ok, i searched for the problem i had but couldnt find anything relevant. i hope someone can direct me to it, if there is any already, or give me an answer,
i downloaded Setcpu and ive seen most of people using "conservative" scaling for better battery life, but i dont see that option in the app. i just see ondemand, userspace and performance.
any idea if im doing something wrong?
and also i would appreciate if someone can tell me the settings for longer battery life? wanted to try it but didnt understand that much.
thanks.
btw im using virus rom rc3 with stock kernel.
The governors are kernel specific- if the kernel doesn't support it, it won't show up as an option. In your case, conservative scaling is not supported by the kernel you are using.

oh ok. now i got it. thanks for the info.
Both Netarchy and Kings kernels have "conservative" governors on them. One of the top ways to conserve battery is to make a profile setting for Screen Off where you set the min and max freq to the lowest possible setting. For me though I can go to 128 Mhz, I get too much lag on wake-up and therefore set to 384. Your phone may do better.
Someone also made a thread that describes the advanced settings. Tweaking those can also improve battery life as well.

Recently i've ventured into kernel threads wondering how i can get better battery life on my G2. I consider myself pretty well versed in roms but Kernels are a whole new animal for me.
I have read so many threads im becoming dizzy. If i have to flash a kernel for better battery, which one? I dont have demands for a faster phone. Most of the threads about kernels i have read are all about getting a faster clock. Im fine with the speed of my G2. I just want better battery.
Can some one provide me with some literature on the subject, point me in the right direction, or even better, answer some questions for a noob in this particular subject??
What Kernel to use?
Can i flash over CM 6.1 Stable?
Do i need to wipe before flash?
Any assistance will surely allow me to sleep better at night.
Thank you in advance.
I can tell you im running virtuous 7.2 i find pershoots kernel the best for battery.

If you want great battery life, don't use a sense rom. They're battery hogs as it is. Stay on CM 6.1 and flash pershoots latest kernel. Get setcpu and set a profile to 245/245 when the screen is off.
With these settings I get awesome battery life and I'm overclocked to 1497.

Oh ya i learned through trial and error to stay away from sense roms.
Can i ask you why you overclock? I dont find myself in any moments where i think the phone should be going faster.
I can flash pershoots over cm with no problems?
Can i get a link?
thanks for the response.
Well i lpike sense but only when its ocd sense too sluggish on stock g2 speeds. Also even with ocing and runing sense my bat last just about all day. It sometimes needs a shot a juice if im useing gps or playing a lot of games but thats it.

Decent battery life on my G2.
I'm running htc sence on mine with the pershoot kernal and cpu tuner.I have tweaked profiles and my battery life is better than b4.Example, i took it off the charger(ac) yesterday morning @ about 9:20am & today Thur, i checked the [email protected] 11:50am and my battery is only @ 40%.(1 day,3hrs & 31min's later)not bad.That's WITH moderate use.

So whats CPU Tuner? Do you have some suggestions for how to tweak the profile? Can i get a link to the pershoots thread? Is this the right thread? --> http://forum.xda-developers.com/showthread.php?t=847672
Do I have to wipe before flashing and then reinstall cm over it?
When I went into SetCPU, it always kinda confused me. That could be why I was never interested in overclocking.
I realize I have a lot of questions. Im just a careful and thorough person.
Simple.
@dangabob13...Don't worry about all the questions i'd want to b super carefull as well.First, cpu tuner is a free app in the market much like set cpu except u get more options as far as customizing your profiles.Second you can find the pershoot kernel right with in rom manager.Just go to the download rom section & its the 3rd one down.I didn't wipe and i haven't had any problems.The reason i switched to the pershoot kernel was because i was having problems waking up the screen with HTC sense and the kernel it came with.This fixed the issue for me.No need to b confused it's actually pretty simple.My profiles for cpu tuner are as follows:
Under the "Current" tab: i have the governor set to "conservative" i have the cpu o.c to 1094 MHZ.No need to go crazy over clocking i find this to b fast enough for now. The rest of my profiles:under the "profiles"tab,
Performance:Ondemand-Max:1094 Ghz,Min:768Mhz.
Good:Conservative-Max:1094Ghz,Min:768Mhz.
Normal:Conservative-Max:1094Ghz,Min:768Mhz.
Power save:Conservative-Max:1094mhz,Min:768Mhz.
Screen off:Conservative-Max:768Mhz,Min:768Mhz.
Extreme Power save:Conservative-Max:768Mhz,Min:768Mhz.
Keep in mind i also have wifi,blutooth,sync all disabled as well.I'm not saying this is guaranteed to work for you, I'm simply stating what works for me. Good luck i hope this helps.
Quick question....doesn't CM6.1 Stable have the pershoot kernel already? Also does the Pershoot kernel the one that goes to 1.8Mhz?
Not that I'm interested in going that high, but just wondering.
I OC for games mainly, but also to watch tv and movies, the extra umph really helps. My setup on SetCPU are:
Temp>40.2*C 368 / 245 Powersave Priority 100
Screen Off 245 / 245 Powersave Priority 90
Charging/full 1497 / 245 Interactive Priority 85
Battery<10% 268 / 245 Conservative Priority 80
Battery<30% 806 / 245 Conservative Priority 70
Hope this helps.

