I have Battery Status 1.04 beta on my 8125..I set the CPU Scaler to underclock to 112mhz when idle (original is 195mhz). It seems to be doing that, but idle battery life so far doesn't look any better, in fact maybe worse. Is CPUScaler not meant to be used like that?

it does / will / or is supposed to help by slowing down your processor when it isn't actively being used. But 112 seems really low to me. I've heard that some people find their phones won't wake back up when it drops too low (I think 123Mhz is what I've read people use but lower than that caused problems). Personally I set mine to 143 for the min.
If you are running WM6, there just seems to be more power drain. Also depends on what radio you are running (some are better than others) and if you leave WiFI and/or bluetooth turned on all the time.
Also I've read that some apps will cause more power draw due to them running. With BatteryStatus when your phone is idle, does the CPU % go down to 1 - 3%? If so, you should be ok. But if it stays higher, then something is running and that adds to more power draw.
There is also a thread in the Wizard WM6 forum on people finding that playing with the extended rom seems to impact on power draw if you've done a hard reset or similar (they are finding that by going back to an official rom like TMo 2.26 and then reinstalling the custom rom that doesn't have an extended rom the power draw seems to go away).
Hope some of that helps...
Haven't had any missed calls AFAIK, been running it like this for a couple days now. My ROM is Faria's AKU 3.3, which is pretty good might I add.
Idle CPU utilization stays at 1%
The extended ROM theory is interesting, maybe thats whats doing it. My last ROM didn't have anything like that and seemd to have better idle battery life.
If the phone is at idle, what does it matter where it's clocked? When the phone is active, the battery will be drained regardless of clock speed. I have my 8125 set at 192MHz, nd have no problem re-charging the battery.
hey guys! which backlight settings do you use for optimal battery life? 40% brightness? or do you just use the automatic version?
I use 50% when watching films, 30% general use and 20% to 10% around the house in the evening! Bright screen on this beast - no need to use the auto settings as this seems to give me the equivalent of 20-30% "overbrightness".
I use a program called "Backlight control" by Ulrik Jensen, and I have it as a short cut on the today screen to quickly alter the settings...
My HD2 is running at around 20% CPU usage when idle according to BATTClock. This is even after a hard reset with just Batclock installed, no radios on, and HTC Sense shutdown (just on old Windows today screen). Is this normal? No wonder the battery life is so short.
My Touch Pro generally shows 1-2% CPU usage when idle even with phone and push email on.
Task manager doesn't show any processes or application using that amount of CPU. Is it just Battclock that is wrong or is something else going on? I have turned off all location services.

Interesting fact. Needs more research though...
I've tried everything I can think of, including switching off automatic backlight sensing, location settings, etc. and Battclock still shows around 20% with nothing running. Any ideas for a more sophisticated tool to monitor the CPU? Does anyone else with Battclock installed notice this?
And if battclokck use 20% of cpu ?

BattClock itself does use almost no CPU. But HD2 has the ability to lower the CPU speed. I use a Microsoft API to get the idle percentage. Apparently this Microsoft API does not correct for the CPU frequence change?
You can check with a Task Manager, which process consume how much CPU, like FdcSoft TaskMgr. Then you can also check if BattClock is wrong.
I am planning to add another method for measuring the CPU spent, so for now you can better first check if BattClock is right or not. I have a Touch Diamond and there the CPU percentage is reported the same as the Task Manager.
WEll, mine is 56% atm and i have no idea why.
the only reason i can think of is g-alarm and messenger live
On a device that changes the CPU clock to meet demands, CPU percentage means nothing if you don't have a way to know at the same time what the current clock is.
And yes, Battclock itself might not use a lot of CPU, but it seems its way to draw itself on top of the menu bar is not very efficient. A bit flaky, the redraws are not clean, and I wouldn't be surprised if the system calls it uses do use a lot of CPU.

Mmmm....I wonder what you're basing your comments on. Are you saying that ZuinigeRijder is lying?

The Qualcomm CPU, the one the HD2 has, reduces it's clock speed when it is not needed to run at full capacity to save battery life.
i.e. If the CPU is running at 1Ghz, and a program is using 1%, it will drop the clock speed (due to lack of activity). Say it then drops to 100Mhz, it will then be running at 10% of the CPU clock speed.
A simple way to check wether battclock influences the readings somehow (which I don't really believe) would be to turn it off and check, as zuinigerijder said, with fdcsoft advanced taskmanager.
BTW I also get ~20% usage when idle, in some manila interfaces I get to lowest values of 7%, but then back to ~15% and then again ~20%
No way to know the current clock of the cpu?

