Hi,
I use active sync with ms excange server over 3g/hdspa (trinity)! When I set schedule to "as item arrive" trinity is always connected via 3g, and I can't disconnect (except when I choose manual sync), does anyone knows what's about power consuption if is 3g always on but there is no activity (logically, I think that it will drain battery down!!??)
Regards!
According to MS the battery drain should be minimal. That is also my experience.

us people with hermes will tell you that 3G kills our batteries... especially us that use an always on connection (like pushmail, IM, etc)

Prob a silly question, but once the phone goes into standby (screen turns off), I take it the Wi-Fi connection is broken ?
Asking in case of push mails, because I do not get anything when in standby I take it that because Wi-Fi is also down.
Note - Just trying not to use GPRS, 3G when at home.
Another question does anyone know what the Wi-Fi power does, best battery or best performance other then what it says how is it doing that ?
Yep, Wifi is broken when your phone is in standby.
And Pushmail only works with GPRS and not with Wifi as far as I know.

thanks.
Jeegnesh,
To my amazement active sync works when your device is in standby and WLAN is enabled.
I use it now on the office and at home to receive my e-mail.
But to get it working properly you will have to disable "when new items arrive".
My device sync's every 5 minutes and notifies me when there is a new message.
Cheers,
Drifter
Did someone notice this when you Sync your device with an exchange server ?
If you leave the WLAN on and your device is in standby, your device will wake up to synchronise your device according the schedule of active sync via an AP.
When it does this your screen remains black and gives a notification when new mail arrives.
Battery consumption is low because WLAN will only be waken for the synchronisation and goes to sleep again after it.
I’ve tested this for the last week in the office were we have an AP an at home and it works perfectly.
The only disadvantage is when you’re out of the office it will give you a notification of every AP it picks up in your neighbourhood.
So you have to shut it down when you’re leaving home or the office.
This function was missing on my Wizard so I was still using my HP h6340 for this. But now I can leave this one at home.
Hopefully this function will stay after a few ROM upgrades.
Cheers,
Drifter
Re: the following quote in the amazingly comprehensive article on IMAP and the Pocket PC found here http://forum.xda-developers.com/viewtopic.php?t=62582&highlight=email+client
1.1.1 IDLE power consumption?
I’ve thoroughly tested whether FlexMail 2007’s / vgsmail's (the two IDLE-capable Pocket PC mailers (add-ons)) actively listening to the callbacks of IMAP server (while the Pocket PC Phone Edition device is suspended, that is, switched off) results in any kind of excess power consumption. No, they don't – you can safely keep them active while the phone is switched off; it won’t deplete your battery (and, of course, won't cause excess bandwidth usage - actually, as the IMAP IDLE protocol completely lacks "heartbeats", keeping up the connection takes less bandwidth than with Push Mail. Of course, the latter uses compressed data communication and, therefore, better under other circumstances - that is, when actively communicating.)

I cannot seem to get IDLE Mode working when my unit is sleeping, but only when it is on. Has anyone else been able to do this with FlexMail 2007 on a TyTN?
Thanks for the kind words
This would interest me too. Also, did you e-mail the WebIS folks?
I have a new AT&T Pure with an exchange email address set up to receive emails as they arrive. If the phone is not in standby mode the emails come in without a problem at the same time I receive them in Outlook. Once the phone is in standby mode (screen turns off) emails come in sporadically or not at all until I wake the phone up. If I just set it to dim and not turn screen off I am fine. Is anyone else having this issue?
I've found ActiveSync on my Touch Diamond2 very unreliable. It will work for a while but repllog.exe crashes at some point, usually overnight. Only fix is to restart the phone or manually kill the task - it's often doesn't respond to shutdown (indicating it's crashed) and has to be manually ended. Doing a sync immediately always works.
I'm hoping that they've fix this bug in WM 6.5...
Cheers, Rob.
This is a brand new phone with WM 6.5. Everything works finew when phone is not in standby. Once in standby emails don't come in when they should.

You mean by standby, not cable/activesync attached?
I'm still wondering about gmail push, I set everything up as said, but when I'm cabled to my work computer, I don't get gmail.
I have to disconnect and then get gmail push. **sigh**
Ahh, isn't that a setting on ActiveSync? Something about allowing internet connection when docked. I think when a WM is connected via ActiveSync, the internet connection goes through your PC which sometimes is blocked.

