[Touch Diamond, MDA Compact IV ROM Development] Belzebuth.:
I think it have something to see with Exchange...

I don't use it but I read on a french forum that there was some settings to modify...;)

Edit: It seems to have something with a corrupted connfiguration on the Exchange server (with Exchange2007)

I made a traduction for you with Google:

[RESOLVED] On battery consumption and exchange activesync

by gha Sunday, January 18 2009 - 20:30

I finally solved my problem of overconsumption with Activesync and Exchange Server!!

For memo from that ActiveSync was in the process list of Task Manager, even without synchronization of email, consumption in standby (screen off) ranged from 6 to 12% per hour.

The consolidation remained on standby as the case for no apparent reason and stuck at 60 or mah 120-140 (tested with Powerguard)

The assumption was that the exchange server side configuration was corrupt and that the connection was maintained after a synchronization. So I finally reset the configuration of my Exchange sync Diam's from outlook web access my Exchange server.

Since then, the standby consumption drops to be good, 20mah (excluding sync) even with activesync in the process list of Task Manager

As a result, consumer activesync set to:

- Synchronization of the arrival of a new message: approximately 2-3% per hour.

- Sync every 1 / 4 time: <1% per hour

To reset its connection-Diamond Exchange from Outlook Web Access

-------------------------------------------------- -----------------------------

- Connect to the Exchange server via Outlook Web Access

- Go to the Options menu / Mobile Devices

- Choose your PocketPC with the device ID for your Diamond

- Click on Remove the device from the list

- Launch ActiveSync from Diamond (diamond indicates that it's you must resynchronize after a change in the exchange server)

- Launch in sync data connection from Diam's (not connected to PC)

A priori, it resets something in the configuration "corrupt" of the exchange that makes the connections are cut at the end of each synchronization. Diam's therefore not unnecessarily consumes more battery to stay online.

For info, for me, this increase in consumption has been no apparent reason early November, when my host exchange (1and1) has migrated from version 2005 to 2007 exchange server.

I also Asynckiller, adjust the close connections to 15s with datas DiamondTweak, etc ... without result

Hoping that it will help some of you ...

Proposal to reset its connection to Exchange-Diamond from your PC

(untested, thank you for the return of those who try)

-------------------------------------------------- ----------------------

I believe that this approach can work, but I could not test it because I have the problem of the connection configuration "corrupt"

- On the PC, go to the manager of mobile device / mobile device settings

- Click on "more>>>" (bottom right)

- Click on "Ending the partnership Exchange Server"

- Reconfigure the Partnership Exchange Server

I tried it on 3 + ROMS Roma different radios consuming than I thought and it works just as well ... Now it is around 1-2% per hour with a large max sync every 15 minutes.

It was thus a problem of maintaining connection with continued exchange activesync sync (even if it displays no activity in the process list) in connection with a "corrupt" server-side Exchange.
