[Q] cm7 and setcpu update

[Q] cm7 cpu setting or setcpu?
well atm i am running an evo 4g with cm7 and i just switched my kernel to savaged zen and it's running great. my phone was rebooting on its own w/ the regular cm7 kernel i think its b/c i was using setcpu and people are saying it messes up cm7.
so i was wondering if anyone knew if i can use setcpu with cm7 and savaged as the kernel or if it's possible to make profiles on the cpu settings on cm7 i saw some1 post somewhere that you can but they never explained how.
p.s. please also visit this thread on battery life

AFirst of all, all SavagedZen kernels are Havs kernels (as far as I remember, I'll double check in a few). Anyway, if you are using a Havs kernel, changing cpu settings is pointless/counteractive. I would either leave the settings alone or switch to a no-havs kernel. You can check in settings>about phone.
EDIT: However, if you must mess with the settings, you can find them in Cyanogenmod Settings under Performance Settings. I don't know of a way to set profiles from that screen, though - only max/min & governor.

hi i have an evo running cm7 and i had setcpu and my phone kept restarting however i looked up setcpu again in the market and it said that they just ran an update to stop the problem with cm7, does this mean that setcpu is better to use than the cpu setting in cm7?

You shouldn't need setcpu use the cpu setting in cm7. They put it there for a reason, those guys are sharp!

I still use setcpu because I like my screen off profiles etc. You should update your setcpu if it prompted you to. I think the latest changes were for cm7/GB.

Yes but it doesn't let u make profiles unlike setcpu, or does it?
I believe the profiles is definately the most useful

I believe the SavageZen governor is a specially tweaked/optimized version of the SmartAss governor.
And if you use Smartass/SavageZen governor, I think it also automatically undervolts when sleeping, and essentially mimics what a screen-off profile in SetCPU would do.

In CM Settings, go to Performance Settings & then CPU settings. Under available governors choose SavagedZen or Smartass. I'd try them out & see which you like the most. I prefer SavagedZen, I seem to get better battery life & performance.

Personally I have never needed a task killer while on CM7, so I am going to recommend against it.

Well I had talked to someone else that is using it like that and they said they get amazing battery life
Sent from my PC36100 using XDA Premium App

I say no toward any kind of task killer. First of all, they're pointless. You're killing stuff that isn't using any power to begin with, which then restarts anyway. The task killer itself is actually doing something, running on a set schedule, where as the tasks you're killing are just sitting in memory for faster opening.
It bugs me that even the techs at Sprint recommend it, so every person that doesn't know anything about how their phone works thinks it's necessary. Then in the market for every clock widget you see everyone going "like zomg the clock doesn't keep time your app sucks 1*" because the damn task killer is killing it. That's if they can even figure out how to use it & not complain that it "won't open", despite clear instructions on how to put a widget on your screen.
Sorry, totally went off on a rant there.
But yeah, stay away from task killers & let Android do its job. You don't have to have a ton of memory free for your phone to run perfectly fine under normal usage. I don't notice a difference between 300mb & 50mb free. If you don't worry about it, you won't either.
Free memory does not equal more battery.

No. Memory has nothing to do with battery.
Screen, radios, and CPU use battery and that's about it.

Voltage control questions

I finally got srf 1.2 to work really good. I have a few questions about voltage control.
1. Is it safe to overclock and undervolt?
2. What advantages will I see from undervolting, longer battery life?
3. Does overclocking really make that much difference, and is it safe?
4. Is there a how to, or a guide that can show me how to do it?
Thanks

Yes its safe just don't use the set on boot feature. As for battery improvement some people notice a difference and others don't I personally do undervolt. As for the guide just mess around with it for a while everyone Has different Preferences so results will always be different. I don't undervolt below 75 cause when I do I get lock ups. If you lock up just pull the battery and you'll be fine. I also recommend to use journaling ON cause if you lock up and pull the battery with journaling off you might get data corruption.
Hope this helps.

