Thanks for your reply. I installed the homebrew app "mode switcher" and IIRC there was a bootup service for this app.

I will try your hints during this weekend.

So let me get this straight before I install this.
I have the 800MHZ patch right now, I install this, it will put the MHz at 250 when I'm not using the phone, like when the screen is off?

In theory yes, but it scales frequently when checking email, IM idling, etc etc

[Timon]

So, I try it out.

I already got the message

** Message: serviceResponse Handling: 2, {"serviceName":"com.l337tech.cpuscaler","returnValue":false,"errorCode":-1,"errorText":"com.l337tech.cpuscaler is not running."}

And your scripts return following output

I haven't installed any cpu patch or overclocking patch before. Only the "Battery As Percent"-patch is installed.

Anybody having issues with random freezing using 800mhz and scaler 250->800? I had no issues running for 5 hours last night and when i got home I put it on my TS and at 4:48 am the OS froze. I am going to have to test running overnight without scaler.

[circuitjc]

Installed 720MHz kernal patch (to test and see if I go all the way to 800 or not) and your CPUScalerUber. I set it to 250 -> 720 and time_in_state shows it runs between 500 and 720 only. To be more clear only the numbers for 500000, 600000 and 720000 increase. All others do not move.

720MHzOS14.sh
CPUScalerUber App 1.1.1
CPUScalerUber 1.1.0 (service)

Thanks for your work. It is appreciated.

The service should be version 1.1.1 as well.

This is the link from the author's site to download the service listed with the Uber version of this app. Where do I get the 1.1.1 version of the service? Is it the same one as the non-Uber version?

i had issues freezeing with 125-->600mhz on the touchstone about once a week.

i have had no freezing with any of the 250mhz--> scalings. Been using 250-->800mhz.

my suggestion is start using 500-->800mhz. You cpu may not like those lower frequencies/voltages.

i checked the code and it is definately coded for 250-->720mhz. I bet if you let you phone settle down it will get down to 250mhz after it completes whatever background task it was probably doing. Let it run for a few hours in sleep mode then check the time_in_state table.

CPUScalerUber's service has not been ugraded to 1.1.1 yet. Its still 1.1.0. You have the correct version installed. ill let everyone know when 1.1.1 is ready (still doing research on the 720/800mhz kernel).

Everything works properly, though it appears that I have to set the scaling anytime I boot/reboot the phone. This is normal correct?

Perhaps a n00b question, but is there a way to start a particular scaling set on boot versus having to open the app and manually enable the scaling set?

Thanks

Developer stated that after a reboot you have to reset the scaling effect.

if you want to have scaling or a speed set on boot up then you will need a patch. Im not a fan of that so i wrote this application so i can choose what i want, when i want. I dont like being stuck at one setting.

when you reboot the phone sets itself back to defualt settings.

[edbbates11]

I as well like to be able to change the scale settings on the fly.

Ok, I'm using the 500-->800mhz. and it looks like it's working based on this. Already installed the 800 MHz patch a few days ago and hoping this will improve battery life.

cat /sys/devices/system/cpu/cpu0/cpufreq/stats/time_in_state

800000 626458
720000 5691
600000 0
550000 0
500000 15846
250000 0
125000 0

*** Should I expect in improvement in Battery Life and if so how much?

compared to running 800mhz constant speed all the time, youll see a decent improvement in battery life. They had tables comparing stock speed vs 800mhz speeds for battery drain and i think the hit is a few % per hour.

if you ran 250-->800mhz you may see even better battery life. If your really concerned about battery life i would run 250-->500mhz.

But as with any cpu speed you will drain the battery like crazy if the screen is on or if your 3g radio is on. At that point the cpu battery drain is a drop in the barrel.

I did test with 250-->800mhz for 5 hours with screen off and 3g/wifi off (airplane mode) and the phone used 1% battery. Pretty sick and eye opening on how little the cpu is actually using.

Thank you very much for the generous donation to a user who appears to want to remain anonymous.

Donations are the only thing that can keep developers like me in this thing. I have been giving the app away for free so if you enjoyed the app or found me helpful consider a donation. Any amount helps.

I've been very happy with the app so far and I have a suggestion for the next version release. Is there some way you can display the current status of the app when it is started? For instance, if the speed is stock and no scaling is on, have the button that currently says "Scale And Speed Off" say this. If the speed is set to 800 Mhz and scaling is set to 250Mhz, have the button say that. So whenever we start the app we can see what the current execution status is. With the current functionality, if the phone resets while on the ts overnight, I don't have any way of knowing that the speed and scaling have been reset unless I hook up to my computer to run a command from the Linux commandline. Thanks!

great idea. The new version (in its current state) has a "Stats" page that tells you everything about your cpu's current situation.

i like your idea of having some off that information on the front page when you first open the app. I will try and work that into the second iteration of the new app.

the new app is called CPUScalerUltimate. I will not go into anymore detail until i release it but i think anyone who uses this app will enjoy it a lot more than the original two.

thanks,
