Hi Guys,

I saw this in a foreign website. Not sure if this has been posted.

[HKEY_LOCAL_MACHINE\Comm\AsyncMac1\Parms]
"DisablePowerManagement"=dword:1
Change to
"DisablePowerManagement"=dword:0

[HKEY_LOCAL_MACHINE\Comm\Irsir1\Parms]
"DisablePowerManagement"=dword:1
Change to
"DisablePowerManagement"=dword:0

[HKEY_LOCAL_MACHINE\Comm\PPTP1\Parms]
"DisablePowerManagement"=dword:1
Change to
"DisablePowerManagement"=dword:0

[HKEY_LOCAL_MACHINE\Comm\L2TP1\Parms]
"DisablePowerManagement"=dword:1
Change to
"DisablePowerManagement"=dword:0

This will turn on power management for the above protocols. Logically, it should save us some power. The orginal poster is using D700 and he claims that there is a significant increment in his battery life and it is better than the activesync tweak.

I am using HP6828. Just pop in the settings today. Hopefully this will save us more battery life.

Cheers!

Once u enable it, does anything extra appear in your settings? The expected number of days perhaps?

Y would the manufacturers disable it in the first place I wonder?

Nothing appears after doing the tweak. The initial poster claims that there is an improvement of a day. But he is using GPS. So, for us, we might be get a better improvement than him.

I have also just pop in the settings, so I also don't know how significant are the improvement. But anyway, the settings does not affect my usage (bt, infra, activesync) at all.

Well, its difficult for me to answer your question. There are alot of tweaks to the registry which can improve our speed and such. But why does the manufacturer did not enable them? It is the same situation here, users found a way to save power as manufacturer did not enable these power management in the beginning.

looking at the services where you are enabling the power mgt, I don't think you can get much mileage as these are not the one that sucks up the battery.

well, i am not sure if its my mind or wat, but the battery life seems to have increase. I left my 6828 battery life of 82% last night and this morning it is about 75%. It used to drop to 65-69% if there are a few email received through gprs in the night. This morning there are 29 email received and the battery drop is only abt 7%.

By the way, this email program is a from my company. It allows receiving and sending of email in realtime which means when the email goes into our corporate exchange/lotus server, we will recieve it from our PDA/mobile phone instantly.

On my 6828, it can last up to 1 and a half day Max. But after applying the tweaks, there might be a chance to go up to 2 days or more.

Thanks Rivaldo. I haven't been moving around in the forum so pls forgive my ignorance in this.

I have applied the registry hack above, my battery is getting a bit better from 98-99% to 91% overnight.

I used to be 99% to 75%-81% overnight

But i did something else beside this registry hack only. hard reset, apply server hack and etc..

end of test

Final update.

My 6828 now lasts close to 3 days with GPRS connected 24hrs. It used to last less than 2 days.

This is a major improvement in battery saving. Cheers to the guru who found this and cheers to me for sharing this!

:)

btw, I think i should show u guys what i have installed just for you to understand why my batttery drains so fast.

1) spb pocket plus
2) spb diary
3) spb weather
4) resco explorer
5) wm5torage
6) sktools
7) WISBAR ADVANCE 2
8) Mapking
9) Handmap (GPRS location service, quite similar to GPS)
10) TCPMP
11) Real player
12) ilauncher
13) HandCalender
14) Ownerphoto
15) Opera
16) Visto Sync Manager (24 GPRS connected to send/recieve emails in realtime - 100% push email)
17) bus-guide
18) lots of game + movies on my miniSD

I agreed with ruffruff, this registry changes can improve your battery life. I have tested it and afetr use my 6828 for 2 days (minimum usage) it still has 50% battery left! not bad!

previously, i need to charge my battery everyday!!!

ruffruff,

Why do you installed both the SPB Pocket Plus & WA 2?
Isn't the two are similar in its fucntions?

does this work for dopod 838pro?

it should.

this works for all wm5 which have these keys

well, i like the looks of WA2
for spb pocket plus. i am planning to replace it with pocketbreeze

i used pocket plus because i am using its weather and diary.
anyway, quite sick of it already. now trying out sbsh products. i like its ilauncher, cos it has the bottom taskbar

hey, glad to see that u have the same feelings as me.
at least this prove that it is worth to be changed.

hi all,
Just bought the 6828..1st time user of ppc...Just wana ask u guys where do i change the register?

I got to say it work for my 6818 as well. My case:
Charged to full before going bed, unplug power it show 99%,
morning wake up at 95% (previously used to be 71%).
Night time 8pm battery still good at 60 - 70 % (previously
like 19% and below)

I wonder all this tweaks is meant for what use. I mean why does those developers set the value to 1 instead of 0. Will rivaldo the guru know about this? :)

glad to hear that.
I am also benfiting from this tweak.

Hope to hear more good news.

u need to use a registry program.
either phm regedit or resco reg edit that comes with its resco file explorer

sry but where to dl this program i google found the phm but it wasn't able to install into my atom exec don't know y....den the resco need to pay

you just google reg edit, looking for PHM register editor.

sry your post not helping much i guess... alrdy said i found the phm but when i install in it didn't appear in the atom exec....

warning to DOPOD 900 user, do not apply the setting else you will having problem connecting to WIFI as it will take forever to connect. just tested with my DOPOD 900.

