Some questions about the "ALWAYS ON" GPRS connection in WM2003 (device = imate aka XDA II)
1. Does it consume extra battery life if the GPRS is alawys on?
2. When I'm connected but not actively doing anything (upload/download), does the device keep communicating with the service provider? i.e. sending control information back and forth even when i am actively not using it?
3. If the GPRS connection is active, are there any chances my phone reception or the phone's ability to get a phone call/SMS/MMS is adversely affected? I dont want people not to be able to contact me or send sms/mms because my phone is always connected on GPRS.
4. Once the GPRS connection is made, and i'm done doing my "thing", how do I disconnect? Cause currently I have no way of disconnecting.
1 yes like your phone use more power when you speak in your phone it use lot more power then not using it
2 a bit not too much
3 it should not
4 www.GB-SOFT.cz/xdaII should add some features

Mind you, I use an MDA I.
as far as I know, the only way to get off and stay off GPRS is to go to settings->system->memmory->running programs and close anything that might use it (mailbox, IE, etc...)
If the signal indicator says it's connected to GPRS, then yes, you are actively connected to the tower/cell network. Sending info constantly, I don't know?????
GPRS effecting other network connectiveity???? I've heard yay and nay and have no professional opinion. Personally, I have no problems recieving a call, sms, etc... while connected to GPRS.
As far as power consumption, I would assume yes, it sucks up power. I have noticed about a 15% increase in power consumption using the web for an hour or so per day as well as automaticly checking email once every 45 minutes.
I also recently discovered a beautiful little prog that I cooked into my MDA I OS. PocketNav. It allows you to switch programs, close certain ones with only two "clicks", or all the progs at once, etc.... Check it out!!! It will be worth your time (I don't know where to get it other than stephan's kitchen).
Good luck!
gsm and sms should disable grps while it's using the band
but not cause problems
there is also the program PHM task manager
which is pretty much a copy of the task manager in windows 2k and xp so if people know and like that then it's a good program

He Dustoff,
Great stuff! Worked fine for me. Thanks.
Ronald
Dustoff,
Where is the Red dsiconnect button I am supposed to press and hold?
I am using WM2003 and after Iam connected, i havent been able to find any place where there is any disconnect option. in the connection bubble all i can see is that i am "connected" but there is nowhere for me to disconnect.
Can you please let me know where you find this disconnect option.
thanks
Red disconnect button
It is simply the red button of the telephone.
On another hand, if someone calls you exactly in the same moment when yours GPRS is fully active downloading something (a big picture, a long message, ...), you may appear as "unavailable"

Hi.
I have not tried the above software yet, but here is the problem I have...
I use Wi-Fi a lot at home and quite often keep the Wi-Fi on and use WiFiFoFum away from home. I have managed to set up my pay as you go GPRS connection. But whenever I'm away from a Wi-Fi network the GPRS connects and my applications then access the internet.
There needs to be an option of "not connecting gprs automatically when there is no Wi-Fi connection."
What I have had to do is change one of the setting for the gprs so it cant connect, and I have to change it back when I need it.
Switching from Wi-Fi to gprs can cost a lot if things connect without me knowing. It costs £3 for a months use of 1Mb.
Regards,
Ian Watson
creating a phantom connection, and "picking" it as default may be slightly quicker than changing the settings of you primary connection.
I think holding down the HANGUP/STOP button for 2-3 seconds is the fastest and easiest way.

I have found where I can stop it from connecting the GPRS if it cant get a wi-fi conncetion. Connections icon on the connections tab, then the advanced tab, then the select networks button - "programs that automaticall connect to the internet..........". I have changed this from gprs to my isp.