What kernel are you on?
I'm on Twilight and can overclock to 1.3ghz with full stability. I don't undervolt. Combination of my phone doesn't like it and I'm not looking to save that little battery to get wakelocks (phone doesn't come out of sleep mode because the processor speed is too slow or doesn't have enough juice to make that push.)
If you're using a kernel that can go to 1.4 or 1.5 test it for a while before you save your settings. Also consider buying the paid version. It allows over volting which may allow you to supply enough power if 1.4 or 1.5 causes freezes.
The app is pretty basic. The top bar on the first screen is how low you allow the processor to go in speed. The bottom is how fast. Lower than 100 mhz causes wakelock for me. Or used to. Haven't tried since. My settings are 200-1300 mhz. Second page is voltages. They start at default. If you have extreme, moving them to the right will overvolt and give those speeds extra power. Moving the slider to the left undervolts. Some people can only undervolt at the lowest speeds of say 100-400 mhz. It's a lot of trial and error. Have fun though!

So on the main page my settings are 200-1300, then I press apply settings. How can I tell If it is working, it does not seem that much faster? Do I have to set this every time I turn my phone on? Do I want to save thos for boot up?

When you turn your phone off then on, does it show those same settings? The speed boost will be slight. It's not like we're resurrecting Jesus here.

(Question)(need helpp)

I'm using the setcpu app and whenever I apply a "when screen off" profile and put my phone to sleep it won't turn back on. I set it to 200-400mhz and it doesn't turn back on and I think the govenor is conservative.
I am running randomrom pheonix with genocide 2.0 kernel.
Can anyone tell me what they have their profile set as or what is a good low value I can set my phone to so that it still runs but doesn't waste too much battery life while its off. Any kind of help is appreciated.

Don't use profiles
I wish I could be of more assistance, but basically, I remember many of the more experienced forum members here suggesting that you do *not* use profiles with SetCPU on the Epic 4G.
I am running the Genocide 2.0 kernel on my Epic with SetCPU set to a max of 1120 and min of 100 MHz, with no profiles set and the governor set to conservative. Haven't had any issues.
Also, I use a widget called Temp+CPU PRO that dynamically shows you the clock speed of the CPU, so you can tell when it's at 100 MHz and so forth.
From what I've seen, the speed of the CPU ramps down to 100 MHz on its own when the phone is idle.

Oh.. well I have never seen that.. I heard ppl talking about setcpu is better than voltage control so I thought it was cuz of the profiles.
So about how many hours do u get out of ur phone? What rom r u using with that kernel?

There are a lot of good posts on here about maximizing your battery life. Most of it requires some functionality to be sacrificed, so it's all about your personal preferences.
Our AMOLED screens are purty, so even though I keep mine dim to save battery, once in a while, say when watching a movie on the phone, I'll crank up the brightness all the way to make the visuals pop. Do a few searches, read up, and then tweak, tweak, and tweak some more until you find that "sweet spot" that works for you.
Of course, hooking yourself up with one of those monster 3500 mAh batteries wouldn't hurt, either. Just sayin'

I know I read a lot and I do like everything they say but don't get the same result as they say and I use screen filter so my brightness is alwas reallly low
And idk how to use tweaks really well I found this battery tweak thing and I believe all it really does it change the mhz the phone runs on but I could b wrong
And I used supercharge v6but idk if it works I don't notice any changes.
So now I just changed to eh17 modem and removed all apps I don't use and only have a few. I froze the thingsi know waste battery and I don't have nothing thatuses the battery I think.. so is there any tweaks u know r good?

Make sure you freeze sns and drm services with a bloat freezer of mybackuppro's toolbox tht saves me like a couple percents of battery an hour. Also I have tried setcpu, voltage control, pimp my cpu, but my favorite overall is tegrak

Don't they cost like $70???

