CPU changing speed - AT&T Samsung Galaxy S II Skyrocket SGH-I727

you only under clock for battery right? i assume you over clock at home right? or is it bad to change it often? i wish there app that change cpu depending on location. is this possible?

Your CPU speed actually changes on its own rather often based on the load that it's taking on. For example, if your phone is just idling, the load on the CPU is close to nothing, so it's going to clock itself down to lower frequencies to save not only battery life, but itself from wearing out. Now say you're playing a game or watching a movie or something, it's going to do what it can to clock itself up to speeds to process whatever it's doing the best it can. Unless you have a STRICT clocking profile set up (say, min 1728, max 1728, performance), your clock is going to go up and down quite often. Download CPU Spy from the market and you'll see pretty well what I'm talking about.
Hope I was able to help!

I could not really see a situation where that would be ultimately useful, but yes download CPU Spy as the poser above me said and have a look at after a day's data gathering.

you should only have one cpu over clocking right.

correct only one. Personally I use fauxclock with faux's kernal

Droid Overclock [Pretty Sweet App]

Droid Overclock is an app I ran across on the Market today with all sorts of nice features.
It may have been out for awile, I just didnt see it.
It costs $1.50. Very Nice App
Looks like it does alot more then setcpu
Oh yeah, I bought this app when I had my d2. Wasn't sure if it supported the incredible though and I just use the built in overclocking in CM.
Its a sweet app though and jrummy did a nice job with the interface.

Makes your processor operate at a faster speed, speeding up your phone. It kills your battery faster though.

Actually (What effects screen brightness and OC CPU have on battery) speeding up your cpu doesn't effect that battery as much as you think its very minimal. So overclock all you want
Does it harm your phone in any way?
Sent from my SGH-T959V using XDA App
This actually looks a lot better than SetCPU. I like it.
If you overclock too high, to a incompatible setting, the phone will just go into a loop mode. The setting won't be stable.. it errors itself and can't correct it. So you need to scale it back down. Sorry if I don't know all the terms and such.. dinc's are fast just to begin with. I oc'd so I could try and get better benchmark scores. It worked and the phone was stable to where i could use it all the time problem free. I managed to get scores I could be.. once that happened I stopped clocking up, and started scaling back. Undervolting the system with a different kernel / governer setting will yield you the best battery life..

Keeping your phone overclocked at 1728 MHz? Good or bad

I have my minimum aand maximum CPU frequency set at 1728. Good or bad? What is your set at?

Hi,
Does that mean it's running at 1.7 ghz even when it's asleep?
I would think that was like driving your car with the gas on full,even when it's parked up.
What do you think it will ultimately do to your phone?
Yeah I think that's what it means. Lol idk. But I don't know what it might do like you said it might be like driving your car fast non stop that might harm my phone I don't really know.

Hi,
Why don't you set the minimum to 386 and the maximum to 1.7.
That way, at least, it won't be permanently on.
See how it goes for a few days.
Not all phones will run at that speed.
If it becomes unstable,put it back to 1.5
Bad if you want long battery life, good if you want fast performance each time you use the phone.

It's massive overkill.
You won't need that kind of CPU power except for a few things. An on demand governor will give you that power when you need it and save it when you don't.

Voltage adjustment is not really necessary, unless you are increasing voltages for overclocking.

Voltage adjustment is necessary when UVing so you can save battery duh??? lol
Even when overclocking.

Uhh, no. I suggest you read up on the findings/observations documented by multiple kernel developers and bedalus's kernel testing posted here. UV has no effect on power consumption.

Well I tested it on my friends nexus s 4g and my epic 4g and with a lot of UVing. Lemme further explain.
Okay when you UV it just uses less amount of voltage on that frequency so in essence you save battery because not as much voltage is being used. Now however if you UV by a lot like -100mV and higher the phone will lagg a bit. If you overvolt your pushing more voltage to the phone which is more power being used.
I just tested my phone freqs. Used were 100,200,400,600,800,1000 And all were UVed by -100mV and playing games and using lower freqs it will lagg. When I didn't UV at all it never lagged.
Not to mention BTW I was @ 88% before and it only took me 2 mins to post this and now I'm at 86% with no UV at all. And last post before this I took me same time with UVed I went from 95% to 95% lol.

