Please record backup values. For a comprehensive backup process please see my last post on page 2 of this discussion.

Dear G810 users; its about time we enjoy our winmo 6.5 without having to worry for missed calls and other problems due to dropped signals; I have attached a small utility which will fix this issue for you.

Instructions:
1. Download the attached .cab file and copy it to your storage card.
2. Install the program in the device memory.
3. Execute battery guard from your programs list.
4. Click th battery shaped like icon (Look in the bottom; second from right).
5. Slide to unattended, then click add (+) icon.
6. Look for; acm1, acm2, Ril and upt1; add these three one by one.
7. Now set for full power state for these options.
8. You may want to do a soft reset but not required though.

By the way do make a backup of your current settings just in case. Do this when propmted before changes are made.

You're done; enjoy this fix. Cool

Please feel free to ask any questions.

.Net Compact frame work is required, v3.5 available from MS

The utility requires .net compact framework, .net compact version 3.5 from microsoft can be downloaded:

Enjoy Very Happy

If you are having troubles with it, and it does not seem to work, then try adding only the IRL to similar phone states (Unattended, User idle, suspended etc).
_____________________________________________________________
This just discovered: The same can be done just by editing the registry; under:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\State

All options can be manipulated, key codes woud describe stance of each variable. Please see Tsuioku's post below to MSDN to understand power states and possible registry entries.

If any thing goes crazy just use the backupfile (PLEASE RENAME EXTENSION OF FILE TO .BCK) supplied here to use with battery guard to restore your default settings. Please keep me posted if things are giong well.

If anybody plans on trying this out, can you backup your current settings PRIOR to editing anything and upload your bck file?

It will be useful to have something to fall back on in case something is tweaked incorrectly.

It seemed to work at first but doesn't seem to be working anymore.
EDIT: Adding RIL to the Suspend page and setting it to Power Save seems to solve it so far while reducing battery drain (guessing...)

Before everyone starts tweaking their Registry, the value is NOT Boolean
The DWORD/Decimal values are as follows:

0 - Full On (Power On)
1 - Low On (Power Save)
2 - Standby
3 - Sleep (Suspend)
4 - Off (Power Off)
[from MSDN: Device Power States]

I wouldn't recommend adding the values to all the power states as it my cause unnecessary power drain.

To the OP: Do you happen to know what UPT is?

RIL = Radio Interface Layer hence that is why I chose to change only that.
ACM = Audio Compression Manager but I haven't encountered any Audio issues at the moment so I haven't added it yet.

For those that have started playing with the program, you will notice 9 Power Templates, seven of which are the Windows Mobile System Power States.
After reading the descriptions, the Suspend and UserIdle seemed to be the main culprits

After a day of testing, Adding RIL set to "Low On" on the Suspend State seems to be working well. I'll see how Standby works so that hopefully I can extend battery life. There is sometimes a delay of one ring which may have been caused by not adding ACM. Maybe I'll prolly test that at a later time.

If everyone has any other findings, please share =)

PS. More info on BatteryGuard can be found from the developer's website or his XDA-Dev thread

Tsuioku's link to msdn is very informative. Based on MSDN, i experimented with my registry even further. I uninstalled the utility and manually abolished the entries regarding unattended, suspend and idle states from the device regustry; so far no problems and battery is functioning as normal. It is advised to all other users to abstain from tweaking the registry for now. I shall monitor my device for seven days and post my findings. Meanwhile you can play with the utility to enhace battery and IRL efficiency and use the backup if things go otherwise.

Just found a table of State Transition criteria which may come in handy.
Would have preferred a diagram but gotta make do with what's available.

Power States

On another note, my screen wouldn't turn off from all the tweaking I've been doing so I just did a Hard reset and noticed that upt1 is not a default key!

More useful Info
It appears {98C5250D-C29A-4985-AE5F-AFE5367E5006} controls your wireless power setting (ie keep BT, 3G etc on while suspended).
Yet to find out what the {EB91C7C9-8BF6-4a2d-9AB8-69724EED97D1} key does though.

Anybody that installed Battery Guard care to post the list of subdevices? Also, is ACM1 GSM6.1 or G.711?

Trying to troubleshoot an issue rite now where my Notification LED starts flashing but the ringtone doesn't kick in til 5sec later.
While this may sound trivial, my provider, Rogers (aka ROBBERS) has it fixed that VM kicks in after 20s!

Don't know if it's a software conflict but I have been getting a bizarre bug after installing Battery Guard on my G810 where if I tweak too much, my screen just won't turn off even after restoring a previous working bck.... even soft resets and power off freezes!
Had to do a hard reset and trying to avoid installing Battery Guard again.

which wm6.5 rom is best compatible for uk phone?
which of them all have u tried and works fine,without problems?
please suggest a link because i am afraid to download and install.
thanks in advance

I tested all possible power modes at different levels.
1. All power states enabled; deleted suspended, unattended and user idle. Caused 100% more battery drain. No signal loss.
2. Partial changes to all, unattended, suspend and user idle. Battery drainage at 50%.
3. Changes to only the three variables in isolation. Suspend mode was found to be responsible for loss of signal.
4. Changed current power registry value from (3) to (2). No loss of signal so far.
I will wait a few days more before recommending a hard solution. Please do not try registry tweaks at this moment. I will post details of a guranteed solution very soon.
_______________________________________________________________

I shall not recommend upgrading to any of 6.5 ROMs coocked so far, please do not donate half wit people your money for something that is a mere patchwork of others work. If you already have 6.5 installed then keep reading.

Agreed... Power Level @ DWORD=2 (Standby) seems to be most power efficient.

Did you notice any of the following scenarios?
1. Sound initiates ~1 ring after notification LED flashes (adding wav1 seems to have solved it for me)
2. Delayed audio notification for text messages
3. Delayed response for incoming calls (~4rings) at some time interval ~15-30 minutes after screen has turned off

mirportege, would you be so kind to post a screenshots, illustrated the actions with Battery Guard, that you described in the first post?
Just to make sure that I'm not made a mistake in options in this software.
Thank you in advance.

I'll post the screen shots in a few days.

I found out that i can't find a "upt1" in the list - tested on few 6.5 builds/..

Posted: Tue Nov 24, 2009 7:06 am Post subject:

upt1 isn't necessary...

Keep posted for the latest test results.

Yet another discovery; after hard reseting my device I went back to tweak the registry. This time I only fiddled with flag values and not the power states and its working. I set my flag values in power states where ever applicable to that of screen off and viola it works. Again, dont try tweaking the registry at this time; I am glad to announce that I have begun work on a ROM for G810 so if you can contribute any suggestions I shall feel obliged. Once the ROM is developed I shall upload it on this forum. BTW some people who are asking for money for work that even isn't their own can kiss my S.
