[Unofficial] setCPU Settings

[Art Vandelay]

Im curious how low people have gotten then 180mhz. Lowest I have seen posted is 875 (higher than 320mHz). I have been running at 800 without any problems. Anyone try lower?

Axiom 2.4 with LeanKernel 180-1200 InteractiveX. Moderate usage --> 40-50% battery life after 12-14 hours.

1420 --> 1400 (not using)
1350 --> 1225 (not using)
1200 --> 1175
920 --> 1050
700 --> 975
350 --> 850
180 --> 800

Is the phone even usable in the 180mhz slot? I can't imagine your phone spending much time in this state. 350mhz seems low enough for to and than there is deep sleep for when your phone is idle. It seems like anything with having the screen on would require more than 180mhz.

Very stable, I don't feel like taking a screenshot and uploading,...
But my CPUspy info is

1200 0%
920 0%
700 1:39:57 5%
350Mhx 5:12 0%
180Mhz 14:50:48 53%
Deep Sleep 11:17:02 40%

Axiom 2.4 has never frozen, rebooted, or any other badness. (And that's why I love it DancingNexus )

Im testing these. Working well so far, but will be another day or 2 before I can call them stable.

1420 --> 1400 (not using)
1350 --> 1225 (not using)
1200 --> 1100
920 --> 1000
700 --> 900
350 --> 800
180 --> 750

0% at 1200 and 920. You must not use your phone at all. Do you think if you eliminated the 180mhz slot your phone would spend even more time in deep sleep? Or would those 15 hours be in the 350 slot. What I am saying is, it would seem the 180 slot is only used with screen off, but wouldn't that be better served in deep sleep.

Is there in app that will display current slot in the notification bar? So that when you are using the phone you can see what apps are utilizing what slot?

This weekend have used a the phone a little less than a normal weekend, that probably why the 1200 is 0%. On average it's around 3-4%. But most tasks are done with 700, phone calls, texts, Gtalk, most web surfing.
I dont think eliminating the 180 would help. If the phone wants to sleep why would the voltage slot matter? When the phone is idle, aka playing around with setcpu it's at 180 or 320.
There is likely a notification widget, but that would consume CPU thus skewing the results. For now I'm happy with my and other's empherical data.

I did have a freeze when switching between apps on my test settings so changing 180 --> 775

Yeah you may be right. I was just curious that is all.

What I would like to know, which I haven't found out yet, is what causes dead sleep

Deep sleep can only happen when no other apps are running.

I think there are 2 big offenders that most people over look b/c they show up under the mystical battery consuming 'android OS' (mine averages 10-20% consumption with a ridiculous keep awake time)
- Camera sensors staying open on boot (credit Franco)
- Notification apps keeping the phone away (Lightflow, missed reminder, stock, whatever)

I think the real question is what is the benefit of deep sleep over lowest kernel setting? Data/radios are the same, so what gain do you get? So why not try to get the lowest voltage and clock to save battery when not using the phone. I have Googled this without an satisfactory speculation.

good point. That's what I am trying to find out too, how does the phone benefit from deep sleep over the lowest kernal.

Over night, my phone will be almost entirely in deep sleep, but still drops about 10% in 8 hours.

Can someone share their setcpu profiles and settings please? Much appreciated.

Is anyone on the Lean Kernel?

I'm on Lou's Defiant kernel. Not all the bells and whistles other kernels have, but its rock solid and completely optimized.

 

[BenLand150]

I've been using Lean Kernel lately. And it's been amazing.
