how to save battery life when using setcpu?
same that:
Firstly, this is the Android Development Section, so, you have posted this in the wrong section.
Anyway, to the topic, I just watched the video. I don't quite get what the problem is. What part of the video are you unable to follow? You can keep it at the same levels depicted in the video, but, a few of my suggestions:
* Min at 691 is too much. Keep min at 245, it will save battery even when screen is on
* Screen off values are too low. In my personal experience, if it is kept so low, the phone hangs when an incoming call arrives. So, after much experimenting, I have seen that keep the min value at 245. Anything below that can hang the phone. (Obviously many people do get it working fine at 160 MHz, but, this is my personal experience with my Wildfire)
As for the settings under the "Advanced" Tab, I am not having that many settings in my version of SetCPU, so cant really comment on that.

i use ondemand and it works well for me
my settings are 652 max 245 min on performance, not one freeze and getting 2 days plus from a charge

I'm quite rookie on this with cpu and stuff. But, I've read somewhere that the "perfomance" makes that its always running on the max Mhz. So whats the point of having the min on 245 then?
I'm just asking to learn =)

As far as I know you're correct and performance will simply cause the cpu to run at the max speed, the same as setting min and max the same (except its meant to be slightly better than that as it doesn't bother spending cpu cycles figuring out if it should drop the cpu speed to the min)

i have mine running at max all the time works great
i have mine at min -528 max -528 when the screen is on
when screen is off i got it at min - 128 max - 245
thing is i found that i can make the min even lower and the max up to 998
i wanna know the highest i can set it to so i can get full performance

im not too sure about that one but i would love to run mine at 998 lol
so overclocking works now that we have the kernal then ?? cuase it wouldnt work without the kernal before right ?

I would like to know how you did this as well
im not sure if im doin it correctly
but i was just goin through the settings on overclock widget and went to advanced settings and went to "click here to define" and it has all frequencies from 19200 - 998400 you just gotta check them in order to use them
Yeah, with our pre-source kernel, overclocking is not possibly because dynamic clocking is enabled in the kernel, so it automatically adjusts the clockrate.

So basically the Overclocking Widget is useless until we get a ROM with the new kernel source? Oh well, won't be long.
I'm looking to improve my phone's battery life and was curious to know what some of y'alls SetCPU profile settings were.
I don't currently have any set up right now, I just simply have been using Max 1000 Min 800.
Thanks for the help.

I have a few thing set up. My main settings are 1000 Max, 300 Min. When the screen's off, I have it at 600 max, 300 min. And when battery life gets below 35%, it's 600 Max, 300 Min. I haven't done any testing to see how well it works, but I think it helps.
Alright thanks, I'm going to give these profiles a try.
I've been using Max 1000 and Min 800 only, with about ~15 hours of battery life. (This is without talking on the phone very much, but texting, twitter, and web browsing)
These profiles you shared with me have worked great on my phone. I've been talking on the phone more and just using my phone more often in general as well - with longer battery life.
I've gone from ~15 hour for a full battery to 24+ hours.
Thanks for sharing.
If u install overclock.lo and set scaling u can run 1GHZ at 34 volts instead of the stock 66

Cool. Glad I could help.
I was wondering what would be considered optimal settings for SetCpu. I amn running BaconBits and am not sure how I should do the settings.
Any help would be appreciated!
Thanks.
i have mine set at:
Profile 1 : 806 MHz max, 245MHz min, On Demand, priority 50
Profile 2 : 245 MHz max , 245MHz min, On Demand, for when the screen is off, priority 50
if i change the MHz, i change it higher on profile 1 for whatever i need it for then i just scale it back down to 806 when i am done...
Mines pretty much the same as the one above save for max clock speed being 1500Mhz.

I have my scaling set ondemand, have setcpu set at boot, with 1497 max and 245 min, with profiles for various states of the phone.
My profiles:
Screen off: 245 max, 245 min - Priority=100
Battery temp >104: 806 max, 245 min - Priority=90
Battery <10: 245 max, 245 min - Priority=80
Battery <20: 368 max, 245 min - Priority=70
Battery <30: 768 max, 245 min - Priority=60
Charging/Full: 1497 max, 245 min - Priority=50
I get well over a day of use, even with moderate-heavy usage, even with my overclocking on Evil's Sense ROM.
If you search google for an "overclocking 101" thread you should find a rather large ongoing break down of setcpu and the most efficient way to use it. I believe its on one of the droid forums, awesome info.

