Yes busybody is installed. The curious thing is that default scheduler is zen, default read ahead is 1024 as expected. There seems to only have problem with governor. I will check between your script and the other settings and let you know.

Is there anywhere I can find documentation on the sound settings? Or at least a starting point?

I mostly use the phone's speaker and very occasionally headphones. I'm interested in increasing the volume, especially for pocket use in a noisy environment.

EDIT: in an effort to provide enough information so someone can help, I should have added that I have the paid version of Trickster. I also realize this isn't as glamorous a subject as tweaking every last drop of performance out of the phone, but I do hope someone can at least give me a direction to follow.

the supersu daemon, a userinit.d, and one more.

the supersu isn't the issue, the userinit.d just tells it to run anything in the data/local/usedinit.d folder as far as I know (that's where mine is at), and the banner one doesn't even have anything in it other than an omni graphic:

that's why I'm stuck. it seems like there has to be something else changing it, but I have no apps other than trickster that would do that, and trickster isn't set to run on boot.

I am using the otg version 43. I'll try the script on stock to make sure it works there. is there a way to delay the running 30 seconds or so after boot? thanks!

i removed all the mpdecision stuff and it works fine on stock. on omni it can't set the governor, and on PA it sets everything correct but still shows the mpdecision toggle turned on in trickster. omni was also changing the frequencies randomly, so there's definitely something going on there. oh well, i know it's not the kernel and it's not the script either. also, it works on stock, which is what i use 99% of the time anyway. thanks for the help guys and for the fantastic kernel! :good:

[Nexus 4 General] hellsgod:
Just for fun some of my thoughts why I think it's not necessary to lower the min freq more:

With 81mhz your phone simply can't handle much background load. So you'll have more frequency scaling. More scaling means more battery drain. So it can be more battery friendly to have a frequency in the middle, 192mhz for example. Why do you think qualcomm took 384? It can handle some background load without scaling up. Listen to music is no problem at 384, even at 192 its possible. But you'll have more scaling (jumping between 192 and 384).

Use a kernel which gives you that and decide for yourself if its worth to have it. I don't see a need for it. Many experiments show that even a higher min freq (500 mhz for example) can improve battery live, because it don't need to scale up that much with some background load. Lower doesn't mean more battery.

[MENTION=647113]hellsgod[/MENTION] nicely said! I just switched to hellsDoctor to check out this new low frequency thing. The phone is running fast and smooth with Wheatley by default. I am aiming to get less battery drain during sleep, let's see if this one helps. But I guess deep sleep state is not linked to the lowest frequency in the table right? so when the phone sleeps it goes to sleep cpu state and not to 81 mhz am I correct?

You know, there are absolutly no evidence, that even 192mhz increases battery life. I've seen many stock kernel user which have about 5h dot. In my N5 kernel I didn't even lower the min freq and increased dot. There are some evidence, that the device, in fact, wouldn't go lower that 384, even if you set it. But that's not for 100% sure.

[Nexus 4 General] fricoGER:
I didnt know that, i read at AK thread that lower freq for example 162 ,that he uses, would use 1.5 less battery than the 384 step. That was the reason i asked to put the 81mhz step in your kernel. I thought that would increase battery life a bit. But what you explained makes sense and iam gonna try to raise the min freq and check out in which way it will effect the battery life.

I think it makes a difference when you're not using all your cores at high frequency, if 2 cores are online, CPU0 will be @ 1GHz for example and the other (CPU1) will be resting at 81mhz, but it's almost impossible for CPU0 to rest at 81 mhz unless the phone is doing nothing.

[Nexus 4 General] Reed-Sternberg:
you're right, however I put this idea to test on your kenel and ak's 162 several times. I run for 90 minutes every day while streaming music over lte on Google music AND Endomondo sport tracker with gps and audio coach. After the 90 minute session, I check my cpu usage, and amazingly it's at the lowest clock speed for about 85 minutes of that period.

While the behavior you described makes sense, there are some situations that you'll benefit from the lower clock, if the device affords to stay on it.

However I did not try ak's 81, I read from the feedbacks that in that case it doesn't stick for long.

Cheers
[Nexus 4 General] hellsgod:
In theory a lower freq could use less battery. But if it cant stay on this in a stable way, it doesn't matter much, or worst it affects you in a negative way. Interactive for example jumps to hispeed freq, if the load reaches 99% on min freq. On 81mhz you will reach this 99% sooner and it will jump more often to hispeed freq. If you use your device, 1026mhz upwards will be used most of the time, so you won't have much effect with it.

Won't happen here. If you touch the screen two cores will be pushed to 1026mhz. If you don't touch your screen cpu0 will mostly be used = shed_mc "2" Won't have an effect as you see.

Maybe I'll have a look at it to see, what can be handled with 81mhz when I've some time. And fun of course. Without fun it's like a job ;)

Yes, I think 162mhz is an absolute minimum. My device didn't boot with it. And the difference between 192mhz and 162mhz is minor. But like I said above, if I've some time I'll look around or testing that by myself. If my device won't boot up, it will be removed without public testing. Its nonsense to allow a clock, which can lead to an unbootable device. But the whole thing about a lower min freq is like the debate about undervolting. Too much factors to give "the ultimate answer". Its usage dependent.

Very interesting!

[MENTION=647113]hellsgod[/MENTION] I have a suggestion, I don't even know if it's possible to implement this idea or not, but hear me out:

Is it possible to adjust the governor/hotplug settings so that it'll run at 81mhz when it affords to, and in case of more work load jumps first to 192mhz, instead of the heap frequency. And only after THIS STEP if it couldn't handle the workload, resumes the normal behavior as it's implemented right now in the current version.

If this is possible by any means, we would benefit from the absolute low frequency, while avoiding the unnecessary scaling to heap frequency.
[Nexus 4 General] hellsgod:
It will work that way. Let it run for some time and you'll see that. If you have no other background load it will mostly use 1st freq and 2nd. If there is a load peak, it'll scale a step or two more. The governor always tries to find a frequency, which can handle the load with > up_threshold. If you have an up_threshold of 90, the nex frequency must handle current load with > 90% (89, 88...) So if you set you up_threshold higher you automaticly scale up more conservative, means less time in the higher frequencies.

hells
[Nexus 4 General] Reed-Sternberg:
Because I tried ak's new version, and after a while the most frequencies used was 1026, 1512, and 81. There was not much in the 192 or 386. That's why I assumed the effect of 81 will be negated by too much scaling to those higher frequencies.
[Nexus 4 General] rirozizo:
in my research while building my website (www.androidbatterylife.com), i have found that the equation of CPU battery usage heavily depends on the value of the frequency, and NOT on the time spent on it.

as you guys are testing both senarios on a 30mins time period, time here is constant. And so from the equation (which i forgot), the frequency value isn't a denominator, so lower frequency will surely be beneficial to battery.

Again, we're talking 30 mins here, that's a long time, so that's a big factor (30mins*192MHz vs 30mins*81MHz)
