help me with setcpu profiles - Epic 4G General

can someone help me with set cpu profiles. I think I set it correctly, but battery life not what i'm expecting. i'm running ACS newest rom. I have it set to ondemand 100-1000 as the base. then I have a profile for screen off that specifies 100-200 conservative. so shouldn't it basically just be sitting at 100-200 most of the time since the screen is usually off? when I check it seems to be using 1000 an aweful lot which is weird for something that isn't using that unless the screen is on.

Those settings look right to me. I bumped my idle up to 400 though incase any background services need it. If its too underclocked it will stress the battery even harder if a service needs more from my understanding. Try calibrating your battery and downloading juice defender. I caught some flack in the ACS thread for these two things but after 7 idle hours last night I only lost 6%. Having the screen on is the biggest drain but there may also be other factors at play in your case.

Phone not waking up after Set cpu?

Hey guys any of you running set cpu? i have a profile set so that when i turn the screen off it drops the cpu down to 250mhz. I'm having a issue where sometimes it dosen't wake back up. Anyone else had this happen?
I noticed this Tuesday. They don't play nice together...yet. setcpu needs info about the hummingbird cpu in order for it to work. Setcpu's dev will most likely have an update for this soon. For now, i'd uninstall it and keep an eye out on the program for an update.
sweet glad to know that its not just me.
I had this same problem with the Overclock Widget for the same purpose (shut down CPU while screen sleeps)... After removing Overclock... I have yet to have a blank screen situation.
I've got mine (SetCpu) set to the "on-demand" preset. Have not had a wake up issue yet...
SetCpu seems to be quite different on the Epic than on the EVO. More presets and options....

Scratch that - this morning the EPIC didn't wake. Battery out, back in, screen off, didn't wake.
Uninstalled SetCpu, all is back to normal (except for the crap battery life of course).
Emailed the SetCpu dev, he thinks it is related to the kernel. I'll try out a custom ROM/kernel as soon as one is ready to see if it resolves the issue.
I'm not having any issues with my epic and setcpu, right now the screen off profile is: 200Mhz, ondemand, & priority @ 100.
In the Vibrant forum there are numerous threads in which the OPs screwed up their phones using setCPU. I'd stay away from apps like setcpu, juice defender, task killers, etc.

i agree with staying away from set cpu but juice defender and task killer are essential to me getting decent battery life on my epic lol

How long have you had it in use? I was cool for a day, then it wouldn't wake up.
From the dev: "The scaling is the issue, I think. Ondemand crashes the Galaxy S, but conservative doesn't seem to."
I'm ready to hit some customs, battery life just isn't good enough so far.

I've had good results with the conservative setting of SetCpu. With ATK and SetCpu, I had double the prior norm in battery life. Over past 2 days I've gotten over 12 hours and I plugged in before full drain both days. Started at 6:30 this morning, should get a good read on potential. Expecting 15+ which would officially resolve my battery issues.

I was using conservative on set cpu when i got the lockup

I have been using setCPU and ATK since 9/2 with no problems so far. I have it set on conservative and 200 when screen is off. I been getting around 10-12 hours with moderate uses. With little use today I am at 9 hours with 50% battery left.

I ended up at with over 15 hours logged and ~15-20% battery remaining last night. Good enough for me. Bluetooth/GPS/Wifi on all day, 4G off, screen turned down, ATK.
No Problem with CPU Set at 200
I kept having the same issue until I changed the lower limit to 200 and used Conservative setting.
Now, no problem at all!
I think I tend to agree with you.... I tried running the phoenix kernel on my epic, and the phone would not wake up (was told it was because phoenix defaults to 100/1000) and was told to use setcpu.. tried it... wow... what a disappointment.. setcpu kept giving me way different readings everytime I ran it.... not nice at all....
I've since tried this again, this time, placing setcpu.txt on my /sdcard will see if this helps..... so far, so good......
I have a screen off profile set for 400mhz max 200mhz min with conservative governor. My main profile is 1200mhz max and 200mhz min. This is with the mixup kernel and I never have any lock up issues
Sent from my Emotionless Beast of an Epic using the XDA App
i have my min at 200 for all of my profiles. My screen max is 400 and it keeps my phone from waking up. It's set to conservative. I'm also using it with juice defender, so i'm not sure if that's the culprit or what. Does anyone else have any suggestions on settings for screen off?