I think you've hit the nail on the head. When I start a new program the CPU% drops briefly to 1-2% before climbing again. I guess this is the device ramping the processor back up before launching the program, hence dropping idle usage from 10-20% of say 100Mhzto 1-2% of 1000MHz.

Extract ,power settings, from omnia 2,is it possible?Put it on htc hd2,in cab format,regulate the speed on the CPU and save the battery life?Anyone?
i'm playing with different rom
at the moment i have discarded all the rom that give me problem (even if some of theme was very goood!!)
now i have installed on SD -=MDJ FroYo HD v.4.6=- with different kernel.
very good...responsive..everything works (except automatic brigtness features)
my question is?
how can i understand if the power consumption is too much?
of course i will keep installed for few days and see if is compatible with my usage but i would like to know some "avarage" values in order to understand immediatly where i am.
Install CurrentWidget.
Set it to log the MA once every 10 minutes.
Normal usage varies anymore from 100 to 350ma, depending on what you're doing. I believe it might be higher if you're using the camera.
Standby should be as low as 1 ma to 5ma with wifi and bluetooth turned off.
arghh in stand by it almost impossible to have less then 5mA...im using Battery Monitor app and it's normally 5mA stable with very minor increase.
i will see on the real use if it's work or not.
First - let me state - and it is true - that I used the search function.
I read pages and pages of advices to lower battery consumption on my HD2 Android... without success...
First I used an SD ROM. I read that a NAND would improve battery life. So this is what I did.
I am also using SetCPU with a profile when battery <30% and another one when screen is off to LOWER the CPU speed. In normal use, I set CPU speed at 768MHz trying to lower power consumption...
I use a task killer to free memory and prevent silly programs to drain my battery off...
I use Juice Defender to control wifi, data, etc...
And with all of this in place, my "Current widget" shows a consumption of 180mA with screen on doing nothing, up to 350-400-500!!! mA when acutally using the phone wifi+sync...
In the forum I read consumption like 3 mA - 9 mA!!! This is FAAAAAR Way lower than what I ever had with different builds...
So this is an help scream to everybody: what is your battery drain, and why mine is sooo High???
Hint: I am also a fan of LCD Density changer, with setting at 165... can this have an influence on battery drain??? I reverted to the original 240, doesn't seem to have any influence...
Thanks for your help,
Looki
My drain is 3-9 ma in STANDBY ONLY now and again slightly more but mainly the values stated. And my screen on between 120+160ma. Turn off auto brightness if you have it on, and set it at the lowest your comfortable with (display is big batt drainer) I DONT use taskillers as they do more harm than good. I use NO undervolting and only the default settings with my rom. I have low lcd density setting 167 i think. Lcd density has no effect on your battery drain!
Found this here. http://forum.xda-developers.com/showpost.php?p=13151738&postcount=11296 Might be of some use to you? (from hyperdroid gbx thread)
Whats youre rom?
And do u use ext partition on sd?
I dont even use SetCpu anymore. Only taskkiller.
Auto-brightness is on
Auto sync is off.
Im using UD 3.3 nand from crawlingcity
Stansby is 3 -6 ma
Using round 160 to 250.

How long does your battery last from 100% to self shut down? As for Current Widget, keep in mind that when people say "Standby", its generally referring to the screen being off. Set current widget to update every 30 seconds, and turn the screen of for 40 seconds. Then quickly turn the screen on, unlock, and check what it is reading then.
If its still high, try "Force Stop" applications in the Settings > Applications menu one by one, i've had to do this more than once to locate problem apps that were destroying my battery in standby mode.
I'm knew to Android, let me share you my idea.
I use UD3.3
I removed google stuff
gmail, search, etc
No auto sync
Location off
Always kill market when screen off.
I use beautiful widget for weather manual refresh.
I use battery widget
Auto level for screen
sometimes WIFI on
2g Only
2 or 3 calls,total of 3 to 4 min a day
My battery stay 48 hrs in STBY mode.
I think the most draining factor is
1) google stuff they are battery hog.
2) screen
3) bad written programs (every time they check connection to
internet or looping for doing something, looping will make
CPU in high frequency).
4) bad device driver such as BT which is known as 60ma
drain. it is not the hardware but it is the software doing
the drain.
thanks

Bt drain has been fixed, wil now get you 6-15 ma.
Google stuff aint bad, just set update frequentcy to manual.
(Helps with alot of other programms that require internet.)