I found a lot of posts where people ask for auto disconnect. My problem is the other way round: When I connect with GPRS after some 5 minutes or so my QTEK S200 disconnects by itself. This might be caused by the cab file MP_autoDisconnect_EnableDRM_prophetUA(AKU2.0)_060112.cab which I found in enhanced ROM?
I don't want to hard reset to see the effect this cab not beeing installed. Any ideas to help???
I have the same problem... lets see if anyone knows how to enable GPRS for longer then only 6 minutes.
I have the same problem... lets see if anyone knows how to enable GPRS for longer then only 6 minutes.
it's because of your mobile operator. i've the same sh.t here. it keeps disconnecting after 5-10 minutes and the traffic rounds up. and i have to pay more... i've a hima, my friend's SE W800 - same crap, keeps disconnecting. i'm sick of GSM networks, they're getting old and do not meet modern speed and reliability requirements. so i'm afraid we'll just have to wait until WiMAX or something else comes to replace an old man. cheers
You might wanna try this from wiki here:
If you want your GPRS (or EDGE) connection to always be on, set the following:
HKLM\Comm\ConnMgr\Providers\{7C4B7A38-5FF7-4bc1-80F6-5DA7870BB1AA}\|gprs connection name|\AlwaysOn = 1 (DWORD decimal)
And to turn it off:
HKLM\Comm\ConnMgr\Providers\{7C4B7A38-5FF7-4bc1-80F6-5DA7870BB1AA}\|gprs connection name|\AlwaysOn = 0 (DWORD decimal)
Note that |gprs connection name| will depend on the name you've given your GPRS connection
I'm on tmobile web n walk, so its a pain to wait for gprs to reconnect everytime.... I've just started using this for about a day, but looks ok so far... try it... see if its the magic ur looking for

I don't think it's connected to the provider as I know enough people using the same provider where GPRS stays connected a long time. The only difference we have is the PPC. I will try jamichy's solution later this week when I will be back home. In the meantime Craic Dub - does it solve the problem on your side?

O.k. I couldn't wait and tested today. Now the connection seems to stay as long as you do not stop it.
But: It connects automatically to GPRS when you connect the phone to your provider. That's not really what I wanted. In other countries this will create extreme roaming costs.
Any other idea on how to stop this auto connect? Even using phonealarm's "do not start GPRS automatically" does not help, again it starts connecting when you dial in your Phone PIN.

Seems the Reg Hack is not a brilliant idea... I have setup my device to power off display after 2min... when i press power button to come out of standby, it freezes the device for abt 40 to 50 sec
Its worse when i get an incoming call, the screen is on but does not respond to touch or pressing green button...
So i changed registry back... and bingo, everythings ok again....
But now, i've found another way, a little freeware app that does all I want and more, and you get the option to choose connect gprs on boot or connect when needed... etc... take a look at:
http://www.gb-soft.cz/XDAII/product_gprs_tweak_wm5pe_en.htm
I'm using now, and seems ok

Sounds interesting. Still difficult for me to understand what it really does:
- What means "search GPRS [G] on start radio"
- What means "start [G] on start GPRS
- What means "Switch GRPS always On/Off hold till for following connection"
Can you tell me what it does non your side? Im a startting to hesitate trying to many things. I am still not convinced of WM5 - I installed GPS pgrs monitor (on QTEK CD...) which did not work together with phone alarm. And to deinstall was the ususal WM5 hassle, only using sktools and manual deletion of a file after another soft reser I was able to remove it again
Search GPRS ON start radio=gprs connects on startup
Start G on start GPRS=gprs connects when an application needs web connection, and stays connected
Switch GRPS always On/Off hold till for following connection=default settings, connect when needed, then disconnect
Havent had the phone freeze problem, and gprs connects on startup, and stays connected... which is fine for my tariff, tmobile web n walk unlimited gprs