Interactive Vs Conservative Governor? CDMA Battery Life Tips

What is this nonsense people are saying about 4 or 5 hours with screen on and their phone is still at 20%? GTFO.... Usually I would say about 3 hours of screen on and i'm dead. I can get like 18 hrs or so lightly, and by lightly, I mean only using it for a few text and check email, maybe some fb just to check inbox and such, lightly, using the phone (with my reception).
I know the Fascinate is better hardware, and I switched for the GPU among other reasons (2 of em for free...=P) but, on my nexus, I still find that the interactive governor ramped up to the max freq. (1113Mhz) less. Of course, I am using the 1150 nonvoodoo from geeknik, but I doubt I will make it 4 or 5 hours of screen on time.w
How can you use the phone, with the screen on, and not do anything that uses the battery. I mean, without cyanogen, it was cool that I can make it through my day, easy, close to out of box (getting to superclean dj05 is about 100 less flashes that I made it through with the n1/sense/cyan nightlys/test roms/etc.).
But now I want more, the price I have to pay I guess for the .3 inches of gained screen is not using the phone heavily in order to save battery!? That sucks. I used to hammer my iPhone and I rarely made it through the day, but I hammered it with atleast 4 or 5 hrs of screen on time sometimes, and it would make it atleast 8 hours... that thing would idle wayyyy better on GSM Edge than CDMA I guess, as with my T-Mobile N1, it idled wayy better, than this CDMA phone. Is there a way to put it on 1x instead of having it always on 3g? There isnt a setting to uncheck, and you cant get in *#*#4636#*#* on CDMA. I tried that immediately after unboxing to get off 3g when I wasnt using net apps, and usually that gave better signal on GSM, saving battery.
Check out my interactive battery test on my N1 that I did, the interactive setting eventually fell out of favor because it ramps up to the max... instead of ramping up accordingly like OnDemand, and not too slowly like Conservative. Again, why does Fascinate use conservative?
http://forum.xda-developers.com/showthread.php?p=7370179 thats my Interactive Governor Battery Test on my N1 I did in the summer time...
I just wanted to start this thread so we can get a consensus on what works best, and for charging this battery. I used to charge my N1 an extra 1.5 hrs with it off after android says it was at 100. That way it idled on 100 instead of immediate drain. An extra 3 or so hours of battery life if you use it right.
CPU governors control exactly how the CPU scales between your "max" and "min" set frequencies. Most kernels have "ondemand" and "performance." The availability
********I want to be able to choose between ondemand and powersave when my battery gets low. On this phone, as I did with the N1.
ondemand - Available in most kernels, and the default governor in most kernels. When the CPU load reaches a certain point (see "up threshold" in Advanced Settings), ondemand will rapidly scale the CPU up to meet demand, then gradually scale the CPU down when it isn't needed.
conservative - Available in some kernels. It is similar to the ondemand governor, but will scale the CPU up more gradually to better fit demand. Conservative provides a less responsive experience than ondemand, but can save battery.
performance - Available in most kernels. It will keep the CPU running at the "max" set value at all times. This is a bit more efficient than simply setting "max" and "min" to the same value and using ondemand because the system will not waste resources scanning for the CPU load. This governor is recommended for stable benchmarking.
powersave - Available in some kernels. It will keep the CPU running at the "min" set value at all times.
userspace- A method for controlling the CPU speed that isn't currently used by SetCPU. For best results, do not use the userspace governor.