I wouldn't use the screen off profiles. You only would need them if your trying to have your phone never go into deep sleep for some reason. Not to say the settings would cause this, but your phone should hit deep sleep after 10 or so seconds of screen off making this setting quite useless. Also if your running genocide you need to be using on demand! You can set the throttle up % in the advanced tab of setcpu. If you wanna utilize profiles what I do is set it to throttle down the cpu as my battery dies. Saing juice for those crucial lower percentages.
Cd's or tapes?

I'm saying don't bother with the screen off profile, first of all. Secondly don't run conservative with genocide! Its geared for ondemand (unless your trying to save your battery by not overclocking at all) and ondemand is configured by going into the advanced tab and configuring the usage percantage of your cpu to switch to the next highest frequency at a certain percentage. I use 98% and I get pretty darn good battery life. I don't know if it helps or not, but I also set powersave bias on 25. Just post if I'm still confusing you.
Cd's or tapes?

No I get it now ur talking about the up threshold right?
I flashed this battery tweak and I went to check it right not the up threshold is set to 95 I guess the tweak changed it cuz I remember checking it before and everything said -1. But thanks I get it. So if I had my phone set to 200-1200mhz and ondemand and when I have a high battery level I higher the thrshold and as I lost battery I lower it...?

Do we need SetCPU apps when we have CM 7.0.3 Stable ?

I am a newbie on rooted phones. Just rooted the phone to CM7.0.3 Stable and found out that we have a setting to change the Govenors, currently set using SMARTASS with 245/729.
One question, is it nessesary to install apps such as Setcpu to overclock? or it is just adequet to use the setting in CM7 ? Will both conflict each other? Many thanks

Its useful I think, because you can setup CPU speeds for certain things, such as when your screen is off or when the battery drops below a certain threshold.

depends on you need dude. playing games/ watching videos/ hearing music/ simple phone usage/ battery conservation etc. stock one dont have profiles. but 3rd party like set cpu have it. so that it auto switches profiles according to ur present phone status.

[Q] SleeperRom DRM Service killing battery?

I froze all of the DRM services as shown in the picture below, yet it is still hogging battery resources as shown below.
Does anyone know how this is possible and how to fix this?
I'm using SleeperRom 1.0.11 and Shadow Kernel 1.03+.
Thanks.

That doesn't help. Percentages don't mean anything. ALL your applications have to run through android system. Take off android from your phone and you can't run anything. To see what is using your battery check Betterbatterystats. What files have the most time on them? Check processes and partial wakes if your battery drains while your phone is in standby. Also get CPUSpy and make sure your phone goes into deep sleep when in standby and not on charge.
Just because it lists DRM in the android system does not mean it is using more than a second or two of quick checking services. This is why some apps screw up if it is removed instead of just frozen. It has to check if the files are still on your phone.

Thanks, i'll try that app. I assumed that since it was at the top, it was using the most. Since updating to SleeperRom 1.0.11 and Shadow Kernel 1.03+, my battery does not seem to be as good even though I have not changed the way I use my phone. This is why I was investigating.
after checking betterbatterystats, I don't even see the DRM service anywhere within the app, so I guess that is good.
I guess my phone just doesn't agree with the update to sleeper 1.0.11 and shadow 1.03+

I have not tried that combo but is there a default overclocking setting? I tried SleeperROM before and it defaulted to 1100 Mhz overclock. If you came from a ROM with no OC set then that would explain it.

If you set that as apply on boot after the wipes if you mean data wipe, and install then it should be 1000 max. Easiest way is just check CPUspy. Have you changed brightness on your display? Did the ROM add any apps like Gtalk with video that you didn't have before that may need to be frozen? Definitely get Betterbatterystats and check what's running.

I think the major difference is the shadow kernel and the use of voodoo color. I was previously on samurai 2.0.6 or 2.0.8 i think.
I have always had auto brightness on. Betterbatterystats did not reveal anything out of the ordinary.
I guess i'll just try a new rom/kernel combo and see if I can get better results. Thanks for your help Kenny. Betterbatterystats is a nice tool i had not known about.

No problem. I did find that voodoo color and the voodoo control app use a little extra battery plus having to increase brightness a little with voodoo color used up a little more battery.