Seems to work flawlessly so far on my S200. Thanks for your help Jamichy!!
The only thing I'am still missing is EDGE in Germany... :wink:
hi, i am having an odd problem after upgrading my rom to letes t-mobile rom and getting rid of customization(soft rest before customization) i am unable to turn off GPRS ( i have entered the GPRS settings manually). the only way to turn it off is to perform soft reset or turn on on the flight mode and then turn it off. when i tab on active GPRS conection there is "disconnect" option missing. is there any way to resolve this problem ?? and the turning off and on on flight mode for some reason dosnt respond really quickly and i have to do it a couple of times.
as to the ROM itslef seems to be OK..and without costumization wizard works really quick !
cheers, matt
Change it with this reg tweak
To disable gprs always being on:
HKLM\Comm\ConnMgr\Providers\{7C4B7A38-5FF7-4bc1-80F6-5DA7870BB1AA}\Connections\|gprs connection name|\AlwaysOn = 0 (DWORD decimal)
Note that |gprs connection name| will depend on the name you've given your GPRS connection
value = 1 for gprs always on
how do u DO this ?? do i need a piece of software or ??
cheers, matt
You need a registry editor and change the value - find attached.
Copy cab over to device and click on it through file explorer (do not open it on you pc)
If you are not up to doing that - pm me and I'll sort it for you.
i have recently updates my rom to get rid of the customization, and now i have gprs/edge on my fone, but i dont currently have a data serice on my fone, will i be charged if i conitnue usin it
From time to time, like if I go into an elevator or a parking garage, my 8525 will show 4 bars but will pop up a bubble that says that there are no active data connections present.
Short of going into the settings, disconnecting the current data connection, creating a new data connection, etc....is there a shortcut to getting it to initiate a new data connection?
Just going into IE and trying a search won't do it. It simply says to check network coverage.

There is probably more than one way to deal with this.
You could add the disconnect button to the pop up bubble that appears when you tap the connection icon in your task bar. With this facility you would just disconnect the connection and the for example if you do a search with PIE it will create a fresh connection. (saves you all the bother of going to connections to do it just tap the task bar icon). This feature can be added by the following registry tweak:
To add Disconnect button and a timer display showing how long GRPS is in use for the session:
HKLM\ControlPanel\Phone\Flags2 = 16 (DWORD decimal)
To disable both the Disconnect button and the timer:
HKLM\ControlPanel\Phone\Flags2 = 0 (DWORD decimal)
To have only Disconnect button:
HKLM\ControlPanel\Phone\Flags2 = 8 (DWORD decimal)
OR
using HTweakC which gas an option to do the change for you:
http://www.fit4cat.de/thread.php?threadid=263
OR
Press and hold the red phone key for two seconds that will disconnect the data connection, ready to initiate a new one.
OR
Might I suggest Danielherrero's band switcher that lets you turn on and off any radio with relative ease. Though this may be more than you need really.
I use the disconnect button and then any new data connection is started afresh.

I'd like my phone to use the data connection to download weather info etc., but I'd also like it to turn it off when idle to save power. Is there an app to do this?
thanks
Click on the 3G icon on the top bar, then when the notification screen opens click on the 3G icon again, that opens the Comm Mgr screen, turn off the data connection.
OR, are you wanting an app that will do it automatically after XX min?
It should automatically disconnect after usage. I find my data connection active for like 23 hours and such. Big battery hog when it isn't even being used.
On my Fuze, there was a registry edit which would set your END key to disconnect a data connection while on the homescreen in the default position. Worked really well except it doesn't work on my new AT&T Pure for some reason.
A single tap would work exactly like the END key currently does. Pretty nice.
Code:
[HKEY_LOCAL_MACHINE\ControlPanel\Phone]
"Flags2"=dword:0000000A
Flags2: "Enables a disconnect button for GPRS connections to appear in the connectivity list. Also enables End key to disconnect GPRS."
[EDIT]
Actually it may still work. I just found that further down in my app.reg of my Custom folder, I had it set again, to 16.
[EDIT2]
Yup. Changing the value to A (A=10) works like a champ. It doesn't affect any normal End key functions either.
Alternatively, if you have TD2 Tools (which you should, great program), then under the Power tab, there is an option to 'Auto D/C Data Connection'. At least there is in 2a, v 2.0.3552.42948.
Yes, I want an app to disconnect the data connection after a few mins/secs. It should save power.
I will try the TD2 tools, I already had it but never thought about looking if it had this option built in.
Thanks to you all!
EDIT: It worked, it disconnects after a few minutes now. Does anybody know how to disable wake device when receiving SMS? The option is turned off, but still the device wakes itself.

