Is GPRS used up much power?

I keep my brand new XDA2 always connected GRPS to receive instant e-mail?
However, I found that my XDA2 using power very quickly.
In the past, when I used the XDA1, my GPRS plan is not that much so that I can keep it on-line all the time and the phone battery gone out reasonably.
Any thoughts?

Try a longer interval between checking the email. I originally had my XDA set to check every 15 minutes but I could see that it was sapping the battery strength. I dialed it back to once per hour (this is the longest interval you can choose) and I can go a few days at a time this way (depending on how much I use the XDA otherwise).

That means GPRS really consume too much power.
I will adjust setting to an hour.
Thanks a lot.

let me add small comment on this, it's not the 'alway on' that drain the battary, but any type of data traffic . it would be the same if you use CSD line. I'm not sure, but I noticed that phone calls do not consume that much ... maybe coz data traffic uses lot of buffering and errors handling.

WM6 UMTS/GPRS always on

Hi there,
My 3G connection stays on after a web browse or an email check process makes my device connect. I looked at "HKLM\Comm\ConnMgr\Providers\[GUID]\Connections\[Connection Name]" and to my surprise AlwaysOn flag was off. Can someone help me with this? I like the fact that my device connects to the Net automatically when there is need, however maintaining the connection kills the battery, I need a way to kill the connection somehow automatically (either after a period of inactivity or when the application requesting the connection ends).
Cheers,
Shafa

If it is maintaining Gprs on, there must be a program requesting it - do you have direct push enabled?
Also, having the connection constantly 'enabled' but not actually transferring data will have a negligible effect on the battery life so shouldnt matter.
If your battery life is significantly worse (as you have suggested), then you must be transferring data, so no matter what you do, unless you actually permanently disable the data connection so you cant use it at all, it will keep connecting to transfer whatever data it is transferring...
I hope that made sense

GPRS/UMTS
Hi,
Have you tried turning the Data Connection off by holding in the End Call Button for approx 3-5 seconds. This should terminate an active connection unless as mentioned above you have an app running that is requesting data.

Thanks guys,
1. the fact that only transferring data should drain my battery: makes sense; I will test more.
2. the fact that I can kill the connection manually: I could always do that from comm manager, needed it to drop automatically.
Cheers,

very basic battery question

I'm not new to the world of ppcs by any stretch of the imagination...but i have one question which has always puzzled me. How much strain does checking email every 5 minutes have on my battery? I have a gsm touch and can't seem to hold a charge for more than a day with very minimal usage. A typical day for me is 2 or 3 short phone calls and several texts..in addition to checking for new email every 5 minutes. Would I be correct in assuming that to check for email my touch is awakened from standby..thus causing the drain?

You are correct, but also consider that when it connects to check email it is using the radio to connect to the network. So essentially you are having the radio on almost ALL DAY. Similar to a voice call all day. Battery is then drained by the radio usage to talk to the network.

does the same apply to a push mail setup?

well...am i essentially doing the same thing by having GPRS always on? In other words, is this going to drain my battery at the same rate whether i'm checking for mail every 5 minutes or every hour?

No it is not the same for Push email. Push email wakes the device and delivers the mail when there is some. As opposed to the device connecting and querying for mail, the device gets woken (sp?) up and gets delivered the mail for Push. Push is a much more effective way of getting your mail... I forward all my mail to my hotmail account which then gets pushed to my device via Windows Live.
Regarding the always on GPRS... yes and no. Yes you are connected and draining the battery but just being on doesn't use as much as actually pulling or sending data. The difference is negligible and really irrelevant. I would say that you turn off GPRS all the time if you are trying to save on battery life.
Make sense?

You may want to install Battery Status and turn on the current drain option. While a bit of a catch 22, considering the screen has to be on for you to see what the drain is, thus causing a higher than idle drain. At least you can get an idea of what your device is draining and see if changing settings makes a difference.

The other suggestion is to consider changing ROMs. I have a GSM Touch and the factory ROM was really poor on battery life. I have been using the Blue Touch ROM version 2.10 (not the newest version) listed in the Elf upgrade section. I can now go more than one day without charging the battery, with push e-mail activated.

[Q] Get Results Faster option.

Hi guys. Somebody knows how much more battery this function drains when turned on?
Thanks

what function would that be?

It's in the save phone location... Don't kow if it really drains the battery...

If you have data connection on, or WIFI is connected to your device, this option will "locate" your phone on a regular basis, which means it basically turns on your GPS module, and runs associated services that will pinpoint your coordinates. Then it will send to to Microsoft. So, not a HUGE battery drain per say, but it does utilize more of your connection, and anything that is turned on can cut down on the battery juice.

Not quite. "Save my Location" is the one that turns on GPS and sends the location back to MS.
The "Get Results Faster" option, which the OP was asking about, is to select whether remote commands are sent via SMS or Push. I expect this 'may' have a higher battery drain because it will keep a data connection open if you're not already using it.

Moving from Windows Mobile to Android (HTC Sensation)....Data connection

Having decided against moving to Win Mobile 7 I got a Sensation a couple of weeks ago (from a HD2) and hence my first Android device.
All is going well apart from the data connection. On Win Mob 6.5 I had 5 business emails which the phone checked every 15-30 minutes. The phone would connect, check the emails and then disconnect. If I wanted to browse then when I opened the browser, it connected and disconnected when I closed it.
On the Sensation I seem only to have the option of data connection on or off. I have set the email to sync every 30 minutes but I have to have the data connection on all the time to let it do this. The battery drain is crippling.
I download Juice Defender Ultimate after reading another thread but after setting it up it only allows data for so many minutes in the hour and when I say that the browser should overide Juice it just says I have no connection.
I love Android but losing 75% of your battery in 6 hours because of business emails is not quite good enough.
So is there a way of getting the data connection to go on and off as required (both on demand and for scheduled automatic email syncs)?
And if not what Juice defender settings do I need to get it to do what I want?
Any help much appreciated.

I'm looking for an answer to this to, for the exact same reason. A "Data Connection Timeout" setting or something similar.

Switch to pushmail, saves you quite some data transfers and is more effective in the end. I have two hotmail addresses plus oen gmail on pushmail and I don't notice any more battery drain with data connection permanently on.

Settings>Mobile Networks>untick "Enable always-on mobile data.
This usually helps the battery drain a lot, especially if you don't have things that are always using data, like pandora and the like. If you have things set to specific intervals, then it should work like your WinMo devices and connect then disconnect as needed.
Admittedly the droid likes to be more automated than WinMo, and you have much less control than 6.5. (Never used Phone7, so I can't comment on that.) But, once you learn the tricks to using it (just like the tricks to 6.5) its just as powerful as WinMo was for the business geared user, as far as I can tell. The battery is something that takes some finessing as well, so keep working with it and keep learning. There are some pretty good guides available that can tell you steps to take, even a few here on XDA for the searching.
Good luck with your new droid device, it will become second nature in time. It took me a month to quit tapping the icons in the task bar. LOL.

Thanks for the replies
I think the fact that the HD2 and the Sensation both use Sense helps and therefore it has been fairly easy to get to grips with Android.
I have already unchecked the 'always on' option but I never seem to get any emails unless I open the email program up...even when its running in the background. Win Mobile 6.5 used to check without the email being open.
I have had another play with JD and seem to have sort of got what I want but sometimes the data connection won't wake up after the unlock screen without a data toggle on and off.
Is there any better email apps from the market?

Strange because when I do that I get a lot better battery life and my push Gmail arrives in 2-3 minutes instead of isntantly. also Google Talk won't stay connected with this setting. Other than that it seems to work really well for me doing exactly what you want.