I dont have a conservative option under the Governor dropdown. is that important. Otherwise i duplicated your settings. Boasting 27 hours of up time and 40% left is bound to make me jealous ill test it out. Thanks again.
That's strange is your cpu tuner app up to date? I also wanted to mention that my screen brightness is set to 20%,heptic feed back is turned off and so is vibration. Along with a few other battery saving options you should see a difference in battery life.Obviously results will vary.

Ha its so funny. I have the same exact settings. i took a look around and turned off all that stuff. I keep my GPS on because it only uses battery when its being used. But i turn off wireless locations so that its not always trying to centralize my location.
I am new to the setcpu app I am wondering how do I know how much frequency my min and max should be to help my phone out more. Can anyone help me on that plz?

It will depend on which ROM and kernel you're running, but generally, overclocking doesn't do much good for you. I do however run my Main Max @ 1113 and Min @ 245. I then have a profile set for Screen Off Max @ 245, Min @ 245. This has helped a lot with battery life. This is on CM6.1.1 and the SBC stock kernel.
Also, there are the Scaling options. They will vary based on the kernel you're using. Generally, their names speak for themselves, so pick appropriately. I use Interactive when available, or Ondemand as a second choice. If you choose Performance, you will stay clocked at the highest speed until over ridden by a profile, so don't bother with that one unless it's for testing only.
One thing to think about is that Setcpu doesn't play well with HAVS, so if you're running a kernel with that built in, they will be fighting each other.
Also, if you're running a stock based rom with a stock kernel, you will need to disable Perflock if you want Setcpu to be able to really do it's job. So, while in Setcpu, tap Menu > Perflock Disbaler and attempt to disable perflock. Once it is successful, pick set on boot and close that window. Now Setcpu can work properly and you can start saving battery.
If you're primary goal is to get amazing battery life, I highly reccommend you try some of the new SBC kernels that have trickle charging built in. That's what I've been using since they came out, and it is amazing what a little tweak can do for you. SBC Kernel Thread
Im good on everything else except when it comes the CPU thing. I have no idea what the numbers mean when you set the CPU for some reason. To slow the phones resources when the screen is off right? Can anyone point me to the direction of an app that can do this? What about an app that turns the data off once I turn the screens off. A free one.

SetCPU can modify the processor speed and allow you to set a profiles. However, you're running Tiamat so if you haven't changed anything your default governor is smartass which has a built in screen off profile of 128min/384max.
As far as turning data off, check out ultimatejuice. There is a free version that is limited in what it does, but it might be worth paying for. Also, for battery saving, check out my EVO link in my sig for some undervolting mods.
You can set the cpu governor with a program called setCPU on the marketplace. You can further control the CPU by flashing another kernel. What ROM are you running? Stock? I would try the netarchy kernel (newest version) if you're running a sense-based ROM.. I've found it has phenomenal battery life (medium use i get 15-20hrs) and I'm overclocked to 1.152ghz.
A program called tasker can also make your data connection go off and back on with the screen. I'm unsure how to set the profile but I do know thats possible. Try looking around here: http://tasker.wikidot.com You should be able to find something about it.
EDIT: Nevermind about netarchy, did not see your signature on your ROM and kernel.
ok, so ur on aosp and tiamat. try changing governer to smartass. will give you much better battery life, and you won't have to worry about 'numbers'.
btw the numbers are the cycles per second, or the speed the cpu works at. i personally underclock to 537 (998 is stock) to save a bunch of battery, and it still runs perfectly fine for me (cm7 with tiamat)

Plus im pretty much sticking with MIUI....I usually use the 25 vipervolting. Now I'm on tiamat v4.0.3. Are you saying sense I'm using tiamat its already set to smartass, so it'll be unnecessary to use the setcpu app? Also I like savZen to what's the default governor on that? Final question, turning the data off when the screen goes off using ultimatejuice unnecessary if I'm running tiamat? Sorry for the bombarding of questions thanks again

Yes, most of the scripts lower by a certain range. So it all depends on the kernel you are running. Some of my scripts (Extreme, Insane, v2 scripts) specify all the voltages so no matter what kernel you're running, it sets the voltages to exact values. If you can go lower than -25 and you're stable, do it!
I find SetCPU unnecessary. I only have it installed because I use it for testing my mods and things, but I that's the only reason. But smartass is good enough for me, no other governors give me as good batter life. Defauly governor on SZ is their own governor (SavagedZen) it's based on interactive, I believe. There is more info on their site.
Tiamat (or any kernel for that matter) don't turn off 3G when the screen is off. You would need an app to do that.