I am a dopod 900 user here and i have apply the settings. I do not experience any problems in connecting to my wifi even i have apply the settings. I guess it may depend on the individual user's ppc. But I do experience a great improvement in my battery life. Nevertheless, apply the settings at your own risk...

Yes. I agreed with you.

But currently on my ipaq 6828, the changes to the battery life are pretty much impressive. :)

I have a same experince as you with this file: PHMRegEdit.msi. After installed you cannot find the application. Sorry I overlook your question. You download this regedit.Mrln_ARM.CAB from here: http://www.freewareppc.com/utilities/phmregistryeditor.shtml, Copy it into your PPC storage card, used file explorer to open it, Just stylus it. Your job finished. Hope you enjoy!

thanks thsalbert

After applying this tweak.

Amazingly, Only 9% drop in standby mode in 7 hours.
(Device LCD not ON during whole period. Running Programs list only shown ActiveSync and Wireless Manager, Bluetooth off).

wow, good for you.
you have better results than me.

Mine drop to 89% after a full charge last night before I went to bed. Abt 7 hrs too. No application as shown in "Memory" section. But I do have my corporate software running with GPRS on.

Monitored 1 hour of Music streamed to Bluetooth earpiece,
no call or sms during testing, discovered battery drain by
about 17%. Using PocketMusic only, no other active program.

Anyone got better result?

1 hour music - only drop 17%...

why are all of you getting better results than me ... :(

Hmmmz,

Tried this on last Thursday and i have been charging my phone almost everyother day. The batt seems to be kinda of died.

Battery drain, careful about installing Today screen related program.
Previously, battery drain from my HP6828 only 9% (7 hrs. standby),
after applying the tweaks shared by “ruffruff”.

This morning, surprised to find a drop of 35% (same period).
This is what happens; I install a trial program, POCKETfacelift,
later found not to my liking and uninstalled it. So even it is
removed, something else was altered and kept running in background.
Particularly program involved Today screen function. Correct me
if am wrong about this.

Therefore, before any software installation, a full backup is
compulsory, revert back when things didn’t work out or even
in this case, heavy drain to the battery. Otherwise, we get
ourselves confused further with next installation.

hi ruffruff,
Do not forget, you had a lot more programs running in background.
Mine only basic function, surely there is improvement in your case.

Hi,

i've tried but i don't seems to have the entry below(mark in red) in my Atom.
do i have to add it in manually?

hi coldman,

if its isn't there, it advisable not to add it in.

hi,

a side note: what programs do you guys use to check the programs running in the background?

Did not add any programs or removed any after the change.
Have the following running on the today screen:

1) Task
2) messages
3) SPB Plus

No other programs.

Hi ruffruff,

Did the poster mentioned what protocols are these? I'm curious to know what these protocols (AsyncMac, Irsir, L2TP and PPTP) are. Wondering why the power management is disabled for these protocols ...

i use sk tools to see what are the processes runnign in background.
i use oxio to free memory.

on my today screen. i have the following plugin
1) hand calendar
2) owner photo
3) spb pocket plus (integrated with diary, weather and time)
4) phm traylaunch (with card export active)
5) wizbar advance running
6) Visto Sync Manager (instant push email through gprs running background as services)

thats all on my today screen.
the rest of the programs, i don't want to list already ... too long.

nope...
he didnt mention any abt this.

from the looks of this protocols, they are more link to work connection.

i don't believe u are using vpn connection on your mobile device to connect to your company network and remote controling your server using terminal server client from the ipaq all the time right?

hey guys,

when I do a soft reset, the setting are back to normal. Is that normal? Is there any way I can set it permanently?

I am using Atom also but I can locate leh

I am using Atom but after I did a soft reset, the changes are still there

Are the registry tweaks to enable power management applicable to Palm Treo 750v? I don't seem to find the following that are talked about:

[HKEY_LOCAL_MACHINE\Comm\AsyncMac1\Parms]
"DisablePowerManagement"=dword:1
Change to
"DisablePowerManagement"=dword:0

[HKEY_LOCAL_MACHINE\Comm\Irsir1\Parms]
"DisablePowerManagement"=dword:1
Change to
"DisablePowerManagement"=dword:0

[HKEY_LOCAL_MACHINE\Comm\PPTP1\Parms]

[HKEY_LOCAL_MACHINE\Comm\L2TP1\Parms]

PLease help!

are these tweaks applicable to wm 2003 devices?

Hrm...don't know it its just my atom but my power management in my Atom is still the same. 100% @ 3am and thereafter at 7am in the morning left with 89%. I only have the following sottware:
1) Vicsoft Clear Temp
2) PHM Registry Editor
3) PocketMax Phonealarm
4) Scary Bear - Check Notification
5) Scary Bear - Clear Notify
6) PPCContactd Mgr
7) SM2005 Chinese Language Patch
8) Oxios Memory
9) Orbworks PokcetPC

there's a thread that talks abt the possibility of phonealarm draining the battery if u set the scroller on.

I am using phonealarm lite version thus there is no scroller function

Thanks.. this is my favorite hack for rw6828.. works perfectly.
