Hmm I must lay off the beer :lol: Posted from my SmartPhone!