I couldn't agree more. Setting up a basic screen off profile with a conservative setting is useful, otherwise it actually gets in the way of already built in kernel benefits, actually undoing them in many cases. I stopped using setcpu a while ago and my battery life has not suffered at all.

Whats up guys? I have a question about using the Set CPU app.
Is it really worth it to use this app? Will it actually make an improvement in my battery life?
I don't want to use this app to speed up my phone, but to make it better on battery life.
I know you can set up profiles, but I'm not sure on what good setting would be to use. Can anyone give me some insight on this?
Also I'm running the latest version on MIUI and the Tiamat kernel.
P.S. Is there better kernels to be used then Tiamat?
Thanks in advance.

maybe it's just me, but am getting better bat life with the stock kernal. I ran the tiamat for a few days, switched back and it was obvious to me.
With Tiamat the default governor is smartass, which has a built in setting for when the screen is off, that only lets the phone see a max of 368640, which will save on battery life and does.
Now if you want to get into using your own profiles then an app such as Setcpu can be helpful.
I have been using this and this in place of Setcpu. It's a little faster reacting to the changes form screen off to on. Just another option.
I like the Tiamat Kernels as well as JD's Kernels. They both work well with Miui, at least on my phone anyway.
I've used Set CPU for awhile, but then got away from it. I'm back on it now since MIUI doesn't have a built in OC. I would try the two PacerguyDon suggested. I have used the andrev_oc it is fine. The second one appears to have more functions than Set CPU. Set CPU doesn't allow you to under volt if that is what you are looking for.
I saw that Set CPU is $0.99 on Amazon, if you want it. However, I would try the other two for free and donate to the one you like best.
I have been using JD's Kernel the last few days and it seems to provide better battery life than stock. I originally tried using the Smartass govenor, but had to go back to On Demand. The Smartass was causing screen wake delay when receiving a call.
I stole this from another PacerguyDon's post and it breaks down the different govenors found in most OC apps.
Govenors
Set CPU is free for XDA members. It also does allow undervolting according to their post.

Does anyone have any recommended kernel settings they'd like to share? I've been changing things around a little but I'm too afraid to make any big differences as I don't want to ruin anything. Any recommended GPU clock settings would also be appreciated!
Also, I see people mentioning they're overclocking their phone a lot. Does overclocking on this phone mean it constantly stays overclocked until you change the settings back or does it change frequencies as needed to a maximum frequency that you set?

Hey When you OC lets say to 1800mhz . That means your proccesor can Amp up to 1800 mhz if needed. Your phone will always idle when its a sleep. My setting are 100mhz UC and 1800mhz OC. Gpu is also Oc to 640mhz. I use pegasusq for governor and cfq or zen for scheduler. I also use eco mode . I get very good battery life and performance.
Also...what apps are you guy using for this? Seems most use trickster... Wondering if anyone has experience with others.
Sent from my SAMSUNG-SGH-I317 using Tapatalk 4
I would use whatever the developer of your rom/kernel recommends (which is Trickster most of the time)
Anyone know what eco mode does? I've been looking it up but all I've been getting is this guy's kernel that he named 'eco'
Also, for anyone reading this thread with a similar question to mine I'd heavily recommend using Zen over CFQ as a scheduler because it's much smoother and no jitters/stutters (at least in my experience)
Sent from my SGH-I317
I'm curious what Eco does as well. Tried looking it up, but didn't find anything useful.
Trying out Zen...been getting some annoying hangups and jitters with this kernal. UC 100 OC 1704. And FYI...I've used the stock clocks and still got the same lag and lockups and screen freezes. Also tried on demand gov.
Could it be that ZRAM is enabled? Not quite sure the benefits of it.
Sent from my SAMSUNG-SGH-I317 using Tapatalk 4
Do you have eco mode enabled? Also, maybe you should look into Seeder. It sounds like it's perfect for the kind of problems you're having. Or you could change your minimum voltage from 100 to 200, I heard 100 can be kind of buggy sometimes