Thank Samsung for breaking ondemand on every sgs phone.
Sent from my SCH-I500 using XDA App
Well what else can you contribute to this thread? Thanks for letting me know that the ondemand is just broken on galaxy s phones. So basically its interactive ... or laggy UI experience. And if you've never used a ondemand kernel, you wouldn't notice the difference but i certainly do. It just takes too long sometimes for it to wake and other things. I have my screen off at 400 mhz but still that is higher than the 256 i was using on the nexus one and it used to wake immediately.
I was reading today and I found that ondemand is pretty much the way to go so i wonder if we could bounty up enough would somebody unbreak it...

You are doing something wrong. Conservative is not choppy on my device and the CPU will always ramp up faster than a human being can judge the response time.

My phone makes it the entire day with heavy use, this means about 20 - 10 min phone calls one or two lasting 30 min, texting my wife all day at work, checking emails, and angry birds for at least 1 hour a day i love that game but I suck at it lol. Something that I found is that the phone will last almost an hour of being on the phone after it hits 0%. In my pocket it lasted 4 hours at 0% the day before yesterday. I thought maybe this is on purpose so you have more then enough time to make it to a charger. When I first downloaded angry birds I played it for three hours straight with the screen at full brightness (i always keep it at full brightness, looks prettier that way) I know it was three hourse because it was while i was waiting at the hospital I got there a little before 7 and wasnt called until 10. Overall I am very pleased with the battery life of this phone not so much with other aspects but battery life and lag never came into my mind as a complaint for this phone, except with all the stock touchwiz stuff.
As adrynalyne said, CPU's scaling changes faster than human's perception. It's your phone or setting that's having an issue.
4 hours at 0%?
The little graphic samsung gives you in the stock battery is misleading.
In my brief experience with it, I got the following impression.
full battery graphic: you have between 100% and 75% left.
<full battery: 75%-50%
Half battery: 50%-25%
low battery: 25%-15%
empty: 15%-0%
This may not be quite right, but you get the idea. It has been a while, but stock battery is pretty misleading. Samsung reports [more than] half empty [always] as being half full!
Want a more trailer indicator? You can get an accurate battery mod (via a theme for instance) or you can download an app to check current battery % left (i use osmanager - do not leave this app running in the background! )
Assuming your phone lasts 27 hours or so unplugged with no use at all, I would say 4 hours at "zero" battery makes sense.
For my phone, the display uses an average of 3.5x as much power as the rest of its functionality (total of 1/4.5x lifespan in active use vs. pocket)
Swyped w/ XDA App. When in doubt, mumble.
I meant "reliable" not trailer.
I get about 5 hours of screen time with little voice calls on wifi.
I don't know if I am just one of the lucky ones but my phone gets between 30 and 36 hours on a single charge, having even made it to 44 hours on a very rare occasion and that's without setcpu profiles even set.
Wtf... my phone is brand spanking new and I get about 4ish hours of screen time on a full charge, with the lowest brightness + screen filter app set at 50.6% reduced light. I get like 3 hours without screen filter on.... wtf. This is running on conservative or interactive the whole time..... wtf!!! With wifi on and 0 extra screens or Widgets using launcher pro without animations... wtf!!!

I wouldn't worry about these guys coming in here saying they're getting 2 days of use either. They're not using the phone anywhere near as much as you. I've had 3 of these things and know 2 guys with them. They all got the same battery life. You don't see anyone posting any screenshots, do you?
Me and my gfs fascinate gets about same battery life in our apt and hers is still DI01 and i'm on DJ05... she has jts 11/16 kernel and i have the 12/21 voodoo5 and we get about the same battery life... dependent on how much we use the phone. .... so just use your phone, and charge it as necessary... its better for the type of battery we use anyways in our phones... **************************************************************************************closed.**************************************************************************************

