How long does it take the n1 to hit standby time after locking the screen? On set CPU I got standby's min and Max at the lowest settings. I think after I get somekind of notification the phone comes out of standby even the the screen stays on.
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

As far as i know, there is max cpu freq which is 1ghz.. and when we sleep the device, the cpu running on min freq, which is usually 300mhz in some custom rom (correct me if i'm wrong)..
and how about if the device is on wake lock, for example running IM with screen off, is the cpu is running max or? Can I change this freq? I'm using zeus..
A wake lock prevents your phone from going in to deep sleep.
When a wakelock aquires when screen is off it is running on 300 mhz that is the lowest.
emm so you mean that wake lock and screen off, that's using the min freq (300 mhz), so how about the deep sleep, what is the freq? it should not be zero, right..

I don't relly know but it is veeeery little.
I see my CPU works on 40-50% in idle mode without turning on applications and stuff. I also noticed that the frequency is varying constantly and onle 2 cores are ON, the others are stopped. I think that all of the cores should work in similar frequencies and the CPU load should be around 10%.
Let's see what is the CPU work of the others......
Just installed the app. All 4 cores are active but they seem to be sitting around 300mhz jumping up to 1400 or 1190 as they cycle.
29% cpu load.
Running BBS tho, 300mhz is where my phone sits most of the time and the cpus have no issue going into deep sleep.
Hello, I'm using Titan Stock ROM and it was working quite OK, but I noticed that with high CPU usage during longer periods of time (Like when you are calling on Skype with both webcams on) after like 5 minutes (depending on ambient temperature) the CPU throtling kicks in and you can barely end the call because the whole GUI of Android gets completely unresponsive.
Quick questions:
- What is the maximum "safe temperature" for the CPU to not break? 60ºC is way too less.. as it gets easily to that temperatures.
Now in hope of getting this a bit fixed I recently installed the "Stellar Kernel". I set the CPU settings as recomended on its kernel page (Undervolted to Min Freq. 98MHz and Max Freq. to 1190MHz). Now its just a nightmare. It overheats even quicker.. and when it throttles you can just pray to do anything.. (I changed finally to Min Freq to 385MHz but that doesn't helps much).
And on the other hand thanks to the underclocking the phone doesn't wants to wake up during minutes.. which is quite unpractical when somebody is calling you.. you can hear the phone ringing but you cannot accept the call because the phone doesn't want's to wake up. But that got somehow fixed putting it back to the Min Freq. +300Mhz.
Just want to know if somebody knows about some magic setting which allows the phone to function properly during longer time.. as far as I'm aware 1190MHz is the original maximum Freq. of this phone so no overclicking is done here. So it looks that the only way to have it working somehow decently is to underclock the maximum frequency and leave the minimum frequency high enough to work properly. I don't really care about battery anymore, as I just need the phone to be functional, and as it is now it's just not. Any advices? Thanks for any reply.
You probably have a hardware problem

acquire kernels and other que rooms have different governors Study on them and the Best That was enough pro you and your needs .
I think this will help you , give will take this need to manually change the clock all, the governor will operate according to its governor preferably .