No, I unchecked that, same result, even after powering off/on. I think that option is misleading
some thoughts and my experience...
Do you expect emails to arrive over wifi, or gprs, The behavior is different by design.
As they arrive, in schedule settings for example only works as most people expected over gprs.( this is also called microsoft direct push) and can be toggled on/off in settings tab on most htc phones.
this also requires a constant open data connection over gprs. the phone will try to open it for you if you enable direct push option.
its also important that the carrier supports long http requests over grps for direct push to work correctly.(this is why gprs need to be open all the time)
if you deactivate the gprs-data connection, direct push will fail until it succeds a long http to the eas server again.(exchange active sync)
when i use direct push option over gprs, emails always arrive instantly (within a few sec.) to my phone regardless of standby or awake. 98% of the time anyway...
Now i have set mine to sync over wifi. however not pushed to my phone as it only works over gprs.i usually set schedule to 5 min.
if set direct push/as arrive over wifi the schedule seems to change depending on how often emails arrive. the polls seemes to be longer and longer apart if mailbox is idle. schedule a bit unclear...
i figured this out by setting a constant ping from pc to the phone and watched the response in standby mode.( wifi not set to always on even in standby) so i got response time out most of the time.
i noticed that after a certain time the phone began to respond to ping for a few seconds( active sync activated wifi in standby to check email according to my setting in schedule and then deactivated it).
if i had unread emails in my exchange mailbox they arrived in the phone as well.
i also read a paper where the direct push schedule where explained by microsoft. it is constructed that way to save as much bandwidh as possible,
i have based this on my observations only.
it would be nice if someone could find a technical paper explaining this further.
tests was done on htc p3600 and stock topaz. wm 6.1
i will do tests again on the 6.5 rom as they come online.
a
Phone is not docked nor am I connected with wifi. Just a GPRS connection. What I mean by standby is that I have the setting enabled to turn off screen after 1 minute.
I have no problem with push email from my exchange server. Remember Push email only works with cell data connection as pointed out. And if you establish ActiveSync connection with a desktop PC, it will be auto-disable and changed to polling instead regardless if you keep the data connection open or not.
I have never connected this phone to a PC.
exchange active sync and wifi
i previously had a TYTNii (Kaiser) which would exchange sync through my home and office wifi (over GPRS) when wifi was available and connected.... However on my Topaz i am unable to exchange sync through wifi when connected for some reason. it will only work through phone connection with wifi off. It appears there are additional connection settings with this WM6.1 device... (priority settings for one connection type over another) but im not sure how to set this up... Help on getting exchange sync working via wifi would be appreciated thanks..
I've set up my Gmail account using activesync (as item arrives) and all is well. However, I performed a few tests (sending emails to myself from other accounts) and noticed that the emails don't actually get to my phone immediately. They arrive immediately on the mail client on my PC but arrive about 10 minutes later on my HD2. Is this normal? If not, does the auto disconnect registry tweak I performed have anything to do with it. I'm guessing for mail to reach my phone as they arrive, some sort of constant connection is required with the google server. So does the auto disconnect tweak disrupt this connection? Also, is this constant connection drain the battery significantly quicker. I don't mind sacrificing a small amount of battery life for the push email feature, but if we're talking big drains then I might have to reconsider the sync frequencies.
OK, emails have started arriving exactly the same time on my phone as my PC mail client now. I'm guessing the auto disconnect doesn't affect anything then. It would be nice to know if its draining my battery quicker though when set to sync as item arrives.
Thanks in advance.
I was experimenting today and found the same issue. I'm not convinced that google sync works correctly just yet given that it is in beta.
I have gone back to non push mail.

So hows the pushmail going on with you ?
Does it receive mail instantly ? does it drain battery faster in that way ?
Autosync with gmail seems to be unstable. I usually get mail on my phone instantly, but sometimes it can take up to 15 minutes. It would probably be better to set the phone to check mail every fifth minute or so, but what about the battery?
Does the auto disconnect affect weather, twitter or facebook updates btw?
Genuine 'Push' email can't work if autodisconnect is enabled (and actually working!)
The message that a new item is available is 'pushed' to the device from the server, which requires an open data connection.
If the data connection is closed, the 'new item available' flags won't be received until either the next scheduled poll, or the next push 'heartbeat' connection from the device which reopens the data connection.

Weather will be OK as it polls the server on a regular basis which reopens the data connection. I'm not sure about Twitter or FB- maybe having the programs open maintains the data connection?

Everything works fine for now (push wise) but as NeilM mentioned, I don't think its compatible with autodisconnect. In notifications, it shows that the connection (T-mobile internet in my case) is still active. And when I hold the call end button and 'Terminate Data Connection' the connection is re-established again immediately.
To disable this constant connection, I've set it to download every 30 mins peak, and 60 mins off peak -
I've never used push email before but I'm guessing it creates a constant connection between the phone and the server.

Thats correct- the phone sends a 'heartbeat' signal every so often (depending on the Exchange server settings, but usually every 15 minutes) just to refresh it's current IP address setting on the server. In practice, the IP address will rarely change as long as the data connection is maintained.
In this way, the server always knows where to send items as they arrive, and the action of sending resets the 'heartbeat' counter. Likewise any item sent from the phone resets the 'heartbeat'
The data involved in the heartbeat process is around 4MB per month, which is similar to the amount used in the handshaking when polling at 30 minute intervals.
If you have auto-disconnect active, then the server won't be able to send new items, so they will only get sent when a new connection is established by the heartbeat process, or when a connection is forced by a send/receive operation.

Well, on my device, the auto disconnect never worked.
I set the values
HKLM\Comm\ConnMgr\Planner\Settings\CacheTime=60
HKLM\Comm\ConnMgr\Planner\Settings\VPNCacheTime=60
and set SuspendResume=""
And all the auto-updates are off (weather, stocks, etc)
and still - once I start a connection (Mostly if I do it for waether update, but sometimes even from SkyFire), it stays on, until I turn it off from the settings.
(Is there anything I missed in the settings to enable auto disconnect ?)
