If you want to know exactly what is running on your device and how much of your precious system resources are being used, check out acbTaskMan. It's got most of the features of the desktop version of Task Manager, plus the ability to chart the CPU usage of single processes and the power consumption of your device.
Get the most from your device and reduce the drain on you battery. Here's the link:

You can also get the free battery meter acbPowerMeter from there.
Here are some screen caps

Also check Menneisyys' excellent review here
Does the powerchart in this app work for the HTC Wizard...more specifically the 8125?? I ask because several months ago i read a review stating it was not compatible.
Hi All,
I've seen a similar post regarding this issue but no answer as to why Xcpuscalar eats approx 40% constantly when the device is left idle. When first starting Xcpuscalar all appears to be ok. Then after about 30-60 seconds the cpu usage of Xcpuscalar shoots up to about 40% and stays there. You can see this either using the health meters page, the task bar CPU meter or any other tool such as task manager/Supertasks.
Never saw this issue on my Xda II. Does anyone else see this? Is it normal? I don't want to use this application if it is going to constantly eat my battery because of cpu usage it uses.
Cheers,
Richard.
What version of Xcpu are you using?
Try out the latest!
Underclock to improve battery life
This is purely in theory, but I was wondering if underclocking the cpu would allow for a little more battery time, like say setting it to 416mhz. Any thoughts anyone?
Try task manager and you will know which process eats cpu usage while you running xcpuscalar, may be xcpuscalar itself consumes cpu usage.
Then when you find which process uses more usage kill that process if it is not necessary or you can find why it eats lot of usage.
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?
Battery usage statistics keeps on warning me that Chrome has been using too much battery even when screen is off: is there a way to clear this stats?
How can I find out why my S7 Edge have to be changes 2- 3 times arbejde day and before only one ?
Disable runding background runding apps ?

Depends on your usage.
But if the battery drains faster, yes, you should check the apps running in the background.
Try to install a battery or data manager app and track your phone's usage. You could find something relevant.
Possibly a rogue app keeping your phone awake and stopping your cpu from going to sleep. I find Gsam battery monitor very good for monitoring app battery usage and cpu states, you can also enable more detailed reporting stats by using adb and the app guides you through how to do this.
If you goto settings then device maintenance, click battery and scroll down to always sleeping apps and add everything you don't need running in the background. Me adding all my apps made my battery last longer especially at night when its idle.
