SetCPU usage/benefits?

I was thinking about installing SetCPU but I have heard stories of it not working very well on the Captivate. Does anyone use this, and if so what kind of battery life improvement are you seeing? Post config settings too please!

Its working just fine. I have a live background so my battery usage isnt very great so long as the screen is on. I had some trouble with the system being slow to respond every time I turned the screen back on when I had "screen off" profile set to max 200 and min 100. then it dawned on me that it would always just underclock to 100 I set it to max 200 and min 200 when the screen is off and also started using launcher pro and it is no longer sluggish at all.
This has saved me a gratuitous amount of battery life when the phone is idle.
Default profile
Max 1Ghz
Min 800Mhz
scaling Conservative
Charging/full profile
Same as default but scales on performance
Battery <50%
Max 800Mhz
Min 400Mhz
scaling Ondemand
screen off
Max 200
Min 200
Scale powersave

Thanks for these, I was looking for a some decent settings. Mine were close to that to start, but I had no idea what I was doing, haha

I had some stability problems with it that I am now fairly certain are related to adjusting the polling frequency in advanced settings. After disabling setting advanced settings on boot, and a reboot, it has not caused the phone to hang once. I am also fairly sure that the phone boots with the conservative governor enabled and min/max frequencies set to 100MHz and 1GHz, even without SetCPU - so the main benefit here is profiles to force lower clocks with screen off, or during overheat or low battery.

CPU throttles itself. Any effects of setCPU is placebo effect

Err if you set the clocks yourself, you can produce a difference depending on what it's catered towards. I'm sure if I set the max clock to 200 (assuming the app works) for all situations there will be a difference.

Does the stock ROM have a perflock like the EVO that we need to disable?
Also, does the stock ROM automatically underclock at times, or???

I've now verified after clearing user data, the stock firmware already sets the conservative governor and allows it the full range of frequencies supported by the CPU. Only benefit from SetCPU should be profiles - reduce max clock when hot or low battery, that sort of thing.

I was going to make a screen off profile of 200mhz, to save battery. Should I bother doing this?
Edit: Nevermind, I'm just going to uninstall it. It's locked up my phone twice already

Default Profile: 800 MHz
Profiles:
Temp > 46 C -- 400 Max 100 Min Conservative
Battery < 40 -- 400 Max 100 Min Conservative
Screen Off -- 400 Max 100 Min Conservative
This now gives my phone life of about 2 days with moderate use (1 hour calls, 1 hour browsing and another 30-45 mins of using apps that need screen on like games, etc)

One thing u got to keep in mind, CPU scales up when woken from low speeds (like when u set for 200 n this takes a second or two). After some R&D i realized 400 MHz when sleeping is optimal with hardly noticeable lag.

well, i have tried playing heavy games like asphalt 5, dungeon hunter, assasin's creed... these all games seemed to work with no lag even at 400 MHz when my battery was less than 40. Most apps I have or used or saw were very comfortable even at 400 MHz. But with multiple apps open, sometimes there was lag, so i set the max at 800 MHz, instead of 1 GHz.
Also, I set my connection to EDGE from 3G. This helped reduce phone from getting heated up with long calls.

I tried using this app myself but uninstalled it after a week. While I'm sure there was some underlying cause, it made my phone never wake up from sleep mode when it turned off.
Honestly thou, I know several android phone owners with s lot of phones That didn't see any real change in their battery life as s result. And based on my experiences, I'd say stay away from it.
Just my 2 cents thou

[Q] Proper setup for Set CPU on Captivate

Hi fellow androiders......have loaded Set CPU and would like to know what if any is the optimum profile(s) setup for the Captivate.....Thanks

I turn my CPU back to 1 ghz if temp > 50
I also go 600mhz max when the screen is off.
I don't see much need for the rest, but I'm curious to see what others add.

What is the lowest the CPU can go on the Captivate?
Sent from my iPhone with the bigger Gee Bees.

Pretty nice app, although I can't seem to be able to go above 1ghz in cognition 2.3B2... But I have set to.
Temp>60 400mgz (I live in the desert)
Temp>50 800mhz(totally nessicary)
screen off= 100-400
charging= 800-1000
and some other little battery things thrown in.

lowest is 100mhz... would NOT recommend setting MAXCPU on anything to that!!
It will idle at 100, but if it can't clock up, you'll never be able to use it. 400 is functional for call/txt.

I never have heat issues with my Captivate, and I don't do any oc-ing/uv-ing. I personally use:
Screen off: Max 200, Min 100, Scaling Conservative, Priority 100
Charging/Full: Max 100, Min 400, Scaling Performance, Priority 75
Battery<101%: Max 800, Min 100, Scaling Conservative, Priority 50
With Darky's ROM and Speedmod K12N kernel, 800MHz cap gives plenty of performance. 200MHz while the screen is off is just fine for playing music in PowerAMP with headset controls.

Setcpu?

Which is the best setting to keep your setcpu for day to day use? Userspace? Performance? Conservative? On demand? Ineractive?

On demand probably.

Anybody else any suggestions

I use interactive... and screen off interactive..

I kept stock myself, Min 245 Max 998 I believe, but here's a thread for this( n1 setcpu)

I have my set CPU to on demand.
But you should also enable profiles...
Such as "screen off" set to 245 for max and min that way when you lock the screen your saving the most power. Also for my own sake I set it for "battery<20% to be around 600 max and of course 245 min, just in case I'm low on power and need to conserve for some phone calls.

SetCpu Problems

Hi im using serenipdty rom 4.3 im using setcpu and i use the profile feature, but now i dont know what happened i set the processor to 800 mhz max and 400 min conservative scaling, and the profile screen off profile to 400mhz max, 400 mhz min, the phone when the screen is on the processor stays on 400mhz and the phone is extremely slow, i dont know what to do, i tried everything, only by removing the screen off profile the phone stays between 800mhz and 400mhz, i undervolt, but i dont think that is the reason...

Stop using set cpu.

Kernel stock And Min free CPU with setcpu (rooted)

Hi
My s5 default frequency CPU are 300 Min And 2400 max.
I have root. stock rom And kernel. I have Read about clocking And if i increase CPU sped in its Min values The CPU should be more reactive. (i have stock kernel for mantain knox To 0x0 And i don.'t need a overclock up 2400 because 2400 is enought i think..) So, if i have 300 Min And 2400 max which Min value Can i set without problems? 400?652?728?or 883?
Now i have 883.. It' ok for CPU or i should have problems ? I Can set more than 883?if yes what CPU Min frequency could i set?
I have set when The Phone is charging or screen is off or calling The CPU turns To normal values (300 Min 2400 max).
The governor i use is stock interactive scheduler row.
I dov'è care about battery. If The change drop fastly is Not a problem for me. I want The Phone more reactive And responsi possible without problems on the CPU ecc..

Shouldn't have any problems, you might experience a bit more battery drain, that's about it. Sometimes when my screen is on, my phone automatically adjusts to 1190 as min, so I don't think you need to do anything.
Stock kernel, rooted

883 is too Hight or i Can set more? Like 960 or 1036 or 1190?i think more that 1190 is excessive.
In My experience when you open setcpu And do Nothing normally The CPU is 300.when you simply touch The screen it increase To 1190 so The 1190 i think is the minimal value of CPU when you use The Phone for operations. So maybe i think i could be ok if i set 1190.