Hi
The data connection being on does not drain the battery. You have a network connection to the cell all the time otherwise you wouldn't receive phone calls, the data connection symbol just means your phone also has an IP address, that doesn't take any power.
If anything the connection remaining on saves power as each time you need a connection one doesn't have be created. Creating a connection uses more CPU cycles and radio power talking to the cell to open a network connection and then more to drop it.
The network operators also want the connection to remain on as it is less load on their networks than having them continually created then dropped.
More info here: http://blogs.msdn.com/windowsmobile/archive/2006/07/14/666203.aspx

you just need to modify these two entries (was written here many times)
Hkey_local_machine\Comm\ConnMgr\Planner\Settings
1. Change in CacheTime DWORD Data to 15 (Base is Dec value)
2. Change in SuspendResume the value to GPRS_bye_if_device_off
Make a soft reset.
The data connection should turn off after 15 sec if idle. It should also turn
off after you press the red key, or turn off the screen.
Try it.
Both solutions (reg mod and TD2 Tools) work most of the time, they are in fact the same. However I noticed 2 curious behaviours in which the timeout is not respected.
1) When I update weather via DataConnection, it does not autodisconnect after the preset time...it will when device goes in standby mode.
2) Data Connection stays on until Opera is open (even if not used).Once closed, timeout starts, and it's not that bad after all.
Can anyone confirm?
I used the TD2 tools, and i'm not experiencing these issues.

This is good advice. Has anyone every experienced more battery drain if the the data connection is "left open"?
In any case, even if you "disconnect" data every time, if an app wants to access the internet, doesn't wm reconnect automatically again? (unless you use modaco "nodata" app or similar to inhibit it)
Didn't notice more battery drain with a data connection left open and you're right: if an app needs connection then it will automatically be opened. In my case I want auto disconnect because, even though I have 400 monthly prepaid connection hours, which is enormous for a phone, it annoys me to waste them while topaz is in my pocket.
Wow, thaks for the great tip Phil!
I have a prepaid 150MB limit, so it shouldn't bother me leaving it on. The 400 monthly hours sualc mentioned is indeed more of a problem.

The problem mentioned above, about auto-disconnecting when programs are being used... this is why I program my reg edit to manual disconnect.
@BumAround: Set the value to "0000000A" (which is hex). "16" was my default value, which was also Hex.
This will do 2 things. It creates a "Disconnect" button from the PopUp Connection window and also allows the END key to disconnect only while at the Today screen in it's default position.
For example, if you are browsing Opera and press the END key... it will only take you back to the Today screen and won't touch your data connection. If your at the default position (the Clock tab on both Manila and Titanium), pressing END again will stop the data transmission.
It is a very good solution to the OP's problem by allowing you to disconnect the data connection easily, at will, and without the need for extra programs.

Not sure about this... and forgive me if I shouldn't be commenting because I'm referencing a cdma HTC touch pro 2, but I think this aspect is common.
My understanding is that the arrows up in the status bar should show white when a data connection is active and transferring data, but should turn gray when the connection is connected but not actively transmitting data. On my TP2, the data connection always shows the connection active and transmitting (the arrows stay white and never turn gray). I'm thinking if this is happening, one must surely be eating battery that isn't necessary.
On a cdma phone, the GPRS registry setting that is mentioned in this thread won't work because, although it will make the data connection automatically disconnect after an active data session, and you can change how long that time is with the CacheTime registry setting, unfortunately, on my HTC touch pro 2 Sprint cdma phone, you can't answer incoming calls when a data connection is active using these settings. I have to change the GPRS setting to #777 instead to be able to answer incoming calls when a data connection is active.... and with the #777 registry setting, I then loose the automatic time out and turning off of the data connection, so it stays on and showing active unless I turn it off manually and even then it comes on by it's self so often it's not even worth turning it off manually.
If any of you tech wizards can find a way for me to both be able to answer incoming calls when the is an active data connection, and also have the data connection time out and turn off automatically when not being used, I'd love to see it, because it sure seems to me I use more battery when I'm not turning off my data connection a lot manually, but it gets old always having to turn it off too!
