Hi,
I'm using Co-Core 8.2 and I want to test One Power Guard to improve my battery life.
But I don't have any idea about which CPU governor and I/O scheduler to choose.
Could someone tell me which combination provides the best balance between power-save and performance?
I'm on Jelly Bean 4.1.2
NB. Cocafe recommends PegasusQ as CPU governor and either SIO/ROW for I/O scheduler but I would like to get some feedback from people already using One Power Guard.
Thanks in advance

Pegasus and sioplus
OR
Hotplug and sioplus

Thanks for the answer. I will give a try with Pegasus
However I noticed that sioplus is not available on One Power Guard settings. Only row and sio.
Is sioplus available in Co-core 8.2?
These apps like this just drains your battery. If you want play with CPU, download a CPU controller app. (like SetCPU) and install CoCore 9.0 which is newest version.
When you don't use phone ; 600 MHz Max & HotPlug
When you don't use phone V2 ; 600 MHz Max & Ondemand & deeper sleep status
When you lock phone, don't decrease speed (too much) because it will use whole CPU if it needs ; 800 MHz Max & Ondemand Q/Lulzactive Q/Pegasus Q
When using ; 1000 MHz Max & Ondemand/Interactive/Lulzactive Q/Pegasus Q
When you get mad and crazy about performance, lock the min to max; 1000 MHz min and max & Ondemand & SmartAss (still exists or not I don't know)
If you increase minimum speed it will keep it. So I suggest always keep min to 200MHz. (if exists 0 MHz I don't remember it too)
Edit: and don't go deeper sleep if you use hot plugger governors like Hotplug, Pegasus, Lulzactive Q

Thanks guys,
I will compare the battery draining with One Power Guard just to give it a try.
If I don't notice any improvement then I will tweak with SetCPU

Hi again,
What exactly do you mean wit "deeper sleep"?
Is that an option or when the display is off after several minutes?
Sorry for my ignorance

Go to the CoCore's thread you'll see. It's deep sleep level which can increase your battery life when you don't use the device. It's not about using, it's about when it's stand-by.
Ok
After one day even if One Power Guard is a nice app I prefer to switch governor depending on the display status. So I was thinking about using tasker (instead setCPU) which is already running on my phone and this way not adding more background processes.
I set a couple of task using the CPU control from tasker. It is working fine switching governors but I noticed that the frequencies (min and max) don't change. I tried even with shell script and still I don't get to set the max frequency. Then I prefer to make you a couple of questiosn:
-In tasker when using the CPU control. If I change governor. Should it be set in both CPUs (0 and 1) or only in a single one? In my case i set the governor in both.
-I use the terminal to check the current governor and max frequency (for instance for the cpu0)
cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governorcat /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
As said above the governor is succesfully changed but that's not the case for the frequency. Then I tried to run a shell script to change the max frequency as follows:
echo #frequency > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
But it seems not working neither. So I wonder if I'm doing something wrong.
NB. By the way I'm happy using the governor hotplug while not using my phone (thanks for the advice). In normal use I set pegasusq with sio and seems working great.

Unfortunately I can not post to dev section, so hopefully stratos will see my post here:
I had stock JVR with semaphore 1.5 (not v) on ext4 and everything was excellent with this brilliant kernel apart from the well known phone fc.
OC/UV was ok: quadrant scores were approx 1900-2400 on conservative cpu gov and 2500-3000 on ondemand gov.
Now, I flashed the 1.6 beta and my system is noticeably slower on *conservative* cpu gov and quadrant scores dropped clearly below 1500. Ondemand cpu gov seems to work ok but as I was alwaus on conservative I can not be abs.sure
I don't know if it is important but using voltage control app to check cpu function I see that:
a) cpu freq is wildly/unpredictably fluctuating with 1.6beta while this was not happening in 1.5 under conservative cpu gov,
and
1b) reported default voltage is different: for example with sema1.5 1200mhz had default 1275, now in 1.6beta without oc module 1000mhz is 1275 but with oc module 1200mhz have 1300mv by default.
Stratos,
could it be that a) something is broken in the new conservative cpu gov? , b) have you changed the default cpu voltage between v1.5 and v1.6beta?

Unfortunately I can not confirm your results. I just load the conservative governor and tested with and without overclocking. No problems here.
During benchmarking due to high load the frequency it's difficult to drop below the max. So, governor should not make the difference.
The uv value was the same in 1.5.0 (1300mv) for 1.2Ghz but it was wrongly displayed as 1275.
Thanks for you feedback. I will let you know if someone else report problems about the conservative governor.
Hey stratos, thanks for the clarification about cpu voltage.
Re cpu gov, I just did a nandroid restore and confirmed that conservative cpu gov works much better in 1.5
Any ideas on how to explore it further? There is definetely something different here.
I mean, its not just quadrant scores, its memento database loading instantly vs seconds of delay under cons cpu gov in 1.5 vs 1.6beta.
I will reflash again l8r tonight.
Anyhow, this kernel rocks! And I love the tun/netfilter module design.

