Is it a good idea to set a profile in SetCPU for when the screen is off to force only the lowest cpu speed? Will this prevent deep sleep?
Please post all questions in the Q & A section. Thanks! Thread moved.

It shouldn't in theory...only one way to find out!!

Hi,
I'm researching on how I can optimize battery/performance on my phone. Does anyone know how the cpu is being throttled during low demand? In particular, will the cpu remain at its lowest speed when the screen is off? Or does it throttle cpu clock speed as usual when the screen is on?

Didn't see this posted yet in the apps section, there is an app which helps in calibrating your battery. The app is located in the market and is created by an XDA member all credit goes to him. You must be rooted for this app to have an effect, I can vouche for this app as I have used both on the EVO and now on the G2X I have experienced great battery life after using this in conjunction with setcpu.

Out of curiosity, what are people using for the settings on SetCPU (ie max and max). Also, I noticed the "Scaling" option is grayed out on my G2x over my old Nexus One. Does the scaling option require a custom kernel I am guessing? Thanks.
Also, What settings are you guys using for Juicedefender?
I guess that a good reason to root.

I am new to posting but been a long time reader.
waiting for my new phone to get here tommorrow and I am actually off from work tommorrow so I have a long time to get to know my new phone.

Does it matter if the phone is on or off when you charge it to full the second time?

All scaling does is how the CPU scales itself(to a given formula depending on the profile) for example if using a conservative scale the CPU scales itself by 15mhz depending on the task so if your min is 218 it would go up or down by 15 until it reaches the maximum or min. Since no kernals are available yet for our device it will use the default scaling profile built in. my screen off profile is a Max 218 Min 218 with a priority of 100. Regardless of the scaling profile selected I am forcing the CPU to down clock to that set of perimeters
So what I use for SetCPU is
Profile : Screen off
Max 218
Min 218
Priority 100
You dont get lag when unlocking with these settings?

No, i have the same settings and even with those settings i can listen to music and have led notification with no problems, and than right when you turn the screen on, depending on your settings of course, will bring the max right back too 1000.
Yeah it lags when I turn on the screen need to press power like 3 times

I get the same, so I use 216-312 sleep profile and no problems.
how did you guys get setcpu to work when i pick a profile after launch it force closes.

From what I can tell all this app does is delete the battery stats from the system which we can do from CWM on our own. Am I missing something?

We could just do it using Root Explorer then.

Ok so I want to start using setcpu because I have heard it helps save the heck out of your battery. Is there anyone with a killer battery saving set up backup file that I could maybe restore on my phone? Also if I'm using nstool for CPU settings should I stop if I'm using setcpu? Please though, if you have a killer battery profile, please upload it and share with the world! Thanks.

Setcpu and nstools work around the same way. Use nstools and lower your CPU clock speed to you desired amount where performance is balanced.

You use setCPU instead of NStools. The battery saving is in the screen off profiles. I have found that it doesn't help all that much on this phone. Just use SmartassV2 and you should be set

What's the best screen off profile?
Sent using Tapatalk, you know, the free version.
I am think about tweaking conservative governor and create new governor based on conservative.
First idea is adding two level to cpu scaling freq 600 and 900 Mhz.
Second is that we need to reduce conservative polling timeout.
At the end i think we can use lazy governor feature, that lazy down at 1000 Mhz level.
Are there any devs, can help me with creating this governor?
I think this is the wrong thread you must as this in general questions thread

it would be nice! I'm glad if you want me to build a kernel with your governor for testing
trying to make some custom setcpu profiles and curious if anyone knows what the lowest safe cpu speed for when the screen is off and also while in a call and the screen is off?
Right now I'm on VI and I'm running 368 max and 245 min which is the lowest min for this rom. I always run the lowest on min and 1 higher for max on sleep settings. I don't encounter any issues.

Don't go below 200 when screen is off. You'll get the "sleep of death" at the most inconvenient times.

OP, you may want to look into andrev_oc or virtuous oc daemon. Both are superior to setcpu profiles.

Nope, they aren't, i have programed scripts for both and I own SetCPU. Stick with SetCPU

I have already gone under 200mhz for sleep frequencies. Android revolution goes under 200 and I would run it under 200 always till now that I'm on VI.

I run lowest at 187MHz @ 700mV without any problem. I also set my screen off freq to that. Never tried one below that freq.
Here's a little info on using an overclocking daemon vs setcpu taken from the virtuous unity thread.
Introduction to the new Overclocking Daemon
This ROM features a completelynew wayof Overclocking and managing screen states.
The History But before explaining it further, let's talk about previous solutions. There are several different approaches to achieve "screen-state-scaling". That means basically thatthegovernor changes if you turn the screen off and changesbackto normal when turning the screen on.
This is mainly used to restrict the amount of CPU usage (the frequency in fact) during screen off. This can lead to a major battery life increase.
The solutions so far were:
Apps likeSetCPU,which changeautomaticallythe governor based on profiles Integrated solutions in the governor itself
Both these solutions have major problems.
The one with a tuner app is always a little laggy right after turning on the screen because SetCPU (or any other CPU tuner) needs some time to change the governors (up to 7 seconds). This leads mostly to major lag in the lockscreen.
The second solution is the smartass governor. It has already a screen-state-scalingincluded,so it reduces the frequency when the screen turn off. This could be a really nice solution but it has some problems too. Smartass most of the time is not really stable and has problems with its frequency scaling.
Be aware that the daemon only works if all CPU tuner apps are deinstalled. Otherwise it deactivates itself.

Thats very low. Surprised you do not get any issues.
Wish I could find the thread, but I was on a custom ROM that set the minimum CPU frequency to something below 200 by default, and I couldn't send text or MMS messages. Really weird.
