Hey
After I rooted (and reflashed) my Z5C, I noticed that the battery was draining very quickly. Then I found out that it had been running on max frequency w/ the performance governor. So I wanted to ask if anyone knows the default/stock frequency, governor and scheduler? And for some reason it sets itself to performance and on the highest frequency so I have to set it manually apparently...
Kernel auditor can possibly help

I'm looking at the governors in Ziggy's kernel packed with Gingeritis3D and I've got some questions I was hoping someone could help me out with.
For smartass, there are some that aren't standard. The seem sorta self-explanatory, but I was wondering what the following are exactly and what the values mean:
Up_rate_us
down_rate_us
ramp_up_step
ramp_down_step
sample_rate_jiffies
For the lagfree governor I'm curious about the following:
sampling_rate_max
sampling_rate_min
sampling_rate
sampling_down_factor
freq_step_down
My last question would be:
Why does this kernel go horribly unstable as soon as a I mess with any of the smartass values. I've screwed with these on other kernels with no problem and no matter what I do, any adjustment to the smartass gov values yields a completely unstable device.
As title says, what is the best setting to be chosen?kindly brief the detail coz im newbie

Well it depends on taste and kernel support but for me the best will be interactivex as governor and sio as I/o scheduler, it gives you no lags and good battery life.
i installed x kernel v4, did not have to change the cpu governor or i/o.
i only install nofrills to do benchmark, then removed it afterwards.
best battery life ever on hybrom v16
i think it uses ondemand for cpu, not sure wether it uses noop or deadline for i/o
i am currently testing smartassV2 cpu governor with simple i/o scheduler on krsh3 kernel
so far battery time is better with these settings than the default ondemand governor

I've read that pegasusq should be aware of multi-core CPUs and should be able to deactivate not-needed cores.
But, on SGS2 a lot of people keeps using ondemand. Even CM keeps ondemand as default scheduler.
Is ondemand still better option as maybe it is better to run one core at 200MHz using ondemand then one core at 500MHz using pegasusq... ?

This could be helpful.
Please search next time as I just typed "ondemand vs pegasusq" into the search bar.

thx for pointing out, but in that thread I've just found things that I already mentioned: pegasusq is made for multi-cores and it has integrated hotplug.
unfortunately, I had no chance to find any real-world use comparison of pegasusq and ondemand (or other schedulers) regarding power consumption nor responsiveness.

pegasusq in my opinion is the better governor to use, largely because it can tell if is more than one core and respond accordingly. Pair that with CPU Sleeper Dual Core and you're golden as far as power saving awareness. SIO I hear is the best i/o scheduler to use for power consumption, deadline in my opinion is the best for pure performance however be careful because If you do overload and a process misses a deadline it will hiccup or even freeze.
Hello guys,
I am using CM11 build 7 latest update. I am experiencing a issue in it.
i am using Interactive governor and Row I/O. but my processor's speed not going down below 800Mhz. its always on 1Ghz-800Mhz. even i set 200Mhz as its minimum speed. tried to enable Powersaver governor but its still does not goes below 800mhz. please help.
battery backup also affected by this. sorry for my bad English.
Edited
yup, got the issue solved by changing the governor to OndemandAX
Um, maybe it's a stupid question but is the InteractiveX governor ramp up to highest possible maximum frequency or just to User maximum configuration freq? Im asking because it is not stated.
