Hi
Does anyone use a MHz management/modification tool like XCPUScalar or PocketHackMaster? How does it work on the Magician? Which one do you suggest and what are the best settings and highest MHz you can have (stable naturally).
i'm using XCPUScalar v.2.87, but actually i use that for down the clock speed for saving more battery, it seem so stable from v.2.87 or later for O2 mini
Well doesnt the new xscale generation pxa 27x (like in the magician) do that automatically. From what I know they not only reduce the freq MHz (like XCPUScalar does) but also reduce the voltage of the CPU. Using XCPUScalar or similar tools may lower the MHz but not the voltage (they cant do that right now) so you will save more battery when not using that tools and rely on the internal speedstep of the CPU. For downclocking those tools are useless atm as internal processes do that way faster and better (because the lower the voltage too and save additional battery because of that). The only use is overclocking atm.
I've XCPUScalar on my S110 and only run it when I need more power and it will step up from 416Mhz to 520MHz and gives a nice speed boost (shortened batterly lifetime naturally). When I dont need that extra juice I leave XCPUScalar completely off because it cannot compete with the internal speedstep
You will alway burn more battery even with a clocked down CPU when you run XCPUScalar because the higher voltage those tools cannot control eats up the savings of lower MHz.
I just wanted to know what tool is best for overclocking. With XCPUScalar you can have 520MHz on the magician, lots of ppl say with PocketHackMaster you can have 600MHz stable.
By the way, you should intall 2.88 - way more stable on a magician.
Is it possible to download any software to give an estimate of how much battery life is leave in minutes etc ?
Also is there any software to allow you to underclock the device and improve the battery performance ?

spb pocket plus (or sbsh ilauncher I'm almost certain it's spb though) will display a battery icon with time left.
As for clocking, try this , but I don't think so yet
Try this one:
it also tryies to predict the remaining battery time.

I use xcpuscalar for overclocking, it displays % of cpu usage and allows you to enable OC depending on it. Works fine for me
Hi, is there an application for downclock the CPU of our PPC?
It's great to reduce the power consumption
HELP ME!!!
PS: In other case it's good also a software that sets different operation modes of PDA (performance, battery safe, ecc...)

Many thanks!!!
Hi guys,
If I remember correctly, in the previous WM versions there were options to change the speed of the CPU and that way to save the power and reduce battery consumption?
I am preparing for long, few days GPS assisted hikings and would like to minize the power comsuption of my HTC HD2.
Maybe there good apps for that too?
Thanks.
It already does that automatically.
Consumption of a GPS app like GPS Tuner with screen off is already very low, giving about 8hrs battery life (if you don't do anything else, of course).
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.
Cheers

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?
