i've been doing this since the last 5 hours.

i read that setting ignore nice load to 1 conserves battery and setting the uptreshold and sampling rate to 75 and 150000 respectively improves responsiveness (but theoreticaly consumes more power) and these settings are present in ideal, xlv, ulv and starving.

so is it okay if i also made those changes in stock and save it?

Code:
kernel configuration file generated by /usr/sbin/kernel-config
MINFREQ=125
MAXFREQ=600
FREQS="0:30,90 250:38,180 500:48,360 550:54,400 600:60,430 700:60,430 750:60,430 805:60,430 850:60,500 900:60,500 950:60,500 1000:60,500 1100:72,520 1150:72,520 "
SMARTREFLEX_VDD1=0
SMARTREFLEX_VDD2=0
GOVERNOR=ondemand
IGNORE_NICE_LOAD=1
UP_THRESHOLD=75
SAMPLING_RATE=150000
POWERSAVE_BIAS=0
my deepest thanks

UPDATE: im trying it currently and yeah, it slightly improves responsiveness, I just need to be advised if these changes are safe running on the stock settings.....

Everybody is talking here to put samplingrate lower.
This will cost more battery and i think is not needed.

I am trying this for the last week:
Sampling_rate on 700000
Up_threshold on 65
With an minimum off 500mhz.

Sampling_rate and up_threshold are bind together.
What i mean is Every 700ms there will be taken a look how much average CPU usage there is, if it exceeds 65 it will upscale.

Result is a longer battery live, CPU stays more @ 500 mhz or other lower frequencies.
On 500mhz you have already a little bit power is say, so the 700ms you will not notice.

With a 500mhz to whatever mhz I think this is overall better for the CPU also.


Still i can maybe finetune this, because i think 700ms is much but it feels very nice with these settings and overall my experience is better.
Or lower the threshold a little bit more, but i like it already @ this settings.


sorry for my english I think, but i tried.

Please comment because i think this works pretty damn well.

yes we are aware of that, i am concerned of improving responsiveness.

i notice it as per my usage, and OC settings are as well set up with lower sampling rate and uptreshold than stock

Hi guys i need a little help, im trying to use the alarmed app to set different freqs for different times of the day/night, im using the same command im using in my QB widgets "echo kernel-config load sleep | sudo gainroot" but its not working.

I would really appreciate any suggestions.

Thanks

No joy. Still not doing anything, ive pretty much got everything else the way i want it now, but it would be really cool if i could have it automaticaly switch between ideal and sleep. i guess ill just have to keep trying till i work it out. thanks for the reply though.

have you tried the normal echo code? like echo sleep > /usr/sbin/kernel-config