HELLO AND SALAM SATU MALAYSIA
Since i was newbie about android,
i try to overclock my Xperia X8.
so i went to market and i found Antutu CPU Master.
the problem is i found something that i never heard before.::::::
"GOVERNOR"
could someone told me..what is governor actually...
and what different better the governor module?
i only found about smartass..the other module..i didnt find in xda forum.
i hope someone could help me here..before i accidentally brick my phone.
Cpu governor is control the Cpu freq.
- The OnDemand governor is the default option used by Android. It scales the CPU speed between the minimum and maximum speeds depending on CPU load. If the system needs more speed, the kernel will rapidly scale up the CPU speed.
- The Conservative sets the CPU speed in a similar way to the Ondemand governor, but scales the CPU up much less rapidly. This would theoretically save battery power, but may lead to less responsiveness.
- The Userspace governor is currently useless. It’s another way for applications to set the CPU speed that setCPU does not use.
- The Performance governor always keeps the CPU at the maximum set frequency.
Additionally, he makes reference to another option, which is not currently part of the setCPU app, so I am assuming that this is one that was removed in later versions.
- The Powersave governor always keeps the CPU at the minimum set frequency.
- Except for “Userspace,” no matter which governor you set, the CPU will always stay within the bounds of the maximum and minimum speeds you set in setCPU.

so far,i didnt find any bug.
wifi n vib work very well with my linuxperia arch v1 rom.
i use antutu benchmark..i get 1881..
superb ..thanks a lot.
1881 good. Do you like LinuXperia v1 ? Come soon LinuXperia Esca Arch 3 ( overclock, bravia hack, xloud, dsp manager vs )

I'm a slightly android noob. but What are Governors i kept hearing about, especially on the AbyssNote kernel thread page.
angelom said:
AbyssNote kernel 3.3 Original Logo
Changelog:
Changed conservative governor
Changed default governor ondemand with sampling rate of 100000. use setcpu or scripts to lower it (or try conservative governor) if you prefer performance over battery life.
Changed lulzactive governor so that it uses idle notifier + some other tiny tweaks
Added Hotplug Governor
Changed Wifi drives...

Does it refer to the SetCPU's profile option?
And by the way when we set the profile on SetCPU, does it automatically help us to undervolt the Note? Or undervolting is left to the user to set?
For a guide on govenors take a look at this
Govenors
i dont oc or uv bbut these are normally set by the user, many threads have recommended settings
I'm currently on Zeus v7.01 with dianaV2.3+ kernel and I'm wondering what is the best combination of Governor/IO Scheduler/Voltage to obtain the most best battery life.
I'm not searching for best performance honestly, but instead a longer lasting phone. lol
I rarely play games, and smoothness is not a must for me (Nemus Launcher does the job, smoothest launcher ever!)
My current settings are:
CPU Frequency Tweaks
Max freq: 1000
Min freq: 100
DVFS enabled on boot
Voltage Tweak: -5
Governor: ondemandX
Io Scheduler: sio (Simple I/O)
You could try undervolting your phone,because i like performance and smoothness,my setup is like that:
Max CPU frequency:1300Mhz
Min CPU frequency:300Mhz
Governor:Smartassv2
I/O scheduler:deadline.
Sorry for useless stuff,but i like to share
My main agenda is to help, not gain thanks.

No no it's nice to share your experience!!
Might help others..
Hmm my phone is already UV... -5, if i decrease further wouldn't it be too low to cause instability?
And about IO Scheduler, i don't quite fully understand it.. which one drain least battery?
i am using 100-800 smartass2 sio and -7V without any problems.
I know that default cpu governor of note 5 is "Interactive". It gives snappy performance but high battery drain.
The most thing I care about always is the battery drain so I want to change the cpu governor of note 5.
I had already rooted my note 5 and I am looking for some possible way to change the cpu governor of note 5.
Anyone has ideas?
Thank you!
I just tried to use "Kernel Tasker.apk " to find out what I can tweak for the kernel.
Only "userspace, Interactive, Performance" these three cpu governors I can choose......

if u really want to tweak governor, frequency and other stuffs like this.. Try skyhigh kernel by upintheair.. It gives u access to all these settings..