Dj05 vs dl09

Can an informed person contrast these 2 roms for me please
Sent from my SCH-I500 using XDA App
I am not informed but I can tell you dl09 broke my GPS. It takes 10 minutes to get a sporadic lock. I had to revert to dj05 in order to fix it.
I'm curious too. So far, I haven't really seen anything, so I haven't upgraded.
I've been running it for a week now. Looks like the GPS doesn't lock as fast anymore compared with DJ05. It also currently has me on the wrong side of the freeway by my office so it's not that pinpoint accurate either. I think the WiFi is faster & stronger on DL09 than DJ05. It's probably not worth making the jump to DL09 but I'm not going to revert to DJ05.
Dj 05 works better...everything works on it. Dl 09 not so much...
Radio DL09 gps did not lock as fast wifi about the same on each.
Move back to dj05 working great for me.

You are correct. After 8 hours I'm at 72% battery remaining. I think it's because of the under volted kernel.

I am starting to not believe that undervolted kernels actually do not save any battery.
I've noticed this pattern with all of the kernels that claim undervolting.
But if what you're saying is true, you can run Adrynalyne's kernel with DJ05 and get better battery life.
I think that's what I'm running. I'm also running a Gingerbread Theme which displays everything black when possible thus reducing battery consumption from the screen, but my phone is still sucking for battery life.
2cents.

Do you mean you don't believe they do save battery?
I had a UV kernel on my phone for a little while, and there WERE noticeable gains in battery life. It wasn't anything crazy, but running the same programs and the same activity over an 8-9 hour span (sitting at work), I had more battery left at the end of the day with a UV kernel than I did running a normal one.
I didn't really pay much attention to it until I forgot to charge my phone on my way to practice one night. Phone would usually be *****ing to be charged, but it was doing good.
I have been running a lot of different UV kernels over the past few weeks, and there is a point where you go from the UV helping your battery and it hurting battery life. From my testing, as the size of the UV increases, the processor will reach a point where it can keep up at a given clock speed and will then move up as needed. It will get to a point where it's staying at 400/800 clock speeds more often than the 100/200 clock speeds, and the effect is negated.
I'm sure this point is going to be different on all phones, but for my phone is somewhere around a -100mV drop from stock voltages. It will help your battery when sleeping since your phone isn't doing anything, it will use even less power, but as soon as it tries to do something again, the battery life will tank. I also used PowerTutor to look at the usage trend for the CPU, and the system was using more power on average for some larger mV drops. I also started to notice lag as the drops increased, likely due to the processor being unable to keep up.
At the moment, I'm trying to see how a big drop on just the lowest clock speed, and then less of a drop on 200-1000 does. I also made a few adjustments to the scaling factors to help reduce lag at 100/200mhz and keep it in the lowest possible clock speed when running. So far, it seems somewhat promising, though I've only been running my current test for a few hours.
Voltage has nothing to do with how much work the processor can do in a clock cycle. Higher voltages allow faster clock speeds, but the voltage itself doesn't matter if the circuit is synchronized (i.e. has a clock). It's just more likely that you won't be able to run at a given clock speed with a lower voltage, but that will just cause glitches and instability, not less work being done and needing to run at a higher speed.
I realize that it shouldn't matter, but it did. I'm guessing that the lower voltage preventing the CPU from running at the actual clock speed, causing it to high the usage threshold sooner. I could barely keep the phone at 100mhz after restarting with just SetCPU running in the foreground. I didn't look into what was happening much because the battery drain was pretty bad, so I went on to a new test.
Also DL09 is officially supported by vzw....