By all means, have at it!
Main profile: 245 - 1017 on demand
Charging/Full: 1017 - 1017 performance 90 priority
Screen Off: 245 - 245 performance; mainly as this mode will bypass the need to poll/sample for CPU speeds, thus reduces some CPU load. 100 priority
Battery < 20%: 245 - 768 on demand 75 priority
i decided to put the SetCPU widget on my homescreen last night so i could see if the profiles were actually changing as my battery ran lower... and my phone got reaaaalllly sluggish to the point where i would have to wait a few seconds for it to flip back and forth between screens... i deleted the widget thinking that might have caused it, but it was still laggy... so i unclicked on the profiles for battery and got it back to 806MHz and it was fine again...
im guessing that it supposed to slow down the phone when the CPU drops below 806MHz but i didnt think it would be that bad... anyone else experiance this?

What are the profiles you are using? The ones you copied shouldn't have run into any conflicts... except when you're under 20% battery where the CPU is throttled under 368.
What is your powersave bias?
Speaking of powersave bias, could anyone tell me some optimal settings for the setCPU advanced tab? Don't mean to derail this thread, I've just never used that tab.

I believe i was right at 20% batt or right below,so that could have been the issue... I havent messed with anything on the advanced tab as i dont know much about it, the powersave bias is still set to 0

does anyone else feel that their battery lasts longer without using setcpu at all? I mean I love what setcpu can do but in terms of power efficiency, even without overclocking, for some reason I feel like my battery last longer without it.... or am I just crazy?

I used to get about a whole day without setcpu. With setcpu, same amount of usage, I get well over a day and a half before having to charge it up.
Hey everyone,
i think it would be interesting if we collect some SetCPU Profiles.
The App you can find here:
SetCPU for Root Users [2.1.0]
Maybe someone has found allready a good Profile for saving battery but having enough CPU-Power for a smothy work on the Legend?
I have used this Profile for a while, but i think through the overclocking there´s to much battery waste and no really noticable better performance with the apps i use.
Temp > 40° Priority 100
122min | 245max
Screen Off Priority 70
122min | 245max
Battery < 20% Priority 60
122min | 480max
Battery < 50% Priority 50
122min | 600max
Battery <101% Priority 40

That is all
122/768 ondemand....
Is interactive better than ondemand? I mean from fast response/battery life POV...
Main
787 max, 245 min, interactive
Battery 40%
600 max, 245 min, interactive
Screen Off
400 max, 245 min, Ondemand
Screen Off and Battery 40% both at priority 50

I read this in an other board:
From what i've read, "Interactive" is a bit more aggressive at ramping up CPU speed based on load, and is slower to drop off to "idle" speeds once the demand has passed.
"Ondemand" is a bit more conservative in the way it reacts; and will drop back to "idle" speed more quickly.
"Interactive" makes the device significantly snappier, at the cost of battery life. "Ondemand" will last a bit longer batterywise, however; the device will seem a bit sluggish at times.

Can anyone tell me the differences between ondemand, performance, interactive etc.? I can't seems to find the comparison between these in google, xda etc.
Please help me! I'm sure there's people out there who wants the answer as well

I read in a post elsewhere that
"but you have to look at your battery.... it will increase battery drain... ( i set max cpu 96 mhz when screen is off and set cpu 1152 mhz when screeen is on... that saves battery an my hd2 is flying with speed when i am using it, and i decreased cpu voltage a little bit)."
Where do i find the settings to set max cpu to 96 when screen is off??
Thanks

SetCPU's good. @OP, the SetCPU Dev is an XDA member and provides it for free from XDA so if you want to search for it and download it from the original thread you can. If you want to support him then please buy the app from the Play Store.
Also I personally feel that the advice you've been given is quite poor. 96MHz max with the screen off is definitely too low. I keep mine at 128 min and 4 something max, that way the battery usage is low but I get a fast response when I unlock the phone. With 96MHz max you're going to get tonnes of wakelocks. I tried to set mine to be at 128MHz once then tried playing music (with the screen off) and the phone froze, so I reckon with 96 max any background syncing or in fact any background processes could result in freezing.