Not according to my testing.

Well I can say every phone is a tad bit diff. But for whatever reason no matter who's phone when I UV if the phone handles it it. It saves me battery I want you to test this and see.
Run whatever scheduler and say performance run 100 MHz by -200mV like and 200 Mhz by -150mV and so forth. Play GtA 3 and watch when UVed it laggs and when Not it laggs stillbut not as bad. I mean hell even 1.5GHz no UV I still lagg haha

How do I enable cpu1?

I have a Skyrocket phone, running Sky ICS... and I've been trying to find out why cpu1 is off most of the time.
/sys/devices/system/cpu/cpu1/cpuidle/state0/time = 534677824
/sys/devices/system/cpu/cpu1/cpuidle/state1/time = 0
When I echo 1 > /sys/devices/system/cpu/cpu1/online
And then cat the file back, the setting is zero.
How do I set it online? Is it possible?
Thanks in advance,
I flashed the a different kernel with Sky-ics and I use CPU tuner it shows I'm running both cpu's. I believe the ics update was to enable both cpu's anyway but then again I'm new to this and still in the process of learning haha give cpu tuner a shot hope any of this was helpful.

CPU...
Most of the time you probably don't want the other CPU running. 1 CPU is more than enough for most apps and tasks. I know Instigators Kernel basically shuts down one of the CPU's unless you need it. I am sure if you updated to the kernel in seans thread it also mods the CPU Governor. ICS by default has both CPU's going all the time.
So having 1 of the CPU's off is one of the benefits of modding. It saves precious battery. If you get a program such as CPU Spy, you should hover around 192 mhz when using the phone for light tasks. 1200+ is more graphic intense. If you start doing video and games, CPU #2 kicks in to help...
To change this setting on most roms, goto system settings>Performance>Processor and change the Governor type to one that suits your needs. I use Instigators Kernel with the Badass Script and I get AWESOME battery life and sit on 192 mhz most of the time and notice NO DIFFERENCE in the speed of the phone...
Hope that helps... if so, give me a Thanks...
If you punch CPU 1 in its kiniggits it will fire right up

[Q] Safe Overclock

Hi yes im new but not quite a noob :cyclops:
There with that out of the way my overclock settings are 1200mhz min 1600mhz max
so far running great with the HellyBean rom
But how would this effect my phone long term if any and I would like to be able to moniter my cpu temp like I do on my pc
but the thread http://forum.xda-developers.com/showthread.php?t=1140371&highlight=cpu+temp
has some good apps but they don't say cpu temp just the battery temp unless there interlinked some how
Thanks for looking
No temp sensor on the infuse except for battery.
1200 is really high for a minimum... This should be 100. For performance set governor to ondemand.. This will Max the cpufreq on any load. When idle, freq will drop and save battery and cool phone.
Running for extended periods at 1600 your phone will get very warm to the touch.. Combo of cpu and screen... If plugged into charger that will add more heat.
Battery Monitor Widget is a good app for tracking battery temp and related stats over time.

Thanks ya I figured it was a bit high
Do 100 min and 1400 max
And governor to on demand
Also i set up profiles with set cpu so when screen is off the maximum goes down to 400mhz.then screen on profile the max is 1400.it saves battery

How do you set up profiles?
Sent from my SGH-I997 using xda app-developers app
Use a CPU manager like SetCPU ($). Voltage Control or Antutu CPU Mgr may also have profiles.. Not sure -it's been a while since I used either.
Sent from my SAMSUNG-SGH-I997 using xda premium
The only ones I found so far that have profiles are pay for but once I get one I think its going to be either ROM manager or antutu