oc'd phone heating up during normal use and poor battery life

Well ill start off by saying I'm new here and this is my first post. I'm also very new to this stuff and have a lot to learn. A buddy of mine recently rooted and overclocked my phone using the sense 2.6.32.21 1.5ghz oc/uv kernel. I currently have it set to 1.19 max 768 min and am experiencing temps above 107 running emulators and just web browsing.. I am also seeing pretty poor batt life even using battery booster and advanced task killer.. any help is greatly appreciated!
Battery apps and task killers tend to have the opposite of their intended effect on battery. Android has a built in utility to watch battery usage, why do you need a 3rd party one? Also do some reading on task killers, you will see why they are unnecessary on Android. I've stopped using one and my phone runs faster and more stable than before.
768 min is VERY high. Might explain the heating and battery life drain quite a bit.
Try this for me, please. Set your governor to interactive and drop your min down to 245. Run that for a whole charge. You may be surprised.
Sent from my PG06100
Also, I second the post above me. Advanced Task Killer and anything like it ultimately cause more harm than good. Battery apps, such as Juice Defender, also shouldn't be necessary. Although, it is YOUR phone.
Thanks a lot for the replys. I set the min to 245 and am seeing serious changes in temps. I also uninstalled atk but installed appkik. I am also still running battery booster but may get rid of it soon.. I feel like this phone should have better batt life. Any suggestions?

well they gave some suggestions. which it seems you dont want to listen to. you dont need task killers of any kind

No disrespect here, but seriously, if you don't know what and why you're overclocking, don't know the inherent risks, etc, why are you doing it?

because all the cool kids are doing it smurf...duh.
But seriously, min. should not be set at anything greater then 245. Only use performance if you are benchmarking. Default at the moment should be interactive.
Just gonna add my 2 cents in from personal observation....after doing some reading on overlooking and stuff I've noticed when going into the different ## modes, the shift usually drops its processor cycles to pretty low numbers in the 200-300 mhz range when its just in standby or not doing anything...it only kicks it up when you need the power. So the heating up is probably caused by constantly running at what used to be its max territory...PLUS youre going above and beyond the original limits/specs at a constant so it never gets to relax even when the phone is idle...I hope that makes sense. So as one poster mentioned keep the min at the stock setting and if you really want to/need to then raise the max mhz to whatever your phone can handle reliably. Correct me if I'm wrong anyone who is more into the overlooked setups. Me personally, stock has been able to keep up with whatever I have thrown at it after 30 days and still getting 25+hrs on one charge.

I currently have it governed at 245 max screen off. Running 1.2ghz max interactive with no task killers or batt savers. Batt life seems to be somewhat better but temps still creep past 105. Thanks a lot for the info
alittle off of the beaten path, but i tried runing 245/1801 interactive on evervolv and noticed alot of random reboots. set it back at on demand and am having good luck with that. why is everyone leaning towards interactive??
Excuse me if I am wrong it's early and im too lazy to reread up on it but I believe the difference is with on demand there is a slight delay(second or two) and it gradually kicks up to where it needs to be where is interactive is a spike the second you need it...

If you look at your cpu's scaling history when on the two, TYPICALLY, you'll see a whole lot more time in higher frequencies using ondemand.
That's not to say, however, that with some devices and some kernels they will act the same.

Quest for the best battery life.

Day 1:
Flashed Simple and Clean v1.3
2.6.35.7 speedmod test3 k2 kernel
Juice Defender Ultimate in Agressive mode.
Batterylife: 11 hours. Lost most of the life when the phone and I were both asleep during the night. It went down from 100 to 38%...
PS: If anyone wants to give me their set up so I don't have to spend so long on this quest, that would be appreciated...
There are 2 more threads with the same topic, with much more info. Also, we know nothing about how you use your phone, except that you have huge wakelocks. Not really helpful tbh.
care to point out those threads for me?

PS - Ditch Juice Defender it uses up as much battery as it saves, trust me this is fact.
I did. I tried some of the solutions posted in some threads like using speedmod + clean n simple, and also lightning v6.1 and ninphetamine kernel; doesn't work.
I used to have the Galaxy S Vibrant before I got the S2. I swore by Juice Defender. I would get on average 45-60% more battery depending on usage (phone was rooted with OCLF installed). My S2 gets an additional 2-3% more life while running juice defender. Takes more than that to run it. My opinion, remove the app.
I am running sensation 1.9 rom and hardcore speedmod kernel. I work oh average 11 hours a day. Phone isn't used much during that time. Wifi is always on and by the end of my shift, it's at 94% or so.
When I get home, my phone is put through some heavy use. Facebook, youtube, texting galore and internet browsing. I always have 25-30% battery left at the bare minimum written I go to bed at 6-8 hours later.
In my personal opinion, this rom and kernel combination give me the best power (4700 on quadrant), best options (configuration got nearly anything) and best battery life (phone lasts all day with ease). I would recommend this to anyone in a heartbeat.

