...never ending question....
when the phone has active "data connection" but there is no "DATA EXCHANGE" the is more battery consumption or not ???
Many thanks in advance !
Yes, because it has active connection, which means it is connected
even if there is not data exchange ?
Well...keeping connection established mean sending and receiving packets...so it should consume battery...i don't know how much...but something for sure...

Hi All,
Hopefully someone may help with my query.
I have the HTC Wizard running on O2 UK latest ROM, the cell is unlocked and running another providers card.
The email is configured to check for new POP3 messages every 60mins when I am away from the PC.
The problem is that when it connects the GPRS and checks for messages the GPRS stays connected.
Other cell phones I have used will connect and autodisconnect after checking.
Maybe the GPRS is connected but not sending/receiving data during the idle period?
Can anybody shed some light on this?
Cheers all.
True- This also happens after you send/receive an MMS!
Any way to auto disconnect would be good.
GPRS
After more research I find it doesn't matter if the GPRS is active, as long as it is not sending or receiving data no charges will apply.
Still worrying though and will need to check bill!
thats is a big problem, the baterry life go away....
there no 3º program to do this? no one knows?
disconnect script
Maybe something like this ,modify the script to check and disconnect the GPRS say 5mins after checking your email.
chalky.
Solution
after the send/receive of mail or mms, if you hold the end call button the GPRS will disconnect.
hi
How can i monitor how much data i've used (not wifi)
I've got 500mb a month, and while i'm sure i wont use this, i want to keep tabs and reset each month
is this functionality built in?
cheers

I managed to rack up over £100 of data charges before I realised that my network settings (buried away down start->connections->connections->advanced->select networks .... obviously !) were set to use the cellphone connection by default. It was therefore using HSDPA even when wifi was connected. I proved this by downloading an app called GPRS Traffic Monitor. It's very basic but it monitors your GPRS/HSDPA traffic. I've now switched the default connection to be "My Work Network" instead of "Contract Internet" and traffic monitor now shows no increased data usage while the wifi is connected.
I've also noticed (although not scientifically tested) that if an application gets a connection via HSPDA before the wifi connection is established then it continues to use HSPDA and doesn't switch over.
Maybe everyone else knows all this but it was all news (and very expensive) to me.
Cheers,
David

hie have you got a link for gprs traffic moniter, either freeware or paid thanks
www.efficasoft.com. Costs about $10. BTW this is just the first one I found and there may be better ones out there if you have the time to do some google searching. However, this one does seem to work and a couple of other I looked at were fine with monitoring GPRS but couldn't seem to handle HSDPA - this one seems to work fine though.
At the moment I'm still trialling it and if nothing better turns up in the next couple of days I'll register.
Which version did you select?
I can't get the efficasoft cab to install (it keeps reporting back as installation unsuccessful).
Any clues?
I think I downloaded GPRSMonitor_PPC12.cab - I'll check tomorrow and repost if different - I'm just going out now.

Are you sure that you don't have some other setting wrong?
I have cellular network selected here but have issues with it dialing with wifi or activesync connected.
I have just set my mobile web connection to 'always on'. I've done this through the 'Advanced Config' app - GPRS auto attach: Enabled. Will this take more battery? I've read old posts for other phones, that claim this does kill battery but I've also found a post in this forum that says it doesnt! http://forum.xda-developers.com/showthread.php?t=546359
I have had endless trouble with my data connection - not being able to connect to internet, google maps, email etc and the only way to fix it was to either toggle airplane mode on and off or to actually soft reset. I'm hoping that having the GPRS auto attach will solve this trouble.
Any thoughts?
I'm doing experiments now with the battery life.
I charged phone to 100% and left in standby overnight with mobile web connection running. When I checked this morning, after 9 hours battery life was at 98% (received 1x sms and 1x email during the night).
Mobile web has now been connected for 17.5 hours and battery life is at 79%. 22mins device usage, mostly internet. No calls today and just the 1x sms and 1x email (Im not very popular - as is evident from the lack of replies to my post )
I will do the same experiment tonight with mobile web not connected.
Hi
It doesn't drain the battery. You have a permanent connection to the network anyway to receive phone calls. When you "attach" a data connection you're phone obtains an IP address and keeps it. To get an IP address requires an initial bit of talking to the cell and once it has it, that's it, it's doing nothing unless being actively used. If you disconnect all the time you will use more power as it costs power each time you have to negotiate for an IP address. Networks also prefer the connection to remain on as it cuts down on network traffic.
The only way your power is used more is if you have an application that is using the data connection continually.
Regards
Phil
Thanks PhilipL, exactly the answer i was hoping for as my connection seems a lot more stable since enabling auto attach.
Hi guys,
I have recently moved from symbian platform to WinMo. I do have a question regarding data connection. Does it ever auto disconnects? (for example in my old N95 if I clicked sync in my mail application, the phone would connect, download new mail and then auto disconnect when the job was done)
Also the phone would disconnect from data connection after closing app that was using it.
Now with my HD2 when I sync email, refresh weather etc the data connection stays on. Do I have to disconnect it manualy every single time so it doesnt drain my battery? It is very annoying since I have to do it manually very often.
Please advise... maybe I am missing something...
Cheers
Pete
Hi,
There's a few threads on here on data connection disconnection. There is also a hints & tips thread right at the top of this page.
Use this tool to find what you are looking for..http://www.google.com/advanced_search?q=+site:http://forum.xda-developers.com&hl=en&lr=&as_qdr=all

install the 1 min disconnect tweak thats on this forum.
if you only set emails to check automatically it will disconnect ok using the above tweak but if you have weather and/or twitter apps connecting to update for some reason it will not close the connection at all i have told htc but never heard back
The only real reason for disconnecting a data connection is if you want to prevent unwanted costs associated with data exchange.
If you're in a weak signal area you can save battery by switching the connection band to GSM rather than 3G, but in a strong signal, 3G is more power efficient.
An open, but quiescent data connection has little or no effect on battery life as it's simply using the network infrastructure; battery usage only occurs during actual data exchange. So, if you turn off all the auto-update features and set email polling to a longer interval you should be OK. Kind of defeats the purpose of the device though

From my experience all Symbian devices and the iPhone auto disconnect from the network once the data connection is no longer needed. They also reconnect in the blink of an eye. It kind of irritates me that Windows Mobile doesn't allow you at least the OPTION of doing so. It's particularly annoying if you're connected to a speaker and can't get 3g as there's a constant noise going off. I also think it can't be great for your balls having that connection constantly active! It's not HTC's fault though, just I think a result of Windows Mobile being inherently quite archaic...perhaps Windows have just overlooked it.
There's a great free app HERE to tweak the WinMo connections for individual apps. It's a must have for me.

This really isn't a problem, I've seen N95's that retain their connection at all time (and some that don't) and to be honest it just makes your handset a little quicker.
WMLongLife is the nuts. You need it.
Thanks for the link, I pay per minute on my connection (rather than data transferred) so an open connection is not good for my bank balance
Hi! I just started getting this message constantly: "Connecting to T-Mobile Data, Connecting to GPRS" around every hour or so (along with an audible alert which is the problem). I don't know what it means, or how to change it. I don't seem to have any problem using the phone, but the constant audible alert (ie. at night) is what i would like to at least stop. I do not have a data plan, I only connect to the internet with a wireless connection. Thanks so much.

Go to settings - cellular and disable data conection
Ok! Thanks, I will try it. Is that under "wireless options"? Thank!!!

No, settings - cellular and inside cellular you will find data conection and set it to OFF.
OFF means you will only have internet conection and sync only when you turn wifi on.