I'd recommend the Hyperdroid rom. A lot of users (including myself) have hit 5 hours screen on time (most I've seen is 7 hours). Phone can easily last a whole day, just need to check for wakelocks using BBS. 60% overnight is ridiculous lol, you should really be losing 1% every 4-5 at least unless you have loads of people ringing you all night
My setup
Rom: Hyperdroid 2.9.0
Kernal: TWD2.5
UV with voltage control
200mhz - 1200mhz
Sio I/O - Lulzactive governer
Max Screen On Time - 5 Hours 28 Mins
Facebook/Whatsapp Syncing
Read the guide i posted yesterday, its a bit long, but will definately save you battery life.

Also my setup is in my sig - very fast, very slick and above all great battery life (range between 20hrs and 28hrs moderate use)
I read the long thread. It has some points in there I didn't know about.
Will try HyperDroid Rom.
Tried Sensation. Battery life failed for me with that ROM. Will try it againwith speedmod kernel if HyperDroid doesn't work...
btw, what governor is the best for Hyperdroid?
i use
check/leo rom v 3.1.1
siyah kernel 2.2 beta6
ice cream sandwich theme
the kernel is set at smartass v2 governor
1.4ghz - 1300mv
1.2ghz - 1275mv
1ghz - 1150mv
800mhz - 1050mv
500mhz - 950mv
200mhz -900mv
100mhz - 875mv
my sgs2 doesnt like undervolting so them settings should be safe to use on most sgs2 handsets
i then have the following profiles
screen off 100mhz -- 200mhz
charging 100mhz -- 500mhz
in call 100mhz -- 500mhz
battery at 60% set cpu to 100mhz -- 1ghz
battery at 30% set cpu to 100mhz -- 800mhz
battery at 15% set cpu tp 100mhz -- 500mhz
getting excellent battery life with my sgs2
ive also frozen any apps i dont use via titanium and used a start up manager to stop certain programs starting at boot
i used to use juice defender but on the sgs2 it doesnt seem to wrk as well at all
i was getting wakelocks from facebook chat draining my battery so i have installed an app to auto close that when the screen goes off and that has saved me more battery and kept wakelocks down
as other users have said its all about how you use your phone , the settings above might be useless if you have lots of background tasks going on as a screen off profile off 100mhz -- 200mhz may not have enough power to do your background tasks however when my screen is off i want my phone to go to deep sleep and not consume power etc so a very low screen off profile suits my needs as does a low charging profile as i dont use my phone on charge and 500mhz max power suffices my needs for when the phone is charging
same goes for setting a battery % profile i know when my battery is at 15% i wont be playing high end 3d games so it makes sense for me to try and save battery and limit the cpu to 500mhz at that battery percentage but other users may want full power all the way till their battery dies , it all depends on what you want and do with your device
Day whatever:
Used Hyperdroid ROM: Battery Life is AMAZING!
Using their 2.5 TW kernel as well...
The first thing I did was restore all my apps with Titanium Backup, but then I got crappy battery life, so I reflashed the ROM but this time, I didn't restore any apps.
I got amazing battery life!
So it was an APP's fault!
yeah sometimes apps are rogue. Hyperdroid has an awesome kernal though, someones just hit over 8 hours screen on time with stock battery which is amazing. betterbatterystats would show you apps that are causing wakelock problems. I do use some app called gemini just so I can stop apps loading from boot (haven't been bothered to search for autostart apps). Fresh wipe is good sometimes though, fresh and clean is the way to go unless your upgrading from the same line of roms
